Description

Oil filter-type indoor air cleaner

Technical field

The utility model relates to a kind of air cleaning unit for separating of fine particle in the air, especially relates to a kind of oily filter-type indoor air cleaner.

Background technology

Fine particle claims particulate, fine grained again.Particle diameter is used less than 2.5 μ m, i.e. PM2.5 sometimes less than 2 μ m(in the atmosphere) particle (aerosol).Though fine particle is content component seldom in the earth atmosphere composition, it has significant effects to air quality and visibility etc.

The fine particle particle diameter is little, is rich in a large amount of poisonous, harmful substances and the time of staying in atmosphere is long, fed distance is far away, thereby bigger to the influence of health and atmosphere quality.In February, 2012, State Council agrees that " ambient air quality " of the new revision of issue increased the fine particle monitoring index.On February 28th, 2013, national scientific and technical terminology validation board claims PM2.5 to intend definite designation to be " fine particle ".

Though fine particle is content component seldom in the earth atmosphere composition, it has significant effects to air quality and visibility etc.Compare with thicker Atmospheric particulates, the fine particle particle diameter is little, is rich in a large amount of poisonous, harmful substances and the time of staying in atmosphere is long, fed distance is far away, thereby bigger to the influence of health and atmosphere quality.Studies show that the more little harm to health of particle is more big.Fine particle can waft to place far away, so coverage is bigger.In addition, fine particle is bigger to the harm of health, because diameter is more little, the position that enters respiratory tract is more dark.The particle of 10 μ m diameters is deposited on the upper respiratory tract usually, be deep into bronchiole and alveolar that 2 μ m are following.Fine particle enters human body behind alveolar, directly influences the ventilatory function of lung, makes body be in anaerobic condition easily.And in a single day this fine particle enter alveolar, is adsorbed on to be difficult on the alveolar drop, and this absorption is irreversible.

At present, indoor PM2.5 administers the following method that mainly contains:

1, filtration method: comprise air-conditioning, humidifier, air freshener etc., advantage is the concentration of bright wet reduction PM2.5, though filter membrane can prevent the particle that 3 u m are above, but the air exchange rate reduces significantly, need regularly clean or replace owing to filter membrane simultaneously, use cost is higher, and prolongation in time, and clearance of particles efficient can descend thereupon.

2, water absorption method: ultrasonic atomizer, indoor cascade, pond, fish jar etc., can absorb airborne hydrophily PM2.5, shortcoming is to increase humidity, hydrophobicity PM2.5 can not effectively remove.

3, plant absorbing method: plant leaf blade has bigger surface area, can absorb pernicious gas and absorption PM2.5, and advantage is to produce favourable gas, and shortcoming is that absorption efficiency is low, and some plant can produce pernicious gas.

Summary of the invention

For overcoming the deficiencies in the prior art part, the utility model provides a kind of oily filter-type indoor air cleaner, can remove various fine particles in the room air quickly and efficiently, to solve the problem that use cost height, efficient are low, the hydrophobicity particle can not effectively be removed that prior art exists.

The technical scheme that the utility model technical solution problem adopts is: oily filter-type indoor air cleaner, this clarifier comprises oil vessel and loam cake, the described cap surface of going up has air admission hole and venthole, a brushless electric machine is equipped with in its inside, a miniature extraction fan that connects with described brushless electric machine main shaft, a taper centrifugal pump that driven by described brushless electric machine, this taper centrifugal pump oil-out place is provided with cross or the star blade that connects with described brushless electric machine main shaft; The opening that described oil vessel upper end has a gas outlet and connects with described loam cake, this oil vessel bottom is oil storage pool, one barrel-type casing of erectting is arranged in the middle of this oil storage pool, and this barrel-type casing side is provided with a wireway, and this wireway connects with the gas outlet of described oil vessel; Be provided with a tubular filter screen of erectting in the described barrel-type casing, be provided with a notched cone-shaped hood in this filter screen.

Operation principle: brushless electric machine drives the taper centrifugal pump vegetable oil in the cone-shaped hood is pumped up, by height rotating blades on the shell oil is thrown away equably, form the oily curtain of a ring-type, the oil curtain strikes and becomes one oil reservoir behind the container inner wall and run underneath in the oil storage pool, enter cone-shaped hood through the tubular filter screen, form circulation.Extraneous air is after the air admission hole of loam cake sucks, and in injection process, oil reservoir is airborne fine particle, floating thing, and dust flows in the oil storage pool after the impurity absorption such as smell.The air that purified is removed the residual mist of oil of possibility in the air by filter screen, exports from the gas outlet finally by wireway.

Beneficial effect: this air purifier purifying and recovering system air, principle is simple and reliable, and absorption affinity is far above water, and clean-up effect is fabulous, is better than the water absorption method greatly, and long perfomance life, and use cost is low, can be used for the room of 30-50 square meter.In order to filter better, can put some filter materials in the bottom, as ore, sponge etc., about every 6-8 week can be changed oil strain one time.
