Invention refers to power engineering and can be used for spraying the combustible fluids in boiler furnaces. Atomiser consists of a body with a central fuel passage duct and a periphery spraying agent (steam) duct, and a distributing washer with holes. Atomiser consists of a coupling nut inside which there located is a retainer washer to the edge of which attached is a fuel mixer with spraying agent (steam), which forms with inner surface of coupling nut the continued part of a periphery annular duct with holes meant for the discharge thereof, which is equipped with an inner insert. Outer surface of insert and inner surface of mixer form an inner annular duct, at that the insert has a hole which is meant for fuel discharge and forms the continued part of a central fuel duct; then in the direction of the fuel emulsion movement located is an impingement plate of spray nozzle which is made in the form of a cone; spray nozzle is fixed on a distributing washer whereinto screwed is a fuel emulsion distributor made in the form of a dome with a flat top and forming together with inner surface of coupling nut the annular duct which ends with a circular slot duct meant for discharge of fuel emulsion from atomiser, at that coupling nut and emulsion distributor are made from heat-resistant steel. |

Centrifugal vortex nozzle incorporates a casing with a chamber furnished with an auger furnished with an outer threaded groove. Note that the casing bottom is furnished with a throttling hole and its top is provided with a union with a cylindrical bore. In compliance with this invention, the auger inside features a threaded hole with the thread sense either mating or running opposite to that of the auger outer thread. Note also that the mixing chamber is arranged beneath the auger made up of cylindrical and taper parts. Note also that the aforesaid auger is rigidly linked with the T-shape throttling washer, its cylindrical end face part being provided with three inclined throttling holes with their axes are running tangentially to the chamber inner surface. Note also that the axial cylindrical part rigidly linked to the former is furnished with and axial throttling hole aligned with threaded hole arranged in the auger. Mind that the drag of throttling holes is selected depending upon the properties of liquid being sprayed and the required degree of liquid atomising. Note here that the auger is made in high-strength material, e.g. tungsten, or ruby, or carbide, or sapphire carbides. |

Dust chamber with centrifugal nozzle Invention is related to technology of wet dust collection and may be used in different industries for cleaning of dust-laden gases. Dust chamber contains casing, which is installed at elastic elements, inlet of dust-laden gas flow, fan, suction nozzle of which is connected with casing by means of elastic coupling, outlet nozzle of cleaned gas, water sprayers, which alternate with packet of partitions, mist extractor and device for sludge removal. Packet of partitions is made in the form of at least two partitions, one of which serves as baffle element with through opening and is installed in the packet of the latter. The other partition is made as perforated with perforation ratio of 0.5, at that gap between partitions in packet of partitions amounts to 0.01...0.1 from their height. Mist extractor consists of at least three rows of plates installed in the casing, which have wedge-shaped streamlined form in their section that is perpendicular to the length. Water sprayers are made in the form of centrifugal nozzles, every of which consists of casing with inlet opening, cover, sealing gasket between casing and cover, spring, which is installed between cover and swirler. Swirler is made in the form of cylindrical sleeve turned upside down and installed in respect to casing with annular gap. In swirler there are at least two rows of throttling openings, and in every row there are at least two evenly placed along annular wall of swirler tangential throttling openings. In bottom part of casing orifice insert is installed, which is made in the form of conical orifice with calibrated conical opening that is coaxial to cylindrical surface of swirler and has taper that is reverse to taper of inset conical orifice. |

Screen vertical filter with centrifugal spraying of liquid Invention relates to wet-type dust collection and may be used in chemical, textile, food, light and other industries. The filter has a vertical case, an inlet and outlet branch pipes, a rotor-type filter element made up of two stainless steel screens, a jet and a pan for slime. The filter spraying zone is limited by a coaxial cylinder shell. The centrifugal jets are made up of cases with inlets, covers, sealing gaskets, springs arranged between the covers and swirlers. The swirler is a cylinder cup with its bottom turned upward, installed with a circular gap relative to the case. There are at least two rows of throttling holes made in the swirler, and in each row arranged are, at least, two equidistant tangential throttling holes. There is a jet insert made as a V-ring with a tapered gauged orifice arranged in the case lower part. The proposed invention allows higher efficiency and reliability of dust collection. |
