[Abstract]:Based on the practical experience in identifying the danger of combustible gas released by water, a fully automatic instrument for detecting the risk of combustible gas released by water is developed. This paper introduces the structure design, working principle and key technology of the tester. The micro negative pressure difference feedback collection technology is used to realize the accurate collection and volume detection of the gas released by water in chemical products, and the automatic water injection is used to realize the accurate control of the volume of water injection, thus avoiding the influence of the volume of water injection on the detection of the gas release rate. The degassing rate of 88% mancozeb and magnesium-aluminum powder was measured to verify the accuracy and stability of the equipment. The effect of water temperature on the rate of combustible gas released from chemical products by water was studied. The results showed that with the increase of water temperature, the reaction rate was accelerated, and the gas release rate of magnesia-aluminum powder was gradually increased.
