A natural-circulation self-cleaning evaporation device is disclosed. A steel wire screw is mounted in an uplink heating pipe; a twisted strip screw is mounted in a downlink heating pipe. Fluidization balls are added into a circulation solution to realize high-efficient cleaning by the fluidization balls with a low concentration of 0.1%-3.0% in a spiral fluidization state. A boiling pipe is disposed above a heating chamber, is trumpet-shaped, prevents fluidization ball obstruction by adopting a converged section and a gradually-expanded section, and reduces the circulation resistance and the outlet kinetic energy loss. A shunting skirt is designed at the lower end of a lower pipe plate of the heating chamber. The circulation solution flowing downwards is shunted into a circulation main flow and a circulation auxiliary flow before the shunting skirt; the circulation auxiliary flow flows into and stirs the fluidization balls to form a fluidization state when passing through sieve pores on a sieve plate, which allows the fluidization balls to flow into the uplink heating pipe uniformly and smoothly, so as to realize natural circulation flow of the fluidization balls. The spiral-fluidization self-cleaning evaporation device can not only realize natural circulation, but also realize high-efficient automatic cleaning, is reliable in operation, simple in maintenance, and thus can realize both great yield increase and energy saving.
