Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: pretreatment unit 1, adsorption reaction room 2, blower fan 3, separator 4, desorption and regeneration case 5, catalytic combustor 6, vavuum pump 7.
Detailed description of the invention
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises pretreatment unit 1, adsorption reaction room 2, separator 4, desorption and regeneration case 5, catalytic combustor 6, the top of described pretreatment unit 1 is connected to the bottom of adsorption reaction room 2, adsorption column is provided with in adsorption reaction room 2, adsorption column inside is provided with reaction tube, reaction tube inside division is three independent stratums, can add different sorbing material as adsorbent.When each layer inserts sorbing material of the same race, contrast the treatment effect of different sorbing material by parallel test.When inserting different sorbing material, different sorbing material associated treatment organic exhaust gas effect can be investigated; The top of described adsorption reaction room 2 is connected to the left side of catalytic combustor 6, and the right side of catalytic combustor 6 is connected to the side inlet of pretreatment unit 1; The bottom of separator 4 is connected to desorption and regeneration case 5, and top is connected to catalytic combustor 6.
Wherein, be provided with the adsorption tube of filling discolour silica gel ball in pretreatment unit 1, first pretreatment carried out to organic exhaust gas, while realizing organic exhaust gas drying and dehydrating, Impurity removal in gas can be realized; The sorbent material layer of catalyst filling modification in above-mentioned catalytic combustor 6, thus reach catalytic treatment, adsorption reaction and carry out simultaneously, realize organic exhaust gas and efficiently process.Example: if select NACF as organic waste-gas adsorbant, then the modification of catalyst soakage method is carried out to activated carbon fiber material, thus the adsorbent obtaining that load has catalyst; The side of above-mentioned separator 4 is provided with blower fan 3, and the bottom of desorption and regeneration case 5 connects vavuum pump 7.
The course of work of the present utility model is:
First industrial organic exhaust gas enters pretreatment unit from bottom, carries out drying, impurity elimination process.After enter by bottom the adsorption reaction post that many adsorption tubes connect.After adsorption treatment, organic exhaust gas sends into catalytic combustion indoor.Meanwhile, blower fan blasts air and enters separator, and separator carries out the process of imurity-removal, dust to air, and after purification, air is as combustion adjuvant, converges, jointly sends into catalytic combustor, for catalytic combustion provides oxygen with organic exhaust gas after adsorption treatment.Organic exhaust gas after purified treatment, if do not reach discharge standard process capable of circulation; If reach discharge standard, directly air can be entered.
After the utility model runs a period of time, adsorbent in indoor for adsorption reaction adsorption tube when will reach capacity, takes out, sends into separator, and in adsorption tube, insert fresh sorbing material or regenerative adsorption material by upon adsorption dose.Now, blower fan is sent into air and is purged saturated adsorption agent, and adsorbent carries out downward spiral rotating motion with air in outside, and carries out desorption in the process.After desorption, sorbing material is thrown on wall under the action of the centrifugal, and falls into bottom dust hopper.Collect the rear adsorbent of process in dust hopper, feeding removes regeneration case and carries out vacuum high-temperature desorption and regeneration, and regeneration processed sorbing material can send into the indoor direct use of adsorption reaction.The organic gas removed then carries out oppositely upwards screw with fresh air in inside, and converges from the rear gas circuit of upper outlet and absorption, enters catalytic combustor and carries out after-treatment.Similarly, organic exhaust gas after purified treatment, if do not reach discharge standard process capable of circulation; If reach discharge standard, directly air can be entered.
