Abstract

The utility model discloses a flue-gas cleaner which can eliminate harmful gases such as sulfur dioxide, etc., in fume. The flue-gas cleaner is composed of a gas access, a shower, a bell type regulating cover, a cyclone tube with wind deflectors, an overflow pipe, a reservoir, an outlet core tube, etc. The utility model can do first level sprinkling and two stage purifying to the fume, is provided with an overflow device, which has good purifying effect, can achieve the smoke gas emission standards of the one or two classes of nation, and can be used for the purification of boiler flue gases and vent gases with the other dust and flying materials.

Description

A kind of flue gas cleaner

The utility model relates to a kind of flue gas cleaner, especially has the flue gas cleaner that removes the pernicious gas device.

It is of a great variety that the flue gas cleaner that uses is gone up by society at present, variety of configurations, along with environmental requirement to improve constantly wet scrubber development very fast, but the water consumption that has causes the secondary sewage pollution greatly, the reservoir top that has do not have overflow mechanism use in liquid level covered by suspension easily, cause air-flow and liquid contact surface to reduce and influence the efficient of dedusting and elimination pernicious gas.

The purpose of this utility model provides a kind of purification efficiency height flue gas cleaner of the new structure of continuous operation for a long time again.

The utility model is realized by following manner, top at the clarifier tank body is provided with shower, smoke inlet is located at tank body top one side, outlet core wound packages is at the tank body center, its middle part is peripherally equipped with bell regulating the qi flowing in the channels cover, between regulating the qi flowing in the channels cover and the outlet core tube whirlwind tube that the louver wind deflector is installed on top is housed, between whirlwind tube and outlet core tube is vortex chamber, tank base is liquid storage tank and mud hopper, containing sweetening liq in the pond, overflow pipe is equipped with in the side, and liquid storage tank is linked to each other with the liquid level regulating tank by pipeline, with the overflow pipe sustained height on be provided with transparent window.

Operation principle of the present utility model comes downwards to the liquid storage tank liquid level for the flue gas that is entered clarifier by smoke inlet mixes outside bell-jar with shower spray liquid down earlier, and the impulse liquid level is sloughed flue dust and pernicious gas realization first class purification; Up along bell regulating the qi flowing in the channels cover inboard then, it is descending along the whirlwind tube to form swirling eddy by the louver wind deflector, the impulse liquid level carries out double purification once more, because centrifugal action liquid gas separates, flue gas after being purified is discharged by outlet through outlet core tube, and the liquid storage tank water level should be lower than bell regulating the qi flowing in the channels cover bottom, be higher than the whirlwind tube bottom, liquid level is by being located at a jar outer liquid level regulating tank control, and the suspension that liquid surface forms in the purification process is discharged by overflow pipe at any time, and sediment is emitted by the mud hole of mud hopper bottom.

The utility model is owing to carry out once spray to flue gas, secondary enters liquid surface fast and fully contacts with liquid, improved clean-up effect to flue dust and pernicious gas, being provided with overflow pipe in addition discharges the suspension of liquid level at any time, the shortcoming that the cleaning equipment that having solved has causes purification efficiency to reduce or interrupt because of the liquid level suspension guarantees the work of clarifier continuous high-efficient.Can reach 90-97% through test this clarifier efficiency of dust collection under nominal air delivery, desulfurization and NOx efficient reach 70-80%, reach GB13271-91 standard, meet country's one, two classes area environmental requirement.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is structure of the present utility model and operation principle schematic diagram.

Fig. 2 is that the A-A of whirlwind tube top louver wind deflector is to cutaway view.

Referring to figure one, the flue gas that is entered clarifier by smoke inlet (1) mixes with liquid under shower (7) spray, descending fast along tank body (9) inwall and bell regulating the qi flowing in the channels cover (2) outside then, the liquid level of impulse liquid storage tank (5), most of flue dust and pernicious gas are by liquid adsorption in the air-flow, air-flow rises along the bell regulating the qi flowing in the channels cover inwall and whirlwind tube (3) outside of being fixed in by support (13) on the tank body, the louver wind deflector (10) that passes whirlwind tube top forms swirling eddy along being advanced into vortex chamber (11) impulse liquid level once more under the whirlwind tube inwall, flue dust and pernicious gas double purification, gas and impulse liquid level form the liquid pearl and rise along outlet core tube (8) rotation, the liquid pearl is because centrifugal action sinks to liquid pool gradually, flue gas through purifying is discharged by outlet (6), the suspension that is suspended in liquid-pool surface is discharged from overflow pipe (4) at any time, the liquid level of liquid storage tank is by liquid level regulating tank (12) control of the outer band float of clarifier, and the dirt slag that is deposited in liquid storage tank bottom mud hopper (14) is regularly discharged by residual cake valve.

Whirlwind tube upper guide aerofoil can be 11-15, and its setting angle can become 12-25 degree angles with interior garden tangent line.

Can transparent window be installed at tank body and the same highly place of overflow pipe for observing the clarifier duty.

Claims

1, a kind of flue gas cleaner that constitutes by smoke inlet (1), tank body (9), liquid storage tank (5), exhanst gas outlet (6), it is characterized in that: smoke inlet is located at the tank body upside, bell regulating the qi flowing in the channels cover (2) is equipped with at outlet core tube (8) middle part, between regulating the qi flowing in the channels cover and the outlet core tube whirlwind tube (3) that louver wind deflector (10) is installed on top is housed, the whirlwind tube is vortex chamber (11) with outlet core tube bottom, tank base is liquid storage tank (5) and mud hopper (14), and liquid storage tank is linked to each other with liquid regulating tank (12) by pipeline.
