1、 Working principle of acid-base dosing device

Due to the requirements of water treatment processes, the pH value of water often needs to be controlled within an irregular range. Manually adding acid or alkali to the water is the most direct and effective method to meet this requirement.

Common acid and alkali neutralizing agents include sulfuric acid, hydrochloric acid, calcium hydroxide, sodium hydroxide, calcium carbonate, and so on.

2、 Product structure of acid-base dosing device

Acid and alkali dosing deviceIt mainly includes the drug solution preparation system, metering and dosing system, safety system, and control system.

Solid drugs are added to the dissolving tank and then mixed with industrial water in proportion to dissolve, and are added to the dosing point by the metering system. Add control

It can be manually controlled or automatically added based on the control signal output by the upper system.

3、 Product features of acid-base dosing device:

Inhalation typeDosing deviceCan be used for mixing, preparing, and adding liquid-liquid, solid-liquid, and gas-liquid drug solutions.

1. Simple structure and stable performance

2. Less land occupation, good economy, easy installation and maintenance

3. The pump is installed by suction and is not easily blocked
