Detailed Explanation of the Automatic Chemical Dosing Device for Acid Fog Towers – Baoheng Pump Industry

Thread Content

The acid-base adjustment by the automatic dosing device in acid mist towers is a common process in industrial production; however, it is usually carried out manually, which prevents accurate dosing and results in large fluctuations in the pH value of the treated water. This device is equipped with advanced online PH detection and control instruments that regulate the dosing of acid and alkali pumps in a proportional manner. The concentration of the acids and alkalis used for dosing can be set, thereby keeping the PH value of the liquid within a specific range. It also features functions for controlling the liquid level and the mixer, allowing for precise adjustment of the PH value. The automatic dosing system for acid mist towers serves to regulate the pH value and alkalinity: it detects the pH level of the water in the wastewater tank using an online pH monitoring probe, and displays the pH reading on the instruments located in the control cabinet (electrical box). The pH value is automatically adjusted by setting a range for it; when the pH value is below 6, the metering pump is activated to add alkali, and it stops working once the pH value reaches 7.5. The range can be adjusted. When the pH value is above 9, the metering pump for adding acid automatically turns on; it shuts off when the pH value reaches 7.5. Product description of the automatic dosing unit for acid mist towers: Tank capacity: 40L, 300L, 1000L, 8000L, etc. Applicable metering pump capacities: from 0.02L/H to 1200L/H. Material: imported polyethylene plastic raw material. Common colors: blue, white, black, orange, yellow. The integrated dosing unit consists of three main parts: 1. Mixer ; 2. Chemical dosing tank ; 3. Metering devices and dosing equipment. Working principle 1: Mixer: It consists of a mixing blade and a driving mechanism; its function is to mix the solute to be added with water (the solvent) in a certain ratio to ensure thorough mixing. 2. Chemical dosing tank: Used to store the mixed solution for use by the dosing equipment. 3. Metering devices and dosing equipment: Solution dosing is carried out using metering pumps; the metering performance is ensured by using imported PE materials and through one-time rotational molding. It features hygiene and portability, as well as strength and corrosion resistance, shock and impact resistance, and UV protection that prevents aging. Applications: 1. Used in water treatment as coagulants, filter aids, disinfectants, acids, and bases. 2. Add scale inhibitors to cooling water and circulating water. 3. Addition of acids, alkalis, and other solutions in the chemical, papermaking, and printing industries.

A precision metering pump + online pH monitor can be used to adjust the pH of the liquid in real time. 31% hydrochloric acid is to be used, with a flow rate of around 150 L/h – is this feasible?
