The lower limb of described steelframe doorframe falls on described gutter channel central axis；
Described sparge pipe contacts with the top edge of described steelframe doorframe, offers a slit running through sparge pipe length direction head and the tail on the underface tube wall of described sparge pipe；
Described sparge pipe is connected with the reservoir outside return aircourse, stores dedusting liquid in described reservoir；
Described gutter channel one end is closed, and the other end is uncovered, and wherein, opening end is positioned at the top of the axis, gutter at the side of lane, return aircourse；
A number of hook it is evenly arranged with in the top outer rim of described steelframe doorframe, and on the steelframe canopy being suspended in return airway by described hook.
The technique effect that technique scheme is directly brought specifically includes that
1, form reliable and stable water curtain, ideal dedusting dust-laying effect can be reached；
2, simple in construction, the on-the-spot suitability are by force, install simple, cost and operating cost is cheap；
3, realistic problem/difficult problem of the installing space of special dedusting dust falling device and installation site in return airway is solved present in prior art, can be effectively by the wind Han dustiness produced by work surface, when entering return aircourse, preferably purified treatment, quality distinguished and admirable in improving underground coal mine return aircourse, it is ensured that underground operators healthy.
Being preferably, above-mentioned dedusting liquid is the middle water produced after sewage treatment plant's purified treatment in coal production process；Described middle water there was added surfactant-based foaming agent.
What this optimal technical scheme was directly brought has the technical effect that, use the middle water produced after sewage treatment plant's purified treatment in coal production process can reduce the operating cost of dust collector of water curtain, in middle water, there was added surfactant-based foaming agent, can preferably promote dedusting dust-laying effect.
Further preferably, above-mentioned gauze is two-layer, retains a determining deviation between layers.
What this optimal technical scheme was directly brought has the technical effect that, it is possible to achieve preferably dedusting dust-laying effect.
Further preferably, at the lower right position of above-mentioned screen window, it is additionally provided with one for the wicket installation doorframe of people's entry/exit；
The left frame of described wicket is rotatably connected by hinge formation with the left frame of described doorframe；
The version of described wicket is screen window.
What this optimal technical scheme was directly brought has the technical effect that, agrees with production reality, after dust arrester special in reducing return airway as far as possible is installed, and the negative effect brought accordingly.
Further preferably, the frame of above-mentioned screen window is made by aluminium alloy extrusions with the frame of described wicket.
What this optimal technical scheme was directly brought has the technical effect that, the frame of the frame of screen window and described wicket is made by aluminium alloy extrusions, and this is easy to standardization, large-scale production, manufacture；Two are, during assembling, (screw tightening operation simplicity, the attached auxiliary equipment of rubber press strip are easily obtained, and installation difficulty is low) is easy and simple to handle, production efficiency is high.
In sum, " owing to dedusting, depositing dust treatment technology, installing space (installation site) are limited; and the reason of the aspect such as Technical Economy; dusty gas dedusting, depositing dust process aspect (locally) in return aircourse is remained blank, does not does special gas purification or dust removal process " this technical problem/difficult problem that this utility model preferably solves that prior art exists；Can be effectively by the wind Han dustiness produced by work surface, when entering return aircourse, preferably purified treatment, quality distinguished and admirable in improving underground coal mine return aircourse, it is ensured that underground operators healthy.
This utility model, relative to prior art, has the beneficial effects such as simple in construction, manufacture and low, good, the stable and reliable operation of dedusting dust-laying effect of operating cost.
