Description
The invention belongs to liquid and do that release agent separates the particle of disperse from gas, air or steam and the chemical cleaning method of waste gas.
The basic task of industrial enterprise's Air Pollution prevention and control is an emphasis control flue dust.Reduce contained flue dust, carbon dioxide and other content of harmful gas in the boiler coal smoke.At present the technology that adopts only is conceived to dedusting, machinery type bag-type dust for example, and technology such as the electrostatic precipitation of physics mode are to the harmful matter that is gaseous state SO for example
2, CO, CO
2HC and BaP still do not have effective control techniques at present.Lopa Nationality semi-annular jade pendant power plant spends 3,000 ten thousand dollars to introduce desulfurization method of limestone-gypsum, not only invests expensively, every kilowatt of electricity will of and annual be paid and produce one ton of gypsum, is difficult for handling, thereby is difficult to promote.Single with regard to dedusting, at present the mechanical type dedusting technology to particle less than 10 microns floating dust also intractable.The exhaust gases of internal combustion engines that also has means of transportation to produce outside the boiler smoke also is a kind of flue gas of atmosphere pollution, does not also have a kind of effective purification technics measure at present.Because various flue gases can not get purifying, the pollution of atmosphere situation of China is very serious.Country is administering the flue gas air conservation as a scientific research problem.
The objective of the invention is to propose the simple and easy to do new method of a kind of combined dust-eliminating, purification and three kinds of technical requirementss of noise reduction.Solve the smoke pollution problem more up hill and dale.
Content of the present invention be with air by air distributing device aeration in liquid, adopt the mode dedusting of liquid filtering air, in liquid, be dissolved with middle mixture simultaneously.Mostly be acid at harmful matter in the air, middle mixture can be selected the alkali matter preparation for use.Make in the process of air undercoating liquid filtration, contained harmful matter and middle mixture close reaction in taking place, and reaction product is deposited in the filtrate.Airborne noise is a kind of form of energy, also can be absorbed by filtrate through filtrate.Air is through reaching the requirement of dedusting, purification and noise reduction simultaneously after the filtrate.The present invention is under being used for other situation during Purge gas, and the Substance P H value to be clean that contains in the pH value of filtrate and the gas to be clean is opposite, realizes the purpose that purifies to contain reaction in producing.
Characteristics of the present invention are tangible.The invention belongs to the wet chemical technology, be different from electrostatic method and bag dust-removing method, essential difference is also arranged with existing Wet techniques such as soaking method and moisture film methods.Wet techniques such as traditional water-bath or moisture film are familiar with gas and water on technology grace is thought relation is to be auxilliary based on gas, water.For example soaking method, water become to drip shape shower air.Obviously water is in a disadvantageous position.The situation of moisture film method changes to some extent, and moisture film becomes moisture film to water droplet like one " wall ", fastens in the pass of water and gas, is intended to increase the force of water.The equipment of moisture film method often is provided with the multiple tracks moisture film, also is this thought.But do not change the correlation based on gas yet, moisture film is many, and equipment is also complicated, makes corresponding raising with running cost.One boundary of failing to break through inwardly all the time at traditional Wet technique is in the relation that fundamentally changes gas and water, and making water is that master, gas are auxilliary.And substantive distinguishing features of the present invention just is being this.Aeration process in technological scheme of the present invention and the water in the oxygen disperser of oxygen supply technology is similar, but from technological thought essential distinction is arranged also.Oxygen supply generally is the biochemical processing that is used for sewage or waste water except that aquaculture in the water, and purpose is to handle water, and the objective of the invention is to handle gas.
In wet processing in the past, the obstacle people break through water and air to close is to be one of reason of main boundary with gas, are that people think at large as if being the main resistance that can produce the obstruction air current flow with water.Can make burner produce " sulks " phenomenon on flue gas is handled is difficult for solving.Burner adds blower unit in practice, and for example the big chimney that diminishes gradually of induced draught fan or internal diameter is seen everywhere, and all is the technical measures that are used for increasing exhaust power.Adopt relative measures, also can overcome water, for example add induced draught fan and play air pump the resistance that exhaust produces.
The technology that the invention has the advantages that is simple, and running cost is low, is easy to popularize.In wet processing in the past, not only gas will flow, and water also will flow, and no matter sprays or forms moisture film, all wants consumption of power and a large amount of water.The operational system that water will be arranged in the equipment, technology is also corresponding complicated.Among the present invention, in to close liquid motionless, only flue gas moves with the mode of aeration, implementing measure can significantly be simplified.The consumption of power and water can reduce, and fortune pipe expense reduces.Equipment is also simple.
Embodiments of the invention divide two contents, close liquid preparation in the first, and it two is designs of air distributing device.
The inventor adopts soda ash, i.e. Na in practice
2CO
3Close liquid in the obtained aqueous solution conduct, obtain comparatively ideal effect.Flue gas is at Na
2CO
3After the aeration, the dust that wherein contains is stayed in the solution, SO in the aqueous solution
2, CO, CO
2, HC and BaP gas or dispersed granules and Na
2CO
3Close reaction in the generation and also stay in the solution, the bubble that discharges from liquid level be have certain moisture content purification gas.For moisture content is not lost because of volatilization, the inventor has added vegetable and animals oils in solution makes the liquid saponification and hinders water evaporates.The inventor thinks because soda ash is easy to get and the corrosion of nontoxic nothing, is a kind of desirable middle mixture.The vegetable and animals oils source is abundant, and non-corrosiveness is desirable saponification liquor.Also can select the saponification liquor of other type for use.When utilizing the present invention to purify other gas, just need pH value and other chemical property according to material to be clean, centering mixture and saponification liquor are selected.
In the filtrate preparation, solution concentration is relevant with treatment effect and life time.The inventor is with water: soda ash: vegetable oil is 100: 17.8: 5 a ratio preparation filtrate, is unsaturated state at normal temperatures.
Invent big wide vehicle exhaust and the flue gas processing equipment of boiler of artificial use amount, adopt the technological scheme that the present invention proposes two kinds of forms.Fig. 1 is vehicle exhaust noise reduction, purifier, and Fig. 2 is Figure 1A-A sectional drawing, and Fig. 3 is boiler smoke dedusting, purifier, and Fig. 4 is Fig. 3 B-B sectional drawing.Illustrate: tail gas or smoke inlet pipe 1, gas distributing chamber 2, in close device 3, aeration tube 4, solarization air cap 5, outlet pipe is used for and closes the liquid mouth of pipe 6 in the input, in close liquid 7, in close chamber 8, gas distributing chamber's diapire 10, boiler 11, flue 12, outage 9, induced draught fan 13.
