Problems solved by technology

The water system of the direct contact mine recooler is open, directly in contact with the air, and the heat exchange effect is greatly enhanced, but the water is easily polluted, which is not conducive to recycling, and requires a large amount of water. After the spray water is used, it needs to be treated after water treatment. Recycling, in the current situation, this kind of mine recooler has not been applied in China

Embodiment Construction

[0028] figure 1 is a schematic diagram of the structure of the present invention, figure 2 for figure 1 A-A cross-sectional view, as shown in the figure: the mine recooler of this embodiment includes a filter 1, a mine counter-rotating axial flow local fan 2, an air inlet 3, a heat exchange chamber 4, an air outlet 5 and a set of The heat exchange coil 6 used for heat exchange between cooling water and air in the heat exchange chamber 4. The heat exchange coil is made of φ16×1mm copper tubes, with 50 surface tubes and 37 rows, bent into a serpentine shape, and the air flow is uniform. It flows through the heat exchange coil, the contact area is large, and the heat exchange effect is good. Connected in sequence, the mine recooler also includes a spray device, the spray device includes two spray water pipes 7 and 12 atomizing nozzles 8 arranged on the spray water pipes 7, the atomizing nozzles 8 It is located in the heat exchange chamber 4, and its injection port faces the h...

Abstract

The invention discloses a recooler for mines, comprising a filter, a local ventilator for mines, an air inlet, a heat transfer room, an air outlet and a heat transfer coil which is arranged in the heat transfer room and is used for transferring heat of cooling water and air, wherein the filter, the local ventilator for mines, the air inlet, the heat transfer room and the air outlet are successively communicated from front to back. The recooler for mines also comprises a sprinkler. The sprinkler comprises a sprinkling water tube and at least two atomizing nozzles arranged on the sprinkling water tube; and the atomizing nozzles are arranged in the heat transfer room, and the injection orifices thereof face to the heat transfer coil. The recooler for mines adopts the light tube type, also has two modes of sensible heat transfer and latent heat transfer and has high heat transfer efficiency; meanwhile, the recooler for mines can be disassembled for transportation and installation; and according to the refrigerating capacity, the quantity of the heat transfer room is determined. The recooler for mines is convenient and flexible to use, can bear pressure more than 4MPa, has the functionof automatic cleaning and has good dust-proof, antiseptic and thermal insulation properties.

Description

technical field [0001] The invention relates to a regenerative device for a mine or tunnel cooling system, in particular to a mine regenerator. Background technique [0002] With the increase of mine mining depth and the influence of heat sources such as high temperature surrounding rock heat dissipation, air self-compression heat, mechanical equipment heat dissipation, and oxidation heat, more and more mines have heat damage. Heat damage is one of the factors restricting safe production in mines, which not only endangers the health of miners, but also reduces labor productivity and affects safe production and economic benefits. my country's "Coal Mine Safety Regulations" clearly stipulates: "The air temperature of the mining face of the production mine shall not exceed 26 °C, and the air temperature of the electromechanical chamber shall not exceed 30 °C; when the air temperature of the mining face exceeds 30 °C, the air temperature of the electromechanical chamber shall ex...
