A desulfurization and dust removal device based on the principle of rotary spray and spiral gas-liquid separation

Abstract

A desulfurization and dust removal device based on the principle of rotating spray and spiral gas-liquid separation, including a housing, the lower part of the housing is provided with a rotating shaft, the lower end of the rotating shaft is connected to a motor located below the housing, and a hollow inner cavity is provided inside the rotating shaft , the side wall of the hollow inner cavity is evenly opened with a number of liquid outlets connected with the inside of the shell; the bottom of the shell is provided with an air distribution device, and the air distribution device is connected with the intake pipe located outside the shell ; The upper end of the rotating shaft communicates with the first spray pipe through the rotating water pipe joint. The beneficial effect of the present invention is that the waste gas and the lime solution are fully contacted by using the rotary spraying method, which effectively improves the treatment effect of the waste gas; a separation shell, a first baffle and a second baffle are provided to make the waste gas and the lime solution Sufficient separation ensures the subsequent treatment effect; the antibacterial filter layer is used to remove bacteria and harmful particles in the 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
