A kind of toxic and harmful gas purging device
Technical field
The utility model relates to a kind of toxic and harmful gas purging device, belongs to the device that purifies air.
Background technology
Along with a large amount of uses of modern architecture material, the volatility toxic and harmful that construction materials such as binding agent, coating and paint discharge in the construction and decoration process, having become as organic compound (VOCs) influences the main root of indoor air quality.VOCs gas has neurotoxicity, renal toxicity, hepatotoxicity wind agitation and carcinogenicity etc., and the mankind healthy had great threat.Construction material is polluted in ventilation, zero and air purifier is to solve indoor toxic and harmful to pollute three kinds of main paties, ventilation can be subjected to the influence of outdoor air quality, zero pollution construction material is basic solution route but is not easy to realize, so air purifier becomes the first-selection of removing indoor toxic and harmful.But existing in the market air purifier all exists certain self-defect, in fact can only reach the effect of " pure and fresh " air as traditional negative ion air-cleaner, and most of pollutant can't be eliminated, and leaks ozone easily; The photocatalysis air purifying device catalyst be in for a long time under the high density pollution environment actively can reduce, the catalyst micropore is vulnerable to dust and stops up; The uviol lamp air purifier need regularly replace with problems such as assurance light intensity; Absorption type air purifier is obvious to handling the toxic and harmful effect, yet the usually saturated restriction of sorbent suspension absorption needs the periodic replacement adsorbent, can not continue to purify air.
Summary of the invention
The purpose of this utility model provides a kind of toxic and harmful gas purging device with absorption and desorption function.
Toxic and harmful gas purging device of the present utility model, comprise casing, casing by about two dividing plates be separated into three unit that are arranged in order, in first module, be equipped with and handle with blower fan and air heater, be equipped with adsorption runner in Unit second, be equipped with the regeneration blower fan in Unit the 3rd, and offer air inlet, have circular hole on two dividing plates, be provided with framework in the circular hole, a left side, the corresponding sector region that is separated to form by framework on the right clapboard links to each other with an end of first closed conduit and second closed conduit respectively, the other end of first closed conduit links to each other with air heater, the other end of second closed conduit links to each other with blower fan with regeneration, be filled with honeycomb substrates between the rotating shaft of adsorption runner and the shell, attachment molecules sieve adsorbant on the base material, the center of two Partition board frames about its rotating shaft is supported on, shell has the chain that is meshed with the driven wheel of driven by motor.
Above-mentioned adsorbent of molecular sieve can be the adsorbent of molecular sieve of commercially available calcium X type or the adsorbent of molecular sieve of calcium A type, can select different adsorbents according to the kind of handling pernicious gas.
Toxic and harmful gas purging device of the present utility model can be in the absorption toxic and harmful desorption toxic and harmful, making that whole air cleaning process is continual carries out, and need not frequently to change adsorbent.

Specific embodiments
Further specify the utility model below in conjunction with accompanying drawing.
Referring to accompanying drawing, toxic and harmful gas purging device comprises casing 1, casing by about two dividing plates 2,3 be separated into three unit that are arranged in order, in first module, be equipped with and handle with blower fan 4 and air heater 5, be equipped with adsorption runner 6 in Unit second, be equipped with regeneration blower fan 7 in Unit the 3rd, and offer air inlet 13, have circular hole on two dividing plates, be provided with framework 8 in the circular hole, usually make the diameter of circular hole identical,, improve the treatment effect of toxic and harmful so that increase absorption and desorption face with the adsorption runner diameter.In the legend, framework is a cross frame, cross frame is divided into four sector regions with circular hole, the 90 ° of sector regions in left clapboard circular hole upper end link to each other with an end of first closed conduit 9, the other end of first closed conduit 9 links to each other with air heater, right clapboard circular hole upper end links to each other with an end of second closed conduit 10 with the corresponding 90 ° of sector regions of left clapboard, and the other end of second closed conduit 10 links to each other with blower fan with regeneration.Be filled with honeycomb substrates 11 between the rotating shaft of adsorption runner 6 (see figure 2)s and the shell, base material can adopt porous ceramics, attachment molecules sieve adsorbant on the base material, the center of two dividing plate cross frames about the rotating shaft of adsorption runner is supported on, shell have the chain 12 that is meshed with the driven wheel of driven by motor.
This device operation principle is as follows:
Adsorption runner slowly rotates, handling with under the effect of blower fan, pending contaminated air enters the 270 ° of sector regions in circular hole lower end from air inlet, and airborne toxic and harmful is adsorbed the adsorbent absorption that runner adheres to, and clean air then is sent to outside the casing.The adsorption runner of the 270 ° of sector regions in circular hole lower end has absorbed toxic and harmful, become saturation state, forward the 90 ° of sector regions in circular hole upper end to and enter regenerative process, under the effect of regeneration blower fan, enter the 90 ° of sector regions in circular hole upper end through the air heater heated hot air heated by first closed conduit, the toxic and harmful of the adsorption runner absorption of the 90 ° of sector regions in circular hole upper end evaporate in the hot-air by desorption, hot-air has become and has contained poisonous harmful gas pollution air, and contaminated air then is sent to the outer contaminated air treating apparatus of casing by second closed conduit.General 8~10 weeks of the rotating speed of runner/time, air constantly purifies, and goes round and begins again and carries out adsorption process continuously, need not frequently to change adsorbent.
