Description
Technical field
The present invention relates to air purifying process field, especially a kind of multi-layer intercrossed fountain--cold-warm type washing air purification device.
Background technology
At present, the air pollution that the mankind depend on for existence is on the rise.The discharge capacity of life, traffic, process gas is always high.The frequency that haze weather occurs is more and more higher, and coverage rate is more and more wider.Badly influence people's normal work and life.Local air purification techniques has become the instrument of the most useful interim pollution remission.Air purifying process is long-standing, in constantly exploring, people are according to the self-characteristic of air pollutants, and having adopted various technology to carry out local air purification, these technology mainly comprise: light catalytic purifying, anion fine-purification, ozonization, multiple filtration dedusting, electrostatic precipitation, disinfection by ultraviolet light, clean cluster ion technology, HEPA filtration method, active carbon purifying etc.In recent years, the theory of air washing had caused people's interest and attention.Imitate after the Nature rain the air abnormal pure and fresh phenomenon that becomes, air washing technology has been compared a lot of advantages with traditional air purifying process.But still immature with regard to current existing air washing purification techniques, therefore fail be used widely on the market.
With regard to current disclosed air washing purification scheme, be substantially all to adopt to take washing link as main, the comprehensive purifying scheme forming in conjunction with other purification techniques.And just wash link itself, the method for washing of taking, can be divided into two classes substantially: a class is water-bed purification; One class is spray cleaning.Water-bed purification is to adopt air to be pressed into the bottom, after empty G&W is mixed, by the buoyancy of air, from water-bed emersion water, then is extracted and emits, and reach purification object.Spray washing, is by the sprinkling of water, air to be washed away, and reaches purification object.The mode that the bottom purifies air, seems a kind of purification ratio method more thoroughly, in fact, goes over, and is not in the imagination.First, if water-bed gas outlet is very large, be forced into so water-bed agglomerating the emerging of air meeting, it is exactly our viewed bubble of emerging at ordinary times, because the density contrast of empty G&W is apart from larger, objectionable intermingling, air can wrap up agglomerating emerging because of the cohesion of self, is so just difficult to reach the object of purification.If water-bed venthole is very tiny, the air plankton before purification is easy to stop up injection well, even stops up air duct.And in a lot of schemes, the water that is used for purifying air, can not purify at any time, is easy to cause secondary pollution.If with circulating water, the one, waste water resource, the 2nd, be subject to the spatial limitation of position, water source.
About spray washing purification method, the spray washing link design in a lot of water washing cleaning schemes is too simple, and the washing frequency that unit air capacity is accepted is very low, and seem by water and rinsed, be in fact to have walked individual interlude, do not reach clean-up effect.Some adopts the scheme of Multi-layer sprinkling, but the method for layering and Air Flow route are reasonable not, can not make full use of space, water, electric resources.
Summary of the invention
In order to overcome many defects of existing water washing cleaning air method, realize and save water source, make full use of the device space, significantly promote clean-up effect, this case has adopted ' multi-layer intercrossed fountain-cold-warm type washing air purification device '.
' multi-layer intercrossed fountain--cold-warm type washing air purification device ' mainly contains spraying box and storage tank two parts form.Spraying box is an enclosure space being formed by the spraying box shell that leaves air inlet and gas outlet, air outlet is equipped with air exhauster, in the inner side of the front and back panel of spraying box shell, be fixed with the shower plate of interlaced arrangement, shower plate two ends respectively with spraying box shell both sides panel inside airtight combination, the staggered structure of shower plate of spraying box shell front and back panel inner side has formed the shaped form air migration passage of a multilayer.Respectively below each shower plate, with the parallel horizontal direction of spraying box shell front and back panel, the several showers of parallel installation.Storage tank is arranged on the lower end of spraying box, and the airtight connection of spraying box, and storage tank inner upper end is communicated with by sewage filter net and spraying box bottom.Storage tank divides water storage tank for sewage water and water purification storage tank two parts, between the two, by screen pack, is communicated with.Electronic refrigerator and electronics heat-producing machine are housed respectively on water storage tank for sewage water and water purification storage tank casing.Water storage tank for sewage water internal memory is placed with adsorbent.Spraying box and storage tank both sides external are provided with flow pipe and water pump, and flow pipe lower end is communicated with clear water storage tank, and upper end and shower are communicated with.
When this air cleaning unit uses, according to temperature condition, if thermic anomaly, first unlocking electronic refrigerator (or electronics heat-producing machine), the water of storage tank is adjusted to after uniform temperature, restart water pump, water in filtered water tank is divided and sent to each shower by flow pipe, when all showers all spray after water smoke, restart air exhauster, under the effect of air exhauster, when wind enters spraying box from air inlet, first pass through first airstrainer, contaminant filter larger in air is fallen, air is again through after the washing away of the multiple tracks water smoke curtain of every one deck afterwards, again after second air filtration net filtration, from air outlet, blow out.Rinsed the water smoke of air, from each above shower plate down one deck shower plate conflux, while finally arriving spraying box bottom, first, after first sewage filter net, flow into water storage tank for sewage water, in water storage tank for sewage water, pass through adsorption cleaning and the precipitation of adsorbent, afterwards, water enters clear water storage tank through second screen pack more again, clear water is sent into shower by water pump by flow pipe again, has so just formed a complete circulation.
Designed ' multi-layer intercrossed fountain--the cold-warm type washing air purification device ' of this case has the following advantages.
1. the multi-layer intercrossed spray process that adopted and shaped form air migration path, can maximally utilise device resource, allows air fully stand spray washing, reaches best purification effect.The spraying layer being staggered installation of, the function that can not only carry spray, has also played barrier effect, that is and, spraying layer and separation layer unite two into one, and have greatly saved space, have sketched the contours of dexterously the shaped form migration path of air.
2. there is very strong function dilatancy.The air capacity of each unit is from entering spraying box to going out spraying box, will be through a lot of spraying layers, during by each spraying layer, pass again several roads cascade, the air of each unit like this, cover spray link, will be through tens times, the up to a hundred times frequencys even more and water collision is rinsed, its clean-up effect is well imagined.This spray structure can increase easily the number of plies of spray and extend the distance of air migration, increases flexibly the cascade road number of spray in same layer, or lengthening, the overstriking shower scale of construction, and increases washing time and the frequency of air; Improve whole air purification effect.The increasing of the spray structure scale of construction, will certainly expand water consumption, and the increase of water consumption can and strengthen pump working horsepower and realize by overstriking flow pipe.Therefore the method that, function dilatancy and simple structure make this air washing flexibly both suitable applications, in indoor air cleaning facility, is conveniently applied to again large-scale industrial gas emission and processes.In addition, the dilatancy of function is also embodied in, and can, outside spray link, increase neatly other purification method.Before or after entering clarifier at air, other treatment facilities such as screen pack are set as required neatly.
3. spray structure is scientific and reasonable, avoids repeated contamination.First, air enters from spraying box bottom, and from top out, and shower water flows from top to down, and such reverse geometry is the most rational cleaning process.That is, water flows from top to down, through one section of flushing, become messy, and air enters just during to bottom from the bottom of spraying box, and the messy air of just coming in runs into the flushing of dirtier water.Air, through becoming gradually after spray irrigation the early stage in spraying box bottom totally, while then going to spraying box top, runs into the shower water that spraying box top is cleaner.Not only can not form repeated contamination like this, can also guarantee and improve clean-up effect.Secondly, aqueous vapor shunting, current have a style of one's own, and form a complete purge line.Water is in spraying box from top to bottom from level to level after flushing out air, be mingled with the dirt washing away and collecting the water storage tank for sewage water flowing to below spraying box, before entering storage tank, first through multistorey strainer mesh, filter, just enter afterwards water storage tank for sewage water, water in water storage tank for sewage water again after absorption, precipitation etc. purify, by the screen pack higher than 1/3rd places, storage tank bottom, enter clear water storage tank again, clean water in clear water storage tank, by flow pipe, be sent to spraying box top, shunting enters in shower again, starts the spray process of a new round.Spray circulation limit, waterside purifies, and use is all clean water at every turn.Like this, not only can keep the cleaning of shower water, also avoid using running water and the waste that causes.
4. the electronic refrigerator of installing on storage tank casing and electronics heat-producing machine, can change the water temperature in storage tank by electronics system temperature as required.So not only can regulate air themperature by water temperature, play the thermoregulatory effect of air conditioner, can also make room air cause local temperature difference and promote the Air Flow in whole space.Avoid the purification blind area of freely not causing due to Air Flow, therefore improve whole clean-up effect.
5. for indoor air cleaning unit, the air inlet structure that has indoor and outdoors and deposit, the air inflow of indoor air admission hole is 2 to 3 times of outdoor air admission hole air inflow.Like this, both can guarantee purification speed and the cleanliness factor of room air, can also constantly cover outdoor new air, guarantee that oxygen fills into, can effectively guarantee again the regulating effect of indoor air temperature.
6. the airstrainer of air inlet and the installation of air outlet place, and the filter bores of air outlet place screen pack is less than the filter bores of air inlet place screen pack, can effectively strengthen the clean-up effect to air.
