Problems solved by technology

However, there are currently a large number of unit tanks in caustic soda production plants. There are more than 1,600 sets of unit tanks in a 250,000-ton/year caustic soda plant. At present, there are several methods for collecting the voltage of the electrolyzer. The traditional method is to pass the voltage manually. The meter measures the voltage of the electrolytic cell. The above collection method has the following disadvantages: 1. Real-time measurement cannot be realized, and it is often collected once a day or several days. During the production process, problems in the production of a single electrolytic cell cannot be found in real time
2. The workload is heavy and the working environment is harsh. It usually takes several hours to measure the voltage data of all the electrolytic cells. At the same time, the operating environment of the electrolytic cell is hig

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] An ionic membrane electrolyzer management and background data processing system, including electrolyzer groups, connecting wires, voltage fast switching devices, PLC, switch electrolyzer service manager, user terminal, DCS, PHD real-time database;

[0024] There are N groups of electrolytic cell groups, and each group of electrolytic cell groups includes n unit electrolytic cells, and each unit cell is connected to the voltage fast switching device through a separate connection line, and connected to the PLC through a data line. In the present invention, due to the large number of voltage measurement points in the unit tank, often thousands, and the limitation of the number of PLC signal inputs, the method of directly connecting the measurement signal of each unit tank to the PLC cannot be realized. The present invention creatively contro...

Abstract

The invention discloses an ionic exchange membrane cell management and background data processing system which comprises an electrolytic cell unit, a voltage quick switch device, a PLC, an exchanger and an electrolytic cell service manager. Each of the unit cells is connected to the PLC through the voltage quick switch device; the PLC controls the voltage quick switch device, so that multiple measuring signals share one PLC analog input and the cell voltage data of each unit cell are uploaded to a real-time database system of the electrolytic cell service manager. By way of measuring the voltage of the unit cell by controlling the voltage quick switch device through the PLC, the quantity of PLC is greatly reduced, the investment is reduced and the data communication pressure is alleviated, thereby providing a storage platform for big data analysis of users. The real-time operating data of the cell is conveniently developed, and the actual operating condition of the cell is analyzed by historical statistics.

Description

technical field [0001] The invention belongs to the technical field of chlor-alkali equipment, in particular to an ion-exchange membrane electrolyzer management and background data processing system. Background technique [0002] Chlor-alkali industry refers to the industrial production of caustic soda, chlorine and hydrogen by electrolysis of saturated NaCl solution. It is one of the important basic chemical industries. The electrolysis is carried out in a vertical diaphragm electrolyzer, which divides the electrolyzer into an anode chamber and a cathode chamber. When the power is turned on, under the action of the electric field, the negatively charged Cl - and OH - moving towards the anode, the positively charged Na + and H + Moving to the cathode, under these conditions, the following reaction occurs on the electrode: [0003] Anode 2Cl - -2e=Cl 2 ↑ [0004] At cathode 2H + +2e=H 2 ↑ [0005] That is, Cl is released in the anode chamber 2 , the cathode compar...
