Description

Technical Field

[0001] This utility model relates to the field of RTO pretreatment technology, specifically to an RTO pretreatment filter with concentration detection. Background Technology

[0002] RTO, or Regenerative Thermal Oxidizer, is a core environmental protection device in the industrial field for treating high-concentration volatile organic compounds and odorous gases. It achieves the harmless treatment of organic waste gas and efficient energy utilization through the principle of high-temperature oxidation decomposition and heat recovery. It is widely used in industries that generate organic waste gas, such as chemical, spraying, printing, pharmaceutical, and coating industries. Before industrial organic waste gas enters the main RTO unit, it specifically removes dust, particulate matter, sticky substances, and trace corrosive impurities from the waste gas, preventing these impurities from damaging the RTO system, affecting treatment efficiency, or causing safety hazards. It is a key supporting component for ensuring the long-term stable and efficient operation of the RTO. However, existing RTO pretreatment filters cannot detect the discharged gas during use, making it inconvenient to filter the gas again, thus causing inconvenience in use. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an RTO pretreatment filter with concentration detection, including a main body 10, a filter screen 20, a filter layer 30, an air inlet pipe 40, a valve 1 401, an air outlet pipe 402, a valve 2 403, a collection box 50, a block block 501, an air pump 1 60, a pipe 1 601, a pipe 2 602, a gas detector 603, an air pump 2 70, an air pipe 701, an air jet 702, a moving block 703, a gasket 704, a push rod 705, a sealing plate 706, and an electric telescopic rod 707; This RTO pretreatment filter facilitates concentration detection. The specific implementation method is as follows: The main body 10 has an embedded filter screen 20 and a filter layer 30. An air inlet pipe 40 and an air outlet pipe 402 are installed on both sides of the main body 10. A valve 401 is embedded inside the air inlet pipe 40, and a valve 403 is embedded inside the air outlet pipe 402. A collection box 50 is installed at the bottom of the main body 10, and a block 501 is embedded on one side of the collection box 50. An air pump 60 is installed on the surface of the main body 10, and pipes 601 and 602 are installed on the surface of the air pump 60. A gas detector 603 is embedded on the surface of the air outlet pipe 402. A cleaning mechanism is installed inside the main body 10, including: air pumps 70 symmetrically installed on the surface of the main body 10, with air pipes 701 connected to the surface of the air pumps 700 and air nozzles 702 connected to the end of the air pipes 701; and an electric telescopic rod 707 installed on the surface of the main body 10, with a moving block 7 connected to the bottom of the electric telescopic rod 707. 03, and gaskets 704 are installed on both sides of the moving block 703. Push rods 705 are symmetrically installed at the bottom of the gaskets 704, and the end of the push rods 705 is connected to a sealing plate 706. The bottom of the main body 10 is provided with an opening, and the opening of the main body 10 is respectively set to correspond to the position of the filter screen 20 and the filter layer 30. The opening of the main body 10 is also set to correspond to the position of the collection box 50. The filter screen 20 is located on the side near the air inlet pipe 40, the filter layer 30 is located on the side near the air outlet pipe 402, the gas detector 603 is located on the side near the main body 10, the end of the first pipe 601 is connected to the air outlet pipe 402, and the first pipe 601 is installed between the gas detector 603 and the second valve 403. The jet nozzle 702 is embedded in the inside of the moving block 703, and the moving block 703 is embedded in the inside of the main body 10. The moving block 703 and the main body 10 are slidably connected. The end of the jet nozzle 702 is set to correspond to the position of the filter screen 20 or the filter layer 30.

[0022] Valve 401 inside the air inlet duct 40 opens, allowing exhaust gas to enter the main body 10 along the air inlet duct 40. The exhaust gas first passes through the surface of the filter screen 20, where the filter screen 20 intercepts dust, particulate matter, and other impurities in the exhaust gas. The gas then flows to the filter layer 30, which is an activated carbon layer. The filter layer 30 further adsorbs sticky substances and trace amounts of corrosive impurities. After filtration, the gas passes through the main body 10 and enters the collection box 50. At this time, the gas detector 603 detects the gas concentration. When the detection result meets the standard, valve 403 is opened through the control system. When the gas is turned on, the qualified gas is discharged along the air outlet pipe 402. When the gas detector 603 detects that the concentration of the treated gas does not meet the standard, the control system closes valve 2 403 and turns on air pump 1 60. Air pump 1 60 draws the unqualified gas in the air outlet pipe 402 into air pump 1 60 through the connected pipe 1 601, and then sends the unqualified gas back into the main body 10 through pipe 2 602, so that the gas is filtered again through filter screen 20 and filter layer 30 until the gas concentration meets the standard. Then valve 2 403 is turned on to discharge the gas. Simultaneously, when the gas detector 603 detects that the gas concentration is below the standard, it indicates poor filtration of the device, suggesting that the surfaces of the filter screen 20 and filter layer 30 are clogged. At this time, the gas detector 603 can activate the air pump 70 and the electric telescopic rod 707 through the control system. This causes the electric telescopic rod 707 to move the moving block 703 up and down inside the main body 10. The sliding of the moving block 703 causes the air jet 702 embedded inside it to move downwards synchronously, moving the air jet 702 to one side of the filter screen 20 and filter layer 30. At this time, the moving block 703 causes the top sealing plate 706 to move downwards, so that the bottom of the sealing plate 706 is in contact with the surface of the main body 10. At the same time, the downward movement of the moving block 703 causes the push rod 705 to move the sealing plate 706 downwards, causing the sealing plate 706 to move out of the bottom opening of the main body 10. Figure 5 At this time, the high-pressure gas generated by the second air pump 70 is transported along the air pipe 701 to the jet nozzle 702 at the end. The jet nozzle 702 sprays high-pressure gas at the surface of the filter screen 20 or the filter layer 30, blowing off the impurities attached to the surface of the filter screen 20 and the filter layer 30, so that the impurities fall into the collection box 50 through the opening at the bottom of the main body 10.

[0023] Working principle: When using this RTO pretreatment filter with concentration detection, a collection box 50, a plug 501, an air pump 60, a pipeline 601, a pipeline 602, and a gas detector 603 are set up to facilitate concentration detection and increase the overall practicality.
