In the invention, an access door 5 is arranged on one side of the conical surface of the ash collecting hopper 4, as shown in figure 1, the access door 5 is communicated with the interior of the ash collecting hopper 4 and is arranged without interfering with the expansion device 11 and the turnover plate actuating device 12 respectively. In the process of shutting down the equipment, the dust removing device can enter the dust collecting hopper 4 through the access door 5 to carry out dust removing and equipment maintenance and repair work, in particular to the maintenance and repair of the telescopic device 11.

The invention discloses a using method of a novel efficient adjustable hedging type semi-dry tower, which comprises the following steps:

the method comprises the following steps: firstly, on the premise of ensuring that the height of the tower body 2 is enough, the height of the inner cone hopper 3 in the tower body 2 is adjusted through the hydraulic cylinder 111 according to the change condition of the heat value of the garbage components, and further the deacidification reaction time of the flue gas in the tower body 2 can be adjusted according to the actual working condition;

step two: the large-particle size fly ash in the flue gas falls into the inner cone hopper 3 due to the self weight of the fly ash, and the deacidified flue gas is discharged through the flue gas inner outlet 7 and the flue gas outer outlet 10 in sequence, so that the low emission standard of acidic substances in the flue gas is realized;

step three: after the fly ash in the tower body 2 is accumulated to the inner cone hopper 3 through long-time operation, the opening and closing of the upper-layer wallboard 31 and the lower-layer wallboard 32 of the inner cone hopper are respectively controlled through the first overturning assembly and the second overturning assembly, and a falling channel is formed;

step four: the accumulated ash in the inner cone hopper 3 naturally falls into an ash collecting hopper 4 through a falling channel for concentration, and then is discharged through an ash collecting port 6 of the ash hopper.

The invention has the beneficial effects that:

(1) on the premise of ensuring that the height of the tower body 2 is enough, the height of the inner cone 3 in the tower body 2 can be adjusted through the telescopic device 11 according to the change situation of the heat value of the garbage component, so that the reaction time of the flue gas in the tower body 2 is adjusted, the low emission standard of acidic substances in the flue gas is ensured, and the flue gas deacidification efficiency is improved;

(2) after the fly ash in the tower body 2 is accumulated to the inner cone hopper 3 after a long time of operation, the turning plate execution device 12 can respectively drive the opening and closing of the upper wall plate 31 and the lower wall plate 32 of the inner cone hopper, so that a falling channel is formed, the accumulated ash is concentrated in the ash collecting hopper 4, the fly ash is conveniently discharged, and the dust content in the smoke is reduced.

The above-mentioned embodiments are merely descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention, and various modifications and improvements made to the technical solutions of the present invention by those skilled in the art should fall into the protection scope of the present invention without departing from the design concept of the present invention, and the technical contents of the present invention as claimed are all described in the technical claims.
