Description
Technical field
The present invention relates to a kind of wash mill, be specifically related to a kind of hermetic type purification of air wash mill.
Background technology
Purification of air, refers to and is removed by the gas componant of harmful Substances Pollution and foreign material in surrounding air, makes surrounding air return to clean process.Purification of air process can be divided into overall situation to administer and subenvironment process two aspects.Overall situation improvement mainly, has been made significant headway for primary abatement means with the national energy-saving and emission-reduction guided energetically and support at present; But, for supervision and the improvement of subenvironment air quality, now for various reasons, also can reach desirable environmental requirement far away, and subenvironment is people the most often contacts and live in place wherein.With the life feeling of people and healthy in close relations, it is the very important place of purification of air.But it is large for the difficulty of little child's air pollution purified treatment, require high, air-polluting pollutant Pang is disorderly complicated, in addition the input paying attention to limited science and technology and market is more weak, the handy root canal preparation administered shows slightly not enough, now, the lifting required quality of life along with people and the enhancing of health perception, the market demand presents rapid growth.
So-called " subenvironment " refers to 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 the closely-related place of activity, all belong to the category of subenvironment.Also can be the specific region of a slice, as: the region etc. that sewage treatment plant's periphery, Biohazard Waste Disposal periphery, chemical plant periphery, cement plant periphery and all contaminative flue dust, dust descend slowly and lightly.The quality of subenvironment air quality directly affects life and the health and the comfort that are operated in people wherein.The such as overrich such as sulfur dioxide, hydrogen sulfide, ammonia in certain environments, or poisonous and harmful substance is as the severe overweight of formaldehyde, radon gas, benzene etc. in the air of local environment, and dust or to humans allergic's material in local environment, or even the problem such as virus, germ be too much.
For subenvironment purification of air mainly from deodorizing, remove the evil, dedusting three kinds of fields set about, the technological means of current main flow has the following aspects:
1) adsorption filtration method
By selecting some the medium material having adsorption capacity or films, adsorption filtration is carried out to the materials such as taste, harmful, poisonous, dust that have in air, its conventional material, as active carbon, volcano float stone, diatomite, polyvinyl lactam etc., utilizes hole, burr or the current potential of its adsorbent self to the dirt molecule in air, foul smell molecule, carries out absorptive collection to the deleterious molecular of human body and dust, pollen, chemical agent droplet etc.The concentration of poisonous in air, harmful, odorant and dust can be reduced.But adsorption filtration method is the process of a variable, initial performances is obvious, but saturated gradually along with sorbing material, adsorption capacity declines, effect there will be obvious change, can not reach the stable of filtration result, and the cost changing sorbing material is also relatively high.
2) cladding process
Use some aromatic odors to cover, cover original smell, make people alleviate the acceptance level to indecency smell from sense organ.Though cladding process is obvious for the environmental effect of process, be applicable to large area operation.But the poisonous and hazardous material can not eliminated in air, fundamentally can not improve the environmental quality of air, and there is the use of some chemical aroma agent also may can increase dustiness to air.
3) neutralisation is decomposed
Process such as using the Strong oxdiative gas such as ozone and ultraviolet or the physical means such as chemical agent and ultrasonic wave, microwave, heating, pressurization, distillation, extraction or burning to decompose the deleterious molecular in air, neutralize, be broken, changes into nontoxic synthetic molecules or gas on-gaseous molecule by poisonous and hazardous gas molecule.Decomposition method is the ideal method of present air environmental improvement.Local behavior method needs the support of certain medium form, just can complete the decomposition to predetermined substance molecule or degraded.As: the molecular reaction of gas and gas, needs intermolecular collision and molecule from the new reaction time formed; And the reaction of gas-liquid, no matter need the guarantee of time and contact area too, with regard to the technological means can recognized at present, be spray or spraying, and time and area are all very limited.Therefore the means of used various decomposition reaction all also exist the difficult problems such as technical sophistication, cost are high, weak effect, and the universal difficulty of technology is large.
Pollutant in air is exist with three kinds of forms substantially:
1) gas molecule form, that some organic chemistry develop or produce in 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 is also attended by strong penetrating odor.The removal of these materials, needs by neutralizing or the means such as the reaction of the chemical reactive synthesis such as oxidation and network.
2) molecule form, as flue dust, dust, dust, bioxin (group's property thing), graphite powder, mineral powder, segment of fiber, organic material group, biological cell chip, microorganism corpse etc., these finely ground particles or chemical substance group, the affinity of water and the effect of absorption affinity can be passed through, be retained in water or in organic solvent, and the special chemical composition by applying in water or organic solvent, it decomposed, neutralizes, be oxidized, the process such as reduction.Even if the material that temporarily cannot process, also and combined among liquid material again, for transfer or go deep into process and provide conveniently.
3) live body form material, as virus, germ, small life entity, pollen, worm's ovum, living microorganism, mushroom spore, allergin source etc., for these dirts, the best way adds antitoxin, antibacterial, sterilization exactly in water, sterilized pharmaceutics carries out deactivation process to it, and is taken in water by the corpse after process.
Based on above-mentioned three kinds of reasons, we used for reference we go over the air purifying process that uses and grasp, and we can recognize both at home and abroad about advanced technology and the scheme of air treating, through conscientious research with contrast, we find, by the mode of washing.Pollutant in most of air can be retained in water, meanwhile, in water, we can incorporate the materials such as some lytic agents, nertralizer, catalyst, oxidant or absorption, displacement, flocculation, and change can by pollutant removal most of in air.To also some water-fast materials, its major part also can be dissolved in organic solvent, so we start the feasibility considering water-washing technique.
In sum, purification of air preferably most effective method is decomposition method, but decomposition method need solve three difficult problems:
1) time of contact: namely individual molecule and molecule carry out the time that quantity that time of reacting and overall harmful substance participate in reacting completes;
2) contact area: in air, harmful substance is decomposed or degrades, must with can decompose, its material of degrading contacts, the probability of contact quantity that is larger, reaction is more, pollutant just removal more thorough;
3) contact method: no matter be nertralizer or disinfectant, all need the environment of a load, this environment is best with liquid, because a lot of medicament can directly dissolve in water or organic solution, be dissolved with in the solution of medicament when the harmful substance processed required in air is introduced in, just can carry out multiple collection fully, take in, react, remove harmful object to reach.
So time, area and method determine success or failure and the effect of decomposition reaction, if decomposition, degraded, absorption can be completed in an equipment platform, to dissolve multiple technologies means integrated, effectively can promote treatment effect.Integrated means are more, and its specific function is also stronger, and some very unmanageable pernicious gases, it is easy also will to become.
Purification of air wash mill incorporates in the aqueous solution rotating and seethe by small bubble air being broken into certain specification, utilize the time of staying of bubble in water or organic solvent and the linear movement in holding process, cause self transposition of air in bubble to obtain maximization that air and water engaging surface amass and generalization, the materials such as oxidant contained in water, displacer, distintegrant and synthetics are allowed to contact fully with the harmful substance in air and to react, to realize its washing to air in bubble, replace and pay off.Particle in specific gas, suspension, dust, fiber, cell debris, pollen, bacterium etc. can be washed away by such washing, utilize simultaneously add in water carry out decomposing for specific gas molecule, to synthesize or the oxidant, synthetics, catalyst etc. of oxidation reaction changes molecule or the strand of toxic and harmful in air, cut short or grafting, reach change molecular conformation, produce new innocuous substance, omnidistance nontoxic, harmless.
Spray column is the air washing means generally taked now, scrubbing tower is generally made up of the tank body of 8 ~ 10 meters high, spray or sprayer unit are set on the top of tower, the air of required process is blown into by the bottom of tower, air flows upwards, water droplet or droplet do the movement of falling object downwards, and water droplet and air are formed and collide, contact in tower, thus generation is adsorbed, dissolves, takes in or is reacted (adding necessary nertralizer, reactant etc. in water), reaches the clean result to air.But the excessive velocities that water droplet or droplet decline, land the time (tank body 10 meters of scrubbing tower is high) of water droplet is only 1.42 seconds, and a lot of washing reactions does not also complete, and process just finishes.Water droplet and droplet are rectilinear motion in scrubbing tower, and the exchange area that can be formed is limited and fixing, and because time and exchange area are all limited, therefore effect is also limited with washing cleanliness.Because gas-liquid contact is straight contact, the pollutant therefore in many air fails to touch with the water droplet streaked, mix, and a lot of characteristic materials difficultly to be stayed by affine the sticking of hydrone, the heavy metal ion in such as air, poisonous and hazardous gas molecule etc.
No matter be scrubbing tower or spray-on process, its water consumption is all very huge, so after purifying contaminated air, all must be equipped with a complete sewage disposal, air-treatment is added with sewage disposal, and engineering cost and cost are all heavier burdens.
