Description
Technical field
The invention belongs to pipeline cleaning technical field, more particularly, to a kind of anhydrous cleaning of heavy caliber long range pressure pipeline
System and its application method.
Background technology
Water is the necessity of life and production, if water quality does not reach corresponding requirement on the living conditions, will influence people
The health of body；Industrially water quality does not reach respective standard, will to industrially being caused damage, be this water quality standard formulation and
Social all trades and professions are closely bound up.80 years this periods so far of 20th century, the urban water supply cause of China has obtained huge
Development.The existing GB5749-2006 standards for drinking water quality of China is by the Ministry of Public Health, the Ministry of Construction, Ministry of Water Resources, territory money
Source portion and State Environmental Protection Administration propose, are formulated in the case where Standardization Administration of China organizes and leads, by Chinese disease
Prevention center is responsible for drafting, by the national standard of Ministry of Public Health's management through specialized department, in the formal implementation in the whole nation on July 1st, 2007
, new standard regulation water quality detection project increases to 106 by original 35, wherein on healthy influential index（Such as lead,
Arsenic, agricultural chemicals, microorganism etc.）Account for 81%.Feedwater piping only through installation rinses the water for being just available for out water quality reaching standard completely, institute
To say that pipe flushing occupies very important status in city supply water pipeline engineering.
Feedwater piping passes through long-play, pipeline meeting corrosion and scaling, impurity deposition and compression strength reduction, when in pipeline
When water (flow) direction, pressure jump, under in-pipe flow effect, easily there is " yellow water ", " black in inner-walls of duct fouling partial exfoliation
Water ", or even booster, cause Water Quality in Networks secondary pollution and water failure；Pressure sewage conduct passes through long-play,
Corrosion and scaling, impurity depositional phenomenon can be produced；Therefore plumbing pressure pipeline must periodic cleaning.Health organization expert alerts：
Rust water is not only produced using running water tube wall for many years, hinders to be even more to shelter evil people and countenance evil practices in current, tube wall, hoards various miscellaneous bacterias, micro-
The toxic heavy metals such as algae poison, arsenic, cadmium, mercury are measured, as current are absorbed by the body little by little, accumulation inherently causes various long afterwards
The disease of various kinds.Running water and the various problem Producing reasons of other pressure pipe networks have many kinds, pass through correlative study unit
Investigation thinks that reason mainly has the following aspects:1) when output water is with corrosive substance or pipeline (including user's branch
Pipeline) service life is long, and inner-walls of duct will corrosion and scaling, deposition；Initial stage is when water velocity, direction or hydraulic pressure in pipeline
When undergoing mutation, the water quality deterioration of short time is will result in, the rising of the indexs such as concentration of iron, turbidity, colourity, latter stage even meeting occurs
Cause to supply, impeded drainage, have a strong impact on production and living；2) new pipeline installation construction is lack of standardization, does not do interior anti-corrosion, operation preshoot
Wash, sterilize it is not thorough；3) when water source or undrinkable water pipeline are connected, anti-pollution measure is not taken, unqualified water is flowed into pipe network
It is interior；4) some pipelines, valve, water meter long period of soaking also easily cause different degrees of pollution to pipe network water in water；5) it is secondary
Water facilities, such as storage cistern, water storing tank are for a long time without cleaning and sterilizing；6）Feed pipe is as water delivery medium, throughout the year and water
Or slowly drained soil contact, because of chemical reaction or the certain corrosion of electrochemical reaction effect generation, also because inner wall of metal tube is by water enchroachment (invasion)
Suspension precipitation and iron bacteria, the breeding of algae in precipitation of calcium carbonate in erosion, water, water etc. turn into the master of pollution pipeline
Cause.Using not clean for a long time makes various sediments silts in pipeline form block.
The widely used conventional pipelines cleaning of water supply industry mainly has mechanical pipe cleaning, waterpower clear at home at present
Wash and rush cleaning etc. with intelligent pulse cyclone.Mechanical cleaning process is, using steel wire rope etc., it is dragged back and forth in feed pipe with external force
Dynamic, the method is applied to remove the feedwater piping with hard incrustation, is commonly used to the pipeline that caliber is less than 450mm, pipe cleaning
Length is up to 100 ~ 250m, and the shortcoming of this method is that damage original to pipeline is larger, it is necessary to disconnected pipe and cut off the water, and meets pipeline attached
Part etc., constructional difficulties；Waterpower ablution is that pipeline is rinsed with the high-velocity flow of certain hydraulic pressure, it is adaptable in feedwater piping
Wall only has soft incrustation, not yet forms harder growth ring, not good to harder growth ring developing result, and flow velocity is shadow
The most important parameter of Xiangshui County's power flush efficiency, for large diameter pipeline, raising flow velocity is more difficult, and waterpower cleaning performance is paid no attention to
Think, and water consumption it is very big the problems such as.
In order to solve the problem of prior art is present, people have carried out long-term exploration, it is proposed that miscellaneous solution
Scheme.For example, Chinese patent literature discloses a kind of water supply line cleaning device [application number：201620696966.8], at least
Including high-pressure water pipe, bearing, bearing block, link, connecting tube, pressure stabilizing cavity, cleaning head, discharge outlet and cleaning post, the height
Pressure pipe is fixedly connected with the bearing, and the bearing is connected with the bearing block, and the connecting tube passes through welding ends and institute
State bearing block connection, another end is connected with the pressure stabilizing cavity, and the high-pressure water pipe, bearing, bearing block, connecting tube and it is described surely
Pressure chamber is sequentially communicated, and the link lower end is fixedly connected with the bearing block, and upper end is fixedly connected with the pressure stabilizing cavity, described
Clear up post fixedly sleeved on the link.
