Desulfuration and dust removal device based on rotary mist spray and spiral gas-liquid separation principle

Abstract

The invention relates to a desulfuration and dust removal device based on the rotary mist spray and spiral gas-liquid separation principle. The desulfuration and dust removal device comprises a shell, a rotating shaft is arranged on the lower portion of the shell, the lower end of the rotating shaft is connected with a motor located below the shell, an inner cavity is formed in the rotating shaft, and a plurality of liquid outlet holes communicated with the interior of the shell are evenly formed in the side wall of the inner cavity. A gas distributing device is arranged at the bottom of the shell and communicated with a gas inlet pipe located outside the shell. The upper end of the rotating shaft is communicated with a first spray pipe through a rotary water pipe connector. The desulfuration and dust removal device has the advantages that waste gas and a lime solution make sufficient contact through the rotary mist spray method, and thus the waste gas treatment effect is effectively improved; the shell, a first baffle and a second baffle are arranged in a separated mode so that waste gas and a lime solution can be sufficiently separated, and the subsequent treatment effect is ensured; an antibacterial filter layer is arranged and used for removing bacteria and harmful particles in air.

Description

technical field [0001] The invention relates to the technical field of desulfurization and dust removal, in particular to a desulfurization and dust removal device based on the principles of rotary spraying and spiral gas-liquid separation. Background technique [0002] As my country's main primary energy source, coal occupies a large proportion of energy consumption in power plants, boilers and coking industries. Especially this year, with the development of my country's economy, the increase in energy demand has greatly increased the consumption of coal. consume. When coal is burned, sulfur dioxide will be produced. For the coking industry, the carbonization chamber of the coke oven is heated by the gas heating vertical fire channel to provide the heat source. The waste gas generated after the gas heating contains more sulfur dioxide and particulate matter. If these waste gases are discharged directly, this is harmful to the air. The pollution is extremely serious. [000...

AI Technical Summary

Problems solved by technology

However, it is difficult to fully contact and mix the exhaust gas and lime, resulting in the discharge of residual sulfur dioxide gas in the exhaust gas, and the treatment effect is poor; in addition, the discharged gas is doped with more lime solution, resulting in the occurrence of "lime rain" phenomenon
