Description
Technical field
The present invention relates to a kind of mining synthesis dust prevention equipment, more particularly to a kind of flitting dedusting equipment.
Background technology
China is coal production state and country of consumption maximum in the world, and consumption of coal accounts for what China's energy overall consumption was constituted
More than 70%, it is predicted that the year two thousand fifty can still account for 60%, therefore coal mining plays vital effect in national economy.Day
The coal mining machinery level that benefit is improved so that the mining rate and production concentration degree of mine are significantly increased, and are the collection in colliery
Reduction is managed and high-efficiency reform creates good condition, but mine dust yield is more and more more, and dust problem becomes day
It is beneficial serious.
Getting working face is one of topmost dust place of mine, the coal cutting of fully-mechanized mining working, coal breakage, move frame, reprinting,
Each links such as cut, reprinting, the transport of each links such as transport and fully mechanized workface produce a large amount of dust, severe contamination periphery
Environment is simultaneously greatly threatened the healthy composition of field personnel.Factually survey, do not using the situation of any dust prevention
Under, moment dust concentration during fully-mechanized mining working production operation may be up to 6000 mg/m3.At present, underground coal mine it is the most frequently used,
It is also that one of maximally effective control dirt measure is exactly spray for dust suppression.Existing comprehensive mechanization getting working face, which is mainly, relies on coal-winning machine
The atomizing dust-removing system carried is controlled to the high concentrate dust during coal petrography cutting.Field measurement is proved, is used at present
Spray for dust suppression measure can realize that the control to high concentrate dust is removed to a certain extent, but at this stage used in digging operation
Spray dust remover form is single, and the selection of atomizer only relies on subjective experience, does not have scientific basis, which results in digging
The nozzle atomization ability of operation field is poor, and spray for dust suppression is less efficient, and nozzle water consumption is big so that underground coal mine water consumption increases
Greatly, and a large amount of ponding in getting working face scene, the operating environment of getting working face is not only degrading, what is more important will be caused
Increase coal water content in working face output procedure, so that heating value of coal changes, cause quality inspection, the meter of coal
Amount, examination, management and the economic benefit of enterprise are by a certain degree of influence.
Therefore, in order to reduce the water consumption that colliery comprehensive mechanization getting working face is dust-proof, working face spraying is reduced to coal
The influence of matter, improves the synthesis dust prevention effect at coal-winning machine, so as to farthest improve coal miner spray device dedusting
Effect, realizes the present situation for improving that spray for dust suppression water consumption is more, spraying is big to heating value of coal and effect on coal quality, improves mine economy
Benefit has extremely important effect, for instructing the safety in production of industrial and mining enterprises also to have important theory significance and practical valency
Value.
The content of the invention
It can be realized in flitting end face high-effective dust-removing to provide one kind, reduce the dedusting apparatus of water consumption,
The high concentrate dust that coal cutting is produced is closed while spray for dust suppression, it is prevented to expansion at coal-winning machine driver and lower air port timberer
Dissipate, the present invention is adopted the following technical scheme that.
A kind of new and effective coal-winning machine wet scrubber, deduster is arranged on rocker arm of coal mining machine, including be sequentially connected
