Air distribution system for SCR plate-type catalyst continuous calcining furnace

Abstract

The invention discloses an air distribution system for an SCR plate-type catalyst continuous calcining furnace. The air distribution system solves the problem that in the prior art, the product quality is affected because hot air enters calcinated products unevenly. The air distribution system is characterized in that a sieve plate (4) used for carrying a catalyst product (6) is arranged at the bottom of a product loading box (7), and an air inlet duct (11) is arranged between the sieve plate (4) and a trolley (5); the two sides of the air inlet duct (11) are each provided with an upper air distribution plate (3) and a lower air distribution plate (3), and the air distribution plates (3) divide the air inlet duct (11) into three branch air ducts, so that circulating hot air enters all section gaps of the catalyst product (6) evenly; air inlets (2) on the two sides of the air inlet duct (11) are communicated with air outlets (1) formed in the lower portion of a circulating air duct (8) in the calcining furnace (9). The air distribution system has the advantages of being reasonable in structure, easy to manufacture, convenient to install, good in uniform distribution and the like, and can fully meet the technological requirements for product calcination and guarantee the quality of the catalyst product.

Description

1. Technical field [0001] The invention belongs to kiln auxiliary facilities, in particular to an air distribution device for an SCR plate catalyst calciner. 2. Background technology [0002] Air pollution is one of the most prominent environmental problems in the world at present. The "Twelfth Five-Year Plan" National Strategic Emerging Industry Development Regulations proposes that energy conservation and environmental protection rank first among the seven strategic emerging industries and one of the four pillar industries. The common requirement of industrial restructuring and sustainable development of social balance. As far as the waste gas field of the environmental protection industry is concerned, it is estimated that the market demand for waste gas treatment during the "12th Five-Year Plan" period will exceed 230 billion yuan, of which the market demand for denitration in thermal power plants is 100 billion yuan, and the flue gas "denitration catalyst" is clearly li...

AI Technical Summary

Problems solved by technology

[0004] Since the SCR plate denitrification catalyst is calcined vertically, air stratification can be avoided, but the hot air circulation in the entire circulation chamber has a 180° turn in the entire flow field, and the hot air after the turn enters the catalyst product unevenly, and some positions have a large amount of hot air , In some places, the amount of hot air is small, and it is often easy to burn the catalyst plate, which not only greatly affects the product quality, but also produces a lot of waste products
