Abstract

PROBLEM TO BE SOLVED: To provide a piping cleaning method and a piping cleaning apparatus which achieve effective and high-efficient piping cleaning without exchanging clogged piping, a valve, or the like, reduce pollution loads, and solve the problem of environmental contamination trouble.SOLUTION: In the piping cleaning method and the piping cleaning apparatus, by using a cleaning agent obtained by adding an alkaline aqueous solution 10 to a porous body such as diatomaceous earth as a natural material without adding a chemical to cleaning, the pore structure of the porous body, the properties of the porous body, and the properties of ceramics are exhibited, adhered products (scale) 9 at the inner wall of piping 3 can be efficiently removed with the alkaline aqueous solution only.

Description

The present invention provides a pipe cleaning method and a pipe cleaning device that removes dust, attached products (scale) attached to the inner peripheral surface of a pipe line, and substances attached to a pollutant such as a scale from hot spring water.

The cleaning agent of this invention provides the cleaning agent formed by adding alkaline aqueous solution to the porous body of diatomaceous earth.

The present invention relates to cleaning in which an alkaline aqueous solution is mixed with a porous surface of diatomaceous earth.

The conventional cleaning technique performs cleaning of piping mainly using cleaning balls and sandblast. However, piping and valve replacement have costs, increased time, pointed out pollution loads, and public health problems, and pipe cleaning is carried out regularly due to the occurrence of environmental pollution problems.

In the background of cleaning above, inorganic salts such as calcium, sodium, calcium, magnesium, chlorine, iodine, cobalt, silicic acid, etc. contained in the aqueous solution on the inner wall of the pipe line generate fixed scales in the pipes and related equipment, and ion crystallization As a result, the water flow decreases and the blockage progresses.

As a result, the fixed scale becomes rigid and has increased adhesive strength. It is hard to scrape off with a metal tool because it is very hardened, and it is generally done by chemical injection and chemical injection, but the cost for treating the treated wastewater, for cleaning the chemical Strong acidic chemicals are used to dissolve the cost and curing scale.

Due to the above, chemical reactions occur, pipes, equipment, etc. are dissolved and eroded, so equipment is replaced every time it occurs, increasing costs.

Due to the scale failure of the inner wall of the pipe, there are many issues such as corporate image, complaints, and surrounding environmental problems.

In the above, the present invention aims to solve the problem effectively in claims 1 to 5 by melting and peeling the scale inside the piping system to maintain, prolong life and prevent deterioration of related equipment.

The present invention solves the problem by easily and quickly cleaning the pipe with an alkaline aqueous solution on diatomaceous earth on a hard surface.

Therefore, in this invention, it aims at the provision by containing alkaline aqueous solution ph10 in diatomaceous earth.

The cleaning agent for the inner wall of the pipeline according to the present invention prevents the inner wall of the pipeline from being damaged or deteriorated. The inner wall of the pipe line is washed by mixing an alkaline aqueous solution with diatomaceous earth having a specific surface area characteristic of the porous body.

The present invention relates to a pipe cleaning method and a pipe cleaning device in the range consisting of claims 1 to 5, such as a spray member device, utilization of a nonwoven fabric in a wire shape, or utilization of a water storage tank.

A piping cleaning system which is effective when an alkaline aqueous solution is added to and brought into contact with the step of producing polycrystalline particles of diatomaceous earth particles according to the present invention.
There is no damage to the inner wall of the pipe, the cleaning work can be completed in a short time, and the processing cost is low.

Thus, the work is easy, and by using claims 1 to 5 together, the single and complicated pipe inner wall cleaning is effectively exhibited.

The feature of the present invention is that no addition of chemicals is required, scale adhesion of piping, valves and the like is effectively prevented, and peeling and removal are possible.

The present invention requires little maintenance by adding a cleaning channel and supplying an aqueous solution of solvent.

It was characterized by removing dust and scale attached to the inner peripheral surface of the pipeline by generating diatomaceous earth fine particles into polycrystalline particles and retaining an alkaline aqueous solution.

The diatoms were fired at 1,000 ° C. to produce a specific porous specific surface area.

An alkaline aqueous solution was produced to ph10 and mixed with the above.

The present invention is effective in mixing a detersive alkaline aqueous solution with diatomaceous earth fine particles that sufficiently exhibit the pore structure, porous body characteristics, and ceramic characteristics of the porous body. It is characterized by no restrictions associated with changes each time.

Although there are many piping cleaning systems, there is no industrial waste that can reduce the load of pollutants, reduce costs, and improve easily.

Carbon dioxide is liberated from calcium bicarbonate, a dissolved substance in hot spring water, and scaling occurs from the product of calcium carbonate. To dissolve this scale, the removal of carbon dioxide is maintained with the present invention.
