Description

Technical Field

[0001] The utility model belongs to the field of centralized waste gas treatment systems, in particular to a centralized production waste gas treatment system. Background Art

[0002] The waste gas treatment system is a system specially used to treat waste gas generated in industrial production or other processes. Its main purpose is to reduce or remove pollutants in the waste gas. The waste gas treatment system uses different treatment technologies and equipment to decompose, transform, adsorb or burn harmful, odorous and other pollutants in the waste gas, ultimately achieving the purpose of reducing or eliminating waste gas pollutants. These systems are of great significance for protecting the atmospheric environment, reducing acid rain formation, and controlling the greenhouse effect.

[0003] Existing waste gas treatment systems generally collect waste gas generated during industrial production processes through gas collection hoods, ventilation ducts and other equipment, and transport it to a pretreatment device to remove large particles, dust, moisture and other impurities to prevent large particles, dust, moisture and other impurities from affecting the adsorption effect of activated carbon or even clogging the pores of activated carbon. The pretreated waste gas is then discharged into the activated carbon adsorption device. Under the action of activated carbon, harmful substances in the waste gas (such as volatile organic compounds (VOCs)) are adsorbed on the surface of the activated carbon, and the adsorbed waste gas is purified. The purified air will be discharged from the bottom of the device and discharged into the atmosphere after being pressurized by the main fan. However, the activated carbon used to treat waste gas in general waste gas treatment systems needs to be replaced regularly. When replacing the activated carbon, the waste gas treatment system needs to be shut down, which reduces the efficiency of the waste gas treatment system in treating waste gas. For this reason, we have designed a centralized production waste gas treatment system to solve the above problems. Utility Model Content

[0023] In this embodiment, after the exhaust gas used in production enters the interior of the shell 1 through the air inlet pipe 2, it enters the honeycomb activated carbon 6 along the unsealed channel opening. Under the action of the honeycomb activated carbon 6, the harmful substances in the exhaust gas are adsorbed on the honeycomb activated carbon 6, thereby purifying the exhaust gas. When this set of honeycomb activated carbon 6 absorbs enough exhaust gas, the staff needs to replace the used honeycomb activated carbon 6. At this time, the drive motor 702 is started, and the output end of the drive motor 702 drives the one-way threaded screw 703 to rotate, thereby driving the drive block 704 to move along the direction of the limit column 705, thereby driving the prism 706 to move, so that the prism 706 will block the channel opening on the side of the honeycomb activated carbon 6 that needs to be replaced, and open another channel, so that the exhaust gas can enter the honeycomb activated carbon 6 along another set of filter meshes 9 for exhaust gas treatment. In this way, the exhaust gas will not stop working during the replacement of the honeycomb activated carbon 6 during the filtration process, thereby improving the purification efficiency of the exhaust gas, allowing the device to purify the exhaust gas uninterruptedly, thereby improving the overall practicality of the device.

[0024] Please refer to Figure 2-Figure 5The locking mechanism 8 includes a first limiting groove 806 provided on the inner side of the protection box 5, a sliding block 807 is slidably connected to the inner side of the first limiting groove 806, one end of the sliding block 807 is fixedly connected to a first tension spring 808, and one end of the first tension spring 808 is installed on the inner side of the first limiting groove 806, the bottom of the sliding block 807 is fixedly connected to a locking block 809, and one end of the locking block 809 passes through the bottom of the protection box 5, and a second limiting groove 810 with a width matching that of the locking block 809 is provided on the inner side of the limiting plate 4; the locking mechanism 8 also includes a second limiting groove 810 slidably connected to the second limiting groove 810 0, one end of the driving plate 811 is fixedly connected to the second tension spring 812, and one end of the second tension spring 812 is installed on the inner side of the second limiting groove 810, one side of the driving plate 811 is fixedly connected to the connecting block 804, and the inner side of the connecting block 804 is rotatably connected to the roller 803; one end of the driving plate 811 is provided with a second inclined surface 813, and both sides of the prism 706 are provided with first inclined surfaces 805, and the bottom of the locking block 809 is provided with an arc surface; one end of the protective box 5 is fixedly connected to the rectangular plate 801, and one end of the rectangular plate 801 is fixedly connected to the handle 802.

[0025] In this embodiment: after the honeycomb activated carbon 6 has absorbed enough exhaust gas, the staff needs to replace it. When the staff has replaced the honeycomb activated carbon 6 and pushed the protective box 5 into the locked position, the locking block 809 is aligned with the second limiting groove 810. At this time, under the action of the first tension spring 808, the locking block 809 is pushed downward along the outer wall of the first limiting groove 806, so that the locking block 809 moves to the inside of the second limiting groove 810, thereby fixing the position of the limiting plate 4 and improving the stability of the protective box 5 after installation. A sealing rubber is provided on the inner side of the rectangular plate 801, so that the protective box 5 can seal the rectangular plate 801 and the outer shell 1 through the sealing rubber after installation, thereby improving the overall practicality of the device;

[0026] When the driving motor 702 drives the one-way threaded screw 703 to rotate, the prism 706 moves along the limiting column 705. When the first inclined surface 805 set on the top of the prism 706 contacts the roller 803, under the action of the first inclined surface 805, the roller 803 is pushed to move inward along the outer wall of the second limiting groove 810, thereby driving the driving plate 811 to move toward the inner side of the second limiting groove 810. When it moves to the second inclined surface 813 and contacts the locking block 809, under the action of the second inclined surface 813, the locking block 809 is pushed upward. When the driving plate 811 stops moving, the locking block 809 moves to the inner side of the protective box 5, so that the protective box 5 is no longer fixed. At this time, the staff can pull the handle 802 to take out the protective box 5 and replace the honeycomb activated carbon 6 therein, thereby realizing the automatic opening of the protective box 5, thereby improving the convenience of the device, reducing the workload of the staff, and improving the overall practicality of the device.
