Mark among the figure: sub-caustic wash tower 1, expansion joint 2, waterproof air-breather 3, breather pipe 3.1, support 3.2, bucker 3.3, valve 4, passage 5, alkali lye storage tank 6, pump 7.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 2, the utility model is specifically related to a kind of tail gas alkaline cleaning tower.This tail gas alkaline cleaning tower; Comprise at least two sub-caustic wash towers 1; The inlet of said sub-caustic wash tower 1 is connected with the outlet of alkali lye storage tank 6 through pump 7, and the liquid outlet of sub-caustic wash tower 1 is connected with the import of alkali lye storage tank 6, the overlapping vertically setting of said sub-caustic wash tower 1; The sub-caustic wash tower of the bottom of said sub-caustic wash tower 1 and next stage is provided with passage 5 between 1 top, and passage 5 places of said sub-caustic wash tower 1 bottom are provided with waterproof air-breather 3.
This tail gas alkaline cleaning tower comprises at least two sub-caustic wash towers 1, and said sub-caustic wash tower 1 is along the overlapping setting of axis direction; The floor space of saving equipment reduces the waste to the soil, has practiced thrift cost; When equipment is carried out craft piping,, do not receive the restriction of horizontal space because equipment vertically is provided with; Reduced the use of pipeline, pipe arrangement is more flexible simultaneously, has practiced thrift the space.After tail gas is got into from sub-caustic wash tower 1 bottom; Output gets into the tail gas clean-up stage from the caustic wash tower top after can carrying out mass transfer with alkali lye from bottom to top; The sub-caustic wash tower of the bottom of said sub-caustic wash tower 1 and next stage is provided with passage 5 between 1 top, and the inner chamber of a plurality of sub-caustic wash towers 1 is interconnected.Because splendid attire is used for the alkali lye of mass transfer in each sub-caustic wash tower 1; In order to prevent that alkali lye from passing through passage 5 and flowing into the caustic wash tower bottom from top to bottom; Tail gas can't be got into get into every grade of sub-caustic wash tower 1 successively; Passage 5 places at every grade of sub-caustic wash tower 1 are equipped with waterproof air-breather 3, and this waterproof air-breather 3 helps the eliminating of gas dispersion and alkali lye, thereby the efficient that improves gas-liquid mass transfer is enhanced productivity.Said waterproof ventilation device can be various ways; The said waterproof ventilation device 3 of the utility model comprises breather pipe 3.1 and the bucker 3.3 that is connected through support 3.2 with breather pipe 3.1 tops; Tail gas is discharged through the gap between the support 3.2; Alkali lye stops because of bucker 3.3, flows to sub-caustic wash tower 1 bottom, and discharges through liquid outlet.
