Abstract

The invention discloses a household filter for filtering inhalable particles in air. The filter comprises an outer shell and a filter vat, wherein the outer shell is provided with an air inlet and an air outlet; the filter vat is arranged in the outer shell; one end of the filter vat is sealed and the other end of the filter vat is fixed at the air inlet end of the outer shell; and the filter vat is communicated with the outdoors. The household filter is characterized in that the air inlet on the outer shell is communicated with the outdoors and the air outlet on the outer shell is communicated with the indoors; and the filter vat is made of microporous ceramic, and a fan and a pressure alarm are additionally arranged, wherein the fan is positioned in the outer shell and is fixed at the air outlet end of the outer shell, the pressure alarm is fixed at a position of the outer shell and is not positioned at the ends of the air inlet and outlet, and the position of the pressure alarm is close to the end of the air inlet. The household filter has high efficiency for filtering the inhalable particles in the outdoor air, strong practicality and operability, low cost and long service life and is convenient to use in families.

Description

A kind of in the air of family expenses the pellet stripper
Technical field
The present invention provide a kind of in the air of family expenses the pellet stripper, belong to life environmental protection dedusting technology field.
Background technology
Particle diameter can be called pellet (being called PM10 or floating dust again) through the particle of respiratory tract entering human body less than 10 μ m in the atmosphere, mainly is made up of organic matter, sulfate, nitrate and earth's crust dvielement.Pellet flies in the air because of in industrial dedusting, being difficult for being eliminated for a long time.Wherein, In pellet, account for more than 60%, particle diameter less than the particle (being called PM2.5 again) of 2.5 μ m owing to can 100% be deep into bronchiole and alveolar; Maximum to human harm, thereby more merit attention, indoor one of the controlled major pollutants of answering become.
Current, fine particulates is removed more effectively electrostatic precipitation, shaped Venturi dedusting and bag-type dusting.There is following common ground in these three kinds of methods: 1. removing object mainly is the high-temperature flue gas in the industry, generally not towards room air; 2. required apparatus structure is complicated, cost is high and very difficult miniaturization, is inappropriate for family expenses; 3. the removal efficiency to pellet reaches as high as 92%.Therefore, exploitation removes the problem that technology is domestic and international research in urgent need of strengthening towards the room air pellet practicability of family expenses, not only has huge economic benefit, and has potential environmental benefit and social benefit.
Diatomite is the silicastone that ancient times, the remains deposit generated of diatom, and main chemical is a silica, and there is the aperture in countless gaps its inside, and porosity is high to reach 80%~90%.The diatomite ceramic element that diatomite is formed through high temperature sintering more than 1200 ℃ has that light weight, porosity are big, adsorptivity and characteristics such as permeability is strong, chemical property is stable; Its internal penetration passage is not only the duct that forms between the diatomite particle; And the inner micropore of diatomite particle also can and diatomite particle between the duct converge, form huge pore network.The more important thing is that the average pore size of diatomite ceramic element can effectively stop passing through of subparticle at 0.15 μ m~0.50 μ m, main at present as efficient industrial filter membrane, have important development and application values.
Summary of the invention
The objective of the invention is to, provide a kind of in the air of family expenses the pellet stripper, to solve the problems of the technologies described above.
The technical problem that the present invention solved can adopt following technical scheme to realize: comprise the shell body that is provided with air inlet, air outlet; Be arranged in the shell body, the end sealing other end is fixed in shell body air inlet end and with the outdoor filter vat that communicates; It is characterized in that: the air inlet on the shell body communicates with outdoor, and air outlet communicates with indoor; Filter vat adopts micropore ceramics, sets up blower fan and pressure alarm, and wherein blower fan is positioned at shell body and is fixed on the air opening end of shell body, pressure alarm is fixed in shell body non-on the housing of air port end and its position near the air inlet end.
Described in the air of family expenses the pellet stripper, the material of shell body can be metal or engineering plastics.
Described in the air of family expenses the pellet stripper, the cross section of shell body can be circle or polygon.
Described in the air of family expenses the pellet stripper, the material of filter vat is the diatomite ceramic element, and the average pore size of diatomite ceramic element is at 0.15 μ m~0.50 μ m.
Described in the air of family expenses the pellet stripper, the cross section of filter vat can be circle or polygon.
Described in the air of family expenses the pellet stripper, pressure alarm adopts Pressure gauge or pressure sensor.
Described in the air of family expenses the pellet stripper; Its operation principle is: during dust removal and filtration; Be fixed in the positive reversal chamber of blower fan of shell body air opening end and bleed; The outdoor air that contains pellet is just got into by air inlet and is fixed in the filter vat of shell body air inlet end; Airborne pellet is adsorbed on the filter vat inwall because of the average pore size of particle diameter much larger than the diatomite ceramic element, and the outdoor air of filtering pellet is just delivered to indoor via blower fan; Treat the work certain hour; Pellet thickening on the filter vat inwall stops up the filtering holes on the diatomite ceramic element, and the residing indoor pressure of blower fan this moment diminishes, and filtering efficient reduces; Treat that the residing indoor pressure of blower fan is reduced to certain value; Pressure alarm begins to report to the police, and the blower fan counter steer is outdoor supplies gas, and the pellet on the filter vat inwall comes off and blown to outdoor.One-period is accomplished, and goes round and begins again.
The present invention compared with prior art has following advantage: (1) the present invention adopts diatomite ceramic element filtering pellet, and filtering efficient is more than 98%; (2) internal diameter of filter vat of the present invention and length controlled can be according to the sizes of interior architecture area, the appearance and size of design filter vat; (3) the diatomite ceramic element is an inorganic material, and convenient sources is with low cost, long service life; (4) the present invention is just changeing filter dirt, is reversing and take off dirt by blower fan, and practicality and workable is convenient to family and is used.
