Problems solved by technology

[0004] Nowadays, in order to achieve the purpose of water saving in industry, circulating water pursues the operation state of high concentration multiple, but the operation of high concentration multiple will inevitably lead to high alkalinity and hardness of circulating water, which will lead to the deposition of scale-forming substances in water, dissolved oxygen and corrosive ions in water The increase in the number of bacteria and algae and the biological sludge produced by the breeding of bacteria and algae have doubled, causing serious damage to the fouling, corrosion and scaling of the circulating water heat exchange equipment. Safety production brings great hidden dangers
Although there are technologies related to stabilizing the water quality of circulating water in the prior art, the water quality of circulating water is adjusted by adding chemicals or adding purification equipment, etc., but the effect is very small, and it is still impossible to ensure that the circulating water runs at too high a concentration ratio, otherwise There will be certain security risks

Embodiment 1

[0039] The process flow for stabilizing circulating water quality is as follows:

[0040] During normal operation, the circulating water in the circulating water field 101 is sent to the production device 105 through the cooling water supply pipeline after the steam-water heat exchange and cooling from top to bottom through the water drying tower 102. When the water temperature is effectively used in the production device 105 After rising, it will return to the water drying tower 102 for cooling and heat exchange treatment, so as to realize the repeated recycling of circulating water. In order to control the pipes and heat exchange equipment through which the circulating water flows to avoid corrosion and scaling, the circulating water must be treated to stabilize the water quality. When the circulating water needs to be treated with stable water quality, the circulating water delivered from the production device 105 first passes through the dosing system 104, and the dosing s...

Abstract

The invention provides an agent and a method for stabilizing the water quality of circulating water, and the method comprises the following steps: if the water quality of the circulating water needs to be stabilized, the circulating water flowing out of a production device is subjected to agent adding and purification treatment, and then is returned to the production device for reuse; wherein a dosing agent used for dosing treatment is mainly prepared from the following components in parts by mass: 1.5 to 1.8 parts of a scale inhibitor, 2.2 to 2.8 parts of a sterilizing agent and 1.2 to 1.8 parts of a mud stripping agent. The equipment comprises a dosing system, a purification system, a circulating water field and a production device, one end of the dosing system is connected with the purification system, and the other end of the dosing system is connected with the production device. According to the method for stabilizing the water quality of the circulating water, the circulating water is kept in a long-period stable high-concentration-multiple operation state, the impact resistance degree of the circulating water is improved, and system operation is more stable.

Description

[0001] This application is a divisional application with an application date of December 10, 2015, an application number of 201510918297.4, and an invention title of "A Method and Equipment for Stabilizing Circulating Water Quality". technical field [0002] The invention relates to the field of circulating water quality stabilization, in particular to a method and equipment for stabilizing circulating water quality. Background technique [0003] With the development of industrial production, water consumption is increasing, and water supply is insufficient in many areas. Therefore, rational and water saving has become an important issue in the development of industrial production. The industrial application of circulating cooling water has completely solved the problem of water consumption. Problems, achieved the purpose of saving water. [0004] Nowadays, in order to achieve the purpose of water saving in industry, circulating water pursues the operation state of high conc...
