Description
Technical field
The utility model belongs to coal-burning power plant's closing coal yard technical field, is related to a kind of closing coal yard.
Background technique
Coal-burning power plant's coal yard is mostly outdoor arrangement, is only surrounded by wind-proof dust-suppression net in coal yard, and there are dust pollutions, combustion
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 atmosphere by hole, right
Local environment adversely affects.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of closing coal yard, the coal yard
The flow field in coal yard and ventilation effect can be improved, and cost of investment is low, prevent coal yard and play dirt, limit dust recycling.
In order to achieve the above objectives, closing coal yard described in the utility model includes solid wall, wall interior panel and ventilation clerestory,
In, solid wall and wall interior panel are ring structure, and wall interior panel is located on solid wall, and ventilation clerestory is set to the top of wall interior panel
Opening, the side of wall interior panel offer ventilation hole, and filter drift net is provided in the side of ventilation clerestory and ventilation hole, filter drift net
On be 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.
Filtering drift net is flat structure or butterfly architecture.
Deflector is provided on filter drift net and wall interior panel.
Deflector is that perhaps the shape of perforated panel and deflector is plate or butterfly-type to solid slab.
The utility model has the advantages that：
Closing coal yard described in the utility model is realized coal yard ventilation by filter drift net, is passed through when specific operation
It filters drift net and weakens incoming flow monsoon intensity, reduce wind load, improve incoming flow wind turbulence structure, optimization closing coal yard flow field improves coal
The working environment of field improves employee's labour occupational health level, the wind speed in coal yard is down to drift speed hereinafter, preventing coal yard
Dirt is played, dust recycling is limited, since the wind load of coal yard is lower, to save the steel using amount of closing coal yard, cost of investment is lower,
It is computed, can be 4,000,000 yuan of investment reduction using the utility model by taking 50,000 tons of coal yards as an example, while anti-dust effect can reach
100%, can be widely applied to coal-burning power plant's coal yard and its in industrial stock ground.
