Description

Technical Field

[0001] This invention relates to the field of chemical production technology, specifically to a condensate heat exchange and steam enhancement device that utilizes the waste heat of mother liquor. Background Technology

[0002] Condensate heat exchange and steam efficiency enhancement devices that utilize the waste heat of mother liquor are core energy-saving equipment in industries such as chemical, pharmaceutical, and food processing. Their core function is to recover the waste heat emitted from mother liquor during industrial production, heat the condensate through a heat exchange system, and thus improve steam generation efficiency.

[0003] The device mainly involves the high-temperature mother liquor entering the recovery module, where heat is transferred to the low-temperature condensate through a heat exchanger. The preheated condensate is then sent to a boiler to generate steam, and the mother liquor is discharged or recycled after cooling.

[0004] However, the above-mentioned equipment has certain shortcomings in use. In the acetic acid production system, the temperature at the bottom of the evaporator is maintained at around 140℃. The mother liquor pump connected to the bottom is adversely affected by the high inlet temperature. Although the outlet of the mother liquor pump is cooled by the circulating water heat exchanger, the temperature of the high-temperature mother liquor only drops to 115-130℃ after returning to the reactor. Moreover, there is unavoidable heat loss at both the inlet and outlet of the pump body, resulting in poor cooling effect of the mother liquor, which affects the service life of the pump and the operating efficiency of the system.

[0023] Please see Figures 1-9 The present invention provides a technical solution: A condensate heat exchange and steam enhancement device that utilizes the waste heat of mother liquor includes a heat exchanger shell 1.

[0024] In one embodiment of the present invention, a heat exchange assembly 2 is provided on the heat exchanger shell 1. The heat exchange assembly 2 includes a heat exchanger inner liner 21, which is fixedly installed inside the heat exchanger shell 1. A mother liquor inlet pipe 22 is fixedly installed at one end of the heat exchanger shell 1. A pressure gauge 23 is fixedly installed above the heat exchanger shell 1, and a detection rod 24 is fixedly installed below the heat exchanger shell 1. A temperature sensor 25 is fixedly installed on the detection rod 24. A pressure regulating valve 26 is fixedly installed on the heat exchanger inner liner 21. A condensate pipe 27 is fixedly installed at the other end of the heat exchanger shell 1. A partition 28 is fixedly installed inside the heat exchanger inner liner 21. A condensate inlet pipe 29 is fixedly installed above the heat exchanger shell 1. The partition 28 is fixedly installed inside the heat exchanger inner liner 21, and the partition 28 has a connecting groove 210 and a circulation groove 211. A circular filter plate 212 is fixedly installed inside the condensate pipe 27. A heat absorption pipe 213 and a circulation pipe 214 are installed inside the heat exchanger inner liner 21. The mother liquor inlet pipe 22 is connected to the inside of the heat exchanger inner liner 21. The detection end of the pressure gauge 23 is connected to the inside of the heat exchanger inner liner 21. The condensate pipe 27 is connected to the inside of the heat exchanger inner liner 21. The partition block 28 is located at the center of the heat exchanger inner liner 21. Both the heat absorption pipe 213 and the circulation pipe 214 are spiral. The heat absorption pipe 213 is wound around the mother liquor inlet pipe 22. The condensate inlet pipe 29 is connected to the connecting groove 210 on the partition block 28. One end of the heat absorption pipe 213 is connected to the connecting groove 210. The other end of the heat absorption pipe 213 is connected to the circulation tank 211. The other end of the circulation tank 211 is connected to the circulation pipe 214. The detection rod 24 is located inside the circulation tank 211.

[0025] In this embodiment, the high-temperature mother liquor from acetic acid production flows into the heat exchanger inner tank 21 through the mother liquor inlet pipe 22. The circular filter plate 212 inside the mother liquor inlet pipe 22 first filters impurities in the mother liquor to prevent impurities from entering the inner tank and causing pipe blockage. The spiral heat absorption tube 213 wrapped around the outside of the mother liquor inlet pipe 22 makes full contact with the mother liquor to maximize the absorption of residual heat from the mother liquor, causing the mother liquor temperature to drop rapidly. This effectively solves the operational hazard of excessively high inlet temperature of the acetic acid mother liquor pump and extends the service life of the mother liquor pump. At the same time, the condensate from the flash evaporation tank is transported to the connecting groove 210 of the partition block 28 through the condensate inlet pipe 29, and then flows into the heat absorption tube 213. After absorbing residual heat from the mother liquor in the heat absorption tube 213, it flows into the circulation tank 211. The temperature sensor on the detection rod 24... Sensor 25 monitors the temperature of the condensate in the circulation tank 211 in real time, controlling the heating state of the condensate. The condensate then enters the spiral circulation pipe 214, which further absorbs the residual heat in the heat exchanger inner tank 21 and is heated to near the vaporization temperature. Finally, it is discharged through the condensate pipe 27. The circular filter plate 212 inside filters impurities in the condensate, providing high-temperature condensate raw material for subsequent secondary steam generation. The partition 28 divides the inside of the heat exchanger inner tank 21 into a mother liquor heat exchange zone and a condensate circulation zone, preventing fluid mixing from affecting the heat exchange effect. Pressure gauge 23 monitors the internal pressure of the heat exchanger inner tank 21 in real time. When the pressure exceeds the preset threshold of the acetic acid process, the pressure regulating valve 26 automatically opens to release pressure, ensuring stable operating pressure of the device.

[0026] In one embodiment of the present invention, a steam circulation assembly 3 is provided on the heat exchanger shell 1. The steam circulation assembly 3 includes a square filter plate 31, which is fixedly installed on the heat exchanger shell 1. An installation box 32 is fixedly installed on the heat exchanger shell 1. An inclined air guide plate 34 is fixedly installed on the installation box 32. A motor 35 is fixedly installed on the installation box 32. A fan blade 36 is fixedly installed at the output end of the motor 35. A triangular air guide plate 37 is fixedly installed on the square filter plate 31. A long filter plate 38 is fixedly installed inside the installation box 32. Multiple sets of motors 35 and fan blades 36 are provided. The installation box 32 is located above the square filter plate 31 and is connected to the internal space of the heat exchanger shell 1. The fan blades 36 face the long filter plate 38 and the inclined air guide plate 34. Multiple sets of fan blades 36 are located below the maintenance plate 33 and above the triangular air guide plate 37. The maintenance plate 33 is snapped onto the installation box 32.

[0027] In this embodiment, during use, the high-temperature condensate in the heat absorption pipe 213 and circulation pipe 214 partially vaporizes to form steam, which accumulates inside the heat exchanger outer shell 1. Multiple motors 35 on the mounting box 32 are activated, driving the fan blades 36 to rotate at high speed, generating a directional airflow that blows downwards towards the inner liner 21 of the heat exchanger, accelerating the flow of steam within the liner and preventing localized steam stagnation. During the upward movement of the airflow and steam, they are first guided by the triangular guide plates 37 on the square filter plate 31, achieving directional steam convergence and ensuring the steam flows evenly to the steam distribution pipe. Subsequently, the steam passes sequentially through the square filter plate. The long filter plate 38 inside the mounting box 31 and the mounting box 32 completes dual filtration, effectively intercepting impurities and unvaporized condensate droplets in the steam, avoiding impurities from affecting the steam quality, and ensuring that the overall steam pressure and flow parameters are precisely matched to the heating coupling requirements of the ethyl ester section after the steam from the acetic acid waste boiler is merged. The inclined guide plate 34 further guides the airflow direction generated by the fan blades 36, improving the steam convergence efficiency. The maintenance plate 33 on the mounting box 32 can be quickly snapped on and removed, which is convenient for later cleaning of the long filter plate 38, maintenance of the motor 35 and fan blades 36, and reduces the difficulty of equipment maintenance.

[0028] In one embodiment of the present invention, an auxiliary component 4 is provided on the heat exchanger shell 1. The auxiliary component 4 includes a cross mounting bracket 41, which is fixedly mounted on the heat exchanger inner liner 21. A conical cylinder 42 is fixedly mounted on the cross mounting bracket 41. A round rod 43 is rotatably mounted inside the conical cylinder 42. A propeller 44 is fixedly mounted at one end of the round rod 43, and an auxiliary fan 45 is fixedly mounted at the other end of the round rod 43. Multiple sets of the cross mounting bracket 41, conical cylinder 42, round rod 43, propeller 44, and auxiliary fan 45 are provided. The multiple sets of propeller 44 and auxiliary fan 45 correspond to the positions of the mother liquor inlet pipe 22 and the condensate inlet pipe 29. The auxiliary fan 45 is located inside the mother liquor inlet pipe 22 and the condensate inlet pipe 29. The conical cylinder 42 is fixedly mounted at the center position of the cross mounting bracket 41.

[0029] In this embodiment, when the high-temperature mother liquor flows from the mother liquor inlet pipe 22 into the heat exchanger inner liner 21, it impacts the propeller 44 at the corresponding position, driving the round rod 43 to rotate inside the conical cylinder 42. This, in turn, drives the auxiliary fan 45, which is located inside the mother liquor inlet pipe 22, to rotate synchronously. The rotation of the auxiliary fan 45 breaks the laminar flow state of the mother liquor, enhances the turbulence of the mother liquor, and makes the contact between the mother liquor and the heat absorption tube 213 more complete, allowing the residual heat of the mother liquor to be released more thoroughly and improving the cooling effect of the mother liquor. At the same time, the condensate flows from the condensate inlet pipe 29... When the liquid flows into the connecting groove 210, it impacts another set of propellers 44 at the corresponding position, causing its round rod 43 and the auxiliary fan 45 inside the condensate inlet pipe 29 to rotate. This also enhances the turbulence of the condensate, making the flow of the condensate in the heat absorption pipe 213 and the circulation pipe 214 more uniform, avoiding local heat exchange dead zones, ensuring that all parts of the condensate can fully absorb residual heat, and improving the heating efficiency of the condensate. The cross mounting bracket 41 provides a stable mounting base for the conical cylinder 42, ensuring the stability of the round rod 43 when it rotates.
