For ease of understanding, be described further below in conjunction with drawings and the specific embodiments.
Embodiment
As shown in Figure 1, present embodiment provides a kind of deep-well hot working face cold wind cooling system, and this system specifically comprises:
Crossheading 6 air intake vent places are provided with air door 1 on the work plane of deep-well, last crossheading 6 one sides are provided with the special-purpose tunnel 2 of cooling, the air outlet 4 in special-purpose tunnel of lowering the temperature is communicated with last crossheading 6, and cooling end-equipment 5 is set in the special-purpose tunnel 2 that lowers the temperature, and the air intake in the special-purpose tunnel that lowers the temperature 8 is gone up a hill with air intake and is connected.
Wherein, the cooling end-equipment described in the said system adopts the modular cooler, and as shown in Figure 2, this modular cooler comprises: water inlet manifold 26, total return pipe 21, frame and at least one cooling structure module 28; Cooling structure module 28 is arranged on the frame, and the water inlet pipe 10 of cooling structure module 28 is connected with water inlet manifold 26, and the return pipe 9 of cooling structure module 28 is connected with total return pipe 21; Position corresponding with cooling structure module 28 on the frame is provided with air intake, and the air intake of this modular cooler is corresponding with the air intake in the special-purpose tunnel of cooling.
In the reality, described modular cooler comprises a plurality of cooling structure modules, and the water inlet pipe of each cooling structure module all is connected with water inlet manifold, and the return pipe of each cooling structure module all is connected with total return pipe.The cooler that is the integral body of formation that is connected in parallel between described a plurality of cooling structure module by water inlet manifold and total return pipe, in the use, the water inlet manifold 26 of this modular cooler and total return pipe 21 are connected with circulation cooling system in the deep-well by pipeline.
Above-mentioned modular cooler, water inlet manifold, total return pipe form the closed cycle of primary side water body with each cooling module that is connected, and are formed the open circuit circulation of secondary side gas, liquid interchange of heat between each cooling module by the wind that the air intake A on the frame enters.During concrete work, primary side participates in by the formed circulation down of water body closed cycle, secondary side is because the distinguished and admirable intervention from air intake in tunnel can be finished the heat exchange effect of chilled water circulating water body and hot blast, and promptly secondary side has participated in the open circuit circulation of gas-liquid two-phase heat exchange.This cooler like this can mate the requirement of cooling work plane refrigeration duty by the quantity of cooling structure module, makes module design, the simplification of cooler; Can control the cold that it provides by the quantity that increases or reduce assembling cooling structure module according to the continuous variation of cooling work plane refrigeration duty demand, more effectively satisfy on-the-spot condition complicated and changeable; This cooler can move with the continuous propelling of work plane, thereby effective cold is provided, the refrigeration duty requirement complicated and changeable of easier satisfied on-the-spot cooling work plane.
In actual applications, a plurality of cooling structure modules of forming the cooling end-equipment are evenly distributed in the special-purpose tunnel of cooling, as can be as shown in fig. 1, make that spacing 800cm evenly arranges between the cooling structure module, the air that assurance is passed through reaches heat exchange effect preferably, makes from the pure cold wind for low temperature, low humidity of the special-purpose tunnel air outlet output of lowering the temperature.
It is a kind of based on the above-mentioned dark also cool-down method of hot working face cold wind cooling system that present embodiment also provides, and this method specifically comprises:
