[0002] Thermal power generation utilizes the heat generated by the combustion of combustibles and converts it into electricity through a power plant. China is rich in coal resources, and thermal power generation still has great potential. However, thermal power generation produces large amounts of flue gas, which, if not promptly controlled, can cause significant environmental pollution.

[0003] For example, the Chinese utility model patent with the announcement number CN219300778U discloses a boiler flue gas diversion device, the technical solution of which is as follows: it includes a diversion box shell, a feed hopper is installed on the outer wall of the diversion box shell, and a cleaning device for cleaning solid particles is installed on the inner wall of the diversion box shell.

[0004] The applicant has found that there are still some problems that need to be improved in the above technical solution. For example, although the solid particles on the filter plate can be shaken off into the collection box, when the collection box collects too many solid particles, the solid particles in the collection box need to be cleaned, so the collection box needs to be disassembled. The ordinary disassembly method is relatively cumbersome, resulting in a long time spent on disassembling the collection box. For this reason, we propose a boiler flue gas diversion device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 A boiler flue gas diversion device in this embodiment includes a diversion box 1, a square hole is opened on the front of the diversion box 1, a connecting pipe 2 is connected to the left end of the diversion box 1, an air inlet is opened at the right end of the diversion box 1, a diversion fan 3 for accelerating air flow is fixed in the air inlet, a filter screen 4 is provided in the diversion box 1, the square hole is slidably connected to the filter screen 4, a plug hole is opened on the filter screen 4, a cleaning component is provided on the bottom surface of the diversion box 1, and a disassembly component is provided at the left end of the diversion box 1.

[0024] The disassembly assembly includes two connecting blocks 6 fixed on the front of the guide box 1. The two connecting blocks 6 are threaded with screws 7. The diameter of the socket is adapted to the screw 7. The screw 7 is located inside the socket, and a nut 8 is fixed to the left end of the screw 7.

[0025] See also Figure 2 and Figure 3 In order to disassemble and clean the collection box 5, the cleaning assembly in this embodiment includes a collection box 5 connected to the bottom surface of the guide box 1. Two inclined guide plates 9 are also provided at both ends of the inner cavity of the collection box 5. A handle 10 is fixed to the right end of the collection box 5. The cleaning assembly also includes a bracket 11 fixed to the bottom surface of the guide box 1. The bottom surface of the bracket 11 is slidably connected to two limit rods 12. The outer surfaces of the two limit rods 12 are fixed with a stop ring 13, the bottom surface of the stop ring 13 is fixed with a spring 14, and the bottom surfaces of the two limit rods 12 are fixed with handles 15.

[0026] Among them, the cleaning component also includes two mounting blocks 16 fixed on the bottom surface of the guide box 1, and a positioning hole is provided between the two mounting blocks 16. A positioning block 17 is provided between the two mounting blocks 16. The two positioning blocks 17 are respectively slidably connected to the positioning holes. The two positioning blocks 17 are respectively fixed at both ends of the collection box 5. Corresponding sockets are provided on the mounting blocks 16 and the positioning blocks 17. The top surface of the limit rod 12 passes through the mounting block 16 and is inserted into the positioning block 17.

[0027] When the flue gas in the boiler is diverted, the flue gas is first sucked into the diversion box 1 by starting the diversion fan 3. Further, when the flue gas passes through the filter 4, the filter 4 will block the larger particles mixed in the flue gas. The particles will fall downward under the action of gravity and fall into the collection box 5 through the gap between the two guide plates 9, thereby achieving the purpose of blocking the larger particles mixed in the flue gas; and when the collection box 5 contains a large amount of particles and needs to be cleaned, the handle 15 is first pulled downward. When the handle 15 moves downward, it will drive the two limit rods 12 to move downward. Because the outer surface of the limit rod 12 is fixed with two stop rings 13, the stop ring 13 will push the spring when it moves downward. The spring 14 is squeezed, causing the spring 14 to be squeezed and deformed, further causing the limit rod 12 to move out of the socket on the positioning block 17, thereby achieving the purpose of stopping the positioning block 17. After stopping the limiting of the limit block 17, the collection box 5 is disassembled by pulling the handle 10 to the right, and the particulate matter in the collection box 5 is further cleaned. After cleaning, the positioning block 17 is inserted into the positioning hole on the mounting block 16. After inserting it into the appropriate position, by loosening the handle 15, under the elastic action of the two springs 14, the top end of the spring 14 pushes the gear ring 13, driving the gear ring 13 to move upward, so that the limit rod 12 fixed inside the gear ring 13 is reinserted into the socket, thereby restoring the limit to the collection box 5.

[0028] See also Figure 1 In order to clean the filter 4 when it is blocked, the nut 8 is turned to unscrew the screw 7 out of the connecting block 6, so that the screw 7 is moved out from the limiting hole opened at the left end of the filter 4, thereby stopping the limiting of the filter 4. The filter 4 can be further pulled out to clean or replace the filter 4.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
