Description

Technical Field

[0001] The utility model belongs to the technical field of spray devices, and in particular relates to a smoke dust reduction spray device. Background Art

[0002] Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex. The gas includes water vapor, SO2, N2, O2, CO, CO2 hydrocarbons and nitrogen oxides, and the smoke includes fuel ash, coal particles, oil droplets and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is a complex pollution of multiple poisons. The harm of smoke to the human body is related to the size of the particles. Most of the dust that causes harm to the human body is less than 10 microns in diameter, especially 1-2.5 microns. The dust is the most harmful.

[0003] Flue gas dust removal is the process of separating the smoke generated by the combustion process of fuel and other substances, as well as the smoke generated by mechanical processes such as crushing, screening and conveying of solid materials, and capturing and recovering these particles from the smoke. In the spray dust collector, water is sprayed into mist through a nozzle. When the dust-containing flue gas passes through the mist space, the dust particles fall down with the droplets due to the collision, interception and condensation between the dust particles and the droplets.

[0004] In various industrial and daily production processes, a large amount of flue gas is generated. There are various spray devices for dust removal of flue gas. The nozzles installed in the existing spray devices are easily clogged by the oily volatile particles contained in the flue dust during long-term use, which requires regular disassembly and maintenance. Since the nozzle structure is installed with screws, it is difficult to disassemble the nozzle for maintenance, which makes the maintenance of the spray device time-consuming and labor-intensive. For this reason, we propose a flue gas dust reduction spray device. Utility Model Content
