Problems solved by technology

[0002] At present, the severe cold climate in the alpine region has brought great difficulties to the construction and construction of mines
The main difficulty is that air picks and pneumatic rock drills are mainly used to drill during mine freezing and drilling in winter. Due to the humidity of the compressed air used as the source of drilling air, condensation occurs in the compressed air pipeline, which makes the compressed air pipeline The condensed water inside is easy to freeze, which brings inconvenience to underground construction

Embodiment Construction

[0013] As shown in the figure, the anti-freezing device of the present invention includes an alcohol tank 1. A quantitative adjustment valve 2 is installed at the bottom of the alcohol tank 1. The quantitative adjustment valve 2 is connected with an air needle dropper 3, and the air needle drop tube 3 is inserted into the air pressure. Tube 4.

[0014] When in use, the antifreeze device of the present invention is installed upstream of the compressed air pipeline, and a condensate collector 5 is installed downstream of the compressed air pipeline. When the air is supplied with pressure, open the quantitative regulating valve 2, and the alcohol stored in the alcohol tank 1 enters the air needle dropper 3 inserted into the pressure air pipe 4 through the quantitative regulating valve 2, and the air needle opens the drip hole under the driving of the air flow. It sprays out and diffuses into the humid compressed air. As the ambient temperature of the downstream pipeline decreases, t...

Abstract

The invention discloses a severe cold area compressed air antifreezing method and an antifreezing device thereof. In the method, when compressed air is transported, pure alcohol is sprayed at the upstream of a transport pipeline, and the downstream of the transport pipeline is connected in series with a condensed water collector. In the antifreezing device, a quantitative regulation valve is installed at the bottom of an alcohol tank, and a wind needle type dropper is connected to the quantitative regulation valve and is inserted into a compressed air pipeline. The method utilizes a principle that the freezing point of alcoholic solution is lower than the freezing point of water to spray the pure alcohol into humid compressed air, the humidity in the compressed air gradually achieves a dewpoint to separate out the moisture, the moisture forms low concentration alcoholic solution with the alcohol together, and the low concentration alcoholic solution enters the condensed water collector and is not easy to freeze because the freezing point of the alcoholic solution is low, thereby reaching the antifreezing purpose.

Description

Technical field [0001] The invention relates to the technical field of compressed air power for coal mines. Background technique [0002] At present, the severely cold climate in the alpine region has brought huge difficulties to the construction and construction of the mine. The main difficulty is that air picks and air-driven rock drills are mainly used during mine freezing and sinking during winter construction. Because the compressed air used as the source of the drilling air is humid, condensation occurs in the air pressure pipeline, which makes the air pressure pipeline The condensed water inside is easy to freeze, which brings inconvenience to underground construction. Summary of the invention [0003] The purpose of the present invention is to provide an antifreeze method for preventing the freezing of compressed air in view of the above situation [0004] The present invention also provides an antifreeze device for implementing the above method. [0005] An antifreeze meth...
