The fermentation tank 1 is used for treating livestock and poultry wastes, such as livestock and poultry manure and the like, and is one of better measures for solving the problem of environmental pollution caused by the livestock and poultry wastes and realizing the fermentation and utilization of the livestock and poultry manure at the present stage. However, in some alpine regions in China or winter, the fermentation effect of the livestock manure is possibly poor due to the low temperature. In the process of treating fermented livestock and poultry manure, the fermentation tank 1 discharges a large amount of odor carrying heat. The residual heat of the odor cannot be recycled, so that the energy consumption is improved, the resource utilization of the waste gas is not facilitated, and the problems of incomplete fermentation of the livestock and poultry waste due to too low temperature and the like exist. Therefore, the present application provides a waste treatment apparatus, which aims to solve the above technical problems.

A waste treatment apparatus, as shown in fig. 1, comprising: a fermentation tank 1, an impurity removal unit 2 and a purification unit 3;

the fermentation tank 1 comprises an inner tank body 11 and an outer tank body 12 which are nested with each other, and an interlayer 101 is formed between the inner tank body 11 and the outer tank body 12;

an inlet of the impurity removing unit 2 is communicated with a filling opening of the inner tank body 11;

purification unit 3 includes waste heat pipeline 31, pipeline 32 and clarifier 33, and clarifier 33 is connected with edulcoration unit 2, and waste heat pipeline 31 one end is connected with edulcoration unit 2, and the other end communicates with intermediate layer 101, and intermediate layer 101 passes through pipeline 32 and is connected with clarifier 33.

The device provided by the embodiment of the invention at least has the following beneficial effects:

according to the waste treatment device provided by the embodiment of the invention, the livestock and poultry waste is placed in the inner tank body 11, the impurity removal unit 2 is arranged to be communicated with the filling opening of the inner tank body 11, so that dust and impurities generated by fermentation of the livestock and poultry waste can be treated, and the odor generated by the waste can be purified by the purification unit 3, so that the odor is prevented from entering the atmosphere to pollute the environment; and through setting up waste heat pipeline 31 and purifying tube 32, the fermentation temperature is too low in fermentation cylinder 1, can pass through waste heat pipeline 31 with the gaseous of fermentation production and introduce the intermediate layer 101 when the fermentation needs abundant heat, provides the temperature for the fermentation of discarded object, has improved heat utilization efficiency. Meanwhile, the problem that the livestock and poultry manure is not thoroughly decomposed due to too low temperature is solved.

The apparatus provided by embodiments of the present application will be further described below by way of alternative embodiments:

as an example, the fermentation tank 1 provided in the embodiment of the present application further includes an end cap, and the end cap covers the fermentation tank 1. The end cover is provided with an air vent, and the impurity removing unit 2 is communicated with the air vent.

As an example, an apparatus included in an embodiment of the present application further includes: the agitator, the agitator setting is in fermentation cylinder 1, stirs constantly through the agitator waste in to fermentation cylinder 1, increases the fermentation of waste, improves fermentation efficiency.

By providing the interlayer 101 between the inner tank 11 and the outer tank 12, the waste in the inner tank 11 can be cooled, heated, or kept warm by the interlayer 101. The fermentation tank 1 adopted by the related art generally adopts the interlayer 101 to achieve the heat preservation effect on the inner tank body 11. However, when the temperature in the inner tank 11 is low, the inner tank 11 cannot be heated. The device that this application embodiment provided through setting up edulcoration unit 2 and purification unit 3, can return the gas of arranging outside after handling to intermediate layer 101 when the internal temperature of jar is lower, heats internal jar of body 11. So, on the one hand, improved the utilization ratio of resource, on the other hand has still guaranteed the fermentation temperature in the inner tank body 11, has guaranteed the normal clear of fermentation.

The capacity of the fermentation tank 1 can be determined according to the amount of waste to be fermented. As an example, when the content of the fermented waste is small, the capacity of the fermentation tank 1 may be small; when the content of the fermented waste is large, the fermentation tank 1 of a large capacity can be selected.

In an alternative embodiment, as illustrated in fig. 2, the dedoping unit 2 comprises: a cylinder 21, a filter layer 22 and an adsorption drying layer 23 which are arranged along the radial direction;

the filter layer 22 and the adsorption drying layer 23 are located in the cylinder 21, and the filter layer 22 and the adsorption drying layer 23 are respectively located at the inlet end and the outlet end of the cylinder 21.

It should be noted that, since there are many dusts and other impurities in the waste, the dusts and impurities will overflow together with the gas, and if the dusts and impurities are not treated, they will accumulate for a long time to cause the blockage of the residual heat transfer pipe 31 and the purge pipe 32. The embodiment of the application processes dust and impurities accompanied with gas overflow by arranging the impurity removal unit 2.

And a large amount of acid gases, such as sulfur dioxide, carbon dioxide and hydrogen sulfide, are accompanied in the gas overflowing from the fermentation tank 1, and if the acid gases enter the residual heat conveying pipeline 31 and the purification pipeline 32, the residual heat conveying pipeline 31 and the purification pipeline 32 are corroded, and the cost of the device is increased. Therefore, in the embodiment of the application, by arranging the drying layer, on one hand, moisture in the gas is absorbed, and on the other hand, acid gas in the reaction gas is absorbed, so that the corrosion of the acid gas to the waste heat conveying pipeline 31 and the purification pipeline 32 is avoided.

It is understood that the presence of dust and impurities in the gas may affect the absorption reaction of the reactant of the adsorption drying layer 23 with the acid gas and moisture. Therefore, the present application arranges the filter layer 22 at one end close to the fermentation tank 1, i.e. the impurities in the gas are removed first, and then the gas is subjected to the adsorption drying treatment.

In an optional implementation manner, the device provided in this application example further includes a plurality of support rods and a filter screen, the plurality of support rods are arranged along the circumferential direction of the cylinder 21, and the filter screen is connected with the support rods to form the filter layer 22. As an example, the mesh number of the filter screen can be 200 meshes and 230 meshes. For example, the mesh size can be 200 meshes, 210 meshes or 230 meshes.

In an alternative embodiment, a discharge hole 220 is disposed below the filter layer 22, and the discharge hole 220 is used for releasing the impurities filtered by the filter layer 22.

It will be appreciated that the filter layer 22 will filter out most of the dust and impurities in the gas, which when accumulated more will result in clogging of the filter layer 22 and reduced gas flow. Therefore, by arranging the discharge holes 220 below the filter layer 22, when more dust and impurities are filtered by the filter layer 22, the dust and impurities can be discharged through the discharge holes 220, thereby improving the filtering effect of the filter layer 22 and improving the fluidity of the gas. For example, the size of the discharging hole 220 may be matched with the size of the hand hole, so as to facilitate the extension and retraction of the hand of the person.

Therefore, the influence of moisture on the subsequent removal of the acid gas can be avoided.

As an example, the adsorption layer may be a granular potassium hydroxide adsorption layer. The material of the adsorption layer in the embodiments of the present application is not limited thereto, as long as the effect of absorbing acid gas can be achieved.

In an alternative embodiment, as shown in fig. 3, the waste treatment apparatus further comprises: a first valve 4, wherein the first valve 4 is positioned between the impurity removing unit 2 and the purifier 33.

It should be noted that, according to the apparatus provided in this embodiment of the present application, when the fermentation temperature of the fermentation product in the inner tank 11 is low and it is necessary to heat the fermentation product, the first valve 4 is closed, and the gas enters the interlayer 101 between the inner tank 11 and the outer tank 12 through the residual heat transfer pipe 31 to heat the inner tank 11. Thus avoiding resource waste and improving the fermentation rate of the wastes. After entering the interlayer 101 for circulation and heating, the gas flows through the purifier 33 through a second pipeline communicated with the interlayer 101 for purification treatment.

In an alternative embodiment, as shown in fig. 3, the waste treatment apparatus further comprises: and the second valve 5 is positioned on the residual heat conveying pipeline 31 and between the impurity removing unit 2 and the interlayer 101.

When the fermentation temperature of the fermentation product in the inner tank body 11 is higher and the fermentation product does not need to be circularly heated by gas, the second valve 5 is closed, the first valve 4 is opened, and the gas is purified by the impurity removal unit 2 and then enters the purifier 33 for purification.

In an alternative embodiment, as shown in fig. 3, the waste treatment apparatus further comprises: and the pressure sensor 5 is positioned on the waste heat conveying pipeline 31, and the pressure sensor 5 is positioned between the impurity removing unit 2 and the second valve 5.

Through setting up pressure sensor 5, can real-time supervision follow the gaseous pressure of fermentation cylinder 1 play, and then the adjustment lets in the gas content that intermediate layer 101 carries out the heating.

In an alternative embodiment, as shown in fig. 3, the waste treatment apparatus further comprises: and the gas detection unit 7 is connected with the outlet of the purifier 33, and the detection unit is used for detecting the content of harmful gas at the outlet of the purifier 33.

It should be noted that, when the apparatus is out of order or the purifier 33 is out of order or the purifying effect of the purifier 33 is not good, the treated gas may not reach the standard and a part of the acid gas may not be removed completely. Therefore, by providing the gas detection unit 7 to detect the gas purified by the purifier 33, the safety of the gas discharged into the air is ensured.

As an example, the gas detection unit 7 may be a gas detector. It should be noted that the gas detector is an instrument tool for detecting the gas leakage concentration. The gas detector includes: portable gas detectors, hand-held gas detectors, stationary gas detectors, online gas detectors, and the like. The gas detector that this application embodiment provided can be for fixed gas detection.

In an alternative embodiment, the waste treatment apparatus further comprises: and one end of the circulating treatment pipeline 8 is connected with an outlet of the purifier 33, and the other end of the circulating treatment pipeline 8 is connected with the purifying pipeline 32.

In an alternative embodiment, as shown in fig. 3, the waste treatment apparatus further comprises: a third valve 9, the third valve 9 being located between the gas detection unit 7 and the recycling process line 8.

When a part of the acid gas is detected by the gas detection unit 7, the gas discharge line 7 is closed by controlling the third valve 9, the purge line 32 is opened, and the gas is again introduced into the purge line 32 and then purified by the purifier 33. So, improved gas purification's efficiency, avoided causing environmental pollution because the device breaks down.

The above embodiments are merely illustrative of one or more embodiments of the present invention, and the description is specific and detailed, but not intended to limit the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
