Embodiment 1

[0039] The present invention is based on the high interception rate of monovalent salt by the DTRO diaphragm, and the characteristics that the conductivity is proportional to the salt content. , the ratio between the first conductivity at the water inlet of the membrane column 11 and the second conductivity at the outlet of the clear liquid will increase. Therefore, the first conductivity at the water inlet of the membrane column 11 and the clear water can be calculated and The ratio between the second conductivities at the outlet of the liquid is used to judge whether the membrane column 11 is lapping.

[0040] Such as figure 1 As shown, the present invention discloses a membrane column running circle monitoring system for DTRO equipment, including: a monitoring component arranged on the DTRO equipment and a control component connected to the monitoring component;

[0041] The monitoring component is used to monitor in real time the first conductivity of the stock solution i...

Embodiment 2

[0045] Embodiment 2 is a preferred embodiment of Embodiment 1. It differs from Embodiment 1 in that it expands the structure and functions of the membrane column lap monitoring system of DTRO equipment:

[0046] Such as figure 2 and image 3 As shown, the DTRO equipment monitored by the membrane column lap monitoring system in this embodiment includes a water inlet pipe 12 , a plurality of water inlet branch pipes, a plurality of membrane column units and a plurality of clear liquid outlet pipes 13 . At least one membrane column 11 is arranged in the membrane column unit. In this embodiment, a plurality of membrane columns 11 are arranged in one membrane column unit, and the membrane column 11 is provided with a water inlet, a clear liquid outlet and a concentrated liquid outlet;

[0047] The water outlet of the water inlet pipe 12 is connected to the water inlet of a plurality of first hoses 17, and the water outlets of the plurality of first hoses 17 are connected to the w...

Abstract

The invention discloses a membrane column out-of-orbit monitoring system and method for DTRO equipment. The system comprises a monitoring assembly arranged on the DTRO equipment and a control assemblyconnected with the monitoring assembly. The monitoring assembly is used for monitoring the first conductivity of a stock solution input into a membrane column and the second conductivity of a clear liquid output by the membrane column in real time, and sending the first conductivity and the second conductivity to the control assembly; and the control assembly is used for receiving the first conductivity and the second conductivity and judging whether the membrane column is out of orbit or not according to the first conductivity and the second conductivity. Whether the DTRO equipment is out oforbit or not can be rapidly monitored, and errors and working intensity of physical senses such as one-listening and two-watching in a traditional troubleshooting method are avoided.

Description

technical field [0001] The invention relates to the field of fault monitoring of DTRO equipment, in particular to a system and method for monitoring membrane column circles of DTRO equipment. Background technique [0002] DTRO (Disk Tube Reverse Osmosis) is a form of reverse osmosis. It is a membrane module specially used to treat high-concentration sewage. Its core technology is a disc tube membrane membrane column. The reverse osmosis membrane and the hydraulic deflector are stacked together, fixed with the center rod and the end plate, and then placed in the pressure sleeve to form a membrane column. The core of the disc-tube membrane system is the disc A membrane column composed of a type diaphragm, a deflector plate, an O-shaped rubber gasket center rod and a pressure-resistant sleeve. The diaphragm and the guide plate are stacked at intervals, and the 0-type rubber gasket is placed in the groove on both sides of the guide plate, threaded together with a central tie ro...
