The recent explosions have caused chemical companies to step up safety inspections in the storage, transportation and production of hazardous chemicals. According to industry insiders, from the technical point of view, China's explosion-proof materials and devices have become mature, and many explosion accidents may be avoided. For example, barrier explosion-proof technology is a viable option.
Wang Huanqing, general manager of Taian Shi'an Barrier Explosion-Proof Materials Co., Ltd., said in an interview with China Chemical Industry News that many explosion accidents failed to control the fire in the initial stage of the fire, so that the leak was only caused by a small area or the fire was finally triggered. Explosive explosion.
According to Wang Huanqing, the barrier-proof technology can prevent explosions caused by accidents such as static electricity, open flames, welding, shooting, collision and wrong operation, and avoid large accidents. The technology uses an explosion-proof material made of aluminum alloy material, and uses the flame blocking effect, heat conduction effect and free radical wall adsorption effect to fill the honeycomb explosion-proof material in the fueling (gas) station, the oil tanker truck and the loading flammable In the container device for explosion and liquid hazardous chemicals, the problem of liquid overflow and flame propagation is fundamentally solved, and the accident is contained in the bud.
In addition, the technology can also inhibit the evaporation of oil and gas in the container, reduce the flame height, prevent the surge, reduce the liquid sloshing in the container, and achieve the effect of eliminating the static electricity of the hazardous chemicals container and reducing the oxidation rate of the oil. Wang Huanqing said that on the basis of the existing technology, the future transportation, storage and packaging of hazardous chemicals can be further upgraded.
The TTJ fire-proof and explosion-proof refueling device produced by Shandong Titanium Titanium Industry Co., Ltd. is also filled with this aluminum alloy barrier explosion-proof material, which enhances the safety of gas stations, especially for residential communities, large parking lots, and highways. Service stations and gas stations near the port terminal. The device also has the function of suppressing oil and gas volatilization and reduces oil consumption.
The barrier explosion-proof technology is mature and the cost is not high. Why is it not widely used in the chemical industry? The reporter learned from Titanium Titanium Industry Co., Ltd. that the barrier-proof technology is popular in foreign countries and the use time is longer. From the domestic point of view, as early as 2005, the government and scientific research institutions have conducted an inspection on the barrier-proof technology. The State Administration of Work Safety has also issued documents on the promotion and application of barrier-proof technology, and formulated safety technical standards. The implementation was promoted and encouraged. However, over the years, in addition to the introduction of some local gas stations under Sinopec and PetroChina, there are not many enterprises that actively use barrier-proof materials.
The reason is that on the one hand, the popularity of such technologies is not enough. Most enterprises have insufficient knowledge of products and cannot apply them to production in time. On the other hand, security measures require costs, and there is no mandatory requirement in the government. In the case of enterprises, companies are often reluctant to invest in places where they do not see the benefits in a short period of time, which has led to the failure of the explosion-proof technology to play its due role.
