Description
Technical field
The utility model relates to rectifying column deslagging technique field, specifically refers to slag-draining device at the bottom of a kind of rectifying tower.
Background technology
Rectifying column is a kind of tower gas-liquid contanct equipment for rectifying conventional in petrochemical industry, has plate column and packed tower two type.In chemical process, the impurity such as impurity, catalyst fines, the polymerization of unsaturated hydro carbons, the powder of ceramic packing that raw material is carried secretly, in the process of rectifying, constantly can accumulate in rectifier bottoms, finally cause reboiler and tower bear building-up dirt and column plate to block.Therefore, in order to ensure normal distillation operation, need to clear up in time when dregs at the bottom of tower are accumulated to a timing time, but due to the easy coking of some materials in distillation process, thus bring difficulty to scarfing cinder work.
At present, existing scarfing cinder means normally adopt the following two kinds mode to carry out scarfing cinder work:
1, certainly clear slag, this kind of mode normally arranges a scum pipe in rectifier bottoms, regularly opens for discharging dregs at the bottom of tower and impurity.But, this kind is from clearing slag mode in practical operation, consider the loss of material, the amount of each deslagging is all little, makes the motive force of deslagging little, causes the fluid near slag-drip opening to be close to and remains static, a large amount of dregs cannot be taken out of, deslagging weak effect, end slag easily in slag-drip opening deposition, causes scum pipe to block.
2, slag taken out by vavuum pump, and this kind of vavuum pump is taken out slag mode taking out in slag process and easily blocked vavuum pump, and deslagging efficiency is low, and equipment replacement maintenance is frequent, and operating maintenance upkeep cost is high.
In addition, except above-mentioned two kinds of scarfing cinder modes, existing people proposes the scarfing cinder mode upper two kinds of modes combined, as " patent No. is 201220679212.3, patent name is slag-draining device at the bottom of rectifying tower " Chinese utility model patent, comprise the scum pipe be connected with the slag-drip opening at the bottom of rectifying tower, described scum pipe connects vacuum chamber, described vacuum chamber connects vavuum pump by vacuum lead, described scum pipe is provided with stop valve, described vacuum lead is provided with valve, described vacuum chamber connects vacuum meter, described vacuum chamber is provided with observation window.This kind takes out from clearing slag and vacuum the scarfing cinder mode that slag is combined; solve above-mentioned from clearing the problem that slag is thorough, scarfing cinder efficiency is low and vacuum blocks, but also exist significantly not enough, one side changes inconvenience; need to shut down and change; cause damage, on the other hand, the dregs of removing directly abandon; can not recycle; material loss is large, and cost is high, and environmental pollution is serious.
