Particulate-containing exhaust gas treatment device and method

Abstract

A kind of tail gas treatment device and method containing particle, in the device, convection washing system washes the particle and chemical substance in absorption tail gas and reduces tail gas temperature, the absorption liquid of washing tower flow and the tail gas from dust collection reservoir form counterflow in water rush convection pipe to absorb the particle and chemical substance in tail gas while reducing tail gas temperature, slow down the slow-down ball in deceleration convection bin for slowing down the flow rate of absorption liquid and tail gas;Multi-layer graphite dust collection tank is connected by pipeline to spray bin to absorb the particle in tail gas from washing tower, intestinal water curtain absorption system is connected by pipeline to multi-layer graphite dust collection tank to wash the chemical substance in tail gas and reduce tail gas temperature, intestinal water curtain absorption pipe is back-to-back reciprocating structure, a pair of upper and lower symmetrical water curtain nozzles for forming water curtain filled with pipe section are arranged in every distance in the overall inclined reciprocating structure.The device is flexible to install, high in absorption efficiency and small in floor space.
