Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1 and 2, a tail gas treatment system of a fumed silica production device comprises an absorption tower 2 connected with a tail gas conveying pipeline 1, wherein a plurality of obliquely arranged tower plates 3 are arranged in the absorption tower 2, a plurality of small holes 4 are formed in the surfaces of the tower plates 3, the bottom of the absorption tower 2 extends into the liquid level of a sewage tank 5, the sewage tank 5 is connected with the liquid inlet end of the absorption tower 2 through a circulating pipeline 6, a centrifugal pump 7 is arranged on the circulating pipeline 6, a cleaning hole 8 is formed in the side wall of the absorption tower 2 corresponding to each tower plate 3, and the cleaning hole 8 is matched with a plug 9.
Preferably, the tail end of the tail gas conveying pipeline 1 is transversely provided with a tail gas dispersion pipe 10, and the upper surface of the tail gas dispersion pipe 10 is uniformly provided with gas dispersion holes 10.1. The tail gas entering the absorption tower 2 can be effectively and uniformly distributed through the gas dispersing holes 10.1 of the tail gas dispersing pipe 10, and the phenomenon that the tower plate 3 is impacted by overlarge gas flow or the absorption of the tail gas is uneven is avoided.
Preferably, a liquid outlet of the circulating pipeline 6 is transversely provided with a liquid dispersion pipe 11, and the lower surface of the liquid dispersion pipe 11 is uniformly provided with liquid dispersion holes 11.1. The liquid holes 11.1 of the liquid dispersion pipe 11 can uniformly disperse the liquid entering the absorption tower 2 and then fall into the tower plate 3, so that the contact area between the liquid dispersion pipe and the tail gas is increased, and the absorption efficiency is improved.
Preferably, an overflow hole 12 is further formed in one side of the sewage tank 5, an overflow groove 13 is formed below the overflow hole 12, the overflow groove 13 is connected with the circulating pipeline 6 through a pipeline, and a water replenishing pipe 5.1 is arranged above the sewage tank 5. The bottom of the absorption tower 2 extends into the liquid level of the sewage tank 5 to form a liquid seal, so that the tail gas can be prevented from directly escaping from the bottom of the absorption tower 2, water can be supplemented into the sewage tank 5 through the water supplementing pipe 5.1, the height of the overflow hole 12 can be set to be higher than the bottom of the absorption tower 2, when the liquid level exceeds the height of the overflow hole 12, the liquid can overflow from the overflow hole 12 and then flows into the overflow groove 13, at the moment, the liquid level in the sewage tank 5 can be determined to be higher than the bottom of the absorption tower 2, manual operation is not needed all the time, only the increase of the liquid in the overflow groove 13 needs to be observed, when the liquid in the overflow groove 13 is accumulated to a certain amount, a valve on a pipeline can be opened, and then the liquid in the overflow groove 13 can be pumped into the absorption tower 2 through the centrifugal pump 7.
Preferably, a filter screen 14 is further provided at a position where the sump 5 is connected to the circulation line 6. The filter screen 14 can effectively prevent the particulate matter in the sump 5 from being drawn into the centrifugal pump 7 and causing clogging.
The working principle of the embodiment is as follows:

If the small hole 4 of column plate 3 takes place to block up and other problems at the circulation absorption in-process, can dismantle end cap 9 of washing hole 8 and wash the work of column plate 3, guaranteed that the device normally operates and absorbs, this mode is simple high-efficient, and tail gas after the processing is discharged from the absorption tower 3 top, and the liquid that is located sewage tank 5 can discharge to next process through the drain pipe of bottom and recycle or relevant processing. In this embodiment, the plug 9 may be a plug-like structure or may be connected to the cleaning hole 8 by a bolt.
The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope.
