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 formed
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 machineryization that benefit improves is horizontal so that the mining rate and production concentration degree of mine are significantly increased, and are the collection in colliery
Reduction operation and high-efficiency reform create 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 most important dust place of mine, the coal cutting of fully-mechanized mining working, coal breakage, move frame, reprinting,
Each links such as the cut of each links such as transport and fully mechanized workface, reprinting, transport produce a large amount of dust, seriously pollute periphery
Environment is simultaneously greatly threatened field personnel's health composition.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,
And one of maximally effective control dirt measure is exactly spray for dust suppression.Existing comprehensive mechanization getting working face 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 proves, uses at present
Spray for dust suppression measure can realize that the control to high concentrate dust removes 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 cause
Coal is increased by 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 dust-proof water consumption of colliery comprehensive mechanization getting working face, working face spraying is reduced to coal
The influence of matter, the synthesis dust prevention effect at coal-winning machine is improved, so as to farthest improve coal miner spray device dedusting
Effect, 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 is realized, 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
Can realize to provide one kind in flitting end face high-effective dust-removing, reduces the dedusting apparatus of water consumption,
High concentrate dust caused by closing coal cutting while spray for dust suppression, it is prevented to expansion at coal-winning machine driver and lower air port timberer
Dissipate, the present invention adopts the following technical scheme that.
A kind of new and effective coal-winning machine wet scrubber, deduster are arranged on rocker arm of coal mining machine, including be sequentially connected
