Abstract
The utility model discloses a dust settling box of a coal handling system, which comprises a coal conveying channel, wherein the coal conveying channel is formed by a high-low blanking pipeline and a conveying belt which are butted with each other; a box body is arranged on the conveying belt, one end of the box body is butted with the blanking pipeline, and the other end of the box body is butted with a dust collection air pipe on the back surface of the box body; a plurality of dust boards are arranged in the box body, upper and lower air holes are respectively formed in adjacent dust boards, air holes are formed in the upper edges of inclined dust boards, and air holes are formed in the lower edges of vertical dust boards; and the lower parts of the dust boards are connected with soft plates. According to the utility model, through transformation of internal structure of the coal conveying channel, most of dust particles in dust airflow can be settled and fall off to the conveying belt to be sent away together with materials, so that the dust settling box of the coal handling system has the advantages of dust pollution reduction, energy saving and environmental protection.
Description
Technical field
The utility model relates to a kind of environmental protection equipment, more particularly, is a kind of coal handling system dust settling case that can stop in the Coal Transport process with the sedimentation dust.
Background technology
At present, the fortune coal mode that the coal handling system of coal-fired power plant generally adopts band conveyor that fuel is transmitted, height blanking place at each transfer point of coal handling system, coal-fired whereabouts impacts and produces a large amount of dust on the load-transfer device, and the defeated coal channel of present belt feeder is not provided with dust-arrest device especially; The existing dedusting fan that adopts carries out dedusting, but in actual moving process, Dust Capacity in the coal is too big, because existing structural limitations, be difficult to timely dedusting, the quick air-flow that forms the higher concentration dust is easily gushed from the dust-break curtain exit of deflector chute, and on-the-spot dust concentration seriously surpasses national environmental standard, cause environmental pollution, the harm health of human body.Also the someone adopts the method that increases air quantity to carry out dedusting, and coal dust is sucked out easily, causes the loss of coal.
The utility model content
The purpose of this utility model provide a kind of can eliminate effectively dust that drop brings to the influence of environment, reduce the coal handling system dust settling case that coal dust runs off.
The technical solution of the utility model is: a kind of coal handling system dust settling case, comprise defeated coal channel, defeated coal channel is made of height blanking pipeline and load-transfer device, both connect, wherein, be provided with casing at load-transfer device, one end and the blanking pipeline of described casing connect, the dust suction airduct of its other end and back connects, be provided with several dust boards in casing, be respectively equipped with upper and lower breather port on the two adjacent dust boards, preceding dust board is on top established breather port, then dust board is just established breather port in bottom, and the below of dust board is connected with the software plate.
Above-mentioned a kind of coal handling system dust settling case, described dust board is divided into vertical dust board and inclination dust board, and they are spaced successively and are arranged in the casing.Inclination dirt plate is on top established breather port, and vertical dirt plate is just established breather port in bottom, and the below of dust board is connected with the software plate.
Above-mentioned a kind of coal handling system dust settling case, the breather port that arranges on the dust board is two, is arranged side by side mutually.
Above-mentioned a kind of coal handling system dust settling case is provided with some observation doors at casing.
The utility model adopts above-mentioned structure, by being installed with some dust boards in casing, is respectively equipped with upper and lower breather port on the two adjacent dust boards, forms a curve gas channel of disturbance up and down in casing; When the dust air-flow of higher concentration pours in casing, the dust air-flow is subjected to the adhesion of dust board and stops, and the water conservancy diversion that is subjected to the curve gas channel slows down effect, and wind speed reduces, and the most of granule dust sedimentation in the dust air-flow is fallen on the load-transfer device, the dust of sedimentation is seen off with material, this structure can be slowed down the formation of dust to greatest extent, allows dust timely from exit output, has improved efficiency of dust collection, and can reduce dust pollution, energy-conserving and environment-protective; By be provided with some observation doors at casing, can observe the dust that the dust board in the casing adheres to, when dust is too much, can in time clear up; Because the coal of carrying height is different, by be provided with the software plate below dust board, can guarantee does not have the space between coal and the dust board.
Description of drawings
Fig. 1 is integral structure scheme drawing of the present utility model;
Fig. 2 is the structural representation of of the present utility model two adjacent front-and-back stop dirt plates.
Among the figure: 1 is casing, and 11 for observing door, and 2 are defeated coal channel, and 21 is load-transfer device, and 3 is the blanking pipeline, and 4 are the dust suction airduct, and 5 is dust board, and 51 is breather port, and 5a is vertical dust board, and 5b is the inclination dust board, and 6 is the software plate.
The specific embodiment
As depicted in figs. 1 and 2, a kind of coal handling system dust settling case, comprise defeated coal channel 2, defeated coal channel 2 is made of height blanking pipeline 3 and load-transfer device 21, both connect, be provided with casing 1 at load-transfer device 21, one end of casing 1 also connects with blanking pipeline 3, the dust suction airduct 4 of its other end and back connects, be provided with in casing 1 on the adjacent dust board 5 of several dust boards 5, two and be respectively equipped with upper and lower breather port, preceding dust board 5 is on top established breather port, then dust board 5 is just established breather port in bottom, and the below of dust board 5 is connected with software plate 6; Dust board 5 is divided into vertical dust board 5a and inclination dust board 5b, and they are spaced successively and are arranged in the casing 1; Breather port on dust board 5 is two, is arranged side by side mutually; Be provided with some observation doors 11 at casing 1.
The utility model in the specific implementation, the coal-fired a large amount of flour dust overflows of load-transfer device 21 generations that impact from blanking pipeline 3 whereabouts, dust enters into casing 1 under the effect of high velocity air, the dust air-flow is discharged from outlet through the breather port of some dust boards 5 by the effect of dust suction airduct 4.Most of dust is subjected to stopping of dust board 5 and adhesion and is settled down on the load-transfer device 21 and is seen off with material, the small part dust passes through stopping of some dust boards 5 and cushions, the wind speed reduction of dust air-flow and the concentration of dust air-flow are reduced, the dust of this small part is discharged from the outlet of dust suction airduct 4 at last, and the dusting equipment that is incorporated into the next stage setting carries out further dust removal process.
