Utility model content
In order to solve the problem, the utility model devises a kind of liquid nitrogen heating apparatus, and energy resource consumption is few, while being heated by liquid nitrogen and obtaining nitrogen, also for heat exchanger provides cooling water, solve refrigeration problem, not only provide cost savings, decrease the additional configuration of equipment.
The technical solution of the utility model is:
A kind of liquid nitrogen heating apparatus, comprise cistern, be provided with liquid nitrogen heating tube in described cistern, one end of described liquid nitrogen heating tube is liquid nitrogen import, and is connected with liquid nitrogen storage tank, the other end is outlet, described liquid nitrogen heating tube is that inflection shape or helical form are arranged in described cistern, thus adds heating surface area, improves the efficiency of heating surface, liquid nitrogen is heated more evenly fast, and liquid nitrogen is heated to gasify and is made the coolant-temperature gage in cistern reduce simultaneously; The two ends of described cistern are respectively equipped with water inlet and delivery port, and are connected with the heat exchanger tube of heat exchanger by pipeline, and are provided with water circulating pump, form water circulation, thus the water at low temperature in cistern is transported in heat exchanger, as cooling water, refrigeration is provided, is then returning in cistern.
Further, described heat exchanger is air-cooled heat exchanger or water-cooled heat exchanger, such as, can be air-cooled air conditioner or Water-cooling type air conditioner.The water of cistern is as the heat-exchange medium of Water-cooling type air conditioner, water is at the heat exchange Bottomhole pressure of heat exchanger, carry out heat exchange by the cold-producing medium in tube wall and heat exchanger package, complete heat transmission, the water in cistern is heated, thus complete liquid nitrogen and heat, effectively make use of the waste heat that heat exchanger refrigeration produces, simultaneously for heat exchanger refrigeration provides cooling water, kill two birds with one stone, improve utilization rate of equipment and installations, reduce cost.
Further, pressure sensor and temperature sensor is provided with in described liquid nitrogen heating tube, and be provided with magnetic valve, described pressure sensor is all connected with controller with the output of temperature sensor, described controller is connected with described solenoid control, by controller according to the keying of Numerical Control magnetic valve of pressure sensor and temperature sensor and the uninterrupted of liquid nitrogen, makes liquid nitrogen heat fully, when hypertonia in liquid nitrogen heating tube, Controlling solenoid valve reduces flow; During hypertonia, Controlling solenoid valve increases flow; Controlling solenoid valve augmented flow when temperature is too high, when temperature is too low, Controlling solenoid valve reduces flow.
Further, the liquid nitrogen import of the water inlet of described cistern and delivery port and described liquid nitrogen heating tube and export setting direction contrary, i.e. the side of liquid nitrogen import is delivery port, and the side of outlet is water inlet, thus makes to heat more evenly, improves the thermal efficiency.
In addition, described cistern can also be provided with solar energy vacuum tube, one end of described solar energy vacuum tube is positioned at described cistern, described solar energy vacuum tube is full glass double-vacuum heat pipe, by solar energy vacuum tube, the current in cyclic water tank are heated, complete liquid nitrogen by the heat that can provide very much to heat, reduce cost.
Liquid nitrogen in liquid nitrogen heating tube absorbs the heat of retaining pool inner water and gasifies, after heat-shift, the temperature of retaining pool inner water reduces, by water circulating pump the water in cistern is transported to heat exchange in the heat exchanger in Office Area and factory building thus environment is lowered the temperature, water after heat exchange flows back in cistern again, achieve and the heat in environment and liquid nitrogen are exchanged, the cold produced when effectively make use of liquid nitrogen gasification, reduces energy resource consumption, provides cost savings.
The utility model has the advantage of: energy resource consumption is few, while liquid nitrogen is heated obtaining nitrogen, also for heat exchanger provides cooling water, solve refrigeration problem, not only provide cost savings, decrease the additional configuration of equipment.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
