Description
The present invention relates to a kind of production unit of material of construction, particularly relate to the continous way burning kiln of firing brick-and tile.
Since fritz's Huffman invention in 1856 has the annular kiln of tunnel oven boiler tube,,, still also had problem on structure and operative technique though very much progress is all arranged through the development in 130 years.This annular kiln has 1 successive to grow the kiln pipe of garden annular tunnel type; Can be divided into several firing chambers along whole kiln length of tube; All there is wicket each firing chamber; There are several to add the fuel port of fueling at the kiln top; There is 1 roasting main flue that links to each other with chimney or pump drainage blower fan in vertical diad portion at long garden ring kiln boiler tube; Some branch flues that link to each other with the roasting main flue are communicated with each firing chamber respectively; Branch flue is made of upright branch flue that is shaped shaft and the flat branch flue that is arranged on below the kiln pipe bottom surface; The connection section that joins at branch flue and roasting main flue is provided with air lock.Annular kiln is maintained static by the hack that is contained in of sign indicating number in the running the firing chamber in, relies on fuel to drop into corresponding fuel port in turn, and make its clinkering zone, be each band such as preheating zone, roasting band, insulation belt and cooling zone, mobile continuously along with the progress of roasting.During annular kiln refining brick and tile, maximum shortcoming is that the higher wet basis of water ratio can not kiln-firing, must through dehydrate become butt (water ratio is generally about 7%) after, can kiln-firing.The drying mode of wet basis mainly contains seasoning and artificial seasoning two classes.If adopt original seasoning, not only need the roomy wet basis field of drying in the air, and produce and be subjected to the influence in white rain and season.Artificial seasoning mode originally is to build kiln outside burning kiln separately, the required heat energy of kiln, and mainly from following two aspects, the one, obtain with combustion fuel, the 2nd, recycle and burn till waste heat.Burn till aspect the waste heat in recycling, the roasting cigarette heat that will have water vapor that has is directly sent into kiln; The waste heat that will be incubated cooling zone that has is sent into kiln; What have all sends said two devices into kiln.Adopt kiln to dehydrate the mode of wet basis, not only increased kiln and affiliated facility, increased energy consumption, and the waste heat transport pipe is longer, lost partly heat energy.In addition, if come dry wet basis,, prolonged the time of dehydrating, and effect is also unsatisfactory owing in the process that dehydrates, again moisture content is added to wet basis with the cigarette heat that has water vapor.
In view of the foregoing, purpose of the present invention just is to provide a kind of structure simpler, builds easily, do not need wet basis to dry in the air or kiln, can utilize the waste heat that burns till that reclaims, wet basis is dehydrated processing, make the brick and tile burning kiln of the higher wet basis energy kiln-firing of water ratio.

1. the waste heat main air duct of cooling zone waste heat air channel net is arranged on the vertical diad portion of long garden ring kiln boiler tube, and the waste heat branch air duct is from each firing chamber of connection of above-mentioned main air duct radial.During waste heat air lock in closing whole waste heat branch air ducts, this cooling zone waste heat air channel net promptly becomes 1 closed system that does not communicate with ambient atmosphere, because this waste heat air channel net is arranged on the circular kiln furnace central part,, and improved the basal temperature of kiln pipe so waste heat is difficult for Vent leakage and lost.Waste heat air lock in correspondingly opening the waste heat branch air duct that leads to the firing chamber that is in cooling zone, during with the waste heat air lock that leads in the waste heat branch air duct of firing chamber that the needs that wet basis is housed dehydrate processing, under the suction function of humidity discharging pump drainage blower fan, can be with the waste heat of cooling zone firing chamber, waste heat branch air duct through being communicated with this firing chamber, enter the waste heat main air duct, and then from the waste heat main air duct, through corresponding waste heat branch air duct, enter the firing chamber that wet basis is housed, wet basis is dehydrated processing, then from the humidity discharging mouth, through the humidity discharging branch flue, the humidity discharging air lock, humidity discharging flue collector and discharge kiln.The firing chamber, time, temperature etc. that need dehydrate processing all can control as required, therefore, can effectively utilize the cooling zone waste heat fully, and it is lower to obtain water content, the butt that water ratio is more stable.
2. humidity discharging flue net self-organizing system matches with cooling zone waste heat air channel net, can be as required, and control is left standstill the humidity discharging after the homogenize operation and is dehydrated the humidity discharging of operation.
3. the flat branch flue of roasting branch flue is arranged on more than the kiln bottom surface, and flue length is shorter, is easy to cleaning and maintenance.
4. the wet basis dewatering element is designed to the top flue sheet of humidity discharging flue collector and/or roasting flue collector, can utilize humidity discharging waste heat, roasting cigarette heat, the accumulation of heat of kiln top, kiln to be dissipated in the interior heat radiation of factory building fully, the wet basis of pile on the wet basis dewatering element dehydrated processing.
5. wet basis dehydrates in the treating processes, moisture vapor not in the cooling zone waste heat that is utilized, and employed wet basis dewatering element is equivalent to heat exchanger, and therefore, wet basis does not contact with water vapor, and it is better that it dehydrates effect.
6. this kiln need not used exotic materials and specific installation, and structure is simpler and easy, is easy to build.
The above-mentioned advantage of circular kiln furnace of the present invention, characteristics of the present invention have been constituted, make the Bricks and Tiles Plant need not be provided with not only that the requisite wet basis of original annular kiln dries in the air or kiln, drying plant, and do not need to add in addition the energy and just can provide water content lower, the butt that water ratio is more stable, thereby, can shorten firing time, improve the quality of products, boost productivity, cut down the consumption of energy, reduce cost.In addition, because the all-work from base to the finished product kiln discharge all can be implemented in factory building, therefore, produce the influence of Changes in weather such as not being subjected to white rain and conversion in season, the quality of product and output are all more stable, carry out the exhausting cooling during finished product kiln discharge, the workman does not need in the open and high temperature work down in addition, and labor condition is more superior.
