As shown in fig. 1-3, the utility model provides a low-temperature magnetization degradation furnace with power generation function, which comprises a furnace body 10 and a power generation system 20. The top of the furnace body 10 is provided with a chimney 11 and a feeding port 12, 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 ℃, 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 40, a return pipe 26, and a generator 27. 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 to form a liquid phase region; the air in the water tank 21 is located at the upper portion of the water tank 21, forming a gas phase zone. The steam turbine 23, the condenser 24 and the generator 27 are all fixedly arranged on the support table 22. The gas phase zone of the upper portion of the water tank 21 communicates with the inlet of the steam turbine 23. The outlet of the turbine 23 communicates with the inlet of the condenser 24. The liquid outlet of the condenser 24 is communicated with the water inlet of the return tank 25. The water inlet of the booster pump 40 is communicated with the water outlet of the return tank 25. The return pipe 26 has one end communicating with the outlet of the booster pump 40 and the other end communicating with the gas phase region of the upper portion of the water tank 21. The rotating shaft of the generator 27 is connected to the rotating shaft of the turbine 23 via a connecting shaft 28.

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 28, 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. The liquid entering the return tank 25 is pressurized by the booster pump 40 and then flows back to the water tank 21 through the return pipe 26, so that the water resource is recycled.

In one embodiment, since the low temperature magnetic degradation furnace is operated, a part of the steam may flow into the water outlet of the booster pump 40 from the return pipe 26, thereby being disadvantageous to the stable operation of the entire power generation system 20.

Therefore, the electromagnetic valve 30 is installed on the return pipe 26, the electromagnetic valve 30 is used for controlling the conduction or the closing of the return pipe 26, and both the electromagnetic valve 30 and the booster pump 40 are electrically connected with the control system on the degradation furnace. The presence of the solenoid valve 30 prevents the water vapor from flowing from the return pipe 26 into the water outlet of the booster pump 40, ensuring stable operation of the entire power generation system 20. When the liquid in the return tank 25 needs to flow back, the control system firstly controls the electromagnetic valve 30 to be opened, then controls the booster pump 40 to work, and pumps the liquid in the return tank 25 into the water tank 21 to complete the recycling of water resources.

In one embodiment, the chimney 11 is made of a thermally conductive material such as copper or silver to facilitate the transfer of heat from within the chimney 11 to the tank 21, such that water within the tank 21 is heated more quickly.

In one embodiment, the interior of the return box 25 is fitted with a heater. The heater can preheat the liquid in the water tank 21 so that the water flowing back into the water tank 21 has a certain temperature, and thus can be heated to a boiling point more quickly.
