Description

Technical Field

[0001] The utility model relates to the technical field of stable operation of a cooling system of a chlorine turbine compressor in the chlor-alkali industry, and is an emergency treatment device for a cooling system of a chlorine turbine compressor. Background Art

[0002] Chlorine has strong oxidizing properties and can react with all metals under heating conditions. For example, gold and platinum burn in hot chlorine, and react with variable-valent metals such as Fe and Cu to produce high-valent metal chlorides. When the temperature of chlorine reaches 149°C, it will react violently with iron.

[0003] At present, the chlorine-alkali plant of a certain chemical enterprise uses a chlorine turbine compressor to perform secondary compression of chlorine to the required pressure. Only the compressed chlorine can enter the process system for preparing high-concentration alkali. In the process of compressing chlorine, the chlorine turbine compressor will increase the temperature of the chlorine. The high-temperature chlorine will react with the Fe in the chlorine turbine compressor equipment to generate high-valent metal chlorides. As the chlorine turbine compressor operates at high temperature for a long time, the high-temperature chlorine will cause serious damage to the chlorine turbine compressor equipment, affecting the safe operation of the chlorine turbine compressor. Therefore, the heat generated by the chlorine turbine compressor after the first and second compression must be removed in time.

[0004] To solve the above-mentioned problem of high-temperature chlorine damaging the chlorine turbine compressor, a chemical company's chlor-alkali unit uses a closed pure water circulation cooling system to cool the compressed chlorine, and the closed pure water circulation cooling system uses a circulating pump without pressure return water to drive the system water circulation. The circulating pump is a self-priming water pump. Before starting, it is necessary to remove the pump body water supply bolts, and then find a water source to fill the circulating pump cavity with water before starting. After starting, it is also necessary to adjust the circulating pump return valve several times to gradually exhaust the air in the suction pipeline to avoid cavitation of the water pump, so that the water can completely enter the pump and complete the self-priming water circulation process. It takes at least 3 to 5 minutes from starting the pump to the pressure reaching the normal working state. The maximum safety electric interlock value of the first and second stage compression inlet temperatures of the chlorine turbine compressor is 110°C, while the normal operating cooling temperature of the closed pure water circulation cooling system is 85°C to 90°C. If the circulating pump fails and stops, the entire closed pure water circulating cooling system will be unbalanced, and the first and second stage compression inlet temperatures of the chlorine turbine compressor will rise rapidly and soon reach the maximum safety interlock value of the chlorine turbine compressor inlet temperature, causing the chlorine turbine compressor to stop, which will eventually cause the entire chlor-alkali plant to shut down.

[0005] Once the circulation pump trips and stops, the existing emergency treatment measures cannot overcome the above problems. Improving the safe production rate of the chlorine turbine compressor cooling system has become a technical problem that is difficult for enterprises to overcome. Summary of the invention

[0024] The present invention is further described below in conjunction with the embodiments and drawings:

The rest can be conventional solenoid valves in the art.

[0038] As attached Figure 1 As shown, the device also includes a controller, and the chlorine turbine compressor 5, the first pressure gauge 25, the second pressure gauge 26, the first thermometer 27, the second thermometer 28, the third thermometer 29, the fourth thermometer 30, the liquid level gauge 31, the first solenoid valve 32, the second solenoid valve 33, the third solenoid valve 34, the fourth solenoid valve 35, the fifth solenoid valve 36, the sixth solenoid valve 37, the seventh solenoid valve 38, the eighth solenoid valve 39, the ninth solenoid valve 42, and the tenth solenoid valve 43 are all electrically connected to the controller.

When the first circulating pump 10 or the second circulating pump 11 fails, the emergency system of the device is started for emergency treatment. The whole operation process is simple and convenient, and can be operated by one person, overcoming the disadvantages of the original emergency system operated by multiple people and the long time of handling the emergency system. By using the device's own water source, the third solenoid valve 34 and the fourth solenoid valve 35 are closed, and water is injected into the first circulating pump 10 or the second circulating pump 11, and then the fifth solenoid valve 36, the seventh solenoid valve 37, the eighth solenoid valve 37, the eighth solenoid valve 37, the ninth solenoid valve 37, the tenth ... first solenoid pump 10 or the second circulating pump 11 is closed.

At the same time, the chilled water enters the circulating water cooler 2 through the chilled water supply pipeline 6. In the circulating water cooler 2, the chilled water exchanges heat and cools the circulating water entering from the first circulating water pipeline 8 to obtain the circulating water with the required temperature of the device.

The condensed medium in the tube side of the chlorine intermediate cooler 3 cools the chlorine in the shell side of the chlorine intermediate cooler 3 to obtain chlorine at the required temperature. The chlorine at the required temperature enters the chlorine turbine compressor 5 through the third chlorine pipeline 18 for secondary compression. The chlorine after the secondary compression enters the chlorine aftercooler 4 through the fourth chlorine pipeline 19 for heat exchange and cooling to obtain chlorine at the required temperature of the downstream process. Finally, the tube side condensed medium of the chlorine intermediate cooler 3 and the chlorine aftercooler 4 enters the circulating water pool 1 through the fifth circulating water pipeline 14 and the sixth circulating water pipeline 15.

[0043] When the first circulating pump 10 or the second circulating pump 11 fails during the above-mentioned use, chilled water is injected into the first circulating pump 10 or the second circulating pump 11 through the chilled water supply pipeline 6, the second crossing pipeline 21, the first crossing pipeline 22, the first circulating water pipeline 8, and the second circulating water pipeline 9 to complete the pump self-priming restart process.
