Diphase separating element, and separator, reactor and adsorption equipment of containing the element

Abstract

A two-phase separating unit and the two-phase separator, the fixed-bed reactor for catalytic reaction and the gas adsorbing apparatus, all of which contains said two-phase separating, are disclosed. Said two-phase separating unit is composed of two or more perforated barrels to form one or more annular cavities, in which the solid particles are filled to form the inrregular gap channels.

Description

technical field [0001] The invention relates to environmental protection and chemical equipment, especially a two-phase separation unit cylinder and a two-phase separation device containing the unit cylinder, which are used for two-phase mixing of gas and solid, gas and liquid, gas and liquid-solid mixture, liquid and solid Physical separation of media, and a fixed-bed reactor comprising the unit cylinder structure for catalytic reactions; a device comprising the unit cylinder structure for gas absorption or adsorption; a non-annular cavity-type two-phase separate unit. Background technique [0002] In the prior art, the physical separation technology of gas and solid, gas and liquid or liquid and solid two-phase mixed media is often used as a cloth bag filter or a wire mesh filter, and the corresponding filter medium is a fiber bag or Metal mesh. Although there are many kinds of fiber bags, they are basically only used for gas-solid separation due to the characteristics o...

AI Technical Summary

Problems solved by technology

Due to the characteristics of its material, the fiber bag has poor temperature resistance, and the working temperature is generally below 220°C, and the maximum does not exceed 350°C; the relative humidity content of the gas is also required to be low during operation, and the one-phase material to be filtered is required to be cohesive. Low and good dispersion, otherwise the filter cloth of the fiber bag will be blocked; the filter cloth is often not easy to clean and regenerate, and it is not easy to complete, and the replacement of the fiber bag is not convenient, and the replacement can only be carried out under parking

There are also problems with wire mesh. Because of the material, structure and thermal expansion, the working temperature is also limited, and it is easy to block. The cleaning and regeneration has the disadvantages of inconvenience, low update degree, inconvenient replacement, and high cost. It must be done while parking, and it is impossible to do it online or while driving

[0003] The fixed-bed reactor used for catalytic reaction in the prior art only has a single function of catalytic reaction, and requires a high degree of cleanliness of the medium, so as to prevent impurities from adhering to the surface of the catalyst and affecting its activity.

Therefore, it is not used as a two-phase separation function device

In addition, the particle size of the catalyst in the catalytic fixed bed is required to be coarse to reduce leakage and maintain fluid channels, but the activity is affected

It is also inconvenient to replace the invalid catalyst, and online replacement cannot be realized

[0004] In the prior art equipment used for gas absorption or adsorption, the particle size of the absorbent or adsorbent is required to be coarse, the replacement of the absorbent or adsorbent is inconvenient, and online replacement cannot be realized
