Method and system for obtaining coke weight based on dry quenching lifting device

Abstract

The invention discloses a method and a system for obtaining coke weight based on a dry quenching lifting device. An ascent stage and a declining stage of the dry quenching lifting device existing in the coke industry are respectively calculated to obtain a weight G1 of a coke pot for containing coke at the ascent stage and a weight G2 of the coke pot at the declining stage, and a weight G of the coke is obtained through the difference value of the G1 and the G2, namely G=G1-G2. Moreover, the dry quenching lifting device and existing output signals are used, and an accurate weight of a single pot of dry quenching furnace-loading coke is determined through the weight difference of the dry quenching lifting device at the ascent stage and the declining stage. Adding of other large-scale equipment is of no need, an original technological process does not need to be changed, the method is simple, the weight of the obtained coke is accurate, and the statistic analysis of various historical data can be carried out.

Description

technical field [0001] The present invention relates to a method and system for obtaining coke weight in the coking industry, in particular, the present invention relates to a method and system for obtaining coke weight based on a CDQ lifting device. 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 CD...

AI Technical Summary

Problems solved by technology

[0008] (1) The structure of the track weighing method is relatively complicated, the installation requirements are high, and the overall investment is relatively large;

[0009] (2) The belt scale method is not suitable for directly weighing the weight of high-temperature red coke, nor can it realize the weight measurement of the coke before it is loaded into the CDQ furnace, and the measurement result has a large error due to the temperature of the measurement object;

[0010] (3) There is no automated system capable of completing the above-mentioned information recording, historical statistics, and data analysis functions
