Description
Technical field
The present invention relates to environment and protect technical field, especially a kind of flue dust absorber eliminating coal, oil firing flue dust.
Background technology
Along with social development, the raising of national life level and manufacturing industry are fast-developing, the mankind are to coal, wet goods demand for energy sharp increase, the problem of environmental pollution brought therefrom is increasingly severe, the a large amount of atmosphere pollution of gas of flue dust and greenhouse effect, serious threat is brought to human health, if do not prevented and not treated, its consequence will be more serious, therefore countries in the world pay attention to environmental pollution prevention and control all especially, with multiple flue dust prevention and treatment method, traditional coal fired boiler smoke abatement and dust control cloth bag dry method filter dirt, due to it, easily blocking and smoke medicining dust-removing effect are good and be eliminated, currently mainly carry out smoke abatement and dust control with spray and spraying and moisture film method, this wet method smoke prevention and dust control method effect is better, greatly reduce sulfur and coal particles, the cigarette come up is no longer that black smoke billows, become white cigarette.This white cigarette still contains micronic dust particle and greenhouse gases, environment is still had pollution.Existing spray, spraying and moisture film method device therefor volume are big simultaneously, and structure is complicated, and water consumption is big, and operating cost is high.Vehicle exhaust is also the important sources of atmospheric pollution, and mostly the method administering vehicle exhaust at present is with ternary catalyzing unit, although can eliminate part harmful gas and big powder, but a considerable amount of harmful gas and microgranule can not be removed.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the flue dust absorber that a kind of simple in construction, operating cost are low, smoke medicining dust-removing effect is good.nullThe purpose of the present invention is realized by following technical proposals: the present invention includes motor、Liquid holding box、Liquid holding box lid、Lead cigarette straight tube，The discharging tube of switch it is provided with bottom liquid holding box body，Liquid holding box top is provided with liquid overflow pipe，Liquid holding box bottom is provided with the feed tube of switch，It is provided with bottom liquid holding box and leads that cigarette straight tube installing hole and conduit straight tube are fixing to be connected，It is characterized in that: the liquid holding box lid corresponding with leading cigarette straight tube is installed with motor，Motor shaft stretches into inside liquid holding box lid and fixes with smoke guiding cover and is connected，Smoke guiding cover covers in leads above cigarette straight tube，Its infraoral is lower than liquid overflow pipe transverse tube lower wall 10-30cm，Smoke guiding cover outboard tube is blind pipe，In smoke guiding cover、Serpentine pipe group is installed between outboard tube，Serpentine pipe bottom tube wall be provided with several to dozens of diameter be 3mm liquid mist hole，Aqueous slkali is filled in liquid holding box，Liquid holding box lid is provided with that Freeing Pipe installing hole and Freeing Pipe are fixing to be connected，Freeing Pipe is sleeve pipe，Its little mouth of pipe top communicates with liquid holding box top，Bottom is stretched in aqueous slkali.
One can be set bottom described liquid holding box and lead cigarette straight tube installing hole, it is possible to set and several lead cigarette straight tube installing hole, the quantity such as installation lead cigarette straight tube, corresponding liquid case lid is provided with equal number of motor and smoke guiding cover.
The present invention is under the idle state of smoke guiding cover, just with smoke guiding cover for boundary, is divided into by whole device and leads flue and two enclosed areas of liquid case.When smoke guiding cover rotates, effect due to centrifugal force, just utilization is led cigarette serpentine pipe and is made the mutual fusion of two enclosed areas, thus continuously the flue dust of smoke guiding cover near top is sent into serpentine pipe, serpentine pipe bottom spray hole mixes with flue dust after being constantly atomized by calcium hydroxide liquid, and it is as follows to enter aqueous slkali generation chemical reaction:
CO2+H2O=H2CO3
H2CO3+Ca(OH)2=CaCO3↓+2H2O
SO2+H2O=H2SO3
H2SO3+Ca(OH)2=CaSO3↓+2H2O
2NO2+H2O+Ca(OH)2=Ca(NO3)2+H2O+H2↑
Particulate matter in flue dust is deposited on containing in aqueous slkali solution.Not with CO, NO, H of the substance reaction in aqueous slkali2Overflow from Freeing Pipe, enter coal combustion equipment by appendix and process, under the high temperature conditions:
2CO+O2=2CO2↑
2NO+O2=2NO2↑
2H2+O2=2H2O
Due to smoke guiding cover constantly reduce near lead in flue flue dust, the gas pressure intensity led in flue of this end constantly reduces, and the other end constantly produces hot cigarette, and hot cigarette is in operation and is gradually lowered temperature, more low closer to smoke guiding cover temperature, and simultaneously pressure is also more low.In airtight container, fluid always flows to pressure lower ground side from the place that pressure is high, so flue dust just constantly flows to smoke guiding cover headroom, keep normal operation, when flue dust is by serpentine pipe, owing to the micropore of its underpart takes aqueous slkali water droplet out of, the rapid atomization mixing with flue dust when high speed rotating, there is chemical reaction, nuisance in major part flue dust is made to be removed, a small amount of flue dust is also had to be removed by the aqueous slkali in liquid holding box, a small amount of harmful gas not reacted with aqueous slkali is sent combustion apparatus back to by Freeing Pipe and the appendix that is connected and is again combusted into easily processed gas.Through experimental test, after this device processes, do not produce any smog, from the above, it may be appreciated that it is an object of the invention to realize, and excellent.
