Description

Technical Field

[0001] The utility model relates to the technical field of heat recovery devices, in particular to heat transfer and recycling equipment for chemical equipment. Background Art

[0002] Heat transfer recycling refers to the effective recovery and reuse of heat during energy conversion or transmission. This usually involves converting waste heat into useful thermal energy or other forms of energy to reduce energy waste and improve energy efficiency. Heat transfer recycling plays a vital role in the chemical industry, effectively reducing energy consumption, reducing emissions and improving production efficiency.

[0003] After searching, Chinese patent No. CN202122245121.0 discloses a heat transfer and recycling device for chemical equipment, including a reactor, a discharge pipe and a feed pipe are provided on the side wall of the reactor, the discharge pipe and the feed pipe both pass through the side wall of the reactor and are connected to the interior of the reactor, a power trough is provided on the side wall of the reactor, a heat transfer device is provided on the power trough and the discharge pipe, a feed pipe is fixedly connected to the side wall of the reactor, the feed pipe is connected to the feed pipe, and the feed pipe is arranged at an angle.

[0004] The beneficial effects of the above device are as follows: when the reactor begins to carry out a chemical reaction, the processed chemical product flows out along the discharge pipe. At this time, the temperature of the chemical raw materials after the reaction is very high. With the release of heat, they are transported out from the transmission belt along the transport pipe. During the transportation process, heat will be continuously released along the heat conduction pipe to heat the feed pipe. At this time, the temperature of the feed pipe rises and starts to preheat the raw materials passing through the feed pipe. Raising the temperature of the raw materials for early preheating can reduce the reaction time in the reactor, thereby improving the processing efficiency. This solves the problem in the existing technology that the heat generated by the chemical product reaction cannot be effectively utilized and the utilization rate is low. It not only speeds up the reaction time and improves production efficiency, but also efficiently utilizes the heat generated by the reaction.

[0005] Although the existing heat transfer recycling equipment can effectively recycle waste heat during operation, the waste heat contains a large amount of harmful gases such as dust and impurities. During the waste heat recovery process, the waste gas will be recovered at the same time, resulting in the recycling of harmful gases in the waste gas and causing pollution. To this end, we propose a heat transfer recycling equipment for chemical equipment. Utility Model Content

[0023] A heat transfer and recycling device for chemical equipment, wherein a discharge pipe 2 and a feed pipe 3 are fixedly connected to the surface of the chemical equipment 1, the feed pipe 3 is used to add chemical raw materials to be reacted into the chemical equipment 1, and the discharge pipe 2 is used to discharge chemical products produced after the chemical raw materials in the chemical equipment 1 react. A waste heat recovery mechanism is installed between the discharge pipe 2 and the feed pipe 3, and through the operation of the waste heat recovery mechanism, the waste gas when the chemical products are discharged from the discharge pipe 2 can be recovered to reduce pollution, and the heat in the waste gas can be recovered at the same time, and the recovered heat can be used to heat the feed pipe 3, so that when the chemical raw materials to be reacted are added into the feed pipe 3, the chemical raw materials are preheated when passing through the feed pipe 3, thereby improving the processing efficiency of the chemical raw materials by the chemical equipment 1.

[0024] The waste heat recovery mechanism includes a heat recovery pipe 4 installed between the discharge pipe 2 and the feed pipe 3. The heat recovery pipe 4 is fixedly connected to the surface of the discharge pipe 2 and communicated with the inside of the discharge pipe 2. When the discharge pipe 2 is discharged, the waste gas in the material will enter the heat recovery pipe 4. Through the internal structure of the heat recovery pipe 4, the heat in the waste gas can be recovered and reused. The waste heat recovery mechanism includes a hot water absorption pipe 5 connected to the inside of the heat recovery pipe 4. The hot water absorption pipe 5 is installed in a vertical state inside the heat recovery pipe 4. Further, when the discharge pipe 2 is discharged, the chemical product will discharge a large amount of hot gas at the same time. The hot gas will enter the heat recovery pipe 4 and further heat the surface of the hot water absorption pipe 5. The surface of the heat recovery pipe 4 is fixedly connected with a purified water tank 12. A water pump is installed in the purified water tank 12. The water pump is connected to the hot water absorption pipe 5 through a water supply pipe 13. Further, the water pump in the purified water tank 12 can transport the water to the hot water absorption pipe 5, and further, when the hot water absorption pipe 5 is heated by the exhaust gas, the water in the hot water absorption pipe 5 can absorb the heat in the exhaust gas to achieve exhaust gas cooling. The upper end of the heat recovery pipe 4 is also equipped with a preheating pipe 7, one end of the preheating pipe 7 inserted in the heat recovery pipe 4 is connected to the hot water absorption pipe 5, and the other end of the preheating pipe 7 penetrates the outside of the heat recovery pipe 4 and is spirally wound and distributed on the surface of the feed pipe 3. When the water in the hot water absorption pipe 5 is heated, it will be actively transported to the preheating pipe 7, and further, when the water flows in the preheating pipe 7, the heat will be dissipated to the surface of the feed pipe 3, realizing heat transfer and heating the inside of the feed pipe 3. Further, when the chemical raw materials to be reacted are added to the feed pipe 3, the chemical raw materials are preheated when passing through the feed pipe 3, thereby improving the processing efficiency of the chemical equipment 1 for the chemical raw materials.

[0025] Several groups of heat-absorbing pipes 5 are arranged inside the heat recovery pipe 4 in an equidistant linear distribution. The two ends of the several groups of heat-absorbing pipes 5 are respectively connected to the preheating pipe 7 and the water supply pipe 13, so that the exhaust gas can absorb heat more fully during the flow in the heat recovery pipe 4, thereby improving the heat recovery efficiency. Heat-absorbing fins 6 are fixedly connected to the surfaces of both sides of each group of heat-absorbing pipes 5. The heat-absorbing fins 6 are arranged in a bent shape, so that when the hot gas flows in the heat recovery pipe 4, the heat recovery pipe 4 can increase the absorption area of ​​the hot gas and improve the heat absorption efficiency. Several groups of heat-absorbing fins 6 are fixedly connected to the surface of each group of heat-absorbing pipes 5 in an equidistant linear distribution, thereby further improving the working efficiency of the device.

[0026] The surface of the heat recovery pipe 4 is fixedly connected with a filter pipe 8, and the filter pipe 8 is connected to the heat recovery pipe 4. The other end of the filter pipe 8 is fixedly connected with a negative pressure pump 9. After the negative pressure pump 9 is turned on, negative pressure is formed, and the filter pipe 8 and the heat recovery pipe 4 can actively suck the exhaust gas from the discharge pipe 2, thereby improving the recovery efficiency of the exhaust gas. In addition, the inside of the filter pipe 8 is fixedly connected with a filter element 10, and the impurities in the exhaust gas can be filtered through the filter element 10 to achieve the cleaning of the exhaust gas. In addition, when the exhaust gas flows in the heat recovery pipe 4, the heat in the exhaust gas can be absorbed by the hot water absorption pipe 5, further avoiding the damage of the filter element 10 caused by the high temperature in the exhaust gas, thereby extending the service life.

[0027] The upper end surface of the filter tube 8 is fixedly connected with a nozzle 11, which is located above the filter element 10, and the other end of the preheating tube 7 is connected to the nozzle 11. When the water flows in the preheating tube 7, the heat absorbed by the water will be transferred to the feed pipe 3 to cool the water. After the cooled water is further transported to the nozzle 11, it is sprayed on the surface of the filter element 10 through the nozzle 11, which can achieve the cleaning and cooling of the filter element 10, thereby ensuring the filtering effect of the filter element 10. The purified water tank 12 is installed below the filter tube 8 and is located below the filter element 10. The lower end surface of the filter tube 8 is provided with a drain port located between the filter element 10 and the purified water tank 12, so that the water sprayed by the nozzle 11 will be discharged into the purified water tank 12 after cleaning the filter element 10, so as to achieve the recovery of the water. The impurities in the water are purified by the purified water tank 12, so that the purified water is transported back to the hot water absorption pipe 5 for absorption, thereby realizing the recycling of the water.

[0028] The filter tube 8 is configured as a "U"-shaped structure, and the filter element 10 is located at the lowest end of the filter tube 8, so that when the nozzle 11 cleans the filter element 10, excess water will not enter the heat recovery tube 4, causing water to penetrate into the hot water absorption pipe 5 and cause contamination of the product.
