FIELD: process engineering. ^ SUBSTANCE: invention may be used at enterprises of profound coal conversion into other fuel kinds and may be used in power engineering and transportation. In entrapping coal dust, the latter is pre-neutralised by interaction between sucked flow and grounding electrode. Then, it is subjected to homogenising in contact between coal dust with liquid absorbent inside radial-flow bubble apparatus. Obtained coal-dust suspension is injected into vessel for it to be mixed with other ingredients of liquid boiler oil. Proposed device comprises housing 1 with inlet and outlet branch pipes 2 and 3, suction blower 4 with encased motor 5, radial-flow bubble apparatus 6 with guide grid 7 and collection chamber 8. Said housing additionally accommodates separation chamber 9 and beater 10. Guide grid 7 is arranged inside radial-flow fan. Special openings 14 and gas and fluid passages are made on separation chamber side surface. ^ EFFECT: higher fire and blast safety. ^ 7 cl, 2 dwg |
