Synthesis gas leakage detection system

Abstract

The invention discloses a synthetic gas leakage detection system, which comprises a medium inlet and a nitrogen inlet. The medium inlet and the nitrogen inlet are both connected with a condenser pipeof a condenser, the condenser comprises a condenser pipe and a shell, the space between the condenser pipe and the shell is filled with cooling water, the shell is provided with a cooling water inletand a cooling water outlet, the condenser is connected with a gas-liquid separation tank, a pressure gauge and a thermometer are arranged on a pipeline between the condenser and the gas-liquid separation tank, gas is arranged at the upper part of the gas-liquid separation tank, the top of the gas-liquid separation tank is connected with an exhaust low-pressure pipeline, liquid is arranged at the lower part of the gas-liquid separation tank, the bottom of the gas-liquid separation tank is connected with a liquid discharge low-pressure pipeline, a liquid level meter is arranged in the gas-liquidseparation tank, a sampling point is arranged on the gas-liquid separation tank, and a flow meter is arranged on the liquid discharge low-pressure pipeline. The system is ingenious in design, whethersynthesis gas leaks or not can be visually reflected through the liquid level meter, sampling analysis can be conducted at a sampling point, meanwhile, a nitrogen flushing device is arranged, and thesystem is safe, efficient, convenient to use and reliable.

Description

technical field [0001] The invention relates to a synthesis gas leakage detection system. Background technique [0002] During the cooling process of the syngas, due to thermal expansion of the condenser, water impact erosion, pipe vibration and other reasons, it is difficult to ensure the tightness of the condenser all the time, and a small amount of syngas will leak into the cooling medium phase unexpectedly. At present, after a small amount of leakage occurs in the condenser, it is difficult for the operator to find out, and even if a concentration analyzer is installed, the continuous accumulation of a small amount of syngas will lead to high concentrations. Very reasonable. If the machine is shut down for maintenance due to a small amount of leakage, it will cause huge economic losses. If the machine is not shut down, the on-line detector will always alarm without taking measures and lose the meaning of its setting. The concentration analyzer will not be careful in jud...

[0002] During the cooling process of the syngas, due to thermal expansion of the condenser, water impact scouring, pipe vibration and other reasons, it is difficult to ensure the tightness of the condenser all the time, and a small amount of syngas will leak into the cooling medium phase unexpectedly

At present, after a small amount of leakage occurs in the condenser, it is difficult for the operator to find out, and even if a concentration analyzer is installed, the continuous accumulation of a small amount of syngas will lead to high concentrations. very reasonable

If the machine is shut down for maintenance due to a small amount of leakage, it will cause huge economic losses. If the machine is not shut down, the on-line detector will always alarm without taking measures and lose the meaning of its setting. The concentration analyzer will not be meticulous in judging a large amount of syngas leakage due to high concentration
