[0001] The utility model relates to the field of cogeneration power, in particular to a cogeneration power self - supply device. Background Art

[0002] Cogeneration power, also known as combined heat and power production or co - generation, is a highly efficient way of energy utilization. It uses the waste heat generated during the power generation process by fuels (such as gas, oil and gas, etc.). Through a heat recovery device, the waste heat is converted into useful heat energy, and at the same time, electric energy is also generated. This comprehensive energy utilization method can not only meet the demands of heat supply and power supply, but also improve the energy utilization efficiency and reduce carbon emissions, having important economic and environmental benefits. A cogeneration system usually consists of a fuel supply system, a waste heat recovery device, a heat energy utilization system, a control system, etc. The waste heat recovery recovers and utilizes the waste heat generated during the power generation process. The control system monitors and regulates the entire cogeneration system to ensure the safe and stable operation of the system. Cogeneration power is an efficient, energy - saving and environmentally friendly energy utilization method, having broad application prospects and important economic and environmental benefits. A cogeneration power self - supply device, also known as co - generation, is a technology that uses a heat engine to simultaneously generate electricity and useful heat during the power generation process. This technology converts the waste heat generated during the power generation process into useful heat energy through a heat recovery device for the use of the heating system. This comprehensive energy utilization method can not only meet the demands of heat supply and power supply, but also improve the energy utilization efficiency and reduce carbon emissions, having important economic and environmental benefits.

[0003] According to the Chinese patent with the publication number: CN2861824Y, a cogeneration power self - supply device is provided.

One end of the cylinder 6 is fixedly connected with a threaded pipe 12. One end of the threaded pipe 12 is fixedly connected with an output pipe 13. An air outlet pipe 14 is installed on the output pipe 13.

[0025] In use, when the exhaust gas enters the air outlet pipe 14 from the gas storage device 24, then start the water pump 3 to suck water from the input pipe 4. Then the water enters the pipeline 5 from the water pump 3, and then the water in the pipeline 5 continues to enter the cylinder 6. At this time, rotate the handle 9 to drive the rotating shaft 10 to rotate, and then the rotating shaft 10 drives the limiting plate 11 to rotate. At this time, rotate the limiting plate 11 to a suitable position and insert the fixing rod on the handle 9 into the fixed slot 8 on the fixed cylinder 7 to control the flow rate of the water so that the outflow rate of the water in the air outlet pipe 14 becomes lower.

After using for a period of time, the filter plate 17 can be taken out along the sliding groove 16 for flushing. Then, the filter plate 17 can be moved outwards by the thickening plate 21. At this time, the thickening plate 21 drives the moving rod 19 to move outwards, and then the moving rod 19 drives the scraping plate 20 to slide on the filter plate 17.
