Abstract
The utility model discloses an ultra -clean discharges wet -type and filters defogging dust collector, it includes a casing that is equipped with export and import down, is equipped with the filtration net system of the foldable imporosity that makes a round trip from top to bottom in the casing, filters the net system and is connected with housing seal, still being equipped with above the filter screen and supporting the steel pipe that filters the net system, the equipartition has the cold water nozzle on the steel pipe, requires the shower water of nozzle to cover whole filtration net system, being equipped with in the casing outside and possessing the circulation tank who deposits filtering capability, circulation tank establishes the circulating pump, and the circulating pump is connected with the steel pipe, and the wet return is established to the casing bottom, and wet return and circulation tank put through. Getting into the casing when dust -laden fog through lower import and when filtering the net system, filtering dirt particle and droplet on the wire side, absorb harmful substance through the shower water again, waste gas obtains purifying has realized the ultra -clean emission, filters the net system and washes away while filtering, guarantees the unblocked steady operation of filter screen, obtains precipitation and purification at circulation tank including the waste water of micronic dust, carries out cyclic utilization, the saving water source.
Description
Technical field
This utility model belongs to green technology, relates to the dust arrester of coal-burning boiler.
Background technology
At present, the environmental problem that commercial production causes is outstanding day by day, and such as haze weather happens occasionally.Cause mist
The reason of haze is also relevant with fire coal boiler fume discharge.Although coal-burning boiler all employ desulfation dust-extraction device, only
Change flue gas, but the waste gas discharged still has contained substantial amounts of fog and harmful gas.Therefore the row of pollutant is reduced
Put the key content becoming current research.China has put into effect a series of smog pollution thing discharge standard, and pollutant are arranged
Putting index even also strict than developed country, limit value as former in dust emission is less than 50mg/Nm3, specify mark afterwards
Standard is 20mg/Nm3, Thermal Power Generation Industry minimum discharge requires less than 5mg/Nm3。
In order to reach above-mentioned standard, the wet filter using electricity demister pattern having at present removes mist dust arrester, but
Power consumption water consumption is big, easily causes secondary pollution, does not reaches the minimum discharge requirement of regulation.
Utility model content
The purpose of this utility model is the deficiency overcoming electricity demister pattern, it is provided that a kind of ultra-clean discharge wet filter
Except mist dust arrester.
A kind of ultra-clean discharge wet filter is except mist dust arrester, it is characterised in that it includes that is provided with a upper outlet
With the housing of lower inlet, housing is provided with the drainage screen group of the most folding tight structure, drainage screen group
It is hermetically connected with the shell, divides housing 135 into admission space and air outlet space, particle dust can be made by drainage screen group
It is blocked on the wire side of admission space with droplet；It is also arranged above supporting the steel of drainage screen group at drainage screen
Pipe, steel pipe is evenly equipped with cold water nozzle, it is desirable to the shower water of nozzle covers whole drainage screen group, is sprayed by cold water
Drench and the particle dust being blocked in drainage screen group and droplet are rinsed in time, and reduce internal temperature elimination mist
Gas；Be provided with the cyclic water tank possessing precipitation filtering function in hull outside, cyclic water tank sets circulating pump, circulating pump
With fastener for connection, housing bottom sets return pipe, and return pipe is connected with cyclic water tank, made shower water recycle.
Operation principle below in conjunction with this utility model device illustrates its good effect.
When dust-laden fog is in lower inlet enters housing, through drainage screen group, dirt microgranule and droplet are filtered
On wire side, then absorbing harmful substance through shower water, waste gas is purified, and discharges from upper outlet, and final discharge is little
In 5mg/Nm3, it is achieved that ultra-clean discharge.Filtration limit, drainage screen group limit is washed away, it is ensured that the unimpeded stable operation of filter screen.
Waste water containing micronic dust is precipitated purification at cyclic water tank, is circulated utilization, saves water source.In cyclic water tank
Precipitate periodically processes, and forms solid, it is to avoid cause secondarily polluted water after filter pressing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model embodiment.
In figure: 1-housing, 2-upper outlet, 3-steel pipe, 4-cold water nozzle, 5-drainage screen group, 6-lower inlet,
7-return pipe, 8-cyclic water tank, 9-circulating pump.
Detailed description of the invention
As it is shown in figure 1, ultra-clean discharge wet filter of the present utility model is except mist dust arrester, it is provided with including one
The housing 1 of upper outlet 2 and lower inlet 6, is provided with the filtration of the most folding tight structure in housing 1
Net group 5, drainage screen group 5 is connected with housing 1, and housing 1 is divided into admission space and sky of giving vent to anger by drainage screen group 5
Between, particle dust and droplet can be made to be blocked on the wire side of admission space by drainage screen group 5；Filtering
Net group 5 is also arranged above supporting the steel pipe 3 of drainage screen group 5, and steel pipe 3 is evenly equipped with cold water nozzle 4, it is desirable to
The shower water of cold water nozzle 4 covers whole drainage screen group 5, will be blocked in drainage screen group 5 by cold water spray
Particle dust and droplet rinse in time, and reduce internal temperature eliminate fog；It is provided with tool outside housing 1
The cyclic water tank 8 of standby precipitation filtering function, cyclic water tank 8 sets circulating pump 9, and circulating pump 9 is connected with steel pipe 3,
Setting return pipe 7 bottom housing 1, return pipe 7 is connected with cyclic water tank 8, makes shower water recycle.
