Embodiment 1

[0020] A test method for the minimum ignition energy of gas-solid two-phase combustible materials, using a minimum ignition energy test device (such as figure 1 shown) to test the minimum ignition energy of gas-solid two-phase combustible materials. The main body of the device is a spherical test chamber. The vacuum pump and buffer tank are connected to the chamber. The ignition electrode is installed on the flange on the upper side of the chamber. The precision electric One end of the spark generator is connected to the ignition electrode, and the other end is connected to the computer; during the test, the following steps are included: (1) Prepare a mixture of combustible gas cylinders and air cylinders according to the working conditions and enter the mixer; (2) Put combustible dust Place it on the dust blower, turn on the vacuum pump, and evacuate the test cavity. Part of the mixed gas in the mixer enters the cavity, and the other part enters the high-pressure gas storage t...

Abstract

The invention relates to a testing method of the minimum ignition energy of a gas-solid two-phase combustible material. The testing method is mainly used for solving the problem that a minimum ignition energy testing method aiming at gas-solid two phases is not provided in the prior art. By adopting the testing method of the minimum ignition energy of the gas-solid two-phase combustible material,a minimum ignition energy testing device is adopted to conduct minimum ignition energy testing of the gas-solid two-phase combustible material, a spherical testing cavity serves as a device main body,a vacuum pump and a buffer tank are connected to a cavity body, an ignition electrode is mounted on a flange on the upper side of the cavity body, one end of a precise electric spark generator is connected with the ignition electrode, and the other end of the precise electric spark generator is connected with a computer. The problem is well solved through the technical scheme, and the testing method can be used for testing the minimum ignition energy of the gas-solid two-phase combustible material.

Description

technical field [0001] The invention relates to a method for testing the minimum ignition energy of a gas-solid two-phase combustible material. The invention patent is mainly used in the field of production and storage of the three major synthetic materials plastics, rubber and synthetic fibers. The purpose is to prevent the occurrence of fire and explosion under the synergy of the gas-solid two-phase system in the process of production and storage. Background technique [0002] In the production process of the three major synthetic materials, polymer products are obtained from small molecular raw materials through addition polymerization. Small molecular raw materials such as ethylene and butene are all gaseous, and high molecular products are solid. When the concentrations of gaseous materials and solid materials are equal When it is lower than the lower explosion limit, a single component will not cause an explosion accident, but the mixture of the two has the risk of exp...
