Description
Technical field
The present invention relates to a kind of film separating air purifier, particularly use membrance separation screening mechanism separation gas and solid particle, with the air purifier of purifying contaminated air.
Technical background
In haze weather phenomenon, what people paid close attention to the most surely belongs to PM2.5.PM2.5 and PM10 refers to inhalable particles pollutant, and they are two important Detection of Air Quality indexs.This kind of particulate matter contains various chemical composition, is also the transmitting carrier of the microorganism such as antibacterial, virus simultaneously.
Air purifier in the market has the purification of mechanical filter screen, electrostatic precipitation purification, anion fine-purification etc. technically with regard to the purification of solid contaminant.And from purifying the aspect of gaseous contaminant, have again the principle such as adsorption cleaning and photochemical catalytic oxidation.All there is respective shortcoming in these purification techniques, such as machinery filter screen purifies shorter for service life with the filter element of adsorption cleaning, needs periodic replacement, which results in the increase of use cost.Electrostatic precipitation purifies and anion fine-purification for another example, easily produces secondary pollution, and the manufacturing process of depurator is complicated, and manufacturing cost is higher.
PM10 and PM2.5 refers to that aerodynamic diameter is less than or equal to 10 microns and the particulate matter of 2.5 microns respectively, and the hollow-fibre membrane that can design pore size filter utilizes screening mechanism can filter out these particulate pollutants.And hollow-fibre membrane can clean, can which solve, with Reusability, the shortcoming that common filer element type air purifier needs to change filter element.Photocatalytic oxidation activity adsorbent charcoal also has self-cleaning function, it is possible to decrease the use cost of user.As the core component filtered, hollow-fibre membrane is relatively low with composite active adsorbent carbon cost, which overcomes the shortcoming that part existing air purifier cost is high.
A class is also had now to utilize hollow-fibre membrane to purify the depurator of air, such as " based on membrane separation technique and the air purification method of water washing cleaning and device " that number of patent application is 201310542752.6, hollow-fibre membrane in this depurator uses the mode of film chamber air inlet, solid granulates accumulation of pollutants is at film inner chamber, need to regularly replace new membrane module, cause the increase of use cost.Number of patent application is " a kind of blowing-type air purifier " of 201320046259.0 for another example, do not consider the pore size filter of hollow-fibre membrane, and the moisture blocking fenestra in air, and dust adsorption membranous wall is difficult to the problems such as cleaning, and filter method is single, it is impossible to filter gaseous contaminant.
Summary of the invention
It is an object of the invention to combine two kinds of purification styles, utilize hollow-fibre membrane screening mechanism to cross the solid contaminant in air filtering, utilize composite active adsorbent carbon to filter gaseous contaminant, simple in construction and can be with Reusability.
For achieving the above object, the technical solution used in the present invention is: hollow fiber film type air purifier, including blower fan, composite active adsorbent carbon, hollow fiber film assembly.The outer porose netted shell of assembly is as the air inlet of depurator, and membrane module, composite active adsorbent carbon box, blower fan are tightly connected successively.Air is entered by outside fiber film component only, is finally discharged by blower fan through filtering.
Described blower fan for turbo-dynamo blower fan or other centrifugal fan of negative pressure can be provided, be positioned at above equipment, air inlet is tightly connected with composite active adsorbent carbon box, provides controlled underbalance for hollow fiber film assembly.Having dust disposable box below described hollow fiber film assembly, the solid granulates being blocked in outside by hollow-fibre membrane can settle and concentrates in disposable box.The Hollow-fibre membranes material itself used has antistatic and hydrophobic performance, it is possible to use the hollow-fibre membrane of surface-coated nano coating, nano coating act as antistatic and hydrophobic.When using the hollow-fibre membrane in 1-2 Mm filter aperture, may filter that the solid contaminant of the large-sizes such as PM2.5 and PM10, and can guarantee that the gas of maximum, by efficiency, reduces the load of blower fan and shortens the depurator working time.It addition, may be used without 0.1-1 Mm filter aperture, or the hollow-fibre membrane that pore size filter is less.Now, may filter that some antibacterials in air and other smaller particulates emissions, filter effect is more preferable, but gas is weakened relatively by property.Through hollow-fibre membrane filtered air, under the negative pressure of blower fan drives, enter composite active adsorbent carbon box, fall gaseous contaminant at composite active adsorbent carbon box inner filtration.Pure air through filtering is discharged by the air outlet of blower fan side.Described composite active adsorbent carbon box, hollow fiber film assembly, dust disposable box be can disassembled simply device, facilitate disassembly, cleaning.Described fan outlet and air delivery duct there is quieter material, absorbable part fan noise.
Beneficial effects of the present invention: purify particulate pollutant efficiency high, this hollow-fibre membrane of bright employing, have the advantages that specific surface area is big so that depurator has bigger purification area under less volume.Can life-time service, use membrance separation physics screening mechanism, and anti-static function can prevent dust adsorption on film surface, hydrophobicity can prevent in air moisture blocking fenestra, these all make hollow fiber film assembly in use not have spillage of material.Economy, present configuration is simple, low cost of manufacture；Hollow-fibre membrane is capable of washing, extends service life, thus reduces use cost.Non-secondary pollution, physical cleaning principle, purification process does not produce secondary pollution.Filter solid particle size range is big, and doughnut membrane aperture can design, and the aperture of 1 microns may filter that the particulate pollutant of each aerodynamic sizes such as PM2.5 and PM10.

Detailed description of the invention
As it is shown in figure 1, after depurator energising, motor 1 works, drive 12 turbofan to rotate, the air in body is got rid of 13 air outlets, close, 2,6, fan work district and surface, the activated carbon adsorption functional areas generation negative pressure that housing is constituted.
Further, the suction function that blower fan produces, on 51 hollow fiber film threads, drives the air in 513 hollow-fibre membrane chambeies to discharge.
As shown in Figure 4, Figure 5, driven by air negative pressure, the external world does not crosses air filtering and is entered into outside membrane module by 3 hole pattern shape shells, gas can design after fenestra enters 513 hollow-fibre membrane chambeies through 511 hollow-fibre membranes, gaseous contaminant is filtered again through 6 composite active adsorbent carbon boxes, being discharged by turbofan, the air now discharged is for crossing air filtering.
Now, solid particle is blocked in outside 512 antistatic behaviours and hydrophobic film body, owing to having hydrophobicity and antistatic behaviour, 511 hollow-fibre membranes can design fenestra and will not be blocked by the moisture in air, are blocked in the solid granulates pollutant outside film and also will not adsorb on 512 antistatic behaviours and hydrophobic film body surface.
Further, solid granulates pollutant, through the screening of hollow-fibre membrane, will be settled down to 4 dust collecting function districts.
41 dust disposable boxes can be taken off, it is simple to cleans.
Having 53 hollow fiber film assemblies to fix latch in 52 hollow-fibre membrane fixing devices, convenient unblock is dismantled, and 5 hollow fiber film assemblies can be taken off Reusability after cleaning.
