Abstract
The conventional reactor in a nuclear power station is cooled by water, and the temperature is not reduced so as to cause explosion of the nuclear power station and nuclear radiation harm to humans. In the invention, the reactor is cooled by nitrogen instead of water. The main core technology of a reactor cooling device in the nuclear power station is that: the device consists of a liquid nitrogen storage tank, a liquid nitrogen pump, an evaporator, an electric valve, a pipeline, a check valve, a relief valve, a pressure gage, a liquid level gage, a vacuum meter, an automatic control board, a circuit and a nuclear reactor cooling cover. In the core technology, liquid nitrogen at 196 DEG C below zero in a liquid nitrogen storage device is radiated to the nuclear reactor to be gasified, an ideal cooling effect is achieved, and the needed temperature can be adjusted. When the gasified nitrogen is cooled by a nuclear reactor cover for recycle, the nitrogen is injected into the storage tank device and becomes liquid to be unlimitedly used; therefore, the cost is reduced; because the nitrogen is inert gas, the nitrogen is non-conductive and environment-friendly, has functions of preventing explosion and extinguishing fire; and the nitrogen does not destroy the atmospheric layer and the ozone layer, is a byproduct in an oxygen manufacture factory, is low in cost, has the advantages of energy saving, emission reduction and ultra-low in temperature, serves as a cooling agent to solve worldwide problems, and contributes to benefiting human beings.
Description
Technical field:
The invention belongs to equipment manufacture industry, the nuclear power plant reactor heat sink is to be cooling agent with liquid nitrogen, replaces present countries in the world water to come to the nuclear power plant reactor cooling, and water for cooling is not optimal.In order to solve the source problem of water, most of country all build nuclear power station in seashore, bring numerous difficulties to construction, cost strengthens, the blast on fire of the bad USSR (Union of Soviet Socialist Republics) nuclear power station of effect, Japan's earthquake initiated core power station blast today, water generates hydrogen causes gas burst, does not all cause because of water for cooling reaches effect.Initiated core is revealed human body is suffered nuclear radiation.
Water is temperature above freezing, and liquid nitrogen is subzero 196 degrees centigrade.It is the most desirable cooling agent of nuclear power plant reactor at present, allows the Nuclear Power Station reactor not reach high temperature blast on fire forever.
Background technology:
This nuclear power plant reactor heat sink, core technology are that liquid nitrogen plan is that many one-tenth chuck insulation combine, the outside aluminium foil multi-layer packaging of using, and inner bag is handled with the special steel plate sanding and polishing.Make the tank arrangement size by nuclear power plant reactor cooling protection district size.
Summary of the invention:
The nuclear power plant reactor heat sink is made up of liquid nitrogen storage tank, electronic self-actuated controller, liquid nitrogen pump electrically operated valve, nitrogen cooling cover four major parts, and liquid nitrogen storage tank can be horizontal, vertical.
The nuclear power plant reactor heat sink is made up of storage tank, liquid nitrogen pump, electrically operated valve, easing valve, tensimeter, vacuum meter, fluid level gauge, evaporator, pipeline, nuclear reactor protection cover, return-air duct, reverse checkvalve, autokeyer dish, circuit.
Open liquid flowing valve, open tapping valve and adorn liquid, prove when discharge opeing and fill that two valves cut out.The unlatching outlet valve is converted nuclear reactor and is normally lowered the temperature, when but the undesired urgent need fast cooling of nuclear reactor temperature is opened liquid nitrogen pump, fast cooling just automatically, after reaching ideal temperature, liquid nitrogen reformed gas, can return again and change into liquid in the liquid nitrogen storage tank, increase pressure of storage tank, make it the storage tank liquid nitrogen and discharge automatically, nuclear reactor is normally lowered the temperature.
The liquid nitrogen storage temperature is subzero 196 degrees centigrade, is that water is inaccessible forever, and water to produce nitrogen be unfavorable factor to nuclear power station.Japan's violent earthquake, nuclear power station blast are that water vapor causes, so the nuclear power plant reactor cooling is a world-famous puzzle.
Blast can be lowered the temperature, be stoped to nitrogen, can put out a fire again, stop burning, be oxyen manutactory's secondary product, inexpensive, be inert gas non-conductive, again clean with after go back to nature, inexhaustible use do not finish, free from environmental pollution.
