Embodiment Construction
[0018] A method for extinguishing the torch and recovering the heat of the torch gas according to the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] A kind of method that can extinguish the torch and recover the heat of the torch gas according to the present invention, such as figure 1 As shown, it includes the following:
[0020] (1) Under normal working conditions, the flare exhaust gas is discharged to the recovery system for direct combustion and heat recovery, and then the combustion flue gas is discharged into the atmosphere;
[0021] Specifically: the torch exhaust gas is passed into the incinerator and mixed with gas and combustion-supporting air at about 1100 ° C to perform a high-temperature combustion decomposition. At this temperature, the organic components and other combustible components in the torch exhaust gas are completely decomposed into H 2 O and CO 2 . Then the high-tem...

The invention provides a method capable of extinguishing a torch and recycling heat of the torch gas. According to the invention, in normal working conditions, the torch-emitted gas is discharged to a recycling system to be directly burnt while the heat is recycled, then the burnt smoke is discharged to the atmosphere; and in the case of an accident, the pipeline is switched, and the torch-emitted gas is discharged to a torch gas igniting system to be directly burnt and discharged. The method provided by the invention solves the problem that the torch-emitted gas of the petrochemical industry and coal chemical industry is so much that safe utilization cannot be realized currently, and can extinguish the torch and recycle the waste heat of the torch gas and ensure safe discharge of the torch gas in the case of an accident of the petrochemical device as well as recycling of the waste heat of the torch gas in normal working conditions. The method provided by the invention has the advantages of safety, reliability and reasonable configuration as well as outstanding characteristics in energy conservation and emission reduction.
Description
technical field [0001] The invention relates to the heat recovery and utilization technology of the torch gas, in particular to a method which can automatically switch to incinerate the torch exhaust gas in an accident state, and at the same time recover and utilize the heat of the torch exhaust gas in the working state. Background technique [0002] At present, the petrochemical industry and the coal chemical industry generally adopt the process of directly discharging the torch gas into the atmosphere after being burned by the torch. Due to the complex composition of flare exhaust gas and the large flow fluctuation range, it is generally difficult to directly burn and utilize flare exhaust gas. The exhaust gas containing a large amount of organic components is completely burned through the torch, and a large amount of high-temperature flue gas is generated after combustion, which is directly discharged into the atmosphere. Therefore, the flue gas after torch combustion ge...
