On the basis of the above embodiments, the present invention continues to describe the technical features and functions of the technical features in the present invention in detail to help those skilled in the art fully understand the technical solutions of the present invention and reproduce them.
The upper cylinder 2 comprises a cover body 1 positioned at the top end, the cover body 1 is used for fixing a liquid inlet pipe 11 and a spiral driving shaft 12, and the spiral driving shaft 12 can rotate around the connecting position of the spiral driving shaft and the cover body 1 so as to drive a spiral blade arranged at the bottom of the spiral driving shaft to rotate. In the present invention, the liquid inlet pipe 11 can be used to connect with a liquid delivery device for pumping purified liquid, and is used to pump the liquid for adsorbing sulfur dioxide, nitrogen oxide gas and fixed particles into the upper cylinder 2.
In the invention, the upper cylinder 2 is provided with a conical distribution plate 14 formed by a conical structure on the bottom end surface, and a plurality of distribution holes formed by through holes are distributed on the conical distribution plate 14. A spiral stirring blade 15 is arranged in the inner space formed by the conical distribution plate 14, and the spiral stirring blade 15 is driven by the spiral driving shaft 12 to rotate. The rotation of the spiral stirring blade 15 can distribute the liquid fed in the liquid inlet pipe 11 in the middle cylinder 5 through the distribution holes on the conical distribution plate 14.
In the present invention, the middle cylinder 5 is located between the upper cylinder 2 and the lower cylinder 7. A support rod 16 for supporting the upper end surface of the middle cylinder 5 and the lower end surface of the upper cylinder 2 and reserving a gap is arranged between the upper end surface and the lower end surface. The support rod 16 can leave a sufficient gap for the air flow between the two to ensure that the air flow can be guided from the middle cylinder 5 to the outer cylinder 3 through the conical distribution plate 14 (i.e. in the air channel formed between the inner surface of the outer cylinder 3 and the outer surface of the middle cylinder 5).
In the invention, a lower cylinder 7 is arranged below the middle cylinder 5, and fan blades 9 are arranged in the lower cylinder 7. The fan blades 9 rotate under the action of the fan blade driving shaft 10, so that a certain wind force effect is formed between the lower cylinder 7 and the middle cylinder 5, liquid falling down through the conical distribution plate 14 in the upper cylinder 2 is delayed, the contact time between the liquid and gas to be treated is prolonged, and the liquid adsorption effect is further improved. It should be noted that the wind direction generated by the fan blades 9 by rotation and attached to the middle cylinder 5 is opposite to the direction of the flue gas to be treated entering from the tangential direction of the lower cylinder 7, so that the problem that the flue gas enters the outer cylinder 3 after the residence time in the middle cylinder 5 is short can be avoided.
In the invention, the bottom of the lower cylinder 7 is provided with a bottom support plate 8 which is formed by a sector plate with a through hole and surrounds the central axis of the lower cylinder 7. The bottom support plate 8 is used for fixing the fan blade driving shaft 10 and connecting the shaft seat of the fan blade driving shaft 10 with the lower cylinder 7. The effect of using the above structure is also that, since the liquid is dropped from the upper cylinder 2, it means that the dropped liquid is dropped in the lower cylinder 2 after coming into contact with the flue gas, the above structure of the bottom support plate 8 can prevent the liquid from accumulating there.
In the present invention, the inlet of the outer cylinder 3 is installed between the upper cylinder 2 and the middle cylinder 5, that is, after the flue gas contacting with the liquid runs to the conical distribution plate 14 at the top, the flue gas can diffuse to the periphery of the middle cylinder 5 until entering the outer cylinder 3 through the gap between the two. The outer cylinder 3 can be firstly lapped on the clamping platform 20 of the middle cylinder 5 and then fixed on the middle cylinder 5 by welding. The outer barrel 3 is connected with the contact surface of the upper barrel 2 through a corrosion-resistant sealing element, so that the flue gas is prevented from overflowing from the connection position of the outer barrel and the upper barrel on the premise of ensuring the detachable maintenance.
In the invention, a packing layer 4 is arranged at the outlet of the outer cylinder 3, the structure of the packing layer 4 is shown in fig. 6, and the packing layer comprises an inner sleeve 23 and an outer sleeve 22 which are coaxially arranged, a plurality of partition plates are arranged between the inner sleeve 23 and the outer sleeve 22, and the partition plates 22 form a cavity for containing the adsorbing material between the inner sleeve 23 and the outer sleeve 22. The adsorbing material is activated carbon or other materials which can play the same effect.
In the invention, the gas filtered by the filler layer 4 can be sent into the spraying chamber again for secondary spraying operation so as to remove harmful substances contained in the flue gas as much as possible, thereby achieving better dust removal effect. The fan blade driving shaft 10 and the spiral driving shaft 12 can be provided with driving wheels, and the purpose of power input is achieved through a transmission device.
Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
