Description
Technical field
The utility model relates to field of refrigeration, particularly relates to a kind of refrigeration system consuming nitrogen workshop.
Background technology
Usually the nitrogen that we use not is directly exist with the form of gas starting most to be stored in nitrogen pot, but stores in the mode higher than atmospheric pressure in the mode of liquid.When our workshop needs to use nitrogen, first liquid nitrogen is discharged by pressure from nitrogen pot, has liquid state to be that gaseous state enters workshop for normal by conveyance conduit again through gasifier.
The physical characteristic of liquid nitrogen is: liquid nitrogen.Be inertia, colourless, odorless, non-corrosiveness, non-combustible, temperature is extremely low.Nitrogen constitutes the major part (volume ratio 78.03%, weight ratio 75.5%) of air.Nitrogen is inactive, does not support burning.Contact of absorbing heat in a large number during vaporization causes frostbite.At ambient pressure, liquid nitrogen temperature is-196 DEG C; The liquid nitrogen of 1 cubic metre can be expanded to the pure gaseous nitrogen of 696 cubic metres 21 DEG C.Normal atmosphere is depressed, and during boiling point-195.8 DEG C, the heat of vaporization of liquid nitrogen is 2.7928 kj/mol.Liquid nitrogen density 810 kilograms every cubic metre, liquid nitrogen molecular weight 28, so one cube of liquid nitrogen gasification absorbs heat=(1*810/28) * 2.7928=80.79 kilojoule.
But major part needs the workshop consuming nitrogen now, nitrogen be directly from liquid nitrogen container by Cemented filling to workshop, wherein, liquid nitrogen vaporization becomes gas nitrogen, absorbs amount of heat, this point, do not obtain utilization carefully, and workshop is in the summer of sweltering heat, also needs to open air conditioner refrigerating, more waste resource and the energy.
Utility model content
In view of this, be necessary to provide a kind of economize energy and resource, and the refrigeration system of the consumption nitrogen workshop that can recycle.
The utility model realizes like this, a kind of refrigeration system consuming nitrogen workshop, comprise liquid nitrogen container and gas pipeline, described liquid nitrogen container is connected in workshop by gas pipeline, also comprise gasifier, water receiving tank, booster water pump, fan coil and spray thrower, described gasifier is located on gas pipeline, one end of described gasifier is communicated with liquid nitrogen container, the other end is connected in workshop, described water receiving tank is located at immediately below gasifier, water receiving tank connects booster water pump by pipeline, booster water pump connects spray thrower by pipeline through fan coil, described fan coil is located at top or the inside of workshop, described spray thrower is located at directly over gasifier.
A kind of advantage consuming the refrigeration system of nitrogen workshop that the utility model provides is: the utility model structure is simple, by arranging gasifier, liquid nitrogen in liquid nitrogen container is through gasifier, be transformed into nitrogen, endothermic process can be produced, gasifier surface is made to produce ice crystal, by arranging water receiving tank, booster water pump, fan coil and spray thrower, water receiving tank connects booster water pump by pipeline, booster water pump connects spray thrower by pipeline through fan coil, described fan coil is located at top or the inside of workshop, described spray thrower is located at directly over gasifier, sprayed water to gasifier by spray thrower, the ice crystal that water adheres on gasifier can freeze rapidly, like this, a large amount of cooled water is collected by water receiving tank, through booster water pump, water recycle is delivered in spray thrower, because the water of cooling is through fan coil, water releasing cool air here cooled in fan coil, sent in workshop by ventilation shaft and freeze, water after releasing cool air is risen again gradually, and got back in spray thrower by pipeline and again spray to gasifier and be recycled.
Utilize our this mode first can reduce ice crystal quantity on gasifier, the efficiency that liquid nitrogen transforms can be improved; And this refrigeration modes is got involved without the need to extra refrigerant, freeze according to the energy be wasted in the past completely, without extra charge, green, environmental protection, without other all pollutions, and with low cost, mass energy and resource can be saved, and can recycle.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation consuming the refrigeration system of nitrogen workshop of the utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is a kind of structural representation consuming the refrigeration system of nitrogen workshop of the utility model.
Described a kind of refrigeration system consuming nitrogen workshop, comprise liquid nitrogen container 10 and gas pipeline 20, described liquid nitrogen container 10 is connected in workshop 30 by gas pipeline 20, also comprise gasifier 40, water receiving tank 50, booster water pump 60, fan coil 70 and spray thrower 80, described gasifier 40 is located on gas pipeline 20, one end of described gasifier 40 is communicated with liquid nitrogen container 10, the other end is connected in workshop 30, described water receiving tank 50 is located at immediately below gasifier 40, water receiving tank 50 connects booster water pump 60 by pipeline, booster water pump 60 connects spray thrower 80 by pipeline through fan coil 70, described fan coil 70 is located at top or the inside of workshop 30, described spray thrower 80 is located at directly over gasifier 40.
