Description
Technical field
Utility model relates to a kind of Industrial Stoves, especially about the improvement to high temperature rotary kiln.
Background technology
Industrial high temperature rotary kiln such as cement rotary kiln adopt coal dust to make fuel usually.It is big that yet coal dust fuel produces the black smoke discharge capacity, is difficult to reach environmental requirement, along with the raising day by day of environmental requirement, adopts small-sized gas generator to make the burning energy, to reduce the black smoke discharging.But small-sized gas burner aerogenesis purity is relatively low, calorific value lower (about 1300kcal/kg), add that the employing normal temperature air is combustion-supporting, cause the rotary kiln firing temperature generally can only reach 1100～1300 ℃, be difficult to satisfy some high temperature (for example high-temperature cement and extraordinary chemical products are burnt till needs about 1450～1500 ℃) and fire requirement.And rotary kiln end is positioned at discharging opening, and nearer apart from combustion zone, and existing rotary kiln not only discharging is taken away a large amount of heat energy, and hyperthermia radiation kiln hood cover in the kiln, and kiln hood high temperature makes and the outer severe operational environment of kiln wastes heat energy simultaneously again.
Chinese patent CN85101687 discloses and a kind of cartridge type calcined by rotary kiln thing has been drained into cooling device by drainage conduit, by exhaust piping heat energy is back to rotary kiln and air preheater by this cooling device again, thereby reaches the used heat utilization.This structure only is that burned material discharge used heat is used, and radiant heat in the kiln is not still made full use of, and cause photothermal wasting, so utilization rate of waste heat is still not high.In addition, external air preheater, occupation of land side not only, but also increased equipment cost.Equally, the disclosed mobile medical garbage combustion device of Chinese patent CN03139618.6, CN03247784.8, the used heat utilization is to make in the flue that air preheater is arranged on rotary kiln is connected, still have the not high deficiency of above-mentioned heat energy utilization rate, and these incinerators only are the low temperature rotary kilns.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, does not increase floor space, and heat energy utilization rate height can significantly improve the high temperature rotary kiln of furnace temperature.
The utility model purpose realizes that main the improvement is to set up air preheater in revolution kiln hood discharging opening kiln hood cover, discharges radiant heat in burned material used heat and the kiln by absorbing, and the heating flame air feed improves heat energy utilization rate and kiln temperature.Specifically, the utility model high temperature rotary kiln comprises rotary kiln body and discharge port end kiln hood cover, it is characterized in that having in the said kiln hood cover hollow air preheater of taking the material passage out of.
Because of the kiln hood cover is the hollow circuit cylinder body structure, for making full use of kiln hood cover space, a kind of better is that air preheater also adopts and the less hollow circular cylinder of kiln hood cover similar shape, and the discharging opening passage is set, for example fan-shaped tapping channel at discharge zone.
In addition, be raising air preheat effect, and make full use of heat energy, be provided with alternate some baffle plates that have in the air preheater, make preheated air in preheater, form tortuous stream, prolong the time of staying in preheater, fully absorb heat.The fin that increases heat exchange area can also be set on the preheater peripheral wall surfaces, and a kind of better is the tubular fin, can effectively increase endotherm area, improves air preheating temperature.
Utility model heats combustion air owing in the rotary kiln head-shield air preheater being set, not only effectively utilized and burnt till radiant heat in kiln discharge material waste heat and the kiln, and can significantly improve the kiln temperature, increase the fin of heat exchange area in the preheater on alternate baffle plate and the peripheral wall surfaces, improved heat exchanger effectiveness especially, can make oxygen supply combustion air temperature be increased to 200～400 ℃ (being equivalent to increase by 200～400 ℃ of kiln temperature), make script relative low-heat value gas generator coal gas fuel can fire high-temperature product by normal temperature.And in the kiln hood cover, air preheater is set, does not increase floor space again, and simple in structure, and kiln hood cover temperature reduces, and has also improved the firing working environment.
Below in conjunction with a concrete embodiment of optimizing, further specify the utility model structure.
Description of drawings
Fig. 1 is a utility model high temperature rotary kiln structural representation.
Fig. 2 is Figure 1A-A sectional structure schematic diagram.
The specific embodiment
Embodiment: referring to accompanying drawing, the utility model high temperature rotary kiln, in rotary kiln 1 discharge end kiln hood cover 2, be provided with less cylinder annular air preheater 3, the bottom discharge zone has the fan-shaped discharging opening of being used to lead to 7, burning spray gun 5 is arranged in the middle circular hole, preheater side face two ends have air inlet 8 respectively, air outlet 9.Alternate flap 6 is arranged in the preheater, make air tortuous mobile, the hollow circular tube fins 4 of numerous interior envelopes are arranged on the peripheral wall surfaces.
