Description

technical field

[0001] The invention relates to the field of cooling for industrial production, in particular to a cooling medium dispersion device. Background technique

[0002] In industrial production, many fields involve the use of temperature to control the progress of flue gas reactions.

[0003] Taking the production of acetylene as an example, the temperature for terminating the reaction is 1300°C, which requires the flue gas temperature to be lowered to an appropriate range in the heat exchange furnace. At present, this process is realized by spraying into quenching water, however, there are following problems in this way:

[0004] 1. First of all, a large amount of quenched water injected into water vapor causes changes in the composition of the flue gas, causing a sudden increase in the flue gas flow rate, which not only affects the quality of acetylene, but also increases the processing pressure of downstream equipment. Corrosion caused by equipment is also mor...
