Abstract

The invention discloses a multifunctional chimney which comprises a tower top arranged at an upper layer, a tower body arranged at a middle layer, a tower bottom arranged at a lower layer, a flue gas inlet and a flue gas outlet, wherein a porous adsorption plate is arranged in the tower top arranged at the upper layer from top to bottom, a plurality of spray throwers consisting of sprinklers and a porous plate are arranged in the tower body arranged at the middle layer, a suspended matter layer and a clear water layer are arranged in the tower bottom arranged at the lower layer from top to bottom, and the flue gas inlet, an overflow pipe and a blow-off pipe are arranged on the side face of the tower bottom. The invention treats flue gas by utilizing the effects of adsorption and segmentation of the clear water layer and the suspended matter layer arranged at the tower bottom, the effects of sprinkling, washing, stripping, atomization and the like of the porous plate and the sprinklers in the tower body and the effects of adsorption, drying and purification of the tower top, has the advantages of simple structure and low manufacture cost, can efficiently removing smoke and dusts and carry out desulfuration on the flue gas and is suitable for fileds such as combustion furnaces, boilers, smelting furnaces, cupola furnaces, kilns, chemical industrial furnaces and the like.

Description

Multifunctional chimney

Technical field:

The present invention relates to a kind of chimney, specifically is a kind of multifunctional chimney of environmental protection.

Background technology:

Present most of combustion apparatus all is to be fuel with the coal, and existing chimney is just smoked and smoke evacuation, simply flue gas is sent to high altitude discharge, diffusion, and this discharging modes are brought very big pollution to environment.Be the harmful substance in removing smoke, generally take to be provided with cleaner, so both increased cost of investment, increased floor space again.For solving these technical problems, announced a kind of " gas cleaning chimney stack " of the patent No. 200620050411.2 at Chinese patent, the bottom of this chimney is the lime pond, middle lower floor is the spray district that several floor shower nozzle are installed, the upper strata is equipped with shutter, and this chimney has certain limitation to the height of chimney, must use high-pressure pump that limewash is atomized, structure is comparatively complicated, and limewash strengthens the corrosion of equipment simultaneously.

Summary of the invention:

It is more simple to the objective of the invention is a kind of structure, and low cost of manufacture is applicable to combustion furnace, boiler, smelting furnace, furnace cupola, kiln and chemical industry stove, can effectively carry out the multifunctional chimney of smoke abatement and dust control, desulfurization to flue gas.

In order to achieve the above object, technical scheme of the present invention is:

At the bottom of multifunctional chimney of the present invention includes the tower of the body of the tower in cat head, middle level on upper strata and lower floor, gas approach and exhanst gas outlet, in the cat head on upper strata, from top to bottom arrange the porous adsorption plate, in the body of the tower in middle level, be furnished with the spray thrower that many group spray equipments and porous plate are formed, suspension layer and clear water layer from top to bottom are set at the bottom of the tower of lower floor, and the side at the bottom of tower is provided with flue gas inlet pipe, overflow pipe and blow-off pipe.

Adopt technique scheme that following beneficial effect is arranged:

The clear water layer of flue gas at the bottom of entering tower by the flue gas inlet pipe under the effect of air blast, flue gas contacts with water, coarse granule falls into the water, the heat that while flue gas itself has makes water obtain heating, temperature raises and produces a large amount of water vapours, flue gas is cut apart by the suspension layer when leaving the clear water layer, fully contact sulphur in the flue gas of back with the suspension laminar surface, harmful substance major parts such as dirt are adsorbed, flue gas with move upward after water vapour mixes, the humidity of flue gas increases, the flue gas that contains water vapour enters body of the tower, form water membrane in the body of the tower during aperture of the shower water of spray equipment on the porous plate of flowing through, the flue gas tunicle when passing through moisture film that contains water vapour is washed, the flue gas that contains water vapour is subsequently sprayed by spray equipment again, washing, film is washed and is atomized, the dustiness of flue gas, sulfide, nitrogen oxide, carbide further reduces, when spray liquid adopts alkalescence, desulfurized effect is better, enter the porous plate of cat head through the flue gas after porous plate and the spray equipment processing, adsorb, dry and purify, be discharged into atmosphere after thoroughly removing the harmful substance in the flue gas.

Description of drawings:

Accompanying drawing is the cross-sectional schematic of multifunctional chimney of the present invention.

Among the figure: 1, cat head, 2, body of the tower, 3, at the bottom of the tower, 4, exhanst gas outlet, 5, the porous adsorption plate, 6, spray equipment, 7, porous plate, 8, the suspension layer, 9, overflow pipe, 10, blow-off pipe, 11, the clear water layer, 12, the flue gas inlet pipe.

The specific embodiment:

The present invention is described in further detail below in conjunction with accompanying drawing, but be not construed as limiting the invention.

Multifunctional chimney as shown in drawings, include at the bottom of the tower of the body of the tower 2 in cat head 1, middle level on upper strata and lower floor 3, on the cat head 1 on upper strata, exhanst gas outlet 4 be set, cat head 1 is interior by arranging multiplayer porous adsorption plate 5, in the body of the tower 2 in middle level, be furnished with the spray thrower that many group spray equipments 6 and porous plate 7 are formed, suspension layer 8 and clear water layer 11 from top to bottom are being set in 3 at the bottom of the tower of lower floor, 3 side is provided with flue gas inlet pipe 12, overflow pipe 9 and blow-off pipe 10 at the bottom of tower.

Claims

1. multifunctional chimney, at the bottom of including the tower of the body of the tower in cat head, middle level on upper strata and lower floor, gas approach and exhanst gas outlet, it is characterized in that: in the cat head on upper strata, from top to bottom arrange the porous adsorption plate, in the body of the tower in middle level, be furnished with the spray thrower that many group spray equipments and porous plate are formed, suspension layer and clear water layer from top to bottom are set at the bottom of the tower of lower floor, and the side at the bottom of tower is provided with flue gas inlet pipe, overflow pipe and blow-off pipe.
