Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust treatment, in particular to a bag dust removal and spray collaborative dust reduction device. Background Technique
[0002] Coal is one of the main energy sources. The storage method of coal has gradually developed from an open coal yard to a semi-closed and closed coal yard (i.e., a coal storage shed). During the coal loading process in the coal storage shed, dust is easily generated, which not only easily causes serious environmental pollution, but also may cause fires or even explosions when the concentration of dust and flammable gases volatilized from coal reaches a certain level, thus affecting safe production and even causing casualties. The existing common dust reduction methods mainly suppress dust on-site through steam and water, and there are also those that use spray dust reduction, but the dust reduction effects are not ideal. Summary of the Invention
[0003] In order to solve the problem that the dust reduction effect of the existing common dust reduction methods is not ideal, the utility model provides a new bag dust removal and spray collaborative dust reduction device.
[0004] The utility model is realized by adopting the following technical scheme:
[0005] A bag dust removal and spray collaborative dust reduction device includes a spray mechanism and a dust removal mechanism;
[0006] The spray mechanism includes a water storage tank and a plurality of high-pressure branch pipes arranged on the inner top and around of the coal storage shed. After the plurality of high-pressure branch pipes are combined into a high-pressure main pipe, they are all connected to the water storage tank through a high-pressure pump (which is well known to those skilled in the art and consists of an air compressor and a water pump), and a plurality of high-pressure nozzles are evenly arranged on each high-pressure branch pipe;
[0007] The dust removal mechanism includes a plurality of dust suction hoods respectively arranged at a plurality of dust generation points in the coal storage shed and a plurality of dust suction branch pipes. One ends of the plurality of dust suction branch pipes are respectively fixedly connected to the plurality of dust suction hoods, the other ends of the plurality of dust suction branch pipes are all connected to one end of a dust suction main pipe, the other end of the dust suction main pipe is connected to a bag dust collector, and the bag dust collector is also equipped with an induced draft fan.
[0008] Principle description: By periodically spraying the coal storage shed through the spray mechanism, on the one hand, the humidity of the raw coal can be increased, effectively reducing the dust generated during the coal loading process of the raw coal, playing a role in advance dust suppression. On the other hand, the coal dust in the air in the coal storage shed can also be fogged down, realizing large-area dust control and suppression. At the same time, the dust at the dust generation points in the coal storage shed is sequentially removed by the dust suction hood, dust suction branch pipe, dust suction main pipe, and bag dust collector, and then led out to the discharge cylinder through the induced draft fan. After detection, the average emission concentration is 6.1 mg / m 3 , reaching 10 mg / m which meets the environmental protection requirements 3The following emissions, and the dust collected after being treated by the bag filter can be recycled and transported to the dry coal shed for co-firing in the power boiler to reduce the consumption of fuel coal.
[0009] Furthermore, there are four dust suction hoods arranged at the belt conveyor in the coal storage shed, which are respectively arranged at the head, tail and two intermediate positions of the belt conveyor, further ensuring the dust removal effect.
[0010] Furthermore, four dust suction hoods are evenly arranged at the two dust generating points at the storage hopper in the coal storage shed, further ensuring the dust removal effect.
[0011] Furthermore, the length of each high-pressure branch pipe is 24 meters.
[0012] Furthermore, 13 high-pressure nozzles are evenly arranged on each high-pressure branch pipe.
[0013] The beneficial effects produced by the present utility model are as follows: The dust reduction device described in the present utility model plays a role in synergistic dust reduction of bag dust removal and spraying, with obvious dust reduction effect, realizing a safe and clean on-site environment, effectively reducing the dust during the transfer process of raw coal, and at the same time, by using the bag filter, not only the discharged gas meets the emission standards, but also the treated dust can be recycled to achieve the effect of cost reduction and efficiency increase.
