Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery equipment, specifically to waste heat recovery and reuse equipment for thermal power generation. Background Technology

[0002] Waste heat recovery and reuse equipment for thermal power generation is a type of device system used to collect and convert the waste heat generated during the production process of thermal power plants, and then convert it back into usable energy (such as electricity and heat). Its core function is to improve energy utilization efficiency, reduce energy waste, and simultaneously lower carbon emissions. Waste heat recovery from thermal power generation mainly relies on recovering the waste heat from the exhaust gases produced by thermal power generation.

[0003] Chinese Patent Publication No. CN223204360U discloses a waste gas treatment device with waste heat recovery, which includes a waste gas combustion tower. The outer wall of the waste gas combustion tower is provided with a jacketed water chamber, and the inner wall of the jacketed water chamber is provided with a first temperature sensor. The water inlet at the top of the jacketed water chamber is connected to a water supply device through one of the inlets of a two-inlet-one-outlet three-way valve and a water pipe. The water outlet at the bottom of the jacketed water chamber is connected to the water inlet of a water tank through a water pipe and a first water pump. The jacketed water chamber on the outer wall of the waste gas combustion tower of the waste gas treatment device with waste heat recovery disclosed in this utility model can intelligently wait for the water inside to heat up to a certain temperature before replacing it with new water and continuing to utilize waste heat. When the water temperature in the water tank is not high enough, water in the water tank is pumped into the jacketed water chamber for continued heating to maintain the temperature of the water in the water tank.

[0004] However, the waste gas treatment equipment with waste heat recovery disclosed in the above patent still has certain shortcomings in actual use. Since the waste gas produced in the waste gas combustion tower contains a large amount of soot, and the above equipment does not have a filter structure that is easy to disassemble and replace at the air inlet, soot can easily enter the equipment and affect its service life. Summary of the Invention

[0005] The purpose of this invention is to provide a waste heat recovery and reuse device for thermal power generation, in order to solve the problem mentioned in the background art that the existing equipment does not have a filter structure that is easy to disassemble and replace at the air inlet, which makes it easy for smoke and dust to enter the equipment and affect the service life of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste heat recovery and reuse device for thermal power generation, including a recovery device and an air inlet pipe connected to the recovery device. An arc-shaped cover plate is movably installed on the body of the air inlet pipe. Multiple fixing plates are equidistantly fixed on the inner wall of the arc-shaped cover plate. A filter screen is provided on one side of the fixing plate. The surface of the filter screen has threaded holes. A positioning bolt is connected between the fixing plate and the threaded holes. Two symmetrically distributed inserts are fixed on the outer wall of the arc-shaped cover plate. Limiting holes are provided on the surface of the inserts. A limiting mechanism is provided on the body of the air inlet pipe for fixing and disassembling the air inlet pipe and the arc-shaped cover plate.

[0007] Preferably, the limiting mechanism includes a fixing block and a slot. Two fixing blocks are symmetrically arranged and fixed to the outer walls of the two sides of the intake pipe respectively. The slot is opened on the top wall of one end of the fixing block, and the insert is movably inserted into the cavity of the slot.

[0008] Preferably, the limiting mechanism further includes a cavity, a crossbar, and a movable plate. The cavity is formed on one side of the fixed block. The two ends of the crossbar are respectively fixed to the two side walls of the bottom inner cavity of the cavity. The movable plate is movably sleeved on the surface of the crossbar.

[0009] Preferably, the limiting mechanism further includes a push rod, a limiting rod, and a spring. The limiting rod is fixedly installed on the top side wall of the movable plate, and the rod body of the limiting rod movably penetrates the groove wall of the slot and is movably inserted into the cavity of the limiting hole. The spring is sleeved on the surface of the crossbar, and the spring is located on the side of the movable plate away from the slot. The push rod is located at the bottom of the air inlet pipe, and the two ends of the push rod are fixedly connected to the bottom walls of the two movable plates respectively.

[0010] Preferably, the mesh size of the filter screen decreases from left to right.

[0011] Preferably, a handle is fixedly installed on the outer wall of the middle part of the arc-shaped cover plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features an arc-shaped cover plate installed on the air intake pipe. Multiple filter screens with different mesh sizes are fixed within the cover plate using a fixing plate and positioning bolts. This allows dust particles in the exhaust gas introduced into the recovery equipment through the air intake pipe to be intercepted by the filter screens, preventing them from entering the recovery equipment and affecting its lifespan. Furthermore, for easy replacement or cleaning of the filter screens after prolonged use, a limiting mechanism allows for easy removal. To disassemble the filter screens, a push rod can be moved to the right, causing a movable plate within the cavity to move along a crossbar. During this movement, the plate compresses a spring and pulls a limiting rod out of the limiting hole on the insert surface. The arc-shaped cover plate can then be lifted by the handle, allowing the filter screens to be removed from the air intake pipe. By removing the positioning bolts, the filter screens can be quickly removed for cleaning or replacement. This simple operation facilitates rapid filter screen removal and replacement, ensuring successful dust filtration. Attached Figure Description

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.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: a waste heat recovery and reuse equipment for thermal power generation, including a recovery device 1 and an air inlet pipe 2 connected to the recovery device 1. An arc-shaped cover plate 3 is movably installed on the pipe body of the air inlet pipe 2. Multiple fixing plates 15 are equidistantly welded to the inner wall of the arc-shaped cover plate 3. A filter screen 14 is set on the right side of the fixing plate 15. A threaded hole 18 is opened on the surface of the filter screen 14. A positioning bolt 16 is connected between the fixing plate 15 and the threaded hole 18, the purpose of which is to fix the fixing plate 15 and the filter screen 14 together. Two symmetrically distributed inserts 8 are welded to the outer wall of the arc-shaped cover plate 3. A limiting hole 17 is opened on the surface of the insert 8. The limiting mechanism is used for fixing and disassembling the air inlet pipe 2 and the arc-shaped cover plate 3, and it is set on the pipe body of the air inlet pipe 2.

[0021] The limiting mechanism includes a fixed block 5 and a slot 7. Two fixed blocks 5 are symmetrically arranged and welded to the outer walls of the two sides of the intake pipe 2. The slot 7 is opened on the top left wall of the fixed block 5, and the insert 8 is movably inserted into the cavity of the slot 7. The limiting mechanism also includes a cavity 6, a crossbar 12, and a movable plate 9. The cavity 6 is opened in the right side body of the fixed block 5. The left and right ends of the crossbar 12 are welded to the bottom inner walls of the cavity 6. The movable plate 9 is movably sleeved on the surface of the crossbar 12, that is, the movable plate 9 can move along the crossbar 12. The limiting mechanism also includes a push rod 10, a limiting rod 11, and a spring 13. The limiting rod 11 is welded to the top left side wall of the movable plate 9, and the rod of the limiting rod 11 movably passes through... The insertion rod 11 passes through the cavity wall of the slot 7 and is movably inserted into the cavity of the limiting hole 17. When the limiting rod 11 is inserted into the limiting hole 17, the insertion post 8 is fixed in the slot 7 and cannot be pulled out. The spring 13 is sleeved on the surface of the crossbar 12 and the spring 13 is located on the side of the movable plate 9 away from the slot 7. The purpose is to enable the movable plate 9 to automatically reset. The push rod 10 is located at the bottom of the air inlet pipe 2. The front and rear ends of the push rod 10 are welded to the bottom walls of the two movable plates 9 respectively. The purpose is to facilitate the simultaneous movement of the two movable plates 9 by the push rod 10. The mesh size of the filter screen 14 decreases from left to right. The purpose is to improve the filtration effect of the smoke and dust in the exhaust gas. The handle 4 is welded to the outer wall of the middle part of the arc-shaped cover plate 3.

[0022] Working principle: By installing an arc-shaped cover plate 3 on the air intake pipe 2, multiple filter screens 14 with different mesh sizes are fixed inside the arc-shaped cover plate 3 by a fixing plate 15 and positioning bolts 16. This allows the dust particles in the exhaust gas introduced into the recycling equipment 1 through the air intake pipe 2 to be intercepted by the filter screens 14, preventing them from entering the recycling equipment 1 and affecting its service life. Furthermore, after prolonged use of the filter screen 14, to facilitate its replacement or cleaning, the limiting mechanism allows for easy disassembly of the filter screen 14. The push rod 10 can be moved to the right, causing the movable plate 9 within the cavity 6 to move along the crossbar 12. During this movement, the plate 9 compresses the spring 13 and pulls the limiting rod 11 out of the limiting hole 17 on the surface of the insert post 8. Then, the arc-shaped cover plate 3 can be lifted via the handle 4, allowing the filter screen 14 to be removed from the air intake pipe 2. By removing the positioning bolt 16, the filter screen 14 can be quickly disassembled for cleaning or replacement. This simple operation facilitates rapid disassembly and replacement of the filter screen 14, ensuring smooth filtration of smoke and dust.
