To pass through the chimney combustion gas during boiler work; wherein contain various as pernicious gases such as dust, sulfur dioxide, nitric oxides; especially when fuel combustion is insufficient; regular meeting discharges billowing black smoke; it is the coke solids particle of incomplete combustion, and waste gas then is the arch-criminal of contaminated environment.For this reason, people have taked multiple way to go to purify harmful substance in the boiler institute waste discharge gas, as various wet type flue gas cleaners etc., its cardinal principle is exactly directly by pipeline waste gas to be introduced one to have in water receptacle or the pond, waste gas is carried out multiple udst separation operation such as water spray, self-excitation and water film filtering purify flue gas, its desulfurization removing nitric is eliminated smoke, remove pernicious gases such as dust and sulfur dioxide, nitric oxide, the dirt ash in container or the water pool inner water then adopts technology such as precipitation to prevent the sewage secondary pollution.As Chinese patent communique invention disclosed patent " purifying method for boiler fume and equipment thereof ", (92103594.2), it is once finished by flue gas shunting, dust removal by filtration, the desulfurization of spray mixed flow, dust discharging, and it is characterized in that carrying out spraying cooling after flue gas enters cleaning equipment: flue gas enters and passes through spraying cooling; The shunting depositing dust; Flue gas makes the multidirectional shunting diffusion of flue gas, slows down flow velocity and pressure through slow resistance shunting; The desulfurization of spray mixed flow: flue gas is provided with 1.5～2Kg/cm ↑ [2] through the spray flow mixing device and sprays in the water resistance and harmful gas, and it is poor to change the exchange interaction district, and water, gas, dirt mix and touches aggegation; Dust removal by filtration: flue gas is W shape or V-arrangement filter disc group obstruction and sealing water curtain for dust-collecting through curved surface.The desulfurization of secondary spraying mixed flow, dust removal by filtration can repeat 2～5 times; Gas-water separation: the plate that sets obstacles divides dried up, gas, is cleaned flue gas and discharges from the gas outlet.Automatically unload dirt: the dust moisture aggregation that will hinder filter is discharged automatically to dust unloading wheel.Also has utility model patent " high-efficiency wet-type dust collector " (90213023.4); comprise tower body, exhaust gas inlet, water inlet pipe, the smart clean room of S shape, dirt pocket, overflow mechanism (comprising downflow weir, overflow pipe and spout hole), scarfing cinder pond, sedimentation basin, branch fog chamber, baffle device for water and purifying exhaust air outlet, also have the shutdown water level governor motion that combines with the overflow mechanism structure.The structure of these schemes is all complicated, all be primarily focused in addition and how waste gas handled, some characteristics of discharging waste gas did not then add attention when boiler was worked, as the stress problems that scavenges, owing to waste gas will be discharged from the wet type flue gas cleaner is to need certain pressure, in addition, when boiler is flame-out, can produce negative pressure in the pipeline, produce problems such as water in the wet type flue gas cleaner recharges sometimes.
Summary of the invention
Purpose of the present invention, just provide a kind of simple in structure, and regardless of boiler emission exhaust gas discharging pressure condition, also normal discharging waste gas under the situation of boiler work itself can not influenced, and when boiler is flame-out, effectively prevent the boiler waste gas purification device that waste water recharges.
For achieving the above object, boiler waste gas purification device of the present invention, it is characterized in that: form: described pipeline one termination boiler waste gas floss hole by wet scrubber, pipeline, pressue device, air door and controller, through but pressue device being housed behind the damper, behind a unidirectional air door, arranging in the water of wet scrubber again, but but damper pre-installed have baroceptor and one with the extraneous damper that communicates, but each damper and sensor have control line to link to each other with controller.
Described pressue device is blower fan or air compressor.
Described pipeline is horizontal behind unidirectional air door, have a plurality of export places to arrange in the wet scrubber water.
Described wet scrubber has agitating device in the pond; At least one spray equipment is housed on the pond.
When boiler is just started working, but controller control damper and the controlled door opening that communicates with the external world, controller control controllable check valve and the controllable check valve that communicates with the external world are opened, but waste gas effluxes from the damper that communicates with the external world after being arranged the inlet pipe road, this moment, waste gas was pressed very little, along with boiler enters normal operating conditions, but the damper that controller control communicates with the external world turns down but Close All not exit passageway is corresponding, simultaneously according to baroceptor detect pressure control the startup and the rotating speed of pressurization fan with being directly proportional, guarantee the pressurized fan extraction of waste gas and pressurize, flowing through, row advances wet scrubber behind the air door again, behind dust-removing sulphur removing function, be discharged into atmosphere; When boiler is flame-out, but but controller control damper close, open fully with the extraneous damper that communicates, allow the exhaust of boiler nature stop working; Pipeline produced negative pressure water and recharges when the unidirectional air door before the deduster can prevent that boiler is flame-out.
The invention has the beneficial effects as follows: but because damper and pressue device be housed, can force dedusting and flame-out naturally according to the working condition of boiler in clarifier, and water recharges can prevent effectively that boiler from stopping working the time, more can satisfy technology and market demands.
