Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chlorine gas cooler maintenance devices and is a chlorine gas cooler protection device. Background Technique
[0002] Since the establishment of the original electrolysis workshop's No. 1 and No. 2 devices, the chlorine gas coolers have had the following problems during long-term operation:
[0003] 1) During the operation of the chlorine gas coolers used by the chlorine gas compressors of the No. 1 and No. 2 devices in the electrolysis workshop, the internal tube bundles of the chlorine gas coolers are prone to corrosion, resulting in damage to the chlorine gas cooler equipment.
[0004] 2) The circulating water system of the chlorine gas coolers used by the chlorine gas compressors of the No. 1 and No. 2 devices in the electrolysis workshop has no on-line detection equipment. When the chlorine gas cooler leaks, it cannot be detected in time. When leakage occurs, the circulating water enters the chlorine gas system through the leakage point, and at the same time, chlorine gas enters the cooling water circulating water system, resulting in damage to the chlorine gas cooler and chlorine gas compressor equipment.
[0005] 3) The chlorine gas coolers used by the chlorine gas compressors of the No. 1 and No. 2 devices in the electrolysis workshop cannot be effectively protected in the standby state. The circulating water corrodes the chlorine gas cooler, resulting in the inability of the chlorine gas cooler to be normally standby, affecting the safe and stable operation of the entire device. Summary of the Invention
[0006] The utility model provides a chlorine gas cooler protection device, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problem that the circulating water is prone to corrode the chlorine gas cooler in the standby state.
[0007] The technical solution of the utility model is realized by the following measures: A chlorine gas cooler protection device includes a chlorine gas compressor and at least two chlorine gas coolers. The chlorine gas compression inlet and outlet of the chlorine gas compressor are connected to the chlorine gas inlet and outlet of the chlorine gas cooler. The circulating water inlet of each chlorine gas cooler is connected to a circulating water inlet pipeline, and the circulating water return outlet of each chlorine gas cooler is connected to a circulating water return pipeline. Each circulating water inlet pipeline is connected to a nitrogen gas inlet pipeline, and each circulating water return pipeline is connected to a nitrogen gas outlet pipeline.
[0008] The following is a further optimization or / and improvement of the above-mentioned technical solution of the utility model:
[0009] A conductivity meter can be fixedly installed on each of the above-mentioned circulating water inlet pipelines, and a conductivity meter is fixedly installed on each circulating water return pipeline.
[0010] There are three chlorine gas coolers as described above, which may include a primary chlorine gas cooler, a secondary chlorine gas cooler, and a tertiary chlorine gas cooler; the primary chlorine gas compression inlet of the chlorine gas compressor is connected to a chlorine gas inlet pipeline, the primary chlorine gas compression outlet of the chlorine gas compressor is connected to the chlorine gas inlet of the primary chlorine gas cooler, the chlorine gas outlet of the primary chlorine gas cooler is connected to the secondary chlorine gas compression inlet of the chlorine gas compressor, the secondary chlorine gas compression outlet of the chlorine gas compressor is connected to the chlorine gas inlet of the secondary chlorine gas cooler, the chlorine gas outlet of the secondary chlorine gas cooler is connected to the tertiary chlorine gas compression inlet of the chlorine gas compressor, the tertiary chlorine gas compression outlet of the chlorine gas compressor is connected to the chlorine gas inlet of the tertiary chlorine gas cooler, and the chlorine gas outlet of the tertiary chlorine gas cooler is connected to a tertiary chlorine gas cooling pipeline.
[0011] The above-mentioned chlorine gas cooler protection device may further include a nitrogen gas main pipe, and the nitrogen gas main pipe is connected to each nitrogen gas inlet pipeline.
[0012] The above-mentioned chlorine gas cooler protection device may further include a circulating water inlet main pipe, and the circulating water inlet main pipe is connected to each circulating water inlet pipeline.
[0013] The above-mentioned chlorine gas cooler protection device may further include a circulating water return main pipe, and the circulating water return main pipe is connected to each circulating water return pipeline.
[0014] An observation sight glass may be fixedly installed on each of the above-mentioned circulating water inlet pipelines, and an observation sight glass is fixedly installed on each of the circulating water return pipelines.
[0015] The structure of the present utility model is reasonable and compact, and it is convenient to use. The arrangement of the nitrogen gas inlet pipeline and the nitrogen gas outlet pipeline can, when the chlorine gas cooler is in a standby state, drain the circulating water inside the chlorine gas cooler in time, and then fill nitrogen gas into the inside of the chlorine gas cooler through the nitrogen gas inlet pipeline to conduct nitrogen gas protection on the inside of the chlorine gas cooler, preventing the corrosion of the tubes inside the chlorine gas cooler and resulting in the inability of the chlorine gas cooler to be normally standby. When the standby chlorine gas cooler is put into use, the nitrogen gas inside the chlorine gas cooler is discharged through the nitrogen gas outlet pipeline. The setting of the conductivity meter, when the chlorine gas cooler leaks, the detected value of the conductivity meter changes, and the abnormal leakage situation of the chlorine gas cooler can be known from the detected value, prompting that the operation status of the equipment should be detected in time. It can be seen from this that the present device protects the chlorine gas cooler in the running or standby state extremely well and can avoid the occurrence of accidents of damage to the chlorine gas compressor.
