Description
Technical field
The utility model relates to a kind of Industrial Stoves, especially a kind of crossfire heat-conserving energy-saving multi kiln that is used for piece material such as calcined limestone, dolomite.
Background technology
At present, the stove of generally producing products such as lime, dolomite is built the cross section by laying bricks or stones and is generally circle or rectangle.The core gas permeability of the flow area in round kiln chamber is poor, causes the furnace charge calcining inhomogeneous, and burning quality is low.It is better than length and gas permeability that rectangle is built cross section girth in homalographic by laying bricks or stones.But rectangle is built the straight flange that exists in the cross section by laying bricks or stones and is built by laying bricks or stones and relatively be applicable to lower building by laying bricks or stones or local height.Too high straight flange is built general less stable by laying bricks or stones, even can cause caving in of kiln body.Therefore rectangle is built the cross section by laying bricks or stones and can not be satisfied the requirement that height is built in further raising by laying bricks or stones.
The tradition stove to build aspect ratio by laying bricks or stones less, thisly lower build height by laying bricks or stones and can make the time of contact of burnt gas and raw material shorter.Waste gas by the preheating zone, is unfavorable for the heat of waste gas is fully passed to raw material hurriedly.The waste gas that causes leaving the kiln body also keeps the higher temperature that gets, and waste-gas heat is brought in the atmosphere.Waste a large amount of energy.Therefore, this kiln is unfavorable for further reducing EGT, and heat utilization efficiency is low.
The tradition stove is owing to build aspect ratio less (build by laying bricks or stones highly and be: 17 ~ 20 meters) by laying bricks or stones, generally pending raw material risen to the top and is loaded in the stove that it is heat-treated through skew bridge.This skew bridge promotes charger owing to there is the angle of inclination that forms with ground, and floor space is relatively large.When the stove height was higher, the floor space of this skew bridge was bigger; And when increasing, need to increase steel and improve skew bridge intensity owing to the skew bridge span.So the mode that this skew bridge feeds in raw material can need more steel, take more soil for higher stove height.
So, design a kind of kiln cavity cross-section and can satisfy higher height, good permeability, furnace charge burning quality height, heat utilization efficiency height, the crossfire heat-conserving energy-saving multi kiln that floor space is little of building by laying bricks or stones, be the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of kiln cavity cross-section can satisfy higher height, good permeability, furnace charge burning quality height, heat utilization efficiency height, the crossfire heat-conserving energy-saving multi kiln that floor space is little of building by laying bricks or stones.
The technical scheme in the invention for solving the technical problem is:
A kind of crossfire heat-conserving energy-saving multi kiln, form by pedestal, kiln body, feeding device, burner, drawing mechanism, heat exchanger, end airduct, deduster, suction system and charger, in the housing of kiln body, build layer by laying bricks or stones, the kiln chamber of kiln body is divided into feeding device, heat-accumulating area, preheating zone, calcining zone, cooling zone and discharge zone from top to bottom, and the described layer section configuration of building by laying bricks or stones is for oblate; The aspect ratio prior art of building layer by laying bricks or stones is high 2 to 9 meters; The raised area is called heat-accumulating area between feeding device and preheating zone, described charger is the vertical-lift feeder.
The principle of crossfire accumulation of heat further is interpreted as: though the waste gas in the kiln chamber when the preheating zone with the part heat transferred raw material of preheating zone.But EGT is still very high, has a large amount of heat energy, is worth utilizing.And the raw material of heat-accumulating area has just been entered in the kiln from the external world by feeding device, and this moment, material temperature was near normal temperature.The waste gas and the raw material temperature difference are bigger, can do sufficient exchange heat.In the heat transferred of heat-accumulating area waste gas raw material; Make material temperature near EGT.The heat of raw material storage waste gas, products for further preheating, calcining.Reach crossfire accumulation of heat purpose.
Adopt the oblateness of no straight flange to build the cross section by laying bricks or stones, effectively reduce and build the straight flange wall by laying bricks or stones, improve stability.Can significantly increase and build height by laying bricks or stones.Make the kiln body after increasing the heat-accumulating area height, still can guarantee long service life.
The technical scheme in the invention for solving the technical problem can also be:
Oblate inner chamber described in the utility model is built layer outwards has outstanding arch for periphery rectangle by laying bricks or stones.
The section configuration of the kiln shell of kiln body described in the utility model is oblate.
The sectional area of heat-accumulating area described in the utility model is greater than the sectional area of calcining zone.
The described section configuration of inner chamber of building layer by laying bricks or stones at the middle part or the middle and lower part be that minor face is the rectangle of circular arc, rectangle is built layer and top oblateness by laying bricks or stones and is built by laying bricks or stones between the layer and build layer by laying bricks or stones for rounding off.
The beneficial effects of the utility model are:
The high 2-9 rice of kiln aspect ratio prior art, kiln cavity cross-section good permeability, furnace charge burning quality height, heat utilization efficiency height, floor space are little.
