[0002] RTO, also known as regenerative thermal incinerator, is a high-efficiency organic waste gas treatment equipment. Compared with traditional catalytic combustion and direct-fired thermal oxidation furnaces (TO), RTO has the characteristics of high thermal efficiency, low operating cost, and the ability to treat large air volume and low-concentration waste gas. It can also perform secondary waste heat recovery, greatly reducing production and operation costs.
[0003] During the use of RTO, the high-temperature gas flow generated by oxidation flows out through the ceramic heat storage body and stores heat, which can absorb the heat energy in the exhaust gas. However, it is impossible to fully absorb the heat energy, and a high amount of heat is still discharged from the exhaust pipe to the atmosphere, resulting in a high temperature at the exhaust pipe and a waste of waste heat. At the same time, when the RTO is performing a cleaning procedure, the outside air will be drawn into the RTO. At the same time, the exhaust gas will also contain a certain amount of dust and other substances. When discharged through the exhaust pipe, it will cause dust accumulation in the exhaust pipe.

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] The utility model provides a technical solution: Figures 1 to 5 As shown, in the present embodiment, an RTO organic waste gas treatment equipment with high waste heat utilization efficiency comprises an outlet pipe 1 and an exhaust chimney 2, one end of the outlet pipe 1 is mounted on the outlet hole of the RTO organic waste gas treatment equipment, the other end of the outlet pipe 1 is mounted on the bottom of the exhaust chimney 2, and is connected to the exhaust chimney 2, a fixing plate 3 is fixedly mounted inside the bottom end of the exhaust chimney 2, an exhaust pipe 4 is fixedly mounted on the top of the fixing plate 3 in a ring array with the central axis of the fixing plate 3 as the axis, the exhaust pipe 4 is connected to the bottom end of the exhaust chimney 2, a hot water absorption pipe 5 is wound around the outside of the exhaust pipe 4, water is passed through the inside of the hot water absorption pipe 5, a filter screen 6 for filtering the gas discharged from the RTO organic waste gas treatment equipment is fixedly mounted below the fixing plate 3, and a cleaning plate 7 for pushing and cleaning the surface of the filter screen 6 is installed below the filter screen 6.
[0022] like Figures 1 to 5As shown, a water tank 8 is placed beside the exhaust chimney 2, and a water inlet pipe 9 is fixedly installed at the bottom end of the water tank 8. The end of the water inlet pipe 9 away from the water tank 8 is installed at the top of the exhaust chimney 2, and is circular and fixed at the top of the exhaust chimney 2. The top ends of several hot water absorption pipes 5 are connected to the water inlet pipe 9, and a first water pump 10 is fixedly installed in the middle of the water inlet pipe 9. A water outlet pipe 11 is fixedly installed between the bottom ends of the several hot water absorption pipes 5, and the water outlet pipe 11 is arranged in the middle of the exhaust chimney 2, and a second water pump 12 is fixedly installed at the end of the water outlet pipe 11 away from the hot water absorption pipe 5.
[0023] Through the operation of the first water pump 10, the water in the water tank 8 enters the hot water absorption pipe 5 from the water inlet pipe 9, and the hot water absorption pipe 5 absorbs the heat in the exhaust pipe 4. Then, through the operation of the second water pump 12, the water is pumped out from the water outlet pipe 11. The heated water can be used in factories or workers' dormitories, etc., thereby improving the utilization efficiency of waste heat.
[0024] like Figures 1 to 5 As shown, the hot water absorption pipe 5 is arranged in a rectangular shape and is completely wrapped around the outer side of the exhaust pipe 4.
[0025] By increasing the contact area between the heat absorbing pipe 5 and the exhaust pipe 4 , the heat in the gas discharged from the exhaust pipe 4 can be absorbed as much as possible.
[0026] like Figures 1 to 5 As shown, a fixing column 13 is fixedly installed in the middle of the fixing plate 3, and the fixing column 13 is arranged to pass through the filter screen 6. The outer side of the bottom end of the fixing column 13 is rotatably connected to the cleaning plate 7, and the upper surface of the cleaning plate 7 is contacted with the lower surface of the filter screen 6. An eccentric column 14 is fixedly installed in the middle of the cleaning plate 7, and a push-pull plate 15 is rotatably installed on the outer side of the eccentric column 14. A through hole 16 for the push-pull plate 15 to pass through is opened on the exhaust pipe 2.
[0027] After the filter screen 6 has filtered the gas for a long time, the block 17 can be slid out of the perforation 16, and the push-pull plate 15 can be rotated and pulled back and forth. Since the push-pull plate 15 is rotatably installed on the outside of the eccentric column 14 installed in the middle of the cleaning plate 7, the cleaning plate 7 will be driven to reciprocate under the filter screen 6, and the dust accumulated on the surface of the filter screen 6 can be scraped off.

[0029] When the push-pull plate 15 is reciprocated and pulled, the gripping range of the push-pull plate 15 is relatively large, and the through hole 16 can be blocked by the blocking block 17 to prevent the heat in the exhaust gas from being dissipated.
[0030] like Figures 1 to 5As shown, a sealing baffle 18 is rotatably mounted on the bottom end of the exhaust pipe 2 through a hinge.
[0031] The bottom end of the exhaust pipe 2 can be opened by rotating the sealing baffle 18 to clean the accumulated dust.
[0032] The utility model provides an RTO organic waste gas treatment device with high waste heat utilization efficiency. The specific working principle is as follows:
[0033] When the device is in use, when the gas in the RTO organic waste gas treatment equipment is discharged through the outlet pipe 1, the gas will first enter the bottom of the exhaust pipe 2, filter the gas through the filter 6, and then enter the exhaust pipe 4. At the same time, the water in the water tank 8 enters the hot water absorption pipe 5 from the water inlet pipe 9 through the operation of the first water pump 10. The hot water absorption pipe 5 will absorb the heat in the exhaust pipe 4, and then the water will be pumped out from the outlet pipe 11 through the operation of the second water pump 12. The heated water can be used in the factory or workers' dormitory. etc., thereby improving the utilization efficiency of waste heat. After the filter screen 6 has filtered the gas for a long time, the block 17 can be slid out of the perforation 16, and the push-pull plate 15 can be rotated and pulled back and forth. Since the push-pull plate 15 is rotatably installed on the outer side of the eccentric column 14 installed in the middle of the cleaning plate 7, the cleaning plate 7 will be driven to rotate back and forth under the filter screen 6, and the dust accumulated on the surface of the filter screen 6 can be scraped off and dropped to the bottom of the exhaust pipe 2. People can rotate the sealing baffle 18 to clean the dust accumulated at the bottom of the exhaust pipe 2.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
