During the process of gas transmission and combustion, the condensed water in the gas pipeline will affect the normal operation of the gas transmission equipment and gas combustion equipment. If the condensed water cannot be discharged out of the gas transmission pipeline in time, it will cause damage to the gas transmission equipment and the operation of the gas combustion equipment. Abnormal, even endanger personal safety.
Function of gas drainer:
The function of the gas drain is to collect and drain the condensed water in the gas pipeline.
It is mainly composed of a drainer body, an anti-leakage device and a heat preservation device.
When the effective water level of the drainer decreases due to pressure fluctuations in the gas pipeline network or other reasons, resulting in gas leakage, the anti-leakage device of the gas drainer can effectively prevent the gas from leaking out and prevent gas from igniting, exploding, poisoning and other vicious accidents. occur.
common type
According to the form of heat preservation, it can be divided into steam tracing and electric tracing
Steam heating gas drainer: it relies on the steam pipe wound outside the cylinder, and steam is passed on for heat preservation in winter.
Electric heating gas drainer: it relies on the electric heating cable wound outside the cylinder, and it is energized for heat preservation in winter.
According to the size of the installation space, it can be divided into vertical and horizontal
The height of the vertical type is generally around 1200mm, and the height of the horizontal type is generally around 600mm.
The gas drainer can quickly, strictly and accurately cut off the gas that is about to leak, even when there is no water in the overpressure protection, it can still completely cut off the overpressure gas, automatically identify, without any power; the drainage is smooth, can prevent the clogging of dirt, and the cleaning cycle It can be extended by more than two times (generally 1-2 years), and can mechanically clean the dead corners of slag accumulation; especially, there is a special drainer and anti-leakage device, which can block all kinds of over-pressure gas, prevent moisture volatilization, and increase the height of water seal.
