Automatic solid catalytic promoter adding system

Abstract

The application of the invention provides an automatic solid catalytic promoter adding system which comprises a catalyst storage tank, a feeding hopper and a fluidization tank, wherein the top of the catalyst storage tank is provided with a gas-solid separation device; an outlet of the gas-solid separation device runs through the top of the catalyst storage tank and extends outside; the top of the gas-solid separation device is provided with an air outlet; the side wall of the catalyst storage tank is provided with a supplementary feeding hole; one end of the supplementary feeding hole is connected with the gas-solid separation device, and the other end of the supplementary feeding hole is connected with an air source by a feed pipe; the feed pipe connected with the air source is provided with a branch pipe connected with the feeding hopper; the feeding hopper is provided with an inlet, and fresh catalysts can enter the feeding hopper through the inlet; the bottom of the catalyst storage tank is provided with a discharge hole which is connected with the fluidization tank by a pipeline; the catalyst storage tank is supported by a plurality of support legs; weighing sensors are arranged at the bottom parts of the support legs. The adding system is small in size, stable in running, safe, reliable and convenient to operate and needs less conveying air; particularly, due to the design of the fluidization tank, the automatic solid catalytic promoter adding system is high in fluidization efficiency and ensures complete and thorough emptying.

Description

technical field [0001] The invention relates to a novel automatic solid catalyst automatic adding system, which relates to chemical industry, metallurgy, cement ceramics, energy and other industrial categories. Background technique [0002] Many industrial processes (especially chemical processes) require the use of catalysts or additives (hereinafter collectively referred to as catalysts). Catalysts can be divided into liquid catalysts and solid catalysts according to their forms, and solid catalysts can be divided into powders (or powders) according to their forms. ) catalysts and shaped catalysts. Powdered catalysts are generally amorphous, and the particle size is below a few hundred microns, while the size of shaped catalyst particles is above several millimeters, and the shape is spherical, columnar, or honeycomb. Powdered catalysts are most widely used in the petrochemical industry due to their large specific surface area and their uniform mixing with reactants. For...
