The problems such as coal losses, high coal-fired moisture.As atmosphere polluting problem is increasingly severe, country and local government put into effect policy in succession,
It is required that being closed to coal-burning power plant's coal yard.
Currently, part power plant coal yard has been carried out totally-enclosed transformation, but a series of problems is exposed during operation.For reality
Existing coal yard ventilation, closing coal yard bottom is surrounded by row's ventilation hole, top is equipped with dormer, realization lower part gravity-flow ventilation,
Top natural exhaust, when strong wind weather, air is blown into closing coal yard by hole, and coal yard is caused largely to play dirt.It is suspended in closing
Dust in coal yard causes to seriously endanger to coal yard staff's occupational health；Part dust is conveyed into air by hole, right
Local environment adversely affects.
Invention content
It is an object of the invention to overcome the above-mentioned prior art, a kind of closing coal yard and its work side are provided
Method, the coal yard and its working method can improve flow field and ventilation effect in coal yard, and cost of investment is low, prevents coal
Dirt is played in field, limits dust recycling.
In order to achieve the above objectives, closing coal yard of the present invention includes solid wall, wall interior panel and ventilation clerestory, wherein
Solid wall and wall interior panel are loop configuration, and wall interior panel is located on solid wall, and ventilation clerestory is set at the top of wall interior panel and opens
At mouthful, the side of wall interior panel offers ventilation hole, and filter drift net is both provided in the side of ventilation clerestory and ventilation hole, filters on drift net
It is provided with several holes.
Ventilation hole is distributed in a ring.
The number of ventilation hole is 1.
The number of ventilation hole is more than or equal to 2, and each ventilation hole is sequentially distributed from top to bottom.
It further include the rigid strutting piece for being used to support wall interior panel.
The cross section of structure that solid wall, wall interior panel and filter drift net surround be semicircular structure, three-core circular configuration or
Rectangular configuration.
It is flat structure or butterfly architecture to filter drift net.
It is provided with deflector on filter drift net and wall interior panel.
Deflector is that either the shape of perforated panel and deflector is plate or butterfly-type to solid slab.
The working method of closing coal yard of the present invention includes the following steps：Air-flow is after filter drift net weakens stream monsoon intensity
It enters in the structure that solid wall, wall interior panel and filter drift net surround, with the flow field in optimization closing coal yard, then again through gas of divulging information
It flows out in building.
The invention has the advantages that：
Closing coal yard of the present invention and its working method realize that coal yard ventilation is changed when specific operation by filtering drift net
Gas weakens incoming monsoon intensity by filtering drift net, reduces wind load, improve incoming wind turbulence structure, optimizes closing coal yard flow field,
Improve the working environment of coal yard, improve employee's labour occupational health level, the wind speed in coal yard is down to drift speed hereinafter, Du
Exhausted coal yard plays dirt, limits dust recycling, since the wind load of coal yard is relatively low, to save the steel using amount of closing coal yard, investment at
This is relatively low, is computed, by taking 50,000 tons of coal yards as an example, using the present invention can 4,000,000 yuan of investment reduction, while anti-dust effect is reachable
To 100%, can be widely applied to coal-burning power plant's coal yard and its in industrial stock ground.
