Description

Technical Field

[0001] This utility model relates to the technical field of solid waste incineration devices, specifically to a solid waste incineration device with a waste heat utilization mechanism. Background Technology

[0002] Currently, with the rapid development of my country's economy, the prosperity of industrial and agricultural production, and the widespread availability of medical services, a large amount of solid waste, including medical waste, hazardous waste, domestic garbage, organic matter, and sludge, has been generated, causing serious environmental pollution. Waste incineration is a clean process for the harmless and volume-reduced treatment of solid and liquid waste.

[0003] Solid waste treatment mainly adopts three methods: incineration, landfill, and marine disposal. With the rapid development of incineration technology, solid waste incineration is becoming increasingly popular. Incineration is a comprehensive treatment process of high-temperature decomposition and deep oxidation of solid waste. Its advantage is that a large amount of harmful waste is decomposed into harmless substances.

[0004] A search revealed a utility model patent with publication number CN213272632U, which discloses a waste heat recovery and utilization device for solid waste incineration. The device includes a flue gas pipe for conveying the flue gas generated during solid waste incineration. The pipe's shell has several sets of through holes symmetrically arranged on opposite sides. A spherical heat exchanger is installed inside the pipe, allowing passage through the through holes. One end of the heat exchanger is connected to a feed pipe, and the other end is connected to a discharge pipe. Both the feed and discharge pipes are connected to the interior of the heat exchanger. The outer walls of the feed and discharge pipes are sealed to the inner walls of the two symmetrically arranged through holes. A stirring mechanism is installed inside the heat exchanger, containing a rotating shaft. One end of the shaft extends out of the corresponding feed pipe and is fitted with a turntable. A mounting seat for rotatable connection with the rotating shaft is installed inside the feed pipe. The stirring mechanism also includes several stirring rods. This utility model has a simple structure, facilitates the recovery and utilization of waste heat generated during solid waste incineration, and is easy to install and disassemble.

[0005] The aforementioned patent only achieves the recovery and utilization of waste heat inside the device by connecting both the feed pipe and the discharge pipe to the heat exchanger. However, solid waste needs to be pre-dried before combustion to prevent potential hazards such as deflagration during combustion due to moisture in the solid waste. Existing incineration devices cannot utilize the waste heat in the flue to heat and dry the burning solid waste. Furthermore, after the incineration device has been burning for a long time, workers need to discharge the waste residue generated inside. When the existing incineration device is stopped, the heat inside it dissipates quickly, resulting in a large amount of energy required to start the incineration again.

[0006] Therefore, it is necessary to propose a solid waste incineration device with a waste heat utilization mechanism to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a solid waste incineration device with a waste heat utilization mechanism. Through the cooperation of the internal parts of the incineration mechanism, the high-temperature flue gas generated by incineration can be used to heat and dry the solid waste in the discharge pipe. Through the cooperation of the internal parts of the exhaust mechanism, the high-temperature flue gas can be cooled and the toxic particles in the flue gas can be reduced. At the same time, the condensate formed by cooling can flow into the heat preservation water pipe to keep the temperature of the inner wall of the main body of the incineration device warm. This solves the problem that existing incineration devices cannot utilize the waste heat in the flue to heat and dry the burning solid waste. After the incineration device has been burning for a long time, the waste residue generated by the incineration needs to be discharged by the staff. However, after the existing incineration device is stopped, the heat inside it dissipates quickly, resulting in a large amount of energy required to start the incineration again.

A discharge chamber is provided above the combustion component and sleeved with the outer wall of the discharge pipe. A flue gas chamber is provided on one side of the discharge chamber. An insulated water pipe is provided inside the main body of the incineration device and sleeved on the inner wall of the main body of the incineration device.

[0010] Preferably, the smoke exhaust mechanism includes multiple smoke exhaust pipes, which are installed and fixed at the top of the main body of the incineration device and extend into the interior of the main body of the incineration device. An inlet trough is provided inside the main body of the incineration device, located at the top of the smoke exhaust chamber and the discharge pipe. Smoke exhaust troughs are provided at both ends of the inlet trough, located inside the main body of the incineration device. A baffle plate is provided at the bottom of the end of the smoke exhaust trough away from the inlet trough. Multiple drip tips are provided at the bottom of the baffle plate. A water baffle plate is provided below the baffle plate, installed and fixed inside the main body of the incineration device, and located above the insulated water pipe. A float plate is slidably connected inside the main body of the incineration device, located between the drip tips and the water baffle plate. A connecting column is connected to the bottom of the float plate, and a sealing cone is connected and fixed at the bottom of the connecting column, extending into the interior of the water baffle plate.

[0011] Preferably, the bottom of the unloading chamber is provided with an inclined baffle, the discharge pipe and the slag discharge plate are installed and fixed inside the main body of the incineration device at a certain inclined angle, and the surface of the supporting baffle is provided with a plurality of small slag discharge holes.

[0012] Preferably, the flue gas trough is V-shaped, and the inner wall of the flue gas trough is provided with a drainage trough that matches the condensate. The inner wall of the main body of the incineration device is provided with a water collection trough, which is located at the top and bottom of the water baffle plate. The diameter of the float plate is larger than the diameter of the sealing cone, and the outer wall of the float plate does not fit with the inner wall of the water collection trough.

[0013] Preferably, the inner wall of the main body of the incineration device is provided with a limiting groove that matches the float plate, the surface of the baffle plate is provided with a sealing groove that matches the sealing cone, the surface of the baffle plate is provided with a certain conical arc, and the water accumulation groove at the bottom of the baffle plate is connected to the heat preservation water pipe.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By starting the incineration assembly, the incineration assembly performs incineration operations inside the main body of the incineration unit. At the same time, the discharge pipe transports solid waste into the main body of the incineration unit. The solid waste is transported from the discharge pipe to the unloading chamber and falls into the main body of the incineration unit for incineration. The ash produced by incineration falls onto the ash discharge plate through the ash discharge holes on the support partition. The inclined ash discharge plate facilitates the ash falling to the side of the ash discharge door. At the same time, the high-temperature flue gas generated by combustion flows into the flue gas chamber. The high-temperature flue gas in the flue gas chamber wraps around the outer wall of the discharge pipe, which can complete the heating and drying operation of the solid waste in the discharge pipe. At the same time, the high-temperature flue gas diffuses inside the main body of the incineration unit, which can heat the heat insulation water pipe inside the main body of the incineration unit. When the operator shuts down the main body of the incineration unit and cleans the ash through the ash discharge door, the heat insulation water pipe keeps the inner wall of the main body of the incineration unit warm, which can reduce the energy required to restart the main body of the incineration unit and improve the secondary utilization of the waste heat from incineration.

[0016] 2. After the high-temperature flue gas flows into the exhaust chamber, it flows through the inlet trough to the outlet trough, where it gradually cools, producing condensate. This condensate then flows through a guide channel to the baffle plate, where it drips from the drip tip at the bottom, effectively reducing particulate impurities in the flue gas. This initial purification process is then completed. The purified flue gas is discharged from the main body of the incinerator through the exhaust pipe. The dripping water droplets accumulate in the water collection trough at the top of the baffle plate, and buoyancy causes the float plate to move. This movement of the float plate then moves the connecting column, connecting... The movement of the connecting column drives the sealing cone to move. As the sealing cone moves out of the baffle plate, it releases the seal on the sealing groove on the surface of the baffle plate. This allows the water in the water accumulation groove at the top of the baffle plate to flow through the sealing groove into the water accumulation groove at the bottom of the baffle plate and into the insulated water pipe. This replenishes the circulating water in the insulated water pipe. After the water in the water accumulation groove at the top of the baffle plate decreases, the floating plate, under its own weight, can use the connecting column to drive the sealing cone to seal the surface of the baffle plate. This improves the utilization rate of high-temperature flue gas in the main body of the incineration unit and completes the dust reduction treatment of particulate impurities in the flue gas, reducing the harm of flue gas emissions.

Through the mutual cooperation between the internal parts of the incineration mechanism 2, the high-temperature flue gas generated by incineration can be used to heat and dry the solid waste in the discharge pipe 201.

[0028] Refer to the instruction manual appendix Figure 1-5 The exhaust mechanism 3 includes multiple exhaust pipes 301, which are installed and fixed at the top of the main body 1 of the incineration device and extend into the interior of the main body 1.

Exhaust troughs 303 are provided at both ends of the inlet trough 302, located inside the main body 1 of the incineration device. A baffle plate 304 is provided at the bottom of the exhaust trough 303 away from the inlet trough 302. Multiple drip tips 305 are provided at the bottom of the baffle plate 304. A water-blocking plate 306 is provided below the baffle plate 304 and is fixed in place. Inside the main body 1 of the incineration device, and above the insulated water pipe 208, a float plate 307 is slidably connected inside the main body 1 of the incineration device, and is located between the drip tip 305 and the baffle plate 306. A connecting column 308 is connected to the bottom end of the float plate 307 and is fixed to the bottom end of the connecting column 308, and extends into the interior of the baffle plate 306. Through the mutual cooperation between the internal parts of the smoke exhaust mechanism 3, it is convenient to cool down the high-temperature flue gas and to reduce the dust of toxic particles in the flue gas. At the same time, the condensate formed by cooling can flow into the insulated water pipe 208 to keep the temperature of the inner wall of the main body 1 of the incineration device warm.

[0029] Refer to the instruction manual appendix Figure 1-5An inclined baffle is provided at the bottom of the unloading chamber 206. The discharge pipe 201 and the ash discharge plate 204 are installed and fixed inside the main body 1 of the incineration device at a certain inclined angle. Multiple small ash discharge holes are opened on the surface of the supporting baffle 205. Through the multiple small ash discharge holes opened on the surface of the supporting baffle 205, the ash from combustion can fall onto the ash discharge plate 204 through the supporting baffle 205.

[0030] Refer to the instruction manual appendix Figure 1-5 The exhaust trough 303 is V-shaped, and its inner wall is provided with a drainage channel matching the condensate. The inner wall of the incineration device body 1 is provided with a water collection trough, which is located at the top and bottom of the baffle plate 306. The diameter of the float plate 307 is larger than the diameter of the sealing cone 309, and the outer wall of the float plate 307 does not fit with the inner wall of the water collection trough. The exhaust trough 303 is V-shaped, and its inner wall is provided with a drainage channel matching the condensate. This allows the condensate to flow through the drainage channel to the side of the baffle plate 304 when the high-temperature flue gas flows and cools in the exhaust trough 303.

[0031] Refer to the instruction manual appendix Figure 1-5 The inner wall of the incineration device body 1 is provided with a limiting groove that matches the float 307. The surface of the baffle plate 306 is provided with a sealing groove that matches the sealing cone 309. The surface of the baffle plate 306 is provided with a certain conical arc. The water accumulation tank at the bottom of the baffle plate 306 is connected to the heat preservation water pipe 208. The water accumulation tank at the bottom of the baffle plate 306 is connected with the sealing groove that matches the sealing cone 309. The water accumulation tank at the top of the baffle plate 306 is provided with a certain conical arc, so that the water in the water accumulation tank above the baffle plate 306 can flow into the water accumulation tank at the bottom of the baffle plate 306 through the sealing groove, and then flow into the heat preservation water pipe 208 to replenish the circulating water in the heat preservation water pipe 208.

[0032] The working principle of this practical application is as follows:

[0033] Refer to the instruction manual appendix Figure 1-5By activating the incineration assembly 202, the incineration assembly 202 performs incineration operations inside the incineration unit body 1. Simultaneously, the discharge pipe 201 transports solid waste into the incineration unit body 1. The solid waste is transported from the discharge pipe 201 to the discharge chamber 206 and falls into the incineration unit body 1 for incineration. The ash produced by incineration falls onto the ash discharge plate 204 through the ash discharge holes on the support partition 205. The inclined ash discharge plate 204 facilitates the ash falling to the side of the ash discharge door 203. At the same time, the high-temperature flue gas generated by combustion flows into the flue gas exhaust chamber 2. Inside the exhaust chamber 207, the high-temperature flue gas wraps around the outer wall of the discharge pipe 201, thus completing the heating and drying operation of the solid waste inside the discharge pipe 201. At the same time, the high-temperature flue gas diffuses inside the main body 1 of the incineration device, which can heat the heat-insulating water pipe 208 inside the main body 1 of the incineration device. When the staff shuts down the main body 1 of the incineration device and cleans the ash through the ash discharge door 203, the heat-insulating water pipe 208 insulates the inner wall of the main body 1 of the incineration device, which can reduce the energy required to restart the main body 1 of the incineration device and improve the secondary utilization of the waste heat from incineration.

[0034] Refer to the instruction manual appendix Figure 1-5 After the high-temperature flue gas flows into the exhaust chamber 207, it flows through the inlet flue 302 into the exhaust flue 303, where it is gradually cooled, producing condensate. This condensate then flows through a guide channel in the exhaust flue 303 to the baffle plate 304, where it drips from the drip tip 305 at the bottom, thus reducing particulate impurities in the flue gas. This completes the initial purification of the flue gas. The purified flue gas is then discharged from the main body 1 of the incinerator through the exhaust pipe 301. The dripping water droplets accumulate in the water collection tank at the top of the baffle plate 306, and buoyancy causes the float plate 307 to move. The movement of the float plate 307 moves the connecting column 308, connecting... The movement of column 308 causes the sealing cone 309 to move, and the sealing cone 309 moves out of the interior of the baffle plate 306, thus releasing the seal on the sealing groove on the surface of the baffle plate 306. This allows the water in the water accumulation groove at the top of the baffle plate 306 to flow through the sealing groove into the water accumulation groove at the bottom of the baffle plate 306, and then into the insulated water pipe 208, thus completing the filling of the circulating water in the insulated water pipe 208. After the water in the water accumulation groove at the top of the baffle plate 306 is reduced, under the weight of the float plate 307 itself, the sealing cone 309 can be driven by the connecting column 308 to seal the surface of the baffle plate 306. This improves the utilization rate of high-temperature flue gas in the main body 1 of the incineration device and completes the dust reduction treatment of particulate impurities in the flue gas, reducing the harm of flue gas emissions.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
