Description

A buried gas drain

technical field

The utility model belongs to the technical field of industrial enterprise gas systems, in particular to a buried gas drainer. It is suitable for the discharge of various gas condensate water in industrial enterprises.

Background technique

Iron and steel enterprises generally have coke ovens, blast furnaces and converters. Blast furnaces, coke ovens and converters produce a large amount of by-product gas during the production process. These by-product gases are recovered and used as the main fuel for industrial furnaces in steel plants. In order to meet the requirements of use, the gas needs to be purified, stored, pressurized and mixed (part of the gas), and then transported to various users by pipelines. Due to the purified coke oven gas, blast furnace gas and converter gas, the gas often contains a small amount of mechanical water and saturated water. During the pipeline transportation process, the mechanical water and condensed water in the gas will be precipitated at any time as the temperature drops. To meet the Condensed water in the gas needs to be discharged due to transportation requirements. Because the gas contains a large amount of CO, in order to ensure the safety of the drainage process, the water seal principle is often used for drainage, because the water seal drain is the most reliable and simple drainage device. Due to the pressure in the gas, the height of the water seal needs to be higher than the maximum pressure of the gas by 5kPa or more to ensure safe drainage. Therefore, the drainer generally requires an installation height of more than 4.0m. In order to install drainers, gas pipelines and equipment are often raised, which causes a lot of waste. If the ordinary drainer is directly buried in the ground, it is not only easy to corrode, but also inconvenient to repair and maintain. This just needs a kind of gas drainer buried in the ground, not only can discharge the condensed water in the gas safely, corrosion-resistant simultaneously, overhaul and maintenance are convenient.

The working principle of the utility model: before use, the utility model is installed in the soil below the gas pipeline or equipment that needs to be drained, wherein the water inlet pipe 6 is connected with the gas pipeline or the outlet of the equipment (the valve needs to be set at the outlet, and the valve is closed) The drainpipe 9 is connected with the external drainpipe. Before putting into use, use a flexible hose to connect the external water source pipe with the water supply pipe 7, open the valve on the water supply pipe 7, and pour water into the cylinder body 2 until it is full (that is, the water outlet pipe 8 drains). , the valve on the water supply pipe 7 is closed, and the hose is removed, and a water seal is formed in the cylinder body 2 at this moment. Open the cut-off valve on the water inlet pipe 6, the condensed water in the gas pipeline or equipment is discharged into the water inlet chamber, the condensed water enters the drain chamber through the connecting pipe 5, and then is discharged into the drain pipe 9 through the water outlet pipe 8, and passes through the drain pipe 9 Discharge into external drain. The gas is sealed by the water seal in the cylinder body 2 to ensure that the gas does not leak while draining. During normal operation, it can be observed that the water outlet pipe 8 flows out of water. When the water outlet pipe 8 does not flow, it means that the cylinder body 2 is short of water. At this time, the water replenishment pipe 7 is immediately replenished. Gas leakage will occur if the water is not replenished for a long time. When the drainer has been in operation for a long time, it may be clogged or corroded. At this time, it is necessary to regularly overhaul the cylinder and so on. During maintenance, close the valve at the gas pipeline or the outlet of the equipment, remove the valve on the water inlet pipe 6, take out the cylinder body 2 etc. from the sleeve 12, carry out comprehensive inspection and maintenance on the cylinder body 2 etc. Can be put back into service.
