Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown, an intelligent control module of a seawater desalination ultrafiltration reverse osmosis device is composed of: a co-processing unit, multiple ultrafiltration intelligent control units, multiple reverse osmosis intelligent control units, multiple dosing intelligent control units, and auxiliary units. The functions of each control unit are described below one by one.

[0039] co-processing unit

[0040] The co-processing unit is the overall coordination unit of the intelligent control system of the whole seawater desalination ultrafiltration reverse osmosis device. Responsible for the collaborative work processing and data storage of all control units in the control module.

[0041] In order to achieve the above functions, the co-processing unit mainly consists of the following parts:

[0042] 1. The man-machine interface is a chann...

Abstract

An intelligent control system for a seawater desalination ultrafiltration reverse osmosis device, including a co-processing unit, an ultrafiltration intelligent control unit, a reverse osmosis intelligent control unit, a dosing intelligent control unit and some auxiliary units; The ultrafiltration intelligent control unit, the reverse osmosis intelligent control unit, and the dosing intelligent control unit work together, and the control water volume allocated to each control unit is based on the water inflow fed back by the ultrafiltration intelligent control unit, each water quality data, and the ultrafiltration produced water. Influence coefficient, comprehensively calculate the dosing demand and send this demand to the dosing intelligent control unit to control the dosing amount. When individual parameters such as turbidity have a greater impact on the dosing amount, you can choose the water quality influence The parameter is turbidity, and the influence coefficient is used as an adjustment parameter. The dosing demand calculated by this method is sent to the dosing control module, so as to further control the dosing volume of the entire system.

Description

technical field [0001] The invention relates to an intelligent control system of a seawater desalination ultrafiltration reverse osmosis device, in particular to the diagnosis and evaluation of the operation performance of the seawater desalination ultrafiltration reverse osmosis device, the related control system and the rapid recovery of each unit. Background technique [0002] In recent years, due to the application of energy recovery, frequency conversion control and other technologies, the energy consumption of seawater desalination ultrafiltration and reverse osmosis projects has been greatly reduced and has been gradually applied and promoted. However, because seawater desalination projects are generally controlled by PLC or DCS, the maintenance workload is very large and very complicated, so the quality requirements for control system maintenance personnel are also very high. At present, seawater desalination projects are only in coastal enterprises that have equipmen...
