The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 and 2, an embodiment of the application discloses an exhaust gas treatment system for treating a regeneration exhaust gas generated in a triethylene glycol regeneration process.
The disclosed offgas processing system includes a reboiler 100, a gas-liquid separator 200, and an incinerator 300, wherein the reboiler 100, the gas-liquid separator 200, and the incinerator 300 are sequentially connected such that a regeneration offgas flows along the reboiler 100, the gas-liquid separator 200, and the incinerator 300 sequentially. So, can heat regeneration waste gas through reboiler 100 to make regeneration waste gas reach preset the temperature, then regeneration waste gas carries out gas-liquid separation in getting into vapour and liquid separator 200, thereby can get rid of the free water in the regeneration waste gas, in order to obtain more pure regeneration waste gas, regeneration waste gas after the dehydration gets into to burn in burning furnace 300.
Considering that the regeneration waste gas generates heat during incineration and the reboiler 100 needs to consume heat during heating of the regeneration waste gas, in the embodiment of the present application, the heat generated by incinerating the regeneration waste gas may be transmitted to the reboiler 100 to provide heat for the reboiler 100, so that heat recovery and reuse may be achieved.
The exhaust gas treatment system further includes a connection pipe 610, the connection pipe 610 is connected between the incinerator 300 and the reboiler 100, and incineration flue gas generated by incinerating the regeneration exhaust gas in the incinerator 300 may be introduced into the reboiler 100 through the connection pipe 610, thereby providing heat to the reboiler 100.
In the embodiment of the application, the exhaust gas treatment system can be used for treating the triethylene glycol regeneration tower 400 which discharges substances containing BTEX and H2The regeneration waste gas of S is treated, specifically, the regeneration waste gas is introduced into the reboiler 100, the regeneration waste gas is heated through the reboiler 100, then the heated regeneration waste gas is introduced into the gas-liquid separator 200 for gas-liquid separation to remove free water in the regeneration waste gas, then the regeneration waste gas is introduced into the incinerator 300 for incineration, incineration flue gas generated in the incineration process is introduced into the reboiler 100 through the connecting pipeline 610, and therefore heat can be provided for the reboiler 100 through the incineration flue gas.
Based on the above setting, can prevent effectively that the regeneration waste gas that produces among the triethylene glycol regeneration process from directly discharging into the atmosphere and causing harm to health, surrounding environment, meanwhile, can also be to regeneration waste gas reuse, as reboiler 100's heating source to can realize the energy and recycle, and reduce reboiler 100 and heat the required energy, and then can reach the purpose of energy saving.
To enable connection of the reboiler 100 to other components, in some embodiments, the reboiler 100 is provided with a first inlet, a first outlet, a second inlet, and a second outlet. The first inlet is used for being connected with the discharge end of the triethylene glycol regeneration tower 400, so that the regeneration waste gas generated in the triethylene glycol regeneration process flows into the first inlet through the discharge end of the triethylene glycol regeneration tower 400 and enters the interior of the reboiler 100, and therefore the entering regeneration waste gas can be heated by the reboiler 100, the temperature of the regeneration waste gas is increased, and the incineration efficiency of the regeneration waste gas is improved.
The first outlet is connected with the inlet of the gas-liquid separator 200, so that the regeneration waste gas heated by the reboiler 100 can flow into the gas-liquid separator 200 through the first outlet, so that the regeneration waste gas is subjected to gas-liquid separation in the gas-liquid separator 200, and free water in the regeneration waste gas is removed, so that the purer regeneration waste gas is obtained, and the incineration is facilitated.
The second inlet is connected to the connection pipe 610, that is, one end of the connection pipe 610 is connected to the second inlet, and the other end of the connection pipe 610 is connected to the outlet of the incinerator 300, so that incineration flue gas generated by incinerating the regeneration waste gas in the incinerator 300 can be sequentially delivered into the reboiler 100 through the connection pipe 610 and the second inlet, thereby providing heat to the reboiler 100, and thus enabling the reboiler 100 to heat the regeneration waste gas therein.
The second outlet is used to connect to a stack 500, through which stack 500 the off-gas in reboiler 100 may be discharged. It should be noted here that, since the incineration flue gas is continuously introduced into the reboiler 100 through the connection pipe 610, and heat is transferred to the regeneration exhaust gas in the reboiler 100, thereby obtaining the incineration flue gas in low temperature after heat exchange, the low temperature incineration flue gas may be discharged through the second outlet and transmitted to the chimney 500 to be discharged through the chimney 500. The low-temperature incineration flue gas discharged from the chimney 500 does not contain BTEX and H2S and the like, thereby solving the problem that the regenerated waste gas is directly discharged outside to cause harm to human health and the surrounding environment.
In order to control the gas pressure in the reboiler 100, in some embodiments, the first inlet is connected to the triethylene glycol regeneration tower 400 through a first pipe 620, and a first control valve 710 is disposed on the first pipe 620, and the flow rate of the regeneration waste gas in the first pipe 620 can be adjusted by adjusting the opening degree of the first control valve 710, so that the flow rate of the regeneration waste gas is reasonable.
To achieve automatic control of the gas pressure, the reboiler 100 is provided with a pressure transmitter 810, and the pressure transmitter 810 is in signal connection with the first control valve 710, so that the opening degree of the first control valve 710 can be adjusted by the detection result of the pressure transmitter 810.
Alternatively, the pressure transmitter 810 may be connected to the reboiler 100 with an opening of the pressure transmitter 810 communicating with the inner cavity of the reboiler 100 so that the gas pressure in the inner cavity of the reboiler 100 can be detected by the pressure transmitter 810. Of course, it is also possible to dispose the pressure transmitter 810 inside the housing 110 of the reboiler 100 and perform signal transmission by wireless or wire.
Based on the above arrangement, the gas pressure in the reboiler 100 is detected in real time by the pressure transmitter 810 during the operation of the exhaust gas treatment system; when the gas pressure is greater, such as at and above the first preset value, a signal may be transmitted to the first control valve 710 to decrease the opening of the first control valve 710 to decrease the flow rate of the regeneration off-gas in the first conduit 620; when the gas pressure is small, such as at or below the second preset value, a signal may be transmitted to the first control valve 710 to increase the opening of the first control valve 710 to increase the flow rate of the regeneration off-gas in the first conduit 620. Thus, the above process can achieve detection and automatic adjustment of the gas pressure within the reboiler 100 to ensure that the gas pressure within the reboiler 100 is within a reasonable range.
It should be noted here that, in order to implement automatic control, a control unit may be additionally provided, and the pressure transmitter 810 and the first control valve 710 are both connected to the control unit, so as to receive a pressure detection signal through the control unit and control the opening of the first control valve 710 according to the pressure detection signal.
In order to discharge the low-temperature incineration flue gas generated after heat exchange from the chimney 500 smoothly, in some embodiments, the second outlet is connected to the chimney 500 through a second pipeline 630, and a first induced draft fan 910 and a second control valve 720 are connected in series to the second pipeline 630. In this way, the first induced draft fan 910 can provide power for the flow of the incineration flue gas to overcome the flow resistance of the incineration flue gas, so that the incineration flue gas in the reboiler 100 can be quickly transmitted to the chimney 500 and discharged through the chimney 500; and the second control valve 720 can control the flow of the incineration flue gas after heat exchange in the second pipeline 630 by adjusting the opening degree thereof.
In order to automatically adjust the temperature of the medium inside the reboiler 100, in some embodiments, the reboiler 100 is provided with a first temperature transmitter 820, and the first temperature transmitter 820 is in signal connection with the first induced draft fan 910 and the second control valve 720, respectively.
Optionally, a first temperature transmitter 820 may be connected to the reboiler 100 and extend at least partially into the interior of the reboiler 100 to take temperature measurements of the medium within the reboiler 100. Of course, the first temperature transmitter 820 may also be disposed within the housing 110 of the reboiler 100.
Based on the above arrangement, the temperature of the medium in the reboiler 100 can be detected in real time by the first temperature transmitter 820 during the operation of the exhaust gas treatment system; when the temperature of the medium is high, the frequency of the first induced draft fan 910 can be reduced and the opening degree of the second control valve 720 can be reduced, so that the external discharge amount of the incineration flue gas in the reboiler 100 can be reduced, the flow rate of the incineration flue gas introduced into the reboiler 100 is reduced, and the temperature of the medium in the reboiler 100 is not too high; when the temperature of the medium is lower, the frequency of the first induced draft fan 910 can be increased and the opening degree of the second control valve 720 can be increased, so that the inflow flow rate of the incineration flue gas in the reboiler 100 can be increased, the temperature of the medium in the reboiler 100 is increased, and further more heat is provided for heating the regeneration waste gas. Thus, the above process can achieve detection and automatic adjustment of the temperature of the medium inside the reboiler 100 to ensure that the temperature of the medium inside the reboiler 100 is within a reasonable range.
Alternatively, the temperature of the reboiler 100 medium may be controlled at less than 202 ℃.
It should be noted here that, in order to implement automatic control, a control unit may be further added, and the first temperature transmitter 820 and the second control valve 720 are both connected to the control unit, so as to receive a temperature detection signal through the control unit, and control the frequency of the first induced draft fan 910 and the opening degree of the second control valve 720 according to the temperature detection signal.
To control the flue gas temperature, in some embodiments, the stack 500 includes a flue gas duct 510 and a cooling duct 520, and the flue gas duct 510 is disposed adjacent to the cooling duct 520. The smoke exhaust pipe 510 is connected to the second outlet, so that the incineration flue gas after heat exchange discharged from the second outlet flows to the smoke exhaust pipe 510 and is discharged to the external environment through the smoke exhaust pipe 510. The cooling pipeline 520 is used for introducing cold air to generate heat exchange between the cooling pipeline 520 and the smoke exhaust pipeline 510, so that the effect of cooling the smoke exhaust pipeline 510 is achieved.
Alternatively, the smoke evacuation line 510 and the cooling line 520 may be arranged in parallel and spaced apart by a small distance to facilitate heat exchange; of course, the smoke exhaust pipe 510 may also penetrate through the cooling pipe 520 to form a gap therebetween, so as to introduce cold air into the gap to cool the smoke exhaust pipe 510.
In order to adjust the ventilation of the cooling pipeline 520, in some embodiments, a second induced draft fan 920 and a third control valve 730 are connected in series with the cooling pipeline 520. Therefore, the second induced draft fan 920 can provide the power for flowing the cold wind to overcome the flowing resistance of the cold wind, so that the external cold wind is introduced into the cooling pipeline 520 and is discharged through the cooling pipeline 520. In the process that cold air flows in the cooling pipeline 520, heat exchange is generated between the cold air and the incineration flue gas after heat exchange in the smoke exhaust pipeline 510, so that the temperature of the incineration flue gas can be reduced; also, the third control valve 730 may control the flow rate of the cool air in the cooling pipeline 520 by adjusting its opening degree.
In order to automatically adjust the temperature of the exhaust smoke, in some embodiments, the exhaust smoke pipe 510 is provided with a second temperature transmitter 830, and the second temperature transmitter 830 is in signal connection with a second induced draft fan 920 and a third control valve 730 respectively.
Optionally, a second temperature transmitter 830 may be coupled to the smoke evacuation conduit 510 and extend at least partially inside the smoke evacuation conduit 510. Of course, the second temperature transmitter 830 can also be disposed on the inner wall of the smoke evacuation pipe 510.
Based on the above arrangement, during the operation of the exhaust gas treatment system, the temperature of the incineration flue gas after heat exchange in the smoke evacuation pipeline 510 can be detected in real time by the second temperature transmitter 830; when the temperature of the incineration flue gas is higher, the frequency of the second induced draft fan 920 and the opening degree of the third control valve 730 can be increased, so that the flow of cold air introduced into the cooling pipeline 520 can be increased, the cooling effect on the incineration flue gas can be further improved, and the temperature of the incineration flue gas is not too high; when the temperature of burning the flue gas is lower, can reduce the frequency of second draught fan 920 and reduce the aperture of third control valve 730 to can reduce the flow that lets in the cold wind in cooling tube 520, and then can reduce the cooling effect to burning the flue gas, so that the temperature of burning the flue gas is unlikely to low excessively. Therefore, the detection and automatic adjustment of the incineration flue gas temperature in the smoke exhaust pipeline 510 can be realized, so as to ensure that the incineration flue gas temperature in the smoke exhaust pipeline 510 is within a reasonable range.
Alternatively, the temperature of the incineration flue gases in the flue gas duct 510 may be controlled in a range of less than 400 ℃.
It should be noted here that, in order to implement automatic control, a control unit may be further added, and the second temperature transmitter 830 and the third control valve 730 are both connected to the control unit, so as to receive a temperature detection signal through the control unit, and control the frequency of the second induced draft fan 920 and the opening degree of the third control valve 730 according to the temperature detection signal.
In order to regulate the flow of incineration flue gas to the reboiler 100, in some embodiments, a fourth control valve 740 is provided in the connection duct 610, and the flow of incineration flue gas in the connection duct 610 can be controlled by the fourth control valve 740.

To achieve an automatic control of the temperature of the medium in the reboiler 100, in some embodiments a third temperature transmitter 840 is provided in the reboiler 100, the third temperature transmitter 840 being in signal connection with the fourth control valve 740 and the fifth control valve 750, respectively.
Alternatively, a third temperature transmitter 840 may be connected to the housing 110 of the reboiler 100. Of course, a third temperature transmitter 840 may also be provided within the housing 110.
Based on the above arrangement, the temperature of the medium in the reboiler 100 can be detected in real time by the third temperature transmitter 840 during the operation of the exhaust gas treatment system; when the temperature of the medium in the reboiler 100 is high, the opening degree of the fourth control valve 740 and the opening degree of the fifth control valve 750 may be decreased, so that the flow rate of the incineration flue gas introduced into the reboiler 100 may be decreased, and the temperature of the reboiler 100 may not be too high; when the temperature of the reboiler 100 is low, the opening degree of the fourth control valve 740 and the opening degree of the fifth control valve 750 may be increased, so that the flow rate of the incineration flue gas introduced into the reboiler 100 may be increased, and the temperature of the medium in the reboiler 100 may not be too low. Thus, detection and automatic adjustment of the temperature of the medium inside the reboiler 100 may be achieved to ensure that the temperature of the medium inside the reboiler 100 is within a reasonable range.
Alternatively, the reboiler 100 operating temperature may be controlled at around 196 ℃ to meet practical requirements.
It should be noted here that the first temperature transmitter 820 and the third temperature transmitter 840 can be replaced by a common temperature transmitter, which can reduce the number of parts and cost.

Based on this, under the driving action of the third induced draft fan 930, the external air can enter the gas burner through the fourth pipeline 650 and the combustion air inlet, so as to facilitate the combustion of the regenerated waste gas and make the combustion of the regenerated waste gas more sufficient.
It should be noted that, the third induced draft fan 930 and the second induced draft fan 920 may be replaced by a common induced draft fan, and the common induced draft fan may provide combustion air for the incinerator 300 and cool air for the cooling pipeline 520, and reduce the number of components.
In addition, the gas burner may further have a gas inlet connected to the third pipe 640 to supply gas to the gas burner through the third pipe 640, thereby ensuring more sufficient combustion of the regeneration exhaust gas.
Based on this, the incinerator 300 may be controlled to burn at a temperature ranging from 850 ℃ to 910 ℃.
