On the basis of the test of thermal runaway behavior of water blocking lithium iron phosphate battery, the blocking effect of hydrogel fire extinguishing agent on thermal runaway behavior of lithium iron phosphate battery pack was carried out, and the parameters such as thermal runaway burst time and temperature change rate of lithium-ion battery pack were compared and analyzed. The results show that the cooling depth of the lithium battery pack by water is insufficient and the utilization rate is not high, which cannot effectively block the thermal runaway propagation between the battery packs. The hydrogel fire extinguishing agent can quickly extinguish the open flame, and the surface temperature of the battery is always lower than the thermal runaway critical temperature after the end of spraying, which can effectively block the thermal runaway behavior of the battery pack. The greater the spray rate of the fire extinguishing agent, the more obvious the thermal runaway propagation of the battery pack is prevented, and the large flow of hydrogel fire extinguishing agent can completely prevent the thermal runaway propagation between the battery pack monomers.

Firstly, the influence factors of pipeline failure and the loss type of vapor cloud explosion caused by pipeline leakage were analyzed comprehensively, and the risk value of the center point of the grid was obtained by multiplying the failure probability of the pipeline and the monetary quantified value of the consequence loss in the grid after the vapor cloud explosion caused by leakage at a certain point of the pipeline. Then, based on the principle of superposition field, the risk value of each point in the pipeline segment that had an impact on the center point of the grid was coupled and superimposed to obtain the total risk value of each center point of the grid, and then the risk contour line of the evaluation area was drawn. Finally, the method was applied to a field to draw the risk contour line of vapor cloud explosion of gas pipe network leakage in a certain area. According to the risk acceptability criterion, the evaluation area was divided into special, key and general protection areas, and the corresponding protection area scope was obtained. The results show that the method can accurately evaluate the risk of vapor cloud explosion accident of urban gas pipe network leakage, and make regional risk division more refined and visual than traditional methods, which is helpful to improve the utilization rate of social security protection materials.
