A heat conducting board (3) is arranged above a combustion kiln chamber (2) and a heat storing fume channel (5) of a kiln body, and net belts (4) which are fixed on driving rollers of a kiln head and a kiln tail are arranged above the heat conducting board; a kiln top is provided with a steam outlet pipeline (1) and an outlet (6) of the heat storing fume channel, the steam outlet pipeline and the outlet of the heat storing fume channel are connected with a wet washing device through a waste gas fume channel (7), and the kiln head is provided with a double-roller material distributing device (8) and an unloading board (10). The kiln has the characteristics of high heat utilization, good effect on energy saving, simple structure, less investment, low cost of sludge disposal, etc.
Description
Technical field: the utility model relates to a kind of kiln body, the continuous drying sludge kiln of particularly a kind of heat accumulating type guipure.
Background technology: municipal sewage treatment is the environmental issue that needs emphasis to solve that the our times various countries are faced, and sewage disposal institute sludge discharged because it contains a large amount of bacteriums, worm's ovum, heavy metal, organic matter etc., becomes big pollution sources in city again.Along with the progress of Chinese Urbanization, the increase of urban population, sewage treatment plant increases, national mud year generation reached more than 9,000,000 tons, and with the speed increase in year 10%.At present, state, inside and outside processing to mud generally adopt to concentrate, digestion, dehydration, mummification, effectively utilize different processing mode or methods of disposal such as (being mainly agricultural), landfill and burning.Wherein, mud carried out drying, sterilization processing after, its as fertilizer sources or auxiliary fuel are used, be to realize sewage sludge harmlessness, minimizing, recycling treatment one approach preferably.
Summary of the invention: technical problem to be solved in the utility model is: a kind of heat energy utilization rate height, equipment investment is little, simple in structure, the Treatment of Sludge expense the is low continuous drying sludge kiln of heat accumulating type guipure are provided.Its technical scheme is: the continuous drying sludge kiln of a kind of heat accumulating type guipure, comprise kiln body and transmission device, it is characterized in that: the burner hearth in the described kiln body and the top of regenerative flue are provided with heat-conducting plate, the top of heat-conducting plate is provided with by the guipure on the Live roller that is fixed on kiln hood and kiln tail, the kiln top is provided with steam (vapor) outlet pipeline and regenerative flue outlet, and outlet links to each other with wet scrubber through the waste gas flue steam (vapor) outlet pipeline with regenerative flue; Kiln hood is provided with pair roller distributing device and blanking plate.Its technique effect is: heat accumulating type guipure continuous drying kiln of the present utility model, owing to be provided with pair roller distributing device and blanking plate at kiln hood, wet mud is on pair roller distributing device and blanking plate enter guipure by the transmission device transmission, at first do heat exchange with smoke convection in the regenerative flue outlet, make the mud preheating, and then make reverse movement with hot gas; Burner hearth through being located at the kiln body and regenerative flue top, the higher heat-conducting plate radiation of thermal conductivity factor, the moisture in the mud is progressively evaporated, and until substantially dry, its moisture that is evaporated is then extracted out by the steam (vapor) outlet pipeline.Therefore, its heat energy utilization rate height, good energy-conserving effect, and it is simple in structure, equipment investment is little, the Treatment of Sludge expense is low.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment:
As shown in Figure 1, heat-conducting plate 3 is stamped in the top of the burner hearth 2 of kiln body and regenerative flue 5.Heat-conducting plate is a carborundum plate, and its thermal conductivity factor height plays the effect of conduction heat.The top of heat-conducting plate is provided with by the guipure 4 on the Live roller that is fixed on kiln hood and kiln tail.Live roller by the motor that is located at kiln tail place by belt and belt pulley transmission.Guipure is made by heat-resistant steel wire, and hole is 3-5mm.The guipure perimeter walls is assembled by the light inorganic material plate, form the heat build-up tunnel with heat-conducting plate, the top is provided with steam (vapor) outlet pipeline 1 and regenerative flue outlet 6, the outlet of steam (vapor) outlet pipeline and regenerative flue links to each other with wet scrubber 12 through waste gas flue 7, and wet scrubber is by the pipeline (see figure 3) that links to each other with exhaust blower 13; Kiln hood is provided with pair roller distributing device 8 and blanking plate 10.
For the draft of steam regulation and flue gas, in steam (vapor) outlet pipeline 1 and regenerative flue outlet 6 and waste gas flue 7 junctions, be respectively equipped with the butterfly valve (not shown).
For heat-insulation and heat-preservation, the body of wall of burner hearth 2 and regenerative flue 5 is built into (see figure 2) by refractory brick, ceramic wool, insulating brick and common brick from inside to outside successively.
Mud is in kiln body inner drying process: wet mud is sent to feeding machine 11 through belt feeding machine 9, be rolled into stick through the pair roller distributing device again, enter on the guipure 4 by the transmission device transmission by blanking plate 10, at first do heat exchange with smoke convection in regenerative flue outlet 6, make the mud preheating, and then make reverse movement with hot gas; Through being located at kiln body burner hearth and regenerative flue top, higher heat-conducting plate 3 radiation of thermal conductivity factor, the moisture in the mud is progressively evaporated, and until substantially dry, discharges to the kiln tail, can be used as auxiliary fuel, also can be used as agricultural fertilizer; Its moisture that is evaporated then is evacuated to waste gas flue 7 by steam (vapor) outlet pipeline 1, after wet scrubber is handled, waste gas is discharged from chimney again.
