Description
One, technical field
The utility model belongs to kiln auxiliary equipment, relates in particular to one and divides wind apparatus for the board-like catalyst calcination stove of SCR.
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.
Because this SCR plate-type denitration catalyst is vertical calcining, air stratification can be avoided like this, but the hot air circulation of whole torus has 180o to turn in whole flow field, it is uneven that hot blast after turning enters catalyst prod, some positions hot blast rate is large, and some places hot blast rate is little, often easily makes catalyst plates decorated fire, not only greatly affect product quality, even also there will be many waste products.
Three, summary of the invention
The purpose of this utility model is for prior art Problems existing, design a kind of rational in infrastructure, make simple, easy for installation, dividing equally property good divide wind apparatus for the board-like catalyst calcination stove of SCR.
The technical solution of the utility model is: it arranges and to form circulating air chamber by being arranged on calcining furnace burner hearth both sides and top between dividing plate and inwall and be arranged on the airtight hot air circulation duct that the product carrying case inner catalyst product etc. on chassis forms, bottom product carrying case, be provided with the sieve plate putting catalyst prod, and be provided with air inlet duct between sieve plate and chassis.These air inlet duct both sides are all provided with two pieces of split-wind plates and are divided into three layers of branch air duct, and make circulating air evenly enter each interval gap of catalyst prod, the air outlet that air inlet duct both sides air inlet is arranged with bottom, calcining furnace Inner eycle air channel communicates.
The beneficial effects of the utility model are: owing to being provided with sieve plate bottom the product carrying case on chassis, and split-wind plate is provided with in air inlet duct, thus make from the chassis that circulation air path air outlet docks is separated after three layers of air intake evenly send into different intervals, the air intake in each interval is again through sieve plate equal wind again, most relief hot blast enters product from bottom to top equably, thus it is consistent to ensure that product often puts heat, only need control EAT and intake well, just fully can ensure that the burning quality of product, improve board-like catalyst activity.
Below in conjunction with accompanying drawing, the utility model is further described.
Four, accompanying drawing explanation
Fig. 1 is the utility model cross section structure schematic diagram.
In figure: 1 is air outlet, 2 is air inlet, and 3 is split-wind plate, and 4 is sieve plate, and 5 is chassis, and 6 is catalyst prod, and 7 is product carrying case, and 8 is circulating air chamber, and 9 is calcining furnace, and 10 is dividing plate, and 11 is air inlet duct.
Five, detailed description of the invention
As shown in Figure 1, wind apparatus is divided to be to form circulating air chamber 8 between dividing plate 10 and inwall by arranging in calcining furnace 9 burner hearth both sides and top and be arranged on the airtight hot air circulation duct that the product carrying case 7 inner catalyst product 6 etc. on chassis 5 forms for SCR board-like catalyst vertical continuous calcining furnace chassis, the sieve plate 4 putting catalyst prod 6 is provided with bottom product carrying case 7, and air inlet duct 11 is provided with between sieve plate 4 and chassis 5, these air inlet duct 11 both sides are all provided with upper and lower two pieces of split-wind plates 3 and are divided into three layers of branch air duct, circulating air is made evenly to enter each interval gap of catalyst prod 6, the air outlet 1 that air inlet duct 11 both sides air inlet 2 is arranged with bottom, calcining furnace 9 Inner eycle air channel 8 communicates.When implementing the utility model, calcining furnace 9 is provided with circulating air chamber 8, exported 1 by the hot-air after heating by the wind of hot bottom, circulating air chamber in circulating air chamber and enter air inlet duct 11 above chassis 5, bottom air inlet 2 place to be divided into product carrying case 7 that multiply hot blast enters on chassis 5 by split-wind plate 3, each is interval, then by just entering each the interval gap being placed in product carrying case 7 inner catalyst product 6 after sieve plate 4 again equal wind, uniform calcination is carried out to product.Due to sieve plate 4 having a lot of sieve aperture, product every nook and cranny can be flowed to equably by the hot blast behind sieve plate hole, not have dead angle and occur.SCR plate-type denitration catalyst is it is crucial that its activity, uniform temperature field is very important to the calcining of catalyst, the utility model have rational in infrastructure, make the advantages such as simple, easy for installation, dividing equally property is good, fully can meet the technological requirement of product calcining, ensure the quality of catalyst prod, stop to occur waste product.
