NON POWERED INTER PIPE MIXING DEVICE METHOD FOR OPERATING NON POWERED INTER PIPE MIXING DEVICE AND WATER TREATMENT SYSTEM

摘要

Disclosed are: a non powered intra pipe mixing device facilitating the attachment/detachment of a chemical injection unit assembly enabling the inspection of the chemical injection unit assembly in a state in which a water supply is not cutoff minimizing by means of the chemical injection unit assembly the influence of a flow rate on a material to be mixed which flows into the non powered intra pipe mixing device capable of measuring the mixing ratio of a chemical to the material to be mixed which is discharged from the non powered intra pipe mixing device by using a sample collection unit assembly and capable of effectively removing by using an open hole for cleaning foreign matter to be precipitated inside the non powered intra pipe mixing device; and a method for operating the non powered intra pipe mixing device. The non powered intra pipe mixing device comprises an inflow pipe a mixing pipe a discharge pipe a chemical injection unit assembly and a cleaning cover. The method for operating a non powered intra pipe mixing device as a method for injecting a chemical into the inflow pipe or collecting a liquid sample to be discharged from the discharge pipe by using the non powered intra pipe mixing device set forth in claim 7 comprises: a chemical injection control step of injecting a chemical into the non powered intra pipe mixing device by using the chemical injection unit assembly; and a sample collection control step of collecting by using the sample collection unit assembly a part of a liquid to be discharged from the non powered intra pipe mixing device.
