Description
Technical Field
The invention belongs to the technical field of high-temperature detection, and particularly relates to an automatic temperature measuring device and method for a vertical flame path at the top of a coke oven.
Background
The measurement and control of the coke oven temperature are one of key links in the coking industry, and whether the oven temperature is measured in time and accurately directly influences the quality of coke, the service life of the coke oven body and the gas consumption. At present, most coke ovens at home and abroad adopt a manual temperature measurement method, the method is usually repeated once every 4 hours, the temperature measurement is long, the temperature measurement environment is bad, the labor intensity of workers is high, the human error of temperature measurement is high, the temperature cannot be measured in rainy days, the control lag of the oven temperature is serious, the oven temperature fluctuation is high, the stability coefficient is low, and in order to ensure the coke quality, the upper temperature limit control method is usually adopted, and the gas consumption is high. Therefore, manual temperature measurement can not meet the requirements of automatic production, energy conservation and environmental protection of the coke oven.
The automatic temperature measurement control system of the coke oven is used for measuring the temperature of the oven in real time and controlling the consumption of the coal gas in a feedback manner, so that the temperature measurement is accurate and timely, the flow of the coal gas can be regulated in real time, the consumption of the coal gas is reduced, the automatic temperature measurement control system meets the requirements of energy conservation and environmental protection in China, and is a necessary trend of automatic heating control of the coke oven in the future.
At present, two main methods for automatic temperature measurement control of coke ovens are available: the method is that an S-shaped thermocouple is arranged at the top of a coke oven regenerator to measure the temperature, and then the temperature at the top of the regenerator simulates the temperature of a coke oven vertical fire channel through a mathematical model, so as to automatically heat and control the coke oven. For example, chinese patent application No.: 200620072195.1, publication date: the patent literature of 2007, 4 months and 25 days discloses a coke oven fitting flame path temperature measuring device, which is characterized in that a crossing hole channel communicated with a crossing hole is vertically drilled from a furnace top, a thermocouple I is vertically arranged in the crossing hole channel, the depth is directly connected with a first layer of bricks above the crossing hole, a thermocouple II is vertically arranged in a left observation hole, the depth is directly connected with a rising flame path and is positioned at the center line of the crossing hole, a thermocouple III is arranged in a left regenerator top space in a front-back direction, in addition, a calorimeter temperature measuring device I is arranged at the inlet of a brick coal air path on the left side of a basement bottom plate, a circular hole-shaped circulating hole channel communicated with a first layer of refractory bricks on the lower side of the circulating hole is drilled at the lower end of the basement bottom plate, the measured temperature is calculated through a mathematical model, automatic optimized and controlled in series by a computer, the purposes of reducing labor intensity, saving energy, reducing consumption, stabilizing the furnace temperature and improving the quality of coke are achieved.
The other method is to directly measure the temperature in the vertical flame path at the top of the coke oven through an infrared thermometer, and has the advantages of quick, efficient and accurate reaction of the actual temperature in the vertical flame path, and the like, so that the method is widely studied. Methods and devices for infrared thermometry are reported in published chinese patent literature, for example chinese patent application No.: 200410012985.6 and publication No. 2015 1-12 discloses an automatic temperature measuring method and system for coke ovens, wherein the temperature measuring system comprises an annular temperature measuring track, an automatic temperature measuring device with an optical probe, a brush type communication head and an upper computer, wherein the annular temperature measuring track is arranged on the inner side or the outer side of a coke oven face coal charging car track. The temperature measuring method is that an automatic temperature measuring device walks on a temperature measuring track, a temperature measuring probe on the temperature measuring device scans and measures the temperature in a furnace through a standard vertical fire channel temperature measuring hole in the temperature measuring track, the automatic temperature measuring device transmits the acquired temperature data to an upper computer on the ground through a wire communication line through a brush type communication head arranged at one point above the temperature measuring track, and the upper computer analyzes and calculates the temperature of each standard vertical fire channel through the sampling curve data and controls a coke furnace heating system. However, the device is used for mobile temperature measurement, the diameter of the hole cover of the vertical flame path is only about 130mm, the time for mobile temperature measurement is obviously influenced by the moving speed, and the inaccuracy of the positioning of the infrared thermometer in the moving process directly influences the accuracy of temperature measurement. Another example is: the Chinese patent bulletin number is: the patent document of CN2898789Y directly installs an infrared thermometer on an upright fire path, and the high-temperature furnace fire rising in the upright fire path and exceeding 1300 ℃ often causes high-temperature damage of the infrared thermometer although the air stripping and cooling protection of nitrogen exist, the existing practice proves that more than 50% of infrared thermometers are damaged within 6-12 months, and the cost is high.
In summary, it is obvious that the existing automatic temperature measuring device and system for coke ovens have the defects of inaccurate temperature measurement and positioning, easy damage to the infrared temperature measuring instrument, and the like, and limit the wide application of the device and system.

6. An automatic temperature measurement method for a vertical flame path at the top of a coke oven comprises the following steps: the automatic temperature measuring device as claimed in claim 1, comprising the steps of:
step one, lifting a fire hole cover: the movement control mechanism drives the fire hole cover (1) to move upwards along the vertical direction, specifically: the electromagnet sucker (2) is electrified to generate magnetic force to tightly suck the observation hole cover (1); the vertical push rod (4) acts upwards to drive the connecting rod (7) to move upwards, and the fire-viewing hole cover (1) is moved out of the top of the coke oven;
step two, right movement of the fire hole cover: the movement control mechanism drives the fire hole cover (1) to move rightwards along the horizontal direction, specifically: the transverse push rod (15) acts rightwards to drive the connecting rod (7) to move rightwards, and the fire hole cover (1) is moved rightwards to expose the fire hole of the fire standing channel under the non-contact thermometer probe;
step three, temperature measurement: the non-contact type thermometer carries out automatic temperature measurement and outputs the data obtained by temperature measurement to the data processing center;
step four, left movement of the fire hole cover: the movement control mechanism drives the fire hole cover (1) to move leftwards along the horizontal direction, specifically: after the temperature measurement is finished, the transverse push rod (15) moves leftwards, the connecting rod (7) is driven to move leftwards, and the fire hole cover (1) is moved leftwards to be right above the fire hole of the vertical fire channel;
fifth, the fire hole cover is lowered: the movement control mechanism drives the fire hole cover (1) to move downwards along the vertical direction, specifically: the vertical push rod (4) acts downwards to drive the connecting rod (7) to move downwards, the fire hole cover (1) is vertically moved downwards, the fire hole cover is restored to the original position, and the electromagnet sucker (2) is powered off.
