项目介绍

Project introduction

酸碱(pH)调节是为满足工艺流程的需要，在电镀工艺中电镀液的pH控制、冶金浮选工艺的矿浆pH控制、化工流程中流程介质母液的pH控制等。在水处理工艺中，被处理水的pH值会影响各种药剂的使用效果，不同种类的废水在完成各种处理后也可能不在允许排放的pH范围内。

In order to meet the needs of technological process, pH control of electroplating solution, pulp pH control of metallurgical flotation process, and pH control of process medium mother liquor in chemical process are used to meet the needs of process flow. In the water treatment process, the pH value of the treated water will affect the use effect of various chemicals, and different kinds of wastewater may not be within the allowable discharge pH range after various treatment.

酸碱自动调节介绍

Introduction of acid base automatic regulation

酸碱pH调节加药装置系统是通过pH在线控制器自动检测被测液体的pH值，并通过设定控制范围转换成电流信号输出到自动加药计量泵，自助加药计量泵(设定接收信号范围及输出频率范围)通过接收到的信号，自动调节计量泵的加药量。

The pH value of the measured liquid is automatically detected by the pH online controller of the acid-base pH adjustment dosing device system, which is converted into current signal by setting the control range and output to the automatic dosing metering pump. The self-service dosing metering pump (setting the receiving signal range and output frequency range) automatically adjusts the dosing amount of the metering pump by receiving the received signal.

酸碱自动控制设置方法

Acid base automatic control setting method

加酸设高报

High acid dosing

如需pH控制在6~9之间，高吸设为9，高断为6，就是pH高于9时，启动加酸泵，达到6了就停止加酸

If the pH is controlled between 6 and 9, the high suction is set to 9, and the high cut-off is 6, that is, when the pH is higher than 9, start the acid feeding pump, and stop adding acid when the pH reaches 6

加碱设低报

Low alarm for alkali dosing

如需pH控制在4~6之间，低吸设为4，低断为6，就是pH低于4时，启动加碱泵，达到6了就停止加碱

If the pH is controlled between 4 and 6, the low suction is set to 4, and the low cut-off is 6, that is, when the pH is lower than 4, start the alkali feeding pump, and stop adding alkali when the pH reaches 6
