Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a combined VOCs adsorption cabinet. Background Art

[0002] VOCs is the abbreviation of volatile organic compounds, which refers to organic compounds with a saturated vapor pressure greater than 70Pa at room temperature and a boiling point below 260°C at normal pressure. VOCs react with nitrogen dioxide in the atmosphere under the action of light and heat to form ozone, resulting in photochemical smog and pungent odors. These substances can irritate the eyes and respiratory tract, damage the heart, lungs, liver and other important organs, and long-term exposure may even lead to cancer. Therefore, it is necessary to treat VOCs in exhaust gas.

[0003] In the prior art, VOCs are usually treated by adsorption. However, the temperature, pressure and flow rate during the adsorption process will affect the adsorption effect. The current conventional VOCs treatment devices have poor control over the above conditions, resulting in poor adsorption effect.

[0022] The beneficial effects of the present invention are:

[0023] 1. In the present invention, the combined VOCs adsorption cabinet introduces the waste gas containing VOCs into the feed square tube through the introduction pipe, and a part of the waste gas is introduced into the temporary storage box under the guidance of the guide inclined plate for temporary storage, and the VOCs in the waste gas are adsorbed by the second adsorption member, and the sealing plate is pushed to move by the waste gas, and the other part of the waste gas flows to the left through the gap between the guide inclined plate and the inner wall of the feed square tube, and is led out from the left end of the feed square tube, and the VOCs are further adsorbed by the fourth adsorption member;

[0024] 2. In the present invention, the combined VOCs adsorption cabinet described above drives the rotating disk to rotate counterclockwise by starting the driving motor. When the rotating disk rotates, the connecting column enters the compression section, adsorption section, exhaust section and intake section in sequence. The connecting column moves vertically downward in the intake section, and drives the piston plate downward through the U-shaped rod, so that negative pressure is formed in the compression box, and the exhaust gas enters the compression box through the air inlet cylinder. The first adsorption component and the third adsorption component adsorb the VOCs in the exhaust gas. The connecting column moves vertically upward in the compression section, thereby squeezing the exhaust gas upward. At this time, the air inlet cylinder and the exhaust port are both closed, so that the exhaust gas pressure increases, thereby improving the adsorption effect of VOCs. When the connecting column is in the adsorption section, the connecting column remains stationary, so that the high pressure state is maintained in the adsorption box to achieve continuous adsorption of VOCs. At the same time, the arc-shaped rack meshes with the driven gear to drive the connecting shaft to rotate. The connecting shaft drives the installation shaft, the installation cylinder and the third adsorption member to rotate through the active pulley, the belt and the driven pulley, thereby increasing the exhaust gas circulation speed in the compression box, so that the first adsorption member and the third adsorption member are in full contact with the exhaust gas, thereby improving the adsorption effect. At the same time, the rotating disk drives the rotating arm to rotate around the fixed axis through the contact between the arc-shaped protrusion and the abutment wheel. The rotating arm drives the ball valve core to rotate 90° through the cooperation of the linkage rod and the installation rod, so that the ball valve core opens, and the tap water is introduced into the cooling box through the vertical pipe, and then discharged from the cooling pipe, and the heat in the compression box is taken away during the discharge process to achieve cooling of the exhaust gas, thereby improving the adsorption effect. Then the connecting column enters the exhaust section, and the connecting column continues to move vertically upward. The piston plate drives the rotating plate to rotate clockwise through the contact with the inclined push plate, and the rotating plate drives the cover plate to move to the right, so that the exhaust gas in the compression box is discharged from the exhaust port, thereby completing an adsorption cycle;

[0025] 3. In the present invention, the combined VOCs adsorption cabinet is configured to illuminate the first adsorption member and the third adsorption member by turning on the light panel so that the light beads emit light. Under the illumination condition, the photocatalyst absorbs photon energy and excites electrons to transition from the valence band to the conduction band to form electron-hole pairs. These electrons and holes respectively drive the reduction and oxidation reactions of VOCs adsorbed on the surface of the photocatalyst, and finally degrade them into harmless substances such as water and carbon dioxide.

[0026] 4. In the present invention, the combined VOCs adsorption cabinet drives the sliding frame and the positioning angle plate to move horizontally by pulling the pull ring to release the fixation of the fourth adsorption member, thereby facilitating the disassembly and replacement of the fourth adsorption member. By introducing cooling water from one end of the U-shaped tube into the interior of the cabinet and draining it from the other end, the flowing cooling water takes away the heat inside the cabinet, thereby cooling the exhaust gas to improve the adsorption effect of VOCs in the exhaust gas. By pulling the pull rod downward, the card plate is driven to move downward, so that the card plate is separated from the card slot, and the fixation of the compression box is released. Then, the compression box can be moved to the left to be removed to separate it from the cabinet for easy maintenance;

[0027] 5. In the present invention, the combined VOCs adsorption cabinet achieves multiple adsorption effects on VOCs through the cabinet body and compression box. The cooperation of the rotating disk, connecting column and piston plate facilitates the pressurization, cooling and flow rate control of VOCs, thereby improving the adsorption effect of VOCs.

[0057] In this embodiment, when in use, the exhaust gas containing VOCs is introduced into the feed square tube 4 through the introduction pipe, a part of the exhaust gas is introduced into the temporary storage box 401 under the guidance of the guide inclined plate 408 for temporary storage, the VOCs in the exhaust gas are adsorbed by the second adsorbent 407, and the sealing plate 406 is pushed to move by the exhaust gas, and the other part of the exhaust gas flows to the left through the gap between the guide inclined plate 408 and the inner wall of the feed square tube 4, and is led out from the left end of the feed square tube 4, and the VOCs are further adsorbed by the fourth adsorbent 16;

[0058] By starting the driving motor 23 to drive the rotating disk 6 to rotate counterclockwise, the rotating disk 6 rotates so that the connecting column 502 enters the compression section 60101, the adsorption section 60102, the exhaust section 60103 and the suction section 60104 in sequence. The connecting column 502 moves vertically downward in the suction section 60104, and drives the piston plate 5 to move downward through the U-shaped rod 501, so that negative pressure is formed in the compression box 2, and the exhaust gas enters the compression box 2 through the air intake cylinder 9. The first adsorption member 202 and the third adsorption member 802 adsorb VOCs in the exhaust gas. The connecting column 502 moves vertically downward in the suction section 60104, and drives the piston plate 5 to move downward through the U-shaped rod 501, so that negative pressure is formed in the compression box 2, and the exhaust gas enters the compression box 2 through the air intake cylinder 9. The first adsorption member 202 and the third adsorption member 802 adsorb VOCs in the exhaust gas. When the connecting column 502 is in the adsorption section 60102, it moves vertically upward, thereby squeezing the exhaust gas upward. At this time, the air inlet cylinder 9 and the exhaust port are closed, so that the exhaust gas pressure increases, thereby improving the adsorption effect of VOCs. When the connecting column 502 is in the adsorption section 60102, the connecting column 502 remains stationary, so that the adsorption box maintains a high pressure state to achieve continuous adsorption of VOCs. At the same time, the arc-shaped rack 703 is engaged with the driven gear 702 to drive the connecting shaft 701 to rotate. The connecting shaft 701 drives the installation shaft 8 and the installation cylinder 801 through the driving pulley 804, the belt 805 and the driven pulley 803. The first adsorbent 202 and the third adsorbent 802 rotate, thereby increasing the exhaust gas circulation speed in the compression box 2, making the VOCs more evenly distributed in the gas phase or liquid phase, avoiding the occurrence of local concentrations that are too high or too low, so that the first adsorbent 202 and the third adsorbent 802 are fully in contact with the exhaust gas, thereby improving the adsorption effect. At the same time, the rotating disk 6 drives the rotating arm 1006 to rotate around the fixed axis 1007 through the contact between the arc-shaped protrusion 602 and the abutment wheel 1009, and the rotating arm 1006 drives the ball valve core 1003 to rotate 90° through the cooperation of the linkage rod 1005 and the installation rod 1004, thereby The ball valve core 1003 is opened, and tap water is introduced into the cooling box 10 through the vertical pipe 1002, and then discharged from the cooling pipe 1001. During the discharge process, the heat in the compression box 2 is taken away to cool the exhaust gas, thereby improving the adsorption effect. Then the connecting column 502 enters the exhaust section 60103, and the connecting column 502 continues to move vertically upward. The piston plate 5 drives the rotating plate 2405 to rotate clockwise through the contact with the inclined push plate 2404, and the rotating plate 2405 drives the cover plate 24 to move to the right, so that the exhaust gas in the compression box 2 is discharged from the exhaust port, thereby completing an adsorption cycle;

[0059] By turning on the light board 3 so that the lamp bead 301 emits bright light and irradiates the first adsorbent 202 and the third adsorbent 802, under the light condition, the photocatalyst absorbs the photon energy and excites the electrons to jump from the valence band to the conduction band to form electron-hole pairs. These electrons and holes drive the reduction and oxidation reactions of the VOCs adsorbed on the surface of the photocatalyst, and finally degrade them into harmless substances such as water and carbon dioxide.

[0060] The sealing plate moves up and down as the exhaust gas pressure in the inlet pipe changes, and drives the transmission rack to move synchronously. The transmission rack drives the rotating shaft and the paddle to rotate through the meshing with the transmission gear, thereby further stirring the exhaust gas to improve the distribution uniformity of VOCs and facilitate adsorption;

[0061] By pulling the pull ring 22, the sliding frame 20 and the positioning angle plate 18 are driven to move horizontally, and the fixation of the fourth adsorbent 16 is released, so as to facilitate the disassembly and replacement of the fourth adsorbent 16. By introducing cooling water from one end of the U-shaped tube 15 into the interior of the cabinet 1 and out of the other end, the flowing cooling water takes away the heat inside the cabinet 1, so as to cool the exhaust gas and improve the adsorption effect of VOCs in the exhaust gas.
