Description

A kind of use for laboratory catalytic converter
Technical field
The invention belongs to gas purifying equipment field, and in particular to a kind of use for laboratory catalytic converter.
Background technology
Prior art is to waste gas purification treatment mainly for indoor exhaust air treatment and industrial waste gas treatment, indoor exhaust air treatment Refer to the purification of general waste gas, and in the waste gas that especially discharges during high school chemical experiment for the treatment of of experiment indoor exhaust air, It is characterized in the mixed gas of simple common chemicals waste gas and general indoor exhaust air such as formaldehyde, the spy with gas component Point.
To general indoor purifying processing method and equipment, how on the books prior art is and open, such as Application No. Technology disclosed in CN201210477083.4, the patent document of entitled " indoor air cleaning system ", is to indoor supplement By the fresh air that filter is filtered, filter employs electrostatic adsorption device, active carbon slab, silver ion screen pack and light and urges Change filtering module, it is clear that the system is only through air of traditional absorption with filtering to getting in and purifies, and structure is multiple Miscellaneous, module is more, and enforcement difficulty is big.Such as Application No. again
The patent document institute of CN201210392929.4, entitled " purifier and method of a kind of indoor air through electrostatic atomization " Disclosed method is the method being combined with electrostatic atomization water washing cleaning using electrostatic precipitation purification, and air first passes around screen pack The forceful electric power place formed with high-voltage corona, pernicious gas is decomposed by electric field, then the charged water spray by being formed by electrostatic atomization Area, further dissolves pernicious gas, adsorbs grit, then obtains deep purifying through photocatalyst filtering net, and it is gentle to occur with reference to anion Stream guiding, reaches the purpose of indoor air circulation high-efficient purification;But the charged droplets carrying capacity that electrostatic capillary is produced is difficult to Effectively control, the charged formation mist droplet particle size uniformity is poor, and the problems such as the minute nozzle for using easily produces blocking, and need Carry out the supplement of liquid.
By foregoing description, inventor find indoor gas are carried out in the prior art purified treatment have it is baroque Common defects, typical problem is to employ electrolysis mode or, this mode is obvious using having actually in laboratory Problem, be exactly dangerous higher, because often producing hydrogen and oxygen in chemical experiment, by screen pack and high-tension electricity The dizzy forceful electric power place for being formed, pernicious gas decomposes power network by electric field, and commonly known to be that hydrogen and oxygen may then occur quick-fried It is fried.In many rural high laboratories, without condition in the case of, then be difficult to use safety prevention measure, therefore be directed to Laboratory air or waste gas are purified, and all there is equipment complexity, and cost is high, without the problem for considering security conscientiously.
And catalysis process is used, such as Application No. CN200810051706.5, a kind of entitled " indoor air purification side Device disclosed in the patent document of method and device " includes casing, control system, induced draught system, adsorption system and catalysis burning System, breaches the pattern that traditional replacing adsorbent purifies the air of a room, by adsorption system and the organic knot of catalytic combustion system It is combined, harmful substance is converted into harmless CO2And H2O, forms effective air cleaning system.Catalyst is loaded for Pt In Al2O3Or TiO2And Al2O3Complex carrier on, auxiliary agent is MnO2Deng metal oxide;Because sorbing material is recycled, no Need to change adsorbent, running cost is low.Although the above method employs catalysis process, catalyst cost first is relatively high, and And the clean-up effect of waste gas is undesirable.
Thus, purified treatment is carried out for laboratory exhaust gas, in summary the problem of background technology was, it is necessary to propose one kind both Removing exhaust gas can be effectively removed, and safe and reliable, the cleaning equipment of low cost.
