Abstract
The utility model discloses a coniform internal spiral water absorbing type water cleaning air purifier comprising a water cleaning dust section, an air purifying section and an air outlet section, wherein the air purifying section further comprises an air cleaner, an air flowing pipeline and a water tank; and the air cleaner is provided with spiral water absorbing equipment at the center of the air flowing pipeline of the water cleaning dust section. The utility model uses a water cleaning method to automatically clean an air inlet filter screen to remove dust. A motor which is provided with shafts at both faces can be adopted to drive a coniform internal spiral tube device by the underside and an impeller to blow upwards by the upside to realize dual purposes for one machine, save energy sources, and lower the cost. The utility model does not block the filter screen, does not pollute the purifying and sterilizing section and can ensure normal work for a long time. Particulate pollutants in the air are cleaned in a dust container and circulating liquid when passing through a water curtain, thereby the secondary population to the air purifier is avoided.
Description
Technical field
The utility model relates to the air cleaning unit technical field, particularly a kind of spiral water absorption type washing air cleaning unit that is used for public place and family's degerming dedusting.
Background technology
Air is one of people's important external environment condition of depending on for existence, along with industrialized development process, various industry, agricultural pollution, the destruction of natural environment, air pollution problems inherent is on the rise, present building, owing to consider the raising energy efficiency, adopt totally enclosed building structure more, greatly reduce the update efficiency of room air like this, the trend that IAQ now worsens.
Pernicious gases such as the formaldehyde that the finishing of Modern Family is left over, benzene, ammonia; Pet is cultured; Cigarette; The peculiar smell that wine and human body daily life produce, the pollen that flowers and trees produce, fungi etc., also air quality in broken ring casing, thereby, create a cleaning, aseptic, comfortable living space, people's health is seemed more important.
The preparation method of traditional cleaning equipment is: filter---filtration---and refilter anion, ozone, active carbon.This series products has play a part certain at the use initial stage to improving air quality; But, because due to its structure, must be often renew cartridge more, bring inconvenience and financial burden.And establish filter core has increased windage more, along with the increase of filtration time, causes the filter screen airflow obstruction, dust deposit, and bacteria breed causes secondary pollution to room air easily.
Traditional air cleaning unit is divided into three basic kind by cleaning principle:
1, mechanical filter formula
Employing contains the fiber or the bubble face of chemical material and highly dense material, is generally active carbon and high-efficiency fiber is two-layer, and shortcoming is that filter course blocks easily, uses a period of time after wind resistive big.
2, electronics is gathered formula
By high pressure, to give the electric membrane inside the rush stalk with dust particle, and make contaminated air pass through the electrode collecting board, positive negative absorption plays clean-up effect.Can regularly clean collecting board and recover purification efficiency.
3, in the anion and formula
Utilize the high voltage pin to produce anion, and blow out by motor (have even do not have motor) that anion makes it and common charged dust neutralization, the ground of falling after weight increases reaches clean-up effect, but because of itself does not absorb dust, therefore can cause the blackening of ambient body pollution, therefore this purification method gradually is eliminated.
Also there is same problem in hospital operating room (desinfection chamber) air-conditioning system at present.
Present most of hospital operating room (desinfection chamber) all adopts the interior changes in temperature of air-conditioning system conditioning chamber of fan-coil unit with fresh air, and its dust can not get effective removing.Also having the part air-conditioning equipment to adopt simply improves one's methods, install screen pack additional for the air outlet of air-conditioning, but because the air conditioner outlet distance is very short, wind resistance strengthens after installing screen pack additional, and the air-conditioning air output reduces, and has reduced efficient, destroyed air current composition, after the air block, indoor laying dust is constantly accumulation in air-conditioning, makes air-conditioning become new pollution sources simultaneously.
The main method of operating room (desinfection chamber) sterilization at present, sterilization is: remove indoor germ, virus extremely with medicine and ultraviolet lamp.In order to sterilizing ultraviolet lamps, its major defect is:
1, operating distance is short ,≤2m, and the sterilization operation time is long;
2, working life is short, and≤500-2000 hour, starting once equaled to use 3 hours;
3, ultraviolet ray can not the direct irradiation human body, man-machine can not same chamber, can not sterilizing when promptly working;
4, the volume of ultraviolet lamp is big, power consumption is big, and electromagnetic interference is arranged.
The high-grade operating room of part, desinfection chamber has been selected purification air-conditioning for use, has adopted the operation of full blast system, because it installs inconvenience, establish screen pack has increased windage more, and screen pack has caused the obstruction of filter screen air-flow along with the increase of time, dust deposit, suitable temperature has been aggravated bacteria breed, and room air is caused bigger pollution, increase the probability of disease and wound infection, the operation of full blast system makes the germ in each room intersect with air draught again easily and propagates.Advance one one, increased the possibility of disease infection in the hospital.Therefore existing air cleaning unit can not satisfy the needs of people to the air cleaning quality.
