Abstract

The invention discloses desulfurization and dust removal equipment and process for lime production. The equipment comprises a desulfurization and dust removal tower and a wastewater concentration tank, a water discharging pipe is arranged on one side of a lower end of the desulfurization and dust removal tower, an inclined guide plate is connected into the lower end of the desulfurization and dustremoval tower, a smoke inlet pipe is connected to one side of the desulfurization and dust removal tower, an overflow port is formed in a side, away from the smoke inlet pipe, of the desulfurizationand dust removal tower, and a partition plate is movably connected into the overflow port through a rotating shaft. The invention provides the lime production desulfurization and dust removal equipment and the desulfurization and dust removal process. The desulfurization and dust removal tower is connected with the wastewater concentration tank; flue gas is guided into the desulfurization and dustremoval tower through an induced draft fan and is spirally guided into an upper end of the desulfurization and dust removal tower through a corrosion-resistant spiral plate, meanwhile, a rotary drumand an arc-shaped plate are arranged, the contact time of the gas and desulfurization liquid is prolonged, the desulfurization effect of the equipment is improved, multiple layers of spraying pipes are vertically arranged in the desulfurization and dust removal tower, and space and energy are saved.

Description

technical field

[0001] The invention relates to the technical field of lime production desulfurization and dust removal, in particular to a lime production desulfurization and dust removal equipment and process. Background technique

[0002] Lime is an air-hardening inorganic gelling material mainly composed of calcium oxide. Lime is made of products with high calcium carbonate content such as limestone, dolomite, chalk, and shells, which are calcined at 900-1100°C. Lime is the earliest cementing material used by humans. Lime is widely used in civil engineering, and it can also be used in medicine in our country.

[0003] The original lime production process is to lay limestone and fuel (wood) in layers, and then ignite and calcinate for a week. In modern times, mechanized and semi-mechanized shaft kilns, rotary kilns, fluidized fluidized furnaces and other equipment are used for production. The calcination time is correspondingly shortened, and it only takes 2 to 4 hour...
