Abstract
The present invention discloses a method for descaling a pipeline with high-pressure air or water and protecting the wall of the pipeline, and relates to a method for removing rust stains and scale in a water conveying pipe, a water supply pipe, a gas pipe and an oil pipe and coating a wall protecting coating. In the method, the high-pressure gas or water enters the pipeline needing to be cleaned through a connecting pipe after treatment of pressure stabilization, purification and cyclone and carries out treatment on the inner wall and scale of a pipeline, and then, rubs and impacts the inner wall and the scale of the pipeline with sand so as to clean the pipeline; then, the pipeline is cleaned by the revolving air and water; finally, with the revolving air, food resin is uniformly coated on the inner wall of the pipeline to form a coating film protecting the inner wall of the pipeline. The present invention has the advantages of short time for descaling and wall protection, less energy consumption, high speed of construction progress, high efficiency, no pollution, no need of knocking walls and drilling walls during working so that original decoration is not damaged, and less influence on users, particularly further ensuring the water flow quantity and the water quality of domestic water supply pipelines.
Description
Technical field
High pressure gas, waterpipe scale removal and wall protecting method relate to feed pipe, feed pipe, gas pipe, petroleum pipeline are removed the interior rust staining of pipe and the method for fouling and coating wall protecting paint.
Background technology
Feed pipe and air supply pipe that existing live and work adopts mostly are the zinc coating iron pipe, can produce rust staining and fouling after the use of long period on inside pipe wall, have both influenced and have supplied water and air feed, make that again water supply quality degenerates, and influence the healthy of people.In order to remove pipeline inner rust spot and fouling, adopt 1. chemical cleaning methods at present usually, adopt chemical agent to pour in the pipeline, deposit a period of time, make that the fouling in the pipe is softened, come off, water is clean pipe flushing then.2. vibrating method, by pipeline is vibrated (as, knock pipeline) rust staining and fouling in the pipeline are come off, water is clean pipe flushing then.3. the method for mechanical curettage generally is used for large-diameter pipe, and the dirt that adopts machine tool will tie on inner-walls of duct strikes off, and water is rinsed the back well and adopted the cement mortar retaining wall to handle.Said method only is that dirt is handled, scale removal difficulty height, and the required time is long, and the water yield that is used for pipe blow-through is big, and especially chemical cleaning method can produce new harm as chemical agent not being rinsed well.Chemical cleaning method, after the vibrating method scale removal, inside pipe wall is not taked the retaining wall measure, so also can get rusty and fouling in the pipeline soon, time one is long, and pipeline just can not normally use, as changing old pipeline, to resident or the user of unit, just decorate inconvenience more owing to will destroy.Handle though the method for mechanical curettage is carried out retaining wall to inside pipe wall after scale removal, the cement mortar thick coating has dwindled caliber, has reduced the conveyance power of water of pipeline.Have at present and adopt gases at high pressure to carry out eliminating sludge in pipe, but it must be earlier to heat-treating in the pipeline, energy consumption is big like this, especially the pipeline thermal energy consumption of long distance also is difficult to the effect that reaches desirable and this method difficulty of construction height more greatly, long construction period, inefficiency can produce a large amount of dirt ashes, contaminated environment in the work progress, the only small-caliber pipeline that is suitable for, so few people is used.
Summary of the invention
Deficiency at above-mentioned existing rust removing and contaminant releasing method, the inventor has proposed a kind of to removing rust staining and fouling with pipeline through studying for a long period of time, and on inside pipe wall, film, make pipeline unimpeded, no longer fouling, get rusty, and less energy consumption, the efficiency of construction height is applicable to high pressure gas, waterpipe scale removal and the wall protecting method of the pipeline cleaning of various calibers.
The present invention realizes in the following manner: adopt high pressure gas, water and sand grains that pipeline inner rust spot, fouling are removed, then with food level resin to the inner-walls of duct retaining wall of filming.Sand grains adopts quartz sand or iron sand grain or steel sand grain.The inventive method the time looks pipe condition is set high-pressure gas pressure and through voltage stabilizing in work, purify, the back adds clear water, make high pressure gas, the water generates rotation, the high pressure gas of rotation, water is earlier to handling in the pipeline, ponding in the drain, make the interior air-flow of pipeline unimpeded, be with sand grains in pipeline, inside pipe wall and fouling constantly to be clashed into after adding sand grains, friction makes rust staining and fouling pulverize, come off, then use high pressure gas, water cleans up inner-walls of duct, pulverizes, rust staining that comes off and fouling are with by high pressure gas, water is taken the pipeline that is cleaned out of and is entered retracting device with sand grains.With gases at high pressure tube wall is dried up again after rust staining and removal of deposit are intact; food level resin with the gases at high pressure band then and in rotary course, be coated in formation one deck cuticula on the inside pipe wall equably; apply the end back and by gases at high pressure cuticula is dried up, the protection tube inwall no longer gets rusty it, fouling.
Advantage of the present invention is fairly obvious, adopts high pressure gas, water and the sand of rotation clean rust staining on the inside pipe wall and removal of deposit, and food level resin is coated on the inside pipe wall equably, forms cuticula protection pipeline.The time weak point that whole scale removal of the inventive method and retaining wall work are required, power consumption is few, construction speed is fast, the efficient height, can not produce pollution, be applicable to the cleaning of the pipeline of various calibers, and work the time does not need to strike wall cutter wall and destroys original decoration, influence to the user is little, especially more can guarantee the water yield and water quality for life with feed pipe.
Description of drawings
Accompanying drawing 1. is workflow diagrams of the inventive method embodiment.
The specific embodiment
In conjunction with the accompanying drawings the inventive method is further described.
At first according to being determined high pressure gas by the situation of cleaning pipeline, the pressure of water, and by voltage-stablizer to its voltage stabilizing, by clarifier gases at high pressure are dewatered except that oil purification, add clear water then, through voltage stabilizing, the high pressure gas of rotation, water enters by in the cleaning pipeline by tube connector, at first inner-walls of duct and fouling are handled, then the steel sand grain is joined the high pressure gas of rotation, in the water, the high pressure gas of rotation, the water band sand grains inner-walls of duct is constantly clashed into, friction makes rust staining, fouling is pulverized, come off, then use high pressure gas, water cleans up inner-walls of duct, pulverizes, the rust staining that comes off, fouling is with high pressure gas, water is taken the pipeline of being cleared up out of and is entered retracting device with sand grains.With gases at high pressure inner-walls of duct is dried up then; at last food level resin is joined in the gases at high pressure of rotation; food level resin is liquid; under driving, the gases at high pressure of rotation are coated in equably on the inner-walls of duct; to be filmed by the gases at high pressure of rotation and dry up in coating end back, form one deck cuticula on inside pipe wall, protect inner-walls of duct in water delivery constantly or gas transmission; no longer get rusty fouling on the inner-walls of duct.
