摘要： A dust collecting system for single crystal growth system includes an air compressor, a dust collecting device, a first inert gas source, a rotary pump and a scrubber. The air compressor is fluidly connected to an exit pipe of the single crystal growth system. The exit pipe is used to exhaust unstable dust from the single crystal growth system. The dust collecting device is fluidly connecting to the exit pipe to collect the dust oxide. The first inert gas source is fluidly connected to the exit pipe to blow a first inert gas into the exit pipe to compel the dust oxide toward the dust collecting device. The rotary pump is fluidly connected to the dust collecting device. The scrubber is fluidly connected to the rotary pump. The rotary pump transports the residual dust oxide toward the scrubber. The present disclosure further provides a method for collecting dust.

摘要： The present invention addresses to a third stage system with self-bleeding by means of the use of an internally or externally installed ejector with application in all multicyclone systems operating at positive pressure, whether for application in particulate abatement or protection systems of turbo-expanders or in industrial units that involve the need of recovering solid products carried by the process gas, aiming at eliminating the need for any additional separation systems using cyclones or filters to carry out the bleeding of the cyclone legs.

摘要： The system extracts water from lunar regolith and includes a regolith intake having a digging bucket that collects lunar regolith soil and a gravel separator that separates and discharges gravel and passes a mixture of ice-regolith powder having ice grains that are about 10-100 microns along the conveyor. A pneumatic separator receives the ice-regolith powder and pneumatically splits the ice-regolith powder into streams of different sized lithic fragments and ice particles per the ratio of inertial force and aerodynamic drag force of the lithic fragments and ice particles. Each split stream may include a magnetic separator that separates further the magnetic and paramagnetic lithic fragments from ice particles to discharge up to 80 percent of lithic fragments to slag.

摘要： A surface cleaning apparatus comprises an air treatment chamber having a first end, an axially opposed second end, an axis extending between the first and second axially opposed ends and an axially extending air treatment chamber sidewall. The air treatment chamber air outlet is provided at the second opposed end and the first opposed end is moveably mounted between a closed position and an open position in which the air treatment chamber is open. The air treatment chamber has a stationary portion and an openable portion and the openable portion is moveably mounted between a closed position and an open position in which the air treatment chamber is open. When the openable portion is in the closed position, the openable portion and the stationery portion abut along peripheral edges that extend along a length of the air treatment chamber sidewall.
