Description

Technical Field

[0001] This utility model relates to the field of taurine processing technology, and in particular to a temperature control device for a taurine reaction vessel. Background Technology

[0002] Taurine, also known as taurine or 2-aminoethanesulfonic acid, is one of the essential amino acids required by the human body under certain conditions. As a non-protein amino acid, taurine has significant physiological effects on physical performance and a series of unique functions in the cardiovascular system, enhancing physical fitness and relieving fatigue. Taurine also possesses anti-inflammatory, antipyretic, analgesic, anticonvulsant, and blood pressure-lowering effects. Furthermore, it plays a beneficial role in infant brain development, nerve conduction, visual function, and calcium absorption. Therefore, taurine is increasingly gaining broad commercial and social value in food, health products, medicine, and organic synthesis, with rapid market demand growth and promising application prospects.

[0003] Taurine is a white crystalline or powdery substance, readily soluble in water. Its main industrial production methods include the ethanolamine process and the ethylene oxide process. However, regardless of the production process, current taurine production inevitably involves the concentration and cooling crystallization of taurine aqueous solutions. Temperature control of the taurine reactor is a key factor affecting the refining, quality, and production cost of the taurine product. However, in existing technologies, compressor refrigeration is one of the main energy consumers in the plant, and excessive refrigeration capacity is prone to occur during operation, leading to wasted energy in the refrigeration system and increased production costs. Furthermore, impurities such as salt in the refrigeration brine can easily cause blockages in the compressor refrigeration unit. Summary of the Invention

[0004] The purpose of this invention is to provide a taurine reactor temperature control device with good cooling effect and low energy consumption, addressing the shortcomings of existing technologies.

[0005] The technical solution adopted in this utility model is as follows.

[0006] It includes a reaction vessel, an air-cooled condenser, an electromagnetic descaling device, a refrigeration unit, a frozen brine tank, a frozen brine pumping system, a first screen filter, and a second screen filter.

[0007] The outer circumferential surface of the reactor is equipped with a jacket, in which a refrigeration coil is coiled. The liquid outlet of the refrigeration coil, the air-cooled condenser, the electromagnetic descaling device, the refrigeration unit, the first screen filter, the frozen brine tank, the second screen filter, the frozen brine pumping system, and the liquid inlet of the refrigeration coil are connected in sequence through refrigeration pipelines.

[0008] The jacket of the reactor is equipped with a heating coil. The inlet of the heating coil is connected to the heat transfer oil heating device through a heating pipeline. The outlet of the heating coil is connected to the heat transfer oil heating device through a return oil pipe.

[0009] Its beneficial effects are as follows: After the frozen brine from the frozen brine tank enters the jacket of the reactor for cooling, it first enters the air-cooled condenser for preliminary cooling. This preliminary cooling causes crystals to precipitate from the brine. These crystals and impurities are then filtered out by an electromagnetic descaling device. The filtered brine then enters the refrigeration unit for further cooling before flowing back into the frozen brine tank. Because the brine is cooled and filtered before entering the refrigeration unit, it will not cause blockage of the compressor refrigeration device. Since the air-cooled condenser does not require a complex piping system, its installation is relatively simple, and its energy consumption is low. Cooling the brine before it enters the refrigeration unit results in lower power requirements and greater energy efficiency compared to using a refrigeration unit alone. Furthermore, it is safer than liquid ammonia.

[0010] As a preferred technical solution, the refrigeration unit includes a compressor and an evaporator. The compressor inlet is connected to a refrigerant supply pipe, and the compressor outlet is connected to a refrigerant return pipe. The evaporator inlet is connected to an electromagnetic descaling device through a refrigeration pipeline. The evaporator outlet is connected to a frozen brine tank through a refrigeration pipeline. A first screen filter is provided on the refrigeration pipeline.

[0011] As a preferred technical solution, the frozen brine tank includes a frozen brine inlet and a frozen brine outlet. The frozen brine inlet is connected to the outlet of the evaporator via a refrigeration pipeline, and a first screen filter is provided on the refrigeration pipeline. The frozen brine outlet is connected to the frozen brine pumping system via a refrigeration pipeline, and a second screen filter is provided on the refrigeration pipeline.

[0012] As a preferred technical solution, the frozen brine tank is equipped with a brine inlet, a water supply inlet, a level gauge, and a thermometer.

[0013] As a preferred technical solution, the frozen brine tank is equipped with a vent valve.

[0014] As a preferred technical solution, a cleaning port is provided on the bottom side of the frozen brine tank.

[0015] As a preferred technical solution, the frozen brine pumping system includes one or several parallel delivery pipelines, each equipped with a vacuum pump and several pipeline shut-off valves. With two parallel delivery pipelines, one in use and one on standby, the brine flow is relatively smooth.

[0016] As a preferred technical solution, Y-type filters are installed on each delivery pipeline. The presence of Y-type filters facilitates the removal of precipitates from the brine, ensuring smoother brine flow.

[0017] As a preferred technical solution, pressure gauges are installed on each delivery pipeline.

[0018] As a preferred technical solution, the reactor is equipped with a temperature measuring device, a pressure measuring device, a stirring device, a pressure relief valve, a feed inlet, and a discharge outlet. Attached Figure Description

[0037] like Figure 2 As shown, the jacket 10 of the reactor is equipped with a heating coil 14. The inlet 15 of the heating coil is connected to the heat transfer oil heating device 18 through the heating pipeline 17. The outlet 16 of the heating coil is connected to the heat transfer oil heating device through the return oil pipe 181.

[0038] like Figure 1 , 6 As shown, the refrigeration unit 4 includes a compressor 41 and an evaporator 42. The compressor inlet 45 is connected to the refrigerant supply pipe 43, and the compressor outlet 46 is connected to the refrigerant return pipe 44. The evaporator inlet 47 is connected to the electromagnetic descaling device 3 through a refrigeration pipeline, and a liquid pump 31 is provided on the refrigeration pipeline.

[0039] like Figure 1 As shown, the outlet 48 of the evaporator is connected to the frozen brine tank 5 via a refrigeration pipeline, and a first screen filter 7 is provided on the refrigeration pipeline.

[0040] The frozen brine tank 5 includes a frozen brine inlet 51 and a frozen brine outlet 52. The frozen brine inlet 51 is connected to the outlet 48 of the evaporator via a refrigeration pipeline, and a first screen filter 7 is provided on the refrigeration pipeline. The frozen brine outlet 52 is connected to the frozen brine pumping system 6 via a refrigeration pipeline, and a second screen filter 8 is provided on the refrigeration pipeline.

[0041] like Figure 5 As shown, the frozen brine tank 5 is equipped with a brine inlet 53, a water inlet 54, a level gauge 55, and a thermometer 56. The brine is calcium chloride. Water is supplied to the water inlet 54 through a water pipe 541.

[0042] The frozen brine tank 5 is equipped with a vent valve 57.

[0043] The frozen brine tank 5 has a cleaning port 58 on the bottom side.

[0044] like Figure 4 As shown, the frozen brine pumping system 6 includes a delivery pipeline 61, on which a vacuum pump 62 and two delivery pipeline shut-off valves 63 are installed.

[0045] Each delivery pipeline 61 is equipped with a pressure gauge 65. A Y-type filter 64 is also installed on each delivery pipeline 61. The Y-type filter 64 can remove impurities from the delivery pipeline 61.

[0047] Its beneficial effects are as follows: After the frozen brine in the frozen brine tank 5 enters the jacket 10 of the reactor 1 for cooling, it first enters the air-cooled condenser 2 for preliminary cooling. Through preliminary cooling, crystalline substances in the brine precipitate out. The crystalline substances and impurities are then filtered out by the electromagnetic descaling device 3. The filtered brine then enters the refrigeration unit 4 for further cooling before flowing back into the frozen brine tank 5. Because the brine is cooled and filtered, it will not cause blockage of the compressor refrigeration unit 4. Since the air-cooled condenser does not require a complex piping system, its installation is relatively simple and its energy consumption is low. Cooling the brine before it enters the refrigeration unit 4 results in lower power requirements for the refrigeration unit 4 compared to using the refrigeration unit 4 alone, making it more energy-efficient. The brine is a calcium chloride aqueous solution, which is safer than liquid ammonia.

With two parallel delivery pipelines 61, one in use and one on standby, the brine flow is relatively smooth. Each delivery pipeline 61 is equipped with a Y-type filter 64. The Y-type filter 64 facilitates the removal of precipitates from the brine, ensuring smooth brine flow.
