Novel defroster's working method:
when the demister works, the smoke firstly passes through the three-dimensional crossed wire mesh structure at a high speed, and most of liquid drops in the smoke can be captured due to the criss-cross wire mesh crossed structure in the smoke. After the smoke passes through at high speed, the gas moves at high speed to generate upward force to push fan blades in the automatic fan device to rotate around the supporting shaft. Because the silk screen design in the middle of the flabellum, in the rotation process, the liquid drop in the smoke can be captured, and the evaporation of the liquid drop on the leaf silk screen and the three-dimensional crossed silk screen structure below the leaf silk screen can be accelerated through the wind direction generated by the rotation of the flabellum, so that the liquid drop is captured secondarily and the silk screen is fully protected. The defogging type flabellum of two fans on the left and right sides is partial to the tube shell design of relative both sides respectively, and this is for blowing partial flue gas to the inlayer folded plate of both sides tube, (inlayer folded plate design is through increasing folded plate surface area to catch more liquid drops) through the effect of high-speed striking, gets rid of the liquid drop in the flue gas on the surface of double-deck folded plate, thereby carries out the seizure of third time liquid drop, in order to reach the effect that improves separation efficiency. Finally, a small part of liquid drops remained on the folded plate enter the liquid discharge channel through the liquid drop opening at the bent part of the inner layer folded plate to be discharged.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
