Description
Technical field
The present invention relates to a kind of wash mill, be specifically related to a kind of hermetic type air cleaning wash mill.
Background technology
Air cleaning is meant and removes gas componant of being polluted by harmful material in the surrounding air and foreign material, makes surrounding air return to clean process.Air cleaning is handled and can be divided into overall situation improvement and two aspects of subenvironment processing.It is main governing measure that overall situation is administered the energy-saving and emission-reduction that mainly guide energetically with present country and support, has made significant headway; Yet, to the supervision and the improvement of subenvironment air quality, now for various reasons, also can reach desirable environmental requirement far away, and being people, subenvironment the most often contacts and lives in place wherein.With people's life feeling and healthy in close relations, be the very important place of air cleaning.But the difficulty to little child's air pollution purified treatment is big; Require highly, air-polluting pollutant is disorderly huge and complicated, the input of in addition paying attention to limited science and technology and market a little less than; The means and the method for administering are slightly inadequate; Now, Along with people's is to the lifting of quality of life requirement and the enhancing of health perception, and the market demand has presented rapid growth.
So-called " subenvironment " is meant the particular range of people's work, life; It can be an airtight space; As: indoor, community, place, shopping centre, public place, workshop, enclosed type market, compartment, cabin, cabin etc. and print, spray paint, rubber industry workshop, agricultural production booth, indoor livestock rearing field, exhibition room, station, hospital etc. and work and movable closely-related place, all belong to the category of subenvironment.Also can be the specific zone of a slice, as: the zone that sewage treatment plant is peripheral, Biohazard Waste Disposal is peripheral, the chemical plant is peripheral, the cement plant is peripheral and all contaminative flue dust, dust descend slowly and lightly etc.The quality of subenvironment air quality is influence life and the health and the comfort that are operated in people wherein directly.Such as overrich such as the sulfur dioxide in some environment, hydrogen sulfide, ammonias; The perhaps severe overweight of poisonous and harmful substance such as formaldehyde, radon gas, benzene etc. in the air of local environment; And dust or to humans allergic's material in the local environment, or even problem such as virus, germ is too much.
To the subenvironment air cleaning mainly from deodorizing, remove the evil, three kinds of fields of dedusting set about, the technological means of main flow has the following aspects at present:
1) adsorption filtration method
Through selecting for use some that the medium property material or the film of adsorption capacity are arranged; There are materials such as flavor, harmful, poisonous, dust to carry out adsorption filtration to airborne; Its material commonly used is like active carbon, volcano float stone, diatomite, polyvinyl lactam etc., and hole, burr or the current potential property of utilizing its adsorbent self is to airborne dirt molecule, foul smell molecule, carry out absorptive collection to harmful molecule of human body and dust, pollen, chemical agent droplet etc.Can reduce the concentration of poisonous in the air, harmful, odorant and dust.Yet the adsorption filtration method is the process of a variable, and the initial stage effect is obvious, but saturated gradually along with sorbing material; Adsorption capacity descends; Obvious variation can appear in effect, can not reach the stable of filtration result, and the cost of replacing sorbing material is also higher relatively.
2) cladding process
Use some aromatic odors to cover, cover former scent of, make the people alleviate acceptance level indecency smell from sense organ.Though cladding process is obvious for the environmental effect of handling, and is applicable to the large tracts of land operation.But can not eliminate airborne poisonous and hazardous material, can not fundamentally improve the environmental quality of air, and have the use of some chemical aromatic possibly also can increase dustiness air.
3) decompose neutralisation
Utilization ozone and ultraviolet etc. by force oxidizing gas or chemical agent and physical means such as ultrasonic wave, microwave, heating, pressurization, distillation, extraction or burning to airborne harmful molecule decompose, processing such as neutralization, fragmentation, poisonous and hazardous gas molecule is changed into nontoxic synthetic molecules or gas on-gaseous molecule.Decomposition method is the comparatively desirable method that current air ambient is administered.The decomposition synthetic method needs the support of certain medium form, could accomplish decomposition or degraded to the predetermined substance molecule.As: the molecular reaction of gas and gas needs collision of molecules and the molecule reaction time from new formation; And the reaction of gas-liquid needs the assurance of time and contact area too, with regard to the technological means that can recognize at present, no matter is spray or spraying, and time and area all are very limited.Therefore the means of used various decomposition reactions all exist technical sophistication, high, the weak effect of cost, and technology is popularized difficult problems such as difficulty is big.
Airborne pollutant is to exist with three kinds of forms basically:
1) gas molecule form; Be to produce in some organic chemistry evolutions or the inorganic materials process; As hydrogen sulfide, methane, hydrogen fluoride, carbon monoxide, carbon tetrachloride, ammonia nitrogen etc. all to human body and life pernicious gas, some also is attended by strong penetrating odor.The removal of these materials needs through means such as chemical reaction synthetic reaction such as neutralization or oxidation and networkizations.
2) molecule form; Like flue dust, dust, dust 、 bioxin (group's property thing), graphite powder, mineral powder, segment of fiber, organic matter material group, biological cell chip, microorganism corpse etc.; These finely ground particles or chemical substance group, the affinity that can be through water and the effect of absorption affinity are retained in the water or in the organic solvent; And can be through the special chemical composition that in water or organic solvent, applies, to its decompose, processing such as neutralization, oxidation, reduction.Even if the material that temporarily can't handle also and combined in again among the liquid material, provides convenience for shifting or deeply handling.
3) live body form material; Like virus, germ, small life entity, pollen, worm's ovum, living microorganism, mushroom spore, allergin source etc.; To these dirts; That the best way is exactly in water, to add is antitoxin, antibiotic, sterilization, sterilized pharmaceutics deactivate processing to it, and the corpse after will handling is taken in water.
Based on above-mentioned three kinds of reasons; We go over the air purifying process that institute use and grasps having used for reference us, and our domestic and international advanced technology and the scheme about air improvement that can recognize, pass through conscientious research and contrast; We find, through the mode of washing.Can the airborne pollutant of major part be retained in the water, simultaneously, we can incorporate materials such as some lytic agents, nertralizer, catalyst, oxidant or absorption, displacement, flocculation in water, and change can be with most of pollutant removal in the air.To also some water-fast materials, its major part also can be dissolved in the organic solvent, so we begin to consider the feasibility of water-washing technique.
In sum, the preferably effective method of air cleaning is a decomposition method, but decomposition method need solve three difficult problems:
1) time of contact: just individual molecule and molecule time of reacting and whole harmful substance are participated in the time that the quantity of reaction is accomplished;
2) contact area: harmful substance is decomposed or degrades in the air, must contact with its material of decomposing, degrade, and the probability of contact is bigger, the quantity of reaction is just many more, and it is thorough more that pollutant is just removed;
3) contact method: no matter be nertralizer or disinfectant; The environment that all needs a load; This environment is best with liquid, because a lot of medicament is can directly dissolve in water or the organic solution, when the harmful substance of required processing in the air is introduced in the solution that is dissolved with medicament; Just can carry out multiple collection fully, take in, react, remove harmful purpose to reach.
So time, area and method have determined the success or failure and the effect of decomposition reaction, if can in an equipment platform, accomplish decomposition, degraded, absorption, dissolving multiple technologies means are integrated, can effectively promote treatment effect.Integrated means are many more, and its particular functionality is also just strong more, the pernicious gas of some intractable, and it is easy also will to become.
The air cleaning wash mill incorporates through the small bubble that air is broken into certain specification and rotates in the aqueous solution that seethes; Utilize the time of staying and the linear movement in stop process of bubble in water or organic solvent; Cause self replacing of the interior air of bubble to obtain air and long-pending maximization and the generalization of water engaging surface; Let in the water contained materials such as oxidant, displacer, distintegrant and synthetics contact fully and react, to realize its washing, replace and to pay off etc. air in the bubble with harmful substances in air.Such washing can be gone out washings such as the particle in the specific gas, suspension, dust, fiber, cell debris, pollen, bacterium; Be utilized in simultaneously add in the water to the specific gas molecule decomposes, the oxidant of synthetic or oxidation reaction, synthetics, catalyst etc. change toxic and harmful in the air molecule or strand; Cut short or grafting; Reach the change molecular conformation, produce new innocuous substance, omnidistance nontoxic, harmless.
Spray column is the air washing means of now generally taking, and scrubbing tower generally is made up of 8～10 meters high tank bodies, and spray or sprayer unit are set on the top of tower; The air of required processing is blown into by the bottom of tower; Air upwards flows, and water droplet or droplet are done the movement of falling object downwards, and water droplet forms collision, contacts with air in tower; Adsorb, dissolve, take in or react (adding necessary nertralizer, reactant etc. in the water) thereby produce, reach clean result air.But the excessive velocities that water droplet or droplet descend,, land the time (10 meters of the tank bodies of scrubbing tower are high) of water droplet is merely 1.42 seconds, and a lot of washing reactions is not also accomplished, process just is through with.Water droplet and droplet are rectilinear motion in scrubbing tower, the exchange area that can form is limited and fixing, because time and exchange area are all limited, so effect and washing cleanliness are also limited.Because the gas-liquid contact is the straight line contact, therefore many airborne pollutants fail to touch mutually, mix with the water droplet that streaks, and a lot of characteristic materials is can be difficult by affine glutinous the staying of hydrone, such as airborne heavy metal ion, poisonous and hazardous gas molecule etc.
No matter be scrubbing tower or spray-on process; Its water consumption all is very huge, so after contaminated air is purified, all must be equipped with a complete sewage disposal; Air-treatment and sewage disposal addition, engineering cost and cost all are heavier burdens.
