The present invention relates to a kind of gas cooling device more particularly to a kind of exhaust gas coolers.
Background technique
Ammonia sulfur cycle washing method sulfur removal technology is one of coking production conventional process, and the tail gas of the process flow cannot be direct
It is discharged into atmosphere, in the raw coke oven gas pipeline before primary cooler need to be entered, circular flow.Due to exhaust temperature height, it is directly entered famine
When gas piping, will affect the flow regime of gas-liquid mixture in pipeline, therefore a tail is usually set on inhaling gas piping
Gas Cooler sprays cooled exhaust gas using tar ammonia mixture.
In traditional exhaust gas cooler, spray is arranged in cooler side centre in gas inlet setting at the top of equipment
Pipe is spilt, spray head is set at the top of spray line, after coal gas enters, tar ammonia sprays cooled exhaust gas from spray head.Using this kind of structure
Exhaust gas cooler, when tail gas is entered inside cooler, instantaneous pressure reduces, volume increases, contact mass transfer decreased effectiveness, practical to transport
Find that cooling effect is bad after row.
Improved exhaust gas cooler air inlet pipe is changed to tangential feed, and tail gas is transported after entering cooler along body inner wall circumference
It is dynamic, the cyclonic effect of part is generated, although contact mass transfer is enhanced, the spray pressure of tar ammonia is in actual operation
Be it is unstable, when spray pressure is big, tar ammonia can be entered in air inlet pipe, countercurrently arrived sulfur recovery workshop section, not only caused pipe
Road blocking, and workshop section's medium is polluted, it brings about great losses to the production of the workshop section.And tangential feed will increase applying for equipment
Work difficulty.
