Embodiment 1

[0061] Adopt the described gas-solid separation equipment of above-mentioned more preferred embodiment to implement gas-solid separation process, wherein, cyclone separator has two feeding ports 3 (such as image 3 shown), the two feed ports 3 are respectively located on both sides of the cylinder 2 close to the top. The gas-solid mixture is a gas-solid mixture of gasoline-adsorbed desulfurization adsorbent solid particles with an average particle size of 65.0 microns and air. The inlet linear velocity of the gas-solid mixture entering the feed port 3 is 3m / s. Collect solid particle by dipleg 7, know by detection and calculation, the recovery rate of solid particle and average particle diameter are as shown in table 1; The results are shown in Table 2.

Abstract

The invention relates to a gas-solid separation device, which comprises a cyclone separator and a filtering part. The cyclone separator comprises a cylindrical shell and a hollow circle bench with an upward and large opening, the opening at the lower end of the cylindrical shell is superposed with the opening at the upper end of the hollow circle bench, an air exhaust opening is provided at the top of the cylindrical shell, wherein the filtering part is positioned in the cyclone separator, the filtering part comprises an inner side filter layer and an outboard filter layer, the inner side filter layer and the outboard filter layer are connected at bottom to form a sealing end, the inner side filter layer is connected at the top to form the sealing end, and the top of the outboard filter layer and the air exhaust opening are connected. The gas-solid separation device is used for gas-solid separation to obtain the high solid particle yield, solid particle wearing is reduced, and the obstruction of the filtering part can be alleviated.

Description

technical field [0001] The invention relates to a gas-solid separation device. Background technique [0002] Gas and solid separation equipment are widely used in chemical industry, metallurgy, pharmaceutical, environmental protection and other industries. Commonly used gas and solid separation equipment include cyclone separators and filters. [0003] The cyclone separator uses the centrifugal force generated when the gas-solid phase material with a certain flow rate rotates to separate solid particles from the gas-solid phase material to achieve the purpose of gas-solid separation. However, when the cyclone separator separates very fine particles or lighter particles with a relatively small density, these particles will be discharged from the exhaust pipe with the airflow, so that the separation efficiency of the cyclone separator drops sharply. In the field of petrochemical industry, when purifying flammable and toxic gases that cannot be discharged, separating fine part...
