Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of energy conversion, in particular to a preheating system for recovering heat energy from an incinerator. Background Art
[0002] The incinerator is mainly used for harmless treatment of various waste gases generated during the production of the device, especially gases harmful to the environment. After incineration, it can produce 340 tons of 13MPa steam / 24 hours. The operation of the equipment is directly related to the safety and environmental protection of the entire device. It is a key equipment unit. The incinerator mainly accepts the waste gas from the device for high-temperature treatment. When the waste gas is sufficient, the gas pipeline network will add a small amount of auxiliary fuel gas to make the incineration more complete and 100% meet the emission standards. When the device is shut down or the waste gas is insufficient, the fuel gas pipeline network will serve as a supplement to keep the torch lit.
[0003] However, the existing incinerator maintains a furnace temperature of 1100°C all year round, and the boiler outer wall temperature is maintained at around 120°C all year round. The heat of the main body cannot be recovered, nor can the desalted water be preheated by heat. The use of steam heat source is increased, thereby consuming more energy and increasing production and operation costs. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-Figure 4 A heat recovery preheating system for an incinerator comprises a furnace body 1, the upper surface of which is fixedly sleeved with a feed port 2 and a gas pipe 3, one end of the gas pipe 3 is fixedly sleeved with the inlet of a filter 4, and the upper surface of the filter 4 is fixedly sleeved with an airflow pipe 5.
[0020] One end of the airflow tube 5 is fixedly connected with a heat exchanger 7, and the upper surface of the heat exchanger 7 is movably connected with a device cover 8. The upper surface of the device cover 8 is fixedly connected with one end of the airflow tube 5 through the airflow port to determine the position of the device cover 8, and the filtered gas enters the heat exchanger 7 through the airflow tube 5.
[0021] The circumferential side of the cover 8 is fixedly mounted with symmetrically distributed buckles 9, the circumferential side of the upper end of the heat exchanger 7 is provided with a square groove, the inner wall of the square groove is movably engaged with the surface of one side of the buckle 9, and the circumferential side of the heat exchanger 7 is respectively provided with a cold inlet 10, a cold outlet 11 and a discharge port 12. The design of the square groove and the buckle 9 allows the cover 8 to be stuck and fixed, and can also be removed for easy cleaning of the inside of the heat exchanger 7.
[0022] The inner wall of the heat exchanger 7 is movably connected with an S water pipe 13, and the inner wall of the S water pipe 13 is provided with a circular groove 14. The circular groove 14 is fixedly installed with evenly distributed heat absorbing rings 15. The position of the circular groove 14 is determined, and the heat absorbing ring 15 in the circular groove 14 can heat the gas in the S water pipe 13.
[0023] A thread groove 16 is provided on the outer surface of the transversely distributed section of the S water pipe 13, and a heat conducting strip 17 is fixedly installed on the inner wall of the thread groove 16. The material of the heat conducting strip 17 is alumina. The peripheral surface of the heat conducting strip 17 is fixedly connected with a heat sink 6 with a fan-shaped structure. The material of the heat sink 6 is graphite. The setting of the thread groove 16 enables the heat conducting strip 17 in the thread groove 16 to evenly distribute heat to the gas in the S water pipe 13, avoiding the generation of hot spots or cold spots and improving the accuracy of temperature control. The heat sink 6 on the heat conducting strip 17 can help reduce the temperature and evenly distribute the heat.
[0024] One end of the airflow tube 5 is fixedly connected to one end of the S water pipe 13, and one end of the S water pipe 13 is fixedly connected to one end of the discharge port 12 to determine the position of the discharge port 12. The gas enters the S water pipe 13 through the airflow tube 5 and is finally discharged from the discharge port 12.
[0025] By setting up the heat exchanger 7, the gas after filtering out dust enters the S water pipe 13 through the airflow pipe 5. The heat absorption ring 15 in the S water pipe 13 adsorbs the heated gas and the fluid to be heated, releases the absorbed heat and transfers it to the fluid to be heated to achieve preheating. The heat of the gas in the S water pipe 13 will be transferred to the fluid entering the heat exchanger 7 through the cold inlet 10, and the fluid transfers the heat to the heat load. In this process, heat energy is recovered and reused, and the recovered heat is used to preheat the desalted water, thereby reducing the use of steam heat source, and ultimately achieving the purpose of saving energy and reducing production and operation costs.
[0026] Working principle: Pour the material into the feed port 2 and burn it in the incinerator. The combustion exhaust gas flows into the filter 4 through the gas pipe 3. The filtered gas flows into the S water pipe 13 in the heat exchanger 7 through the air flow pipe 5. The heat absorption ring 15 in the S water pipe 13 adsorbs the heated gas and the fluid to be heated, and releases the absorbed heat to transfer to the fluid to be heated to achieve preheating.
[0027] The heat of the gas in the S water pipe 13 will be transferred to the fluid entering the heat exchanger 7 through the cold inlet 10. The process of heat transfer between the two fluids can recover and reuse the heat energy. The materials used for the heat conducting strips 17 and the heat dissipating blocks 6 are corrosion-resistant and have better heat conduction and heat dissipation, which plays a role in uniform heat distribution, thereby reducing the use of steam heat source, and ultimately achieving the purpose of saving energy and reducing production and operation costs. At the same time, the cover 8 on the heat exchanger 7 can be removed to clean the inside of the heat exchanger.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
