Abstract

The invention discloses a portable granulation tail gas dust removal device which comprises a supporting device, a steam flushing device and an efficient blade demister. Wherein the supporting device is designed to be of a hollow structure and is necked down from bottom to top, so that the circulation resistance of gas in the space is reduced; according to the blade distance adjusting mechanism of the efficient blade demister, the distance between a lead screw fixing block and a lead screw moving block can be adjusted, and then the distance between adjacent blades can be accurately adjusted; and the spraying device is fixedly mounted on the supporting device and is positioned below the efficient blade demister. A modular design concept is adopted, and an efficient blade demister, a steam flushing device and a spraying device are integrated. Wherein the blades of the efficient blade demister are connected in an inserted mode, and the steam flushing device is connected with the pipeline of the spraying device through a flange connector. Due to the design, the whole device can be quickly assembled and disassembled, and the convenience of maintenance and upgrading is greatly improved.
