[0003] Currently, there is a method of filtering dust in exhaust gas through liquid absorbent, but after the liquid absorbent is saturated with dust, the adsorption effect of the liquid absorbent will deteriorate. Therefore, it is necessary to stop the introduction of exhaust gas and replace the new liquid absorbent before introducing the exhaust gas. This is not convenient for continuously separating the dust in the exhaust gas, resulting in poor separation effect. After the exhaust gas is introduced into the liquid absorbent, the exhaust gas and the liquid absorbent are not mixed sufficiently, and the exhaust gas is not dispersed enough when it is introduced into the liquid absorbent, which will reduce the effect and efficiency of dust separation in the exhaust gas.
