Embodiment Construction

[0039] Combine below Figure 3 to Figure 9 , the present invention is further described:

[0040] Such as image 3 As shown, a conical gas distributor includes a plurality of sieve holes 12, and a wear-resistant protrusion 2 is respectively arranged in the plurality of sieve holes 12, and a solid body is arranged at the center of the wear-resistant protrusion 2 Particle passage holes 26 . Since a wear-resistant protrusion 2 is respectively provided in the plurality of screen holes 12 of the gas distributor, when the silicon powder under high temperature and high pressure enters the gas distributor, it will directly act on the wear-resistant protrusion instead of directly acting on the gas. At the periphery of the sieve hole of the distributor, the silicon powder under high temperature and high pressure will wear off the wear-resistant protrusions on the periphery of the sieve hole first, thus prolonging the service life of the gas distributor and improving the working effici...

Abstract

The invention relates to a conical gas distributor. The conical gas distributor comprises a plurality of sieve meshes, wherein a wear-resistant bump is arranged in each sieve mesh; the central part of the wear-resistant bump is provided with a solid particle passing hole; each wear-resistant bump comprises a wear-resistant bump body, an upper fixture and a lower fixture; the length of the wear-resistant bump body is more than the thickness of the wall of the gas distributor; and after the wear-resistant bump body is inserted into the sieve mesh, the upper fixture and the lower fixture are fixedly connected with the wall of the gas distributor by the upper end and the lower end of the wear-resistant bump body through a horizontal fixing device and a vertical fixing device respectively. Because the wear-resistant bump is fixed on the wall of the gas distributor through the horizontal fixing device and the vertical fixing device, the wear-resistant bump can bear the collision of silicon powder which moves at a high speed without separating or loosening components at high temperature and under high pressure by mutually matching the two fixing devices, so that the service life of the gas distributor is prolonged.

Description

technical field [0001] The invention relates to a gas distributor suitable for the field of chemical industry, in particular to a gas distributor in a fluidized bed. 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 with 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 pass through the multiple meshes 12 on the gas distributor 11 and enter the finger-shaped heat exchange tube for chemical reaction. [0004] However, powdered silicon fume carries a large amount of impact energy und...
