Monitoring system and monitoring method of intermediate cooling system of aluminum oxide decomposing tank

Abstract

The invention relates to a monitoring system of an intermediate cooling system of an aluminum oxide decomposing tank. The monitoring system comprises a PH sensing module, a temperature sensing module,a control module, a display module and a storage module, wherein the PH sensing module is used for collecting PH value data of circulating water from a circulating water inlet and a circulating wateroutlet of a heat exchanger and transmitting the data to the control module; the temperature sensing module is used for collecting temperature data of the circulating water from the circulating waterinlet and the circulating water outlet of the heat exchanger and transmitting the data to the control module; the control module receives the data transmitted by the PH sensing module and the temperature sensing module, carrying out operation comparison on the received data to obtain an analysis result, and outputting a working instruction to the display module according to the analysis result; the display module displays the analysis result of the controller; the storage module is used for storing an operation result of the control module and the received data. Real-time monitoring for the intermediate cooling system is realized; seepage of decomposing liquid and blockage of the heat exchanger can be found in time to avoid accident expansion.

Description

technical field [0001] The invention relates to the technical field of alumina decomposition process monitoring, in particular to a monitoring system for an intermediate cooling system of an alumina decomposition tank and a monitoring method thereof. Background technique [0002] In the production of aluminum industry, it is often necessary to decompose alumina. During the decomposition process of alumina, it is necessary to cool down the decomposition liquid. The intermediate cooling system of the decomposition tank is a very important step in cooling the decomposition liquid. If there is a problem in this step , has a great impact on subsequent production. The existing intermediate cooling system generally uses cold water to exchange heat in the heat exchanger, and transfers the heat in the decomposition liquid to the cold water for cooling. However, in the production process, due to the damage of the equipment, the decomposition liquid is often leaked and cannot be detect...
