Technical Field

The utility model relates to a solid waste handles technical field, specifically is a tail gas purification processing apparatus of burning furnace is burnt to solid useless.

Background

The solid waste contains potential energy and can be recycled by incineration. However, since the solid waste has extremely complicated components and contains various pollutants such as heavy metals, waste plastics, waste wood, etc., many chemical reactions occur during incineration, and the generated flue gas contains not only excess air and carbon dioxide but also flue gas pollutants harmful to human bodies and the environment. The existing solid waste treatment process flow is as follows: solid waste enters an incinerator after being subjected to early crushing and the like, smoke generated after the incinerator enters a semi-dry type washing tower, acid gas in the smoke is removed through physical and chemical actions in the semi-dry type washing tower, then the smoke enters a bag type dust collector for dust removal, and finally residual gas is discharged from a chimney.

The bottom gas inlet of the semi-dry type washing tower is a large-diameter connecting pipe, generally about DN750mm, and is used for extending a gas inlet pipe into the tower. For a scrubbing tower with a larger diameter, due to the larger kinetic energy at the gas inlet, when the gas enters the tower body at a high speed, the initial distribution of the gas is not uniform, which can lead to a reduction in the separation efficiency of the tower.
