Description

Anaerobic separation device for organic solvent suspension

technical field

The utility model relates to an anaerobic separation device for an organic solvent suspension, which belongs to the technical field of anaerobic separation.

Background technique

At present, suction filtration is often used to separate organic solvent suspensions, that is, a flexible hose is extended from the upper part of the container to below the suspension liquid level, and the solvent is pumped out. The slightest inadvertence in this method will extract the powder, resulting in product loss, and the extracted powder will clog the hose, making operation difficult.

Contents of the invention

The purpose of the utility model is to provide an anaerobic separation device for an organic solvent suspension, which uses a filter press method to completely separate the solvent from the solid powder.

The concrete technical scheme of the utility model is as follows:

The top of the reaction kettle of the separation device is connected to the feed pipeline and the nitrogen inlet, one side of the lower cone of the reaction kettle is connected to the filter tube and the organic solvent outlet pipeline in turn, the other side is connected to the hot nitrogen inlet, and the bottom of the reaction kettle is connected to the discharge pipeline. Control valves are connected to the feed line, nitrogen inlet, organic solvent outlet line and hot nitrogen inlet.

This separation device can realize the thorough separation of organic solvent and solid powder, that is, first use nitrogen to press the solvent through the filter tube into the organic solvent outlet pipeline, and then dry the catalyst powder left in the reaction kettle and release it. The separation device has good sealing performance, less product loss, the solvent outlet pipeline is not easy to be blocked, and the operation is simple, which can well solve technical problems such as large product loss, easy blockage of hoses and difficult operation in the prior art.

Detailed ways

The embodiment of the utility model is further described with reference to Fig. 1:

Example:

The separation device includes feed pipeline 1, nitrogen inlet 2, control valve 3, reactor 4, filter tube 5, organic solvent outlet pipeline 6, hot nitrogen inlet 7 and discharge pipeline 8:

The top surface of the reactor 4 is connected to the feed pipeline 1 and the nitrogen inlet 2, one side of the lower conical surface of the reactor 4 is connected to the filter tube 5 and the organic solvent outlet pipeline 6 in sequence, and the other side is connected to the hot nitrogen inlet 7, and the bottom of the reactor 4 is connected to Outlet line 8. A control valve 3 is connected to the feed pipeline 1 , the nitrogen gas inlet 2 , the organic solvent outlet pipeline 6 and the hot nitrogen inlet 7 .

The working process of the separation device is as follows:

Close the hot nitrogen inlet 7 and the discharge pipeline 8, open the nitrogen inlet 2 and the organic solvent outlet pipeline 6, and input nitrogen from the nitrogen inlet 2, so as to maintain a slight positive pressure in the kettle, prevent air from entering and oxidize the product, and avoid static electricity generated by the powder . Under slightly positive pressure conditions, the organic solvent is pressed into the organic solvent outlet pipeline 6 through the filter tube 5 , while the catalyst powder remains in the reactor 4 . Close nitrogen inlet 2 and organic solvent outlet line 6, and open hot nitrogen inlet 7 and outlet line 8. Input hot nitrogen at 60°C from the hot nitrogen inlet 7 to dry the catalyst powder; after it is dried, close the hot nitrogen inlet 7, open the outlet pipeline 8, and release the material.
