An energy-saving and environment-friendly baffled vertical lime kiln

Abstract

The invention discloses an energy-saving and environment-friendly baffle vertical lime kiln, which comprises a blower, a combustion head, a combustion channel, a heat preservation furnace body, a fixed tooth plate, a movable tooth plate and a guide stone plate. The front of the combustion chamber is provided with an ash collection tank, and the top of the ash collection tank is provided with an ash discharge port. The ash discharge port is set between the bearing plate and the heat preservation furnace body. The first guide block, the second guide block and the third guide block divide the interior of the heat preservation furnace body into an S-shaped combustion channel; it is convenient for the stone to slide down in an S-shape from top to bottom, prolonging its firing path and firing time, and also facilitating the combustion of smoke in the combustion chamber. The gas flows in an S shape from bottom to top, and forms convection with the falling stones in the combustion channel, which promotes the adequacy of burning the stones into lime; effectively absorbs the waste heat in the flue gas for preheating, and reduces the risk of flue gas discharged from the chimney. Heat loss, combined with the firing of stone materials in the combustion channel, ensures the efficiency and effect of lime kiln firing.

Description

technical field [0001] The invention relates to the technical field of lime kiln equipment, in particular to an energy-saving and environment-friendly baffled vertical lime kiln. Background technique [0002] Lime kiln is a kind of lime production equipment, which mainly includes base and furnace body. The inner cavity of furnace body is usually called furnace, and raw materials are calcined in the furnace. [0003] In the prior art, a common kiln generally includes a furnace body with an insulating layer, a top feed inlet, an ash discharge port and a smoke outlet. Such a design is relatively simple, but the disadvantage is that the existing common kiln needs to Introducing air to ensure combustion generally requires high-temperature air to ensure combustion efficiency without affecting the temperature in the furnace. The production of ordinary high-temperature air also consumes a lot of energy, which will increase production. In the process of rapid combustion production, ...

Problems solved by technology

[0003] In the prior art, ordinary kilns generally include a furnace body with an insulating layer, top feed inlet, ash discharge port and smoke outlet. Such a design is relatively simple, but the disadvantage is that the existing ordinary kiln needs to In order to ensure combustion, high-temperature air generally needs to be introduced to ensure combustion efficiency, and at the same time, it will not affect the temperature in the furnace. The production of ordinary high-temperature air also requires a lot of energy, which will increase production. In the process of rapid combustion production, it is not possible to quickly calcine lime materials to prepare burnt quicklime, because of the low yield of burnt quicklime, in order to reduce costs, it will not add combustion materials intermittently

Furthermore, the lime kiln in the prior art, on the one hand, cannot achieve energy saving and environmental protection;
