Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
Embodiment 1: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, a kind of boiler purification mechanism, comprise deduster 11, airduct 25 and buck return-flow structure 26, deduster 11 right side wall bottom connects boiler 12 left side wall by tracheae 13, in the left end deduster 11 of tracheae 13, blower fan 14A is set, deduster 11 inner vertical evenly arranges cloth bag 23, dust mouth 15 is set bottom deduster 11, deduster 11 top arranges flue 16, airduct 25 comprises: straight tube 19A, straight tube 19B, straight tube 19C, curved cylinder 20A, curved cylinder 20B, flue 16 other end connects straight tube 19A bottom right side wall on antetheca, straight tube 19A top connecting bending cylinder 20A, the curved cylinder 20A other end connects straight tube 19B top, straight tube 19B bottom connecting bending cylinder 20B, curved cylinder 20B other end straight tube 19C, curved cylinder 20B lateral wall right-hand member arranges blower fan 14B, buck return-flow structure 26 comprises lye tank 1, dicyclo spray head 21 and settling tank 9, lye tank 1 inside arranges PH calibrating instrument 22, lye tank 1 right side wall arranges water inlet 4, lye tank 1 left side wall arranges return duct 8, the outer antetheca of lye tank 1 arranges display 2, display 2 top arranges buzzer 3, lye tank 1 top arranges drug filling port 5 near right side wall, lye tank 1 top arranges drain pipe 6 near left side wall, drain pipe 6 is arranged force (forcing) pump 7, drain pipe 6 other end connecting branch 17 right side wall top, arm 17 left side wall arranges five isocons 18, isocon 18 connects the dicyclo spray head 21 being arranged on and arranging in straight tube 19A through straight tube 19A.Connect bottom straight tube 19A and arrange settling tank 9, settling tank 9 right side wall connects return duct 8, and return duct 8 left side arranges screen pack 23, arranges deslagging slurry mouth 10 bottom settling tank 9, and deslagging slurry mouth 10 arranges valve 24.
