Description

Technical Field

[0001] The invention belongs to the field of nuclear accident disposal, and specifically relates to a G3 air copolymer film fire control agent and a preparation method thereof, and a fire control method based on high-temperature, high-pressure and high-radiation smoke column emergency. Background Art

[0002] As is known, the high-temperature, high-pressure, and highly toxic smoke column formed by explosion or combustion-like nuclear accidents expands and spreads quickly, harms a wide range, and emergency disposal is complex and difficult. Accident emergency response is an important means to effectively control hazards, protect the environment and human life safety.

[0003] Due to the complexity of environmental conditions, the diversity of disposal objects, the particularity of nuclear hazards and the timeliness of emergencies, nuclear safety emergency means and methods have become key technologies in the field of safety emergencies.

[0004] From the theoretical research and analysis of nuclear accident safety emergency technology, it can be seen that the safety emergency technology is different due to different emergency conditions and emergency requirements. For example, in the face of splashed or settled radioactive pollutants, the continuous copolymer film control method based on the continuous copolymer film control agent is often used; to avoid nuclear pollution indoors or in equipment, the self-breaking copolymer film control method based on the self-breaking copolymer film control agent is often used; indoor air is often used for air exchange filtration or adsorption sedimentation; outdoor near-ground suspended toxic and harmful dust is often used for water sedimentation or adsorption sedimentation. The above emergency disposal of nuclear hazards is mostly a disposal method under normal temperature and normal conditions in the later stage of the accident, which is a kind of emergency disposal that is to make up for the loss.

[0005] In the early stages of an accident, the objects of emergency disposal are mostly high-temperature, high-pressure, and highly toxic (G3) smoke columns generated by explosions or combustion-type nuclear accidents. Due to the persistence of explosions or combustion, rapid expansion, and diffusion with the airflow, the hazards and destructiveness of G3 smoke columns double over time. Therefore, the principle of artificial intervention in the process of explosions or combustion-type nuclear accidents, that is, the initial emergency disposal, is that the earlier the intervention time, the better. At the same time, early intervention is more conducive to the elimination of G3 smoke columns. The most commonly used intervention method for explosions or combustion-type nuclear accidents is the water spraying method. Therefore, the water method is not an effective means of intervention emergency or accident process intervention for the smoke column of explosions or combustion-type nuclear accidents. It is urgent to develop new emergency intervention technologies to solve the problem of the hazards of G3 smoke columns in explosions or combustion-type nuclear accidents.

[0006] In summary, in view of the shortcomings of the water-based emergency intervention technology for G3 smoke column hazards in explosion or combustion-type nuclear accidents, a fire control functional material and method that can replace water for early emergency intervention is proposed to meet the urgent needs of emergency response to explosion or combustion-type nuclear accidents.

[0024] Based on the same technical concept, the present invention further provides a method for preparing the G3 air copolymer film control agent, the preparation method comprising the following steps:

[0031] (1) Determine the general shape (diameter, possible temperature and pressure inside the smoke column) and real-time atmospheric environment (especially the atmospheric disturbance index) of the high-temperature, high-pressure and high-toxicity smoke column according to the emergency response requirements of nuclear accidents;

[0032] (2) The dispersed release machinery is selected according to the environmental characteristics and mission requirements.

[0035] The beneficial effects of the present invention are:

[0036] 1. The G3 air copolymer film fire control agent of the present invention has scientific raw material matching and complementary functions, specifically: the synergistic effect of organic resin, high temperature resistant filler and flame retardant greatly improves the high temperature resistance of the fire control material, and it not only has the film-forming property of organic resin but also has the excellent high temperature resistance of high temperature resistant filler and flame retardant, improves the flame retardancy, dripping and pulverization under high temperature and high pressure, and a large amount of -Si-O- cross-linked structure provides a skeleton effect of high-density silicate shell under high temperature environment, and the inorganic salt film layer plays an oxygen-isolating and flame-retardant role, that is, it forms high temperature heat corrosion resistance, and the high temperature structure has excellent mechanical properties; the catalyst used in the present invention participates in the curing and film-forming process, and has the functions of high temperature film-forming and room temperature film-forming, which expands the application scope of the fire control material and optimizes the heating and baking process of the general single-component high temperature resistant resin during the molding, film-forming and drying processes.

[0037] 2. The fire control method of the present invention sprays the G3 smoke column air copolymer film fire control agent used for emergency fire control of high-temperature, high-pressure and high-toxic smoke columns in explosion or combustion nuclear accidents onto the top of the G3 smoke column, blocking the way for the G3 smoke column to rise and quickly reducing the height of the smoke column until there is no height, which significantly reduces the pollution concentration in the high altitude; it can also roll inward and absorb heat in the middle axis of the smoke column, effectively controlling the external expansion diameter of the smoke column, minimizing the cross-sectional area of ​​the fire control, minimizing the scope of harm, and minimizing the amount of fire control agent used; it can be realized Extinguish fire at the fire source and interrupt the continuous release of toxic and harmful substances; effectively adsorb and settle toxic and harmful substances in the G3 smoke column, forcing them to form a non-flowing copolymer gel state with the fire control agent, which does not flow or penetrate after settling to the ground; and the copolymer gel formed with the toxic and harmful substances in the smoke column can continue to copolymerize with the sediment on the ground, controlling the re-suspension and underground penetration of toxic and harmful substances on the ground; the nuclear contaminated copolymer film formed on the ground is a solid matter that can be peeled off and transferred, which is easy to collect, concentrate and dispose of, and has no hazards of radioactive wastewater storage and discharge.

9. A fire control method based on high temperature, high pressure and high radiation smoke column emergency, characterized in that: Using the G3 air copolymer film control agent according to any one of claims 1 to 6, the control method comprises the following steps: (1) Determine the shape and real-time atmospheric environment of the high-temperature, high-pressure, and highly toxic smoke column according to the emergency response requirements of nuclear accidents; (2) The dispersed release machinery is selected according to the environmental characteristics and mission requirements. The mission requirements are: release at the top of the G3 smoke column to cover the head of the smoke column; high-speed jet flow in the middle axis of the smoke column to facilitate the inward roll of the smoke column; the environmental temperature is in the range of -20 to 500°C, and the maximum wind speed is level 4; (3) According to the task requirements of step (2), the G3 smoke column head section is 2.0-3.0 kg / m 2 The amount of the G3 air copolymer film fire control agent multiplied by the column height is continuously sprayed from top to bottom onto the G3 column head, fully covering the G3 smoke column head, forming a negative pressure zone in the middle axis of the smoke column, causing inward roll, forcing the smoke column to gather inward to the middle axis zone, and limiting the outward expansion of the smoke column; (4) At the same time, the G3 air copolymer film fire control agent and the toxic and harmful dust particles in the smoke column collide, wetting, adsorb, copolymerize, and increase weight, so that the toxic and harmful substances in the smoke column settle to the ground or the fire source in the form of copolymer gel, and through the form of heat absorption and heat conversion, the temperature in the smoke column is reduced, the flames are covered and the fire is extinguished. Due to the copolymerization, heat absorption and evaporation process between the G3 air copolymer film fire control agent and the toxic and harmful particles in the smoke column, the G3 air copolymer film fire control agent settles to the ground and forms a non-flowing gel.
