Automatic air renewal system for SCR plate type catalyst calcining furnace

Abstract

The invention discloses an automatic air renewal system for an SCR plate type catalyst calcining furnace. The automatic air renewal system for the SCR plate type catalyst calcining furnace solves the problem that product defects such as unqualified product calcination quality or low activity are prone to occurring in the prior art. The automatic air renewal system for the SCR plate type catalyst calcining furnace is characterized in that an exhaust gas exhausting device is composed of an exhaust branch pipe (10), an exhaust main pipe (2) and an exhausted flow detection controller (4) which are arranged on the top of the calcining furnace (1); a fresh air supplementary device is composed of an air supplementary branch pipe (9), a fresh air main pipe (3) and an air supplementary flow detection controller (5) which are arranged on one side of the furnace wall; meanwhile a temperature detector (7) and a pressure detector (8) are arranged in the calcining furnace (1), and the temperature detector (7) and the pressure detector (8) are connected with an industrial computer network through circuits. The automatic air renewal system for the SCR plate type catalyst calcining furnace has the advantages that the design is reasonable, the operation is convenient, and the air supplementary and the air exhaust can be carried out effectively and automatically in a balanced mode. The produced SCR plate type denitration catalyst is stable and high in product quality, the product quality is improved, and the automatic air renewal system is worthy of popularization.

Description

1. Technical field [0001] The invention belongs to kiln auxiliary facilities, in particular to an automatic ventilation system 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 clear...
