A kind of plasma adds charcoal treatment silk-screen organic exhaust gas device
Technical field
The utility model belongs to organic waste gas treatment equipment field, relates in particular to a kind of plasma and adds charcoal treatment silk-screen organic exhaust gas device.
Background technology
In prior art, traditional VOCs treatment adopts Production by Catalytic Combustion Process conventionally, catalytic combustion is that organic exhaust gas is heated to and opens combustion temperature, under the effect of catalyst, carry out non-flaming combustion, generate carbon dioxide and water and discharge amount of heat, the key of catalyst combustion reaction is to select suitable catalyst.Be active high to the requirement of catalyst, special requirement low temperature active is good, to start reaction at alap temperature.Combustion reaction is exothermic reaction, discharge the surface that a large amount of heat can make catalyst and reach the high temperature of 500~1000 DEG C, and catalyst is easily because melting reduces activity, so require the catalyst can be high temperature resistant.The subject matter that Production by Catalytic Combustion Process exists is that catalyst is easily poisoning smaller with process range, generally processes the organic exhaust gas of high concentration, is not suitable for the processing of the waste gas of the low concentration of serigraphy generation.
Summary of the invention
The purpose of this utility model is to provide a kind of plasma to add charcoal treatment silk-screen organic exhaust gas device, thereby solves the problem in above-mentioned background technology.
The utility model content is achieved through the following technical solutions:
A kind of plasma adds charcoal treatment silk-screen organic exhaust gas device, comprise plasma purifier, activated carbon adsorber, blower fan, described activated carbon adsorber is provided with air inlet and air outlet, described plasma purifier is connected with the air inlet of activated carbon adsorber, and the air outlet of described activated carbon adsorber is connected with blower fan.
Described activated carbon adsorber outside one side and top are provided with safety barrier.
Described charcoal absorption top of tower is provided with some discharge ports.
The utility model adopts plasma purifier and activated carbon adsorber to combine to process silk-screen organic exhaust gas.
The principle that plasma purifies is under the effect of extra electric field, what medium discharge produced takes in a large number and can bombard contaminant molecule by electronics, make its ionization, dissociate and excite, then physics, the chemical reaction of series of complex have just been caused, make complicated macromolecule contaminant change simple little molecule safe material into, or make poisonous and harmful substance be transformed into material nontoxic or the low evil of low toxicity, thereby make the pollutant removal of being degraded.Because of its ionization after produce electronics average energy at 10ev, suitably control reaction condition can realize be generally difficult to realize or the very slow chemical reaction of speed become very quick.
Active carbon is a kind of very tiny carbon granule, has very large surface area, and also has more tiny hole---capillary in carbon granule.This capillary has very strong adsorption capacity, because the surface area of carbon granule is very large, so can fully contact with gas (impurity).Encounter capillary when these gases (impurity) and be adsorbed, aseptic.The surface area of active carbon is larger, and adsorption capacity is just stronger, and active carbon is nonpolar molecule, is easy to adsorb adsorbate nonpolar or that polarity is very low; The size of acticarbon particle, structure and distribution situation and the surface chemical property etc. of pore also has a great impact absorption.The character of adsorbate depends on concentration of the size of its solubility, surface free energy, polarity, adsorption molecule and degree of unsaturation, attached matter etc.While coexisting multiple adsorbate, adsorption capacity when active carbon only contains this kind of adsorbate to the adsorption capacity ratio of certain adsorbate is poor.
The utlity model has following beneficial effect:
The utility model is simple in structure, adopts plasma purifier and activated carbon adsorber to combine the organic exhaust gas of the low concentration of processing silk-screen generation, can purify multiple pollutant simultaneously, and treatment effect is better, applied widely, and equipment investment is few, convenient management.

Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of plasma adds charcoal treatment silk-screen organic exhaust gas device, comprise plasma purifier (1), activated carbon adsorber (2), blower fan (3), described activated carbon adsorber (2) is provided with air inlet (5) and air outlet (6), described plasma purifier (1) is connected with the air inlet (5) of activated carbon adsorber (2), and the air outlet (6) of described activated carbon adsorber (2) is connected with blower fan (3).
Described activated carbon adsorber (2) outside one side and top are provided with safety barrier (4).
Described charcoal absorption top of tower is provided with some discharge ports (7).
When concrete enforcement, after silk-screen workshop waste gas enters and purifies in plasma purifier, then after entering active absorption tower and adopting the method for activated adoption to adsorb, then give off clean air through blower fan.The utility model is simple in structure, adopts plasma purifier and activated carbon adsorber to combine the organic exhaust gas of the high-concentration and low-concentration of processing silk-screen generation, can purify multiple pollutant simultaneously, and applied widely, equipment investment is few, convenient management.
