Energy-saving environment-friendly baffling vertical lime kiln

Abstract

The invention discloses an energy-saving environment-friendly baffling vertical lime kiln which comprises an air blower, a combustion head, a combustion channel, a heat preservation kiln body, a fixedtoothed plate, a movable toothed plate and a stone guiding plate, wherein a combustion chamber is arranged at the bottom of the heat preservation kiln body, an ash collecting slot is formed in frontof the combustion chamber, an ash discharging hole is formed above the ash collecting slot and is formed between a bearing plate and the heat preservation kiln body, the upper end of the bearing plateis connected with a material guiding inclined hack; a guide block I, a guide block II and a guide block III are arranged inside the heat preservation kiln body to separate the inner part of the heatpreservation kiln body into the S-shaped combination channel; stone materials can slide off in an S shape from top to bottom, the combustion path and the combustion time are prolonged, exhaust gas inthe combustion chamber can conveniently flow from bottom to top in an S shape, and the exhaust gas and stone materials falling off in the combustion channel form convection, so that the stone materialcan be sufficiently combusted into lime; the residual heat in the exhaust gas can be preheated effectively, the heat loss of the exhaust gas discharged from a chimney is reduced, and the stone materials are combusted in the combustion channel in match with the exhaust gas, so that the combustion efficiency and effect of the lime kiln can be guaranteed.

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;
