Speaking of chemical dosing devices, I wonder if the readers present have a basic understanding of them. A chemical dosing device is a complete set of equipment that integrates multiple functions, including drug delivery, thorough mixing, liquid delivery, and fully automatic control. It is often used in power plant raw water boiler feed water and oil field surface water treatment systems, including various chemical dosing devices and wastewater treatment systems in the petrochemical industry. Next, I will talk to you about chemical dosing devices, their process composition, and some common forms.

It is often used in power plant raw water boiler feed water and oil field surface water treatment systems, including various chemical dosing devices and wastewater treatment systems in the petrochemical industry. Next, I will talk to you about chemical dosing devices, their process composition, and some common forms.
chemical dosing devicesIts main components include a mixing tank, solution tank, level gauge metering pump, electrical control cabinet, valves, check valves, safety valves, filters, pressure gauges, base ladders, etc. These components can be configured according to the specific needs of each user. In the chemical dosing device, different concentrations of chemicals can be configured proportionally in the mixing tank. After being thoroughly mixed by the mixer, it is then transported to the solution tank. Inside, a dosing pump or metering pump is used to transport the prepared solution to the dosing point or the designated system.
chemical dosing devicesCommon forms include chemical water replenishment and boiler water phosphorus salt system. The ammonia addition system can achieve fully automatic control; the preparation of ammonia solution, in addition to manual preparation, can also be automatically controlled. When the solution tank level is lower than the set value, the solution tank inlet valve is automatically opened, and it is automatically closed when it reaches the high liquid level. The control of the amount of ammonia added can be manually controlled or automatically controlled. After PID calculation by the PLC programmable control system, the frequency converter controls the amount of ammonia added by the ammonia metering pump to achieve the purpose of fully automatic chemical addition. For the preparation of phosphate solution, directly add trisodium phosphate to the solution tank dosing point, start the mixer to dissolve, and the control of the amount of phosphate added can also be automatically controlled in addition to manual control. After PID calculation by the PLC programmable control system, the frequency converter controls the amount of the phosphate metering pump to achieve the purpose of automatic chemical addition.
If you add one to the wastewater treatment systemchemical dosing devicesand add emulsifiers, flocculants, coagulants, anions, and cations, etc., the efficiency of wastewater treatment can be improved by using chemical reactions. The existence of the chemical dosing device can better control the concentration of the chemical agent and the amount of chemical added. On the one hand, it can avoid the waste of the chemical agent, and on the other hand, it can also better reduce the cost of manual labor and reduce the overall operating cost. For example, if it is necessary to use pH adjustment or other methods to add chemicals, the existence of the chemical dosing device can better handle this process.
Aboutchemical dosing devicesThe related knowledge is introduced here. I hope this article can help you better understand this equipment.
