Generally, pipes used for heat exchangers such as water supply, drainage, or boiler in houses and various industrial facilities and factories are used for long time, and due to the interaction with hardness components and microorganisms included in the piping water, Impurities such as corrosion, scale and slime are accumulated. When the impurities are deposited on the inner wall of the pipe, the flow of the fluid in the pipe is disturbed, and metal oxides such as rust and harmful impurities such as bacteria are accumulated, thereby causing odor, water taste, suspended substances and chromaticity. Will influence. In addition, in the piping of a heat exchanger such as a boiler, efficiency of heat transfer due to scale and the like is lowered, and efficiency of cooling and heating is lowered, thereby causing energy loss to increase. Also, since it is left to stand for a long time, In order to solve these problems, it is necessary to periodically clean and manage an effective piping cleaning device because time and cost are required.

In the case of the Korean Patent No. 10-0821715, it is assumed that the auxiliary equipment such as a compressor, a pressurizing pump, and an air tank, which pressurizes the air, In the case of the Korean Patent No. 10-1261316, there is a limit to the complexity of the apparatus and the practicality of the operation due to the complicated piping structure such as apparatus for generating fine bubbles, air piping, washing water piping, detergent supply tank and piping There is a limit to cleaning piping that is difficult to access.

According to the present invention, cleansing water prepared for effective piping cleaning is prepared by using hydrochloric acid to make cleansing water containing acid concentration of about 2 ~ 3 and salt concentration of 5,000 ~ 10000 ppm .

In the present invention, in order to supply the washing water to the electrolytic apparatus, when the self water pressure of the water in the pipe is large, the washing water is naturally supplied by the pressure difference formed in the injector and supplied. The washing water is directly supplied to the electrolytic apparatus by using the washing water supply pump. In each case, the direction of supplying the washing water is changed through the switching valve in the washing water direction and the washing water is supplied to the electrolytic apparatus So that it can be supplied.

According to the present invention, there is provided a method for simultaneously forming a dissolution action by cleansing water, an oxidizing sterilizing agent and fine bubbles, and supplying the same to a cleaning pipe, The electrolytic reaction stopper is provided with the step of dissolving and cleaning by the washing water and the step of operating the electrolytic water stopper and the actuator by supplying the oxidizing sterilizing agent in the electrolytic water and the fine And a step of oxidizing and desorbing due to the flow friction of the bubbles.

The electrochemical reactions that show the cleaning effect by electrolysis are summarized as follows.

When an electrolysis reaction occurs in water containing chlorine ions, a chlorine gas acts as a powerful oxidizing and disinfecting agent in the anode, and hydrogen gas which is not soluble in the cathode is generated in the cathode.

The gases produced in the anode and cathode through the electrochemical reaction are as follows.

2Cl ^- → Cl ₂ (chlorine gas) + 2e ^- (electrolysis at anode)

H ₂ O + 2e ^- → H ₂ (hydrogen gas) + 2OH ^- (electrolysis at the cathode)

The chlorine gas generated through the electrolysis reaction is dissolved in water because of its high solubility in water and forms an oxidizing bactericide. The chemical reaction formula is as follows.

Cl ₂ (gas) + H ₂ O → HOCl (oxidizing fungicide) + H ⁺ + Cl ^- (oxidation fungicide production reaction)

The oxidizing agent and the fine bubbles generated through the electrolysis reaction penetrate into the gap of the scale layer of the pipe due to the dissolution and oxidization by the turbulent fluid flow, and the flow friction of these minute bubbles and oxidizer And dissolves through reaction with the microbial layer to weaken the bonding force in the pipe, thereby detoxifying and sterilizing contaminants in the pipe and removing it from the pipe.

According to the present invention, it is possible to simplify and lighten the piping cleaning apparatus by supplying the oxidizing agent and the fine bubbles through the electrolytic reaction of the pipeline cleaning water, thereby providing the economical efficiency, the convenience of the cleaning operation, the mobility and the efficiency There is an effect that can be increased.

The effective cleaning effect of the piping is the electrochemical by-product of the electrolysis reaction, which forms chlorine gas and micro-bubbles with oxidative sterilizing power at the anode and cathode, and thus the flow friction of the micro bubbles due to the fluid flow in the pipe water, The cleaning effect of the chlorine gas with the chlorine gas is dissolved, washed, desorbed, and sterilized by the contaminants such as scales deposited on the wall surface of the pipe and the microorganism layer.
