Problems solved by technology

Existing problems include: the effect of the ventilation system becomes worse with the increase of the working depth; the cost of workers’ cooling clothes is high, and the operation process is inconvenient; the underground refrigerator has difficulty in heat dissipation, and the use of air as the heat dissipation medium leads to poor cooling effect and high operating costs, etc. question
Fluid-induced vibration can cause severe noise and damage to the heat transfer tube bundle, and fouling on the surface of the heat transfer tube bundle can cause huge energy and resource losses

Embodiment Construction

[0040] figure 1 A schematic diagram of the overall structure of a thermal system for deep mining is shown. Such as figure 1As shown, the thermal system of deep well mining includes three parts, which are the return air shaft part, the underground chamber part and the working face (mining area) part, in which the return air shaft part is equipped with a cooling tower 8, and the underground chamber part is equipped with an evaporator 2 , an expansion valve 3, a compressor 1 and a condenser 4, and the air cooler 6 is arranged on the working surface. The air cooler 6 is used to cool downhole air, and the evaporator 2, expansion valve 3, compressor 1, and condenser 4 constitute a refrigeration system; the cooling tower 8 and the condenser 4 constitute a circulation pipeline, and the air return shaft After the air in the cooling tower 8 exchanges heat with water, the water enters the condenser 4 through the pipeline, and exchanges heat with the refrigerant in the condenser 4. Afte...

Abstract

The invention provides a deep well mining refrigerating system capable of controlling noise. When the vibrating noise of a heat exchange component is too large, the valve opening degree of a by-pass valve is controlled to be reduced, and the opening degree of a main way valve is enlarged; and if the vibrating noise is reduced to a certain degree, the valve opening degree of the by-pass valve is controlled to be enlarged, and the opening degree of the main way valve is reduced. By means of the design, it is avoided that vibration generates very large noise, and better effects of intensifying heat transfer and dirt removing are achieved.

Description

[0001] This application is a divisional application for April 9, 2019, application number 2019102780918, and the title of the invention "a spiral-wound heat exchanger and deep well thermal system". technical field [0002] The invention relates to the technical field of heat exchangers, in particular to a thermal system for deep well mining. Background technique [0003] In the process of deep mine mining, the problem of deterioration of underground thermal environment is very prominent. As the mining depth of the mine increases, after entering the deep part, the working face of the mine begins to be affected by high temperature, which not only restricts the safe production and construction of the mine, but also threatens the health of the miners. my country's "Safety Regulations for Metal and Nonmetal Mine" stipulates that the air temperature of the mining face of the production mine shall not exceed 26°C, and the air temperature of the electromechanical equipment chamber s...
