Description
Technical field
The utility model relates to the technology that cools of mining Nitrogen plant water coolant.
Background technology
The DM-600 flame-proof type membrane separation nitrogen making machine that current underground coal mine uses mainly adopts water-cooled air compressor, and this equipment has following requirement to water coolant: the cooling water source that separate unit air compressor machine requires is <27m
3/ h, if two Nitrogen plants are opened simultaneously, the about 50m of disposable water consumption
3about/h.The waste water that Nitrogen plant produces all enters mine sump, adds Mine Drainage System pressure.
Because Nitrogen plant cooling water drainage water temp can reach 80 DEG C, the wastewater temperature of generation is higher, after flowing into underworkings internal drainage ditch, can increase mine inlet temperature more than 2 DEG C slowly because dispelling the heat, and underground construction place temperature is raised, and operating environment worsens.
Utility model content
For reducing Nitrogen plant water coolant water consumption, reducing mine drainage expense and water discharge pressure, the utility model proposes a kind of Nitrogen plant cooling water temperature recycling system.
Technical scheme is, a kind of Nitrogen plant cooling water temperature cyclic utilization system, is characterized in that:
1, can one be set up be not less than 90m in the tunnel of independent ventilation near Nitrogen plant room
3pond, build waterwall in pond, pond is divided into 30m by waterwall
3water reservoir and 60m
3cooling pond; Stay limbers bottom waterwall, utilize the characteristic that the hot lower floor in water temperature upper strata is cool, make the low temperature water in cooling pond flow into water reservoir;
2, water level sensor and moisturizing electrically operated valve are installed in water reservoir, according to water reservoir water level by controller Long-distance Control moisturizing electrically operated valve, realize water reservoir automatic water supplement; Mounting temperature sensor and draining electrically operated valve in water reservoir, by controller Long-distance Control draining electrically operated valve during water reservoir temperature height, realize automatic-discharging hot water, make the temperature of water coolant control in allowed band;
3, on cooling pond, set up cooling tower, utilize the hot water of dash to cooling tower to lower the temperature; In cooling basin bottom, air line is installed simultaneously, utilizes pressure wind to stir water pool inner water, fast cooling;
4, near water reservoir, the lift 50 meters of 5.5kw, the wet-pit two of flow 20m/h are installed, a job, one for subsequent use, the water meeting Nitrogen plant chiller temperature is squeezed into Nitrogen plant water cooler by wet-pit, hot wastewater after the heat exchange of Nitrogen plant water cooler enters cooling tower by pipeline, naturally get back to cooling pond after cooling, make Nitrogen plant water coolant form the recycle system.
The utility model achieves recycling of Nitrogen plant water coolant, improves resource utilization, has saved effluent cost.Owing to utilizing dash to lower the temperature to cooling tower hot water, heat is rejected in the outer air of well very soon, and underground construction place temperature can not be raised, and operating environment is good.
