Totally-closed mechanical automatic lime cleaning production kiln with air blasting, air induction, dust removal and desulfurization functions

The utility model discloses a totally-closed mechanical automatic lime cleaning production kiln with air blasting, air induction, dust removal and desulfurization functions. A feeding port is formed in the top end of the kiln body; a reinforced concrete structure kiln cover is arranged above the feeding port; a feeding hopper and a distributing device are arranged in the reinforced concrete structure kiln cover; the lower end of the feeding hopper is connected with the distributing device; the reinforced concrete structure kiln cover is located at the top end of the kiln body; the inner diameters of the upper and lower parts of the kiln body reduces toward the directions of the feeding port and a discharging port along the inner wall; two inner walls at the middle section of the kiln body are parallel; a base is arranged at the lower end of the kiln body; a kiln door is formed at one side of the base; and an air blower is arranged at the entrance of the kiln door. The inner container of the kiln body is designed into a smooth fluid arc to satisfy the chemical reaction requirements of calcium carbonate in the kiln and satisfy the top-down physical motion requirements of limestone and finished lime in the kiln; the lime production smoke and the calcium-containing dust are sent into a desulfurization tower by a gravity dust separator through an induced draft fan; and the integral dust removal and desulfurization smoke is discharged with standard level.
