Abstract
The utility model relates to industrial furnace denitrating flue gas urea and carries material equipment, a kind of denitrating flue gas urea of concrete proposition strength feeding device, main feature adopts by conveying pipeline, separator, blower fan, backwind tube be connected successively build enclosed wind circulating line, by ground urea through hopper, after batcher enters liter material conveying pipeline, fluent strength enters separator with the wind, from conveying wind, isolated urea adds in the urea dissolving tank of below, distinguished and admirable returning through blower fan is circulated into backwind tube, compared with existing bucket elevator material-uploading style, there is structure simple, reliable, manipulation is convenient, the advantages such as the problem of urea bonding and ammonia environmental pollution and rotten damage equipment can be solved.
Description
Technical field
The utility model belongs to industrial furnace denitrating flue gas field, relates to denitrating flue gas urea and carries material equipment, specifically a kind of denitrating flue gas urea strength feeding device.
Background technology
Existing Industrial Boiler, kiln gas denitration, adopt urea denitration, utilizes bucket elevator promoted from ground by urea granules and be transported in urea dissolving tank.But, in the bucket elevator conveying process used at present, there is following technical problem urgently to be resolved hurrily:
1, bucket elevator complicated structure, in operation, easily there was a mechanical failure, and maintenance capacity is larger;
2, lift bucket inwall is easily bondd by urea, constantly bonds, and not only can affect and put forward doses, but also need shut down removing bonding, and impact is produced;
3, promote conveying system bad sealing, the ammonia that urea produces can pollute to equipment corrosion and to operating environment.
Summary of the invention
Promote to solve current industrial furnace denitrating flue gas urea the technical problem existed in conveying, the purpose of this utility model is to provide a kind of novel denitrating flue gas urea strength feeding device, can overcome preferably and solve the problems of the technologies described above.
Technical solution adopted in the utility model is a kind of denitrating flue gas urea strength feeding device of design, its structure comprises: frame, hopper, batcher, is communicated with a liter material conveying pipeline at the material inlet of batcher, is communicated with separator in a liter upper part discharge port for material conveying pipeline, the lower nozzle of conveying pipeline is communicated with backwind tube by volume damper, backwind tube is communicated with blower fan, and the air inlet of blower fan is connected with the gas outlet of separator, and the feed opening of separator is connected with urea dissolving tank.
The utility model adopts the measure of technique scheme, existing denitrating flue gas urea bucket elevator charging equipment is improved, designed this denitrating flue gas urea strength feeding device, wherein being connected successively by conveying pipeline, separator, blower fan, backwind tube, to construct enclosed wind circulating line distinguished and admirable, during the work of this device, first start blower fan, by adjustment volume damper, make enclosed wind circulating line wind speed be stabilized in certain wind speed; Open hopper bottom batcher, work well, control feeding coal according to upper doses adjustment; Urea is added material bin, urea evenly enters conveying pipeline through batcher, and it is distinguished and admirable with conveying, utilize strength to enter separator through conveying pipeline, in separator, urea granules is separated from conveying wind, enter in urea dissolving tank, conveying wind enters backwind tube by blower fan foldback, includes enclosed wind circulating line in, again completes the closed loop operation of urea strength material loading.
Compared with prior art, denitrating flue gas urea strength feeding device of the present utility model has the following advantages:
1, this apparatus structure is fairly simple, reliable, and manipulation is convenient, and maintenance and repair amount reduces;
2, this apparatus system closed operation, effectively prevent the ammonia of urea generation to the pollution of environment and rotten damage equipment;
3, eliminate lift bucket, overcome urea adhesion problem, drastically increase and carry doses and operating efficiency.
Accompanying drawing explanation
Fig. 1 represents the general structure schematic diagram of the utility model denitrating flue gas urea strength feeding device.
Detailed description of the invention
In conjunction with the accompanying drawings and embodiments, concrete structure of the present utility model is further illustrated.
The embodiment of the utility model denitrating flue gas urea strength feeding device, see Fig. 1, its structure comprises: frame 1, hopper 3, batcher 4, a liter material conveying pipeline 6 is communicated with below the material inlet of batcher, whizzer 8 is communicated with in a liter upper part discharge port for material conveying pipeline, backwind tube 5 is connected with by volume damper 2 in a liter lower nozzle for material conveying pipeline, backwind tube is communicated with blower fan 7, the air inlet of blower fan 7 is connected with the gas outlet of whizzer 8, the feed opening of whizzer 8 is connected with the urea dissolving tank 9 of below by tube connector, utilize closed wind to circulate to realize the closed loop operation of ground urea strength material loading.
Model machine is through trying out in Zhong electricity Tou Nanyang Thermal Power Co., Ltd (2 × 200MW) and Nanyang Yahekou (sky benefit) Power Generation Corporation Ltd. (2 × 350MW+2 × 600MW) workshop section installation, respond well, solves the technical problem that prior art exists ideally.
