Description

Technical Field

[0001] This utility model relates to the field of air preheater technology, and more specifically, to an air preheater for municipal solid waste incineration. Background Technology

[0002] In municipal solid waste incineration projects, due to the low calorific value of waste, it is usually necessary to heat the combustion air to ensure stable combustion. Therefore, an air preheater is required. Existing air preheaters typically use the hot exhaust gas from the incinerator to preheat the combustion air, which has the advantages of improving the boiler's heat exchange performance and reducing energy consumption. However, the temperature of the hot exhaust gas is greatly affected by the ambient temperature, which means that the air preheater is not enough to preheat the combustion air to the specified standard, thereby reducing the incinerator's efficiency in incinerating waste. To solve the above problems, we have introduced the following device. Utility Model Content

[0029] By adopting the above technical solution, this municipal solid waste incineration air preheater, through the installation of a delivery pump 7, a serpentine tube 12, a heating plate 13, and a temperature sensor 14, allows the combustion air to be preheated to a specified standard. The controller 17 then controls the delivery pump 7, heating plate 13, and temperature sensor 14 to enter the working state. The combustion air discharged from the outlet 2 of the main body 1 sequentially passes through the gas collection hood 4, the first conduit 5, the delivery pump 7, the second conduit 8, and the serpentine tube 12 into the inspection chamber 11, and is then output through the exhaust pipe 16. The temperature sensor 14 in the inspection chamber 11 continuously monitors the combustion air discharged from the serpentine tube 12 and transmits the signal to the controller 17. This allows the controller 17 to automatically adjust the heating efficiency of the heating plate 13, ensuring that the heating plate 13 heats the combustion air passing through the serpentine tube 12 to a specific temperature, facilitating the preheating of the combustion air to the specified standard.

[0030] Specifically, a guide rail 19 is fixedly connected to the surface of the main body 1, and a slider 20 is slidably connected inside the guide rail 19. A cover plate 21 is provided on the side of the inspection port 18. The slider 20 is fixedly connected to the surface of the cover plate 21. A threaded tube 22 passes through the surface of the cover plate 21. A forward and reverse motor 23 is fixedly connected to the surface of the main body 1 through a mounting base.

A rotating shaft 25 is fixedly connected to the surface of the support plate 24 through a bearing. The other end of the output shaft of the forward and reverse motor 23 is fixedly connected to one end of the rotating shaft 25. A threaded post 26 is fixedly connected to the other end of the rotating shaft 25. The threaded post 26 is threadedly connected to the threaded tube 22.

[0031] By adopting the above technical solution, the municipal solid waste incineration air preheater, through the setting of a forward and reverse motor 23, a threaded column 26, and a threaded tube 22, allows for maintenance of the interior of the main body 1. With the cover plate 21 sealing the inspection port 18, the controller 17 controls the operation of the forward and reverse motor 23, thereby driving the rotating shaft 25 and the threaded column 26 to rotate. With the cooperation of the threaded column 26 and the threaded tube 22, the threaded tube 22, the cover plate 21, and the slider 20 move along the guide rail 19, so that the cover plate 21 moves away from the inspection port 18, making it convenient for people to carry out maintenance of the interior of the main body 1 through the inspection port 18.

[0032] Specifically, the controller 17 is electrically connected to the power plug 27 via a wire.

[0033] Specifically, a sealing gasket 28 is fixedly connected to the surface of the cover plate 21.

[0034] Specifically, there are two sets of guide rails 19 and sliders 20, which are symmetrically arranged on the side of the cover plate 21.

[0035] Specifically, there are two sets of heating plates 13, which are symmetrically arranged on the side of the serpentine tube 12.

[0036] Specifically, the bottom of the base plate 3 is fixedly connected with four sets of feet 29, which are arranged in a rectangular pattern at the bottom of the base plate 3.

[0037] The working principle of this utility model is as follows: In use, the power plug 27 is first connected to an external circuit. Then, the exhaust gas pipe of the incinerator is connected to the air inlet of the main body 1, and the end of the exhaust pipe 16 is connected to the air inlet of the incinerator, thus installing the device on the incinerator. Then, the controller 17 controls the delivery pump 7, heating plate 13, and temperature sensor 14 to enter the working state. The combustion air discharged from the outlet 2 of the main body 1 sequentially passes through the gas collection hood 4, the first conduit 5, the delivery pump 7, the second conduit 8, and the serpentine pipe 12 into the inspection chamber 11, and is then output through the exhaust pipe 16. The temperature sensor 14 in the inspection chamber 11 monitors the combustion air discharged from the serpentine pipe 12. The system continues to monitor and transmits signals to the controller 17, which automatically adjusts the heating efficiency of the heating plate 13. This allows the heating plate 13 to heat the combustion air passing through the serpentine tube 12 to a specific temperature, thus preheating the combustion air to a specified standard. When the interior of the main body 1 needs to be inspected, with the cover plate 21 sealing the inspection port 18, the controller 17 controls the forward and reverse motors 23 to operate, thereby driving the rotating shaft 25 and the threaded column 26 to rotate. With the cooperation of the threaded column 26 and the threaded tube 22, the threaded tube 22, the cover plate 21, and the slider 20 move along the guide rail 19, causing the cover plate 21 to move away from the inspection port 18, so that people can inspect the interior of the main body 1 through the inspection port 18.
