Description
Technical field
The present invention relates to Environmental-protecting dust-removing device metal fittings working process technical fields, and in particular to a kind of Environmental-protecting dust-removing device
With metal fittings dedusting cleaning process.
Background technique
The equipment that dust is separated from flue gas is deduster or cleaner.The performance of deduster is with accessible
Drag losses and efficiency of dust collection when gas flow, gas are by deduster are expressed.Meanwhile price, operation and the dimension of deduster
The difficulty or ease of shield expense, service life length and operational administrative are also an important factor for considering its performance.Deduster is boiler and work
Common facility in industry production.
Cleaning refers to the liquid and solid pollutant for removing workpiece surface, and workpiece surface is made to reach certain cleanliness.Clearly
Washing is also one of very important intermediate auxiliary process in heat treatment production process.It is all add through machine, be heat-treated before workpiece all
Should carry out.Otherwise, the greasy dirt etc. being heat-treated on forward and backward workpiece surface is directly entered heating volatilization and burning in furnace, be easy to cause
Workshop air pollution, workpieces surface condition is also bad, or even influences thermal treatment quality, especially to thermo-chemical treatment and vacuum
Heat treatment.Heat treatment production efficiency and thermal treatment quality can be improved in cleaning, and the related environmental protection with heat treatment, cleaning belongs to cleaning
It is heat-treated scope.
As the Chinese invention patent of Publication No. CN105369270A discloses a kind of metalwork dedusting cleaning process, step
It include: (1) prerinse；(2) dedusting；(3) ultrasonic cleaning；(4) it air-dries；(5) alkali cleaning；(6) it rinses；(7) it dries, by metalwork
Dedusting and cleaning procedure be combined together, and can be dusted during cleaning, be cleaned again than first dedusting
Technique saves time and technical process, is pre-processed using dust removal operation to metalwork, it is possible to prevente effectively from dust meets aqueous fusion
Change, then just sticking not only can remove the dust on metalwork surface in dust removal operation on the surface of metalwork and can also remove
The moisture on metalwork surface avoids and has an impact to the concentration and ingredient of the post-processing liquid of metalwork, influences metalwork
The service life of post-processing liquid, make the solution that makes of alkali cleaning when processing will not be because of ultrasonic cleaning when clear water generate shadow
It rings, improves the effect of cleaning, save time and water resource.
The metalwork dedusting cleaning process of foregoing invention, although saving time and work than the technique that first dedusting is cleaned again
