Description

Technical Field

[0001] The utility model relates to the technical field of waste heat power generation, in particular to waste heat power generation equipment. Background Art

[0002] Waste heat power generation is a technology that converts excess heat energy in the production process into electrical energy. Waste heat power generation is not only energy-saving, but also beneficial to environmental protection. An important equipment for waste heat power generation is the waste heat boiler, which uses the heat or combustible materials in waste gas, waste liquid and other working fluids as a heat source to produce steam for power generation.

[0003] According to the patent publication number CN217441613U, a waste heat power generation device is disclosed. The waste heat power generation device comprises a furnace body and a fixed shell, the fixed shell is fixedly connected to the right side of the interior of the furnace body, a disassembly device is arranged inside the fixed shell, a cleaning device is arranged below the interior of the furnace body, a water tank is fixedly connected to the top of the furnace body, the bottom of the water tank is connected to three heat collection pipes, one side of the water tank is connected to the steam turbine, and the outer wall of the steam turbine is fixedly connected to the furnace body through a bracket.

[0004] The above solution solves the problem that the interior of the waste heat power generation equipment will become blackened due to long-term use and the cleaning is cumbersome. However, the above solution still has certain limitations: given that the above device fails to include an effective cleaning mechanism for the scale on the inner wall of the heat collection tube in the design, this omission causes the scale to gradually accumulate on the inner wall of the heat collection tube, forming a dense and difficult-to-remove non-metallic layer. This layer of scale not only occupies the surface area originally used for heat conduction, but also due to its own low thermal conductivity, the heat conduction efficiency of the heat collection tube is significantly reduced. To this end, we provide a waste heat power generation device to solve the above problems. Utility Model Content

Through the cleaning mechanism 4 and the heat collection tube 3, in actual application, the carefully designed cleaning mechanism 4 can effectively remove the scale accumulated on the inner wall of the heat collection tube 3. This measure avoids the scale occupying the surface area originally used for efficient heat conduction, greatly guarantees the heat conduction efficiency of the heat collection tube 3, and ensures its continuous and efficient performance.

[0027] Two symmetrical supporting legs are fixed to the bottom of the furnace body 1, which can separate the furnace body 1 from the ground at a certain distance to prevent the furnace body 1 from being corroded by moisture from the bottom. A water filling hole is opened on the upper surface of the water tank 2, and a plug is connected to the internal thread of the water filling hole.

[0028] The bottom surface of the water tank 2 is fixedly connected to two symmetrical heat collection tubes 3, the outer surfaces of the two heat collection tubes 3 are fixedly connected to the interior of the furnace body 1, the interiors of the two heat collection tubes 3 are provided with cleaning mechanisms 4, the interior of the furnace body 1 is provided with a sealing mechanism 5, the outer surface of the furnace body 1 is fixedly connected to an air intake pipe 6, the right side of the furnace body 1 is provided with a connecting mechanism 7, the right side of the furnace body 1 is provided with an air guide pipe 8, the outer surface of the furnace body 1 is fixedly connected to an exhaust pipe 9, and a power generation component 10 is provided above the furnace body 1.

[0029] The power generation component 10 includes a steam duct connected to the water tank 2, a steam turbine and a steam turbine mounting frame. The power generation principle of this device is: the flue gas enters the furnace body 1 through the air guide pipe 8 and the air inlet pipe 6. When the flue gas flows through the heat collection tube 3, the water inside the heat collection tube 3 will exchange heat with the flue gas, thereby intercepting the heat in the flue gas and heating the water inside the water tank 2. The generated water vapor provides power for the steam turbine in the power generation component 10, and the steam turbine will generate electric current.

[0033] The scraper 405 fits tightly against the inner wall of the heat collection tube 3. The sealing ring 406 is made of a material with good sealing performance, wear resistance and high temperature resistance. The sealing ring 406 can seal the gap between the rotating shaft 402 and the collection cover 401 to prevent water in the heat collection tube 3 from flowing out of the gap.

[0034] When in use, the handle 403 is rotated to drive the rotating shaft 402 to rotate inside the collecting cover 401, drive the sealing ring 406 to rotate, drive the connecting block 404 to rotate, and drive the scraper 405 to rotate.

[0040] The outer surface of the first connecting pipe 702 is connected to the inner thread of the air intake pipe 6 , the second connecting pipe 704 is fixedly connected to the inner part of the sleeve 701 , and the outer surface of the second connecting pipe 704 is connected to the inner thread of the air guide pipe 8 .

After cleaning, it can be reinstalled. This measure avoids the scale occupying the surface area originally used for efficient heat conduction, greatly guarantees the heat conduction efficiency of the heat collection tube 3, and ensures its continuous and efficient performance.
