摘要:
Systems and methods for separating particles from fluids are provided. The system comprises a vessel with at least two fluid inlets and a fluid outlet wherein one fluid inlet is positioned higher in the vessel than the other fluid inlet. The fluid inlets may be connected to a polymerization reactor and each fluid inlet may be configured to deliver fluid to the vessel from a different zone of the polymerization reactor. During shut-down of a polymerization reactor, reaction mixture is discharged to a separation system where polymer particles are removed from the mixture prior to being released into the atmosphere.

A particle separator assembly connectable to a fluidized reactor includes a vertical vortex chamber enclosed by water tube panel walls forming a polygonal horizontal cross section and a supporting structure of the water tube panel walls. The polygonal horizontal cross section has at least six corners and the supporting structure has at least one horizontally arranged circular beam arranged outside of the water tube panel walls and attached by radially extending fasteners to at least three of the water tube panel walls. The at least one circular beam forms a full circle, or the at least one circular beam forms a partial circle covering at least seventy-five percent of a full circle and has ends that are firmly attached to a rigid support construction.

A cyclone separator for phase separation of a fluid stream has a rotationally symmetrical housing with a hollow chamber. Feed lines feed the fluid stream into the housing substantially tangentially. At least one discharge line conducts the separated gaseous fraction. In order to ensure uniform and homogeneous flow distribution of the steam to be heated as it enters the heating phase, the hollow chamber, when viewed in the radial direction from the mid-axis, has an outflow chamber with a circular cross section and, in radial sequence, a heating chamber, an intermediate chamber, a dryer chamber and an inflow chamber. The inflow chamber is outwardly delimited by the housing. The heating chamber contains heating elements for heating the gaseous fraction. At least one fine separator and at least one associated condensate-collecting trough are arranged in the dryer chamber. The condensate-collecting trough is connected to a condensate discharge pipe in the intermediate chamber for conducting the condensate forming in the fine separator out of the hollow chamber.

A refrigeration system that includes at least one semi-closed air-refrigerated chamber and an air-cycle refrigeration loop for drawing air from the refrigerated chamber(s), cools the air, and returns the now-cooled air to the refrigerated chamber(s). The refrigeration loop includes various compression, expansion and heat transfer stages for cooling the air drawn from the refrigerated chamber(s). The air within the refrigerated chamber and air infiltrating into the refrigerated chamber(s) will typically contain moisture. A positive-pressure cyclone separator located between a final expansion stage and the refrigerated chamber(s) removes snow created in the final expansion stage due to moisture in the air drawn from the refrigerated chamber(s).

A dust collecting apparatus for a vacuum cleaner separates dust and liquid particles from intake air. In an embodiment, the apparatus has a cyclone body with a cylindrical part including an air inlet passage and an air outlet passage, a tapered part, and a contaminant receptacle coupled to the tapered part of the cyclone body. The tapered part has a diameter that decreases from the cylindrical part toward the contaminant receptacle. In some embodiments, a screen with holes sized to pass liquid particles is disposed inside the cyclone body, so that liquid particles and dust are separated during operation.

A dust collecting apparatus for a vacuum cleaner, for separating dust and moisture from external air, comprises a cyclone body having an air inlet and an air outlet, a screen mounted in the cyclone body and having a plurality of moisture passing holes, and a dust receptacle engaging the cyclone body to collect therein the dust and moisture separated from the air.
摘要:
A cyclone condensing apparatus having a structure in which air of high-temperature and high-humidity sufficiently contacts cooling water, and condensed water is efficiently discharged to the outside, and a washing/drying machine having the cyclone condensing apparatus. The cyclone condensing apparatus includes an air inlet connected to the upper part of a casing having a conical shape along a tangential direction; an air outlet disposed along the central line of the casing, and a plurality of cooling water spray nozzles disposed along the circumferential direction of the casing. A spiral groove for guiding condensed water downwards is formed in the inner circumferential surface of the casing, and a water-collecting container for collecting the condensed water is connected to the lower end of the casing. The cyclone condensing apparatus further includes an air blast fan and a heater in the washing/drying machine, and is connected to an air circulating duct forming a closed circuit together with a dry tub, thereby condensing water from air of high-temperature and high-humidity passed through the dry tub.
