Description

Technical Field

[0001] This utility model relates to the fields of environmental protection and new energy technology, specifically a low-temperature connected incinerator power generation structure. Background Technology

[0002] Waste incineration power generation works by collecting the high-temperature heat generated from waste incineration in a waste heat recovery boiler. The heat is then used to heat the water inside the boiler, and the steam generated in the boiler is transported through pipes to a steam generator. The steam generator is then driven to generate electricity. Therefore, the incinerator needs to use a connection structure to transfer heat to the waste heat boiler so that steam can be generated inside the waste heat boiler.

[0003] However, existing low-temperature incinerator power generation structures typically use several curved, serpentine pipes to flow low-temperature water through the pipes carrying the high-temperature flue gas when absorbing heat from the high-temperature flue gas. This allows the low-temperature water to absorb heat and be heated while flowing. Furthermore, because water is prone to heavy metal precipitation during prolonged heating, scale easily forms in the pipes transporting the low-temperature water, leading to blockages and hindering the water's ability to absorb heat while flowing. In addition, cleaning the scale in the water pipes is troublesome and time-consuming, affecting the normal operation of the power generation structure. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature connected incinerator power generation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature incinerator power generation structure, comprising an outer shell, a steam outlet pipe penetrating the middle of the top of the outer shell, a cavity formed inside the outer shell, a sedimentation tank formed at the bottom of the cavity, a water inlet pipe penetrating the top of one side wall of the outer shell, multiple drip nozzles penetrating the bottom of the water inlet pipe, an air inlet pipe penetrating the bottom of one side wall of the outer shell, a vertical rod fixedly connected to the top of the air inlet pipe, heat-conducting plates fixedly connected to both sides of the vertical rod, a serpentine tube embedded inside the heat-conducting plate, a sliding frame provided on the outer side of the heat-conducting plate, a brush plate fixedly connected to the inner wall of the sliding frame, an air outlet pipe penetrating the top of the other side wall of the outer shell, and a scale discharge pipe penetrating the bottom of the front side of the outer shell.

[0006] Preferably, electric cylinders are fixedly installed on both sides of the top of the outer shell, and fixed plates are fixedly connected to both sides of the slide frame. The output end of the electric cylinder is fixedly connected to the slide frame through the fixed plates.

[0007] Preferably, the sliding frame is slidably connected to the heat-conducting sheet via an electric cylinder, and the brush plate is slidably connected to the heat-conducting sheet via the sliding frame.

[0008] Preferably, the water outlet of the drip nozzle is located at the top of the heat-conducting plate, and the end of the water inlet pipe has a water outlet pipe that communicates with the interior of the cavity.

[0009] Preferably, the bottom end of the serpentine tube communicates with the interior of the air inlet pipe, the top end of the serpentine tube communicates with the interior of the air outlet pipe, and the bottom end of the air outlet pipe is fixedly connected to the vertical rod.

[0010] Preferably, the bottom of the sedimentation tank is provided with a groove, which is connected to the scale discharge pipe.

[0011] Preferably, a solenoid valve is installed at the inlet of the scale discharge pipe.

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

[0013] 1. This low-temperature incinerator power generation structure, through a serpentine tube, heat-conducting plates, water inlet pipe, drip nozzle, and cavity, allows high-temperature flue gas to flow along the serpentine tube when entering the structure. During the flow, the heat-conducting plates release heat to the water in the cavity, causing the water in the cavity to evaporate after absorbing heat and produce water vapor. This prevents scale from forming when the water is heated from entering the conveying pipe of this power generation structure, thereby reducing the probability of blockage in the conveying pipe and making it more conducive to the low-temperature water absorbing heat while flowing.

[0014] 2. This low-temperature incinerator power generation structure, through a sliding frame, brush blades, and electric cylinder, allows the brush blades to slide and wipe along the outer surface of the heat-conducting plate when scale accumulates on the outer surface. This scrapes the scale off the outer surface of the heat-conducting plate and places it in the sedimentation tank for subsequent discharge, saving time on scale cleaning within the structure and reducing adverse effects on the normal use of the power generation structure.

[0023] like Figures 1 to 4As shown, the low-temperature connected incinerator power generation structure of this embodiment includes an outer shell 1. A steam outlet pipe 7 passes through the middle of the top of the outer shell 1. A cavity 14 is opened inside the outer shell 1. A sedimentation tank 15 is opened at the bottom of the cavity 14. A water inlet pipe 3 passes through the top of one side wall of the outer shell 1. Multiple drip nozzles 8 pass through the bottom of the water inlet pipe 3. An air inlet pipe 4 passes through the bottom of one side wall of the outer shell 1. A vertical rod 13 is fixedly connected to the top of the air inlet pipe 4. Heat-conducting plates 10 are fixedly connected to both sides of the vertical rod 13. A serpentine tube 11 is embedded inside the heat-conducting plate 10. A sliding frame 9 is provided on the outside of the heat-conducting plate 10. A brush plate 18 is fixedly connected to the inner wall of the sliding frame 9. An air outlet pipe 6 passes through the top of the other side wall of the outer shell 1. A scale discharge pipe 5 passes through the bottom of the front side of the outer shell 1.

[0024] Specifically, the outer wall of the outer shell 1 is also covered with a heat insulation structure, which makes it difficult for the heat of the high-temperature flue gas to be lost through the outer shell 1, thereby improving the heat conversion efficiency of this power generation structure. The function of the steam outlet pipe 7 is to allow the water vapor generated by the evaporation after heat absorption in the cavity 14 to smoothly drift out of the structure and enter the steam generator to drive the normal operation of the steam generator. The function of the cavity 14 is to hold low-temperature water, so that the low-temperature water can surround the high-temperature flue gas, thereby making it easier for the low-temperature water to absorb the heat conducted by the heat conduction plate 10. The function of the sedimentation tank 15 is to collect the scale scraped off from the heat conduction plate 10, thereby facilitating the subsequent discharge of scale from the scale discharge pipe 5. The function of the water inlet pipe 3 is to introduce low-temperature water into the outer shell 1 for heating. The function of the drip nozzle 8 is to make the water introduced into the outer shell 1 more dispersed, and Furthermore, it can flow along the outer wall of the heat-conducting plate 10, making it easier for the introduced low-temperature water to absorb heat and evaporate, thereby accelerating the evaporation efficiency of the low-temperature water. The serpentine tube 11 can make the flow speed of the flue gas inside the outer shell 1 slower, which is more conducive to the dissipation of heat in the high-temperature flue gas. The sliding frame 9 can slide along the outer surface of the heat-conducting plate 10, so that the brush plate 18 on the inner wall of the sliding frame 9 can slide against the outer wall of the heat-conducting plate 10, thereby wiping away the scale condensed on the outer wall of the heat-conducting plate 10. At the same time, in conjunction with the low-temperature water flowing to the bottom of the heat-conducting plate 10, the scraped scale can be smoothly carried to the sedimentation tank 15 for collection, thereby facilitating the subsequent discharge of scale. The function of the exhaust pipe 6 is to discharge the flue gas that has released heat to the subsequent treatment equipment for treatment. The function of the scale discharge pipe 5 is to facilitate the discharge of scale from the outer shell 1.

[0025] Furthermore, electric cylinders 2 are fixedly installed on both sides of the top of the outer shell 1, and fixed plates 17 are fixedly connected to both sides of the sliding frame 9. The output end of the electric cylinder 2 is fixedly connected to the sliding frame 9 through the fixed plates 17. The function of the electric cylinder 2 is to provide power for the sliding frame 9 to slide along the heat-conducting plate 10, so that the sliding frame 9 can slide smoothly down along the outer wall of the heat-conducting plate 10, thereby cleaning the scale on the heat-conducting plate 10.

[0026] Furthermore, the sliding frame 9 is slidably connected to the heat-conducting plate 10 via the electric cylinder 2, and the brush plate 18 is slidably connected to the heat-conducting plate 10 via the sliding frame 9. The function of the brush plate 18 is to slide against the outer wall of the heat-conducting plate 10, thereby cleaning the scale generated on the heat-conducting plate 10.

[0027] Furthermore, the outlet of the drip nozzle 8 is located at the top of the heat-conducting plate 10, and the end of the inlet pipe 3 is connected to the outlet pipe 12, which is connected to the interior of the cavity 14. The function of the drip nozzle 8 is to allow low-temperature water to flow along the outer wall of the heat-conducting plate 10, so that the low-temperature water can be dispersed and contact the heat-conducting plate 10, which is more conducive to the heat absorption of the low-temperature water. It is also conducive to the low-temperature water to wash away the scale scraped off the heat-conducting plate 10, thus facilitating the timely cleaning of the scale on the heat-conducting plate 10.

[0028] Furthermore, the bottom end of the serpentine tube 11 is connected to the inside of the air inlet pipe 4, the top end of the serpentine tube 11 is connected to the inside of the air outlet pipe 6, and the bottom end of the air outlet pipe 6 is fixedly connected to the vertical rod 13, so that the high-temperature flue gas can flow and dissipate heat along the serpentine tube 11 in the outer shell 1, so that the heat can heat the low-temperature water in the cavity 14 after being dissipated through the heat-conducting plate 10, thereby realizing the evaporation of low-temperature water to form water vapor.

[0029] Furthermore, a groove 16 is provided at the bottom of the sedimentation tank 15. The groove 16 is connected to the scale discharge pipe 5. The function of the groove 16 is to allow the collected scale to flow into the scale discharge pipe 5 with the water flow, thereby facilitating the smooth discharge of scale from the outer shell 1.

[0030] Furthermore, a solenoid valve is installed at the inlet of the scale discharge pipe 5. The function of the solenoid valve is to control the opening and closing of the scale discharge pipe 5, thereby facilitating the timely discharge of scale from the sedimentation tank 15.

[0031] The usage method of this embodiment is as follows: When using this low-temperature connected incinerator power generation structure, first connect this structure to the flue pipe of the dust removal equipment corresponding to the incinerator, then connect the external power supply. Then, the flue gas will enter from the inlet pipe 4, and low-temperature water can be introduced into the water inlet pipe 3. At this time, the high-temperature flue gas will enter the serpentine pipe 11 along the inlet pipe 4, and then drift from the bottom end to the top end of the serpentine pipe 11. It will then enter the outlet pipe 6 along the top end of the serpentine pipe 11 and be discharged. During the drifting of the high-temperature flue gas, the high-temperature heat in the flue gas will be released through the heat-conducting plate 10. At the same time, the low-temperature water flowing out from the drip nozzle 8 at the bottom end of the water inlet pipe 3 will drip onto the top of the heat-conducting plate 10 and then flow along the outer wall of the heat-conducting plate 10 towards the sedimentation tank 15. This allows the low-temperature water to quickly absorb heat and evaporate during the flow, leaving only the remaining... Water enters the cavity 14 through the outlet pipe 12 and remains in the cavity 14 to continue absorbing heat until it turns into water vapor and is discharged from the water vapor outlet at the top of the outer shell 1. When it is necessary to clean the scale formed on the heat-conducting plate 10, the electric cylinder 2 can be activated to push the sliding frame 9 to slide up and down along the outer surface of the heat-conducting plate 10. The brush plate 18 on the inner wall of the sliding frame 9 wipes and cleans the scale on the heat-conducting plate 10, so that the scale on the heat-conducting plate 10 can be separated from the heat-conducting plate 10. Under the flushing of the low-temperature water flowing on the outer surface of the heat-conducting plate 10, the scale will fall into the sedimentation tank 15 and be collected. Finally, the solenoid valve at the scale discharge pipe 5 can be opened so that the scale collected in the sedimentation tank 15 can flow into the scale discharge pipe 5 along the groove 16 and be discharged out of the outer shell 1 through the scale discharge pipe 5.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
