Description

Technical Field

[0001] The invention relates to the technical field of garbage incineration power generation, and in particular to a garbage incineration power generation device with automatic feeding. Background Art

[0002] In recent years, incineration has been increasingly valued as the mainstream treatment measure for domestic waste at home and abroad. With the strengthening of the public's awareness of environmental protection, the improvement of incineration technology and equipment, and the gradual implementation of the garbage classification system, domestic waste incinerators are also developing in the direction of large capacity, high calorific value, and high parameters, which can save floor space and unit investment and improve unit efficiency.

[0003] At present, when garbage incineration power generation devices are working, most of them put garbage directly into the combustion furnace for combustion. The combustion speed is slow, and incomplete combustion often occurs, resulting in low heat utilization rate. For this reason, some devices use the method of crushing the garbage before adding it to the combustion furnace. However, at present, most of the feeding into the combustion furnace is not continuous. Generally, it is added once when it is needed according to the remaining garbage fuel in the combustion furnace, and then added again after the garbage fuel in the furnace is burned to a certain extent. The operation is cumbersome, and the combustion speed is slow after each addition of materials. It will also cause large fluctuations in temperature and water temperature in the furnace, affecting the power generation efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a garbage incineration power generation device with automatic feeding.

[0026] The water outlet pipe 12 is connected to a depressurizing furnace, the exhaust pipe of the depressurizing furnace is connected to a water vapor separation device, the outlet pipe of the water vapor separation device is connected to a power generation device, and the water outlet pipe of the water vapor separation device is connected to the water inlet pipe 11 for recycling;

[0027] The waste incineration power generation device comprises a control processor, and the receiver 4, the feeding motor 7, the primary combustion igniter 13, the secondary combustion igniter 14, and the fan 17 are all electrically connected to the control processor.

[0028] When in use, the garbage incineration power generation device is arranged and constructed on site, and the garbage is poured into the feed hopper 1. The garbage is crushed by the crushing mechanism and then enters the temporary storage hopper 2. The feeding motor 7 drives the auger feeding mechanism 5 to work, and the crushed garbage is transported to the top of the incinerator 8, and enters the incinerator 8 through the feeding port 9. Among them, the primary combustion igniter 13 and the secondary combustion igniter 14 in the incinerator 8 are ignited to ignite the crushed garbage, and the garbage is burned in the incinerator 8. The garbage that enters later falls under its own weight and is dispersed under the action of the hot air flow, so that it can be fully burned, and part of the volume Larger garbage or garbage that has not been fully burned falls onto the partition 15 and continues to burn above the partition 15 until it is burned into ash. The fan 17 blows air into the incinerator 8 to increase the amount of oxygen in the furnace and blow up the ash on the partition 15 to prevent the ash from clogging the partition 15. It also further increases the airflow in the furnace, which is conducive to the full combustion of the garbage as it falls. The heat generated by the burning of the garbage heats the hot water in the hot water boiler 10. The water in the hot water boiler 10 is under high pressure and the water has not vaporized at this time. When the water enters the step-down furnace through the outlet pipe 12, it vaporizes after the pressure is reduced. The water vapor enters the steam generator through the outlet pipe to generate electricity.

The active pulverizing roller 20 is driven to rotate by the pulverizing motor, and the driven pulverizing roller 21 is driven to rotate through the meshing transmission of the active gear 22 and the driven gear 23, and the active pulverizing roller 20 cooperates with the driven pulverizing roller 21 to crush the garbage and drop it into the temporary storage hopper 2. Among them, if the garbage in the temporary storage hopper 2 reaches a certain height, the light emitter 3 will be covered. At this time, the light emitted by the light emitter 3 cannot be received by the receiver 4, and each device works normally. If the amount of garbage in the temporary storage hopper 2 is small, that is, the light emitter 3 is not covered, the light emitted by the light emitter 3 is received by the receiver 4, and the control processor sends an instruction to stop each device from working. The staff checks the situation and adds garbage to the feed hopper 1 in time to avoid the waste incineration power generation device running idle when there is no garbage.

[0030] In this specific embodiment, a support frame 24 is provided at the lower end of the hot water boiler 10, a stop valve is provided on the slag discharge port 18, and an ash box 25 is provided below the slag discharge port 18.
