Abstract

A full-enclosed wet desulfurizing purifier for eliminating the smoke dust and harmful gas such as SO2 and NO2 of industrial boiler and effectively preventing the secondary pollution of sewage features that three basic dusting mechanisms of water sprinkling, autoexciting and water curtain filtering are sequentially arranged to increase dusting and desulfurizing efficiency. In addition, circular settling tube, valve and precipitating pond are used to form a full-enclosed structure for removing dust, preventing the sewage from secondary pollution.

Description

Wholly-enclosed wetting desulphurization smoke purifier

The present invention relates to a kind of environmental protection equipment, is that a kind of Industrial Boiler that is used for is eliminated flue dust, SO ₂, pernicious gas such as NOx and can effectively prevent the multi-function boiler flue gas cleaner of sewage secondary pollution.

At present, the deduster of domestic boiler adapted major part is cyclone dust collectors, multi-tube dust cleaner, and they all can not purify the SO in the flue gas ₂, pernicious gas such as NOx.Though electrostatic precipitator, pulsaire collector efficiency of dust collection are than higher, cost is too high, and power consumption, power consumption can not purify the pernicious gas in the flue gas greatly equally.Though wet scrubber such as moisture film, venturi type energy purifying harmful gas is discharged a large amount of subacidity waste water and is caused secondary pollution, also has floor space big simultaneously, shortcomings such as cost height, operating maintenance inconvenience.

It is little that purpose of the present invention just provides a kind of volume, cost is low, purification efficiency is high, water consumption is few, pollution-free, the method uniqueness of collection smoke abatement and dust control, desulfurization, dehydration a tractor serves several purposes, handsome in appearance, floor space is little, uses is easy to maintenance, the multifunctional fume purifier of suitable China's actual conditions.

Technical scheme of the present invention is that spray cleaning, self-excitation purification, water film filtering are purified three kinds of purification mechanisms and concentrate in proper order in the clarifier integral body, its concrete scheme is that Wholly-enclosed wetting desulphurization smoke purifier is by square cavity, the outlet cone on square cavity top, the taper pond of bottom, the self water feeding dosing tank of taper pond one side, the circular sediment tube of bottom, taper pond, the start or stop valve and the sludge deep detector at circular sediment tube middle part, the bracing frame of the sedimentation basin of circular sediment tube bottom and bottom, taper pond constitutes.Wherein sedimentation basin top is bullet, and the bottom is a square cavity, and the bottom is sealed with steel plate.In one side, sedimentation basin square cavity bottom, establish mud and wash in a pan door clearly.

Wherein, circular sediment tube in bottom, taper pond and following part-structure adopt utility model patent, totally-enclosed multi-cyclone auto-excitation type flue gas cleaner, the patent No. 952080621.

Technical scheme of the present invention also comprises: on the inwall of the clarifier square cavity left and right sides, be fixed with shower, vertical clapboard, vertically every device plate bottom intensify the upper and lower cavity in chamber, moisture film sparge pipe, water are chewed and water fender etc.

Below in conjunction with accompanying drawing the present invention is described further.

Fig. 1 is a side view of the present invention.

Fig. 2 is a vertical view of the present invention.

Fig. 3 is a rearview of the present invention.

Wholly-enclosed wetting desulphurization smoke purifier is by square cavity [1], the outlet cone [2] on square cavity [1] top, the taper pond [3] of bottom, the self water feeding dosing tank [4] of taper pond [3] one sides, the circular sediment tube [5] of bottom, taper pond [3], the start or stop valve [6] and the sludge deep detector [7] at circular sediment tube [5] middle part, the sedimentation basin [8] of circular sediment tube [5] bottom and the bracing frame [9] of bottom, taper pond [3] constitute, wherein sedimentation basin [8] top is bullet, the bottom is a square cavity, and the bottom is sealed with steel plate.Be provided with the clear Tao Men of mud [10] in one side, square cavity bottom

Wherein, on the inwall of clarifier square cavity [1] left and right sides, be fixed with shower [11] and vertical clapboard [12], vertical clapboard [12] bottom intensify chamber upper cavity [13] and lower chamber [14], moisture film sparge pipe [15] and nozzle [16] and water fender [17] etc.

When flue gas enters clarifier square cavity [1], the water that is located at import department upper end shower [11] spray under the fierce impact of air-flow, make water atomization and with the flue dust neutralization, when flue gas impact water fast and the time, force a large amount of harmful substances to fall into the pond.By the fourth flue gas high speed impact water surface, intensify and form water smoke once more intensifying chamber upper cavity [13] and lower chamber [14] chien shih water, flue gas purifies for the second time.When flue gas by intensifying after the chamber comes out, pass through the filtration of moisture film again.Flue gas is purified for the third time, the SO in the flue gas ₂Deng pernicious gas, then with add in advance and in alkali lye such as Ca (OH) ₂Reaction generates CaSO ₃, CaSO ₄The precipitation and remove.Take off gas behind the dirt through being fixed on the dehydration of the water fender [17] on square cavity [1] inwall, enter air-introduced machine, chimney and enter atmosphere by outlet cone [2] at last.

Claims

1. one kind by square cavity [1], the outlet cone [2] on square cavity [1] top, the taper pond [3] of bottom, the self water feeding dosing tank [4] of taper pond [3] one sides, the circular sediment tube [5] of bottom, taper pond [3], the start or stop valve [6] at circular sediment tube [5] middle part and the heavy degree of mud detector [7], the Wholly-enclosed wetting desulphurization smoke purifier that the precipitation ground [8] of circular sediment tube [5] bottom constitutes, wherein sedimentation basin [8] top is bullet, the bottom is a square cavity, the bottom is sealed with steel plate, be provided with the clear Tao Men of mud [10] in one side, square cavity bottom, it is characterized in that on the inwall of square cavity [1] left and right sides, being fixed with shower [11] and vertical clapboard [12], vertical clapboard [12] bottom intensify chamber upper cavity [13] and lower chamber [14], the moisture film sparge pipe [15] on vertical clapboard [12] right side, bottom and nozzle [16], in the vertical clapboard right side, the water fender on top [17].

2. described according to claim 1, Wholly-enclosed wetting desulphurization smoke purifier is characterized in that water spray, flue gas self-excitation, three kinds of udst separation mechanism of water film filtering form a kind of flue gas purifying method and concentrate in the clarifier integral body.
