Description
Technical field
The utility model relates to a kind of kiln, especially a kind of energy saving kiln recycling cooling residual heat raising combustion air temperature.
Background technology
Quench zone, slow cooling district and tail cold-zone is subdivided into the salband of existing horizontal kiln (as roller kilns, tunnel cave).Wherein quench zone is first cooling stage after high temperature burns till, and slow cooling district is the second cooling stage, and tail cold-zone is the 3rd cooling stage.At the end of burning till, can cool fast because ceramic product inside exists liquid phase, therefore be referred to as quench zone.Can there is Volume Changes and speed at the crystal formation transfer point of 573 DEG C in the silica in ceramic product, easily produce stress and ftracture, and therefore needing to take slowly the type of cooling indirectly behind quench zone, ftractures to prevent product.Through slow cooled ceramic product temperature about about 400 DEG C, this district can directly to product quenching to kiln discharge temperature, to enhance productivity, this stage claims this to be tail cold-zone or whole cold-zone.The hot blast temperature of tail cold-zone about about 100 DEG C, existing way is generally directly be discharged in air by chimney, not only causes thermal pollution to air, also can increase product specific energy consumption.
Summary of the invention
In order to solve above-mentioned heat waste problem, the utility model provides a kind of and recycles the energy saving kiln that cooling residual heat improves combustion air temperature.
To achieve these goals, the utility model adopts following technical scheme:
This kiln comprises the tail cold-draw fan housing be communicated with tail cold-zone, tail cold-draw heat supervisor, tail cold-draw blower fan, described tail cold-draw fan housing is used for the hot blast in kiln being delivered to tail cold-draw heat supervisor and being connected with tail cold-draw fans entrance, the outlet of tail cold-draw blower fan is for circulation is for airduct, circulation extends to slow cooling district for airduct, inside, slow cooling district be provided with branched equally distributed indirect cooling arm and with the first heat exchange confession airduct and the second heat exchange exhaust column indirectly cool arm and be connected, the first described heat exchange is communicated with for airduct with circulation for airduct, the second described heat exchange exhaust column is connected with heat exchange exhausting supervisor, described heat exchange exhausting supervisor, heat-exchange fan is arranged in Yao Ti slow cooling district, the entrance of heat-exchange fan is heat exchange exhausting supervisor, outlet is provided with the confession airduct leading to combustion fan, what lead to drier supplies airduct and the chimney leading to air.
Preferably, Hand-operated butterfly valve is provided with between described tail cold-draw heat supervisor and heat exchange exhausting supervisor.
Preferably, described tail cold-draw heat supervisor is communicated with by tail cold-draw fan housing with tail cold-zone.
Preferably, described heat exchange supervisor is communicated with by heat exchange draught hood with slow cooling district.
Preferably, described heat-exchange fan is also connected with heat exchange chimney and waste heat interface tube.
Owing to have employed said structure, in a kind of power-saving kiln stove recycling cooling residual heat raising combustion air temperature of the present utility model, the hot-air of tail cold-zone is extracted out through tail cold-draw heat supervisor, again through tail cold-draw blower fan, circulation airduct, heat exchange airduct is delivered in the branched indirect cooling arm of cooling indirectly in kiln, heated by hot-air in kiln (600 DEG C ~ 650 DEG C), can by air heat to more than 180 DEG C, the hot-air high temperature hot gas mixing of releasing again and by heat exchange draught hood, temperature will more than 250 DEG C, this partial air is under the effect of heat-exchange fan, successively by heat exchange airduct, heat exchange is responsible for, be sent to high combustion air exit, prepare for lower chilling heats again.Make heat obtain recycling, decrease the invalid discharge of heat, improve efficiency of energy utilization.
The program has reclaimed the heat of cooling zone to greatest extent, the all hot blasts in tail cold-zone carry out heat exchange by equally distributed indirect cooling arm branched in slow cooling district and slow cooling district after tail cold-zone draught hood is extracted out, then enter after mixing with the high temperature hot gas of directly extracting out through heat exchange draught hood in cold-zone of postponing that to send to burner after quench zone is heated again combustion-supporting; This mode that is multistage, laser heating is not only clean by the heat recovery of cooling zone, and improves combustion air temperature, reaches maximise power-saving.In addition, in slow cooling district all adjacent indirect cooling arm outlet and inlet directions staggered, arrange continuously, wherein one is entered another from one end and brings out, and an adjacent outlet and inlet direction in contrast, extends by that analogy, can reduce the temperature difference in kiln like this.
Enter compared with slow cooling district cools with the direct use room air of routine, using the hot blast of about 100 DEG C, tail cold-zone to be used for the cooling of slow cooling district can be milder, add the indirect type of cooling and indirectly cool arm interlaced arrangement and reduce this district's internal difference in temperature, effectively prevent distortion and cracking defect that ceramic product may occur through slow cooling district, improve product percent of pass.
