Description
Technical Field
The utility model relates to a synthetic gas leakage detection system.
Background
In the process of cooling the synthesis gas, the condenser is difficult to guarantee sealing performance all the time due to cold and hot expansion, water hammer washing, pipe vibration and the like, and a small amount of synthesis gas unexpectedly leaks into a cooling medium phase. At present, after the condenser leaks slightly, operators can hardly find the condenser, even if a concentration analyzer is arranged, high concentration can be caused due to continuous accumulation of a small amount of synthesis gas, and the concentration analyzer is not reasonable in taking a switching-off measure when detecting the high concentration. If the on-line detector is not stopped, the on-line detector always gives an alarm to take no measures and loses the significance of the arrangement, and the concentration analyzer judges a great amount of synthesis gas leakage due to high concentration. Therefore, it is particularly necessary to provide an online detection and treatment process for syngas leakage, which can not only determine the gas leakage degree, but also perform online timely treatment.

Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in figure 1, the synthesis gas leakage detection system comprises a nitrogen inlet 1, a medium inlet 2, a cooling water outlet 3, a cooling water inlet 4, an electric control ball valve 5, a ball valve 6, a condenser 7, a pressure gauge 8, a thermometer 9, a gas-liquid separation tank 10, a liquid level meter 11, a flow meter 12, a liquid discharge low-pressure pipeline 13 and an exhaust low-pressure pipeline 14.
A synthetic gas leakage detection system comprises a medium inlet 2 and a nitrogen inlet 1, wherein the medium inlet 2 and the nitrogen inlet 1 are connected with a condenser pipe of a condenser 7, the condenser 7 comprises the condenser pipe and a shell, cooling water is filled between the condenser pipe and the shell, a cooling water inlet 4 and a cooling water outlet 3 are arranged on the shell, the condenser 7 is connected with a gas-liquid separation tank 10, a pressure gauge 8 and a temperature gauge 9 are arranged on a pipeline between the condenser 7 and the gas-liquid separation tank 10, the upper part of the gas-liquid separation tank 10 is gas, the top of the gas-liquid separation tank 10 is connected with an exhaust low-pressure pipeline 14, the lower part of the gas-liquid separation tank 10 is liquid, the bottom of the gas-liquid separation tank 10 is connected with a liquid discharge low-pressure pipeline 13, a liquid level meter 11 is arranged in the gas-liquid separation tank 10, a sampling point is arranged on the gas-liquid discharge low-pressure pipeline 14, a flow meter 12, be equipped with ball valve 6 and automatically controlled ball valve 5 on the pipeline between medium import 2 and the condenser 7, be equipped with ball valve 6 between cooling water outlet 3 and the condenser 7, be equipped with ball valve 6 between cooling water import 4 and the condenser 7, flowing back low pressure pipeline 13 on be equipped with automatically controlled ball valve 5 return circuit.
The system principle is to detect whether the syngas leaks by measuring the liquid level in the gas-liquid separation tank 10. When leakage occurs, the conditions of system pressure rise and liquid level drop are caused because the solubility of the synthetic gas in the cooling water is limited, and the alarm can be given when the liquid level is low. At this time, sampling analysis is carried out immediately from a sampling point at the gas phase outlet of the separation tank. Quantitative analysis of syngas leakage can be achieved by flow meter and knock out pot level measurements. After the detection was completed, the apparatus was flushed with nitrogen gas to discharge the residual gas.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
