Water pipe chlorine input device and its input method to keep the chlorine concentration in tap water constant

摘要

The present invention is to solve the problem that the residual chlorine concentration is lowered in the water pipe of a certain distance after the chlorine solution is introduced in the water purification plant, so that a certain level of residual chlorine can be maintained in domestic tap water. The water pipe chlorine injecting device of the present invention collects tap water from the water pipe from the water intake valve 501 formed in the water pipe 500 and mixes the chlorine in the chemical tank 400 in the chlorine injecting part 300 to enter the water inlet valve 502 Chlorine dilution is introduced, the residual chlorine concentration of tap water is measured by the concentration sensor 360 formed in the water pipe, and the measured residual chlorine concentration is sent to the remote control unit 310, and the tap water measured by the remote control unit When the residual chlorine concentration of is less than the target concentration of 1ppm, it is configured to mix the chlorine of the chemical tank 400 with the tap water collected by the water intake valve 501 so that the tap water of the water pipe is kept constant at the target concentration of 1ppm.
