Description

Anti-leakage coal gas drainer

Technical Field

The utility model relates to a gas piping equipment technical field specifically is a prevent leaking coal gas drainer.

Background

A gas drainer is a device applied to a gas pipeline. The coal gas contains moisture as common air, and the moisture is in a gas state at high temperature and is condensed into liquid water at the temperature below the dew point. The gas has certain pressure in the pipeline, and when the gas releases pressure, the gas can absorb heat to reduce the temperature and generate a condensation effect, and the condensation effect can condense water in the gas into water drops. Because the water flows to the lower part, the water accumulation phenomenon can occur at the lowest end of the gas pipeline. When the water accumulation is serious, the flow and the pressure of the coal gas can be even influenced. In order to solve the problem, in the prior art, a lowest port is often artificially arranged in a gas pipeline system, so that accumulated water in a pipeline is accumulated, and then the accumulated water is collected and pumped out by utilizing a device. The function of the gas drainer is divided according to the structure of the drainer, and the gas drainer is generally in a cylindrical shape, a rectangular shape, a square shape and the like. The drainer can be divided into a single-cavity type, a double-cavity type and a multi-cavity type according to the difference of the gas pressure in the pipeline.

The traditional water-sealed gas drainer is characterized in that a drain pipe at the lower part of a gas pipeline extends into a drainer cylinder body and is sealed by water with a certain height, so that gas cannot escape, and condensed water in the gas pipeline can be automatically drained. Under the condition of normal pressure of coal gas, the drainer can safely operate, but when the pressure of the coal gas fluctuates greatly, high pressure occurs, water loss caused by water level reduction of the drainer or other reasons is caused, water is not enough to seal the coal gas, and finally, a large amount of coal gas is leaked, so that accidents occur.
