The inspection door is communicated with the interior of the ash collecting hopper and is respectively arranged without interfering with the telescopic device and the flap actuator.
5. The method for using an adjustable counter-hedge semi-dry tower according to claim 4, characterized in that The following steps are involved: Step 1: Under the premise of ensuring that the tower body is of sufficient height, according to the change of the calorific value of the garbage components, the height of the inner cone bucket in the tower body is adjusted by the hydraulic cylinder, thereby adjusting the deacidification reaction time of the flue gas in the tower body; Step 2: The large-sized fly ash in the flue gas falls into the inner cone bucket due to its own weight, and the deacidified flue gas is discharged through the flue gas inner outlet and the flue gas outer outlet in turn; Step 3: After the fly ash in the tower body is accumulated in the inner cone bucket after a long period of operation, the first flip assembly and the second flip assembly respectively control the opening and closing of the upper wall plate of the inner cone bucket and the lower wall plate of the inner cone bucket to form a falling channel; Step 4: The accumulated ash in the inner cone bucket naturally falls through the falling channel to the ash collecting hopper for collection, and then is unloaded through the ash collecting port of the ash hopper.
