Mining membrane type high-low pressure conversion device

Abstract

The invention discloses a mining membrane type high-low pressure conversion device, and belongs to the technical field of mine refrigeration machines. The mining membrane type high-low pressure conversion device comprises a refrigeration station arranged outside a mine and a radiator arranged in the mine, and further comprises a first container and a second container which are arranged in the mine, a first elastic membrane is arranged in the first container, a second elastic membrane is arranged in the second container, the first container and the second container are divided by the first elastic membrane and the second elastic membrane respectively into the cold water sides and the hot water sides, the cold water sides of the first container and the second container are communicated with a water outlet of the refrigeration station and a water inlet of the radiator respectively, and the hot water sides of the first container and the second container are communicated with a water return opening of the refrigeration station and a water outlet of the radiator respectively. As only membrane elastic deformation in the containers is adopted in the high-low pressure conversion process for transferring, the cold losses are small, accurate control is carried out, the working condition of the refrigeration station is matched with the actual refrigeration load, the operation energy consumption of the refrigeration station is reduced, and the temperature of a local area in the mine can be efficiently reduced.

Description

technical field

[0001] The invention relates to the technical field of mine refrigeration machinery, in particular to a high-low pressure conversion device for mine cold water and hot water, which uses high-pressure cold water to push low-pressure hot water to the ground. Background technique

[0002] As the depth of mine mining increases, when the cold water of the centralized refrigeration unit on the mine ground is transported underground, the static pressure of the water has far exceeded the pressure range of the end radiator. This high-low conversion device can reduce the pressure of high-pressure cold water. To be able to meet the requirements of the radiator, and the cooling loss is extremely small. This device utilizes the principle of U-shaped tubes. The water inlet pipe and the return water pipe form a U-shaped pipe, so that high-pressure cold water can push low-pressure hot water to the ground, thereby realizing energy exchange, and there is no need to use pumps t...

Embodiment Construction

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0022] As shown in the figure, the thin-film type high-low pressure conversion device for mining in this embodiment includes a refrigeration station 1 arranged outside the mine and a radiator 2 arranged in the mine. The device 2 absorbs the heat in the local area of ​​the mine and enters the circulating water. It also includes the container I3 and the container II4 arranged in the mine. The elastic film I is arranged in the container I3, and the elastic film I separates the container I3 into a cold water side and a hot water side. side, the cold water side of the container I3 communicates with the water outlet 5 of the refrigeration station 1 and the water inlet 8 of t...
