연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A nozzle device is disclosed that may be used with a fluid-bed dryer apparatus or system. Such a nozzle device includes, in one embodiment, an intake block, an inner tube, an outer tube, a tip and an air cap. The tubes are connected to the intake block to form a passage for liquid and a passage for gas. The tip connects to the inner tube, and the air cap connects to the outer tube, so that at the output the fluid is atomized by the gas. Flow of the liquid and gas through the nozzle is unimpeded, and the nozzle provides substantially constant atomization ...

What is claimed is: 1. A nozzle apparatus comprising: an intake block having a liquid intake opening, a gas intake opening substantially parallel to and offset from said liquid intake opening, and an outlet opening substantially perpendicular to said liquid intake opening, said outlet opening having an outer region extending between an external surface of said block and an internal thread, said outer region being substantially cylindrical and substantially uniform, said outlet opening further having an inner region of a diameter smaller than said outer region that extends between said outer region and an internal thread, said inner region being substantially cylindrical and substantially uniform; a one-piece inner tube having a lumen, a first externally threaded end, a second internally threaded end, a flange adjacent said first end, said first end being threaded into said inner region of said block so that said inner tube flange contacts a portion of said block to form a substantially fluid-tight seal; a one-piece outer tube having a lumen, a proximal threaded end and a distal threaded end, said proximal end being threaded into said outer region of said block so that a portion of said tube contacts a portion of said block to form a substantially fluid-tight seal and at least a portion of said outer tube surrounds at least a portion of said inner tube; a one-piece tip member having a lumen, a threaded end, a narrowing end, and a flange, said tip member lumen having a portion with a substantially constant diameter and a narrowing portion at least partially within said narrowing end, said tip member flange having a plurality of flutes for allowing gas through and changing the motion of said gas, said tip member being threadedly connected to said second end of said inner tube so that said tip member flange contacts a portion of said inner tube to form a substantially fluid-tight seal; and a cap member having a lumen, a rearward end having an opening of said cap member lumen and a forward end having an opening of said cap member lumen that is smaller than said opening of said rearward end, said cap member being threadedly connected to said distal end of said outer tube so that said rearward end contacts a portion of said outer tube to form a substantially fluid-tight seal, wherein said lumens of said inner tube and said tip member form a passage for liquid, said passage having no structure inside it. 2. The apparatus of claim 1, wherein said inner tube and said outer tube form a substantially annular passage for gas. 3. The apparatus of claim 1, wherein said outer tube includes an exterior surface having at least one flat portion for accommodating a turning or gripping tool. 4. The apparatus of claim 1, wherein said inner tube includes an exterior surface having at least one flat portion for accommodating a turning or gripping tool. 5. The apparatus of claim 1, wherein said tip member includes an exterior surface having at least one flat portion for accommodating a turning or gripping tool. 6. The apparatus of claim 1, wherein said threaded ends of said inner tube include standard machine thread. 7. The apparatus of claim 1, wherein said threaded ends of said outer tube include standard machine thread. 8. The apparatus of claim 1, wherein said flange of said one-piece inner tube is substantially between said liquid intake opening and said gas intake opening. 9. The apparatus of claim 1, wherein said block includes a plurality of gas intake openings. 10. A nozzle apparatus consisting essentially of: an intake block having at least one liquid intake opening, at least one gas intake opening, and an outlet opening; an inner tube having a lumen, a first end, a second end and a flange, said first end being connected to said block in said outlet opening so that said inner tube lumen communicates with said liquid intake opening; an outer tube having a lumen, a proximal end and a distal end, said proximal end being connected to said block in said outlet opening and around at least a portion of said inner tube, so that said outer tube lumen communicates with said gas intake opening and so that a substantially annular passage exists between said inner tube and said outer tube; a tip member having a lumen, a connecting end, an outlet end, and a flange, said tip member being connected to said second end of said inner tube so that said tip member lumen communicates with said inner tube lumen, wherein said flange of said tip member forms a substantially fluid-tight seal with said inner tube; and a cap member having a lumen, a rearward end, and a forward end having an opening of said cap member lumen, said cap member being connected to said distal end of said outer tube and over said tip member so that said outlet end is adjacent said opening of said forward end of said cap member, wherein said lumens of said inner tube and said tip member form a passage for liquid, and said substantially annular passage forms a passage for gas. 11. The apparatus of claim 10, wherein at least one of said inner tube, outer tube and tip member has at least one flat portion for accommodating a turning or gripping tool. 12. The apparatus of claim 10, wherein said flange of said inner tube forms a substantially fluid-tight seal with said block. 13. The apparatus of claim 10, wherein said outer tube engages said block to form a substantially fluid-tight seal with said block. 14. The apparatus of claim 10, wherein said connecting end of said tip member has an end surface and said second end of said inner tube is internally threaded and has a seat surface, and said end surface of said tip member and said seat surface of said inner tube abut each other. 15. The apparatus of claim 10, further consisting essentially of a connection portion integral with said block, said connection portion being externally threaded and having a boss. 16. The apparatus of claim 10, wherein said flange of said inner tube is substantially between said liquid intake opening and said gas intake opening. 17. The apparatus of claim 10, wherein said block includes a plurality of gas intake openings.
