It should be clear that the described embodiments are only some of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model protection.

[0018] As Figs. 1-3 Indicated, in some illustrative embodiments, a large movable unpowered prying block device in VOCs treatment is provided, which is used for VOCs treatment of sewage pool and sewage tank in refinery and petrochemical plant area, and specifically comprises: a movable casing 100, an oil and water removal tank 200, a desulfurization tank 300, an adsorption tank 400, an adjusting structure 500, a butt joint structure 600 and an air outlet structure 700.

[0019] Three independent processing cavities are arranged in the movable casing 100, which are a pretreatment cavity 101, a desulfurization cavity 102 and an adsorption cavity 103, the pretreatment cavity 101 is close to the sewage pool / sewage tank, and the exhaust gas is discharged after sequentially passing through the pretreatment cavity 101, the desulfurization cavity 102 and the adsorption cavity 103.

[0020] The oil and water removal tank 200 and the adjusting structure 500 are arranged in the pretreatment cavity 101. The oil and water removal tank 200 is used for removing oil and moisture in the exhaust gas, and can adopt a wire mesh mist eliminator as the core filter material, the wire mesh mist eliminator has high oil and water removal capacity, can intercept and separate small oil droplets and water droplets in the exhaust gas, so as to purify the gas. The adjusting structure 500 is used for adjusting the position of the oil and water removal tank 200, so that it can directly face the exhaust gas flow from the sewage pool or the sewage tank, that is, through the adjusting structure 500, the operator can change the position of the oil and water removal tank 200 according to actual needs, so that it can be butt jointed with the sewage pool or the sewage tank in different working conditions and environments, and then it is ensured that no matter from which position the exhaust gas enters the pretreatment cavity 101, the oil and water removal tank 200 can intercept and remove oil and moisture in the most efficient way.

[0021] The adjusting structure 500 comprises a lifter 510, a bracket 520, a flow equalizing plate 530 and a valve port. The valve port comprises a valve port main body 540 and a mounting port 550.

[0022] The bracket 520 is arranged on the lifter 510, and the oil and water removal tank 200 is arranged on the bracket 520. The lifter 510 is designed so that the operator can move the bracket 520 up and down as needed, thereby adjusting the height and position of the oil and water removal tank 200 to adapt to the sewage pool or sewage tank under different conditions. The bracket 520 provides a stable support platform for the oil and water removal tank 200, so that the oil and water removal tank 200 can be conveniently installed, maintained and replaced. The valve port is arranged on the bracket 520 and connected with the air inlet of the oil and water removal tank 200. Specifically, the air inlet of the oil and water removal tank 200 is connected with the valve port body 540. One side of the valve port body 540 is connected with the bracket 520, and the other side of the valve port body 540 is gradually tapered and connected with the mounting port 550. The design of the mounting port 550 enables it to be quickly connected with the docking structure 600, thereby realizing the docking with the exhaust gas discharge system of the sewage pool or sewage tank. The flow uniformizing plate 530 is arranged in the valve port body 540, so that the airflow entering the oil and water removal tank 200 is more uniform, thereby improving the efficiency of oil and water removal. Moreover, the flow uniformizing plate 530 can prevent vortex or local high-speed area when the airflow passes through the valve port, which not only optimizes the performance of the oil and water removal tank 200, but also prolongs its service life.

[0023] A hollow groove is formed in the side wall plate of one side of the mobile casing 100, and the docking structure 600 is arranged in the hollow groove, thereby providing space for the installation and operation of the docking structure 600. The docking structure 600 includes a clamping ring 610, a telescopic docking pipe port 620, an upper telescopic corrugated plate 630 and a lower telescopic corrugated plate 640. The telescopic docking pipe port 620 is arranged in the clamping ring 610, and the up-down movement of the clamping ring 610 enables the docking structure to be accurately adjusted according to the specific position and height of the sewage pool / sewage tank. The upper telescopic corrugated plate 630, the clamping ring 610 and the lower telescopic corrugated plate 640 are sequentially installed in the hollow groove from top to bottom through guide rails, so that the hollow groove is always in a closed state when the clamping ring 610 moves up and down to adjust the position in the hollow groove.

[0024] One end of the telescopic docking pipe port 620 is connected with the mounting port 550 of the valve port, the air inlet of the oil and water removal tank 200 is connected with the telescopic docking pipe port 620 through the valve port body 540 and the mounting port 550, and the other end of the telescopic docking pipe port 620 is connected with the sewage pool exhaust gas output pipeline, so that the mobile casing 100 can be quickly and effectively docked with the exhaust gas output system of the sewage pool, thereby realizing the collection and treatment of exhaust gas.

[0025] The telescopic butt joint pipe port 620 can adopt a sleeve type structure, which is composed of a plurality of sleeves that can slide relative to each other, and the butt joint is realized by relative sliding of the sleeves. Alternatively, the telescopic butt joint pipe port 620 can adopt a threaded connection form, and the butt joint is realized by rotating to lengthen or shorten the pipe port.

[0026] The bottom of the chamber wall between the pretreatment chamber 101 and the desulfurization chamber 102 is provided with an air channel 104. The air channel 104 serves to connect the two chambers, so that the exhaust gas flows from the pretreatment chamber 101 to the desulfurization chamber 102 during the treatment process. The adjustment structure further comprises a sealing plate 560, the bottom end of the sealing plate 560 being connected to the bracket 520, and the sealing plate 560 being movable along with the bracket 520. The top end of the sealing plate 560 is provided with a dynamic sealing rubber sheet 570, which is in contact with the chamber wall between the pretreatment chamber 101 and the desulfurization chamber 102, so that the exhaust gas discharged from the oil and water removal tank 200 can smoothly enter the desulfurization chamber 102, preventing the gas from flowing during the treatment process.

[0027] The desulfurization tank 300 is arranged in the desulfurization chamber 102, and the adsorption tank 400 is arranged in the adsorption chamber 103. The main function of the desulfurization tank 300 is to remove sulfides in the exhaust gas, and the hydrogen sulfide can be removed by adsorption or chemical methods, such as zinc oxide or other desulfurizing agents. The adsorption tank 400 is used for further purifying the exhaust gas and capturing and adsorbing VOCs gas.

[0028] The air outlet structure 700 is arranged on the side wall plate on the other side of the mobile casing 100. The air outlet structure 700 comprises an air outlet window 710, an output pipeline 720, a discharge pipeline 730, and a sampling pipeline 740. The output pipeline 720 is connected to the air outlet window 710, the discharge pipeline 730 is connected to the output pipeline 720, and the sampling pipeline 740 is arranged on the discharge pipeline 730. The design of the air outlet structure 700 takes into account the effective discharge of the exhaust gas, the safety of the system, and the needs of environmental monitoring. Through this structure, it can be ensured that the treated exhaust gas meets the environmental protection requirements before being discharged, and at the same time, it provides convenience for the operation and maintenance of the system.

[0029] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
