Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an energy-saving and environmentally friendly thermal oxidation furnace (RTO) device. Background Technology

[0002] Regenerative Thermal Oxidizers (RTOs) are highly efficient devices for treating low- to medium-concentration organic waste gases. Their core principle is heat storage and oxidation reaction. Using heat storage materials such as ceramics, the organic waste gas is preheated to over 800℃. The waste gas is then fully oxidized and decomposed into harmless substances in the combustion chamber, achieving a thermal efficiency exceeding 95% and an organic waste gas removal rate of over 99%. Taking a three-bed RTO as an example, the waste gas circulates between the regenerator chambers via a switching valve, achieving heat recovery. It offers significant advantages, including high efficiency, energy saving, and adaptability to various complex operating conditions. It is widely used in numerous industries such as coating, printing, and chemicals, helping companies meet environmental emission requirements and effectively reduce emissions of pollutants such as VOCs.

[0003] Currently, thermal oxidizers lack re-treatment of flue gas after combustion. The flue gas usually contains impurities such as particulate matter. If it enters the RTO directly without treatment, these particles will gradually accumulate in the pores of the heat storage medium, causing blockage and affecting its heat storage and heat transfer effects. The deterioration of the heat storage medium's performance will increase the RTO's energy consumption, reduce its processing efficiency, and may even cause the equipment to malfunction. Utility Model Content

[0006] Furthermore, a first connecting plate is connected inside the housing, one end of the first connecting plate is connected to a slide rail, one end of the slide rail is slidably connected to a slider, and one end of the slider is fixedly connected to a second connecting plate.

[0007] Furthermore, a filter box is connected to one end of the second connecting plate, and a filter plate is provided at the bottom of the filter box.

[0008] Furthermore, a drain box is provided at the bottom of the filter box, and a drain pipe is provided at the bottom of the drain box.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figures 1-4 An energy-saving and environmentally friendly thermal oxidizer (RTO) device includes: a shell 3, a transparent window 5 at one end of the shell 3, a water pipe 8 connected through one end of the shell 3, a nozzle 23 connected to the bottom of the water pipe 8, a support plate 9 connected through the middle of the nozzle 23, two sets of opposing inclined plates 10 connected inside the shell 3, a drain trough 11 opened at the top of the inclined plates 10, a sludge collection trough 12 connected to one end of the inclined plates 10, a drain pipe 20 connected to the bottom of the sludge collection trough 12, a spiral guide groove 21 opened inside the drain pipe 20, a water storage tank 2 connected to one end of the water pipe 8, a water pump 1 connected to the other end of the water pipe 8, and a flue pipe 4 connected to one side of the shell 3.

[0024] In a further embodiment of this utility model, when exhaust gas enters the equipment through the exhaust pipe 4, the water pump 1 is started. The water pump 1, as a power source, provides power for the circulation of water, causing the water in the water storage tank 2 to be transported to the nozzle 23 and other parts through the water pipe 8. The nozzle 23 sprays water onto the exhaust gas, allowing the water to fully contact the exhaust gas. During this process, particulate matter and some gaseous pollutants in the exhaust gas are captured or reacted by the water mist. They flow with the water flow towards the collection tank 12 under the action of the inclined plate 10 and the drain trough 11 opened on its surface. The water flowing into the collection tank 12 flows to the filter box 15 through the drain pipe 20. The spiral guide groove 21 opened on the surface of the drain pipe 20 causes the fluid to flow in a spiral path, accelerating the discharge rate. The support plate 9 provides support for the water pipe 8. The transparent window 5 set at one end of the housing 3 allows the operator to directly observe the exhaust gas treatment process inside the equipment without opening the equipment, such as the distribution of water flow and the operating status of components, so as to facilitate timely detection and handling of abnormalities.

[0025] Furthermore, the interior of the housing 3 is connected to a first connecting plate 13, one end of which is connected to a slide rail 14, one end of which is slidably connected to a slider 19, one end of which is fixedly connected to a second connecting plate 18, one end of which is connected to a filter box 15, a filter plate 16 is provided at the bottom of the filter box 15, a drain box 17 is provided at the bottom of the filter box 15, a drain pipe 22 is provided at the bottom of the drain box 17, and a housing door 6 is connected to one side of the housing 3, one end of which is connected to a door handle 7.

[0026] In a further embodiment of this utility model, water flowing from the drain pipe 20 to the filter box 15 is filtered by the activated carbon filled inside the filter box 15. The water or mixed fluid containing pollutants is filtered to remove solid particles, impurities, etc., purifying the fluid. Then, it is filtered again by the filter plate 16 set at the bottom of the filter box 15, and then flows into the drain box 17. Finally, it flows out through the drain pipe 22 set at the bottom. When it is necessary to replace or clean the activated carbon inside the filter box 15, the operator holds the door handle 7 and opens the housing door 6. The slide rail 14 and the slider 19 cooperate to provide a guide track for the movement of the filter box 15, so that the filter box 15 can slide smoothly and realize the position adjustment of the filter box 15. It is convenient to pull out and insert the filter box 15 for cleaning and replacing the activated carbon. The first connecting plate 13 is fixedly connected to the housing 3, and the second connecting plate 18 is fixedly connected to the slider 19.

[0027] In this application, when exhaust gas enters the equipment through the exhaust pipe 4, the water pump 1 is started. The water pump 1 serves as a power source to provide power for the circulation of water, causing the water in the water storage tank 2 to be transported through the water pipe 8 to the nozzle 23 and other parts. The nozzle 23 sprays water onto the exhaust gas, so that the water and exhaust gas can come into full contact. During this process, particulate matter and some gaseous pollutants in the exhaust gas are captured or reacted by the water mist. They flow with the water into the collection tank 12 under the action of the inclined plate 10 and the drain trough 11 on its surface. The water flowing into the collection tank 12 flows to the filter box 15 through the drain pipe 20. The spiral guide groove 21 on the surface of the drain pipe 20 causes the fluid to flow in a spiral path, which accelerates the discharge rate. The water flowing from the drain pipe 20 to the filter box 15 is filtered by the activated carbon filled inside the filter box 15. The water or mixed fluid containing pollutants is filtered to remove solid particles, impurities and other impurities, and the fluid is purified. Then it is filtered again through the filter plate 16 set at the bottom of the filter box 15, and then flows into the drain box 17. Finally, it flows out through the drain pipe 22 set at the bottom.

[0028] The foregoing has only described certain exemplary embodiments of this utility model by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of this utility model. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of this utility model.
