Abstract

The invention relates to a method for evaluating maximum combustible gas concentration of an oxidation reactor, which mainly aims at solving the problem of failure to effectively detect the burning and explosion danger of the oxidation reactor in the prior art. The method for evaluating the maximum combustible gas concentration of the oxidation reactor comprises an oxygen mixer, a temperature-controllable reactor and a vacuum pump, wherein an oxygen pipeline and a combustible gas pipeline are respectively connected with the oxygen mixer; flame-retardant explosion-proof filler is charged into the oxygen mixer; an exit of the oxygen mixer is provided with two paths, one path is connected with an entrance of a metering pump, and the second path is connected with an exit of the temperature-controllable reactor; an exit of the metering pump is connected with an entrance of the temperature-controllable reactor; the temperature-controllable reactor is provided with a safety valve, a rupture disk and at least one thermocouple, each thermocouple is connected with a computer, and the vacuum pump is connected with the exit of the temperature-controllable reactor. By adopting the technical scheme, the method has the advantages that the problems are well solved, and the method can be used for evaluating the maximum combustible gas concentration of the oxidation reactor.

Description

technical field [0001] The invention relates to an evaluation method of the highest combustible gas concentration in an oxidation reactor. Background technique [0002] Oxidation reaction is an exothermic dangerous chemical reaction. When combustible gas and oxygen react in the oxidizer, if the reactor temperature, material residence time, oxygen concentration and initial pressure are not well controlled, complete oxidation is likely to occur (ie Combustion), leading to the overheating of the reactor, and then a combustion and explosion accident. [0003] CN201510185390.9 relates to a device for measuring gas phase combustion and explosion characteristics in the reaction process, including reactor, ignition head, temperature and pressure sensor, feeding system, temperature and pressure acquisition system, ignition control system and external circulation heat extraction system. [0004] Existing detection methods cannot meet the requirements of working conditions, and the de...
