As shown in fig. 1 to 5, the invention provides a low-temperature magnetization degradation furnace with a power generation function, which comprises a furnace body 10, a power generation system 20 and the like. The top of the furnace body 10 is provided with a chimney 11 and a feeding port 12, the chimney 11 is made of heat-conductive material, and a plurality of magnetizers 13 are arranged at the lower part of the periphery of the furnace body 10.

Organic waste is fed into the treatment chamber from a feed port 12 of the furnace body 10 and ignited with open fire. The air enters the furnace body 10 after being magnetized by the magnetizer 13, the decomposition of the organic waste in the furnace body 10 is effectively promoted, the combustible substances in the organic waste are partially combusted, the temperature of the furnace body 10 is raised to about 300 ℃, and the generated heat enables the organic waste to generate continuous pyrolysis reaction. The pyrolysis gasification product and a small amount of fly ash are discharged into the atmosphere after being treated by a flue gas treatment unit on a chimney 11.

The power generation system 20 is disposed above the furnace body 10. Specifically, the power generation system 20 includes a water tank 21, a support table 22, a steam turbine 23, a condenser 24, a return tank 25, a booster pump 26, a generator 27, a connection pipe 28, and a blocking device 40. The water tank 21 is fixedly installed at the top of the furnace body 10 and is tightly attached to the outer circumferential surface of the chimney 11, so that the heat of the pyrolysis gasification product is conveniently transferred into the water in the water tank 21 through the chimney 11. The water in the water tank 21 is positioned at the lower part of the water tank 21, forming a liquid phase region 212; the air in the water tank 21 is located at the upper portion of the water tank 21, forming a gas phase zone 211. The steam turbine 23, the condenser 24 and the generator 27 are all fixedly mounted on the support table 22. The gas phase area 211 on the upper part of the water tank 21 is communicated with the gas inlet of the steam turbine 23 through a pipeline, the gas outlet of the steam turbine 23 is communicated with the gas inlet of the condenser 24 through a pipeline, the liquid outlet of the condenser 24 is communicated with the water inlet of the return tank 25 through a pipeline, the water outlet of the return tank 25 is communicated with the water inlet of the booster pump 26 through a pipeline, one end of the connecting pipe 28 is communicated with the water outlet of the booster pump 26, and the other end of the connecting pipe is communicated with the gas phase area 211 of the. The booster pump 26 is electrically connected with a control system on the degradation furnace, and a rotating shaft of the generator 27 is connected with a rotating shaft of the steam turbine 23 through a connecting shaft 29.

When the low-temperature magnetization degradation furnace works, pyrolysis gasification products in the furnace body 10 enter the chimney 11, are treated by the flue gas purification unit and then are discharged into the atmosphere. When the pyrolysis gasification product is in the chimney 11, a part of the heat of the pyrolysis gasification product is transferred into the water tank 21, so that the water in the water tank 21 is heated to become water vapor. The steam enters the steam turbine 23 through the first pipeline, drives the blades and the rotating shaft of the steam turbine 23 to rotate, and the rotating shaft of the steam turbine 23 drives the rotating shaft of the generator 27 to rotate under the action of the connecting shaft 29, so that the generator 27 generates electricity during working, and the electricity generated by the generator 27 can be directly connected with electric equipment or stored in a storage battery after being rectified and stabilized. Through the mode, the heat energy generated when the low-temperature magnetization degradation furnace works is utilized to generate electricity, so that the energy utilization rate of the low-temperature magnetization degradation furnace is improved.

The steam entering the steam turbine 23 is discharged from its outlet, cooled by the condenser 24 to become liquid, and enters the return tank 25.

When the low-temperature magnetization degradation furnace works, a part of high-pressure water vapor enters the water outlet of the booster pump 26 from the connecting pipe 28, so that the stable work of the whole power generation system 20 is not facilitated. Therefore, a blocking device 40 is installed inside the other end of the connection pipe 28, and the blocking device 40 prevents the water vapor in the water tank 21 from flowing into the water outlet of the booster pump 26 through the connection pipe 28.

In one embodiment, the other end of the connecting tube 28 is disposed in a longitudinal direction. The middle of the above-mentioned other end of the connection pipe 28 communicates with the gas phase section 211 of the water tank 21 through the return pipe 30.

Specifically, the blocking device 40 includes a piston 41, a spring 42, and a drive mechanism 50. The piston 41 is mounted in the connection pipe 28 and positioned above the other end of the connection pipe 28. The piston 41 is movable up and down within the connecting tube 28 and is kept sealed against the inner wall of the connecting tube 28 by a seal ring. The spring 42 is disposed in the connection pipe 28 and below the piston 41, and one end of the spring 42 is connected to the bottom of the piston 41 and the other end is connected to the support 281 of the inner wall of the connection pipe 28. The spring 42 is preferably a compression spring so that the piston 41 has a tendency to move upwards and the drive mechanism 50 so that the piston 41 has a tendency to move downwards.

When the low-temperature magnetization degradation furnace starts to work, the spring 42 is in a natural extension state, the piston 41 is positioned above the connection part of the connecting pipe 28 and the return pipe 30, and the existence of the piston 41 prevents the water vapor in the water tank 21 from entering the water outlet of the booster pump 26. The liquid discharged from the liquid outlet of the condenser 24 flows into the return tank 25 and gradually accumulates, and after a certain time, the driving mechanism 50 operates to move the piston 41 downward, and when the piston 41 moves below the connection point of the connecting pipe 28 and the return pipe 30, the control system on the degradation furnace controls the operation of the booster pump 26, so that the liquid in the return tank 25 is returned to the water tank 21 through the return pipe 30. After the liquid backflow is completed, the driving mechanism 50 continues to operate, and the piston 41 is reset under the action of the spring 42. After the piston 41 is reset, the driving mechanism 50 performs the next stage of liquid return.

In one embodiment, a stirring shaft 60 is installed in the gas phase region 211 of the water tank 21. The stirring shaft 60 is rotatably connected with the side wall of the water tank 21 through a bearing. The stirring shaft 60 is provided with a plurality of blades 61, the support table 22 is fixedly provided with a speed reducer 70, and an output shaft of the speed reducer 70 is connected with the stirring shaft 60 through a coupler. The input shaft of the speed reducer 70 is provided with a first bevel gear 71, the connecting shaft 29 is provided with a second bevel gear 72, and the second bevel gear 72 is meshed with the first bevel gear 71.

When the rotating shaft of the steam turbine 23 drives the connecting shaft 29 to rotate, the stirring shaft 60 is driven to rotate by the bevel gear structure and the speed reducer 70. The rotation of the stirring shaft 60 causes the blades 61 to stir the water in the water tank 21, so that the water in the water tank 21 is heated more uniformly, the speed and the amount of the generated water vapor in the water tank 21 are increased, and the work efficiency of the whole power generation system 20 is improved.

In the present embodiment, the drive mechanism 50 includes a wire rope 51 and a lug 52. One end of the wire rope 51 is connected with the bottom of the piston 41, and the other end is connected with the inner wall of the tank body after being guided by the guide wheel 213 on the inner wall of the water tank 21. The projection 52 is mounted on the stirring shaft 60,

when the stirring shaft 60 rotates, the projection 52 intermittently contacts the wire rope 51. When the protrusion 52 contacts the wire rope 51, the wire rope 51 is bent, so that the piston 41 is pulled by the one end of the wire rope 51 to move downward, and when the piston 41 moves downward to a position below the connection point of the connection pipe 28 and the return pipe 30, the liquid in the return tank 25 flows back into the water tank 21 through the return pipe 30, thereby completing the return.

Stirring shaft 60 then continues to rotate and wire rope 51 recovers when projections 52 are out of contact with wire rope 51. At this time, the piston 41 is returned by the spring 42. After the piston 41 is reset, the driving mechanism 50 continues to operate, and the next stage of liquid backflow is performed. Therefore, the piston 41 reciprocates up and down once per rotation of the stirring shaft 60, and the liquid flows back once.

The driving mechanism 50 makes full use of the rotation characteristic of the stirring shaft 60, takes the stirring shaft 60 as power, and pulls the piston 41 to move downwards under the action of the second wire rope 51, thereby completing the backflow of liquid. Saves energy and reduces cost.
