Large stepping type rotating pulse desuter

Abstract

A large stepping type rotating pulse desuter is composed of an upper barrel (with an air outlet), a volute, a middle barrel, an ash hopper, a support, a top guardrail, a compressed air inlet pipe, an air bag, a pulse valve, a stepping motor, a speed shifting mechanism, spray-blow pipes, a top cover, a tube nest, a filter bag assembly, a guide grid and an ash discharging valve. The large stepping type rotating pulse desuter is of a round structure and is simple in structure, convenient to construct and high in compression strength. A filter bag is a round special denting-preventing device. The tube nest is specially arranged. Filter area of one deduster reaches 2540 square meters, and one deduster is only provided with one pulse valve, two to three spray-blow pipes and one air bag arranged in an air purifying chamber and rotating to be balanced. An air inlet is arranged on the upper portion of the middle barrel and is a tangential cyclone inlet. A module type structure is adopted so that processing and transporting are facilitated. A plurality of large stepping type rotating pulse desuters can form a super large pulse desuter which has the advantages of being low in investment and operation expanse and wide in adaptive range.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a large-scale stepping rotary pulse dust collector, which is mainly used in flue gas treatment of power station boilers, cement rotary kilns, large ferroalloy electric furnaces, and calcium carbide furnaces. [0002] Background technique: [0003] In our country, with the advancement of science and technology and the adjustment of national industrial policies, various industrial furnaces are developing towards large-scale and modernization. direction development. In order to meet the market demand, my country has introduced the world's most advanced low-pressure rotary pulse bag filter from the French Lurgi company. Each filter bag bundle can arrange 1156 filter bags with a length of 8m and a maximum filter area of ​​3700m 2 .It has been successfully applied in our country. However, since the filter bag used in this equipment is flat and round, it must be equ...

AI Technical Summary

Problems solved by technology

However, since the filter bag used in this equipment is flat and round, it must be equipped with a flat round filter bag cage. The pulse valve used is a large pulse valve of 8 inches, which cannot be produced in China and needs to be imported.

And expensive, difficult to achieve localization
