Abstract
The invention relates to a totally-enclosed environment-friendly chimney. The totally-enclosed environment-friendly chimney comprises a smoke dust gas treatment part and a smoke gas recovery part. The smoke dust gas treatment part is provided with an unground dust storage chamber, an overground inner-layer smoke dust treatment section, an overground outer-layer smoke dust treatment section and a smoke gas oxidization section. The inner smoke dust treatment section and the outer smoke dust treatment section are both provided with a smoke dust gas inlet, multiple layers of alternative protruding filter nets and a netted smoke dust gas outlet. The smoke gas oxidization section is provided with a smoke inlet, a netted platinum wire catalyst and a smoke outlet. The smoke gas recovery part is provided with a smoke gas leading pipe, a support, a smoke gas leading machine and a smoke gas absorption tower. The smoke gas absorption tower is provided with a smoke gas absorption chamber and a liquid storage chamber. The smoke gas leading machine conveys smoke gas into the smoke gas absorption chamber through the smoke gas leading pipe. Based on the backflow principle of alkaline fog sprayed out of a spraying head at the tower top and the oxidized smoke gas, the smoke gas absorption chamber guarantees that sulfur oxide, nitric oxide and carbonic oxide are completely absorbed under the effect of a porcelain net in the tower, and therefore zero pollutant emission is achieved.
Description
Technical field
The present invention relates to environmental protection totally enclosed type chimney.
Background technology
Existing chimney can not realize effectively controlling flue dust and fume treatment and discharge aspect in design, so that causes severe contamination to air.Although the chimney also had structurally improves, but still is faced with air-polluting baptism.
Summary of the invention
Technical problem to be solved by this invention is to provide environmental protection totally enclosed type chimney, realizes dust and is absorbed, low-carbon emission, reduce the pollution to air.
The present invention solves its technical problem by the following technical solutions.
Environmental protection totally enclosed type chimney, comprises dust processing section and off-gas recovery part.

The present invention is a kind of environmental protection totally enclosed type chimney, flue dust can be filtered completely by utilizing the screen pack of inside and outside double-deck dust treatment section, flue gas and air can be carried out mixing fully and oxidation by flue gas oxidation panel, utilize tower top shower nozzle to spray alkali mist with under the effect of countercurrent action porcelain net in tower of oxidation flue gas again through smoke absorption room, ensure that the oxide of sulfur oxide, nitrogen oxide, carbon is all absorbed, realize the zero-emission of pollutant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, environmental protection totally enclosed type chimney, comprise dust processing section and off-gas recovery part, dust processing section is provided with underground dust-storage chamber 1, on the ground, outer double-deck dust treatment section 2 and flue gas oxidation panel 3, by cleaning smoke dust duct to dust-storage chamber's periodic cleaning, dust enters into interior dust treatment section 7 from entering the dust mouth of pipe, through multiple filtration net 12, most of flue dust be filtered and fall into room in dust-storage chamber, part dust enters outer flue dust processing section 8 through interior dust treatment section dust mesh outlet 13, through multiple filtration net 14, the flue dust entered be filtered again again and fall into dust-storage chamber mistress, remaining flue gas enters flue gas oxidation panel 3 through outer flue dust processing section flue gas mesh outlet 15, flue gas enters through exhanst gas outlet and draws fume pipe 4 after three layers of platinum gauze 9 catalytic oxidation, flue gas is sent into smoke absorption room 10 fully contact under the effect absorbing indoor multilayer porcelain net 17 with the NaOH alkali mist sprayed from shower nozzle 16 by drawing turbine machine 5 from bottom to top and flue gas is absorbed completely again, finally discharge only containing N from smoke absorption tower upper end offgas outlet
