Description
Technical field
The present invention relates to a kind of cleaning method, and in particular to a kind of rectifying column ripple packing cleaning method.
Background technology
Rectifying column ripple packing is common fine chemistry industry equipment, is the core component of rectifying column, is produced in fine chemistry industry
During, due to the difference of raw materials for production, raw material variety is various, easily pollutes rectifying column ripple packing, causes rectifying column to block,
Cannot normally run, cause damp production, energy resource consumption sharp increase, production efficiency lowly, conventional solution is to change dirty
The ripple packing of dye blocking, and the ripple packing changed is net with burning.
Although changing ripple packing simple possible, cost is acute big, at least tens thousand of units, at most hundreds thousand of units, economically
Very do not calculate.And with burning peace and quiet ripple packing, although simple and fast, but larger is damaged to ripple packing, Jing after burning, ripple
Stricture of vagina filling intensity is substantially reduced, and ripple shoals, and causes rectifiying plate coefficient to greatly reduce, and efficiency of rectification tower is reduced, and ripple is filled out
Material Jing after baked wheaten cake process, scrap again it is many, about between 30% ~ 50%, hence it is evident that lose more than gain, enterprise can be greatly increased
Production cost, weakens the competitiveness of enterprise.Therefore, being badly in need of one kind can carry out cleaning in room temperature, use up in cleaning process
Amount does not damage the cleaning method of ripple packing.
The content of the invention
It is an object of the present invention to be directed to problems of the prior art, a kind of rectifying column ripple packing cleaning is proposed
Method, realization are cleaned in normal temperature environment, the ripple for not damaging ripple packing, the intensity for not reducing ripple packing, are not subtracted
Lack rectifiying plate coefficient, do not reduce efficiency of rectification tower, it is cost-effective.
To achieve these goals, the technical solution used in the present invention is：
A kind of rectifying column ripple packing cleaning method, comprises the following steps：
The first step, abluent is prepared by the composition of following weight portion：
10 ~ 30 parts of soda powder,
5 ~ 40 parts of sodium hydroxide,
4 ~ 30 parts of DBSA,
1 ~ 20 part of sabinene,
1 ~ 15 part of aromatic hydrocarbon,
1 ~ 5 part of carboxymethyl cellulose；
Second step, by the abluent made in the first step add clear water in, stir, then ripple packing to be cleaned be put into
In soak, 24-30 hours under room temperature, are soaked；
3rd step, the ripple packing after immersion is cleaned down with wire brush, then rinsed with clear water；
4th step, cleaned ripple packing is classified according to former specifications and models, burst, point direction and layering are folded, and with thin
Iron wire is tied, shaping, point tower concentrate stand-by；
5th step, tied up, orthopedic ripple packing reinstalls rectifying column and resumes production.
In the first step, the composition of abluent includes the composition of following weight portion：
15 ~ 25 parts of soda powder,
20 ~ 30 parts of sodium hydroxide,
10 ~ 20 parts of DBSA,
5 ~ 15 parts of sabinene,
6 ~ 10 parts of aromatic hydrocarbon,
2 ~ 4 parts of carboxymethyl cellulose；
In the second step, the weight ratio of abluent and water is 1:100.
In the second step, the time of immersion is 27 hours.
After the completion of the ripple packing cleaning, filtered after the waste liquid for producing is clarified in cleaning process, filtering residue is used as fuel
Burn, filtrate is discharged Jing after processing and reach environmental protection standard.
As a result of above-mentioned technical proposal, the invention has the beneficial effects as follows：
The present invention does not damage the ripple of ripple packing, does not reduce ripple due to without high-temperature process, carrying out in normal temperature environment
The intensity of filler, does not reduce rectifiying plate coefficient, does not reduce efficiency of rectification tower, is fully achieved the effect of new ripple packing, saves
Cost, environment-friendly high-efficiency.
Rectifying column ripple packing dirt is mainly Acidic organic matter, and soda powder can neutralize the acidic materials in dirt, hydrogen-oxygen
Change sodium can remove and be covered in the materials such as cured matter, the oils and fatss on filler surface, and DBSA is anionic surfactant,
Organic substance in activation dirt, sabinene and aromatic hydrocarbon act primarily as and soften and dilute the gelatinizer in dirt, and carboxymethyl cellulose is weak
The materials such as acid form of cation exchanger, the neutral or alkaline protein of separable dirt.Abluent and water press 1:100 ratio is dilute
Release, filler is put into into the abluent after dilution, carry out the dirt adhered on effective ingredient in abluent and filler fully anti-
Should.
