[0002] In the UHV DC transmission project, the valve cooling system ensures the safe and stable operation of the converter valve. In the valve cooling system, the spray pump sprays the spray water onto the serpentine heat dissipation coil of the valve internal cooling system to achieve the purpose of heat exchange. In order to meet the requirements of the valve external cooling system for the conductivity of the spray water and the anti-scaling and algae removal characteristics, the chemical addition system needs to treat the spray water. When treating the spray water, it is necessary to add EA798 scale inhibitor, EF711 scale inhibitor and dispersant, and SG2310 bactericide and algaecide to the raw water. The existing addition method is generally that the operation and maintenance personnel directly add EA798 scale inhibitor, EF711 scale inhibitor and dispersant, and SG2310 bactericide and algaecide to the raw water to be treated, which leads to uneven distribution of the liquid medicine, and the liquid medicine reacts slowly with the raw water, affecting the treatment efficiency of the raw water.

The medicine and the raw water can be evenly mixed through the uniform dosing component 6, thereby accelerating the reaction between the medicine and the raw water and improving its treatment efficiency for the raw water. At the same time, it is prevented that the medicine and the solid matter in the raw water stick to each other, which affects the overall ratio of the medicine liquid and causes deviation in the raw water treatment.

At the same time, the solid matter in the raw water is collected by the rotation of the collection filter 705. While the transmission belt 709 rotates, the multiple brush plates 710 on its outside brush the outside of the precipitated solid matter. By stirring the cleaning component 7, the inside of the dosing tank 1 can be self-cleaned.
