Abstract
A nozzle for spraying a liquid, comprising a central body which comprises a connecting portion for connecting the nozzle to a supply of liquid, an atomizing portion forming droplets of the liquid, and a liquid supply pipe forwarding liquid to the atomizing portion. The nozzle further comprises a sleeve mounted on the central body, the sleeve comprising a central aperture, which at least partly encloses the atomizing portion of the central body, and a spray angle controlling rim which at least partly encircles the atomizing portion.
Claims20
A nozzle for spraying a liquid, the nozzle comprising:
- a central body which comprises a connecting portion for connecting the nozzle to a supply of liquid, an atomizing portion forming droplets of the liquid, and a liquid supply pipe forwarding liquid from the connecting portion to the atomizing portion and comprising a first opening in the connecting portion and a second opening in the atomizing portion, wherein
- the atomizing portion comprises a deflecting plate extending from a starting portion, at which the deflecting plate is connected to the atomizing portion, to an end portion and arranged in the path of liquid ejected from the second opening to make the liquid flow over a deflection surface of the deflecting plate and form a spray, and wherein
- the nozzle further comprises a sleeve mounted on the central body, the sleeve comprising a central aperture, which at least partly encloses the atomizing portion of the central body, and a spray angle controlling rim which at least partly encircles the atomizing portion in a position located between the second opening and the end portion of the deflecting plate.
A nozzle for spraying a liquid, the nozzle comprising:
- a central body which comprises a connecting portion for connecting the nozzle to a supply of liquid, an atomizing portion forming droplets of the liquid, and a liquid supply pipe forwarding liquid to the atomizing portion, and
- a sleeve mounted on the central body, the sleeve comprising a central aperture, which at least partly encloses the atomizing portion of the central body, and a spray angle controlling rim which at least partly encircles the atomizing portion, wherein
- the liquid supply pipe supplies the liquid within the central aperture of the sleeve.
A mixer for moistening absorbent material for use in removing gaseous pollutants from a hot process gas comprises at least one nozzle for spraying liquid onto absorbent material present inside of the mixer, the nozzle comprising:
- a central body which comprises a connecting portion for connecting the nozzle to a supply of liquid, an atomizing portion forming droplets of the liquid, and a liquid supply pipe forwarding liquid to the atomizing portion, and
- a sleeve mounted on the central body, the sleeve comprising a central aperture, which at least partly encloses the atomizing portion of the central body, and a spray angle controlling rim which at least partly encircles the atomizing portion, wherein
- the liquid supply pipe supplies the liquid within the central aperture of the sleeve.
A method of atomizing a liquid, comprising supplying a liquid to a nozzle comprising:
- a central body which comprises a connecting portion for connecting the nozzle to a supply of liquid, an atomizing portion forming droplets of the liquid, and a liquid supply pipe forwarding liquid to the atomizing portion, and
- a sleeve mounted on the central body, the sleeve comprising a central aperture, which at least partly encloses the atomizing portion of the central body, and a spray angle controlling rim which at least partly encircles the atomizing portion, wherein
- the liquid supply pipe supplies the liquid within the central aperture of the sleeve, and wherein
- the liquid is supplied to the nozzle and is atomized by the nozzle to form an essentially flat spray of liquid droplets.
A method of moistening absorbent material for use in removing gaseous pollutants from a process gas, the method comprises using a mixer having at least one nozzle for spraying liquid onto absorbent material present inside of the mixer, the nozzle comprising:
- a central body which comprises a connecting portion for connecting the nozzle to a supply of liquid, an atomizing portion forming droplets of the liquid, and a liquid supply pipe forwarding liquid to the atomizing portion, and
- a sleeve mounted on the central body, the sleeve comprising a central aperture, which at least partly encloses the atomizing portion of the central body, and a spray angle controlling rim which at least partly encircles the atomizing portion, wherein
- the liquid supply pipe supplies the liquid within the central aperture of the sleeve, and wherein
- the liquid is supplied to the nozzle and is atomized by the nozzle to moisten at least a portion of the absorbent material present inside the mixer.
