Summary of the invention:
The purpose of this utility model provides a kind of rotary type sludge mummification feeder that is used for sludge incinerator, the described this rotary type sludge mummification feeder that is used for sludge incinerator will solve the sludge handling process of prior art, and the drying and incineration link is separated on process and equipment, system complex, reliability is low, heat loss is big, the thermal efficiency is low, equipment is many, occupation of land is big, cost is high, conveying process and the many technical problems of auxiliary device.
This rotary type sludge mummification feeder of sludge incinerator that is used for of the present utility model is by hopper, screw(-type) feeder, the swinging cylindrical shell is configured to propping up, described screw(-type) feeder has a feed end and a discharge end, wherein, described swinging cylindrical shell is arranged in the described support, the front end of swinging cylindrical shell is connected with the discharge end of screw(-type) feeder, described hopper is connected with the feed end of screw(-type) feeder, the front end of swinging cylindrical shell is provided with an exhanst gas outlet, be connected with flue on the described exhanst gas outlet, be provided with a flue gas recirculation blower fan in the flue, be provided with a smoke inlet in the back outlet of swinging cylindrical shell, be arranged at intervals with a plurality of inner fins on the inwall circumference of swinging cylindrical shell, the length direction of any one described inner fin all is parallel to the axial of swinging cylindrical shell, axially be provided with a shaft along it in the swinging cylindrical shell, described shaft is provided with stirring vane, and shaft is connected with driving mechanism with Bearning mechanism.
Further, the back outlet of described swinging cylindrical shell is communicated with the combustion chamber of a sludge incinerator, and an end of described flue is communicated with the combustion chamber of described sludge incinerator.
Further, the axial and horizontal direction of described swinging cylindrical shell is the angle between the 0-10 degree.
Further, described shaft is concentric or eccentric with the swinging cylindrical shell.
Concrete, hopper described in the utility model, screw(-type) feeder, support, flue gas recirculation blower fan and sludge incinerator all adopt known technology of the prior art, about hopper, screw(-type) feeder, support, flue gas recirculation blower fan and sludge incinerator technical scheme in the prior art, those skilled in the art all understands, so do not repeat them here.
Operation principle of the present utility model is as follows: the back outlet of swinging cylindrical shell is communicated with the combustion chamber of sludge incinerator, mud enters the swinging cylindrical shell through hopper and screw(-type) feeder, warm flue gas enters the swinging cylindrical shell in the sludge incinerator upper space, mud and flue gas be direct contact heat-exchanging in the process of reverse movement, mud moisture in moving process is constantly evaporated, and the mud of mummification or half-driedization directly enters sludge incinerator by the back outlet of swinging cylindrical shell.When mud moves forward in the swinging cylindrical shell, under the effect of inner fin, constantly kick up and fall, and contact more fully with hot flue gas after the stirring vane fragmentation of being rotated at a relatively high speed, the particle diameter of mud diminish, can obtain higher heat exchange efficiency and mummification efficient.The low-temperature flue gas that contains organic exhaust gas that the exhanst gas outlet of swinging barrel front end is discharged returns the upper space of incinerator by the flue gas recirculation blower fan, make organic exhaust gas in the flue gas recycled in this regional after-flame, the handling problem that has solved the organic exhaust gas that discharges in the mud drying process.The circulating ratio that can regulate the middle temperature flue gas that enters the swinging cylindrical shell by the flue gas recirculation blower fan is to adapt to the drying and incineration of different solid contents, different calorific value mud.The part lime-ash that can also utilize conveying mechanism that sludge incinerator is discharged is transmitted back in the swinging cylindrical shell and carries out blending with dewatered sludge, to solve the sticking wall problem in the mud drying process.
The utility model and prior art compare, and its effect is actively with tangible.The utility model utilizes the charging gear of swinging cylindrical shell as sludge incinerator, in the swinging cylindrical shell, utilize the hot flue gas in the sludge incinerator that mud is carried out mummification, utilize inner fin and the stirring vane established in the swinging cylindrical shell to improve mummification efficient and effect, realized mummification-burning integral, saved the mud cooling between the drying and incineration, store, the intermediate links such as conveying of conveying and mummification thermal medium, system simplification, take up an area of and reduce, reduced cost of investment, heat loss reduces, saved the Auxiliary Power Unit of intermediate link, improve the operational reliability of system, reduced operating cost; Realize the after-flame of the organic exhaust gas that produces in the drying process, need not to be provided with independent organic waste gas treatment equipment; Circulating ratio by warm flue gas in regulating can adapt to the mummification of different solid contents, different calorific value mud.
