Automatic detection and analysis system for temperatures at multiple points of coke oven baking

Abstract

The invention relates to the technical field of coke oven baking process, disclosing an automatic detection and analysis system for temperatures at multiple points of coke oven baking. The automatic detection and analysis system comprises a thermoelectric couple, a compensation lead, a lower computer, a switch board and an upper computer, wherein the upper computer comprises an upper computer work station and a redundancy upper computer work station which are respectively connected with the switch board and respectively comprise a database, a real-time data acquisition module, a data conversion module and a data integrated processing module. According to the automatic detection and analysis system disclosed by the invention, the stability and the data analysis capability of the temperature detection and analysis system in the coke oven baking process can be improved; the process maintenance load, the management cost and the fault rate of equipment are reduced; the coke oven baking quality is improved; the function of full-automatic detection and analysis of temperatures at the multiple points of the coke oven baking is achieved; the actual temperature of a furnace body is ensured to be basically matched with a planned temperature curve; the daily expansion ratio of a coke oven building body is controlled within normal range; the smooth implementation of a coke oven process is ensured; and the quality of the coke oven body is improved.

Description

technical field [0001] The invention relates to the technical field of coke oven oven technology, and is mainly applied to the detection and analysis of the temperature in the coke oven oven. Background technique [0002] In the modern coke oven baking process, thermocouples, acquisition modules and computers are usually used to detect and process the temperature of more than 300 points inside the coke oven to improve the accuracy and continuity of temperature detection, which is very important for mastering the furnace body. Changes in conditions, to ensure the effect of the oven plays an extremely important role. [0003] The oven system in the prior art has the following problems in practical application: [0004] 1. The stability of the existing oven system is poor. Once the acquisition module or computer fails, it will lead to distortion of oven temperature calculation, loss of control of coke oven temperature measurement and loss of oven data. At this time, the oven g...

Problems solved by technology

[0004] 1. The stability of the existing oven system is poor. Once the acquisition module or the computer fails, it will lead to distortion of the oven temperature calculation, loss of control of the coke oven temperature measurement and loss of oven data. At this time, the oven gas supply will be Errors will inevitably lead to uneven temperature rise in each area of ​​the furnace body

[0005] 2. The expansion rate of different positions of the furnace body is not consistent with the design predetermined value, which will damage the tightness of the furnace body. In severe cases, it will cause the masonry to crack each other and damage the furnace protection parts.
