Abstract
Description
Technical Field
[0001] This invention belongs to the field of coking production technology, specifically relating to an adjustment method for a square-shaped perforated brick in a fixed infrared temperature measuring device. Background Technology
[0002] Currently, fixed infrared thermometers used for measuring the vertical temperature of coke ovens primarily measure the temperature inside the combustion chamber directly through the inspection port. During the measurement process, the heat radiation generated by combustion in the combustion chamber directly bakes the temperature probe, shortening the equipment's lifespan. Simultaneously, dust carried by flue gas leaking from the coke oven and during gas combustion adheres to the surface of the temperature probe, reducing light transmittance and affecting the accuracy of the temperature data. Summary of the Invention
[0003] The purpose of this invention is to provide an adjustment method for a square-shaped brick with a circular hole in a fixed infrared temperature measuring device.
[0004] The technical solution adopted by this invention to solve its technical problem is: an adjustable square-shaped perforated brick in a fixed infrared temperature measuring device, including a solid brick area on the top of a coke oven, wherein the solid brick area on the top of the coke oven is provided with adjustable clay bricks, and the bottom of the clay bricks is provided with a slide rail, which is used to move the clay bricks on the slide rail by a lifting tool; the top of the coke oven is provided with a fire observation hole cover, and a temperature measuring probe is provided at the fire observation hole cover. A vertical fire channel is provided at the bottom of the temperature measuring probe, and a compressed air interface is installed on the side of the vertical fire channel so that compressed air is introduced into the space between the fire observation hole cover and the clay bricks to form a local positive pressure and reduce the adhesion of dust on the surface of the temperature measuring probe.
[0005] Specifically, the provocation tool has a rod with a hook at an acute angle at the bottom and a ring at the top for easy gripping.
[0006] Specifically, the clay bricks are square bricks with round holes.
[0007] A method for adjusting a square-shaped perforated brick in a fixed infrared temperature measurement system includes the following steps:
[0008] 1) When using an infrared fixed temperature probe for temperature measurement, use a prying tool to move the clay brick from the slide to the opposite side so that the clay brick spans and covers the diameter of the fire observation hole. The temperature probe measures the temperature in the combustion chamber through the round hole, reducing the baking of the fixed temperature probe by the heat radiation from the combustion chamber.
[0009] 2) Introduce compressed air into the compressed air interface at a flow rate of 15L / min to create a local positive pressure between the fire-viewing hole cover and the clay brick, thereby reducing the adhesion of dust to the surface of the temperature probe.
[0010] The present invention has the following beneficial effects:
[0011] 1) Set up adjustable square-shaped bricks with round holes and sliding space. When installing the infrared fixed temperature measuring device, cover the lower part of the measuring probe with square-shaped bricks with round holes. During measurement, the bottom fire channel of the combustion chamber is measured through the round holes, which reduces the baking of the fixed temperature measuring probe by the heat radiation of the combustion chamber and extends the service life of the equipment.
[0012] 2) Compressed air is introduced into the space between the fire viewing hole cover and the adjustable square-round hole brick to form a local positive pressure, which reduces the adhesion of dust on the surface of the temperature probe and improves the accuracy of fixed infrared temperature measurement.
[0013] 3) This invention can be extended to the thermal processes and fixed temperature measurement equipment of coke ovens in the same industry, achieving safe, stable and efficient operation, and providing strong technical support for the stable operation of coke ovens in the domestic industry. This invention has high promotion and utilization value. Attached Figure Description

[0019] The invention will now be described in further detail with reference to the accompanying drawings.
[0020] like Figure 1-3 A type of adjustable square-shaped brick with round holes is designed for use in a fixed infrared temperature measuring device. In the solid brick area on the top of a coke oven, at a depth of 800mm from the top, an adjustable clay brick 4 is installed. The brick is square with round holes and a slide rail 3 is provided. If fixed infrared temperature measurement is used, the clay brick 4 is pulled out and made to cross the fire hole channel, forming an isolation chamber between it and the fire hole cover 2. If fixed infrared temperature measurement is not used, the brick is pulled back into the slide rail 3 to ensure normal thermal maintenance and manual temperature measurement needs.
[0021] When using fixed infrared automatic temperature measurement, the temperature at the bottom of the combustion chamber is measured through the clay brick 4.
[0022] Compressed air is introduced into the space between the fire viewing hole cover 2 and the adjustable square-shaped perforated brick to create local positive pressure, thereby reducing the adhesion of dust to the surface of the temperature probe.
[0023] By setting an adjustable clay brick 4 and a sliding space at a position 800mm below the top brick of the coke oven, the clay brick 4 covers the lower part of the measuring probe when installing the infrared fixed temperature measuring device. During measurement, the bottom fire channel of the combustion chamber is measured through the round hole, which reduces the heat radiation of the fire channel combustion from baking the fixed temperature measuring probe and meets the requirements of automatic temperature measurement of the coke oven.
[0024] A method for adjusting a square-shaped perforated brick in fixed infrared temperature measurement involves using a prying tool 7 to move a clay brick 4 from the slide rail 3 to the opposite side, so that the clay brick 4 spans and covers the diameter of the observation hole. The temperature probe 1 measures the temperature inside the combustion chamber through the perforation, reducing the heat radiation from the combustion chamber from baking the fixed temperature probe 1.
[0025] Compressed air is introduced into the compressed air interface 6 at a flow rate of 15L / min to create a local positive pressure between the fire viewing hole cover 2 and the clay brick 4, thereby reducing the adhesion of dust to the surface of the temperature probe 1.
[0026] This invention is not limited to the above-described embodiments. Anyone should know that any structural changes made under the guidance of this invention, and any technical solutions that are the same as or similar to this invention, fall within the protection scope of this invention.
[0027] The technologies, shapes, and structures not described in detail in this invention are all known technologies.
