Abstract
Description
The present invention relates to a constant chlorine input device capable of remote control, and more specifically, to calculate the amount of chlorine in accordance with the residual chlorine concentration of the raw water, and to drive the metering pump according to the residual chlorine concentration of the output water and the chlorine level of the chlorine tank By controlling the, to reduce the error between the residual chlorine concentration and the set residual chlorine concentration of the water supply to provide a higher quality water supply and chlorine dosing device that is easy to manage according to the re-injection of chlorine.
In general, the constant residual chlorine concentration is maintained at 0.1 ppm to 4 ppm in the faucet. Disposable chlorine in the water supply is disinfected due to a long distance to the water supply line of the water supply facility or a shortage of water supply, which results in a long residence time in the water supply pipe and foreign substances accumulate inside the water supply pipe. There was a problem that the effect is reduced. In order to solve this problem, a high concentration of chlorine is added to the water supply facility to solve the loss of residual chlorine on the average, but this increases the concentration of residual chlorine in the faucet, which increases the disinfection odor and increases the use of water supply. There was a problem that turned off.
Conventionally, in order to solve the above-mentioned problem, chlorine is additionally added to a supply process such as a drainage to secure disinfection of raw water. Conventionally, the introduction of chlorine is made by measuring the residual chlorine concentration of water obtained and then adjusting the residual chlorine concentration set according to the flow rate using a metering pump. However, the conventional chlorine supply device has a problem that it is difficult to control the residual chlorine concentration because the metering pump continues to operate even when the chemical supplied to the metering pump is insufficient or the chlorine effluent concentration is abnormal. In addition, it is difficult to compensate for the residual chlorine concentration difference between the set residual chlorine concentration and the residual chlorine concentration in the output water, because the residual chlorine concentration of the output water which can be changed according to the condition of the sensor, flow meter, and metering pump, etc., which measures the residual chlorine concentration of the incoming water cannot be compensated for. There is this.
The present invention is to solve the above-mentioned conventional problems, and by supplying a higher quality water supply by reducing the error of the residual chlorine concentration and the set residual chlorine concentration of the effluent by adjusting the chlorine input flow rate according to the average residual chlorine concentration of the effluent. It is an object to provide a chlorine dosing device for.
In addition, the present invention is to automatically control the operation of the metering pump in accordance with the average residual chlorine concentration of the effluent and the chlorine level of the chlorine tank to efficiently control the chlorine input to the chlorine input device can be remotely controlled in the water supply line Even if several chlorine injection devices are installed, there is another purpose to effectively manage the concentration by controlling the concentration and the like remotely.
Constant chlorine injection device capable of remote control according to the present invention is the following claims.
According to the constant chlorine input device capable of remote control according to the present invention, the residual chlorine concentration of the effluent is reflected to the input amount of chlorine to adjust the residual chlorine concentration of the effluent to approximate the set concentration. It has the effect of providing water supply.
In addition, there is an effect of reducing the residual chlorine concentration measurement error of the discharged water measured at the point of 20 meters (m) to 30 meters (m) away from the water outlet.
In addition, the amount of chlorine is calculated according to the measured residual chlorine concentration of the effluent, and the control signal is output to the quantitative pump to control the operation of the quantitative pump. Operation of the metering pump is stopped depending on whether the residual chlorine concentration of the water is controlled so that there is no abnormality.
