This refrigerating system sets up on the air pipeline, carry, convenient operation, simple structure.
Description
Technical field
The utility model relates to construction system, in particular to constructing tunnel ventilation refrigeration system.
Background technology
There are Climatic regionalization tunnel and low warm harmful tunnel two class in heat evil tunnel, Climatic regionalization tunnel is owing in construction, too high or that various thermal source discharges in the construction process heat of country rock temperature causes construction environment temperature too high, low warm harmful tunnel refers to that country rock original temperature is too low or too low in extremely frigid zones tunnel environment temperature, when inlet temperature is lower than 20 DEG C, it is necessary to carrying out preheating in hole. In these two kinds of tunnel environment situations so that difficulty of construction is bigger than normal, and security risk is big.
For Climatic regionalization tunnel, the method that present unit in charge of construction takes is freezing ice cube outside tunnel, the ice cube made is transported in tunnel, or increase multiple stage gas blower relay carries fresh air to mediate in hole the measures such as sultry air from hole, reach the object that cooling is ventilated, guarantee that the healthy of workmen and construction carry out smoothly with this. But such mode, inefficiency, brings inconvenience to construction side.
Practical novel content
For current above-mentioned technology Problems existing, the utility model provides simple, the easy to operate constructing tunnel ventilation refrigeration system of a kind of structure.
The technical solution adopted in the utility model is, constructing tunnel ventilation refrigeration system, this refrigeration system is arranged in construction tunnel, described refrigeration system comprises condenser system and the recycle system, described condenser system comprises the water cooler for storage of water, the water cooling tube being connected with water cooler, the first water pump being arranged on water cooling tube, this condenser system also comprises condenser, throttling valve, the refrigeration plant of vaporizer and compressor composition, this condenser system is connected with the recycle system, water in this refrigeration system flows to the recycle system through refrigeration plant, water refluxes into condenser system through the recycle system, the described recycle system comprises circulation line, this circulation line it is provided with in described vent line.
By arranging refrigeration system in vent line, vent line in construction tunnel is carried out refrigeration process, this refrigeration system is arranged on described vent line, carry, easy to operate, structure simple, carrying out smoothly of the healthy of workmen and construction can be guaranteed preferably.
Further, the described recycle system also comprises water tank and the 2nd water pump, and described water tank and the 2nd water pump are arranged on described circulation line.
Water tank is used for supplementing heat-eliminating medium-water, by the 2nd water pump, water is transported to condenser system.
Further, the described recycle system also comprises the 2nd water pump, and the 2nd water pump is connected by circulation line with river or reservoir.
When water source resources such as Pang You rivers, tunnel, just can utilize water source resource, it is necessary to time with supplementary heat-eliminating medium-water.
Further, the part that described circulation line is arranged in vent line be that spatial grid structure is distributed in vent line and prolongs vent line and extend layout.
After circulation line in vent line is set to spatial grid structure, forming refrigeration area in described vent line, this region is more long, and refrigeration is more good, and refrigeration area is arranged with length and the actual needs of vent line.
Further, it is provided with air cooler in described vent line.
Further, the circulation line being arranged at vent line described in is arranged in air cooler.
Here arranging air cooler is lowered the temperature further by the air-flow in vent line, the minimum temperature that setting air cooler degree of being lowered the temperature here can freeze lower than refrigeration system certainly.
The beneficial effects of the utility model are:
By arranging refrigeration system in vent line, vent line in construction tunnel is carried out refrigeration process, this refrigeration system is arranged on described vent line, carry, easy to operate, structure simple, carrying out smoothly of the healthy of workmen and construction can be guaranteed preferably.
Accompanying drawing explanation
Fig. 1 is the structural representation of constructing tunnel ventilation refrigeration system.
