Wear-resistant gas distributor

Abstract

The invention relates to a wear-resistant gas distributor. The wear-resistant gas distributor comprises a plurality of sieve holes, wherein each of the plurality of sieve holes is provided with a wear-resistant bulge; a solid particle through hole is formed in the center of each wear-resistant bulge; each wear-resistant bulge comprises a wear-resistant bulge main body member, an upper fixing member and a lower fixing member; the length of the wear-resistant bulge main body member is more than the thickness of the wall of a gas distributor; after the wear-resistant bulge main body members are inserted into the sieve holes, the upper fixing members and the lower fixing members are fixedly connected to the wall of the gas distributor by a fixing device through the upper and lower end parts of the wear-resistant bulge main body members. As the wear-resistant bulge main body members, the upper fixing members and / or the lower fixing members are fixedly connected to the wall of the gas distributor through fixed screws, fixed screw mounting parts are located at two sides of the upper fixing member and / or the lower fixing member instead of a place at which solid particles are easily or powerfully worn, and thus the service life of the fixed screw is prolonged, and the wear-resistant bulges on the gas distributor are easily dismounted and replaced.

Description

technical field [0001] The application date of the present invention is October 26, 2010, the application number is: 201010527036.7, and the divisional application of the invention patent application named "a wear-resistant gas distributor". The invention relates to a gas distributor suitable for the field of chemical industry, in particular to a wear-resistant gas distributor. Background technique [0002] A large number of gas distributors are used in the chemical industry, including flat, spherical and conical. One of its main functions is to allow the reactants to be evenly distributed, to speed up the reaction efficiency and shorten the reaction cycle. [0003] For example, fluidized beds in silicone manufacturing require the use of conical gas distributors. Such as figure 1 and figure 2 As shown, a plurality of mesh holes 12 are provided on the gas distributor 11 . After the silicon powder enters the high-temperature and high-pressure fluidized bed, it needs to p...

AI Technical Summary

Problems solved by technology

[0006] The invention designs a wear-resistant gas distributor, which solves the technical problems: (1) the gas distributor used in the existing fluidized bed has a short service life, and also seriously affects the production efficiency; (2) the existing gas Frequent replacement of distributors will cause serious waste of resources
