Circulating water dosing device and method

The invention provides a circulating water dosing device and method. Due to the fact that the flowing power of the liquid medicine comes from the height pressure difference, the device does not need adosing pump to convey the liquid medicine, the equipment cost and the operation and maintenance cost of the dosing pump are saved, meanwhile, due to the fact that manual dosing is not adopted, the labor cost is saved, and continuous dosing of the liquid medicine can be achieved, meanwhile, a floating ball liquid level switch is used for keeping the liquid level constant in the chemical dissolvingtank, so that when the height pressure difference is used as chemical liquid flowing power, the chemical liquid flow is kept constant, the uniform water quality of circulating water is guaranteed, the water quality treatment effect is improved, slime deposition and corrosion of a condenser titanium pipe are reduced, and the unit economy is improved. 本发明提供的一种循环水加药装置及方法，由于药液流动动力来自高度压差，装置不需要加药泵输送药液，节约了加药泵的设备成本和运行检修成本，同时，由于不采
