[0002] Garbage incineration power generation refers to the power generation form that through the special incineration boiler combustion municipal solid waste, and through the steam turbine generator set power generation. Specifically, garbage incineration power generation is the work that garbage incineration plant and garbage incineration equipment are introduced and are digested and absorbed and re-innovated. It mainly is to properly incinerate various garbage, and then utilizes the heat energy generated in this process to convert into electric energy. This way not only can solve the predicament of garbage accumulation to a certain extent, but also can turn waste into treasure and create clean power resources.

[0003] Garbage incineration power generation can produce a large amount of flue gas, and the flue gas contains a large amount of heat. When a heat exchanger is used to recycle and utilize the heat in the flue gas, since the flue gas contains a large amount of impurity dust, directly introducing into the heat exchanger can cause the heat exchanger to be blocked, and at the same time can cause the impurity dust to adhere to the heat exchanger, so that the heat exchange efficiency of the heat exchanger is reduced. Using a filtering device to filter the flue gas can cause the filter screen to be blocked after a long time of filtering, so that the filtering effect is reduced, and it is inconvenient to clean the impurity dust on the filter screen.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 6 The present invention provides an embodiment of a heat recovery device for waste incineration power generation, comprising a heat exchanger 1, a spring 18 and a threaded rod 22. A pipe 4 is installed on one side of the upper end of the outer wall of the heat exchanger 1. A pipe 3 15 is connected to the top end of the pipe 4. A housing 2 is fixed to the upper end of the pipe 3 15. An installation hole 2 14 is provided on the lower surface of the housing 2. The upper end of the outer wall of the pipe 3 15 extends into the installation hole 2 14 and is fixed. The installation hole 2 14 facilitates the insertion and fixing of the pipe 3 15.

[0023] The upper surface of the housing 12 has a groove 12, into which a sealing cover 7 is inserted. The upper surface of the sealing cover 7 has a mounting hole 13, into which a pipe 2 8 extends. Handles 1 9 are fixed to the front and rear ends of the upper surface of the sealing cover 7. By inserting the sealing cover 7 into the groove 12, the housing 15 can be sealed. The mounting hole 13 facilitates the insertion and fixing of the pipe 2 8, which guides the flue gas into the housing 15 for filtration. The bottom of the inner wall of the groove 12 has a housing 15. The sides of the housing 12 are respectively... A through slot 11 is provided, and a bracket 6 is inserted into the through slot 11. The bracket 6, the second housing 10, the spring 18, and the pull rod 19 are horizontally aligned. By aligning the bracket 6, the second housing 10, the spring 18, and the pull rod 19 horizontally, it is easy to pull the bracket 6 and prevent the bracket 6 from getting stuck. An installation slot 16 is provided on the upper surface of the bracket 6. A filter screen 17 is fixed on the inner wall of the installation slot 16. The filter screen 17 can filter impurities and dust in the flue gas, which facilitates the heat exchanger 1 to recover the heat from the flue gas after filtering the dust.

[0024] Box 10 is fixed to one side of box 1 (2). Box 10 has a groove 21 on one side. One side of spring 18 is fixed to bracket 6, and the other side of spring 18 is fixed to the inner wall of groove 21. When the threaded rod 22 is removed from the threaded hole 23 and threaded groove 26, spring 18 can be elastically deformed. Bracket 6 and filter screen 17 can be moved out from through groove 11 as needed, which facilitates cleaning of dust and impurities on filter screen 17 and prevents dust and impurities from accumulating and causing blockage, thus reducing filtration efficiency. A pull rod 19 is fixed to one side of bracket 6. One side of pull rod 19 passes through box 10, and the other side of box 10 has a through hole 20. One side of pull rod 19 passes through through hole 20, which facilitates the movement of pull rod 19. 9 penetrates the housing 10 to facilitate pulling the pull rod 19. A mounting plate 25 is fixed to one side of the pull rod 19, and a handle 24 is fixed to one side of the mounting plate 25. The handle 24 facilitates pulling the mounting plate 25 and the bracket 6. Fixing plates 3 are fixed at the front and rear ends of the bracket 6. Threaded grooves 26 are opened at the front and rear ends of the mounting plate 25. A threaded hole 23 is opened at the front end of the fixing plate 3. The rear end of the threaded rod 22 passes through the threaded hole 23 and extends into the threaded groove 26 and is threaded. The threaded rod 22 passes through the threaded hole 23 and extends into the threaded groove 26 and is threaded, which facilitates the restriction of the mounting plate 25 and the bracket 6, and at the same time facilitates the removal of the bracket 6 from the through groove 11 for dust cleaning.

[0025] When it is necessary to recover the waste heat from the flue gas generated by waste incineration power generation, the flue gas is introduced into the tank 5 through pipe 28. The filter screen 17 can filter impurities and dust in the flue gas. The filtered flue gas then enters the heat exchanger 1 for heat recovery. After long-term use, a large amount of impurities and dust will accumulate on the filter screen 17, resulting in poor filtration effect. Therefore, the threaded rod 22 is removed from the threaded groove 26 and threaded hole 23, and the spring 18 is elastically deformed, allowing the bracket 6 to move out from the through groove 11 to clean the impurities and dust on the filter screen 17. This achieves the effect of preventing dust and impurities in the flue gas from entering the heat exchanger 1, and at the same time, the dust filtration device is easy to clean, saving time and effort.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
