Abstract
The invention relates to a method for removing underground fog. The method includes that fans and air coolers are mounted on underground roadways in the heavy fog, the fans are connected with the air coolers by air ducts, cold-water supply pipes and cold-water return pipes are connected onto the air coolers, and gate valves, filters, temperature gauges and pressure gauges are respectively mounted on the cold-water supply pipes and the cold-water return pipes; the gate valves on the cold-water supply pipes and the cold-water return pipes are opened, so that cold-water can continuously flow in the air coolers, the fans are started, partial hot air is pushed into the air coolers by the aid of the fans, the partial hot air in the air coolers is cooled and dehumidified and then flows into the underground roadways, the partial hot air and uncooled hot air are mixed with each other to obtain hot and cold mixed air, water vapor in the hot air can be condensed when the hot air and the cold air are about to be mixed with each other and the hot air is suddenly in contact with the cold air, fog can be formed, water drop further can be formed, the fog can be gradually reduced when the air flows forwardly, and fogless cold air can be formed. The method has the advantage that underground working environments can be greatly improved by the aid of the method.
Description
Technical field
The present invention relates to a kind of underworkings defogging method, be specially a kind of cold water cooling air that adopts to reach the defogging method of demist object.
Background technology
In the coal reserves that China is verified, the coal reserves of 1000 ~ 2000m depths accounts for 53.2% of gross reserves, therefore the mining depth of mine is in continuous increase, along with the continuous increase of the mining depth of mine, mine job site working environment is more and more warmmer, and instant heating evil is more and more serious.There is the airflow temperature of the getting working face of multipair mine in China more than 30 DEG C according to statistics, and return aircourse is all dense fog, produces a very large impact shaft production.
At present, the demist of down-hole tunnel do not have ready-made method.
Summary of the invention
The object of the invention is, for above-mentioned present situation, to aim to provide a kind of defogging method.
The condition that mist is formed: one is cooling, and two is humidifications, increases moisture content.
The formation (see figure 1) of mist: hot air 2, enter underworkings 1, along with hot air 2 is gone ahead, hot air 2 cools gradually, and hot air 2 just becomes supersaturated air 3, when steam contained in air is more than the saturation vapour amount under uniform temperature condition, unnecessary steam will condense out, and combine with small dust granule in air when abundant moisture, hydrone itself also can bond mutually simultaneously, just become little water droplet, start to form mist.Supersaturated air 3 cools further, will form thick fog 4, affects downhole safety and produces.
The implementation of object of the present invention is (see figure 2): provided with fan 7 and air cooler 9 on underworkings 1, be connected with air duct 8 between fan 7 with air cooler 9; Air cooler 9 connects cold water supplying pipe 10 and cold-water return pipe 15, connect on cold water supplying pipe 10 and cold-water return pipe 15 and gate valve 11, strainer 12, thermometer 13 and pressure meter 14 are installed respectively.Open the gate valve 11 on cold water supplying pipe 10 and cold-water return pipe 15, cold water is allowed not arrhea in air cooler 9 dynamic, start fan 7, part hot blast 2 is pressed into air cooler 9 by fan 7, part hot blast 2 is in air cooler 9 after cool-down dehumidification, enter underworkings 1, mix with the hot blast 2 not having to cool, form the cold temperature of heat and close air 5, during hot cold air mixing, hot air runs into cold air suddenly, and the steam in hot air will condense out, and forms mist, further formation water droplet, when air is gone ahead, mist can diminish gradually, can form the cold air 6 without mist.
The present invention has following features:
A, removing dense fog, staff's sight line is good;
B, reduction tunnel temperature, staff's working environment is good;
In C, air, water capacity reduces, temperature reduces, and increases electromechanical equipment application life.
Accompanying drawing explanation
Fig. 1 is that underworkings mist forms schematic diagram; Fig. 2 is that schematic diagram is arranged in underworkings demist.
detailed description of the invention
With reference to accompanying drawing, the present invention by underworkings 1, hot air 2, supersaturated air 3, thick fog 4, hot cold mixing air 5, cold air 6, fan 7, air duct 8, air cooler 9, cold water supplying pipe 10, gate valve 11, strainer 12, thermometer 13, pressure meter 14, cold-water return pipe 15 forms.
When the present invention works, open the gate valve 11 on cold water supplying pipe 10 and cold-water return pipe 15, cold water is allowed not arrhea in air cooler 9 dynamic, start fan 7, part hot blast 2 is pressed into air cooler 9 by fan 7, and part hot blast 2 after cool-down dehumidification, enters underworkings 1 in air cooler 9, mix with the hot blast 2 not having to cool, form the cold temperature of heat and close air 5, during hot cold air mixing, hot air runs into cold air suddenly, steam in hot air will condense out, form mist, form water droplet further, when air is gone ahead, mist can diminish, and can form the cold air 6 without mist.
Claims (2)
1. a down-hole defogging method, is characterized in that provided with fan and air cooler on dense fog tunnel, down-hole, is connected between fan with air cooler with air duct; Air cooler connects cold water supplying pipe and cold-water return pipe.
2. cold water supplying pipe and cold-water return pipe to be pretended closing valve and configuration component.
