Abstract
The invention discloses a product effective loading space for an SCR plate-type catalyst continuous vertical calcining furnace. The product effective loading space is used for solving the problem of the prior art that hot air field in a hearth is uneven. The product effective loading space is characterized in that inner cavity separating plates (5) are arranged on the two sides and at the top of a hearth of the calcining furnace (7); a circulating fan (1) is arranged at the top; a product loading box (4) is arranged on a trolley (8); SCR plate-type catalyst products (6) are uniformly arranged in the product loading box (4). The product effective loading space has the advantages of reasonable structure, convenience in mounting, uniform temperature field, high yield, high product quality and high popularization and application values.
Description
One, technical field
The invention belongs to kiln auxiliary equipment, relate in particular to a kind of product efficient loading space for SCR board-like catalyst vertical continuous calcining furnace.
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 late 1970s 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.
Catalyst burns till the activity that most critical is it, board-like catalyst in calcination process particularly the calcining heat of the constant temperature zone of high temperature be even more important, it concerns catalyst and survives, temperature controls very strict, exceed temperature in prescribed limit and all can make catalyst loss of activity, so the calcining of the foundation of a calcining furnace inner chamber homogeneous temperature field to the board-like catalyst of SCR is most important, be an important topic for denitrating catalyst is produced.
Three, summary of the invention
The object of the invention is the technology of the present invention for prior art Problems existing, design and produce the airtight air torus of calcining furnace, make calcining furnace inner chamber be a homogeneous temperature field, allow the air after heating ceaselessly flow along this torus and guarantee the quality of calcination product.
Technical scheme of the present invention is: it is made up of the part such as calcining furnace and chassis, is provided with inner chamber dividing plate, and forms air torus between inboard wall of burner hearth, and be provided with circulating fan in the burner hearth both sides of calcining furnace and top in top spacer.Chassis is provided with product carrying case, and this product carrying case top is provided with suction opeing, and arrange air inlet duct between bottom with chassis and communicate with air torus in burner hearth, the board-like catalyst prod of SCR is evenly placed in product carrying case.
The invention has the beneficial effects as follows: owing to not being directly heat product in furnace chamber, but design an air torus on furnace body; Product is evenly placed in the carrying case on chassis, allow and add hot-air and ceaselessly back and forth flow along this sealing and circulating chamber, heat is constantly passed to catalyst prod and carry out calcining heating, thus ensure that catalyst calcination uniform temperature fields, greatly reduce the temperature difference in stove, improve catalyst prod quality.
Below in conjunction with accompanying drawing, the invention will be further described.
Four, accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present invention.
In figure: 1 is circulating fan, 2 is air torus, and 3 is suction opeing, and 4 is product carrying case, and 5 is inner chamber dividing plate, and 6 is the board-like catalyst prod of SCR, and 7 is calcining furnace, and 8 is chassis, and 9 is air inlet duct.
Five, detailed description of the invention
As shown in Figure 1, product efficient loading space for SCR board-like catalyst vertical continuous calcining furnace is made up of parts such as calcining furnace 7 and chassis 8, inner chamber dividing plate 5 is provided with in the burner hearth both sides of calcining furnace 7 and top, and form air torus 2 between inboard wall of burner hearth, and in top spacer, be provided with circulating fan 1.Chassis 8 is provided with product carrying case 4, and this product carrying case 4 top is provided with suction opeing 3, and arrange air inlet duct 9 between bottom with chassis 8 and communicate with air torus 2 in burner hearth, SCR is board-like, and catalyst prod 6 is evenly placed in product carrying case 4.An airtight air circulation space is formed between air torus 2 like this in burner hearth, the air inlet duct 9 of product carrying case 4 and suction opeing 3 and circulating fan 1.When implementing of the present invention, chassis 8 carries the board-like catalyst prod 6 of SCR and enters calcining in calcining furnace 7, heat is from by the air heated, heating process is not that hot-air is directly blown into heating products in stove, but by the airtight air torus of custom-designed calcining furnace, blower fan power is relied on ceaselessly to move in circles in the airtight air torus jointly formed at air torus and product carrying case by the air that heats, continuously even heat is passed to product, meet the technological requirement of product calcining.Due to the board-like catalyst prod of SCR, the air after heating must be allowed along the flowing of product gap, could qualified products be calcined.And air flowing is taken a shortcut, if do not arrange product load chamber of the present invention around product, hot-air can rise beyond product surrounding iron plate, because the flow resistance that hot-air is flowing in product surrounding can be more much smaller than entering the resistance flowed in product.Therefore except leaving product thermal expansion gap, product is close to carrying case inner surface as far as possible, allows thermal air current to product, reduces bypass, effectively heating products, effectively can reduce energy consumption simultaneously.Sealing torus of the present invention can not only allow thermal air current to Li Pin district heating products effectively, and due to air press certain speed flowing, can each point temperature homogeneity around guaranteed product, meet the every technic index requirement of the board-like catalyst of SCR widely, improve catalyst activity, ensure product quality.
