Technical field
The utility model relates to a kind of aeration and biological filter tank, the particularly auxiliary gas feeder in a kind of aeration and biological filter tank.
Background technology
Thermal power plant boiler becomes water into high pressure steam, then generates electricity with high pressure steam pushing turbine. Needing constantly to boiler replenishing water when heat power plant boiler runs, water consumption is very big, and the water quality requirement of boiler make-up water is also very high.
Usual thermal power plant is with the natural water of earth's surface or underground as water source, day by day in short supply along with natural water resource, and more and more thermal power plants brings into use city recycled water as water source. Containing having certain suspension and chemical substance in the water at above-mentioned water source, supply heat power plant boiler is as before make-up water, it is necessary to processed by the water at above-mentioned water source with water treatment facilities. A kind of typical heat power plant boiler make up water treatment device by water source of city recycled water has preceding aeration and biological filter tank and posterior filtration device and desalting water treatment device.
There is connected filter tank in aeration and biological filter tank and supplies device of air, there are water inlet and delivery port in filter tank, filtrate it is filled with in filter tank, it is evenly equipped with aeration head at the bottom of the pond in filter tank, aeration head is connected with the air intake pipe stretching out outside filter tank, air intake pipe is connected with Manual air inlet valve and Pressure gauge, has air blast for device of air, air blast has airduct, goes out and is connected with manual outlet valve and check valve on airduct. During use, allowing water enter filter tank through water inlet, blast air by aeration head with air blast in the water in filter tank, the water in filter tank, after aeration biochemical thing processes, flows out to from delivery port and filters device and desalting water treatment device and process further.
In prior art, aeration and biological filter tank only has the confession device of air of air blast in a road, when air blast generation fault needs maintenance down, cannot blast air to filter tank, cause filter tank out of service, affect thermal power plant normal power generation.
In addition, containing suspension, number of chemical material etc. in the water at above-mentioned water source used, thermal power plant, after one period is run in aeration and biological filter tank, aeration head uniform at the bottom of filter tank can block, aeration head blocking will cause the water treatment efficiency affecting filter tank because filter tank cloth gas is uneven, aeration head blocking also cause blower export smooth so that cause air blast overheated, go out abnormal phenomenons such as mouth pressure height, filter tank gas distribution system explosion can be caused during Severe blockage.
For solving the problem of aeration head blocking, in prior art, it is take the mode changing aeration head to overhaul, because aeration head is arranged in bottom filter tank, filtrate it is filled with in filter tank, change aeration head time must first the filtrate in filter tank be drawn out, more block change aeration head after backfill filtrate again, again cultivate microorganism film. The problem solving aeration head blocking in this way is taken a lot of work, time-consuming, expense big, causes the problem solving aeration head blocking pretty troublesome.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is proposed to a kind of problem solving aeration head blocking is simple, need the aeration and biological filter tank with auxiliary gas feeder that still can normally run during maintenance down when air blast generation fault.
The utility model realizes with the following method.
There is connected filter tank in the aeration and biological filter tank with auxiliary gas feeder and supplies device of air, there are water inlet and delivery port in filter tank, filtrate it is filled with in filter tank, it is evenly equipped with aeration head at the bottom of the pond in filter tank, aeration head is connected with the air intake pipe stretching out outside filter tank, air intake pipe is connected with Manual air inlet valve and Pressure gauge, air blast is had for device of air, air blast has airduct, go out and airduct is connected with manual outlet valve and check valve, go out airduct to be connected with air intake pipe, auxiliary gas feeder also it is connected with at air intake pipe, auxiliary gas feeder has compressed air storage tank, compressed air storage tank has compressed air inlet and compressed air outlet, compressed air outlet is connected with compressed air pipe, compressed air pipe has check valve and manual valve, compressed air pipe is connected with air intake pipe.
During use, the compressed air inlet of above-mentioned compressed air storage tank should be connected with for device of air, and the pressure of compressed air storage tank compressed air should be greater than the pressure of needs when aeration and biological filter tank is run.
Above-mentioned compressed air storage tank can utilize the compressed air for instrument storage tank in boiler of power plant make up water treatment system, the pneumatic element movement that the compressed air in compressed air for instrument storage tank is used in driving control system.
The entrance of above-mentioned compressed air for instrument storage tank is connected with power plant main power house compressed air system, ensure that the gas pressure in compressed air for instrument storage tank is between 0.5MPa ~ 0.7MPa, what the pressure of tank compressed air was greater than above-mentioned air blast goes out mouth pressure, and namely the gas pressure in compressed air storage tank is greater than the pressure of needs when aeration and biological filter tank is run.
Above-mentioned compressed air for instrument storage tank has and the gas outlet that compressed air for instrument user is connected, and in order to not affect compressed air for instrument user, compressed air outlet can be connected in blowdown pipe, and described blowdown pipe is connected with sewage door.
When the utility model normally runs, close the manual valve on compressed air for instrument storage tank compressed air pipe, only in the water in filter tank, blast air by aeration head with air blast. When aeration head blocking affects the water treatment efficiency in filter tank, temporarily close air blast, close air blast and go out the manual outlet valve on airduct, open manual valve on the compressed air pipe of compressed air tank, the compressed air higher with the pressure in compressed air storage tank impacts aeration head, solving the problem of aeration head blocking, the problem that solution aeration head is blocked is very simple. After solving the problem of aeration head blocking, more manual valve on the compressed air pipe of closes compression air tank, open air blast, open air blast and go out the manual outlet valve on airduct, recover the utility model normal operating condition.
The utility model has and has the main for device of air of air blast, has the auxiliary gas feeder of compressed air storage tank in addition. When air blast function is normally run, blast air for device of air to filter tank with having the main of air blast; When air blast generation fault needs maintenance down cannot blast air to filter tank; close air blast; closing air blast and go out the manual outlet valve on airduct, open manual valve on the compressed air pipe of compressed air tank, the compressed air higher with the pressure in compressed air storage tank blasts air to filter tank. Owing to the gas pressure in compressed air storage tank is greater than the pressure of needs when aeration and biological filter tank is run, when blasting air with auxiliary gas feeder to filter tank, need the aperture regulating manual valve on the compressed air pipe of compressed air storage tank, use the pressure that air pressure power is applicable to needs when aeration and biological filter tank is run.
Below in conjunction with accompanying drawing, the utility model is further described.
