Description

Integrated intelligent control type leakage-proof gas drainer

Technical Field

The utility model relates to a gas-liquid separation technical field, in particular to integrated intelligent control formula prevents leaking coal gas drainer.

Background

The steel production consumes a large amount of fuel, and a large amount of high-temperature flue gas as a byproduct is purified to form coal gas along with the production processes of coking, ironmaking and steelmaking. The high-temperature coal gas is continuously cooled in the process of conveying along the coal gas pipeline, saturated water in the high-temperature coal gas is condensed and separated out to form condensed water, the condensed water is converged into water flow at the bottom of the coal gas pipeline, and the condensed water moves forward along with the circulation of the coal gas. In order to ensure the safe operation of the gas pipeline, drainers are required to be installed at certain intervals to discharge gas condensate water in time. In the long-term operation process of the drainer, the gas leakage is mainly caused by three different operation conditions. Under the condition that the gas pressure is normal, the steam heat tracing or electric heat tracing drainer is adopted, and the condensate water in the drainer is evaporated after long-term operation due to overhigh heat tracing temperature, so that the height of the water seal in the drainer is reduced. If water is not supplemented in time, when the amount of condensed water in the main gas pipeline is small, gas is easy to break through a water seal to cause a gas leakage accident. Secondly, under the normal condition of the water seal height of the drainer, if the gas pressure is suddenly increased, the gas can also puncture the water seal to cause gas leakage. And thirdly, after the drainer runs for a long time, the drainer partition is corroded by coal gas to form a through hole, so that the effective water seal height of the drainer is reduced. In addition, the water level in the drainer is difficult to observe, and the water temperature and the internal gas pressure data of the drainer cannot be monitored in real time, so that the difficulty is caused for the normal operation and maintenance. The gas breakdown caused by water shortage inside the drainer, or freezing of water inside the drainer due to too low water temperature, or gas breakdown caused by too high gas pressure can be easily caused, and the drainer can not normally operate if the gas breakdown is light, and the condensate water in the main gas pipeline can not be timely discharged if the gas breakdown is heavy, thereby causing major safety accidents.
