Abstract
The utility model relates to a heat recovering device, in particular to a preheating recovering device of a rotary kiln, which solves the problems of serious waste and high-temperature pollution caused by heat radiation of heat on the surface of a kiln body of the existing rotary kiln into the air. The preheating recovering device of the rotary kiln comprises a kiln body, wherein a recovering jacket with a gap between the cylindrical surface of the kiln body and the recovering jacket is sheathed on the cylindrical surface of the kiln body, and in addition, one end of the recovering jacket is provided with a sleeve pipe communicated with a primary fan and a secondary fan. The preheating recovering device of the rotary kiln has the advantages that the structural design is reasonable and reliable, the high-temperature pollution is prevented when the heat utilization rate around the kiln body of the rotary kiln is greatly improved, in addition, the normal production and operation of the rotary kiln is not influenced, the installation and the maintenance are convenient, the structure is simple, and in addition, the cost is low.
Description
Technical field
The utility model relates to heat reclaim unit, is specially a kind of preheating in rotary kiln retracting device.
Background technology
The combustion air of rotary kiln is wind and secondary wind once, and wind and secondary wind once blower fan and overfire air fan are supplied with.A wind feeds burner and participates in burning directly, feeds in the kiln combustion-supporting after the preheating of secondary wind.
To the rotary kiln combustion air, especially secondary wind carries out preheating and feeds in the kiln combustion-supportingly to fuel saving again, and it is very necessary reducing the rotary kiln energy consumption.
General rotary kiln uses producer, and preheating all is to carry out heat exchange by blasting the kiln hood cooler with the red-hot grog that burns till to secondary wind, secondary wind absorbs heat, feed in the kiln combustion-supporting after temperature raises again, grog has also obtained cooling, but the grog that some producer utilizes rotary kiln to burn till wants direct hot charging in electric furnace, does not allow to cool off.Like this, just can not utilize the heat of grog, can only seek other thermal source the preheating of rotary kiln combustion air.And it is well-known, rotary kiln in process of production, rotary kiln surface mean temperature generally all is not less than 150 ℃, especially in the kiln hood section of burning till temperature especially up to more than 300 ℃, a large amount of kiln surface heat energy directly are dispersed in the air, caused very big waste, the high temperature of the kiln body surrounding environment that also causes pollutes.
Summary of the invention
The utility model is dispersed into and causes the serious and high temperature pollution problems of waste in the air in order to solve existing rotary kiln surface heat energy, and a kind of preheating in rotary kiln retracting device is provided.
The utility model is to adopt following technical scheme to realize: the preheating in rotary kiln retracting device, comprise the kiln body, and the kiln body face of cylinder is with and leaves between it recovery chuck in gap, and an end of recovery chuck is provided with the sleeve pipe that is communicated with primary air fan and overfire air fan.During operation, air around the kiln body is heated by its surperficial heat energy, the air that is heated under the effect of primary air fan and overfire air fan is passed into rotary kiln then, has overcome existing rotary kiln surface heat energy and has been dispersed into and causes the serious and high temperature pollution problems of waste in the air.
Reclaim chuck and be made up of the plurality of sections steel part, every section steel part is made up of upper and lower two semi-circular portions, and this kind structural design installs more convenient.
Reclaim chuck and be fixed on the sub-truss, sub-truss is made up of truss and inverted saddle, and this kind structural design is more reliable and more stable.
Reclaim chuck one end and be fixed with the sealing device that seals with the kiln body, and reclaim chuck and be positioned at the uniform air-vent that communicates with sleeve pipe that has of sealing device one end, hot-air in the air-vent enters kiln body inside by sleeve pipe, and hot-air is more even, further guarantees the smooth combustion of flame in the rotary kiln.
Reclaim chuck and sleeve outer wall and be equipped with heat-insulation layer, further improved the utilization rate of heat, prevent the generation that high temperature pollutes simultaneously.
The utility model reasonable in design is reliable, has prevented the high temperature pollution when having improved around the rotary kiln body heat energy utilization rate greatly, and has not influenced the ordinary production operation of rotary kiln, has the advantage that the maintenance of installing is convenient, simple in structure and cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-kiln body, 2-reclaims chuck, 3-primary air fan, 4-overfire air fan, 5-sleeve pipe, 6-steel part, 7-truss, 8-saddle, 9-sealing device, 10-air-vent.
The specific embodiment
The preheating in rotary kiln retracting device comprises kiln body 1, and kiln body 1 face of cylinder is with and leaves between it recovery chuck 2 in gap, and an end of recovery chuck 2 is provided with the sleeve pipe 5 that is communicated with primary air fan 3 and overfire air fan 4.Reclaim chuck 2 and be made up of plurality of sections steel part 6, every section steel part 6 is made up of upper and lower two semi-circular portions; Reclaim chuck 2 and be fixed on the sub-truss, sub-truss is made up of truss 7 and inverted saddle 8; Reclaim chuck 2 one ends and be fixed with the sealing device 9 that seals with kiln body 1, and recovery chuck 2 is positioned at the uniform air-vent 10 that communicates with sleeve pipe 5 that has of sealing device 9 one ends; Reclaim chuck 2 and sleeve pipe 5 outer walls and be equipped with heat-insulation layer.In the specific implementation process, the size of rotary kiln, primary air fan 3 and overfire air fan 4 is looked in gap between recovery chuck 2 and the kiln body 1 and the installation difficulty of rotary kiln body 1 Temperature Distribution situation and recovery chuck is determined, reclaim chuck 2 usefulness bolting and be installed on the sub-truss, the sub-truss bearing is on one grade in rotary kiln and second gear basis.
