Description

Technical Field

[0001] The present application relates to the technical field of waste incineration treatment, and in particular to an intelligent heat storage incinerator. Background Art

[0002] An incinerator is an environmental protection equipment used for high-temperature incineration of waste gas, waste liquid, solid waste, medical waste, domestic waste, animal carcasses, etc. It uses coal, oil, gas and other fuels for combustion, and achieves the purpose of disinfection and reduction of waste volume through high-temperature incineration and carbonization.

[0003] A large amount of waste gas will be emitted during the operation of the incinerator. The temperature of this waste gas is relatively high. If it is discharged directly, it will cause a huge waste of heat, which is obviously insufficient. Summary of the invention

[0004] In order to recycle and utilize the heat in the exhaust gas, the present application provides an intelligent heat storage incinerator.

[0005] The intelligent regenerative incinerator provided in this application adopts the following technical solution:

[0006] An intelligent heat storage incinerator comprises an inner furnace body which is hollow inside and used for incineration, the inner cavity of the inner furnace body is connected to a smoke exhaust pipe, the outer periphery of the inner furnace body is surrounded by an outer furnace body which is hollow inside and closed, the smoke exhaust pipe passes through the outer furnace body to the outside, the smoke exhaust pipe is arranged in a serpentine shape inside the outer furnace body, the inner cavity of the outer furnace body is connected to a water supply pipe and a drain pipe, and the water supply pipe and the drain pipe are both provided with a first solenoid valve electrically connected to a control system.

[0007] By adopting the above technical solution, water enters the outer furnace body from the water supply pipe and then flows out from the drain pipe. During the operation of the inner furnace body, the exhaust gas is discharged from the exhaust pipe. When the exhaust gas flows through the exhaust pipe, the heat will be absorbed by the water in the outer furnace body, thereby realizing the recovery and storage of waste heat of the exhaust gas and reducing heat loss.

[0008] Optionally, a plurality of insulated high-pressure gas tanks are arranged inside the outer furnace body, a booster air pump electrically connected to the control system is arranged outside the outer furnace body, the air inlet end of the booster air pump is connected to the inner cavity of the outer furnace body, and the air outlet end is connected to each insulated high-pressure gas tank, a second solenoid valve electrically connected to the control system is arranged between the booster air pump and the insulated high-pressure gas tank, an exhaust valve electrically connected to the control system is also arranged on the insulated high-pressure gas tank, and a heat control component for controlling heat flow is arranged between the outer furnace body and the inner furnace body.

[0009] By adopting the above technical solution, during the heat recovery process, part of the water absorbs heat and turns into water vapor, and the booster pump sends the water vapor into the insulated high-pressure gas tank for compression and storage. Before the next incineration operation of the incinerator, the control system opens the heat control component and the exhaust valve, and the water vapor in the insulated high-pressure gas tank returns to the outer furnace body. At this time, the heat of the water vapor returns to the inner furnace body through the heat control component, thereby absorbing and preheating the inner furnace body, which is conducive to the inner furnace body quickly reaching the combustion state.

[0010] Optionally, the heat control component includes a plurality of heat-conducting rods inserted between the inner and outer walls of the inner furnace body near the top, an installation groove is opened between the inner and outer walls of the outer furnace body at a position relative to the heat-conducting rods, and an insulation frame is arranged in the installation groove, the insulation frame is arranged with a plurality of vacuum insulation panels arranged in a row, a tension spring is arranged between two adjacent vacuum insulation panels, the vacuum insulation panel at one end is fixed to the insulation frame, and the remaining vacuum insulation panels are slidably arranged in the insulation frame, and a pull frame is arranged on the vacuum insulation panel at the other end, and a threaded pull rod that passes through to the outside and is threadedly connected to the outer furnace body is rotatably arranged on the pull frame.

[0011] By adopting the above technical solution, during the heat storage process of the outer furnace body, two adjacent vacuum insulation panels are closely attached to achieve heat insulation transfer. When the inner furnace body needs to be preheated, the worker manually turns the threaded pull rod, and the threaded pull rod pulls the vacuum insulation panel to slide on the insulation frame through the pull frame, and a gap is generated between the two adjacent vacuum insulation panels, and the tension spring is stretched. At this time, the heat in the outer furnace body can pass through the gap to the heat conducting rod, and then be transferred to the inner furnace body by the heat conducting rod.

[0012] Optionally, the bottoms of the various insulated high-pressure gas tanks are also commonly connected to a drain pipe, which passes out of the outer furnace body and is provided with a drain valve.

[0013] By adopting the above technical solution, the temperature will gradually decrease during the process of storing water vapor in the insulated high-pressure gas cylinder, and part of the water vapor may return to liquid water. Therefore, before starting each incineration work, the drain valve is opened in advance to discharge the moisture, so as to increase the storage capacity of water vapor in the insulated high-pressure gas cylinder.

[0014] Optionally, a water supply pipe extending to near the bottom of the outer furnace body is arranged on the vacuum insulation panel, and a water supply pipe is passed through the heat conductive rod. One end of the water supply pipe located in the inner furnace body is connected to a nozzle, and the other end extends to be close to the vacuum insulation panel and is used to communicate with the water supply pipe. A sealing component for sealing the water supply pipe is also provided in the insulation frame.

[0015] By adopting the above technical solution, during the heat storage process of the outer furnace body, the plugging component is in a plugging state for the water supply pipe. When the plugging component is activated, the vacuum insulation panel will drive the water supply pipe to be connected with the corresponding water delivery pipe, so that when the water vapor in the heat-insulating high-pressure gas tank is released into the outer furnace body again, the water at the bottom of the outer furnace body flows back to the water delivery pipe through the water supply pipe, and then is sprayed out by the nozzle, thereby humidifying the ash produced by the incineration, reducing the adverse effects caused by the flying of the ash during the removal process.

[0016] Optionally, the sealing assembly includes a bracket hinged in an insulation frame, a plurality of plugs are arranged on the bracket, each plug corresponds to a water supply pipe, a telescopic cylinder electrically connected to a control system is arranged on the top of the outer furnace body, a piston rod of the telescopic cylinder extends into the insulation frame and is hinged with a first connecting rod, and a second connecting rod is hinged between the first connecting rod and the bracket.

[0017] By adopting the above technical solution, under the action of the control system, the piston rod of the telescopic cylinder performs telescopic movement, so that the first connecting rod drives the bracket to rotate through the second connecting rod, and the bracket can drive the plug to rotate, thereby realizing the sealing and conducting effect of the plug on the water supply pipe.

[0018] Optionally, a sealing cushion is arranged at the contact point between the plug and the water supply pipe.

[0019] By adopting the above technical solution, the sealing cushion improves the sealing effect between the plug and the water supply pipe, and reduces the possibility of heat leakage in the outer furnace body.

[0020] Optionally, a heat insulating pad is arranged between the telescopic cylinder and the outer furnace body.

[0021] By adopting the above technical solution, the heat insulating pad has a strong heat insulating performance, which can reduce the possibility of heat being transferred from the outer furnace body to the telescopic cylinder, thereby improving the service stability and life of the telescopic cylinder.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Water enters the outer furnace body from the water supply pipe and then flows out from the drain pipe. During the operation of the inner furnace body, the exhaust gas is discharged from the exhaust pipe. When the exhaust gas flows through the exhaust pipe, the heat will be absorbed by the water in the outer furnace body, thereby realizing the recovery and storage of waste heat from the exhaust gas and reducing heat loss;

[0024] 2. During the heat recovery process, part of the water absorbs heat and turns into water vapor. The booster pump sends the water vapor into the insulated high-pressure gas tank for compression and storage. Before the next incineration operation of the incinerator, the control system opens the heat control component and the second solenoid valve, and the water vapor in the insulated high-pressure gas tank returns to the outer furnace body. At this time, the heat of the water vapor returns to the inner furnace body through the heat control component, thereby absorbing and preheating the inner furnace body, which is conducive to the inner furnace body reaching the combustion state quickly;

[0025] 3. During the heat storage process of the outer furnace body, two adjacent vacuum insulation panels are close together to achieve heat insulation transfer. When the inner furnace body needs to be preheated, the worker manually turns the threaded pull rod, and the threaded pull rod pulls the vacuum insulation panel to slide on the insulation frame through the pull frame, and a gap is generated between the two adjacent vacuum insulation panels. The tension spring is stretched, and the heat in the outer furnace body can pass through the gap to the heat conducting rod, and then be transferred to the inner furnace body by the heat conducting rod;

[0026] 4. During the heat storage process of the outer furnace body, the plugging component is in a plugging state for the water supply pipe. When the plugging component is activated, the vacuum insulation panel will drive the water supply pipe to be connected with the corresponding water delivery pipe, so that when the water vapor in the heat-insulating high-pressure gas tank is released into the outer furnace body again, the water at the bottom of the outer furnace body flows back to the water delivery pipe through the water supply pipe, and then sprayed out by the nozzle, thereby humidifying the ash produced by incineration, reducing the adverse effects caused by the flying of ash during the process of removing ash.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses an intelligent heat storage incinerator.

[0035] Reference Figure 1 and Figure 2 The intelligent regenerative incinerator includes an inner furnace body 1 which is hollow inside and used for incineration, and an outer furnace body 3 which is hollow inside and closed is formed around the inner furnace body 1. The inner cavity of the inner furnace body 1 is connected with a smoke exhaust pipe 2, which passes through the outer furnace body 3 and extends to the outside. The pipe body of the smoke exhaust pipe 2 located in the outer furnace body 3 is arranged in a serpentine shape.

[0036] Reference Figure 1 and Figure 2 The inner cavity of the outer furnace body 3 is connected with a water supply pipe 4 and a drainage pipe 5, and the water supply pipe 4 and the drainage pipe 5 are both provided with a first solenoid valve 6 electrically connected to the control system. The water supply pipe 4 and the drainage pipe 5 are connected to the external water circulation system.

[0037] Reference Figure 1 and Figure 2 During the operation of the incinerator, the exhaust gas is discharged to the outside through the exhaust pipe 2. Cold water flows into the outer furnace body 3 from the water supply pipe 4, and then absorbs the heat of the exhaust gas through the exhaust pipe 2, and then is discharged from the drain pipe 5, thereby recovering and reusing the heat.

[0038] Reference Figure 1 and Figure 2 A plurality of heat-insulating high-pressure gas cylinders 7 are arranged in the outer furnace body 3, and a booster air pump 8 electrically connected to the control system is provided at the top suppository of the inner furnace body 1. The air inlet end of the booster air pump 8 is connected to the inner cavity of the outer furnace body 3, and the air outlet end is connected to each heat-insulating high-pressure gas cylinder 7.

[0039] Reference Figure 1 and Figure 2A second solenoid valve 9 electrically connected to the control system is arranged between the booster air pump 8 and the insulated high-pressure gas tank 7. An exhaust valve 13 electrically connected to the control system is also threadedly connected to the insulated high-pressure gas tank 7. A pressure gauge (not shown in the figure) extending to the outside of the outer furnace body 3 is also threadedly connected to the insulated high-pressure gas tank 7.

[0040] Reference Figure 1 and Figure 2 In the process of heat recovery and reuse, part of the water will absorb heat and form water vapor. The booster air pump 8 sends the water vapor into the insulated high-pressure gas tank 7 for compression and insulation. The workers can detect the air pressure in the insulated high-pressure gas tank 7 in real time through the barometer.

[0041] Before the incinerator is used again, the worker opens the exhaust valve 13 through the control system to release the water vapor in the heat-insulating high-pressure gas tank 7. The water vapor returns to the outer furnace body 3 for liquefaction, and the released heat returns to the inner furnace body 1 for preheating, which is conducive to the inner furnace body 1 to quickly reach a combustion state.

[0042] Reference Figure 2 The bottom of each insulated high-pressure gas tank 7 is also connected to a drain pipe 16, which passes through the outer furnace body 3 and is provided with a drain valve 17. When the gas pressure in the insulated high-pressure gas tank 7 is too high, the worker opens the drain valve 17 to release part of the water vapor, reducing the possibility of the insulated high-pressure gas tank 7 exploding due to excessive gas pressure.

[0043] In addition, during the insulation process of the insulated high-pressure gas tank 7, some heat will inevitably be lost, and some water vapor will liquefy into liquid water. Therefore, the drain valve 17 and the drain pipe 16 cooperate to discharge this part of the water, thereby increasing the storage capacity of the insulated high-pressure gas tank 7 for water vapor.

[0044] Reference Figure 3 and Figure 4 A heat control component for controlling heat flow is arranged between the outer furnace body 3 and the inner furnace body 1. The heat control component includes a plurality of heat conducting rods 10 fixedly penetrated between the inner and outer walls of the inner furnace body 1 and close to the top. The heat conducting rods 10 are made of metal material and have good thermal conductivity.

[0045] Reference Figure 3 and Figure 4 An installation groove 31 is opened between the inner and outer walls of the outer furnace body 3 at a position relative to the heat conducting rod 10, and an insulation frame 11 made of insulation material is embedded in the installation groove 31. A plurality of vacuum insulation panels 12 arranged in a row are arranged in the insulation frame 11. Two adjacent vacuum insulation panels 12 are plugged together and a tension spring (not shown in the figure) is hung between them.

[0046] Reference Figure 3 and Figure 4The vacuum insulation panel 12 at one end is fixed to the insulation frame 11, and the other vacuum insulation panels 12 are slidably arranged in the insulation frame 11, and a pull frame 14 is fixed on the vacuum insulation panel 12 at the other end, and a threaded pull rod 15 is rotatably arranged on the pull frame 14, which passes through the outside and is threadedly connected to the outer furnace body 3.

[0047] Reference Figure 3 and Figure 4 When the incinerator is in operation, the vacuum insulation panels 12 arranged in a row are assembled into a whole panel and the insulation frame 11 is completely blocked, so that heat is not transferred between the inner furnace body 1 and the outer furnace body 3.

[0048] Reference Figure 3 and Figure 4 Before the incinerator is used again, the worker manually twists the threaded pull rod 15, and the threaded pull rod 15 applies tension to each vacuum insulation panel 12 through the pull frame 14, so that the two adjacent vacuum insulation panels 12 are pulled apart, so that the heat released by the water vapor in the outer furnace body 3 is transferred from between the two adjacent vacuum insulation panels 12 to the heat conducting rod 10, and then transferred to the inner furnace body 1, thereby preheating the inner furnace body 1.

[0049] Reference Figure 3 , Figure 4 and Figure 5 A water supply pipe 18 extending to the bottom of the outer furnace body 3 is fixedly penetrated on the vacuum insulation panel 12, and a water supply pipe 19 is coaxially fixedly penetrated on the heat conducting rod 10. One end of the water supply pipe 19 located in the inner furnace body 1 is connected to a nozzle 20, and the other end extends to be close to the vacuum insulation panel 12 and is used to communicate with the water supply pipe 18. A sealing component for sealing the water supply pipe 18 is also provided in the insulation frame 11.

[0050] Reference Figure 3 , Figure 4 and Figure 5 The sealing assembly includes a bracket 21 hinged in the insulation frame 11, and a plurality of plugs 22 are threadedly connected to the bracket 21. Each plug 22 corresponds to a water supply pipe 18. The plug 22 is made of insulation material, and a sealing pad 26 is bonded to the contact between the plug 22 and the water supply pipe 18.

[0051] A telescopic cylinder 23 electrically connected to the control system is bolted to the top of the outer furnace body 3 . The piston rod of the telescopic cylinder 23 extends into the heat insulation frame 11 and is hinged to a first connecting rod 24 . A second connecting rod 25 is hinged between the first connecting rod 24 and the bracket 21 .

[0052] Reference Figure 3 , Figure 4 and Figure 5During the heat storage process, the water supply pipe 18 is in a closed state, and the plug 22 is plugged into the end of the water supply pipe 18. When the outer furnace body 3 transfers heat to the inner furnace body 1 to achieve preheating, the piston rod of the telescopic cylinder 23 extends, so that the plug 22 releases the blocking effect on the top of the water supply pipe 18 through the rotation of the first connecting rod 24, the second pull rod and the bracket 21.

[0053] Afterwards, when the vacuum insulation panel 12 moves, it can drive the water supply pipe 18 to connect with the corresponding water delivery pipe 19. When the insulated high-pressure gas tank 7 releases water vapor, the water vapor can press the water in the outer furnace body 3 into the water supply pipe 18, and then flow back to the water delivery pipe 19 and spray out from the nozzle 20 into the inner furnace body 1, thereby spraying and humidifying the ash in the inner furnace body 1, reducing the adverse effects caused by the flying of ash during the process of removing the ash.

[0054] Reference Figure 4 An insulating pad (not shown in the figure) is provided between the telescopic cylinder 23 and the outer furnace body 3. The insulating pad has strong thermal insulation performance, which can reduce the possibility of heat being transferred from the outer furnace body 3 to the telescopic cylinder 23, thereby improving the service stability and life of the telescopic cylinder 23.

[0055] The implementation principle of an intelligent regenerative incinerator in the embodiment of the present application is:

[0056] During the operation of the incinerator, the exhaust gas is discharged to the outside through the exhaust pipe 2. Cold water flows into the outer furnace body 3 from the water supply pipe 4, then absorbs the heat of the exhaust gas through the exhaust pipe 2, and then is discharged from the drain pipe 5, thereby recovering and reusing the heat. During the heat recovery and reuse process, part of the water will absorb heat and form water vapor, and the booster air pump 8 will send the water vapor into the insulated high-pressure gas tank 7 for compression and insulation.

[0057] When the outer furnace body 3 transfers heat to the inner furnace body 1 to achieve preheating, the piston rod of the telescopic cylinder 23 extends, thereby releasing the plug 22 from blocking the top of the water supply pipe 18 through the rotation of the first connecting rod 24, the second pull rod and the bracket 21.

[0058] The worker manually twists the threaded pull rod 15, and the threaded pull rod 15 applies tension to each vacuum insulation panel 12 through the pull frame 14. The two adjacent vacuum insulation panels 12 are pulled apart, and the vacuum insulation panel 12 drives the water supply pipe 18 to move to communicate with the corresponding water supply pipe 19. The heat released by the water vapor in the external furnace body 3 is transferred from between the two adjacent vacuum insulation panels 12 to the heat conducting rod 10, and then transferred to the inner furnace body 1, thereby preheating the inner furnace body 1.

[0059] Moreover, the water vapor can press the water in the outer furnace body 3 into the water supply pipe 18, and then flow back to the water delivery pipe 19 and be sprayed from the nozzle 20 into the inner furnace body 1, thereby spraying and humidifying the ash in the inner furnace body 1, reducing the adverse effects caused by the flying of ash during the process of removing the ash.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
