[0002] Nitrous oxide (N 2 Nitrous oxide (N O), also known as laughing gas, is a colorless, sweet-tasting gas that is commonly used in many fields such as medicine, industry, and agriculture. 2 O) Gas purification heat exchanger is a device used to remove nitrous oxide from gas, usually used in industrial production processes to reduce greenhouse gas emissions. Heat exchanger is a device used to transfer heat, widely used in various industrial and engineering fields. Its main function is to efficiently transfer heat from one fluid (gas or liquid) to another fluid, rather than directly mixing the two.

The key points of its technical solution are: including a mounting base, an impurity removal device, a purification heat exchange device, a one-way power generation device, and a transmission belt. The impurity removal device removes adsorbable impurities in the gas and drives the one-way power generation device to rotate under the impact of the gas. The purification heat exchange device removes water-soluble impurities in the gas and absorbs heat in the gas to heat water. The one-way power generation device receives kinetic energy to generate electricity and other functions. It is characterized in that: the impurity removal device is installed and fixed on the mounting base, the purification heat exchange device is installed and fixed on the mounting base, the one-way power generation device is installed and fixed on the mounting base, the transmission belt is installed on the impurity removal device, and the transmission belt is installed on the one-way power generation device.

When the heat exchange device is in use, some condensation and scaling will be generated. The cleaning mechanism is used to rotate around the inner wall of the heat exchange device to remove the scaling generated inside the heat exchange device. When cleaning, a single cleaning rod 27 is provided in the cleaning mechanism to reduce the occupied space, and the inside of the heat exchange device can be cleaned quickly and conveniently during daily care, thereby improving work efficiency, removing dirt inside the heat exchange device, and ensuring smooth transfer of heat flow, thereby improving heat transfer efficiency, and ensuring the optimal performance of the equipment.

[0025] One end of the cleaning rod 27 is fixedly connected to the second external gear 28, and the outer surface of the second external gear 28 is meshed with the second internal gear 29. One end of the second external gear 28 is rotatably connected to the second connecting rod 30, and one end of the second connecting rod 30 is rotatably connected to the third connecting rod 31. One end of the third connecting rod 31 is clamped on the surface of the second internal gear 29. Condensation and scaling will occur inside during heat exchange. The drive motor 23 is started, and the drive motor 23 drives the first connecting rod 24 to rotate. The first connecting rod 24 drives the first external gear 25 to rotate on the surface of the first internal gear 26. The first internal gear 26 is fixed around the inner wall of the outer shell 1. When the first external gear 25 rotates, it drives the cleaning rod 27 to rotate inside the outer shell 1, so as to remove the scaling on the inner wall of the outer shell 1. When the cleaning rod 27 rotates, the other end drives the second external gear 28 to rotate on the second internal gear 29, thereby playing a role of auxiliary fixation.

[0026] The water cooling circulation mechanism includes a water pump 32, the outer surface of the water pump 32 is fixedly connected to one side of the support 3, the input end of the water pump 32 is fixedly connected to a water inlet pipe 33, the output end of the water pump 32 is fixedly connected to a water outlet pipe 34, and one end of the water outlet pipe 34 is fixedly connected to a water cooling pipe 35.

[0027] The inner wall of the support 3 is fixedly connected to a water tank 36, and a shielding cover 37 is clamped on the upper surface of the water tank 36. The upper surface of the shielding cover 37 is provided with holes and grooves for plugging in the water inlet pipe 33 and the water cooling pipe 35. The shielding cover 37 is made of transparent acrylic. The shielding cover 37 can prevent impurities from entering the water tank 36, thereby achieving a dust-proof effect.

[0028] A drain pipe 38 is fixedly connected to the bottom of the outer surface of the shell 1, and an exhaust pipe 39 is fixedly connected to the top of the outer surface of the shell 1. Dirt in the shell 1 can be discharged from the drain pipe 38 to ensure the cleanliness of the inside of the shell 1. During heat exchange, the gas inside the shell 1 is discharged from the exhaust pipe 39.

[0029] A flange 40 is fixedly connected to one end of the outer shell 1, and a head 41 is threadedly connected to the outer surface of the flange 40 through a fixing bolt. An air inlet pipe 42 is fixedly connected to one end of the head 41. After the nitrous oxide is manufactured, the nitrous oxide is collected into the inner part of the outer shell 1 through the air inlet pipe 42. If it is necessary to repair the internal parts of the outer shell 1, the flange 40 and the head 41 are removed to expose the outer shell 1.

[0030] Both sides of the support 3 are fixedly connected with fixing plates 43, and the surface of the fixing plates 43 is provided with threaded holes, and the internal threads of the threaded holes are connected with bolts 44. When the support 3 needs to be fixed, it is fixed with the fixing plates 43 and bolts 44 to avoid sliding and enhance firmness.

[0031] Working principle: After the nitrous oxide is manufactured, the nitrous oxide is collected into the shell 1 by the air inlet pipe 42, and the heat transfer pipe 2 is used to transfer the hot air. When transferring the hot air, in order to improve the heat transfer efficiency, the telescopic heating pipe 5 is started to increase the temperature of the telescopic heating plate 4. According to the required contact surface, the electric push rod 21 is started, and the electric push rod 21 drives the push block 22 to stretch the length of the telescopic heating plate 4 and adjust it to a suitable width to achieve the temperature control effect. Subsequently, the double-axis telescopic rod 8 is started, and the double-axis telescopic rod 8 drives the slider 9 to extend and retract up and down in the slide plate 6. The slider 9 drives the telescopic heating plate 4 and the telescopic bonding plate 10 to extend and retract close to the outer surface of the heat transfer pipe 2. The telescopic heating plate 4 heats the heat transfer pipe 2, which can improve the heat transfer efficiency. Improving the heat transfer efficiency can be more effective Recycle and utilize waste heat, improve the overall energy recovery rate and thermal efficiency of the system, and the efficient heat exchange device can better recycle the waste heat generated in the industrial process, reuse the heat, improve energy utilization, and reduce energy waste. Due to the reduction in energy consumption, related greenhouse gas emissions will also be reduced, which will help alleviate environmental pollution and promote sustainable development. Subsequently, during heating, steam will be generated during the heat exchange, and the high-temperature waste heat generated during the preparation process can flow along the telescopic bonding plate 10 in the groove plate 13, flow from the groove plate 13 to the first connecting pipe 12, flow in the telescopic flow pipe 11, flow out from the outflow pipe 14, flow to the second connecting pipe 15 and the third connecting pipe 16, and then be released from the discharge pipe 17, which is convenient for personnel to recycle and utilize again. Then, when temperature control is required, the double-axis telescopic rod 8 is started again to push the telescopic heating plate 4 and the telescopic bonding plate 10 outward, away from the heat transfer tube 2, and the telescopic heating tube 5 is closed. Then, when water cooling circulation is required, cold water is put into the water tank 36, and the water pump 32 is started. The water pump 32 uses the water inlet pipe 33 to draw cold water into the water tank 36, and flows out from the water outlet pipe 34 and flows into the water cooling pipe 35. The water cooling pipe 35 is arranged around the inside of the shell 1. When the cold water flows in the water cooling pipe 35, the inside of the shell 1 is cooled. When it flows to the tail end, the cold water flows in the water tank 36, thereby achieving a recycling effect. The water cooling circulation can provide a stable cooling effect, avoid the influence of thermal fluctuations on the performance of the equipment, and ensure the efficient operation of the heat exchange device. The water cooling circulation mechanism can effectively absorb and transfer heat, thereby improving the efficiency of the heat exchange process and reducing energy loss. Condensation and scaling will occur inside during heat exchange. The drive motor 23 is started, and the drive motor 23 drives the first connecting rod 24 to rotate. The first connecting rod 24 drives the first outer gear 25 to rotate on the surface of the first inner gear 26. The first inner gear 26 is fixed around the inner wall of the outer shell 1. When the first outer gear 25 rotates, it drives the cleaning rod 27 to rotate inside the outer shell 1, so as to remove the scaling on the inner wall of the outer shell 1. When the cleaning rod 27 rotates, the other end drives the second outer gear 28 to rotate on the second inner gear 29, which plays a role of auxiliary fixation. Subsequently, the dirt can be discharged from the drain pipe 38 to ensure the cleanliness of the inside of the outer shell 1. During heat exchange, the gas inside the outer shell 1 is discharged from the exhaust pipe 39.
