The first valve 130 on the smoke inlet pipe 110 and the first exhaust pipe 120 is opened, the pretreated (dried) rubber smoke enters the activated carbon adsorption tank 100 through the smoke inlet pipe 110, after the rubber smoke enters the activated carbon adsorption tank 100, organic substances in the rubber smoke are adsorbed by activated carbon and then attached to the surface of the activated carbon, so that the rubber smoke is purified, and the purified rubber smoke is then exhausted in high altitude through the first exhaust pipe 120 via a fan and a chimney. The activated carbon adsorption box 100 is filled with honeycomb activated carbon or fibrous activated carbon, so that the adsorbent has long service life, low resistance of an adsorption system and high purification efficiency on rubber smoke.
The desorption regeneration device 200 comprises a heating chamber 210, a combustion chamber 220 and a first heat exchanger 230 which are connected in sequence, wherein a tube side inlet of the first heat exchanger 230 is connected with the combustion chamber 220, the tube side inlet is further connected with a first air inlet pipeline 231, a second valve 232 is arranged on the first air inlet pipeline 231, a desorption hot gas inlet pipeline 233 is connected between a tube side outlet of the first heat exchanger 230 and the activated carbon adsorption tank 100, a desorption hot gas outlet pipeline 234 is connected between the activated carbon adsorption tank 100 and the heating chamber 210, a third valve 235 is arranged on each of the desorption hot gas inlet pipeline 233 and the desorption hot gas outlet pipeline 234, a honeycomb-shaped noble metal catalyst is filled in the combustion chamber 220, the combustion chamber 220 is connected with a second discharge pipeline 221, a fourth valve 222 and a first heat exchange pipeline 223 are arranged on the second discharge pipeline 221, the first heat exchange pipeline 223 is positioned between the fourth valve 222 and the combustion chamber 220, the first heat exchange pipeline 223 is connected with a shell side inlet of the first heat exchanger 230, and is provided with a fifth valve 224.
When the activated carbon in the activated carbon adsorption box 100 is saturated by adsorption, the first valve 130 on the smoke inlet pipeline 110 and the first exhaust pipeline 120 is closed, the desorption regeneration device 200 is started to desorb the activated carbon in the activated carbon adsorption box 100, the second valve 232, the third valve 235, the fourth valve 222 and the fifth valve 224 are firstly opened, air enters the first heat exchanger 230 through the first air inlet pipeline 231, because the air enters the first heat exchanger 230 through the first air inlet pipeline 231 directly, the temperature is low, the activated carbon cannot be desorbed, the air entering the first heat exchanger 230 enters the heating chamber 210 through the desorption hot air inlet pipeline 233, the activated carbon adsorption box 100 and the desorption hot air outlet pipeline 234 in sequence, the air is heated in the heating chamber 210, the heated air then enters the activated carbon adsorption box 100 through the desorption hot air inlet pipeline 233, and the air is heated to the desorption temperature, the desorption gas enters the heating chamber 210 through the desorption hot gas outlet pipeline 234, the desorption gas is desorbed by the activated carbon adsorption box 100, the temperature is reduced to some extent, the heating chamber 210 is required to be heated to the initial temperature of the catalytic oxidation reaction (the initial temperature is lower than the desorption temperature), specifically, the initial temperature of the desorption gas is about 320 ℃, the temperature is reduced to about 180 ℃ after the desorption gas is desorbed by the activated carbon adsorption box 100, but the initial temperature of the catalytic oxidation combustion of the desorption gas in the combustion chamber 220 is about 300 ℃, therefore, the temperature of the desorption gas in the heating chamber 210 is required to be increased to about 300 ℃, then the combustion chamber 220 is filled with the honeycomb-shaped noble metal catalyst, the honeycomb-shaped noble metal catalyst reduces the activation energy of the organic matters in the desorption gas, and the organic matters are subjected to flameless combustion at a lower temperature (generally from 250 ℃ to 300 ℃), the principle is that when the desorbed gas passes through the honeycomb-shaped noble metal catalyst, the desorbed gas is firstly adsorbed to the surface of the honeycomb-shaped noble metal catalyst and then is subjected to catalytic combustion at a certain temperature, so that the purpose of purification is achieved. Organic matters are combusted under the action of the honeycomb-shaped noble metal catalyst and are decomposed into carbon dioxide and water, a large amount of heat is released at the same time, organic waste gas originally adsorbed in the activated carbon is desorbed, gaseous organic pollutants are converted into carbon dioxide and water vapor through catalytic combustion, and the treated air flow is discharged up to the standard at high altitude.
A part of the high-temperature gas after combustion passes through the tube-pass inlet of the first heat exchanger 230 and then is mixed with the air entering through the first air inlet pipe 231, and then the activated carbon in the activated carbon adsorption tank 100 is cyclically desorbed through the desorption hot gas inlet pipe 233. A part of the burned high-temperature gas is discharged through the second discharge pipe 221, and a part of the burned high-temperature gas enters the shell side of the first heat exchanger 230 through the first heat exchange pipe 223, and exchanges heat with the air entering through the first air inlet pipe 231, so that the temperature of the air entering the activated carbon adsorption box 100 reaches the desorption temperature requirement, and a part of heat is recovered.
The heating chamber 210 heats the desorbed gas to about 300 ℃, so that the desorbed gas is heated to the initial temperature of the catalytic oxidation reaction, and the released heat is recycled at the back end, so that the temperature of the circulating desorbed gas is kept at about 300 ℃, the heating chamber 210 can be closed after the heat balance is achieved (generally, the heat balance heating chamber 210 needs to be started for about 1 hour), the combustion chamber 220 can maintain spontaneous combustion without external heating, and the whole waste gas treatment process almost only consumes the power of a fan, so that energy is saved, part of the hot tail gas generated by combustion is discharged into the atmosphere, and most of the hot tail gas is recycled and sent to the activated carbon adsorption tank 100 for supplying the heat for activated carbon desorption regeneration. Thus, the heat energy required by combustion and desorption can be met, and the purpose of energy conservation is achieved. The regenerated active carbon can be adsorbed next time, and the aim of recycling can be achieved.
Specifically, can be after activated carbon adsorption case 100 adsorbs the fixed time to rubber flue gas, start desorption regenerating unit 200, through desorption regenerating unit 200 to the activated carbon regeneration in the activated carbon adsorption case 100 time of predetermineeing, then adsorb the rubber flue gas again, also regularly carry out the desorption to activated carbon adsorption case 100, realize recycling promptly.
It can be seen that, in the reusable rubber flue gas treatment system disclosed in the present application, when the activated carbon in the activated carbon adsorption tank 100 reaches adsorption saturation, the activated carbon can be desorbed through the desorption regeneration device 200, organic waste gas originally adsorbed in the activated carbon is desorbed, gaseous organic pollutants are converted into carbon dioxide and water vapor through catalytic combustion, no secondary pollution is generated, a part of hot tail gas generated by combustion is discharged into the atmosphere, most of the hot tail gas is recycled and sent to the activated carbon adsorption tank 100 for heat supply of activated carbon desorption regeneration, so as to recycle the released heat, so as to achieve thermal balance, the combustion chamber 220 can maintain spontaneous combustion, no external heating is used, so as to achieve the purpose of energy saving, so that the treatment cost of rubber flue gas is low, the activated carbon after desorption regeneration can continue to adsorb the rubber flue gas, so as to achieve the purpose of recycling, a worker does not need to frequently change the activated carbon in the activated carbon adsorption tank 100, the activated carbon can be recycled, so as to avoid that the use amount of the activated carbon is large and the treatment cost of the rubber flue gas is high, and the workload of the worker is reduced, and the labor intensity is reduced, and the activated carbon can be regularly changed, so that the activated carbon can be regularly regenerated to ensure that the saturated adsorption and the environment can be replaced, and the saturated adsorption can not be directly adsorbed and the saturated adsorption can be adsorbed and the pollution of the environment can be prevented.
For improving the desorption efficiency to the activated carbon, in an optional embodiment, in activated carbon adsorption box 100, the flow direction of rubber flue gas is opposite to the flow direction of desorption hot gas, that is to say, when activated carbon adsorption box 100 adsorbs the rubber flue gas, the direction that the rubber flue gas passes through activated carbon adsorption box 100 is first direction, when carrying out desorption regeneration to the activated carbon, the flow direction of desorption hot gas is the second direction, first direction and second opposite direction, this kind of mode of arrangement, can shorten desorption time about 20%, thereby improve the desorption efficiency of activated carbon.
In this application, desorption gas is through the desorption back of active carbon adsorption box 100, the temperature descends to some extent, need heating chamber 210 to heat to catalytic oxidation reaction's initial temperature (initial temperature is less than desorption temperature), then just can get into the burning in the combustion chamber 220, only when the temperature after desorption gas through active carbon adsorption box 100 desorption reaches catalytic oxidation reaction's initial temperature, just need not heating chamber 210 heating, it can realize to need heating cycle many times, this will prolong the time that reaches thermal balance, lead to heating chamber 210 to need open the long time, energy-conserving effect is obvious inadequately. Based on this, in an alternative embodiment, the desorption regeneration device 200 may further include a second heat exchanger 240, the desorption hot gas outlet pipe 234 is connected to a tube-side inlet of the second heat exchanger 240, a tube-side outlet of the second heat exchanger 240 is connected to the heating chamber 210, a second heat exchange pipe 225 is further disposed on the second discharge pipe 221 and located between the fourth valve 222 and the combustion chamber 220, and the second heat exchange pipe 225 is connected to a shell-side inlet of the second heat exchanger 240 and is provided with a sixth valve 226.

Based on this, in an alternative embodiment, in the flow direction of the desorption hot gas in the desorption hot gas inlet pipeline 233, a first electrokinetic flow valve 236, a temperature measuring sensor 237 and a second electrokinetic flow valve 238 are disposed on the desorption hot gas inlet pipeline 233 and are located between the first heat exchanger 230 and the third valve 235, a second electrokinetic flow valve 239 is disposed on the second electrokinetic flow valve 238, and the first electrokinetic flow valve 236 and the second electrokinetic flow valve 239 are electrically connected to the temperature measuring sensor 237.
