Description
Technical Field
[0001] This utility model specifically relates to the field of waste heat recovery devices, and more specifically to an environmentally friendly waste heat recovery device for pressure vessels. Background Technology
[0002] With the advancement of global industrialization, energy demand continues to rise, while environmental protection requirements are becoming increasingly stringent. Pressure vessels are widely used in numerous fields such as chemical, power, and metallurgy, generating significant amounts of waste heat during operation. Under traditional energy utilization methods, this waste heat is often directly released into the environment, causing not only energy waste but also environmental problems such as thermal pollution. Therefore, in response to the call for energy conservation and emission reduction, to improve the comprehensive utilization rate of energy, and to reduce enterprise production costs, the development of environmentally friendly pressure vessel waste heat recovery devices has become an inevitable trend.
[0003] During the operation of traditional pressure vessels, the high-temperature gas discharged from the exhaust pipe often carries a large amount of waste heat. Directly releasing this waste heat not only wastes energy but also causes thermal pollution to the environment. Furthermore, the exhaust gas may contain impurities, and direct discharge without treatment will exacerbate environmental pollution. With the increasing awareness of energy conservation and environmental protection and the stringent requirements of relevant policies and regulations, the development of an environmentally friendly device that can both recover waste heat and purify exhaust gas is urgently needed. Existing waste heat recovery devices have shortcomings in terms of structural rationality, waste heat recovery efficiency, and gas purification effect, making it difficult to meet the ever-increasing demands for environmental protection and energy conservation.

[0030] Please see Figure 1-7In this embodiment of the present invention, an environmentally friendly pressure vessel waste heat recovery device includes a pressure vessel body 1, one end of which is fixedly connected to a recovery device 2 by bolts; the other end of the recovery device 2 is fixedly connected to a filter device 3 by bolts.
[0031] The recovery device 2 includes a heat exchange box 21, which is designed in the shape of a rectangular frame and has an air inlet 23 and an air outlet 24 at both ends, respectively. The air inlet 23 is fixedly connected to the air outlet pipe 16 by bolts.
[0032] The heat exchange box 21 is provided with a mounting bracket 22 on the inner side. Heat exchange tubes 25 arranged in a regular pattern are mounted on the mounting bracket 22. The two ends of the heat exchange tubes 25 are respectively provided with an inlet 27 and an outlet 26. The inlet 27 is located at the upper outer side of the heat exchange box 21, and the outlet 26 is located at the lower outer side of the heat exchange box 21. A temperature sensor 28 is provided on the upper surface of the heat exchange box 21. The bottom of the temperature sensor 28 is connected to the inner side of the heat exchange box 21.
[0033] The air outlet pipe 16 is located at the front end of the cylinder 12. The lower surface of the cylinder 12 is symmetrically equipped with a fixing frame 11, and the upper surface of the cylinder 12 is provided with an upper pipe 13. The upper end of the upper pipe 13 is fixedly connected to the safety valve.
[0034] The rear end of the cylinder 12 is provided with an air inlet pipe 14, and the other end of the air inlet pipe 14 is fixedly connected to an air source device; the lower surface of the cylinder 12 is also provided with a lower pipe 15, and the lower end of the lower pipe 15 is fixedly connected to a discharge device.
[0035] By adopting the above technical solution, the waste heat of the gas discharged from the pressure vessel body 1 is recovered through the heat exchange tube 25, and the waste heat is converted into usable thermal energy for preheating, heating and other processes, which improves the comprehensive utilization rate of energy, reduces the enterprise's dependence on external energy, and saves energy costs.
[0036] The temperature sensor 28 can monitor the temperature inside the heat exchange box 21 in real time, providing operators with accurate data so that relevant parameters can be adjusted in a timely manner, ensuring that the waste heat recovery process is always in an efficient and stable operating state.
[0037] In this embodiment, the air outlet 24 at one end of the heat exchange box 21 is fixedly connected to the filter air inlet 33 by bolts. The filter air inlet 33 is located on one side of the filter box 31. Each of the four corners of the bottom of the filter box 31 is provided with a support leg 32, and the upper surface of the filter box 31 is provided with a filter air outlet 35.
[0038] Two guide plates 34 are connected between the filter inlet 33 and the filter outlet 35. The two ends of the guide plates 34 are fixedly connected to the inside of the filter housing 31. Two activated carbon filter plates 36 are installed between the two guide plates 34, one above the other. The two ends of the activated carbon filter plates 36 are also fixedly connected to the inside of the filter housing 31.
[0039] By adopting the above technical solution, the activated carbon filter plate 36 in the filter device 3 can effectively adsorb and remove impurities and pollutants in the exhaust gas, reduce the pollution of the environment by the exhaust gas, meet the environmental protection requirements, and help protect the atmospheric environment.
[0040] The working principle of this utility model is as follows: When the pressure vessel body 1 is running, the gas with residual heat is discharged from the gas outlet pipe 16 at the front end of the cylinder and enters the gas inlet 23 of the heat exchange box 21 of the recovery device 2 through bolt connection. During the flow of the gas in the heat exchange box, it exchanges heat with the heat exchange tubes 25 arranged regularly on the mounting frame 22. Cold water flows in from the water inlet 27 of the heat exchange tube, absorbs the residual heat of the gas, and flows out from the water outlet 26 to realize the recovery and utilization of residual heat. The temperature sensor 28 on the upper surface of the heat exchange box monitors the temperature inside the box in real time, which facilitates the control of the residual heat recovery process.
[0041] After waste heat recovery, the gas flows out from the outlet 24 at one end of the heat exchange box 21 and enters the filter inlet 33 of the filter box 31 of the filter device 3 through bolt connection. In the filter box, the gas is guided by the guide plate 34 and changes its flow direction. It passes through two activated carbon filter plates 36 in sequence. The activated carbon filter plates use their adsorption characteristics to adsorb and filter impurities and harmful substances in the gas. The purified gas is discharged from the filter outlet 35 on the upper surface of the filter box.
[0042] The activated carbon filter plate 36 in the filter device 3 can effectively adsorb and remove impurities and pollutants in the exhaust gas, reduce the pollution of the exhaust gas to the environment, meet environmental protection requirements, and help protect the atmospheric environment.
[0043] The waste heat of the gas discharged from the pressure vessel body 1 is recovered through the heat exchange tube 25 and converted into usable thermal energy for preheating, heating and other processes, which improves the comprehensive utilization rate of energy, reduces the enterprise's dependence on external energy and saves energy costs.
[0044] The temperature sensor 28 can monitor the temperature inside the heat exchange box 21 in real time, providing operators with accurate data so that relevant parameters can be adjusted in a timely manner, ensuring that the waste heat recovery process is always in an efficient and stable operating state.
