Description

Technical Field

[0001] The present invention relates to the field of waste gas treatment equipment, and more specifically, to a VOCs mobile desorption device. Background Art

[0002] Volatile organic compounds, commonly referred to as VOCs, are usually divided into several categories, including non-methane hydrocarbons, oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, and sulfur-containing organic compounds. VOCs participate in the formation of ozone and secondary aerosols in the atmospheric environment, and have an important impact on regional atmospheric ozone pollution and PM2.5 pollution. Most VOCs have a special unpleasant odor and are toxic, irritating, teratogenic and carcinogenic. Benzene, toluene and formaldehyde, in particular, can cause great harm to human health. VOCs are important precursors to urban haze and photochemical smog, and are mainly derived from coal chemical industry, petrochemical industry, fuel coating manufacturing, solvent manufacturing and use, and other processes. The adsorption tower is a device for purifying VOCs components in exhaust gas, and is mainly composed of a tower body and an adsorbent. After the adsorbent is saturated with adsorption, a desorption device is required to regenerate the adsorbent.

Due to the nature of the desorption work, the VOCs desorption equipment is idle most of the time and only works when the adsorbent needs to be regenerated.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] ① Through the carrying transporter, the VOCs mobile desorption equipment can be moved on demand, so that manufacturers can rent out the VOCs mobile desorption equipment they own, which helps to improve the utilization rate and reduce the cost of use. Through the rapid vaporization mechanism, the VOCs mobile desorption equipment can quickly generate steam, with lower energy consumption and reduced waiting time, which helps to further reduce the cost of use. Through the steam transmission component, the VOCs mobile desorption equipment can directly inject hot steam into the adsorption tower for desorption, and there is no need to clean out the adsorbent for desorption, which saves more time and effort, helps to reduce the cost of use again, and improves the practicality of the VOCs mobile desorption equipment.

[0020] ② The desorbed mixed gas in the adsorption tower can be led out through the tail gas discharge mechanism, and the desorbed mixed gas can be powered by the boosting mechanism so that the desorbed mixed gas can flow out of the adsorption tower. The pressure-changing interceptor can form a negative pressure environment in the adsorption tower, which helps to speed up the desorption speed, make the VOCs mobile desorption equipment more efficient, and help reduce the use cost of the VOCs mobile desorption equipment. The desorbed mixed gas can be charged into the temporary liquefaction mechanism through the boosting mechanism, and the desorbed mixed gas can exist in the temporary liquefaction mechanism in the form of high pressure through the pressure-maintaining overflow mechanism, which helps to liquefy the desorbed mixed gas so that people can recycle the relevant components, which helps to further reduce the cost of the VOCs mobile desorption equipment. The use cost of the VOCs mobile desorption equipment can be reduced by using the temporary liquefaction mechanism, so that the desorbed mixed gas can stay in the high-pressure environment for a long enough time, thereby avoiding the discharge of the desorbed mixed gas that has just entered, increasing the recovery rate, and helping to reduce the use cost of the VOCs mobile desorption equipment again. The temperature of the internal environment of the temporary liquefaction mechanism can be reduced by the refrigeration cooler, so that the liquefaction speed can be faster, thereby making the VOCs mobile desorption equipment more efficient and less expensive to use. The treated exhaust gas can be passed into the adsorption tower in use through the pressure-maintaining overflow mechanism to purify the residual VOCs components in the exhaust gas, thereby avoiding the discharge of VOCs components and polluting the environment, thereby improving the practicability of the VOCs mobile desorption equipment.

[0043] Working principle:

[0044] First, move the VOCs mobile desorption equipment to the location where desorption is required and open the opening and closing flip door 103, then pull out the pressure transformer interceptor 4 from the inside of the steam transmission inner pipe 31, and then slide the pressure transformer interceptor 4 with the isolation piston tube 34 through the rubber hose 35 inside the steam transmission inner pipe 31, and then use bolts to connect the splicing flange 403 with the air inlet on the adsorption tower, so that the pressure transformer transport tank 404 is connected to the air inlet, and then pull out the docking plug 57 from the inside of the exhaust emission inner pipe 51 through the docking opening tube 58, and then slide the docking plug 57 with the isolation plug tube 54 through the elastic hose 55 inside the exhaust emission inner pipe 51, and then use bolts to connect the assembling flange 59 with the air outlet on the adsorption tower, so that the docking opening tube 58 is connected to the air outlet. The quick connector 807 is connected, and then the quick connector 807 is pulled, and then the quick connector 807 pulls the overflow hose 806, and then the overflow hose 806 is released from the outside of the rotating cylinder 803 and drives it to rotate, and then the rotating cylinder 803 works on the power storage spring 804, and then the elastic potential energy of the power storage spring 804 increases, and then the quick connector 807 is connected to another adsorption tower in use. At this time, the quick connector 807 is connected to the branch pipe on the air inlet pipeline of the adsorption tower, and then the thermostat 207 is turned on, and then the thermostat 207 controls the inclined heating plate 206 to heat up, and then the temperature of the surface of the inclined heating plate 206 gradually increases, and then the submersible small pump 212 is turned on, and then the vaporized water body 110 is driven by the submersible small pump 212 through the bending lifting pipe 20 9 enters the transfer cylinder 210 and is sprayed out from the spraying holes 211, and then the sprayed vaporized water body 110 falls on the surface of the inclined heating plate 206, and then the vaporized water body 110 falling on the surface of the inclined heating plate 206 absorbs heat and quickly vaporizes into high-temperature steam, and then the booster motor 62 is turned on, and then the booster motor 62 drives the piston pump assembly 63 to run, and then the analyzed mixed gas inside the adsorption tower passes through the docking opening cylinder 58, the elastic hose 55, the partition sliding plug tube 54, the exhaust gas exhaust inner tube 51, the piston pump assembly 63, and the steam introduction pipe 64 under the drive of the piston pump assembly 63 to enter the first independent chamber, and then the air pressure inside the adsorption tower is reduced, and then the variable pressure retention piston 409 moves to the left under the action of the pressure difference and pulls the variable pressure retention spring 408, and then the variable pressure The pressure retention spring 408 elastically stretches, and the elastic potential energy increases, and then the variable pressure retention piston 409 contacts the limiting protrusion 405. At this time, the variable pressure steering spray hole 411 is connected with the tapered groove 406. After that, the high-temperature steam inside the thermal insulation box 203 is driven by the pressure difference through the steam transmission inner pipe 31, the isolation piston tube 34, the rubber hose 35, the variable pressure retention chamber 407, the variable pressure steering groove 410, and the variable pressure steering spray hole 411 to enter the tapered groove 406 and enter the adsorption tower through the variable pressure transport tank 404, and the absorbent inside the adsorption tower is heated and desorbed. Then, the desorbed mixed gas entering the first independent chamber enters the second independent chamber through the one-way diaphragm valve 76 driven by the pressure difference, and the gas in the second independent chamber enters the third independent chamber through the one-way diaphragm valve 76.The gas in the third independent chamber enters the fourth independent chamber through the one-way diaphragm valve 76, the gas in the fourth independent chamber enters the fifth independent chamber through the one-way diaphragm valve 76, the gas in the fifth independent chamber enters the sixth independent chamber through the one-way diaphragm valve 76, the gas in the sixth independent chamber enters the seventh independent chamber through the one-way diaphragm valve 76, the gas in the seventh independent chamber enters the eighth independent chamber through the one-way diaphragm valve 76, and the gas pressure inside the independent chamber gradually increases, and then the components in the desorbed mixed gas are gradually liquefied, and then the refrigeration and cooling machine 91 is turned on, and then the coolant circulates inside the heat absorption circulation pipe 92, and then the liquefied chamber 7 3, the temperature inside is lowered to increase the liquefaction speed, and then the liquefied components drip into the sealing liquid 75. Then, as the air pressure inside the liquefaction chamber 73 increases, the air pressure difference on both sides of the pressure-maintaining cone plug 813 gradually increases. Then, the pressure-maintaining cone plug 813 moves to the left under the action of the air pressure difference, and then the tapered through hole 816 is opened. Then, the exhaust gas inside the eighth independent chamber passes through the tapered through hole 816, the pressure-maintaining column cavity 809, the pressure-maintaining through hole 811, the overflow elbow 801, the rotary joint 802, the rotary cylinder 803, the overflow hose 806, and the quick connector 807 into the adsorption tower in the use state. The adsorbent in the state adsorption tower purifies the relevant components remaining in the exhaust gas. Then, when the proportion of the target components in the mixed desorbed gas reaches the requirement, the temperature controller 207, the submersible pump 212, the booster motor 62, and the refrigeration and cooling machine 91 are turned off, and then the solution discharge valve 78 is opened, and then the sealing liquid 75 is discharged through the solution discharge pipe 77, and then the relevant components in the sealing liquid 75 are recovered, and then the splicing flange 403 and the assembling flange 59 are removed from the adsorption tower, and then the rubber hose 35 is thrusted by the pressure transformer interceptor 4, and then the rubber hose 35 is brought with the isolation piston tube 34 in the inner steam transmission inner pipe 31. The rotating cylinder 803 is rotated in the opposite direction until the pressure-changing interception plug 401 is inserted into the steam transmission inner tube 31, and then the elastic hose 55 is pushed through the docking opening tube 58, and then the elastic hose 55 slides with the partition plug tube 54 inside the exhaust gas exhaust inner tube 51 until the docking plug 57 is inserted into the exhaust gas exhaust inner tube 51, and then the quick connector 807 is removed, and then the power storage spring 804 applies a torsional force to the rotating cylinder 803, and then the rotating cylinder 803 rotates in the opposite direction, and then the overflow hose 806 is wound around the outside of the rotating cylinder 803 to retract the overflow hose 806, and then the opening and closing flip door 103 is closed.
