Description

Technical Field

[0001] This utility model belongs to the field of incinerator technology, and specifically relates to a heat recovery device after incineration. Background Technology

[0002] Existing industrial incinerators generate large amounts of high-temperature exhaust gas when processing waste or other materials. This exhaust gas not only contains significant amounts of heat energy but may also contain harmful substances and pollutants. Conventional incinerators described in existing patent literature typically release the exhaust gas directly into the atmosphere, which presents several problems:

[0003] 1. Energy waste: The heat energy in the exhaust gas is not effectively utilized, resulting in energy waste.

[0004] 2. High operating costs: Due to the lack of heat recovery and utilization, the operating costs of the incinerator are high.

[0005] To address the aforementioned problems, a post-incineration heat recovery device has been invented, which can effectively recover the heat energy from the exhaust gas. Summary of the Invention

[0006] To address the above-mentioned technical problems, this invention proposes a heat recovery device after incineration. Through the design of a thermal oil furnace and a heat exchanger, the heat energy in the exhaust gas of the incinerator is effectively recovered. This design not only reduces energy waste but also lowers the operating cost of the incinerator. Compared with traditional incinerators that directly emit exhaust gas, this system achieves efficient utilization of heat energy and improves energy efficiency.

[0007] The technical solution of this utility model is:

[0008] This utility model proposes a heat recovery device after incineration, including an incinerator, a thermal oil furnace connected to the incinerator, a heat exchanger connected to the thermal oil furnace, a blower connected to the heat exchanger, and the air outlet of the blower connected to the incinerator.

[0011] There are two symmetrical baffles to block the air outlet. Each baffle is connected to a movable plate on one side and the two baffles are located inside the air outlet.

[0015] There are two movable rods, which are symmetrically arranged. The two symmetrical movable rods are located on both sides of the cam and cooperate with the outer wall of the cam. The outer wall of the movable rod is connected to a limit ring. The end of the movable rod away from the cam is connected to the movable plate.

[0016] There are two fixed plates, which are symmetrically arranged. The fixed plates are fixedly connected to the inside of the air outlet, and the moving rod is slidably connected to the fixed plates.

[0017] There are two springs, which are symmetrical and are connected to the moving rod. The springs are located between the fixed plate and the limiting ring.

[0028] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.

[0029] Example 1:

[0030] like Figures 1-3 As shown, this utility model provides a heat recovery device after incineration, including an incinerator, a thermal oil furnace connected to the incinerator, a heat exchanger connected to the thermal oil furnace, the heat exchanger being connected to a blower 1, and the air outlet 10 of the blower 1 being connected to the incinerator.

[0031] In use, the exhaust gas produced by the incinerator undergoes heat exchange through a thermal oil heater. The thermal oil heater transfers the heat to the heat exchanger, which uses this heat to heat fluids such as water or air, providing the thermal energy required for industrial processes.

[0032] Meanwhile, the blower 1 supplies an appropriate amount of air to the incinerator through the air outlet 10 to support the combustion process.

[0033] An adjustment unit is provided on the air outlet 10 of the blower 1, which is used to adjust the opening size of the air outlet 10.

[0034] Preferably, the adjustment unit includes:

[0035] There are two shields 2, which are symmetrically arranged. The shields 2 are used to shield the air outlet 10. Each shield 2 is connected to a movable plate 20 on one side. The two shields 2 are located inside the air outlet 10.

[0036] The adjustment components are provided in two sets, with the two sets of adjustment components located on both sides of the baffle plate 2 respectively;

[0037] Each set of adjustment components includes:

[0038] Cam 3 is rotatably connected to the inside of air outlet 10, and both ends of cam 3 are provided with protrusions.

[0039] There are two movable rods 30, which are symmetrically arranged. The two symmetrical movable rods 30 are located on both sides of the cam 3 and cooperate with the outer wall of the cam 3. The outer wall of the movable rod 30 is connected to a limit ring 31. The end of the movable rod 30 away from the cam 3 is connected to the movable plate 20.

[0040] There are two fixed plates 32, which are symmetrically arranged. The fixed plates 32 are fixedly connected to the inner side of the air outlet 10, and the moving rod 30 is slidably connected to the fixed plates 32.

[0041] Spring 33, there are two springs, which are symmetrical. Spring 33 is sleeved with moving rod 30. Spring 33 is located between fixed plate 32 and limit ring 31.

[0042] There are two motors 34, which are arranged at equal intervals. The output shaft of the motor 34 is fixed coaxially with the cam 3. The motor 34 is connected to the outer wall of the blower 1, and the output shaft of the motor 34 is rotatably connected to the outer wall of the blower 1.

[0043] When in use, if it is necessary to adjust the opening size of the air outlet 10, the motor 9 starts, and the output shaft of the motor 9 drives the cam 5 to rotate. The rotation of the cam 5 is transmitted to the baffle plate 2 through the moving rod 6, so that it moves along the track of the moving plate 4. The position of the baffle plate 2 adjusts the opening size of the air outlet 10, thereby precisely controlling the amount of air entering the incinerator. The spring 8 provides elastic support to ensure the smooth movement of the moving rod 6 and the baffle plate 2, which improves the reliability and durability of the adjustment unit.

[0044] Motor 34 is located on both sides of air outlet 10.

[0045] Working principle: When the incinerator processes waste or other materials, it generates high-temperature exhaust gas. This exhaust gas first enters the connected thermal oil furnace, where the thermal oil flowing inside absorbs the heat energy from the exhaust gas.

[0046] The heat exchanger is connected to the thermal oil furnace. The design of the heat exchanger allows the heat energy in the exhaust gas to be transferred to the thermal oil. This process is achieved through heat exchange. The thermal oil circulates in the heat exchanger and absorbs the heat energy of the exhaust gas.

[0047] The air supply for blower 1 is connected to the air inlet of blower 1 at the other end. The function of blower 1 is to provide the necessary airflow to incinerator 1 to ensure the efficiency and effectiveness of the incineration process;

[0048] An adjustment unit is provided on the air outlet 10 of the blower 1, including a baffle plate 2, a movable plate 20, a cam 3, a movable rod 30, a fixed plate 32, a spring 33, and a motor 34. This adjustment unit is used to precisely control the opening size of the air outlet 10.

[0049] Two motors 34 start synchronously. The output shaft of the motors 34 rotates, driving the cam 3 to rotate. When the cam 3 rotates, it pushes the moving rod 30, which in turn drives the spring 33 to extend or retract, thereby moving the two baffles 2 closer or further away. This adjusts the opening size of the air outlet 10. The spring 33 provides elastic support to ensure the smooth movement of the moving rod 30 and the baffles 2. By adjusting the airflow size at the air outlet, the amount of air entering the incinerator can be precisely controlled. This helps to optimize the combustion process, ensure the optimal ratio of fuel to air, and thus achieve more complete and efficient combustion.

[0050] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
