Abstract
The invention relates to a water-curtain dust fall system of a storage bunker, which is characterized in that a fixed frame is hanged in the air of the storage bunker by a steel wire rope, and a lifting system is arranged below the fixed frame; the lifting system comprises an electric hoist and a U-shaped frame, the electric hoist is fixed below the fixed frame and connected with the U-shaped frame by an electric-hoist steel wire rope, the inside of the U-shaped frame is provided with a spray pipe, and the spray pipe is provided with a plurality of spray nozzles; a pump room is arranged in the storage bunker, a water tank is arranged in the pump room, the water outlet of the water tank is connected with a water supply pipe, and the water inlet of the water tank is connected with a return water pipe; the water supply pipe and the return water pipe are both communicated with the spray pipe; and the water supply pipe and the return water pipe are respectively provided with a plurality of butterfly valves. The water-curtain dust fall system provided by the invention has the advantages of improving the working environment, achieving the effects that no dust flies in the coal bunker and the dust-fall rate is 100 percent, realizing the water-curtain dust fall, having a good atomization effect, and not affecting the effect of water-curtain dust fall, and achieving the effect that no dust is generated within hours after a coal pile is covered with water mist.
Description
Technical field
The present invention relates to a kind of dust falling device, especially a kind of to coal store water curtain dust falling system, belong to the environmental protection equipment field.
Background technology
Coal yard is the important step of coal transhipment, and its scale is determined by turn-over capacity.In China, coal yard is open work mostly, and in the transhipment operation process, the dust that is produced fills the air whole coal yard, and dust waves with the wind, the severe contamination surrounding enviroment.
In order to solve the pollution problem to external environment condition, some enterprises with the consciousness of far looking forward or upwards and environmental protection idea begin to design the coal yard of closed operation.This method will inevitably become one of direction of following coal yard design.Coal yard is the complete closed operation.But though closed coal yard has solved the pollution problem of coal yard to external environment condition, its enclosure space is inner because finite volume; Operation is frequent, causes dust pollution serious, and concentration increases; Not only endanger the healthy of field operation workman, and bring potential safety hazard.The reason of analyzing its dust generation mainly contains two types:
(1), Transport Machinery and vehicle frequently come in and go out and drive coal yard surface granule coal dust, causes airborne dust;
(2), the drop transporting and produce when unloading makes material push mutually, collision, and air-flow makes coal crusher and along with ascending air is floating in coal store;
(3), confined space dome, wall and other building structure and equipment absorption fine particle dust, after receiving external disturbance, activate again, cause airborne dust.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of coal store water curtain dust falling system that improves working environment is provided, reaching coal store does not have that dust waves, dust reduction rate 100%.
According to technical scheme provided by the invention, a kind of coal store water curtain dust falling system, characteristic is: it is aerial to adopt steel wire rope that fixed mount is hung at coal store, and jacking system is installed below fixed mount; Said jacking system comprises electric block and U type frame, and said electric block is fixed on the below of fixed mount, and electric block is connected with U type frame through the electric block steel wire rope, in U type frame, spray piping is installed, and several shower nozzles distribute on spray piping.
In said coal store, pump house is set, in pump house, disposes water tank, the delivery port of water tank is connected with water supply line, and the water inlet of water tank is connected with water return pipeline.Said water supply line and water return pipeline all are communicated with spray piping.
A plurality of butterfly valves are set on said water supply line and water return pipeline.
Advantage of the present invention:
1, the present invention can improve working environment, and reaching coal store does not have that dust waves, dust reduction rate 100%;
2, can realize the water curtain depositing dust, atomizing effect is good, does not influence the water curtain dust-laying effect;
3, after covering water smoke on the dump, can reach several hours and not play dirt.

The specific embodiment
Below in conjunction with specific embodiment the present invention is described further.
Like Fig. 1～shown in Figure 5: coal store water curtain dust falling system comprises jacking system 1, shower nozzle 2, butterfly valve 3, water supply line 4, pump house 5, water return pipeline 6, steel wire rope 7, fixed mount 8, electric block 9, electric block steel wire rope 10, U type frame 11, spray piping 12 etc.
The present invention adopts steel wire rope 7 to hang at coal store fixed mount 8 aerial; Jacking system 1 is installed below fixed mount 8; Said jacking system 1 comprises electric block 9 and U type frame 11, and said electric block 9 is fixed on the below of fixed mount 8, and electric block 9 is connected with U type frame 11 through electric block steel wire rope 10; Spray piping 12 is installed in U type frame 11, and several shower nozzles 2 distribute on spray piping 12.
Said electric block is a kind of small-sized hoist engine, can buy on the market.
On said water supply line 4 and water return pipeline 6, a plurality of butterfly valves 3 are set.
The course of work of the present invention: when in the coal store dust being arranged, pump house 5 is started working, and through water supply line 4 water is fed in the spray piping 12; Spray through shower nozzle 2; When needs reduce the height of spraying, start electric block 9, reduce the height of U type frame 11 through electric block steel wire rope 1; After the spraying end of job, the water in the spray piping 12 is flow back to the water tank 13 in the pump house 6 through water return pipeline 6.
