Description
One, technical field
The invention belongs to kiln auxiliary equipment, relate in particular to a kind of for SCR board-like catalyst calcination stove detachable fresh air Fast Heating module.
Two, background technology
Atmosphere pollution is one of the most outstanding at present environmental problem in the world, " " 12 " national strategy new industry development regulation " proposes energy-conserving and environment-protective and ranks first of seven great strategy new industries, one of four large mainstay industries are the common prescription of industry restructuring and social equilibrium's sustainable development.Only with regard to environmental protection industry waste gas field, estimate that waste gas pollution control and treatment " 12 " the period market demand capacity is more than 2,300 hundred million yuan, wherein thermal power plant's denitration market demand is 1,000 hundred million, and flue gas " denitrating catalyst " is clearly listed in one of the core environment protection novel and product that support China's strategy new industry development.
Board-like SCR denitration is environmental protection rising industry, perfect along with national environmental protection policy, and its market potential is huge, and this technology is first grown up by Japan at the 70's Mos of 20th century and the beginning of the eighties, is promoted in Europe and the U.S. rapidly thereafter.Board-like SCR denitration main component generally comprises nano-TiO
2, V
2o
5and WO
3.Shared by these three kinds of compositions, catalyst ratio is more than 95 ﹪, and pug or powder raw material are mainly coated on stainless steel expansion web by board-like Catalyst Production after batch mixing, kneading, through section, shaping, vanning, is finished product finally by the calcining of continuous calcining stove.The board-like catalyst of SCR denitration is mainly used in the denitration engineering of the industry flue gases such as electric power, metallurgy, building materials.Plate-type denitration catalyst complete series product has high denitration efficiency, high performance of anti-blockage, high resistance flying dust erosion performance, low SO
2conversion ratio, low NH
3the excellent specific properties such as escapement ratio, low pressure loss and good anti-poisoning capability, are widely used in the denitrating flue gas environment of high dust.Can there is slight jitter when flue gas is by catalyst in the veneer of flat catalyst, can prevent thin ash from piling up on a catalyst.Stainless steel aperture plate skeleton structure, antiwear property is strong, more resistance to flying dust corrosion.The supplementary in time and Fast Heating of fresh air is one of key factor ensureing product quality, and technology often can not meet manufacturing technique requirent to the timely heating of supplementary fresh air at present, brings certain mass defect to product.
Three, summary of the invention
The object of the invention is the technology of the present invention for prior art Problems existing, by setting up detachable heating module, can in limited space Modulating Power density, effectively improve the efficiency of heating surface of fresh air in air channel, decrease the energy consumption of unit product, improving product, to burn till quality high.
Technical scheme of the present invention is: it is by circulating fan, circulation air path, the part such as furnace wall and heating module is formed, described heating module is by shell, draw ring, binding post, porcelain bushing shell, electrothermal tube and heat insulation fiber composition, shell is the cuboid that corrosion resistant plate is welded into, inside fill out heat insulation fiber, and in the both sides of heat insulation fiber uniform three layers of porcelain bushing shell up and down, three layers of porcelain bushing shell worn respectively by three electrothermal tube two ends lead-in wires, the binding post of electrothermal tube is made to expose the antetheca of shell, draw ring is arranged in the middle of housing front plate, electrothermal tube is in bending helical form, resistance wire sleeve pipe is that nichrome material makes.This heating module is arranged in the middle and lower part reserving installation hole of furnace wall, and electrothermal tube is in circulation air path.
The invention has the beneficial effects as follows: due to the detachable heating module setting up a kind of Fast Heating fresh air in calcining furnace is produced, it is by changing electric heating cover tube shape, Modulating Power density in the space making it limited, effectively can improve the efficiency of heating surface of fresh air in air channel, extend the service life of heating module, decrease the energy consumption of unit product, and product to burn till quality high, there is application value widely.
Below in conjunction with accompanying drawing, the invention will be further described.
