Explosion reason and safety solving measures of bulk cement tank carThis paper analyzes the properties of bulk cement tanker explosion, summarizes its main reason is bulk cement tanker production quality is not up to the strength requirements, safety measures, failure workers neglect or lack of experience, thus aiming at the lightweight bulk cement tanker design and production process problems and puts forward the corresponding solution it measures, powder material truck production enterprises to concern and attention.Cement tank and cement tanker only one word, function, style but a world of difference between the two. Cement tank is the storage equipment of bulk cement, cement tank car is the transport equipment of cement concrete. One is fixed, and the other is mobile.1. Dust Explosion AnalysisDust explosion refers to the explosion of combustible dust which is suspended in the air and touches the fire source such as open flame or electric spark. The explosion process is accompanied by high pressure and high temperature combustion, and it is easy to produce two explosions, which belongs to chemical explosion. There are three necessary conditions for dust explosion: combustible dust suspended in air, sufficient air and oxidizer, fire source (including electric spark); dust explosion can occur only when three conditions exist at the same time. Whether the bulk cement tank car is dust explosion, it is necessary to determine whether the medium in the tank belongs to combustible dust.By referring to relevant information, seven kinds of material dust is defined as combustible dust: metal, coal, food, feed, synthetic materials, family by-products, forestry category.

Explosion of bulk cement tank car and its solutionin view of the causes of explosion accidents of bulk cement tank cars, manufacturers and designers should first consider how to improve the safety of bulk cement tank cars themselves. The author thinks that improving the safety of bulk cement tank car can be done from the following aspects, and its solution measures are as follows:(1) the strength of tank: the steel produced by the regular factory should be avoided in the production process, and the local thinning of the plate should be avoided. After the completion of the production, the tank will be pressurized test.(2) install two sets of setting pressure (editor note: setting pressure is the opening pressure that the safety valve is set in cold test) different safety valve, prevent safety valve repeatedly action damage, one set pressure is higher than the maximum working pressure, and discharge capacity is as large as possible.(3) for the use of the gas source of the bulk cement semi trailer, it is possible to rationally design the air source power device, so that the maximum pressure generated by the maximum power can not exceed the maximum load pressure of the tank.(4) using the pressure release type material cover, the maximum pressure of the material cover is lower than the maximum load pressure of the tank, and when the pressure in the tank exceeds the maximum pressure value of the material cover, the cover can automatically discharge and reduce the pressure.(5) increase the requirement of transport medium to avoid dust explosion when transporting combustible powder material.
