Description
Technical field
The utility model relates to liquid nitrogen gasification cold recovery system.
Background technology
Nitrogen generally participates in and protects chemical reaction in chemical process as protective gas. Nitrogen is that liquid nitrogen first gasifies through being exposed to airborne vaporizer, then is delivered to each reactor by conveyance conduit after reduced pressure treatment. Mainly the heat of suction-type carbureter outside air because liquid nitrogen gasifies in vaporizer, cause can forming bloom in evaporator surface under the effect of the cold that airborne water produces in the time of liquid nitrogen gasification, very easily cause liquid nitrogen in vaporizer, to gasify not exclusively, after flowing to conveyance conduit, the incomplete nitrogen of gasification can continue endothermic gasification, thereby conveyance conduit is moved at extremely low temperature, not only greatly shorten the service life of conveyance conduit, increase maintenance cost, and be that the safety of producing has been buried hidden danger smoothly.
Utility model content
The purpose of this utility model is to provide a kind of liquid nitrogen gasification cold recovery system of the cold producing can recycle liquid nitrogen gasification time.
For achieving the above object, the utility model has adopted following technical scheme: described liquid nitrogen gasification cold recovery system, comprise power refrigeration equipment, reactor, liquid nitrogen tank, cooling water storage tank, the liquid nitrogen cold recovery case of vaporizer and the full cooling water of storage, on the wall box of liquid nitrogen cold recovery case, be respectively arranged with liquid nitrogen import, nitrogen outlet, cooling water inlet and coolant outlet, described vaporizer is arranged in liquid nitrogen cold recovery case, the inlet of vaporizer is connected with the liquid nitrogen import of liquid nitrogen cold recovery case, the gas outlet of vaporizer is connected with the nitrogen outlet of liquid nitrogen cold recovery case, described liquid nitrogen tank is connected with the liquid nitrogen import of liquid nitrogen cold recovery case by input duct, the nitrogen outlet of liquid nitrogen cold recovery case is connected with reactor by outlet pipe, described cooling water storage tank is connected with the cooling water inlet of liquid nitrogen cold recovery case by inlet channel, the coolant outlet of liquid nitrogen cold recovery case is connected with power refrigeration equipment by outlet conduit.
Further, aforesaid liquid nitrogen gasification cold recovery system, wherein: on inlet channel, be provided with delivery pump.
By the enforcement of technique scheme, the beneficial effects of the utility model are: the cold producing during by liquid nitrogen gasification is used for cooling and flows into the cooling water of power refrigeration equipment, on the one hand, the cold producing when fully having recycled liquid nitrogen gasification, evaporator surface will can not be tied bloom, liquid nitrogen can be gasified completely after vaporizer, the safety that has not only ensured production is carried out smoothly, and make can at extremely low temperature, not move for the pipeline of supplying nitrogen, greatly extend the service life of pipeline, reduced the production maintenance cost of enterprise; On the other hand, the cooling water after cooling flows into after power refrigeration equipment, can reduce the operating cost of power refrigeration equipment, thereby save electric energy.
