Description

Technical Field

[0001] This utility model relates to the field of pyrolysis gasification power generation technology, specifically a municipal solid waste pyrolysis gasification power generation device. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the amount of domestic waste generated has increased dramatically. Traditional landfill and incineration methods face problems such as large land occupation, serious secondary pollution (e.g., leachate, dioxins, fly ash), and low resource utilization. Pyrolysis gasification technology, as an emerging waste treatment method, can convert organic matter into combustible gases (e.g., hydrogen, carbon monoxide, methane) under anaerobic or oxygen-deficient conditions. These gases can be used for power generation, thereby achieving waste reduction, harmlessness, and resource recovery. Most existing municipal solid waste pyrolysis gasification devices have some problems in actual use. Municipal solid waste has a complex composition and varied forms. Since they mostly adopt a fixed-position feeding method, blockages are prone to occur during feeding, resulting in uneven material distribution, which affects the stability and efficiency of pyrolysis gasification. Secondly, in the pyrolysis tank, the material is prone to accumulation or agglomeration, resulting in uneven heat transfer. Some areas are overheated while others are not fully reacted, which not only reduces the gas production rate and power generation efficiency, but may also produce harmful substances due to local high temperature. Therefore, we propose a municipal solid waste pyrolysis gasification power generation device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a municipal solid waste pyrolysis gasification power generation device. The device uses a rotating cutting blade to further cut and crush the incoming municipal solid waste, and a rotating conical plate to evenly feed the waste into the processing tank to improve the efficiency of pyrolysis gasification. At the same time, a gas flow valve controls the gas entering the processing tank and a rotating stirring rod solves the problem of insufficient pyrolysis gasification in local areas. This device can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a municipal solid waste pyrolysis gasification power generation device, comprising a bottom shell and a material equalization unit; Bottom shell: A processing tank is fixed on the top surface, and an exhaust pipe is connected to the top surface of the processing tank. An upwardly protruding conical base is fixed on the bottom surface of the processing tank. Ash discharge grooves corresponding to and connected to the bottom shell are opened at both ends of the surface of the conical base. A temperature control unit is provided on the surface of the processing tank. The material equalization unit includes a motor, a frame, a rotating shaft, a conical rotating plate, a material equalization shell, and a discharge chute. The frame is fixed to the top surface of the processing tank, and the motor is mounted on the surface of the frame. The bottom end of the motor is connected to the top end of the rotating shaft. The material equalization shell is fixed to the top surface inside the processing tank. Feed shells are fixed to both the left and right sides of the material equalization shell. An upwardly protruding conical rotating plate is fixed to the outside of the rotating shaft. The top surface of the conical rotating plate is in contact with the bottom surface of the material equalization shell. Discharge chute is provided at both ends of the surface of the conical rotating plate. The system also includes a controller, which is fixed to the front side of the base. The input terminal of the motor is electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power source.

[0005] The conical rotating plate driven by the motor rotates on the bottom surface of the equalization shell, so that the garbage entering from the two side feed shells is evenly discharged from the discharge chute, which effectively avoids the problem of blockage at the feed inlet and ensures the continuity and efficiency of subsequent pyrolysis and gasification of municipal solid waste.

[0006] Furthermore, the equalization unit also includes gears, toothed wheels, fixed shafts, cutter holders, and cutting blades. The gears are fixed to the outside of the rotating shaft and located on the upper side of the equalization shell. There are two fixed shafts, each rotatably installed in one of the two shaft holes on its top surface. Toothed wheels are fixed to the top of each of the two fixed shafts, and the toothed wheels mesh with the gears. Cutter holders are evenly fixed to the outside of the fixed shafts, and cutting blades are installed on the surface of the cutter holders. The gears mesh with the toothed wheels to drive the cutting blades on the fixed shafts to rotate. This allows the municipal solid waste to be cut and crushed when it enters the equalization shell, resulting in more uniform heating and more complete reaction during the subsequent pyrolysis process, thereby significantly improving gasification efficiency and the yield of combustible gases.

[0007] Furthermore, the material equalization unit also includes a support, stirring rods, and scrapers. The top surface of the support is connected to the bottom end of the rotating shaft at the center. Stirring rods are evenly installed on both sides of the bottom surface of the support. The bottom end of the stirring rod is connected to the top surface of the scraper. The scraper is inclined and its bottom surface is in contact with the top surface of the conical base. The stirring rods can continuously stir the waste being pyrolyzed in the tank to prevent the waste from accumulating and clumping, thus ensuring the uniform transfer of heat and matter and making the waste pyrolysis more thorough. The scraper can continuously scrape off the ash and coke adhering to the conical base to increase the efficiency of ash removal.

[0008] Furthermore, the temperature control unit includes an annular tube, a gas flow valve, a jet nozzle, a gas pipe, a gas pump, a mounting base, and an igniter. There are two annular tubes, each installed at one end of the outer side of the treatment tank. The inner side of the annular tube is uniformly connected with jet nozzles, which are inserted into vent holes on the surface of the treatment tank. The inlet pipe of the annular tube is connected to one end of the gas flow valve, and the other end of the gas flow valve is connected to the outlet of the gas pipe. The inlet of the gas pipe is connected to the outlet of the gas pump. The mounting base is located on the surface of the treatment tank, and an igniter is installed on the end face of the mounting base. The input ends of the gas flow valve, gas pump, and igniter are electrically connected to the output end of the controller. Activating the gas pump supplies gas through the annular tube to multiple points inside the treatment tank, and the gas flow valve adjusts the gas flow rate in real time. Activating the igniter ignites the municipal solid waste, maintaining the temperature and oxygen concentration during the pyrolysis and gasification process within the optimal range, thereby ensuring the efficient production of combustible gas.

[0009] Furthermore, the temperature control unit also includes an oxygen sensor and a temperature sensor. The oxygen sensor is installed on the front side of the top of the treatment tank, and the temperature sensor is installed on the surface of the treatment tank. The output terminals of the oxygen sensor and the temperature sensor are electrically connected to the input terminal of the controller. The oxygen sensor and the temperature sensor can detect the amount of oxygen and the temperature inside the treatment tank, thereby facilitating timely adjustments by personnel.

[0010] Furthermore, it also includes a collection shell and a conveyor. The collection shell is fixed inside the bottom shell, and the conveyor is installed on the bottom surface inside the bottom shell and located below the discharge port at the bottom of the collection shell. The input end of the conveyor is electrically connected to the output end of the controller. The collection shell can concentrate the discharged ash and slag onto the surface of the conveyor, thereby avoiding the time-consuming and laborious problem of manual ash cleaning.
