Problems solved by technology

[0002] At present, there is a common problem in the in vitro separation of mixed bed resins, that is, it is difficult to accurately control the amount of cation / anion resin separated and transported. Once the accuracy of a certain separation and transport is poor, multiple mixed beds sharing a resin in vitro separation system, The difference in resin volume and ratio will increase as the number of separations increases, eventually making each mixed bed unable to operate normally

Embodiment 1

[0019] Embodiment 1, the implementation process of cone bottom separation monitoring

[0020] (1) The cation / anion resin backwashing layering in the cone-bottom separation tower is completed. Before starting the cation resin output operation, start the intelligent monitoring and control device, and the image acquisition unit 1 will wirelessly transmit the picture to the computer intelligent analysis unit 2. The picture Should be as figure 2 shown.

[0021] (2) Set the "reference line" on the computer intelligent analysis unit 2 according to the required ratio of yin and yang resins, such as figure 2 As shown in the "line A" in the figure; at the same time as the delivery of the positive resin, click the start analysis image function key, and the computer intelligent analysis unit 2 starts to dynamically analyze the "line A" and the position of the positive / yin interface in the resin image. During the conveying process of cation resin, the interface continues to decline. Wh...

Embodiment 2

[0022] Embodiment 2, the implementation process of high tower separation monitoring

[0023] (1) The monitoring of the separation process of the high tower requires two image acquisition units 1, the upper-view mirror image acquisition unit 1A, and the lower-view mirror image acquisition unit 1B. After the positive / negative resin backwashing in the high tower is successfully stratified, the intelligent monitoring and control device is turned on, and the image acquisition units 1A and 1B respectively transmit the current mirror image information to the computer intelligent analysis unit 2 interface, and the image is as follows: image 3 shown.

[0024] (2) According to the amount of resin in the high tower and the required ratio of anion and yang resins, set two resin-separated "reference lines A and reference line B" in the upper and lower mirror screens of the computer intelligent analysis unit 2: image 3 Shown in "Line A" and "Line B".

[0025] (3) Click the start image a...

Abstract

The invention discloses a mixed-bed resin in-vitro separating and conveying process intelligent monitoring control device and a mixed-bed resin in-vitro separating and conveying process intelligent monitoring control method. A computer intelligent image analysis technology is applied to mixed-bed resin in-vitro separating monitoring, so that a separated resin conveying end point is reliably judged, and a resin separating and conveying process is relatively rational. On the one hand, the volume and proportion of the mixed-bed resin can be prevented from being mixed; on the other hand, the volume and proportion of the stirred mixed-bed resin can be gradually and automatically adjusted in the resin separating and conveying process until the volume and the proportion are recovered; therefore, the operating effect of a mixing bed can be well maintained, and the automation degree of mixed-bed resin in-vitro separating can be improved; and the working intensity of a worker is reduced.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an intelligent monitoring and control device and a monitoring and control method for the in vitro separation and conveying process of mixed-bed resin used for the fine treatment of condensed water in power plants. Background technique [0002] At present, there is a common problem in the in vitro separation of mixed bed resins, that is, it is difficult to accurately control the amount of cation / anion resin separated and transported. Once the accuracy of a certain separation and transport is poor, multiple mixed beds sharing a resin in vitro separation system, The difference in resin volume and proportion will increase as the number of separations increases, eventually making each mixed bed unable to operate normally. Contents of the invention [0003] The object of the present invention is to provide an intelligent monitoring and control device and monitorin...
