Background

Along with the development of industrialization, the pollution of waste gas is more and more serious. And the components of the exhaust gas are more and more complex, especially the exhaust gas contains various complex and high-concentration organic exhaust gases, the components of the organic exhaust gases (VOCs) are complex, some are important sources causing greenhouse effect, some are important precursors forming photochemical smog and PM2.5, and some even have strong carcinogenicity, mutagenicity and teratogenicity. The organic waste gas usually contains harmful gases such as benzene, carbon monoxide, polycyclic aromatic hydrocarbon and the like due to thin combustible components, is very difficult to treat and is often directly exhausted, which not only causes a large amount of energy waste, but also causes environmental pollution and aggravation of greenhouse effect. Therefore, the development of a method for treating organic waste gas with high efficiency and low energy consumption is one of important means for relieving a series of energy and environment problems in China.

At present, although equipment for treating organic gas through photolysis exists, the equipment is usually separated from dust treatment, and has long pipelines and large occupied space.

Detailed Description

An embodiment of the integrated plant dust and voc apparatus of the present invention will be further described with reference to fig. 1 to 4.

In the description of the present invention, it should be noted that, for the terms of orientation, such as "central", "lateral (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate that the orientation and positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of the present invention.

Furthermore, if the terms "first" and "second" are used for descriptive purposes only, they are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features. Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features, and in the description of the invention, "a number" or "a number" means two or more unless explicitly specified otherwise.

The utility model provides an integration is handled workshop dust and volatile organic gas's equipment, includes a vertical casing 1 of arranging, and air inlet 11 is seted up to casing 1 below, and air outlet 12 is seted up to the top shower 2, UV photodissociation fluorescent tube 3, secondary shower 4 and defroster 5 have set gradually from bottom to top in the casing 1.

As shown in fig. 1, the pre-shower 2 and the secondary shower 4 are both provided with a plurality of nozzles through which dispersed water is ejected.

Gas (waste gas) that produces in the workshop gets into in the casing 1 through air inlet 11, wet make it subside to casing 1 bottom with most dust in the shower with gas, when gas reachs UV photodissociation fluorescent tube 3 department, UV photodissociation fluorescent tube 3 is to the organic matter photodissociation in the gas, 4 spun water of secondary shower continue moist remaining dust and make the dust subside to casing 1 bottom, 4 spun water of secondary shower will wash UV photodissociation fluorescent tube 3 simultaneously, make UV photodissociation fluorescent tube 3 keep good performance all the time, avoid surface covering debris and shading, moisture in the defroster 5 to gas is held back, and with water recycle, make at the bottom of the 12 combustion gas water content of air outlet.

The preferred defroster of this embodiment is provided with adsorption equipment between 5 to air outlet 12, and adsorption equipment is waterproof honeycomb active carbon 6, and waterproof honeycomb active carbon 6 can adsorb remaining volatile organic gas, makes the combustion gas purify more thoroughly.

The demister 5 preferably includes a plurality of corrugated plates 51 arranged in sequence, the corrugated plates 51 are gradually lowered from the middle to the two ends, as shown in fig. 3 and 4, the corrugated plates 51 are arched in the front view direction, it is needless to say that the corrugated plates 51 may be entirely triangular, that is, the middle portion is higher and is in a linear state in the direction of the two ends, as shown in fig. 2, the plurality of corrugated plates 51 are fixed together by fixing plates 52 and are entirely formed.

As shown in fig. 1, when the two ends of the corrugated plate 51 are close to the inner wall of the housing 1, when gas is purified, when the gas containing water mist reaches the corrugated plate 51 of the demister 5, the water mist is intercepted by the corrugated plate 51, the water mist gradually forms liquid drops on the corrugated plate 51, the water mist can flow to the two ends along the arc-shaped edges or the arc-shaped bottom edges on the corrugated plate 51, and large liquid drops are formed at the lowest positions of the two ends of the corrugated plate 51 and drop along the inner wall of the housing 1, so that the dropping position of the liquid drops formed on the demister 5 is controllable, and the possibility of dropping at any position of the corrugated plate 51 is avoided.

If the droplets fall from the middle position or other positions of the corrugated plate 51 to the UV photolysis lamp tube 3, as in the prior art, the corrugated plate 51 is entirely horizontal, the water mist forms droplets on the corrugated plate 51 and flows directly downward, and cannot move laterally, and then the droplets directly fall from the bottom end of the corrugated plate 51 when forming the droplets, especially when the bottom end of the corrugated plate 51 has a partially lower position (the corrugated plate 51 is not flat enough), a large amount of droplets will condense and fall there, the drops contain impurities, and long-term dripping at the same position of the UV photolysis lamp tube 3 causes contamination or premature damage of the UV photolysis lamp tube 3.

In the preferred embodiment, the bottom of the corrugated plate 51 is provided with a water guide plate 511, a water guide groove 512 is formed between the water guide plate 511 and the corrugated plate 51, the water guide plate 511 is in a lower arc shape as shown in fig. 2 and 3, part of the water mist is gathered in the water guide groove 512 when flowing to the bottom end of the corrugated plate 51, and flows to the inner wall of the shell 1 along the water guide groove 512, and particularly when the equipment is influenced by vibration during operation, the water droplets can be ensured to flow to both ends of the corrugated plate 51 to the inner wall of the shell 1.

In the embodiment, the water guide plates 511 of two adjacent corrugated plates 51 are staggered with each other in the vertical direction, as shown in fig. 2, the staggered water guide plates 511 can ensure the cross section of the wind channel between two adjacent corrugated plates 51, and prevent the two water guide plates 511 from blocking the flow of the gas at the same position.

In this embodiment, an inner water guide flange 13 is disposed in the casing 1 corresponding to the lower portion of the demister 5, a water guide pipe 7 is disposed on the casing 1 corresponding to the inner water guide flange 13, the water guide pipe 7 extends out of the casing 1, generally, all the corrugated plates 51 are sequentially arranged to form the demister 5, the inner water guide flange 13 contacts with two ends of all the corrugated plates 51 (a circle can be disposed on the inner wall of the casing 1), so that liquid drops flowing down on the corrugated plates 51 are collected on the inner water guide flange 13 in a centralized manner and led out along the water guide pipe 7, the water quality led out by the water guide pipe 7 is better than that at the bottom of the casing 1, and the water can be filtered or precipitated for reuse, and the processing time is short; of course, the water guiding pipe 7 may have one end connected to the water guiding plate 511 and the other end extending to the bottom of the case 1, as shown by the dotted line in fig. 1.
