Spraying type saturator and working method thereof

The invention relates to a spray type saturator and a working method thereof, the spray type saturator comprises a separation chamber and a crystallization chamber, and the separation chamber and the crystallization chamber are communicated through a downcomer; a reverse spraying pipe and an empty spraying pipe are arranged at the upper part of the separation chamber; the upper end of the reverse spraying pipe is a coal gas inlet, and the lower end is internally provided with a primary mother liquor nozzle; the inlet of the pipeline extends out of the side part of the separation chamber; a coal gas outlet is formed in the upper end of the air spray pipe, and a secondary mother liquor spray head and a demister are sequentially arranged in the air spray pipe from bottom to top; the inlet of the pipeline extends out of the side part of the empty spraying pipe; and the primary mother liquor spray head is a dynamic wave spray head. The demister has the advantages of low power consumption, high demisting efficiency
