Abstract
Description
Technical Field
[0001] This utility model relates to the field of volatile gas treatment technology, specifically a VOC condensation and recovery device. Background Technology
[0002] VOC is an abbreviation for volatile organic compounds. In a general sense, VOC refers to volatile organic compounds; however, in an environmental context, it refers to a more reactive type of volatile organic compound—the kind that can cause harm. Therefore, VOCs need to be purified before being emitted.
[0003] In existing technologies, VOC purification processes involve using a cold source to condense and collect harmful substances from the VOCs. However, when the cold source exchanges heat with the VOC airflow, the rapid temperature drop of the VOC airflow can easily lead to frost formation, thus reducing the processing speed and even causing blockages, ultimately affecting the VOC purification process. Utility Model Content
[0004] In view of the above situation and to overcome the existing defects, this utility model provides a VOC condensation and recovery device.
[0005] This utility model provides the following technical solution: A VOC condensation recovery device is proposed, comprising a condensation chamber, an insulation plate inside the condensation chamber, a cooling structure on the side of the condensation chamber, a pre-cooling component at the upper end of the condensation chamber, the pre-cooling component being positioned above the insulation plate, one end of the pre-cooling component being located inside the condensation chamber and the other end being located on the upper side of the condensation chamber away from the cooling structure, and a condensation component at the lower end of the condensation chamber; the pre-cooling component includes a control pipe, which is evenly distributed below the upper wall of the condensation chamber, and a control rod is movably disposed within the control pipe, one end of the control rod being located inside the control pipe and the other end penetrating the side wall of the condensation chamber and exiting outside the condensation chamber; an air inlet pipe is provided on the condensation chamber, the air outlet of the air inlet pipe being located above the insulation plate inside the condensation chamber; air outlet holes are evenly distributed on the lower wall of the control pipe, and a one-way valve is disposed within each air outlet hole; a clamp is provided on the upper side of the condensation chamber away from the cooling structure; and a temperature monitoring device is provided on the upper side wall of the condensation chamber.
[0006] Furthermore, the clamping device includes a support plate located on the upper side of the condensing chamber away from the cooling structure. Springs are evenly distributed on the support plate, with a pull plate on each spring and a fixing rod below the pull plate. The fixing rod passes through the springs, and one end of the fixing rod away from the pull plate is movably inserted through the support plate and positioned below it. The control rod has evenly distributed slots. The cooling structure supplies cold air to the control tube. The cold air flows through an outlet and a one-way valve (controlling the gas to only exit from the control tube) to the area above the insulation plate in the condensing chamber. A temperature monitoring device monitors the temperature above the insulation plate. When the temperature above the insulation plate is high, the pull plate is pulled, putting the spring in a stretched state. The pull plate moves the fixing rod upwards, dislodging it from the slot. Pulling the control rod allows more cold air to flow into the control tube. When the temperature monitoring device shows the temperature meets the requirements, the pull plate is released. Under the spring's rebound force, the pull plate moves downwards, carrying the fixing rod downwards, inserting it into the slot, thus fixing the control rod.
[0007] The condensing assembly includes a vent pipe, one end of which is located below a heat insulation plate, and the other end of which is located below a control pipe. A second one-way valve is installed inside the vent pipe. Two sets of slide rails are symmetrically arranged below the heat insulation plate, with the other set located on the lower wall of the condensing chamber. Magnetic plates are movably mounted on the slide rails, and connecting rods are evenly connected between the magnetic plates. Dispersing plates are installed between the connecting rods. Energized coils are evenly arranged on the lower side of the condensing chamber away from the cooling structure. Gas flows through the vent pipe and the second one-way valve (control valve). Gas can only enter from above the insulation board to below it. When the gas enters below the insulation board, an electric coil is energized, generating a magnetic field around the coil. This magnetic field attracts a magnetic plate, which, via a connecting rod, moves a dispersing plate closer to the coil. Then, when the coil is energized again, the magnetic field around it repels the magnetic plate, causing it to move away from the coil. This process is repeated, causing the dispersing plate to move back and forth, increasing airflow below the insulation board and preventing localized low temperatures that could cause the gas to cool down too quickly and frost to form.
[0008] Preferably, the cooling structure includes a cold source distribution chamber located on the side of the condensing chamber away from the card. A cold air fan is connected to the cold source distribution chamber. An air inlet is provided at the upper side of the condensing chamber and connected to the cold source distribution chamber and a control pipe. An air inlet is provided at the lower side of the condensing chamber and connected to the cold source distribution chamber. The air inlet is located below the heat insulation plate. During the cooling process, the cold air fan is turned on to input cold air into the cold source distribution chamber. The cold air enters the control pipe through the air inlet and simultaneously enters the area below the heat insulation plate in the condensing chamber through the air inlet, providing cold air for the pre-cooling and condensing components.
[0009] Furthermore, the lower end of the side of the condensing chamber adjacent to the cooling structure is detachably provided with a disassembly plate, which facilitates the removal of the condensed liquid from the condensing chamber.
[0010] The air inlet pipe and the vent pipe are located at both ends of the condensing chamber. The lowest point of the air inlet pipe is lower than the highest point of the vent pipe. This allows the gas to flow through the air inlet pipe into the condensing chamber, enabling better pre-cooling of the gas.
[0011] The VOC condensation and recovery equipment proposed by this utility model, which adopts the above structure, has the following beneficial effects:
[0012] 1. By setting up the pre-cooling component, the temperature of the gas suddenly drops after entering the condensing component, which could lead to frosting and ensure the normal condensation process of the gas.
[0013] 2. The condenser assembly, in conjunction with the precooling assembly, increases airflow under the insulation panel, preventing localized temperatures from dropping too low and causing the gas to cool down too quickly, thus further preventing frost formation.
[0014] 3. The design of the disassembly plate facilitates the removal of condensed liquid from the condensation chamber.
[0015] 4. The intake pipe and the vent pipe are located at both ends of the condenser, and the lowest point of the intake pipe is lower than the highest point of the vent pipe. This allows the gas to flow through the intake pipe into the condenser, enabling better pre-cooling. Attached Figure Description

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a VOC condensation recovery device, including a condensation chamber 1, an insulation plate 2 inside the condensation chamber 1, a cooling structure 3 on the side of the condensation chamber 1, a pre-cooling component 4 at the upper end of the condensation chamber 1, the pre-cooling component 4 being located above the insulation plate 2, one end of the pre-cooling component 4 being located inside the condensation chamber 1 and the other end being located at the upper end of the side of the condensation chamber 1 away from the cooling structure 3, a condensation component 5 at the lower end of the condensation chamber 1, and a detachable disassembly plate 29 being detachably provided at the lower end of the side of the condensation chamber 1 adjacent to the cooling structure 3; the pre-cooling component 4 includes a control pipe. 6. Control pipes 6 are evenly distributed on the lower part of the upper wall of the condensing chamber 1. A control rod 7 is movably installed inside the control pipe 6. One end of the control rod 7 is located inside the control pipe 6 and the other end passes through the side wall of the condensing chamber 1 and is located outside the condensing chamber 1. An air inlet pipe 9 is provided on the condensing chamber 1. The air outlet of the air inlet pipe 9 is located above the heat insulation plate 2 inside the condensing chamber 1. Air outlet holes 10 are evenly distributed on the lower wall of the control pipe 6. A one-way valve 11 is installed inside the air outlet hole 10. A clamp 8 is provided on the upper part of the side of the condensing chamber 1 away from the cooling structure 3. A temperature monitoring device 12 is provided on the upper part of the inner side wall of the condensing chamber 1.
[0025] like Figure 1 , Figure 2 , Figure 3As shown, the clip 8 includes a support plate 13, which is located on the upper side of the condensing chamber 1 away from the cooling structure 3. Springs 14 are evenly arranged on the support plate 13, and a pull plate 15 is provided on the springs 14. A fixing rod 16 is provided below the pull plate 15. The fixing rod 16 passes through the springs 14. The end of the fixing rod 16 away from the pull plate 15 can move through the support plate 13 and is located below the support plate 13. The control rod 7 is evenly arranged with slots 17. The air inlet pipe 9 and the vent pipe 18 are located at both ends of the condensing chamber 1. The lowest position of the air inlet pipe 9 is lower than the highest position of the vent pipe 18.
[0026] like Figure 1 , Figure 4 As shown, the condenser assembly 5 includes a vent pipe 18. One end of the vent pipe 18 is located below the heat insulation plate 2, and the other end of the vent pipe 18 is located below the control pipe 6. A one-way valve 19 is installed inside the vent pipe 18. Slide rails 20 are symmetrically arranged below the heat insulation plate 2. There are two sets of slide rails 20. The other set of slide rails 20 is located on the lower wall of the condenser chamber 1. Magnetic plates 21 are movably arranged on the slide rails 20. Connecting rods 22 are evenly connected between the magnetic plates 21. Dispersing plates 23 are provided between the connecting rods 22. Energized coils 24 are evenly arranged on the lower side of the condenser chamber 1 away from the cooling structure 3.
[0027] like Figure 1 As shown, the cooling structure 3 includes a cold source distribution chamber 25, which is located on the side of the condensing chamber 1 away from the card 8. A cold air fan 26 is connected to the cold source distribution chamber 25. An air inlet 27 is provided at the upper end of the side of the condensing chamber 1 and is connected to the cold source distribution chamber 25 and the control pipe 6. An air inlet 28 is provided at the lower end of the side of the condensing chamber 1 and is connected to the cold source distribution chamber 25. The air inlet 28 is located below the heat insulation plate 2.
[0028] In practical use, during the cooling process, the air cooler 26 is turned on, and cold air is introduced into the cold source distribution chamber 25. The cold air enters the control pipe 6 through the air inlet 27, and simultaneously enters the condenser chamber 1 below the heat insulation plate 2 through the air inlet 28. The cold air then flows through the air outlet 10 and the one-way valve 11 (which controls the gas to only exit from the control pipe 6) to the top of the heat insulation plate 2 in the condenser chamber 1. The temperature monitoring device 12 monitors the temperature above the heat insulation plate 2. When the temperature above the heat insulation plate 2 is high, the pull plate 15 is pulled. At this time, the spring 14 is in a stretched state, and the pull plate 15 moves upward with the fixing rod 16, causing the fixing rod 16 to move out of the slot 17. The control rod 7 is then pulled, allowing more cold air to flow into the control pipe 6. When the temperature monitoring device 12 shows that the temperature meets the requirements, the pull plate 15 is released. Under the action of the spring 14's rebound force, the pull plate 15 moves downward with the fixing rod 16, causing the fixing rod 16 to move downward. Insert the 6 into the slot 17 to fix the control lever 7. As the gas flows in, the pressure above the heat insulation plate 2 in the condensing chamber 1 increases. The gas flows into the vent pipe 18 and through the vent pipe 18 and the one-way valve 19 (which controls the gas to only enter from above the heat insulation plate 2 to below the heat insulation plate 2) to condense. The energized coil 24 is energized, and a magnetic field is generated around the energized coil 24, which attracts the magnetic plate 21. The magnetic plate 21 moves the dispersing plate 23 towards the energized coil 24 via the connecting rod 22. Then, the energized coil 24 is energized in the opposite direction. The magnetic field around the energized coil 24 generates a repulsive force on the magnetic plate 21, causing the magnetic plate 21 to move away from the energized coil 24 via the connecting rod 22. The above operation is repeated, causing the dispersing plate 23 to move back and forth, increasing the airflow below the heat insulation plate 2, and preventing the local temperature from getting too low, which would cause the gas to cool down too quickly and frost to form.
