Online cooling water temperature difference measuring system for wireless blast furnace

Abstract

The invention relates to an online cooling water temperature difference measuring system for a wireless blast furnace. The online cooling water temperature difference measuring system comprises a network server, an industrial control computer, a data converter, a receiving station and an emitting node, wherein the emitting node sends detected water temperature information to the receiving station; the receiving station sends the received temperature information to the industrial computer through the data converter; and the industrial control computer is used for sending the received temperature information to the network server. With the adoption of the online cooling water temperature difference measuring system for the wireless blast furnace, provided by the invention, compared with the wired water temperature measurement system, each temperature measuring point of the online cooling water temperature difference measuring system adopts a digital temperature measurement chip in a wireless digital transmission manner, so that the cable limitation is avoided; and the temperature measurement is accurate and is simple and convenient to transmit. Furthermore, no cable connected with the outside exists, so that the temperature measurement point is easy to seal, and has the relatively great advantages in high-temperature, high-dust-content and high-humidity environments.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of blast furnace water temperature difference, in particular to a wireless on-line measurement system of blast furnace cooling water temperature difference. Background technique [0002] The blast furnace is a closed and huge high-temperature reaction vessel. Changes in erosion or junction thickness in the furnace will be directly and quickly reflected in changes in the heat flow intensity of the cooling water. At the same time, effective cooling and reasonable heat load are also the key to achieving long life and high efficiency of the blast furnace. Therefore, real-time collection of inlet and outlet water temperatures of different cooling water pipes, On-line calculation and monitoring of the heat flow intensity of the cooling system is very important, and it is an important basis for judging the corrosion and junction thickness in the furnace and adjusting the cooling parameters rea...

AI Technical Summary

Problems solved by technology

Due to the special environment of the blast furnace, the measurement system using thermal resistance generally requires wires of different lengths, so that different measurement points will form different errors, and the wires will also affect the temperature measurement due to the influence of the environment.

The measurement system using a digital temperature chip eliminates the influence of the environment on temperature measurement, but the complex environment of the blast furnace makes wiring difficult, and the lines are also vulnerable to high temperature and water vapor erosion, and often cause the entire system to fail due to a single point of failure. paralysis
