JET APPARATUS Russian patent published in 2004 - IPC

FIELD: mechanical engineering; pumps. SUBSTANCE: invention relates to supersonic jet devices designed for transportation and transfer of different media and their heating. In can be used in different branches of industry. Proposed apparatus contains housing 1, intake channels 2, mixing chamber with contraction section 3 and nozzle 4 installed coaxially to mixing chamber. Nozzle 4 communicates with intake channel 2. Apparatus contains also branch pipe 5 and diffuser 6, cyclone 7 arranged tangentially to housing 1 and provided with branch pipe 5. Diameter of cyclone 7 exceeds diameter of housing 1. Mixing chamber has section 8 of constant or variable cross section which is located after contraction section 3 before diffuser 6. Nozzle 4 installed coaxially with mixing chamber is made in form of de Laval nozzle. Chamber 9 is formed between de Laval nozzle and housing 1. said chamber communicates at one side with cyclone 7 and at other side, with mixing chamber. EFFECT: increased capacity, improved mixing of gas-liquid or liquid compounds and heating of handled medium. 1 dwg
