In the process of water supply and drainage treatment, various chemical agents are often added for scale inhibition, sterilization and algae killing, coagulation, and flocculation to achieve the purpose of water purification. These medicaments have solid particles and liquids. During the dosing process, they must be dissolved, diluted, and dosed according to the proportion to achieve the best effect. Therefore, the dosing device is a combination of dosing, stirring, liquid delivery, and automatic control. A set of equipment. It is generally used in circulating water systems that need to add corrosion inhibitors, scale inhibitors, and fungicides to accurately dosing and metering water quality treatment agents. It is widely used in the process circulating cooling water system of air conditioning circulating cooling water, reclaimed water reuse system, wastewater system, steel, petrochemical, thermal power, papermaking, microelectronics, medicine, and other industries.
Working principle:
The dosing device is mainly composed of solution tank, agitator, metering pump, level gauge, electric control cabinet, pipeline, valve, Y-type filter, etc. The dosing device is configured in the mixing box according to the required concentration of the medicine, and after being evenly stirred by the agitator, it is put into the solution box, and the metering pump is used to deliver the prepared solution to the dosing point or the designated system. According to the requirements of different technological processes of users, targeted design and configuration of necessary components can be carried out to realize functions such as automatic remote control.
Features:
1）Customers can choose online conductivity controller, PH value online monitor, redox potential real-time online monitor, automatic sewage valve, pulse flow meter, etc.
2）High degree of automation, uniform and accurate dosing. Through manual stroke adjustment or frequency converter to control the dosing amount, in addition to regularly dosing the medicine into the dissolving barrel, no manual operation is required, which saves a lot of manpower and the dosing amount is more accurate.
3）long lasting. All parts in contact with the chemical liquid are made of PE engineering plastics, which are resistant to strong acids and alkalis, and are resistant to aging. For other special requirements, steel or steel-lined vessels can be used.
4）Users can choose according to their needs: agitator, PLC, thermometer, PH meter, online corrosion rate detector and conductivity online monitor, etc.
5）Specially designed dosing system can be selected for special dangerous areas such as petrochemical industry and marine engineering
