Technical Field
[0001] This invention relates to the field of flue gas waste heat recovery technology, and in particular to a regenerative incinerator with a waste heat boiler structure. Background Technology
[0002] In recent years, waste heat recovery and utilization schemes that utilize flue gas waste heat to generate electricity and further improve the power generation efficiency of power plants have become increasingly popular. my country has abundant low-temperature waste heat resources and great potential for developing low-temperature waste heat recovery. However, it is necessary to select the appropriate equipment model according to each different waste heat source and design and optimize the recovery system. As a result, the research on industrial waste incineration equipment has developed rapidly, and the number of such equipment in enterprises is huge.

However, traditional waste heat recovery equipment for incinerator flue gas still has certain problems in use:

After long-term use, this not only affects the heat conduction effect of the heat exchange pipe and reduces the waste heat conversion rate, but also causes blockage inside the heat pipe, reducing the efficiency of flue gas waste heat recovery and utilization. Summary of the Invention

[0010] Furthermore, the outer surface of the connecting cylinder is fitted with the inner surface of the exhaust pipe, and a connecting ring is provided at the top of the connecting cylinder. Several sets of support blocks are fixedly connected at equal distances between the connecting ring and the connecting cylinder, and ventilation holes are formed between two adjacent sets of support blocks.
[0011] Furthermore, the bottom end of the connecting cylinder is closed, and a partition is fixedly connected inside the connecting cylinder.

A spring is provided on the outside of the movable pipe, and one end of the spring is fixedly connected to the movable pipe, while the other end is fixedly connected to the boiler body.
[0013] Furthermore, the heat conduction mechanism includes a heat conduction frame one, a heat conduction frame two, and several sets of heat conduction pipes; the top of the inner surface of the boiler body is fixedly connected to the heat conduction frame one, one end of the flue pipe penetrates into the interior of the boiler body and is fixedly connected to the heat conduction frame two, several sets of flexible hoses are fixedly connected in an annular shape at equal intervals on the upper outer surface of the heat conduction frame two and the lower outer surface of the heat conduction frame one, and a heat conduction pipe is fixedly connected between two corresponding sets of flexible hoses, and a movable pipe penetrates into the interior of the heat conduction frame one and is movably connected to it.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0017] 1. In this invention, by setting the air pressure between the connecting cylinder and the exhaust pipe to be variable, and combined with the elastic force of the spring, the connecting cylinder driving the fixed rod repeatedly drives the connecting plate to move up and down with the connecting cylinder. Therefore, the spiral rod drives the rotating rod to rotate repeatedly under the drive of the connecting plate. During the rotation of the rotating rod, the scraper scrapes the inner surface of the heat-conducting pipe, causing the particles attached to the inner wall of the heat-conducting pipe to fall into the interior of the smoke outlet pipe and be discharged. This avoids the phenomenon that the heat conduction efficiency is reduced due to the particles adhering to the inner wall of the heat-conducting pipe and thickening it. At the same time, it avoids the heat-conducting pipe from becoming blocked and affecting the flow of flue gas.
[0018] 2. In this invention, by setting up a heat conduction mechanism and a cleaning mechanism to cooperate with each other, while scraping the inner wall of the heat conduction tube with a scraper, the width of the scraper is located between the inner diameter of the heat conduction tube and half of the inner diameter of the heat conduction tube. This allows the scraper to push the heat conduction tube to swing around inside the boiler body during rotation, which enables the liquid and flue gas inside the boiler body to exchange heat fully and improve the heating efficiency of the boiler body.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example 1: As Figure 1 and Figure 2 As shown, the present invention proposes a regenerative incinerator with a waste heat boiler structure, including a base 1, an incinerator body 2 and a boiler body 3 are provided on the upper outer surface of the base 1, a feed inlet is provided on one side of the incinerator body 2, and a sealing door 4 is hinged to the outside of the feed inlet, and a flue pipe 5 is provided on the side of the incinerator body 2 near the boiler body 3.
[0030] The material is fed into the incinerator body 2 through the feed inlet for combustion. The flue gas generated inside the incinerator body 2 during the combustion process enters the boiler body 3 through the exhaust pipe 5 and exchanges heat with the liquid inside the boiler body 3. The end of the exhaust pipe 5 away from the incinerator body 2 is connected to the boiler body 3. An observation window 6 is provided on one side of the boiler body 3, and an inlet pipe 10 and an outlet pipe 11 are respectively provided on the outer surface of one side of the boiler body 3 near the upper and lower ends.
[0031] A flue pipe 12 is provided at the bottom of the boiler body 3. The flue gas is discharged through the flue pipe 12 after heat exchange, thereby exchanging heat with the liquid inside the boiler body 3 to realize the recovery and utilization of the heat of the flue gas. One end of the flue pipe 12 extends into the interior of the boiler body 3 and is connected to the boiler body 3 by a heat conduction mechanism 8. A collection mechanism 7 for filtering particulate matter in the flue gas is provided between the heat conduction mechanism 8 and the flue pipe 5. This can initially block particulate matter in the flue gas and reduce the amount of particulate matter entering the heat conduction pipe 803. A cleaning mechanism 9 for preventing the heat conduction mechanism 8 from becoming clogged is provided between the collection mechanism 7 and the heat conduction mechanism 8.
[0032] Example 2: Figure 1-6 As shown, the difference between this embodiment and embodiment 1 is that the collecting mechanism 7 includes a movable hole opened on the upper outer surface of the boiler body 3, and a movable pipe 701 is movably connected inside the movable hole. One end of the flue pipe 5 passes through the interior of the movable pipe 701 and is movably connected to it. A sealing ring is provided between the movable pipe 701 and the flue pipe 5 to prevent the flue gas from escaping.
[0033] The movable tube 701 is provided with a connecting cylinder 702 inside, and a connecting block 703 is fixedly connected between the connecting cylinder 702 and the movable tube 701. The bottom end and one end of the connecting cylinder 702 pass through the interior of the flue pipe 5 and are movably connected thereto. The flue gas generated inside the incinerator body 2 during the incineration process enters the interior of the connecting cylinder 702 through the flue pipe 5.
[0034] The outer surface of the connecting cylinder 702 is in contact with the inner surface of the flue pipe 5, and a connecting ring 704 is provided at the top of the connecting cylinder 702. Several sets of support blocks 705 are fixedly connected at equal distances between the connecting ring 704 and the connecting cylinder 702. A vent hole 706 is formed between two adjacent sets of support blocks 705. As the flue gas volume increases, the air pressure between the flue pipe 5 and the connecting cylinder 702 increases. The connecting cylinder 702 drives the movable pipe 701 to move into the interior of the boiler body 3 until the support block 705 is exposed outside the flue pipe 5.
[0035] The bottom end of the connecting cylinder 702 is closed, and a partition 707 is fixedly connected inside the connecting cylinder 702. Several sets of air guide holes 710 are evenly spaced on the outer surface of the partition 707, and the inner diameter of the air guide holes 710 decreases from top to bottom. The flue gas passes through the vent 706 and the movable tube 701 and enters the interior of the second heat-conducting frame 802. The flue gas located below the partition 707 also floats up to the top of the partition 707 and enters the interior of the second heat-conducting frame 802 through the air guide holes 710. The air guide holes 710 can block the particulate matter in the flue gas that rises again, reducing the amount of particulate matter entering the interior of the heat-conducting tube 803.
[0036] A discharge pipe 708 is fixedly connected to one side of the outer surface of the connecting cylinder 702, and one end of the discharge pipe 708 extends through to the outside of the movable pipe 701 and is fixedly connected thereto. The discharge pipe 706 periodically cleans the particles inside the connecting cylinder. A control valve is installed on the outer surface of the discharge pipe 708 at a position outside the movable pipe 701. A spring 709 is installed on the outside of the movable pipe 701, and one end of the spring 709 is fixedly connected to the movable pipe 701, and the other end is fixedly connected to the boiler body 3.
[0037] Example 3: Figure 2 and Figure 3 As shown, the difference between this embodiment and Embodiments 1 and 2 is that the heat conduction mechanism 8 includes a heat conduction frame 801, a heat conduction frame 802, and several sets of heat conduction pipes 803; the top of the inner surface of the boiler body 3 is fixedly connected to the heat conduction frame 801, and the flue gas enters the interior of the heat conduction frame 801 through the air guide hole 710.
[0038] One end of the flue pipe 12 extends into the interior of the boiler body 3 and is fixedly connected to a second heat-conducting frame 802. Several sets of flexible hoses 804 are fixedly connected in an annular shape at equal intervals to the upper outer surface of the second heat-conducting frame 802 and the lower outer surface of the first heat-conducting frame 801. A heat-conducting pipe 803 is fixedly connected between two corresponding sets of flexible hoses 804. A movable pipe 701 extends into the interior of the first heat-conducting frame 801 and is movably connected to it. The flue gas disperses into the interior of each heat-conducting pipe 803 and fully exchanges heat with the liquid inside the boiler.
[0039] Example 4: Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the difference between this embodiment and Embodiments 1, 2, and 3 is that the cleaning mechanism 9 includes a fixed rod 901, a connecting plate 902, and a spiral rod 903. During the process of flue gas entering the heat-conducting frame 801 through the air guide hole 710, the air pressure between the exhaust pipe 5 and the connecting cylinder 702 decreases. Under the action of the spring 709, the movable pipe 701 drives the connecting cylinder 702 to move upward and return to its original state.
[0040] As the flue gas gathers between the exhaust pipe 5 and the connecting cylinder 702, the movable pipe 701 and the connecting cylinder 702 move down again. A fixed rod 901 is fixedly connected to the lower outer surface of the connecting cylinder 702, and the bottom end of the fixed rod 901 penetrates into the interior of the second heat-conducting frame 802 and is fixedly connected to several sets of connecting plates 902. A spiral hole is opened on the outer surface of the connecting plate 902 at the position corresponding to the heat-conducting pipe 803, and a spiral rod 903 is spirally connected inside the spiral hole. The top end of the spiral rod 903 is rotatably connected to the first heat-conducting frame 801. The fixed rod 901 repeatedly drives the connecting plate 902 to move up and down with the connecting cylinder 702. Therefore, the spiral rod 903 drives the rotating rod 904 to rotate repeatedly under the drive of the connecting plate 902.
[0041] One end of the spiral rod 903 is fixedly connected to a rotating rod 904, and the bottom end of the rotating rod 904 penetrates into the corresponding heat pipe 803. A scraper 905 is fixedly connected to the outer surface of the rotating rod 904 at the position corresponding to the heat pipe 803. As the scraper 905 rotates with the rotating rod 904, it scrapes the inner surface of the heat pipe 803, causing the particles attached to the inner wall of the heat pipe 803 to fall into the smoke outlet pipe 12 and be discharged.
[0042] Furthermore, the width of the scraper 905 is located between the inner diameter of the heat pipe 803 and half of the inner diameter of the heat pipe 803. The outer surface of one side of the scraper 905 is in contact with the inner surface of the heat pipe 803. Therefore, during the rotation of the scraper 905, the scraper 905 pushes the heat pipe 803 to swing around inside the boiler body 3, thereby enabling the liquid and flue gas inside the boiler body 3 to exchange heat fully and improve the heating efficiency of the boiler body 3.
[0043] The working process and principle of this invention are as follows:
[0044] Step 1: The material is fed into the incinerator body 2 through the feed port for combustion. The flue gas generated inside the incinerator body 2 during the combustion process enters the interior of the connecting cylinder 702 through the exhaust pipe 5 and enters the lower part of the baffle 707 through the air guide hole 710.
[0045] Step 2: As the flue gas volume increases, the air pressure between the flue pipe 5 and the connecting cylinder 702 increases. The connecting cylinder 702 drives the movable pipe 701 to move into the interior of the boiler body 3 until the support block 705 is exposed outside the flue pipe 5. At this time, the flue gas passes through the vent 706 and the movable pipe 701 and enters the interior of the heat-conducting frame 802. The flue gas located below the baffle 707 also floats above the baffle 707 again and enters the interior of the heat-conducting frame 802 through the air guide hole 710. The air guide hole 710 can block the particulate matter in the flue gas that rises again, reducing the amount of particulate matter entering the interior of the heat-conducting pipe 803.
[0046] Step 3: The flue gas enters the heat conduction frame 801 through the heat conduction pipe 803 and is finally discharged through the flue gas outlet pipe 12, thereby exchanging heat with the liquid inside the boiler body 3 to realize the recovery and utilization of flue gas heat.
[0047] Step 4: As the flue gas enters the heat-conducting frame 801 through the air guide hole 710, the air pressure between the exhaust pipe 5 and the connecting cylinder 702 decreases. Under the action of the spring 709, the movable pipe 701 drives the connecting cylinder 702 to move upward and return to its original state. As the flue gas accumulates between the exhaust pipe 5 and the connecting cylinder 702, the movable pipe 701 and the connecting cylinder 702 move downward again. The fixed rod 901 repeatedly drives the connecting plate 902 to move up and down with the connecting cylinder 702. Therefore, the spiral rod 903 drives the rotating rod 904 to rotate repeatedly under the drive of the connecting plate 902. As the scraper 905 rotates with the rotating rod 904, it scrapes the inner surface of the heat-conducting pipe 803, causing the particles attached to the inner wall of the heat-conducting pipe 803 to fall into the interior of the exhaust pipe 12 and be discharged.
[0048] Step 5: Since the width of the scraper 905 is between the inner diameter of the heat pipe 803 and half of the inner diameter of the heat pipe 803, during the rotation of the scraper 905, the scraper 905 pushes the heat pipe 803 to swing around inside the boiler body 3, which can make the liquid and flue gas inside the boiler body 3 fully exchange heat and improve the heating efficiency of the boiler body 3.
[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
