Desulfuration device based on spiral gas-liquid mixing and rotational flow gas-liquid separating principle

Abstract

A desulfuration device based on the spiral gas-liquid mixing and rotational flow gas-liquid separating principle comprises a shell. A rotating shaft is arranged at the bottom of the shell. The bottom end of the rotating shaft is connected with a motor below the shell. A hollow inner cavity is formed in the rotating shaft. A rotating water pipe connector is arranged at the top end of the rotating shaft and communicated with a first liquid inlet pipe. A plurality of first through holes communicated with the outside of the rotating shaft are formed in the hollow inner cavity. Spiral blades are arranged on the rotating shaft and sleeved with a sleeve. The top end of the sleeve is closed and provided with an air inlet pipe. The bottom end of the sleeve is fixedly connected with the bottom in the shell. The desulfuration device has the advantages that waste gas is driven by the spiral blades to be sufficiently mixed with a lime solution, and the processing effect of waste gas is effectively improved; under the effect of diversion blades, the lime solution contained in waste gas is separated from waste gas, and the 'lime rain' phenomenon is avoided.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to a desulfurization device based on the principles of spiral gas-liquid mixing and cyclone 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. [0003] The existing treatmen...

AI Technical Summary

Problems solved by technology

However, it is difficult to fully contact and mix the exhaust gas and lime solution, 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
