Description

Compressed air pipeline drainage device

Technical Field

The utility model belongs to the technical field of compressed air pipeline structures, and particularly relates to a compressed air pipeline drainage device.

Background

In the thermal power generation system, more pipeline valves are used as pneumatic valves, and the pneumatic sources of the pneumatic valves are compressed air, but because of more moisture in the air, condensed water is separated out from the pipeline along with the change of pressure and temperature, if the water cannot be drained in time, pneumatic control elements of terminal equipment and related instrument instrumentation lamps are easily damaged, equipment failure and high maintenance cost are caused, and the production efficiency and the stability of product quality are reduced, so that serious economic loss is caused.

At present, an air dryer and a compressed air tank are additionally arranged behind a compressed air machine in the market to solve the problems, and although the air dryer and the compressed air tank can play a certain role, 100% of water cannot be removed, a small amount of air-shaped water is easy to condense on a pipeline, and particularly, the phenomenon of water vapor condensation is easy to occur at dead corners and lower positions of the pipeline. At the same time, the compressed air pipe is partially buried in the ground, which makes drainage difficult. Therefore, how to solve the problem of water accumulation in the compressed air pipeline and meet the requirements of industrial application is a hotspot which is constantly researched in the industry.

Disclosure of Invention

Aiming at the technical problems, the utility model provides a compressed air pipeline drainage device which solves the drainage discharging problem of the existing compressed air pipeline and can effectively discharge accumulated water in the compressed air pipeline.

The utility model provides a compressed air pipeline drainage device which comprises a compressed air pipeline, a water collecting cavity, a communicating pipe, a drainage cavity, a deflation pipe, a U-shaped pipe and a drainage pipe, wherein the water collecting cavity is arranged below the compressed air pipeline, the drainage cavity is arranged below the water collecting cavity, the communicating pipe is respectively communicated with the water collecting cavity and the drainage cavity, the bottom of the drainage cavity is of a funnel-shaped structure, one end of the U-shaped pipe is connected with the bottom opening of the funnel-shaped structure, a hollow rubber ball is arranged in the drainage cavity, the diameter of the hollow rubber ball is larger than the inner diameter of the bottom opening of the funnel-shaped structure, the other end of the U-shaped pipe is connected with the drainage pipe, the drainage pipe extends to the upper side of the compressed air pipeline, the deflation pipe is connected to the upper side wall of the drainage cavity, a first control valve is arranged on the communicating pipe, and a second control valve is arranged on the deflation pipe.

Further, a third control valve is arranged on the compressed air pipeline.

Further, a filter screen is arranged in the compressed air pipeline.

When the compressed air pipeline drainage device discharges accumulated water, the accumulated water flows into the drainage cavity through the water collecting cavity and the communicating pipe, and the accumulated water in the drainage cavity can be pressed out through the drainage pipe under the action of pressure force due to the fact that the compressed air pipeline has higher pressure, and the drainage of the compressed air pipeline buried underground is facilitated by arranging the U-shaped pipe to facilitate the upward drainage of the accumulated water; when the water level in the drainage cavity is too low, the hollow rubber ball seals the bottom opening of the funnel-shaped structure under the action of air pressure, so that air leakage is avoided, and manual control is not needed. On the other hand, when the drainage cavity needs to be cleaned, the first control valve can be closed, the second control valve is opened, cleaning water is injected into the drainage cavity through the drainage pipe, and back flushing is carried out on the drainage cavity, so that the influence of dirt in the drainage cavity on the operation of the device is avoided.
