Description

Technical Field

[0001] This utility model relates to the field of gas sampling technology for dry quenching furnaces, and in particular to a device suitable for gas sampling in dry quenching furnaces. Background Technology

[0002] As a key piece of equipment in the steel industry, the sampling and analysis of the gas composition (such as CO, CO2, H2, etc.) inside the dry quenching furnace is a core step in determining its operating status and optimizing production parameters. Because the gas from the dry quenching furnace contains a large amount of dust (such as coke particles and ash), and the sampling environment is often under high temperature and high pressure conditions, existing dry quenching furnace gas sampling devices still face two major problems that urgently need to be solved in practical applications: On the one hand, the replacement of filter elements in existing sampling devices is cumbersome and has low maintenance efficiency. To filter dust in the gas, the sampling device needs to install filter elements in the pipeline, but existing filter elements mostly use flange connections, threaded locking and other fixing methods, which require the use of special tools such as wrenches and screwdrivers to disassemble the connecting parts one by one when replacing them; On the other hand, the existing equipment has insufficient dust removal capabilities, and the filter element is prone to clogging and failure. Dust in the dry quenching furnace gas easily adheres to the surface of the filter element, and long-term accumulation will cause blockage of the filter element pores, reduce gas throughput, and affect sampling accuracy. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a device suitable for gas sampling in dry quenching furnaces. The stainless steel box door can be opened, the push rod can be raised and removed, and then the filter element structure can be disassembled. The filter element and other sealing materials can be replaced without special tools. The filter element body and filter element structure kit can filter impurities from the gas. The gas can be backflushed by an electric ball valve, which is convenient for removing dust adhering to the outside of the filter element.
