A cyclone dust collecting apparatus for a vacuum cleaner comprises a cyclone body having a first cyclone and a second cyclone, an air inlet and an air outlet connected to the cyclone body, and a dust receptacle connected to the cyclone body. The dust receptacle includes a receptacle body and a partition member. The partition member is mounted on an inner circumference of the dust receptacle, and divides the inside of the dust receptacle into an upper and a lower dust collecting chambers. The lower dust collecting chamber is formed larger than the upper dust collecting chamber.
摘要:
A cyclone arrangement for separating particles or droplets from a fluid stream, including at least two cyclones (1, 2, 3; 21, 22, 23), which have a tangential intake opening (4, 5, 6; 24, 25) for the fluid stream and set the fluid stream into rotation so that due to the resulting centrifugal force, particles or droplets to be separated from the fluid stream may be discharged from the cyclone separator through discharge openings (10, 11, 12). A plurality of cyclones are connected in parallel, and the intake openings (4, 5, 6) of the cyclones are closed or opened by a common slider (17; 24), which also has an opening (15, 16, 17; 24, 25) in the vicinity of each cyclone intake opening for passage of the fluid stream. The position and size of each slider opening is designed such that in various slider settings, the fluid stream will reach a different number of cyclone intake openings.

Connection device and process for connecting a hydrocyclone to a distribution and collection device, in which distribution and collection device includes connection openings for addition or removal of liquid during operation of the hydrocyclone. Connection device includes a pipe piece having an insertion side structured and arranged to be insertable through one of the connection openings into distribution and collection device. The insertion side includes a circumferential groove and a radial protrusion positioned adjacent circumferential groove, and radial protrusion has an outer diameter smaller than an inner diameter of the one connection opening and is structured to remain within distribution and collection device. A ring-shaped seal, structured and arranged to extend from exterior of distribution and collection device to interior of distribution and collection device, has an outer diameter greater that inner diameter of the one connection opening, and ring-shaped seal is positionable in a tensioned state in circumferential groove.

Methods and apparatus are provided for separation of liquids of different densities in production fluid streams from underground wells. Methods and apparatus are also provided for separation of gas, oil and water in production fluids, transportation of the separated fluids to the surface, as well as reinjection of separated water from the production fluids into other formations. Other aspects include new separation arrangements which include gas or liquid driven motors, designs for multi-stage hydrocyclone separators and use of beam or rod pumps.

A downhole fluid separation system comprises a fluid separator having a fluid inlet, a first fluid outlet, and a second fluid outlet, with a sensing device for sensing at least one parameter of a first component of a fluid mixture introduced into the fluid inlet of the fluid separator. The ratio of the first component to a second component of the fluid mixture is adjusted as such fluid mixture is introduced into the fluid inlet of the fluid separator in response to a signal provided by the sensing means. By adjusting the component ratio before the fluid is introduced into the fluid separator in response to a signal from a downhole sensing device, acceptable separation efficiency can be achieved over a broad range of fluid component ratios for a given fluid separator.
摘要:
A centrifugal separator has a plurality of substantially planar walls, including a first wall, defining a vortex chamber having an interior gas volume and for establishing at least one gas vortex in the gas volume, and the gas volume has a cross section that is distinctly non-circular, (and preferably quadrate). In addition to conventional outlets the separator includes a gas inlet having at least one elongated jet-defining wall with a free end portion extending into the gas volume a first distance from the first wall, to define a gas jet that extends substantially tangentially to the gas vortex in the gas volume. An insert extends between the jet-defining wall free end portion and the first wall and defines a gas flow direction changing surface. The insert may be substantially solid refractory material, or include a number of cooling fluids circulating tubes, and a gas flow direction changing surface may be substantially planar or curved. The first distance is typically at least 50 mm, but less than 25% of the dimension of the wall perpendicular to the first wall. The jet defining wall and the gas direction changing surface may make an angle .alpha. between 20.degree.-80.degree. and the first distance may be between 0.2-5 times the width of the gas inlet. The height of the gas inlet is at least twice as great as its width.

A multiple hydrocyclone assembly includes a closed tubular vertical housing enclosing two concentric vertical cylinders which cooperate with the housing to define an inner cylindrical outlet chamber and concentric annular inlet and outer outlet chambers. Multiple hydrocyclones or cyclonettes are mounted in axially extending vertical rows and in corresponding radial positions in the cylinders from the outer surface the outer cylinder, and the housing and concentric cylinders are formed in sections which are coupled together in end to end relation. Individual cyclonettes can be removed and replaced after removal of one or more of the housing sections. In order to increase the pressure of the feed stock to be cleaned which is supplied to the cyclonettes in the upper portion or sections of the assembly, vertically extending flow channels are provided in the lower portion of the inlet chamber by omitting cyclonettes from the rows in the lower sections of the assembly.

A hydrocyclone plant comprises a great number of hydrocyclones (1) arranged in a plurality of separate assemblies (10, 10A, 10B). Each hydrocyclone assembly includes branch pipes (6, 6A), to which the hydrocyclones of the assembly are connected in parallel relationship to one another. There are main pipes (13) of the same number as that of the branch pipes of each assembly, the branch pipes of each assembly being connected to said main pipes, respectively. According to the invention, clamping means (8, 9) are provided for releasably clamping each hydrocyclone substantially transversely against at least one of the associated branch pipes (6, 6A) of the latter, and the individual assemblies include various numbers of hydrocyclones, for optimizing the desired capacity of the hydrocyclone plant.
