Vertical continuous calcination lime burner

Abstract

The invention discloses a vertical and continuously calcining lime kiln, including a cylindrical kiln body. From the top down, the kiln body is successively provided with an air-lock feeding device, a distributing device, a preheating zone, calcining zone, cooling zone and a continuously discharging device. The air-lock feeding device is located on the top of the kiln body, the distributing device is located on the upper of the inner chamber of the kiln body, the preheating zone is located below the distributing device, the calcining zone is located below the preheating zone, the cooling zone is located below the calcining zone and the continuously discharging device is located below the discharge port but at the cooling zone. The top of the kiln body is equipped with air discharge pipe, heat wind exhaust passage which is devised axially along the kiln body and can extend to the preheating zone is equipped in the inner space of the kiln body, and a plurality of air outlets and inlets are equipped on the copper wall of the heat wind exhaust passage. The invention enables to continuously manufacture, can control the lime in the kiln to drop with a uniform speed, has no sintering phenomenon, can control the lime to fall with constant speed on every level surface in the kiln and completely put an end to undersintering and oversintering.

Description

technical field [0001] The invention relates to a calcined lime kiln. Background technique [0002] Under the general trend of all walks of life requiring energy saving, emission reduction and environmental protection, the current lime kilns (including bedrock coal, flint mixed firing, rotary kiln and imported kiln types) all have defects to varying degrees. For example, the coal-stone mixed firing kiln cannot guarantee that there will be no over-burning and raw-burning, the authenticity rate is very low, and the energy consumption is not environmentally friendly, which has been banned by local governments; the investment in imported kilns is too large, and there are also unreasonable calcination processes. places, higher energy consumption. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vertical continuous calcining lime kiln with reasonable calcining process and continuous calcining. [0004] In order to s...
