[0078] Specifically, the treatment device further comprises a reflux pipeline, one end of the reflux pipeline is in communication with the desorption gas reflux end of the cyclic adsorption and desorption device 400, and the other end is in communication with the air inlet pipeline.

[0079] When the concentration of the gas purified by the cyclic adsorption and desorption device 400 is greater than the set value of the second waste gas concentration monitor 202, the gas is circulated and purified again by the cyclic adsorption and desorption device 400 through the reflux pipeline.

[0082] In a more specific embodiment as shown Figure 1 The air inlet pipeline is connected with a slow-release tank 500, which is arranged between the first variable frequency air pump 101 and the first exhaust gas concentration monitor 201.

[0083] More specifically, the slow-release tank 500 is filled with activated carbon particles, and the iodine value of the activated carbon particles is greater than 800 mg / g. Including but not limited to 800 mg / g, 830 mg / g, 870 mg / g, 900 mg / g, 1000 mg / g, 1320 mg / g, which are not listed one by one here.

[0084] More specifically, the slow-release tank 500 further comprises a first electric heating device 510 and a third power module, the third power module is connected with the first electric heating device 510 and used to supply power to the first electric heating device 510.

[0085] In the later stage of treatment, when the first exhaust gas concentration monitor 201 detects that the concentration of organic exhaust gas is low in real time, the first electric heating device 510 is turned on through the automatic control system 700, so that the organic exhaust gas previously "stored" in the slow-release tank 500 is desorbed and continues to be treated, so that the concentration of organic exhaust gas in the whole system does not become too high, and the overall level is kept stable, so as to prolong the service life of the organic exhaust gas moving skid-mounted treatment device 1.

[0086] Specifically, the air inlet pipeline is provided with a first valve 601, and the first valve 601 is located between the first variable frequency air pump 101 and the slow-release tank 500.

[0087] As shown in Figure 1As shown, in a specific embodiment, the cascade condensation recovery device 300 includes a primary heat exchange component, a secondary condensation component, a tertiary cryogenic component, and a fourth power module. The primary heat exchange component, secondary condensation component, and tertiary cryogenic component are used for gradient condensation of the organic waste gas. The inlet end of the primary heat exchange component is connected to the inlet pipe, the outlet end of the primary heat exchange component is connected to the inlet end of the secondary condensation component, and the outlet end of the secondary condensation component is connected to the inlet end of the tertiary cryogenic component. The fourth power module is connected to the primary heat exchange component, secondary condensation component, and tertiary cryogenic component to supply power to them. The fourth power module includes, but is not limited to, dry cell batteries and energy storage batteries; any structure capable of storing energy and providing power is applicable.

[0088] When organic waste gas enters the cascade condensation and recovery device 300, it can be condensed and recovered by selectively using one or more of the first-stage heat exchange components, the second-stage condensation components, and the third-stage cryogenic components, depending on the material composition of the organic waste gas.

The liquid outlet of the three-stage heat exchanger 330 is connected to the three-stage liquid recovery tank 332 through the third liquid recovery pipeline, and the third variable frequency water pump 331 is located in the third liquid recovery pipeline.

[0093] Specifically, the fourth power module is connected with the first heat exchanger 310, the first variable frequency water pump 311, the second heat exchanger 320, the second variable frequency water pump 321, the third heat exchanger 330 and the third variable frequency water pump 331 for power supply.

[0094] Specifically, the gas outlet of the first heat exchanger 310 is connected with the communication pipeline through a first channel, and a first switch is arranged on the first channel.

[0095] Specifically, the gas outlet of the second heat exchanger 320 is connected with the communication pipeline through a second channel, and a second switch is arranged on the second channel.

[0096] Specifically, the gas outlet of the third heat exchanger 330 is connected with the communication pipeline through a third channel.

[0097] Specifically, the first heat exchanger 310 further comprises a second valve 602.

[0098] Specifically, the second heat exchanger 320 further comprises a third valve 603.

[0099] Specifically, the third heat exchanger 330 further comprises a fourth valve 604.

[0100] In actual use, the organic waste gas mobile skid-mounted treatment device selects one or more of the first heat exchange assembly, the second condensation assembly and the third deep cooling assembly for treatment according to the type of the organic waste gas, and the three assemblies can be independently operated.

[0101] When only the first heat exchange assembly is used, the second valve 602 and the third valve 603 are closed, and the first switch is opened, so that the organic waste gas directly enters the communication pipeline through the first channel after passing through the first heat exchange assembly; when the first heat exchange assembly and the second condensation assembly are used, the first switch and the fourth valve 604 are closed, the second valve 602, the third valve 603 and the second switch are opened, so that the organic waste gas directly enters the communication pipeline through the second channel after passing through the first heat exchange assembly and the second condensation assembly; when the three assemblies are used, the first switch and the second switch are closed, the second valve 602, the third valve 603, the fourth valve 604 and the third switch are opened, so that the organic waste gas directly enters the communication pipeline through the third channel after passing through the first heat exchange assembly, the second condensation assembly and the third deep cooling assembly.

[0104] In another specific embodiment, non-metallic packing is used in the primary heat exchanger 310, the secondary heat exchanger 320, and the tertiary heat exchanger 330. The non-metallic packing increases the condensation surface area, improves condensation efficiency, and also makes the condensation process more uniform. More specifically, the non-metallic packing is flame-retardant polyvinyl chloride (PVC).

[0105] Specifically, the primary heat exchanger is suitable for processing materials with a freezing point of 0 to 15°C. Organic materials at this freezing point are liquefied from gas and then pumped to the primary recovery tank 312 by the first variable frequency water pump 311. The secondary condensation unit is suitable for processing materials with a freezing point of -75 to 0°C. Organic materials at this freezing point are liquefied from gas and then pumped to the secondary recovery tank 322 by the second variable frequency water pump 321. The tertiary cryogenic unit is suitable for processing materials with a freezing point of -100 to -75°C.

The fifth power module includes, but is not limited to, dry batteries and energy storage batteries; any structure that can store energy and provide power is applicable. The circulating adsorption-desorption device 400 further purifies the waste gas that has passed through the cascade condensation and recovery device 300.

[0118] In actual use, after the organic waste gas passes through the cascade condensation recovery device 300, most of the organic components are recovered and utilized, and the remaining organic waste gas enters the circulating adsorption-desorption device 400 under the action of the second variable frequency air pump 102. At this time, the fifth valve 605 and the seventh valve 607 are in the open state, and the sixth valve 606 and the ninth valve 609 are in the closed state, so that the organic waste gas enters the first adsorption-desorption fixed bed 410 through the first adsorption pipe and is purified, and then enters the exhaust pipe through the first purification pipe. The second waste gas concentration monitor 202 monitors the waste gas concentration in real time to observe whether the ecological environment emission requirement (non-methane total hydrocarbon (NMHC) <30 mg / m 3 ) is met.

[0119] When the ecological environment emission requirement cannot be met, it means that the first adsorption-desorption fixed bed 410 reaches a saturated state. At this time, the automatic control system 700 receives instructions to close the fifth valve 605, the seventh valve 607 and the tenth valve 610, and to open the sixth valve 606, the eighth valve 608 and the ninth valve 609, so that the organic waste gas enters the second adsorption-desorption fixed bed 420 for purification treatment through the second adsorption pipe; at the same time, the second electric heating device 411 is opened, so that the saturated first adsorption-desorption fixed bed 410 is desorbed, and the desorbed organic waste gas enters the reflux pipe through the first desorption gas reflux pipe. Under the action of the third variable frequency air pump 103, the organic waste gas enters the cascade condensation recovery device 300 again through the gas inlet pipe for cyclic purification treatment.

[0120] Similarly, when the second adsorption-desorption fixed bed 420 reaches a saturated state, the automatic control system 700 receives instructions to close the sixth valve 606, the eighth valve 608 and the ninth valve 609, and to open the fifth valve 605, the seventh valve 607 and the tenth valve 610, so as to realize the switching of the first adsorption-desorption fixed bed 410 and the second adsorption-desorption fixed bed 420. The cycle is repeated until the second waste gas concentration monitor 202 monitors that the waste gas concentration in the exhaust pipe meets the ecological environment emission requirement.

[0126] As shown in Figure 3 The application also provides an organic waste gas mobile skid-mounted control system, which at least comprises an upper computer 2 and an organic waste gas mobile skid-mounted treatment device 1 as described above.

[0127] The upper computer 2 communicates wirelessly with the organic waste gas mobile skid-mounted treatment device 1, provides control instructions for the organic waste gas mobile skid-mounted treatment device 1, and also obtains and displays detected data. The upper computer 2 includes but is not limited to a computer, a mobile phone and a tablet computer;It can realize real-time presentation, sharing and second-level synchronization of APP-PC multi-end data. The information displayed by the upper computer 2 includes but is not limited to the heating area and heating power of the electric heating device, the air pump motor power, the organic waste gas concentration and the alarm information whether it meets the standard.

[0128] The working principle of the organic waste gas mobile skid-mounted treatment device provided by the application is as follows:
