Description

Technical Field

[0001] The present invention relates to the technical field of industrial furnaces and kilns, and in particular to an exhaust gas treatment device for an industrial furnace and kiln. Background Art

[0002] Industrial furnaces are devices used to heat, melt, or process various substances. They are widely used in many different industries, including metallurgy, chemicals, building materials, and glassmaking. The following are some common types of industrial furnaces: high-temperature furnaces, drying furnaces, combustion furnaces, smelting furnaces, glass melting furnaces, and chemical reaction furnaces. The design and operation of industrial furnaces require consideration of factors such as temperature control, energy efficiency, and exhaust gas treatment to ensure safe and efficient heating, melting, or processing processes.

[0003] Industrial furnace exhaust treatment involves treating the exhaust gases generated by these furnaces to reduce environmental pollution. Common industrial furnace exhaust treatment methods include desulfurization, denitrification, dust removal, VOCs control, flue gas deacidification, energy recovery, and monitoring and control. The appropriate treatment method should be selected based on the specific furnace type and exhaust gas composition, while complying with relevant environmental protection regulations and standards.

[0004] The prior art discloses an industrial furnace exhaust treatment device with application number: CN202223084573.6, comprising an industrial furnace, an exhaust treatment box provided on the right side of the industrial furnace, an exhaust bin provided at the bottom of the industrial furnace, an exhaust pump installed on the top of the exhaust treatment box, exhaust pipes connecting the exhaust bin and the top of the exhaust treatment box inner cavity are installed on both sides of the exhaust pump, and a dust removal filter assembly and a desulfurization and denitrification component are installed in the inner cavity of the exhaust treatment box. The exhaust treatment device of the industrial furnace pumps the exhaust gas into the exhaust treatment box through the exhaust pump, and the dust and impurities remaining therein are filtered by the filter plate, and further purified by the desulfurization and denitrification component provided in the inner cavity thereof, so that the exhaust gas treatment effect is better. When the filter plate needs to be cleaned, the motor can be driven, and the rotation of the screw can push the filter plate out, so that it can be cleaned very conveniently, making the device easy to use and having better subsequent purification effect.

[0005] The above-mentioned exhaust gas is purified by the filter plate and the desulfurization and denitrification components. At the same time, the atomizing nozzle in the inner cavity of the exhaust treatment box sprays alkaline substances through the atomizing nozzle, which causes some solids to remain on the guide plate, making it impossible to collect the solids, and causing a large amount of solid matter to block the atomizing nozzle, thereby making it impossible to spray and desulfurize and denitrify the exhaust gas.

[0006] Therefore, it is necessary to design an industrial furnace exhaust treatment device that is highly practical and can perform desulfurization and denitrification operations on the exhaust gas inside the treatment box multiple times and for a long time. Summary of the Invention
