Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal coking technology, specifically to a sampling device for detecting coal coking gases. Background Technology
[0002] Coal coking, also known as high-temperature carbonization of coal, is a coal conversion process that uses coal as raw material. Under air-isolated conditions, the coal is heated to approximately 950°C and carbonized to produce coke. Simultaneously, it yields coking gas, coal tar, and recovers other chemical products. Coking gas is an important gaseous fuel in integrated iron and steel enterprises; its main components are hydrogen and methane. Hydrogen for chemical synthesis and methane as a substitute for natural gas can be separated.
[0003] Existing technologies suffer from the problem that particulate matter from coal coking gas can enter the detection device during sampling and detection. This can cause the particulate matter to affect the electrical components within the detection device, ultimately reducing the detection efficiency and accuracy of coal coking gas. To address this issue, we propose a sampling device for coal coking gas detection. Utility Model Content

[0023] Specifically, when sampling coal coking gas using the device, the axial flow fan 16 is powered by the power supply 12.

[0033] Working principle: When sampling coal coking gas using the device, the axial flow fan 16 is powered by the power supply 12. The axial flow fan 16 extracts the coal coking gas. The coal coking gas passes through the particulate matter blocking component 9 and then enters the gas inlet pipe 8 through the gas contact pipe 91. During this process, the coal coking gas drives the rotating blades 95 to rotate, which in turn drives the rotating shaft 96 to rotate. The rotating shaft 96 drives the first rotating bar 97 and the second rotating bar 99 to rotate. The first rotating bar 97 drives the first cleaning bar 98 to rotate. At this time, the second rotating bar 99 drives the rotating circular plate 910 to rotate, and the rotating circular plate 910 drives the second cleaning bar 911 to rotate.
