Embodiment Construction

[0013] Such as figure 1 As shown, the detachable fast heating module 3 is installed in the installation hole reserved in the middle and lower part of the furnace wall 4 of the calciner, so that the electric heating tube 9 is in the circulation air duct 2 of the calciner, and the supplemented fresh air plays the role of the circulation fan 1 The bottom is sent from top to bottom and installed in the circulating air duct 2. The fresh cold air and the surface of the resistance wire sleeve made of nickel-chromium alloy material of the electric heating tube 9 are continuously heat-exchanged, so that the air can quickly heat up and meet the requirements of product production. Process requirements to ensure product firing quality. The detachable rapid heating calciner for the production of SCR plate catalyst is composed of a shell 5, a pull ring 6, a terminal post 7, a porcelain sleeve 8, an electric heating tube 9 and a heat insulating fiber 10, etc., and the shell 5 is a stainless ...

Abstract

The invention discloses a detachable type quick heating calcining furnace for SCR (Selective Catalytic Reduction) plate type catalyst production, and aims to solve the problem that the calcining quality of a product is affected by a fact that supplemented fresh air cannot be heated in time in the prior art. The detachable type quick heating calcining furnace is characterized in that a heating module (3) consists of a shell (5), a pull ring (6), wiring posts (7), ceramic sleeves (8), electrothermal pipes (9) and heat isolation fibers (10), wherein the shell (5) is a cuboid welded by a stainless steel plate and is filled with the heat isolation fibers (10); lead wires at the two ends of each of the three electrothermal pipes (9) respectively penetrate through the three ceramic sleeves (8) of the heat isolation fiber layers; the heating module (3) is arranged in a mounting hole reserved in the middle lower part of a furnace wall (4), so that the electrothermal pipes (9) are positioned in a circulating air duct (2). The detachable type quick heating calcining furnace has the advantages of scientific combination, simplicity in manufacturing, convenience in mounting, quickness in heating and the like and has wide popularization and application value.

Description

1. Technical field [0001] The invention belongs to kiln auxiliary facilities, in particular to a detachable fresh air rapid heating module 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 cataly...
