Description
Technical Field
The invention relates to the technical field of pressure containers, in particular to a high-pressure remote monitoring and filling system.
Background
The pressure container is a comprehensive product relating to multiple industries and multiple disciplines, and the construction technology of the pressure container relates to multiple industries such as metallurgy, machining, corrosion and corrosion prevention, nondestructive testing, safety protection and the like. The pressure vessel is widely applied to chemical, petroleum, mechanical, power, metallurgy, nuclear, aviation, aerospace, ocean and other departments, and is essential core equipment in the production process.
According to the current state analysis and development prospect research report of the 2018-plus 2025 global and Chinese pressure vessel industry published by the Chinese industry research network, along with the continuous progress of the technologies such as metallurgy, mechanical processing, welding and nondestructive testing, particularly the rapid development of the information technology represented by the computer technology, the development of the related industries is driven, and the pressure vessel technology field also makes corresponding progress on the basis of the deep research of a large amount of manpower and material resources input in various countries in the world.
In the development process of military products, pressure containers are damaged, and mainly the pressure containers are broken, and pipelines are damaged and thrown out to hurt people. The hazard is mainly a physical explosion phenomenon, and is that high-pressure gas in a pressure container rapidly expands and releases internal energy at a high speed.
The existing pressure vessel mainly has the following three difficulties:
(1) shock wave and its destructive action: shock wave overpressure can cause casualties and building damage. When the overpressure of the shock wave is more than 0.10MPa, most people die under the direct impact of the shock wave: an overpressure of 0.05-0.10MPa can seriously damage the internal organs of a human or cause death; overpressure of 0.03-0.05MPa can damage human auditory organs or produce fractures; the human body can be slightly injured even if the overpressure is 0.02-0.03 MPa.
(2) Destructive action of blasting fragments: when the pressure container is broken and exploded, the high-speed ejected air flow can push the shell body out reversely, and some shell bodies are broken into blocks or pieces to scatter around. These fragments, which have a higher velocity or a greater mass, have greater kinetic energy during the flight and can also cause greater damage. The degree of injury to a person by the debris depends on its kinetic energy, which is proportional to its mass and the square of its velocity. The fragments often have an initial velocity of 80-120m/s when they exit the housing, and often have a velocity of 20-30m/s even when flying further away from the centre of the blast. At this speed, the kinetic energy of the fragments with a mass of 1kg can reach 200- & lt 450 & gtJ, which can cause serious injury or death. Debris can also damage nearby equipment and piping, causing a continuous explosion or fire, causing even greater damage.
(3) Medium damage: the medium comprises two non-combustible inert gases of nitrogen and argon, the main harm is that the nitrogen and the argon have asphyxiability, and when the nitrogen and the argon are leaked, the content of the nitrogen in the air is too high, so that the partial pressure of oxygen in the inhaled air is reduced, and the oxygen deficiency asphyxiation of people is easily caused.
On 6/5/2016, an employee of Shenzhen, Longhua New zone Guanlan pavilion Daxing gas Co., Ltd was exploded in a nitrogen bottle during filling nitrogen, and the employee died. In 11 months in 2011, the nitrogen suffocation accident happens in the shogao station in metropolis, so that 2 people die and 3 people are injured.
The high-pressure gas station (55MPa) is used as a level II danger point, and the safety risk of explosion of a pressure container and a pipeline thereof exists in the operation process of personnel, so that the safety research of a remote monitoring and filling system of the high-pressure gas station is needed, the requirements of pressure point staff reduction and mechanical and automatic staff reduction are met, the intrinsic safety is realized, and the safety of the personnel is ensured.
At present, the safe use research of pressure vessels at home and abroad mainly adopts the following research measures:
(1) in design, a reasonable structure, such as a full penetration welding structure, can be freely expanded, and the like, so that stress concentration and geometric mutation are avoided; aiming at the use condition of the equipment, a material with better plasticity and toughness is selected; the intensity calculation and the safety valve displacement calculation meet the standard.
(2) When manufacturing, repairing, installing and transforming, welding management is strengthened, welding quality is improved, and heat treatment and flaw detection are carried out according to standard requirements; the management of materials is enhanced, and defective materials or wrong steel materials and welding materials are avoided.
(3) In the use process of the pressure container, the management is enhanced, and misoperation, over-temperature, over-pressure and overload operation, failure detection, failure repair, failure of a safety device and the like are avoided.
(4) And the inspection work is strengthened, the defects are found in time, and effective measures are taken.
Meanwhile, a gas drive nitrogen pressurization system in the existing high-pressure gas station adopts a manual mode to control the on-off of each valve, various functions are realized according to the on-off of each valve, and a pressure regulating valve also adopts a manual mode, as shown in fig. 2, so that the intelligent degree is low.
Along with the promotion of the automation level of products and the promotion of personal safety protection, the automatic control can be realized through the intelligent transformation and upgrade of the existing pressurization system, and the intelligent transformation is carried out on the gas drive nitrogen pressurization system in the existing high-pressure gas station, as shown in figure 1.
