Description

Technical Field

[0001] This utility model relates to the field of waste gas regenerative thermal oxidation treatment technology, and in particular to a recovery chamber with an elbow structure that improves purification efficiency. Background Technology

[0002] Currently, the innovative three-tower RTO (Regenerative Thermal Oxidizer) is a highly efficient and environmentally friendly device specifically designed for treating volatile organic compounds (VOCs). This equipment achieves regenerative combustion of waste gas through a dual-tower structure and utilizes a third tower for waste gas recovery, thereby significantly improving VOCs purification efficiency. However, the third tower of the novel RTO still faces several challenges:

[0003] The efficiency of waste gas recovery is not satisfactory: Waste gas recovery mainly relies on the characteristic that the density of waste gas is greater than that of air. By removing air from the third tower, leaked waste gas is stored and re-burned. However, the waste gas storage capacity of the third tower in the current design needs to be further improved.

[0004] The efficiency of waste gas treatment urgently needs to be improved: Due to the insufficient waste gas storage capacity of the third tower, the time and space required for the process of mixing and re-combusting the recovered waste gas with fresh waste gas have increased significantly. This will extend the processing time while maintaining the same treatment efficiency.

[0005] The cost of exhaust gas treatment needs to be further reduced: the transportation cost of the fan, the amount of gas input, the reuse of thermal storage ceramics, and the output efficiency of heat recovery are all affected by the amount of exhaust gas collected by the third tower.

[0006] To address these issues, we developed a recycling chamber with an elbow structure to improve purification efficiency. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art by providing a recovery chamber with an elbow structure that improves purification efficiency, and has the advantages of improving emission efficiency, controlling emission speed, and preventing improper emission.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a recovery chamber with a bent structure to improve purification efficiency, including an exhaust chamber and a bent head fixedly connected to the inner wall of the exhaust chamber. One end of the bent head extends out of the top of the exhaust chamber. One end of the exhaust chamber is fixedly connected to a heat insulation wall, and the bottom end is sequentially connected to a heat storage chamber, a connecting chamber and an air inlet chamber. A valve is provided at the bottom of the air inlet chamber.

[0009] Preferably, a support foot is fixedly connected to the bottom end of the heat insulation wall in the connecting cavity, and the exhaust cavity is provided with a concave cavity, which is fixedly connected to the heat insulation wall by a reinforcing plate.

[0010] Preferably, the elbow is provided with an air inlet end and an air outlet end, and a through hole is provided at the top of the exhaust chamber, and the through hole is sealed to the exhaust end end.

[0011] Preferably, a pad is provided at the bottom end of the elbow, and an L-shaped support plate is provided on the inner wall of the cavity. The support plate has airflow holes and its top end is fixedly connected to the pad.

[0012] Preferably, a U-shaped plate is provided on the inner wall of the heat storage chamber, and a heat storage layer is fixedly connected to the inner wall of the U-shaped plate. The heat storage layer is provided with guide holes.

[0013] Preferably, a first flange is provided at the bottom end of the exhaust chamber, and the first flange is fixedly connected to the outer wall of the exhaust chamber and the outer wall of the heat storage chamber by a first angle steel.

[0014] Preferably, a second flange is provided at the bottom end of the heat storage chamber, and the second flange is fixedly connected to the outer wall of the heat storage chamber and the outer wall of the connecting chamber by a second angle steel.

[0015] Preferably, an air inlet is provided at the bottom of the air intake chamber, and the air inlet is connected to the combustion chamber valve body through a pipe.

[0016] Preferably, the exhaust end is provided with an interface, which is fixedly connected to the chimney via a connecting pipe.

[0017] Preferably, the exhaust chamber is provided with a plurality of lifting lugs at the top end, and the lifting lugs are located at one end close to the exhaust chamber.

[0018] Preferably, a first square tube is provided at the bottom of the connecting cavity, the lower end of the first square tube is fixedly connected to the air inlet cavity, the bottom end of the heat insulation wall is fixedly connected to a second square tube, and the bottom ends of the first square tube and the second square tube are respectively fixedly connected to the support foot.

[0019] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0020] 1. Improve air emission efficiency. By using physical measures such as valves and heat storage layers, the backflow of exhaust gas in the recovery chamber of the three towers is prevented, thereby improving the efficiency of air emission.

[0021] 2. Control the speed of air emissions. Vertical emission methods have limited effect on improving air quality and are unlikely to significantly improve the physical properties of exhaust gases. By adding bends and adjusting the direction of the exhaust outlets, the gas flow rate can be effectively controlled, while reducing the interference of indoor and outdoor environmental factors on the emission process.

[0022] 3. Prevent improper emission of exhaust gas. Add an elbow with the exhaust port facing upwards and maintaining a distance of 120mm from the top of the tower to ensure that the exhaust gas is contained at the bottom of the elbow, thereby preventing it from being discharged from the inlet.

One end of the exhaust chamber 20 is fixedly connected to a heat insulation wall 40, and its bottom end is sequentially connected to a heat storage chamber 30, a connecting chamber 50, and an air inlet chamber 60. A valve 62 is provided at the bottom of the air inlet chamber 60. A support foot is fixedly connected to the bottom of the connecting chamber 50 and the heat insulation wall 40. The exhaust chamber 20 has a recess 22, which is fixedly connected to the heat insulation wall 40 by a reinforcing plate 42. The elbow 10 has an air inlet end 11 and an exhaust end 12. The exhaust end 12 has an interface 121, which is fixedly connected to a chimney through a connecting pipe with a valve. A through hole 21 is provided at the top of the exhaust chamber 20, and the through hole 21 is sealed to the exhaust end 12. A pad 13 is provided at the bottom of the elbow 10 to protect the outer wall of the elbow. An L-shaped support plate 14 is provided on the inner wall of the cavity 22. The support plate 14 has a bent end 142, which is fixedly connected to the inner wall of the cavity 22. An L-shaped plate 23 is provided on the outer wall of the cavity 22. The support plate 14 has an airflow hole 141, and its top end is fixedly connected to the pad 13. The air inlet 11 is 120mm away from the top of the exhaust cavity 20, and the airflow hole 141 facilitates the flow of exhaust gas. The support plate 14 provides support while also facilitating the flow of exhaust gas.

[0028] A first flange 24 is provided at the bottom end of the exhaust chamber 20. The first flange 24 is fixedly connected to the outer wall of the exhaust chamber 20 and the outer wall of the heat storage chamber 30 by first angle steel 26. Multiple lifting lugs 29 are provided at the top end of the exhaust chamber 20, with the lugs 29 positioned near the end of the exhaust chamber 20 to facilitate lifting operations. The exhaust chamber 20 and the heat storage chamber 30, as well as the heat storage chamber 30 and the connecting chamber 50, are fixedly connected by flanges and angle steel, facilitating transportation and installation.

[0029] A U-shaped plate 31 is provided on the inner wall of the heat storage chamber 30. A heat storage layer 32 is fixedly connected to the inner wall of the U-shaped plate 31. The heat storage layer 32 is provided with guide holes 321. A support frame 33 is provided at the bottom end of the heat storage layer 32. A second flange 35 is provided at the bottom end of the heat storage chamber 30. The second flange 35 is fixedly connected to the outer wall of the heat storage chamber 30 and the outer wall of the connecting cavity 50 by a second angle steel 51. The heat storage layer 32 stores the heat of the waste gas and guides the waste gas to the elbow 10.

[0030] A first square tube 52 is provided at the bottom of the connecting cavity 50. The lower end of the first square tube 52 is fixedly connected to the air inlet cavity 60.

[0031] An air inlet 61 is provided at the bottom of the air inlet chamber 60, and the air inlet 61 is connected to the combustion chamber valve body through a pipe. The exhaust gas after combustion in the combustion chamber enters the recovery chamber through the air inlet. The valve 62 of the air inlet 61 prevents the exhaust gas after combustion from flowing back.

[0032] In the recovery chamber, incompletely discharged exhaust gas and exhaust gas generated during valve switching are guided to the recovery chamber of the third tower for storage. Given that exhaust gas is denser than air, it tends to accumulate at the bottom of the recovery chamber. To ensure effective air discharge from the top of the recovery chamber, an elbow structure not only improves net air emission efficiency but also controls the air emission rate and prevents improper exhaust gas discharge. The treated exhaust gas, along with fresh air, is transported to the combustion chamber for complete combustion, reducing environmental pollution.

All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
