| titleOfInvention | The tower continuous treater of furfural production six and furfural treatment technique thereof |
| abstract | The tower continuous treater of furfural production six and furfural treatment technique thereof, primarily of primary tower, dehydration tower and treating tower composition, increase de-with light packsly to put, water washing device and aldehyde mud retrieving arrangement, de-with light packs putting comprises lightness-removing column, water cooler and lightness-removing column overhead condenser; Water washing device comprises point aldehyde tank and a water wash column; Aldehyde mud retrieving arrangement comprises water aldehyde tank, recycle-water aldehyde tank and recovery tower.The present invention with light packsly to be put except the Light ends anhydrated in aldehyde decreases the concentration of the Light ends in primary tower by de-, improves primary tower efficiency and refining rate; Utilize water washing device to replace adding alkali neutralization, remove the organic acid in thick aldehyde, improve refining rate 4%, add economic benefit, primary tower waste water aldehyde contenting amount can be reduced simultaneously, reduce environmental pollution; Regularly reclaimed the furfural in aldehyde liquid by aldehyde mud retrieving arrangement, solve the loss that existing raffinate takes the bad recovery of furfural out of, in the foreshot of generation of simultaneously dewatering, furfural is reclaimed, and reduces in Furfural Treating Process and loses, improve furfural yield 5-6%. |
