Problems solved by technology

[0004] The main disadvantage of the existing product is that although there is gas condensate flowing into the drainer, the amount of liquid evaporation is large, and there must be enough liquid level in the drainer cylinder to seal the gas, and the drainer is made of steel, and the liquid The level cannot be seen. For the safety of gas, it is necessary to supply water to the drainer all the time to ensure that there is always water flowing out of the drainpipe to ensure the liquid level of the drainer, resulting in a lot of waste of water.

Embodiment Construction

[0016] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, a liquid level port view type water seal drainage device of the present invention includes a drainage cylinder 1 , a gas downcomer 3 , a water supply pipe 4 , a drain pipe 5 and a liquid level display pipe 6 . The gas downpipe 3 is connected to the gas pipeline 2 through the water collecting funnel 7, and the first gate valve 8 is set on the gas downpipe 3 near the water collecting funnel 7, and the second gate valve 9 is set near the drainage cylinder 1. The gas downpipe 3 needs to be inserted into the liquid in the drainage cylinder 1, and the hydrostatic pressure P at the mouth of the gas downpipe 3 is greater than the pressure in the gas pipeline 2, where P=ρgh, h is the gas downpipe 3 inserted into the drainage cylinder The depth of the liquid level in the body 1 ensures that the liquid level can seal th...

Abstract

The invention discloses a liquid level port view type water seal drainage device, which comprises a drainage cylinder body, a gas downcomer inserted into the drainage cylinder body and connected with a gas pipeline, and a water supply pipe, a drain pipe and a liquid drain pipe located on the drainage cylinder body. bit display tube. The present invention utilizes the liquid level display tube to clearly observe the water level in the drainage cylinder at any time, and on the premise of ensuring the liquid level in the drainage cylinder, it can minimize the waste of water resources; moreover, the structure of the present invention is simple and reasonable, Easy to operate and easy to apply and promote.

Description

technical field [0001] The invention relates to a drainage device, in particular to a liquid level port view type water seal drainage device. Background technique [0002] The gas pipeline transports the gas saturated with water vapor. During the pipeline transportation process, the temperature of the gas decreases due to the heat dissipation of the pipe wall, and the part of the water vapor that was originally saturated in the gas is condensed to form a condensate. If the condensate in the gas pipeline is not discharged, it will gradually accumulate in the pipeline, which will greatly affect the safe operation of the gas pipeline. Therefore, a water seal drainer is used to ensure the continuous and safe discharge of the gas condensate. [0003] A small gas pipeline is connected to the bottom of the gas pipeline, and the small gas pipeline is inserted into the bottom of the water-sealed drainer (steel cylinder-shaped water container), and the static pressure generated at the...
