Description
Technical field
The present invention relates to a kind of combined filter.
Background technology
In order to reduce operation of air conditioner energy consumption, modern building and removable little space strengthen air-tightness, decrease ventilation, add the extensive use of organic synthesis material in decoration and equipment apparatus, indoor VOC gas is caused to distribute in a large number, severe exacerbation indoor air quality.Due to the seal of building and the finiteness of space, the concentration of indoor pollutant is usually high than outdoor, even seriously exceeds the countries concerned's standard.Time that people spend in indoor average every day is than much longer in outdoor, so indoor air quality all can produce direct impact to the physical and mental health of people, comfort and operating efficiency.In closed environment, the effective measures improving indoor air quality adopt air cleaning unit to purify air exactly, reduce pollutants in air concentration in health allowed band.Only reduce indoor pollution substrate concentration, simultaneously when indoor environment is in thermal comfort zone, people just can feel comfortably cool health.
Air-conditioner purifier conventional at present all uses relative to a certain particular space usually, and volume is bigger than normal, is not easy to carry, and does not have the function of good detection control indoor environment, and is not very high to the purification efficiency of low concentration pollutant, and service life is partially short.The physicalchemical structure performance of the scavenging material that air-conditioner purifier uses affects purification efficiency, to a great extent so select suitable material for core extremely important.In filter core reply room air, main low concentration pollutant has good removal effect, has certain removal effect, and requires little so that energy-conservation to the flow resistance of gas, good moldability to ubiquitous light concentration gas pollutant.
Filter comprises usually from the medium by removing some pollutant the air of filter.A kind of medium for this filter is active carbon.Active carbon is effective for removing multiple pollutant from gas flow.Active carbon typically has many microporositys surface, is easy to like this by pollutant attachment on these surfaces, thus by contaminant removal from gas flow.
The producer of some air treatment systems carries out modification to the active carbon in its filter, to improve the pollutant that medium activity removes some type.In the first instance, the individual particles that the producer improves activated carbon filter media makes it contain KI.The charcoal particle of modification like this has some characteristic improved of removing known contaminant formaldehyde, and it obtains formic acid by catalysis formaldehyde, finally obtains carbon dioxide and water.But the active carbon containing KI is only applicable to specific humidity range.In second example, the individual particles that the producer improves activated carbon filter media makes it contain potassium hydroxide, potassium hydroxide is applicable to removing sour gas from gas flow, and for example, low molecular weight carboxylic acid is as butyric acid, valeric acid, isobutyric acid, isovaleric acid and caproic acid.In the 3rd example, the individual particles that the producer improves activated carbon filter media makes it contain phosphoric acid, and phosphoric acid is applicable to removing alkaline gas from gas flow, such as rotten (fourth two) amine, indoles, scatol, methylamine, trimethylamine and pyrimidine.
In existing technology, application number is 93222819, the patent of invention that name is called " a kind of air cleaning unit processing organic exhaust gas ", mainly for the organic pollutant that concentration is higher, improper to light concentration gas.Application number is 94207705, name is called the patent of invention of " high-efficient absorbent carbon filter for air purificator ", it is short to there is service life in this clarifier scavenging material used, and the shortcoming that detergent power is limited is not fine to the clean-up effect of indoor low concentration pollutant.Also have application number to be 97104191.1 in addition, the patent of invention that name is called " indoor air-purifier ", the ozone mainly utilizing glow discharge to produce and anion are to realize the harmless and purification of indoor environment.
200610171826 disclose a kind of active carbon filter processing the gas flow containing different relative humidity, and gas flow is polluted by least one formaldehyde, sour gas and alkaline gas.Filter comprises most activated carbon granules mixed on charcoal bed filter.Manganese dioxide and potassium hydroxide in part particulate load.KI and potassium hydroxide in another part load.Phosphoric acid in Part III particulate load.Different piece carries out catalyze oxidation of formaldehyde and other pollutant under different humidity.Any carboxylic acid that potassium hydroxide primary chemical formaldehyde adsorption produces.And provide a kind of method of filter process gas flow.
Bentonite is large at China's reserves, application widely, its specific area is large, heat endurance is high, absorption property is good, is a kind of environmental-protection adsorption agent of potential high efficiency low cost, but bentonite also exist swellability comparatively large, be difficult to the shortcomings such as sedimentation, for solving the problem of practical application, prepare that a kind of adsorption effect is higher, settling property good and cheap Bentonite Clean Water Reagent becomes the focus of research.In prior art, acrylamide and bentonitic compound are almost all developed as a kind of high water absorption composite material, and the preparation method of this composite mainly contains solution polymerization process, via Inverse-Phase Suspension Polymerization, radiation polymerization.1. solution polymerization process refers to the polymerization (Ji Hong gradually etc. in " in the research containing bentonitic Crosslinked Super Absorptive Polyacrylamide ") reaction monomers and initator etc. being dissolved in and carrying out in suitable solvent.The low conversion rate of this preparation method's monomer, polymerization speed is slow; The dry difficulty of product; Easily form block gel in reactor and be difficult to process; 2. via Inverse-Phase Suspension Polymerization take organic solvent as decentralized medium, and water-soluble monomer, under suspending agent and strong agitation effect, is dispersed into suspension aqueous phase droplets, and initator is dissolved in the polymerization carried out in aqueous phase droplets.(at " synthesis and characteries of Sodium Polyacrylate/montmorillonite composite high-water-absorptivresin resin ", CN1769191 is used for bentonite base composite material of water treatment and preparation method thereof to Zhang little Hong etc.).Its disadvantage is complex technical process, and the post processing of product is more difficult, must remove the solvent of low molecule reactant and entrained with in product, will reclaim a large amount of decentralized media simultaneously.3. radiation-initiated polymerization method is the method (Li Hong etc. are at " super water-absorbent polyacrylamide/montmorillonite composite material mechanical property Quality Research ") using gamma-radiation or the copolyreaction of ultraviolet light irradiation initiation grafting.But because ray radiant energy is high, for the poor selectivity of chemical reaction, easily there is side reaction, thus limit the range of application of the method.
