Simple and reliable physical scale inhibition effect detection method and physical scale inhibition method

Abstract

The invention relates to a simple and reliable physical scale inhibition effect detection method and scale inhibition method, aiming at solving the problem that scale inhibition effect can not be detected. The method includes that chloridion concentration of operation water of the equipment and total hardness of operation water of the equipment as well as total hardness of make up water and chloridion concentration of the make up water are measured when wading equipment carries out physical scale inhibition, and the supposed total hardness of operation water of the equipment is calculated according to the following formula, (chloridion concentration of operation water of the equipment / chloridion concentration of make up water)*total hardness of make up water; and the supposed total hardness of operation water of the equipment minuses the actually measured total hardness of operation water of the equipment, and a difference is obtained, and the difference is namely the scale amount separated out by virtue of physical scale inhibition. When the ratio or difference of the supposed total hardness of operation water of the equipment and the measured total hardness of operation water of the equipment is lower than the specified value, pollution discharge frequency or discharge capacity is increased accordingly, and water replenishing frequency or make up water is increased; or scale inhibition level of physical scale inhibition equipment is improved accordingly. The invention can monitor physical scale inhibition control effect in real time, thus avoiding that the equipment is damaged by control failure. The physical scale inhibition method of the invention is simple and feasible and is safe and reliable, not only manpower is saved, but also the equipment is ensured to operate safely.

Description

technical field [0001] The patent of the present invention relates to a physical scale inhibition method, in particular to a simple and reliable physical scale inhibition effect detection method and a physical scale inhibition method. technical background [0002] Since the 1950s, the field of domestic industrial water treatment has begun to test the application of magnetic water devices. The purpose is to magnetize water through a strong magnetic field to prevent scale from adhering to the heat exchange surface. In the past half a century, water treatment equipment using high-voltage electrostatic fields, high-frequency high-voltage electric fields, ion rods, etc., with electromagnetic field methods as the basic method, has been launched one after another, and has been put into operation in various water treatment environments. Because this type of equipment has the characteristics of energy saving, environmental protection, and simple use and management, it is very popular...

Problems solved by technology

[0003] The key to the above problems is that equipment manufacturers that use physical methods to control scale cannot test the actual control ability of their products on scale formation. The situation that cannot be monitored is extremely passive, and this is the case both at home and abroad
