Abstract
A system for separation of gas and solid at least comprises a cyclone trapping device and a negative pressure waste gas treatment device. The cyclone trapping device has a gas inlet and outlet chamber and a cyclone separation chamber communicating with each other, and the gas inlet and outlet chamber has a gas inlet tube communicating with a process waste gas source and a gas outlet tube communicating with the negative pressure waste gas treatment device. A process waste gas generated by the process waste gas source is introduced into the gas inlet and outlet chamber through the gas inlet tube to generate cyclones, thereby separating a portion of solid particles from the process waste gas, and transmitting the process waste gas to the negative pressure waste gas treatment device through the gas outlet tube in order to further separate the remaining solid particles from the process waste gas.
