Description
Technical field
This utility model relates to a kind of nitrogen cold system.
Background technology
At chemical field, application nitrogen is very frequent, but the storing mode of nitrogen is generally liquid nitrogen, and when using, liquid nitrogen need to be converted into nitrogen and use, and liquid nitrogen stores to nitrogen storage tank after nitrogen carburator is vaporized, being supplied workshop by nitrogen storage tank, and workshop nitrogen is room temperature, nitrogen has a large amount of loss of refrigeration capacity when carburator enters nitrogen storage tank, have lost the substantial amounts of energy, cause the height of cost.
Utility model content
The purpose of this utility model is to provide a kind of nitrogen cold system, and simple in construction is easy to operate, takes full advantage of liquid nitrogen and is converted into the cold of nitrogen, energy-saving and cost-reducing, reduces cost.
A kind of nitrogen cold system described in the utility model, including liquid nitrogen storage tank, liquid nitrogen storage tank is by pipeline and chilled brine storage tank, chilled brine storage tank passes through pipeline and circulating water pool, circulating water pool is by pipeline and nitrogen carburator, nitrogen carburator is connected with nitrogen storage tank by pipeline, and nitrogen storage tank is connected with workshop by pipeline.
Chilled brine storage tank top arranges brine inlet.
Circulating water pool top arranges circulating water intake.
The tank skin of chilled brine storage tank arranges the first coil pipe.
The second coil pipe is set in circulating water pool.
Circulating water pool bottom arranges out water pump.
Chilled brine storage tank bottom arranges out brine pump.
Arranging the first coil pipe on the tank skin of chilled brine storage tank, liquid nitrogen is lowered the temperature to chilled brine by coil heat exchange, reduces ice maker load.
Arranging the second coil pipe in circulating water pool, liquid nitrogen passes through coil pipe to circulating water cooling.
Liquid nitrogen storage temperature is-196 degree, makes full use of this part cold, reaches the purpose saved energy and reduce the cost.
Liquid nitrogen, by the chilled brine reservoir of liquid nitrogen storage tank, is lowered the temperature to chilled brine by brine reservoir inner coil pipe.
Liquid nitrogen after intensification is through circulating water pool, by circulating water pool inner coil pipe to circulating water cooling.
The nitrogen of gaseous state, after carburator is fully vaporized, enters nitrogen storage tank.
Compared with prior art, this utility model has the advantages that
This utility model nitrogen cold system, simple in construction, easy to operate, take full advantage of liquid nitrogen and be converted into the cold of nitrogen, energy-saving and cost-reducing, reduce cost.
