Abstract

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.
