First, dust explosion accident cases

In recent years, dust explosion accidents occur frequently, which involve a wide range, strong destructive, significant harm, has become a major safety hazard in industrial production. Five people were killed in a serious dust explosion at Qingdao Qianbaiwei Food Ingredients Co., Ltd. in Jimo district of Qingdao, Shandong province. Preliminary analysis showed that the cause of the accident was the mechanical spark generated by the friction of metal debris during the installation and commissioning of the equipment, which triggered the initial explosion of starch dust, followed by the secondary explosion caused by the shock wave. This painful lesson once again reminds us that the prevention and control of dust explosion is urgent.

Second, the principle and harm of dust explosion

Dust explosion refers to the violent combustion phenomenon that occurs when combustible dust meets a heat source (such as an open flame or high temperature) within the explosion limit. Because dust explosions often have chain-reaction characteristics, one explosion may trigger multiple explosions, causing serious casualties and property losses. The destructiveness of dust explosion is not only reflected in the high temperature and high pressure at the moment of explosion, but also in the secondary disasters that it may cause such as fire and building collapse.

Three, Point Stone high-tech: dust explosion test solutions leader作As a leading enterprise in the field of dust explosion testing, Dianshi High-tech understands the needs of the industry and is committed to providing customized solutions for dust explosion testing for university laboratories, research institutes and enterprises. The company has been deeply engaged in the field of engineering thermophysics, and has spent many years of careful research and development, and launched a number of dust explosion test equipment to provide scientific basis for accident exploration and investigation.

Dianshi High Tech constant volume bomb series products include explosion limit detector, spherical constant volume bomb, cylindrical constant volume bomb, turbulent constant volume bomb and high temperature constant volume bomb, which can comprehensively evaluate the possibility, intensity and safety boundary of dust explosion, help evaluate the risk of dust explosion, and formulate and implement graded control measures.

Explosive limit detector is a professional test equipment for explosive risk assessment of combustible gas, liquid vapor and dust. It can accurately determine the key parameters of dust cloud such as maximum explosion pressure, maximum explosion pressure rise rate, explosion index, lower explosive limit and limiting oxygen concentration. Its typical applications include explosion pressure curve analysis, different fuel minimum ignition energy test, ignition constant determination under different pressures, etc., which provides reliable data support for dust explosion risk assessment.

Fourth, the technical advantages and social responsibility of Point Stone High-tech

Dianshi High-tech not only provides advanced test equipment, but also combines rich industry experience and resources to actively carry out collaborative innovation to help solve the problem of fire prevention and control. The company's self-developed ignition and explosion characteristics test product line can comprehensively evaluate the possibility, intensity and safety boundary of dust explosion, help identify the safety risk of dust explosion at the work site, and formulate and implement graded control measures.

Provide a basis for dust explosion risk identification, assessment and control of Dianshi high volume bomb series experimental equipment can accurately determine the key parameters of dust explosion, help enterprises to identify high-risk areas, develop targeted prevention and control measures.

Dian Shi Gao Ke constant volume bomb series experimental equipment can provide scientific data for accident investigation, help analyze the cause of the accident, and optimize the emergency treatment plan.

The frequent occurrence of dust explosion accidents warns us that there is a long way to go in safe production. The dust explosion characteristic test scheme developed by Dianshi High-tech based on the constant volume bomb experiment system can provide key parameter support for explosion-proof design in chemical industry and new energy. In the future, Dianshi High-tech will continue to focus on "accuracy and safety", help build a safe and stable social environment, and escort industrial safety production.
