Internal wireless self-cooled continuous automatic temperature measurement method in coke oven and spectrogram device thereof

Abstract

The invention relates to a novel device aiming at solving the problem of internal temperature measurement of a coke oven. The device comprises the following parts: an intelligent wireless data collection and transmission device, a bionic high-temperature-resistant protection device, a car-mounted computer workstation and a base central computer workstation, wherein the outside of the intelligent wireless data collection and transmission device is provided with the bionic high-temperature-resistant protection device. The intelligent wireless data collection and transmission device carries out mutual contact and information transmission with the car-mounted computer workstation by first-grade wireless communication. The car-mounted computer workstation carries out mutual contact and information transmission with the base central computer workstation by second-grade wireless communication. The device can substitute an original indirect temperature measurement device to carry out wide-angle multi-directional entire direct temperature measurement. A set of temperature measurement devices can be continuously and repeatedly used, has no interchangeable error, can carry out periodical common measurement to tens of thousands of important temperature measurement points of the coke oven, and has accurate measurement data, easy management, easy maintenance and very high direct economic benefits.

Description

Technical field [0001] The invention relates to a method for measuring the temperature inside a coke oven, in particular to a wireless self-cooling and continuous automatic temperature measuring method for the inside of a coke oven and a spectrogram recording device. Background technique [0002] With the development of the world's industrialization, the construction of metallurgical industry furnaces and kilns is rapid and the scale is getting larger and larger. According to incomplete statistics, there are thousands of large metallurgical coke oven kilns in the world, and nearly a thousand in China. The decisive factors for the quality of coke products include: the quality of raw materials (raw media) and the regulation of smelting temperature. In order to achieve a higher coke quality, the main methods used include: changing the proportion of coal types (for coal quality control); effectively improving and controlling the heating state. [0003] In the coking process, because ...

AI Technical Summary

Problems solved by technology

[0005] 1. It is difficult to measure the temperature distribution of the heating cross wall of the carbonization chamber by ordinary temperature measuring instruments;

[0006] 2. Due to the small shape of the opening of the heated vertical fire channel, it is difficult to measure the vertical temperature of the horizontal wall of the heating chamber;

[0007] 3. Due to the high temperature above 1300°C in the furnace, there are a lot of smoke and gases with various components inside and outside the coke oven, including a variety of corrosive gases. These smoke and gases will undergo phase changes under different temperature conditions, and phase changes will form Once the substance is attached to the surface of the thermometer, it will immediately make it unrecognizable, or the thermometer will also be deteriorated and damaged due to high-temperature grilling;

However, this temperature measurement technology has great disadvantages. It needs circulating water to cool the equipment and high-pressure air to purge the probe.

This just causes needing additional multi-layer pipeline and equipment on the coke pusher bar too much, and the weight that increases is too large; , roll tube wheel, etc.) frequent failures and difficult maintenance; circulating water pipes frequently enter and exit the interior of the coke oven, and the difference between high temperature and low temperature is too large, (more than 1300 degrees Celsius inside the furnace, and more than minus 20 degrees Celsius outside the furnace in winter). Expansion and contraction will inevitably lead to serious deformation and frequent damage, so it needs to be replaced regularly. What is more serious is that once water leaks inside the coke oven before the replacement cycle, it will cause serious accidents, so it has not been widely used at home and abroad.
