Do you know about gas drain?

Product Information

Gas is a by-product of ironmaking, steelmaking, and coking, and it is also the main hot material for heating metallurgical furnaces. During the gas transportation and combustion process, the condensed water in the gas pipeline will affect the normal operation of the gas transportation 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, abnormal operation of the gas combustion equipment, and even endanger personal safety. Therefore, configuring a gas drainer plays an important role in the safe transportation of gas.

Working Principle

The anti-leakage gas drain uses intermittent drainage during operation. The water is discharged through a pontoon that rises and falls along the guide rail and is isolated from the outside atmosphere.

The condensed water from the gas pipe network enters the gas drain through the down pipe, and then reaches the anti-leakage device. When the water level in the cylinder rises to a certain position, the gravity of the buoy is less than the buoyancy, the buoy floats, and the condensed water is discharged through the water outlet.

After the condensed water is discharged, the water level in the cylinder drops, the gravity of the buoy is greater than the buoyancy, and the buoy descends and is isolated from the outside atmosphere through a conical gasket.

Even if the pressure of the gas pipeline network is too high and exceeds or cannot reach the effective water seal height of the drainer, the leakage prevention device can effectively isolate the gas from the outside world through the buoy and conical gasket, thereby avoiding gas leakage.

Installation Precautions

1. It must be installed vertically and not tilted to ensure that the drainer works reliably. The on-site gas pipeline is connected to the gas drain inlet pipe, and a sealing gasket should be used at the flange connection to ensure a tight seal and no gas leakage.

2. The drainage pipe should be connected to the nearby sewer. Condensed water should not be discharged directly under the equipment foundation. There should be guardrails and warning signs around to prevent accidents such as collision and leakage.

3. Before use, the gas drainer must be filled with water. When adding water, first open the exhaust valve, and then use the water filling port to add water to the gas drainer. When water flows out from the condensate drain pipe, the water addition is completed. After the water addition is completed, the exhaust valve must be closed to prevent gas leakage!
