Description

Technical Field

[0001] This utility model relates to the field of incineration power generation technology, specifically a heat recovery and efficiency enhancement device for municipal solid waste incineration power generation. Background Technology

[0002] Currently, in the field of municipal solid waste treatment, incineration power generation technology has become an important treatment method. Traditional municipal solid waste incineration power generation devices generate electricity by burning municipal solid waste, but at the same time, they produce a large amount of high-temperature exhaust gas. This exhaust gas not only contains combustible components, but also contains harmful substances. If it is directly emitted into the atmosphere, it will cause serious pollution to the environment.

[0003] While some municipal solid waste incineration power plants have attempted to purify the generated waste gas, there are still shortcomings in the recovery and utilization of waste gas heat. Typically, the temperature of the waste gas just discharged is still very high, reaching 200°C to 600°C. If this heat is not effectively utilized, it will result in energy waste. In addition, existing waste gas purification equipment often requires a large amount of cooling energy when treating high-temperature waste gas, which not only increases operating costs but also reduces overall energy utilization efficiency.

[0004] Therefore, we propose a heat recovery and recycling efficiency enhancement device for municipal solid waste incineration power generation, which can recover and utilize the heat from waste gas and preheat the heating water, thereby greatly improving the efficiency of hot water conversion into steam and thus improving power generation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a heat recovery and efficiency enhancement device for municipal solid waste incineration power generation, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat recovery and circulation efficiency enhancement device for municipal solid waste incineration power generation, comprising an incineration station, an incineration chamber fixedly installed inside the incineration station, an exhaust pipe connected to one end of the side wall of the incineration chamber, a purification channel connected to the other end of the exhaust pipe, and a heat recovery and circulation mechanism installed on the incineration station and the purification channel.

[0007] The heat recovery circulation mechanism includes a spiral tube installed inside the purification channel, a return pipe connected to the top of the spiral tube, a water tank connected to the other end of the return pipe, a booster pump connected to one end of the water tank via a guide pipe, and a heating pipe connected to the outlet of the booster pump. A temperature monitoring instrument is fixedly installed on the inner side wall of the water tank.

[0008] Optionally, the spiral tubes are distributed in a spring-like manner inside the purification channel, and the heating tubes are distributed on the top side inside the incineration chamber.

[0009] Optionally, a flow chamber is fixedly installed on the top of the incineration station, and one end of the flow chamber is connected to a heating pipe.

[0010] By adopting the above technical solution, water vapor generated inside the heating tube is discharged from the flow chamber.

[0011] Optionally, the other end of the circulation chamber is connected to a water tank via a pipe, and a steam turbine is rotatably mounted on one end of the top of the circulation chamber.

[0012] By adopting the above technical solution, thermal energy can be converted into electrical energy.

[0013] Optionally, a circulation pump is fixedly installed on one side inside the water tank, and the inlet end of the circulation pump is connected to the other end of the return pipe.

[0014] By adopting the above technical solution, the circulating water inside the water tank can circulate within the return pipe.

[0015] Optionally, multiple sets of equidistantly distributed pipe clamps are fixedly installed on the side wall of the purification channel, and the multiple sets of pipe clamps are equidistantly distributed on the side wall of the spiral tube.

[0016] By adopting the above technical solution, the spiral tube can be fixed.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] The technical solution of this application involves continuously incinerating municipal solid waste in an incineration chamber. The resulting exhaust gas needs to be purified to remove harmful substances. When the exhaust gas is introduced into the purification channel, its temperature still reaches 200°C to 600°C. The spiral tube installed inside the purification channel absorbs the heat from the exhaust gas and heats the circulating water inside the spiral tube. When the circulating water is introduced into the water tank from the return pipe, it preheats the circulating water inside the tank. With the temperature monitoring instrument installed on the side wall of the water tank detecting the continuous rise in the circulating water temperature, the pressure output of the booster pump can be continuously adjusted, thereby increasing the water flow rate inside the heating tube. This ensures that the heating tube can continuously shorten the time to complete the heat exchange efficiency of the circulating water, further improving the power generation efficiency.

[0019] Multiple sets of equally spaced pipe clamps are fixedly installed on the side wall of the purification channel. When the spiral tube is installed inside the purification channel, the multiple sets of equally spaced pipe clamps are fixedly installed on the side wall of the purification channel to fix the spiral tube at different positions, so that the spiral tube can be firmly fixed inside the purification channel and the heat inside the purification channel can be absorbed.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a heat recovery and circulation efficiency enhancement device for municipal solid waste incineration power generation, including an incineration station 1, an incineration chamber 11 fixedly installed inside the incineration station 1, an exhaust pipe 2 connected to one end of the side wall of the incineration chamber 11, a purification channel 21 connected to the other end of the exhaust pipe 2, and a heat recovery and circulation mechanism installed on the incineration station 1 and the purification channel 21.

[0026] The heat recovery circulation mechanism includes a spiral tube 22 installed inside the purification channel 21, a return pipe 23 connected to the top of the spiral tube 22, a water tank 24 connected to the other end of the return pipe 23, a booster pump 32 connected to one end of the water tank 24 through a guide pipe, and a heating pipe 12 connected to the outlet of the booster pump 32. A temperature monitoring instrument 33 is fixedly installed on the inner side wall of the water tank 24. The spiral tube 22 is distributed in a spring-like manner inside the purification channel 21, and the heating pipe 12 is distributed on the top side inside the incineration chamber 11.

[0027] By continuously incinerating municipal solid waste in the incineration chamber 11, the generated exhaust gas needs to be purified to remove harmful substances. When the exhaust gas is introduced into the purification channel 21, the temperature will still reach 200℃ to 600℃. With the help of the spiral tube 22 installed inside the purification channel 21, the temperature in the exhaust gas can be absorbed and the circulating water inside the spiral tube 22 can be heated. When the circulating water is introduced into the water tank 24 from the return pipe 23, it can preheat the circulating water inside the water tank 24. With the temperature monitoring instrument 33 installed on the side wall of the water tank 24 detecting the continuous rise in the circulating water temperature, the pressure output of the booster pump 32 can be continuously changed, thereby increasing the water flow rate inside the heating tube 12. This ensures that the heating tube 12 can continuously shorten the time to complete the heat exchange efficiency of the circulating water, further improving the power generation efficiency.

[0028] In this technical solution, multiple sets of equally spaced pipe clamps 3 are fixedly installed on the side wall of the purification channel 21, and multiple sets of pipe clamps are equally spaced on the side wall of the spiral pipe 22, which can fix the spiral pipe 22.

[0029] When the spiral tube 22 is installed inside the purification channel 21, multiple sets of equidistantly distributed pipe clamps 3 are fixedly installed on the side wall of the purification channel 21. By fixing the spiral tube 22 at different positions through multiple sets of pipe clamps 3, the spiral tube 22 can be firmly fixed inside the purification channel 21 to absorb the heat inside the purification channel 21.

[0030] In this technical solution, a circulation pump 31 is fixedly installed on one side of the water tank 24. The water inlet of the circulation pump is connected to the other end of the return pipe 23, so that the circulating water inside the water tank 24 can circulate inside the return pipe 23.

[0031] As the spiral tube 22 continuously absorbs heat from the inside of the purification channel 21, it synchronously drives the circulation pump 31, which continuously delivers the circulating water inside the water tank 24 to the spiral tube 22, ensuring the circulation of the spiral tube 22, the return pipe 23, and the circulating water inside the water tank 24.

[0032] In this technical solution, a flow chamber 13 is fixedly installed on the top of the incineration station 1. One end of the flow chamber 13 is connected to the heating pipe 12, so that the water vapor generated in the heating pipe 12 is discharged from the flow chamber 13. The other end of the flow chamber 13 is connected to the water tank 24 through a pipe. A steam turbine 14 is rotatably installed on one end of the top of the flow chamber 13, which can convert thermal energy into electrical energy.

[0033] By introducing a large amount of domestic waste into the incineration chamber 11, the high-temperature flue gas generated by the incinerator is introduced into the waste heat boiler. Through the heat exchange process, the water in the boiler is heated into high-temperature and high-pressure steam. The high-temperature and high-pressure steam drives the steam turbine 14 to rotate, and the steam turbine 14 drives the generator to rotate, thereby converting heat energy into electrical energy.

[0034] In operation, a large amount of domestic waste is first introduced into the incineration chamber 11. The high-temperature flue gas generated by the incinerator is then introduced into the waste heat boiler. Through a heat exchange process, the water in the boiler is heated into high-temperature, high-pressure steam. This high-temperature, high-pressure steam drives the turbine 14 to rotate, which in turn drives the generator, thus converting heat energy into electrical energy. Simultaneously, as the incineration chamber 11 continuously incinerates domestic waste, the resulting exhaust gas needs to be purified to remove harmful substances. The purification process typically includes denitrification, deacidification, dust removal, dioxin removal, and heavy metal removal to ensure that the flue gas emissions meet environmental standards. The exhaust gas, when introduced into the purification channel 21, still reaches a temperature of 200℃ to 600℃. The spiral tube 22 installed inside the purification channel 21 absorbs the heat from the exhaust gas and heats the circulating water inside the spiral tube 22. After being introduced into the water tank 24 through the return pipe 23, the circulating water inside the water tank 24 can be preheated. With the temperature monitoring instrument 33 installed on the side wall of the water tank 24 detecting the continuous rise in the circulating water temperature, the output pressure of the booster pump 32 can be continuously changed, thereby increasing the water flow velocity inside the heating tube 12. This ensures that the heating tube 12 can continuously shorten the time to complete the heat exchange efficiency of the circulating water, further improving the power generation efficiency. At the same time, multiple sets of equally spaced pipe clamps 3 are fixedly installed on the side wall of the purification channel 21, and multiple sets of pipe clamps are equally spaced on the side wall of the spiral tube 22. When the spiral tube 22 is installed inside the purification channel 21, the multiple sets of equally spaced pipe clamps 3 are fixedly installed on the side wall of the purification channel 21. By fixing the spiral tube 22 at different positions through multiple sets of pipe clamps 3, the spiral tube 22 can be firmly fixed inside the purification channel 21, absorbing the heat inside the purification channel 21.
