Method and system for accurately obtaining dry quenching coke burn-out rate

Abstract

The invention provides a method and a system for accurately obtaining a dry quenching coke burn-out rate. An interval time period T between two times of adjacent signal communication is obtained through a material level detection device in a dry quenching furnace, coke burn-out amount in the internal time period T and red coke loading amount in the dry quenching furnace in the interval time period T are calculated, and therefore the carbon burn-out rate eta of the dry quenching coke is obtained. The problems that currently, in China, the carbon burn-out rate calculated in a statistics method in most coking plants is not high in accuracy and long in period are solved, so that the carbon burn-out rate can be quickly and accurately obtained, and production can be effectively conducted.

Description

technical field [0001] The invention relates to a method and a system for accurately obtaining the burning loss rate of CDQ coke during the coke production process in the coking industry. Background technique [0002] Coke is an important raw material for blast furnaces. The advanced level of production technology and product quality directly affect the economic and technical indicators and production operations of blast furnaces. Dry coke quenching is a very important link in the coking process. It has incomparable advantages over traditional wet coke quenching in terms of improving coke quality, recycling energy and protecting the environment. In recent years, under the requirements of national industrial policies, domestic CDQ technology has achieved unprecedented development. [0003] CDQ is the use of cold inert gas nitrogen N 2 The process of cooling red coke by exchanging heat with red hot red coke in CDQ furnace. The inert gas that has absorbed the heat of the red...
