Description
Technical field
This utility model relates to liquid nitrogen plant technical field, is specifically related to pressure liquid nitrogen feeding mechanism.
Background technology
Liquid nitrogen: the nitrogen of liquid.Being inert, 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.Absorbing heat in a large number during vaporization, contact causes cold injury.
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 of 21 ° of C.Liquid nitrogen is colourless, tasteless, under high pressure the liquids and gases of low temperature.Liquid nitrogen (is often written as LN2), is the liquid form that formed at low temperatures of nitrogen.The boiling point of nitrogen is-196 ° of C, at normal atmospheric pressure, if temperature will form liquid nitrogen below this;If pressurization, liquid nitrogen can be obtained at higher temperatures.
In industry, liquid nitrogen is to be obtained by air distillation.First by after air cleaning, liquefying in the environment of pressurization, cooling, the boiling point difference by component each in air is separated.Helium releases (and not being liquefied) at first, is the nitrogen of 78.09% in duty gas with that, then be account for 20.95% oxygen, be finally the argon of 0.93% in duty gas.
Human body can be damaged by liquid nitrogen generation leakage, when liquid nitrogen leaks, spray water can be used quickly to evaporate liquid nitrogen, due to existing pressure liquid nitrogen feeding mechanism only storage and supplying functional, when there is leakage in liquid nitrogen, it is impossible to enough being evaporated liquid nitrogen in time processes, it would be highly desirable to improve.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, a kind of simple in construction is provided, pressure liquid nitrogen feeding mechanism reasonable in design, easy to use, the initial stage of leakage can be occurred just can in time leakage liquid nitrogen to be processed at liquid nitrogen, effectively reducing liquid nitrogen and leak the harm brought, practicality is higher.
For achieving the above object, the technical solution adopted in the utility model is: it comprises tank body, inner bag, neck tube, multilayer thermal insulation, outlet, locking closure, handle；The inside of tank body is provided with inner bag, is provided with multilayer thermal insulation between inner bag and tank body, and the top of inner bag is connected with outlet by neck tube, and outlet is provided with locking closure, and tank body is provided with handle；It also comprises water storage box, water tubular union, hydraulic giant, nitrogen concentration tester, controller；Water storage box is arranged on the lateral wall of tank body, the side of water storage box is connected by water tubular union hydraulic giant, hydraulic giant is connected with the water pipe in water tubular union, water pipe in water tubular union is connected with water storage box, the sidewall of water storage box is provided with controller, the side of outlet is provided with nitrogen concentration tester, and nitrogen concentration tester is connected with controller.
The inside of described water tubular union is hollow-core construction.
One end of described water tubular union is provided with screw thread and spins end, spins with the sidewall of water storage box, when not in use, is rotated down by hydraulic giant.
Operation principle of the present utility model: after entirety places, being rotated by hydraulic giant makes muzzle upward, when liquid nitrogen has leakage, after leakage tested by nitrogen concentration tester, start controller, triggering hydraulic giant and carry out water spray process, the water smoke of ejection effectively reduces liquid nitrogen concentration, processes the liquid nitrogen of leakage in time.
