Shell of cyclone separator for producing white black carbon

Abstract

The invention discloses a shell of a cyclone separator for producing white black carbon. The shell comprises an outer layer shell and an inner layer shell, wherein N minitype holes are formed in the inner layer shell, the hole diameter of each minitype hole is 60-130mu m, and the distance between every two adjacent minitype holes ranges from 60mu m to 300mu m, wherein N is an integer which is more than 100. In the working process of the cyclone separator, white black carbon powder is subjected to great centrifugal force action at the inner layer shell, the white black carbon powder is encountered with the inner layer shell provided with the minitype holes each of which the hole diameter is 60-130mu m and every two of which have the distance of 60mu m-300mu m, which is similar to be encountered with a slicer with the cutting role, large powder particles are cut into small powder particles, the energy at the shell can be fully utilized, and the particle diameter of the obtained white black carbon can be reduced by more than 20mu m on average under the condition of not changing other techniques.

Description

technical field [0001] The invention relates to the technical field of chemical production equipment, in particular to a housing of a cyclone separator used for producing white carbon black. Background technique [0002] Silica is the general term for white powdered amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica, ultrafine silica gel and silica aerogel, including powder Synthetic aluminum silicate and calcium silicate, etc., particle diameter is an important quality standard of white carbon black. [0003] In the production process of white carbon black, white carbon black comes out of the plate and frame filter press into a paste shape, which has no fluidity, and needs to go through processes such as beating, rotary drying, and cyclone separation (such as figure 1 Shown) to obtain powder products, among them, the cyclone separator is an important separation equipment. [0004] In the existing process flow, the main func...

AI Technical Summary

Problems solved by technology

[0004] In the existing process flow, the main function of the cyclone separator is to separate the dried silica according to the particle size, and the silica with a larger particle size falls into the cyclone under the action of centrifugal force and gravity at the shell. At the bottom of the separator, white carbon black with a particle diameter of 80-150um enters the subsequent production process from the return pipe of the cyclone separator under the action of the secondary vortex; in this process, the energy at the shell of the cyclone separator has no Take advantage of
