Abstract
The clean method of this inner-walls of duct of this disclosure of the invention, it is the ice slurry using 85% and concentrations above, in the pipeline for being cleaned ice slurry press-in needs using screw pump, the friction and scraping of the ice slurry post and inner-walls of duct that are formed by the ice slurry of high concentration, using caused frictional force between ice slurry post and inner-walls of duct and the shearing force of ice slurry post, the incrustation layer of inner-walls of duct is removed.The method of this cleaning pipeline is that segmentation is carried out, and one section of achievable length is hundreds of meters of distances to several kms.The valve one end set according to pipeline system itself imports high concentration ice slurry, from the ice slurry and the mixture of incrustation after other end discharge cleaning.The producing equipment of the ice slurry of this Invention Announce and the technology for producing high concentration ice slurry, I takes charge of and grasped, as long as with electricity and water, not limited by other external conditions.This clean technologies are simple to operate, and cost is cheap, are the technologies being worthy to be popularized.
Description
Technical field
Disclosed by the invention is a kind of clean method of inner-walls of duct, this clean method rely primarily on high concentration ice slurry and
Screw pump is realized, so that inner-walls of duct recovers material surface itself.
The invention belongs to processing engineering technology field.
Background technology
At present, municipal water supply and sewerage pipeline, heating network, air-conditioner water system pipeline, industrial production are various is used for pumped (conveying) medium
Pipeline and oil long range transfer line etc., due to much time using, its inner-walls of duct can be formed a lamination dirt layer or
Different degrees of deposit.Pipeline is not cleaned for a long time, internal diameter of the pipeline contraction can be caused to diminish, fouling is deposited seriously, pipe
Road crushing increases year by year, and pumped (conveying) medium flow is severely impacted, while the incrustation of inner-walls of duct is entrainment of bacterium etc..This is not only
The quality of pumped (conveying) medium is directly affects, the also breeding for all kinds of mushrooms provides place, promotes pipeline corrosion to aggravate.
And to municipal water supply duct cleaning it is even more one very necessary, it can not only improve the transfer efficiency of pipeline, reduce energy
Consumption, and pipe scale can be removed, secondary pollution is released, quality of increasing water quality, ensures that the people are physically and mentally healthy.
Current inner-walls of duct clean method has artificial cleaning, chemically cleaning, high-pressure water jet to clean, carbonated drink pulse cleaning and
PIG cleanings etc..
But above-mentioned clean method is in addition to chemical products to be used or water under high pressure contact, it is also necessary to pipe is dismantled, both
It is dangerous and waste time and energy.
In the case, the present invention discloses a kind of new duct cleaning method, i.e., using high concentration ice slurry cleaning inner-walls of duct
Method.
The content of the invention
This clean method of this disclosure of the invention, it is the ice slurry using 85% and concentrations above, using screw pump by ice slurry
In the pipeline that press-in needs clean, pass through the friction and scraping of the ice slurry post and inner-walls of duct of the ice slurry formation of high concentration, utilize
The shearing force of caused frictional force and ice slurry post between ice slurry post and inner-walls of duct, the incrustation layer of inner-walls of duct is removed.
The method of this cleaning pipeline is that segmentation is carried out, and one section of achievable length is hundreds of meters of distances to several kms.According to
Valve one end that pipeline system itself is set imports high concentration ice slurry, from the ice slurry after other end discharge cleaning and the mixing of incrustation
Thing.
This clean method of disclosure, advantage are as follows：
1) compared with existing duct cleaning method, no longer import chemicals, avoid the neutralization of the chemicals after cleaning
And discharge, in the absence of secondary pollution situation；
2) to be compared with existing duct cleaning method, the ice slurry after being cleaned using this method can be directly discharged to sewage network,
In the absence of secondary pollution situation；
3) compared with existing duct cleaning method, without being dismantled to pipe, more do not need water under high pressure and PIG equipment to enter pipeline
Inwall, save time and cost；
4) compared with existing duct cleaning method, the producing equipment of ice slurry and the technology for producing high concentration ice slurry, I takes charge of
Through grasping, as long as with electricity and water, not limited by other external conditions；
5) compared with existing duct cleaning method, clean method is simple to operation.
Brief description of the drawings
Fig. 1 is high concentration ice slurry cleaning pipeline schematic diagram；The ice slurry of 1.85% or more concentration, 2. ice slurry storage containers,
3. screw pump, 4. ice slurry imports, 5. pipelines to be cleaned, 6. ice slurry posts, incrustation layer in 7. pipelines, the outlet of 8. ice slurries.
Specific implementation method
This invention is the ice slurry using 85% and concentrations above, is pumped into using screw pump in pipeline.Specific implementation method
It is as follows：
Screw pump（3）From ice slurry storage container（2）The middle ice slurry by 85% or more concentration（1）The ice set by pipeline one end
Slurry inlet（4）It is pumped into pipeline to be cleaned（5）It is interior, the ice slurry of 85% or more concentration（1）In pipeline to be cleaned（5）Interior flowing, gradually
Form ice slurry post（6）And move ahead in this way, incrustation layer in the frictional force scraping pipeline of ice slurry post（7）, removed repeatedly after scraping
Incrustation layer in pipeline（7）Deng debris, mix with ice slurry and exported by ice slurry（8）Flow out and discharge.
