PURPOSE: A chlorine inputting machine is provided to supply high quality water by controlling residual chlorine concentration of outflow water near to preset concentration. CONSTITUTION: A chlorine inputting machine comprises a flow detector (210), an inflow water concentration counter (220), an outflow water concentration counter (230), a chlorine input part (240), and a chlorine storage tank (250), and a chlorine input control unit (260). The chlorine input part inputs chlorine by determining flow rate of input chlorine according to residual drug concentration of inflow and outflow water. The chlorine input control unit comprises a data input unit, an outflow drug concentration calculation part, an operation control part, and a chlorine input flow amount calculation part. A data input part is input data from a flow detector, an inflow water concentration counter, an outflow water concentration counter and a chlorine storage tank. The outflow water drug concentration calculation part calculates average outflow chlorine concentration which is accumulated and equalized in predetermined time unit by being inputting residual chlorine concentration data of outflow water from the data input unit. The chlorine input flow amount calculation part calculates flow rate of input chlorine by reflecting average outflow chlorine concentration. The operation outputs operation control signals into the chlorine input part corresponding to the amount of input chlorine. |
