Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to an annealing furnace flue gas treatment device. Background Technology

[0002] In modern industrial production, annealing furnaces are widely used as key equipment for the heat treatment of metallic materials. The annealing process can improve the microstructure and properties of metallic materials, enhance their toughness, and reduce their hardness. However, annealing furnaces generate a large amount of flue gas during operation. This flue gas has a complex composition and poses a significant environmental hazard. The flue gas mainly originates from fuel combustion and the reactions of metals at high temperatures. Fuel combustion produces conventional byproducts such as carbon dioxide and water vapor. Incomplete combustion also produces carbon monoxide and hydrocarbons. Furthermore, sulfur and nitrogen impurities in coal and heavy oil fuels are converted into sulfur dioxide and nitrogen oxides after combustion, all of which contribute to atmospheric pollution. A significant source of pollution is the oxidation of metals at high temperatures, producing metal oxide particles. Some metal impurities also volatilize and enter the flue gas. During the annealing of steel, iron oxide particles are generated, and zinc oxide particles are generated during the annealing of zinc alloys. These flue gases are characterized by high temperatures, complex compositions, and excessive levels of pollutants. Typically, the flue gas emitted from annealing furnaces can reach temperatures of several hundred degrees Celsius, carrying a large amount of recoverable heat energy. Its composition includes not only gaseous pollutants but also various solid particulate matter. If emitted directly without effective treatment, sulfur dioxide and nitrogen oxides can cause acid rain, while particulate matter can lead to smog, harming the ecological environment and human health.

[0003] Traditional flue gas treatment methods have shown many shortcomings. Early direct emission practices have been strictly prohibited by relevant environmental regulations due to the great damage they caused to the environment. However, they are not ideal for treating fine particulate matter and gaseous pollutants. With the continuous improvement of environmental standards and the enhancement of public environmental awareness, this simple treatment method is increasingly unable to meet the modern society's demand for clean air.

[0039] Working principle: When the flue gas enters the interior of the carrying tank 1 from the flue gas inlet 3, the user controls the motor 8 to work by controlling the power controller 19, so that the rotating column 6 at the bottom drives the rotating blade 7 to rotate. The gas is discharged upward through the high-efficiency vortex. The water pump 13 operates to spray water through the cold water pipe 10 from the nozzle 11. The water mixes with the flue gas inside the washing tank 5 to achieve the washing effect. The wastewater after rinsing is discharged through the wastewater outlet 4. This washing treatment can reduce the dust concentration in the exhaust gas, thereby reducing environmental pollution.

[0040] After treatment, the flue gas is transported from the upper transmission pipe 201 to the interior of the insulating barrel 202. After the flue gas enters, the voltage controller 204 controls the activation of the voltage plate 203. The released high voltage breaks down the flue gas, forming positive and negative ions. These ions flow downwards through the electrostatic field 205 and are captured by electrostatic adsorption, thereby achieving the effect of purifying the flue gas. The purified flue gas is discharged into the air from the rear exhaust pipe 206, thus meeting society's demand for clean air.
