Abstract
The system includes a dust collector, a pressure controller, a dryer, a gas heat-insulation device, a gas pool, a gas detector, an optical monitor and a computer sequentially connected. The dust collector is used to filter solid particles in a gas. The pressure controller is used to control a flow rate of the gas. The dryer is used to control a humidity of the gas. The gas heat-insulation device is used to control a temperature of the gas. The gas pool is used to carry the gas. The laser is used to irradiate the gas in the gas pool to generate a Raman scattering light. The gas detector is used to collect the Raman scattering light. The optical monitor is used to adjust and amplify a light signal of the Raman scattering light. The computer is used to output a Raman spectrum and a composition and content of a tar.
