Abstract
The invention discloses a formaldehyde gas absorber, belonging to the volatile-gas absorbing device. inside a container where a gas-inlet barrier and a gas-outlet barrier are arranged respectively in front of and behind a casing, a motor-driven fan is arranged behind the gas-inlet barrier; and from front to back, a physical absorption layer which is composed of active carbon and photocatalysis material and a formaldehyde-absorption and reaction layer which is formed by adding crosslinking agent and formaldehyde to sodium polyacrylatesorbent which is adopted as the sorbent carrier are arranged in turn. The invention, which is designed in this way, uses the fan in front to absorb to formaldehyde and other harmful gases in the environment actively; after passing through the physical absorption layer and the absorption and reaction layer, formaldehyde and other harmful gases are absorbed, reacted, and then the harm-removed gas is discharged. Thereby, the invention becomes the <active-absorption-type> product.
Description
Technical field
The present invention relates to the absorption plant of escaping gas, specifically is that a kind of formaldehyde dusty gas carries out the initiatively formaldehyde gas absorber of absorption.
Background technology
Formaldehyde is the very strong organic compound of a kind of volatility, and pollution level is higher, in daily life, clothing, food, firmly all may contact formaldehyde.Formaldehyde pollutes the generally attention that is subjected to society day by day.
Common formaldehyde pollutes, as producing or use industrial waste gas, vehicle exhaust and the photochemical fog of formaldehyde; Indoor formaldehydes such as construction material, indoor hardware fitting, furniture and smoking, cooking fume, fuel combustion pollute; The sterilization of hospital ward, instrument and equipment is dissected, that Pathology Lab is used for corpse, tissue specimen is fixing and preserve, and dental material is as the paraformaldehyde deactivator that is used for root canal etc.; Garment material is wrinkle resistant, shrinkproof, fire-retardant, adds formaldehyde in the auxiliary agent of stamp, dyeing; Food processing is soaked aquatic products etc. as formaldehyde.
Clearly stipulate indoor formaldehyde maximum permissible concentration 0.10mg/m3 in China's " IAQ standard " (GB/T 18883-2002).But, there is investigation to show that the content of most of indoor formaldehydes has all surpassed this standard, the concentration of formaldehyde in the room of more just having fitted up, even can exceed tens of times of standards.
Formaldehyde has material impact to health, it has the strong impulse effect to human body mucous membrane and skin, high concentration serious stimulation of respiratory tract and oedema can occur when sucking, causing that eye stimulates, headache. low concentration sucks and can cause continuing headache, unable, insomnia etc. and long term exposure can cause dermatitis, lung, dysfunction of liver, immunologic dysfunction, central nervous system influenced, also but the inhereditary material in the damaging cells is a suspect carcinogen.
At present, in China's public places sanitary standard regulation formaldehyde be one of must the survey project.
The improvement that PARA FORMALDEHYDE PRILLS(91,95) pollutes has many diverse ways, mainly contains chemical reaction method, biochemical decomposition method and absorption method etc.Wherein, absorption method have removal efficiency height, enrichment function strong, be difficult for causing advantage such as secondary pollution, become the main method of recent improvement formaldehyde.
NACF is through charing, activation and the novel charcoal material that makes by organic fiber.Because the NACF specific area is more flourishing, micro-pore diameter is little and abundant, and micropore directly is opened on fiber surface simultaneously, thus have that adsorption capacity is big, adsorption efficiency is high, advantage such as absorption, desorption rate are fast.
Expanded graphite has high porosity, characteristics such as high surface area, and the absorption of expanded graphite PARA FORMALDEHYDE PRILLS(91,95), best adsorption time is 1h, the gas optimum flow rate is 500mL/min.Expanded graphite is compared with adsorbents such as active carbon, charcoals, and the adsorption effect of its PARA FORMALDEHYDE PRILLS(91,95) is best.
Bamboo wood has special microcellular structure, becomes bamboo charcoal through pyrolysis charring, and porous bamboo charcoal has stronger absorption property, available Purge gas etc.Studies show that the optimal adsorption condition of 250 order bamboo charcoal powder PARA FORMALDEHYDE PRILLS(91,95)s is; 55 ℃ of temperature, time 3h.The adsorbance maximum of bamboo charcoal PARA FORMALDEHYDE PRILLS(91,95) reaches 68.5mg/g under this condition.The absorption of bamboo charcoal PARA FORMALDEHYDE PRILLS(91,95) is mainly physical absorption, therefore is easier to desorption, because the bamboo charcoal source is abundant, cost is lower, has broad prospects as new environmental protection adsorption functional material.
Sorbing material modenite load catalysis material TiO
2Trace formaldehyde in the degradable air, with transparent silochrom as photochemical catalyst TiO
2Carrier, the clearance of photocatalytic degradation formaldehyde is 84.12% in the 27h.
Nanoscale TiO
2It is stable to have chemical property, indissoluble, characteristics such as harmless, and composite Nano TiO
2/ ZrO
2Can also reuse, be a kind of effective environment-friendly materials of absorbing formaldehyde.When concentration of formaldehyde surpasses 0.08mg/m
3The time, effective adsorption rate of nano composite material PARA FORMALDEHYDE PRILLS(91,95) will be greater than more than 95%.
At present, the formaldehyde adsorption production of market sale mainly is " a passive absorbent-type ".Passive absorbent-type product is placed on certain, room, only to around very among a small circle pernicious gas suction-operated is arranged, and to spreading in the formaldehyde in each space, room, then powerless.
Summary of the invention
The present invention is exactly in order to solve the formaldehyde pollution problem, and a kind of " initiatively absorbent-type " formaldehyde gas absorber is provided.
The present invention realizes by following technical scheme.
A kind of formaldehyde gas absorber, set up separately in the container of air inlet barrier, exhaust barrier its leg front, back, behind the air inlet barrier, be provided with motor-driven ventilating fan, and by being provided with the physical absorption layer of forming by active carbon and catalysis material behind the forward direction successively, by Sodium Polyacrylate is adsorbing agent carrier, adds the formaldehyde adsorption reaction layer that crosslinking agent and formaldehyde adsorbent form.
She Ji the present invention like this, the exhaust fan of employing front initiatively sucks formaldehyde and the pernicious gas in the environment, passes through physical absorption layer and adsorption reaction layer successively, PARA FORMALDEHYDE PRILLS(91,95) and pernicious gas adsorb, react, and the discharge of the gas after will removing the evil, therefore, become " initiatively absorbent-type " product.
