Description

Combined type laboratory exhaust gas purifying processing device
Technical field
The utility model belongs to a kind of combined type laboratory exhaust gas purifying processing device of widespread demand in the field of environment protection.
Background technology
In most of physics and chemistry and biology laboratory, produce various different toxic harmful exhaust gas of different nature, acid-base class for example, stench class, various chemical class, microbiology class waste gas etc. through regular meeting.The waste gas that the present existing state of the art is single character is relatively more effective on handling, surpassing two or more waste gas of different nature can't handle simultaneously, and most for the treatment of apparatus are bulky because of it, noise can't be placed in the common lab greatly, and can not carry out different disposal intensity according to different exhaust gas concentrations and regulate.Cause at present that these laboratory exhaust gas can not get effective purified treatment, can only be simply carry out adsorption treatment once or not and directly be discharged among the atmosphere, cause air pollution in various degree with charcoal absorption.Make and capture this technology and become a difficult problem.Along with improving constantly of environmental protection requirement, more urgent to this technology requirement.
Summary of the invention
In order to solve the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of combined type laboratory exhaust gas purifying processing device, can realize laboratory combined type waste gas adsorption cleaning processing.It has dust-filtering simultaneously, chemisorbed, wet cleaning, but the adsorption cleaning that multiple function such as regulated at will can efficient energy-saving carries out multiple laboratory waste gas handle, solved the not tractable difficult problem of exhaust emission in the laboratory.
To achieve these goals, the technical solution adopted in the utility model provides a kind of combined type laboratory exhaust gas purifying processing device, wherein: this device includes and comprises the air valve that can control the air inlet intake, the nuclepore membrane filter of a band dehumidification function is used for various microorganisms and dust-like the gas dry and generation of filtration experiment chamber, connect one with the second level adsorption treatment device of solid absorbent (as activated carbon etc.) and be connected to three grades of combined type adsorption cleaning treating apparatus that the tower adsorption treatment device of liquid spraying is formed thereafter thereafter, the different toxic and harmfuls multiple of different nature of its treatment of laboratory generation simultaneously, adjustable speed frequency modulation explosion-proof fan for silencing means is used for producing the absorption wind regime, and above-mentioned air valve open amount controlled simultaneously by manual control handle and frequency modulation explosion-proof fan rotating speed reaches the effect that has realized guaranteeing that promptly purification efficiency is energy-saving and cost-reducing again according to exhaust gas concentration adjustments of gas flow and flow velocity.The above-mentioned innocuous gas that has between at different levels induced duct to connect after air outlet will be handled respectively is discharged among the atmosphere.Effect of the present utility model is: this device has one-level and filters the requirement that the such three grades of compound specific manner that adds back two-stage adsorption treatment can reach the multiple different toxic harmful exhaust gas of different nature of treatment of laboratory generation simultaneously.Manual control handle is controlled above-mentioned air valve open amount and frequency modulation explosion-proof fan rotating speed simultaneously and is reached according to exhaust gas concentration adjustments of gas flow and flow velocity and realized the effect that guarantees that promptly purification efficiency is energy-saving and cost-reducing again.This device is little because of its volume, and the noise I is placed within the common lab room, can reach harmless emission after combined type is handled, and helps protecting environment thereby reach.Solved the complicated and effective adsorption treatment technical barrier in this respect of exhaust gas constituents that laboratory for a long time produces.

The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated combined type laboratory exhaust gas purifying processing device of the present utility model.
The utility model is a kind of combined type laboratory exhaust gas purifying processing device, this device includes: the one-level waste gas filtering adds that such three grades of compound special construction of back two-stage waste gas adsorption treatment are for the waste gas various of different nature that produces in the laboratory, divided for three steps carried out purified treatment until reaching safety dumping, at first these waste gas are sucked the air valve 3 that can control the air inlet air quantity, this air valve can make air valve open big by the adjusting that manual control handle 1 people is or turn down the concentration of handling different waste gas and the flow of waste gas.First order processor: the nuclepore membrane filter 4 of a band dehumidification function is used for various microorganisms and dust-like the gas dry and generation of filtration experiment chamber, this miillpore filter can effectively filter out the large particulate matters such as dust in the waste gas, but can't adsorb for stench class and chemical classes waste gas.This class waste gas need enter of the being connected second level adsorption treatment device 5 with solid absorbent (as activated carbon etc.) absorption.The second level adsorption treatment device 5 of this device can be selected corresponding solid adsorption material according to the character of different waste gas.The stench class and the part chemical classes waste gas of general absorbent charcoal material adsorbable 90%.Last remaining waste gas enters the third level processor that is connected: the tower adsorption treatment device 6 of liquid spraying.The tower adsorption treatment device 6 of this liquid spraying can select optimal adsorptive liquid to spray absorption according to the character of residual gas.The adsorption efficiency of the tower adsorption treatment device 6 of this device liquid spraying can reach 95%.The toxic and harmful multiple of different nature of this combined type laboratory exhaust gas purifying processing device treatment of laboratory generation simultaneously that the above-mentioned three grades of processors of different nature of process are formed.Because the various waste gas that laboratory produces are a lot of less with respect to the industrial waste gas amount that industrial and mining enterprises produce, so narrowing down to that the volume of this combined type laboratory exhaust gas purifying processing device can be suitable is convenient to be installed in the laboratory.And the blower fan of this covering device and water pump system all add noise reduction and soundproof measures makes it to reach quiet effect.Adjustable speed frequency modulation explosion-proof fan 7 for silencing function is used for producing the absorption wind regime, and above-mentioned air valve 3 open amounts controlled simultaneously by manual control handle 1 and adjustable speed frequency modulation explosion-proof fan 7 rotating speeds reach the effect that has realized guaranteeing that promptly purification efficiency is energy-saving and cost-reducing again according to exhaust gas concentration adjustments of gas flow and flow velocity.Two state the innocuous gas that has induced duct 2 to connect after the exit will be handled between this device each several part respectively is discharged among the atmosphere.Reach innoxious discharging.
