Abstract

The invention relates to a metering and on-line control method of a cement production water footprint and belongs to the field of water resource management of cement production. The metering and on-line control method is characterized in that the method is accomplished in a cement production water footprint metering and on-line control system controlled by a central control computer, and comprises the steps of measuring fresh water supplement quantity, circulating water quantity, discharged water quantity and effective water utilization quantity in real time under the control of the central control computer, accordingly working out comprehensive water consumption, water loss, and a circulating rate, an effective utilization rate and a loss rate of a water resource, sequentially judging whether the circulating rate of the water resource reaches a standard, whether the loss rate and the circulating rate of the water resource meet a set threshold simultaneously, and whether the effective utilization rate of the water resource is higher than 50%, and adopting failure removal measures corresponding to different stages till meeting a set object. The method facilitates boosting the green progress of the cement industry under the condition of saving the water resource, and facilitates saving the initial investment and operating cost.

Description

technical field [0001] The invention belongs to the field of water resource management of cement production, and in particular relates to a method for measuring and on-line control of the water footprint of cement production. Background technique [0002] The invention discloses a measurement and on-line control system for the water footprint of cement production, which belongs to the field of water resources management of cement production. [0003] "Water footprint" is the amount of water required by all products and services consumed by a country, a region or a person within a certain period of time. my country's water environment is facing various pressures such as water pollution, water resource shortage, and flood disasters. For a long time, my country's economic growth mode has been extensive, and enterprises have only pursued economic benefits, ignoring environmental and ecological benefits. In industrial development, water consumption is large and utilization rate...
