Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention can be applied to an extremely wide range of applications, not only to piping in buildings and condominiums, but also to the piping in any type of building. [Technical background of the invention and its problems] Conventionally, as a means for cleaning pipes in buildings such as hills, compressing sand of a suitable size into the pipes has been used. There was a cleaning method that physically removed dirt from inside the piping while passing air through it.

However, in the conventional cleaning method mentioned above, cleaning requires an extremely long period of time, causing great inconvenience to building occupants, etc., and the cost of cleaning is extremely high. Because the method involved passing sand through the surface, the cleaning effect was unstable and difficult to predict until after the actual cleaning. Moreover, in the conventional cleaning method, as mentioned above, the method itself is based on mere physical means, so there are inevitably restrictions on the cleaning area, pipe diameter, pipe material, etc. At the same time, new rust forms in the parts of the pipes where the dirt has been scraped off, and furthermore, the cleaning itself with sand damages the inner walls of the pipes, leading to the risk of water leaks, etc. It was like having a

[Object of the present invention]

The present invention is a pipe cleaning method developed in view of the above-mentioned conventional circumstances, and not only eliminates the various defects of the conventional cleaning method, but also completely eliminates any inconvenience for residential areas such as buildings. In addition to making it possible to clean pipes in an extremely short period of time and at low cost without causing any damage, the cleaning method of the present invention itself is called a so-called bio-clinic system, which uses chemical methods to remove rust, limescale, sludge, etc. in pipes. The object of the present invention is to provide a method for cleaning pipes that can be cleaned while reliably dissolving and disassembling the pipes, and that also has a strong rust-preventing effect inside the pipes.

[Summary of the invention]

As mentioned above, the invention is an excellent method for cleaning pipes that can be applied regardless of the type of piping in any building. A water-soluble rust removing solution, neutralized rust prevention solution, and rust prevention solution are used as cleaning media in the method, and the aqueous solutions are sequentially poured into the pipes to remove rust and scale inside the pipes while cleaning the insides of the pipes. Further, while neutralizing the rust removing liquid with the neutralized rust preventive liquid, the rust remover can be immediately drained, and the rust preventive power of the neutralized rust preventive liquid itself is exerted, and In order to completely prevent rust inside the pipe, the above-mentioned rust-preventive liquid is allowed to stay in the pipe for a certain period of time to form a rust-preventive film on the inner wall of the pipe.The second aspect of the present invention is to prevent the rust in the pipes of each of the above-mentioned areas. As a cleaning process in the middle of the cleaning process, a cleaning process using an appropriate acidic cleaning solution used to remove rust, scale, etc. inside the pipe can be mentioned. To support this, one example is the process of adding anti-corrosion agents into elevated water tanks.

Furthermore, in 3rd and 17 of the outline of the present invention, after each pipe cleaning and lower culm spinning described in L, a medium for maintaining rust prevention etc. in the pipes after each cleaning for a certain long period of time is preferably used. An appropriate microbial treatment agent that is effective in various water treatments using airborne bacteria is placed in a building, etc., or placed in a high-rise building (aquarium, etc.). is possible,
It is also possible to add an appropriate physiologically active liquid to promote the action of the microbial treatment agent.

[One embodiment of the present invention]

An embodiment of the present invention will be described below with reference to one drawing.

First, remove the first pipe a7'7+, put an appropriate acidic rust remover solution used for removing rust and scale inside the pipes in buildings, etc., and remove the rust and scale inside the pipe along with the test solution. It's coming. It is convenient for the residence time of the rust removing solution mentioned in Section 42 in the pipe to be about 2 to 13 hours, and even if PHA-1 etc. is used to check whether the test solution has entered the pipe and spread well. good. In addition, the rust removing liquid is removed using the terminal stopper 53e'':q- of each faucet, etc., and the residual rust inside the pipe is removed using a pail, -, -/, etc. KiIT!Z
1. But that's fine. Then, the extracted rust removing liquid neutralizes it; 7, and then drains it.

Next, as necessary, remove residual rust and scale inside the pipe with an appropriate acidic cleaning solution. This is done while removing wood from each end stopper of each faucet, but any remaining rust inside the pipes may also be removed using a patneem or the like.

Next, in order to completely neutralize the acid remaining in the tube and at the same time exhibit the rust-preventing effect, a neutralized rust-preventing liquid is poured into the tube, and then the test solution is removed. The residence time of the test solution in the tube is approximately 3 to 5 hours (ft7).

Further, a rust preventive solution for forming a rust preventive film on the inner wall of the pipe for R time is poured into the pipe f:, and then the test solution is withdrawn.

For example, it is convenient to pour the liquid into the pipe from the first part of the piping of an elevated water tank or the like, and to make the residence time in the pipe 15 hours or more. The anti-corrosion liquid is removed from the end stopper of each faucet or the like.

Then, if necessary, there comes a step of performing bone washing similar to the bone washing described above. The bone washing is performed by ensuring that residual rust, etc. inside the pipe is removed using water pressure or the like.

In addition, after the above-mentioned rust prevention liquid removal process or bone washing process,
As a post-treatment for the rust-preventing treatment inside the pipe that has deteriorated at one end, a step L may be adopted in which a rust-preventing liquid is poured into an elevated water tank placed in the second or second part of the building.

In addition, during each of the above-mentioned cleaning steps, after each liquid is withdrawn, the cleaning status inside the tube is confirmed and photographed using an endoscope.

In the cleaning method according to the present invention,
1iiJ After the end of each cleaning process, an appropriate microbial treatment agent that is effective in various water treatments with aerobic bacteria is used as a medium to retain rust etc. in the pipes after cleaning for a certain long period of time, and Alternatively, an appropriate physiologically active liquid may be used to promote the action of the microbial treatment agent.

The actual use of the microbial treatment agent is 1. For example, if the microbial treatment agent is used in a building at a ratio of 100 ec to 1 ton of water, and in a packaging state that allows water to seep into the inside of the agent. It may be placed in an elevated water tank, etc.

The type of microbial treatment agent mentioned above is not particularly specified; for example, it includes enzymes that digest each component contained in various wastes, microorganisms that secrete these enzymes, and digests organic and inorganic compounds. The main ingredients are bacteria that cause deterioration, and mutant bacteria that are made by mutating and adapting selected natural microorganisms using various methods.
