Description

Technical Field

[0001] This utility model relates to the field of oxidation device technology, specifically to an energy-saving regenerative thermal oxidation device. Background Technology

[0002] Energy-saving regenerative thermal oxidizers are environmentally friendly devices specifically designed for treating industrial waste gases. Their core function is to efficiently decompose harmful gases through a regenerative oxidation process, while integrating a heat recovery system to improve energy efficiency. The device typically consists of the regenerative thermal oxidizer body and auxiliary components, such as an inlet box, outlet pipe, and inlet pipe, to guide the flow of waste gas. Key features include built-in filters to intercept large particles and prevent them from entering the oxidation zone, thus avoiding equipment blockage or damage; and an insulated frame and insulated box design, combined with heat-conducting components (such as serpentine and spiral tubes) and a liquid pump system to form a closed-loop heat exchange circuit. This device can efficiently recover and reuse excess heat generated during the oxidation process, for example, by preheating the inlet gas or providing heat for other processes, thereby significantly reducing overall energy consumption. Its advantages include improved energy efficiency, reduced operating costs, and ensured stability and reliability of the waste gas treatment process.

[0003] Although regenerative thermal oxidizers are widely used in industrial waste gas treatment, existing technologies still have significant shortcomings. First, the heat recovery mechanism is often inadequate; most devices lack efficient heat exchange designs, resulting in excess heat generated during the oxidation process not being effectively captured and reused, but instead being directly dissipated into the environment. This not only wastes energy but also increases additional cooling requirements, reducing the overall energy-saving potential of the system. Second, filtration systems are difficult to maintain. Existing filters are usually fixed inside the inlet pipe and lack convenient maintenance structures, making the removal of clogged residues or filter replacement cumbersome and time-consuming, affecting continuous equipment operation. Furthermore, insufficient filtration allows large particles to easily enter the oxidizer, causing equipment wear, reduced efficiency, or even malfunctions. These shortcomings limit the reliability, ease of maintenance, and long-term economic viability of the device. Therefore, we propose an energy-saving regenerative thermal oxidizer. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an energy-saving regenerative thermal oxidation device that facilitates the recovery of excess heat during the use of the regenerative thermal oxidation device body, while preventing large particles of residue from entering the interior of the regenerative thermal oxidation device body, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving regenerative thermal oxidation device, comprising a regenerative thermal oxidation device body and a liquid extraction assembly;

[0006] The main body of the regenerative thermal oxidation device includes: an air inlet box on the right side; an air outlet pipe fixed inside the air outlet on the left side of the air inlet box; an air outlet pipe connected to an air inlet ring on the right side of the main body of the regenerative thermal oxidation device; an air inlet pipe fixed inside the air inlet on the right side of the air inlet box; a filter screen fixed inside the air inlet pipe; a heat insulation frame fixed at the lower end of the surface of the main body of the regenerative thermal oxidation device; a heat insulation box fixed above the heat insulation frame; a heat-conducting component installed inside the heat insulation box; and maintenance and reset components installed on the circumferential surface of the air inlet pipe.

[0007] Liquid extraction assembly: includes a liquid extraction pump, an inlet pipe, an outlet pipe, and a spiral tube. The liquid extraction pump is installed on the upper side of the air inlet box. An inlet pipe is fixed inside the liquid inlet of the liquid extraction pump, and an outlet pipe is fixed inside the liquid outlet of the liquid extraction pump. A spiral tube is fixed inside the air inlet box. The right end of the outlet pipe is connected to the right end of the spiral tube. The input end of the liquid extraction pump is electrically connected to the output end of an external control switch group. The liquid extraction pump draws the heat transfer oil inside the serpentine tube into the spiral tube.

[0008] Furthermore, the heat-conducting assembly includes a heat-conducting frame, a serpentine tube, a return pipe, and a liquid guiding pipe. A uniformly distributed heat-conducting frame is fixed on the upper side of the surface of the regenerative thermal oxidation device. All heat-conducting frames are located inside the heat insulation box. Openings are provided on the sides of all heat-conducting frames. A serpentine tube is fixed inside each opening. A return pipe is fixed to the left end of the serpentine tube and is connected to the liquid inlet pipe. A liquid guiding pipe is fixed to the right end of the serpentine tube and is connected to the left end of the spiral tube. By setting a uniformly distributed heat-conducting frame, excess heat inside the regenerative thermal oxidation device is discharged.

[0009] Furthermore, the maintenance assembly includes an arc-shaped plate, a fixing plate, a connecting rod, and a locking rod. An opening is provided at the lower end of the circumferential surface of the air intake pipe, and an arc-shaped plate is disposed inside the opening. The arc-shaped plate is located at the right end of the filter screen. Two corresponding fixing plates are fixed on the circumferential surface of the air intake pipe. A connecting hole is provided in the middle of the fixing plate, and a connecting rod is slidably connected inside the connecting hole. Both connecting rods are fixed to the upper side of the arc-shaped plate. A locking hole is provided on the circumferential surface of the connecting rod, and a locking rod is engaged inside the locking hole. This maintenance assembly facilitates user maintenance and repair of the filter screen.

[0010] Furthermore, the reset assembly includes a fixed ring, a spring, and a slip ring. The fixed ring, spring, and slip ring are fitted onto the circumferential surface of the intake pipe. The spring is fixed between the fixed ring and the slip ring. The fixed ring is fixed on the circumferential surface of the intake pipe. Both locking rods are fixed to the right end of the slip ring. The reset assembly drives the slip ring to reset.

[0011] Furthermore, two corresponding handles are fixed on the circumferential surface of the slip ring, and rubber sleeves are fixed on the circumferential surface of the handles. The handles facilitate the user to pull the slip ring to move it.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This energy-saving regenerative thermal oxidation device has the following advantages:

[0013] 1. The heat-conducting frame in the heat-conducting component is closely attached to the surface of the regenerative thermal oxidation device. The serpentine tube embedded inside forms a high-efficiency heat conduction channel. In conjunction with the pump in the liquid pumping component, the heat-conducting medium is driven to circulate. This allows the spiral tube to use the recovered waste heat to continuously preheat the incoming waste gas. This active heat circulation mechanism significantly improves energy conversion efficiency and fundamentally reduces the external energy demand.

[0014] 2. The arc-shaped plate of the maintenance component and the slip ring and spring of the reset component form a linkage structure. When the operating handle slides the slip ring laterally, the locking rod automatically disengages from the locking hole of the connecting rod, causing the arc-shaped plate to move down along the air inlet pipe opening, directly exposing the filter area for easy cleaning. After releasing the handle, the spring pushes the slip ring to automatically reset and lock. This mechanical linkage design allows the maintenance of the filtration system to be completed without professional tools, greatly reducing downtime and ensuring the reliability of continuous equipment operation.

The resetting assembly 5 and the heat-conducting assembly 3 include a heat-conducting frame 31, a serpentine tube 32, a return pipe 33, and a liquid guide pipe 34. The upper surface of the regenerative thermal oxidation device body 1 is fixed with uniformly distributed heat-conducting frames 31. All heat-conducting frames 31 are located inside the insulation box 13. Openings are provided on the sides of all heat-conducting frames 31, and serpentine tubes 32 are fixed inside all openings. A return pipe 33 is fixed to the left end of the serpentine tube 32, which is connected to the liquid inlet pipe 22. A liquid guide pipe 34 is fixed to the right end of the serpentine tube 32, and the liquid guide pipe 34 is connected to the left end of the spiral tube 24. The interconnected maintenance component 4 includes an arc-shaped plate 41, a fixing plate 42, a connecting rod 43, and a locking rod 44. An opening is provided at the lower end of the circumferential surface of the intake pipe 11, and the arc-shaped plate 41 is disposed inside the opening. The arc-shaped plate 41 is located at the right end of the filter screen 12. Two corresponding fixing plates 42 are fixed on the circumferential surface of the intake pipe 11. A connecting hole is provided in the middle of the fixing plate 42, and a connecting rod 43 is slidably connected inside the connecting hole. Both connecting rods 43 are fixed to the upper side of the arc-shaped plate 41. A locking hole is provided on the circumferential surface of the connecting rod 43, and a locking rod 44 is engaged inside the locking hole. (Reset assembly) Component 5 includes a fixed ring 51, a spring 52, and a slip ring 53. The fixed ring 51, spring 52, and slip ring 53 are fitted onto the circumferential surface of the air intake pipe 11. The spring 52 is fixed between the fixed ring 51 and the slip ring 53. The fixed ring 51 is fixed on the circumferential surface of the air intake pipe 11. Both locking rods 44 are fixed to the right end of the slip ring 53. The slip ring 53 is reset by setting the reset component 5. The maintenance component 4 facilitates the user to maintain and repair the filter screen 12. The heat conduction frame 31 with uniform distribution is set to conduct excess heat from inside the body 1 of the regenerative thermal oxidation device.

[0024] Liquid extraction assembly 2 includes a liquid extraction pump 21, an inlet pipe 22, an outlet pipe 23, and a spiral tube 24. The liquid extraction pump 21 is installed on the upper side of the air inlet box 9. The inlet pipe 22 is fixed inside the liquid inlet of the liquid extraction pump 21, and the outlet pipe 23 is fixed inside the liquid outlet of the liquid extraction pump 21. The spiral tube 24 is fixed inside the air inlet box 9. The right end of the outlet pipe 23 is connected to the right end of the spiral tube 24. The input end of the liquid extraction pump 21 is electrically connected to the output end of an external control switch group.

[0025] Among them, two corresponding handles 6 are fixed on the circumferential surface of the slip ring 53, and rubber sleeves 7 are fixed on the circumferential surface of the handles 6. The handles 6 are designed to facilitate the user to pull the slip ring 53 to move.

[0026] The working principle of the energy-saving regenerative thermal oxidation device provided by this utility model is as follows: Waste gas enters the device through the inlet pipe 11, passes through the filter screen 12 to intercept large particles of residue, and then enters the inlet box 9. It is then transported through the outlet pipe 10 to the inlet ring of the regenerative thermal oxidation device body 1 for oxidation treatment. The heat generated during oxidation is absorbed by the heat-conducting frame 31 and transferred to the insulation box 13 through the heat-conducting medium in the serpentine tube 32. After the liquid pump 21 is started, the heat-conducting medium is pumped into the liquid pumping assembly 2 through the liquid inlet pipe 22, and then transported to the spiral tube 24 through the liquid outlet pipe 23. The spiral tube 24 is coiled inside the inlet box 9, using the heat of the heat-conducting medium to preheat the incoming waste gas, thus achieving heat recovery. During the circulation process, the heat transfer medium flows back from the spiral tube 24 to the serpentine tube 32 via the liquid guide tube 34, forming a closed heat exchange loop. When the filter screen 12 becomes clogged, the handle 6 is pulled to the right to move the slip ring 53, causing the locking rod 44 to disengage from the locking hole of the connecting rod 43. At this time, the connecting rod 43 can move freely, causing the arc plate 41 to move down, exposing the opening at the lower end of the air inlet pipe 11, which is convenient for cleaning residue. After maintenance, the arc plate 41 is reset, the handle 6 is released, the spring 52 pushes the slip ring 53 to the left, and the locking rod 44 re-engages into the locking hole of the connecting rod 43 to fix the structure. This process efficiently recovers the oxidation waste heat through the heat transfer component 3, and realizes the recycling of thermal energy using the liquid pumping component 2. At the same time, the maintenance component 4 and the reset component 5 ensure convenient maintenance of the filtration system, comprehensively improving energy efficiency and operational reliability.
