The technical field is as follows:

the invention relates to the technical field of treatment of viscous solid-liquid mixtures, in particular to a device and a method for separating solid-liquid mixtures.

Background art:

for a solid-liquid mixture containing viscous liquid, the traditional separation method (such as filtration, centrifugation and the like) is difficult to completely separate the solid from the liquid, so that the solid material is not easy to efficiently and cleanly recover.

The invention content is as follows:

aiming at the defects of the existing separation method, the invention mainly provides a device and a method for separating viscous solid-liquid mixture.

In order to achieve the purpose, the invention adopts the following technical scheme:

the invention provides a device for separating viscous solid-liquid mixture, which comprises a solid-liquid mixture filling system and a liquid collecting system, wherein the solid-liquid mixture filling system is connected with the liquid collecting system through a pipeline; one end of the solid-liquid mixture filling system is provided with a gas inlet, the other end of the solid-liquid mixture filling system is connected with a liquid collecting system through a pipeline, and the other end of the liquid collecting system is provided with a gas outlet; a filling area of the solid-liquid mixture filling system is provided with a temperature control device, and the filling area is positioned in a constant temperature area in the solid-liquid mixture filling system and is provided with a fixing piece for fixing the solid-liquid mixture; and a heat preservation device is arranged at the position of the pipeline between the solid-liquid mixture filling system and the liquid collecting system to control the temperature of the pipeline.

Preferably, the temperature control device is a temperature control box provided with a thermocouple.

Preferably, the fixing part is made of quartz wool or an orifice plate, and the orifice plate is made of ceramic, glass or quartz. Generally, the quartz wool can be used for fixation in the invention, because the air flow rate is not large, the quartz wool and the solid-liquid mixture are not blown.

The material of the pipeline between the solid-liquid mixture filling system and the liquid collecting system is required to be high temperature resistant, not easy to corrode, the inner wall is smooth, and the separated viscous liquid is not easy to adhere to prevent blocking the pipeline. Therefore, a copper pipe or a stainless steel pipe is preferable, and a stainless steel pipe is more preferable. The pipeline is provided with a heat preservation device to ensure that the liquid in the solid-liquid mixture is not liquefied again due to temperature reduction after being gasified in the solid-liquid mixture filling system.

Preferably, the heat preservation device is a heating belt which wraps the outer wall of the pipeline and controls the temperature of the pipeline.

Preferably, the heat preservation device is a heat preservation box which covers the outlet of the pipeline and realizes temperature control.

Preferably, the gas inlet is arranged at the top of the solid-liquid mixture filling system, the pipeline is connected with the bottom of the solid-liquid mixture filling system and the top of the liquid collecting system, and the gas outlet is arranged at the side or the top of the liquid collecting system.

Preferably, the liquid collection system is made of a material which is easy to conduct heat, such as glass, stainless steel and the like, so that gas entering the liquid collection system can be liquefied as soon as possible.

Preferably, the apparatus further comprises cooling means for cooling the liquid collection system. The cooling device can be a glass bottle, and circulating cooling water is introduced into one layer of the outer surface of the glass bottle.

The invention provides a method for separating viscous solid-liquid mixture by using the device, which comprises the following steps:

(1) fixing a viscous solid-liquid mixture in a filling area of a solid-liquid mixture filling system;

(2) the temperature of a constant temperature area in a solid-liquid mixture filling system is controlled to be higher than the boiling point temperature of liquid in the viscous solid-liquid mixture by a temperature control device, the temperature of a pipeline between the solid-liquid mixture filling system and a liquid collecting system is controlled to be higher than the boiling point temperature of the liquid in the viscous solid-liquid mixture by a heat preservation device, meanwhile, inert gas is continuously introduced from a gas inlet of the solid-liquid mixture filling system, the liquid in the viscous solid-liquid mixture is gasified in the solid-liquid mixture filling system and is brought into the liquid collecting system by the inert gas, the gasified liquid is liquefied again in the liquid collecting system, and the inert gas is discharged from a gas outlet.

Preferably, the method further comprises: and after the separation is finished, cooling the solid in the solid-liquid mixture filling system under the protection of inert atmosphere. Because some organic matters are flammable in a high-temperature oxygen atmosphere, the inert atmosphere can prevent the organic matters from being burnt; in addition, special solids, such as catalysts to be recovered after reaction, are prone to severe oxidation and severe heat release when exposed to oxidative atmosphere such as oxygen. Therefore, the temperature reduction in the inert atmosphere helps to avoid the above-mentioned situation, and in some cases, the passivation process can be even supplemented as required.

Preferably, the temperature of the constant temperature zone in the solid-liquid mixture charging system and the temperature of the pipe between the solid-liquid mixture charging system and the liquid collecting system are controlled to be: at least 5 ℃ higher than the boiling point of the liquid in the viscous solid-liquid mixture, and if the temperature is set to be lower, the viscous liquid on the surface of the solid can not be removed efficiently. More preferably, the temperature is even 5-30 c above the boiling point of the liquid in the viscous solid-liquid mixture.

Preferably, the inert gas is N₂Inert atmosphere of Ar, He, etc., preferably N₂Or Ar.

Preferably, the space velocity of the inert gas is 5000-6500 mL/g.h; the treatment time is 10-12 h. The reason is that the space velocity is too small, the time is too short, the viscous liquid on the solid surface can not be removed well, and the space velocity range can remove the liquid, and meanwhile, the treatment time is short, the economy is high, and the method is more suitable for industrial production.

The device for separating viscous solid-liquid mixture and the treatment process provided by the invention have the advantages that:

the invention can realize effective separation of viscous solid-liquid mixture by adopting a simple treatment device. Meanwhile, the equipment is safe and efficient to operate.
