Title:
NON-POWERED INTER-PIPE MIXING DEVICE, METHOD FOR OPERATING NON-POWERED INTER-PIPE MIXING DEVICE, AND WATER TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/010622
Kind Code:
A1
Abstract:
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.
