The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1, tail gas recovery tower; 2, filler; 3, water circulating pump; 4, tail gas admission line; 5, fluid pipeline; 6, liquid-circulating pipeline; 7, chilled water pipeline; 8, ethanol collection conduit; 9, purified gas outlet.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only be used to explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, comprise tail gas recovery tower 1, water circulating pump 3 and connecting pipe, it is characterized in that, described connecting pipe comprises tail gas admission line 4, fluid pipeline 5, liquid-circulating pipeline 6 and ethanol collection conduit 8, described tail gas recovery tower 1 comprises is located at respectively bottom, the air inlet at top and top, inlet and purified gas outlet 9, described tail gas recovery tower 1 inside is provided with filler 2, described tail gas admission line 4 is connected with described air inlet, described fluid pipeline 5 connects the entrance of described water circulating pump 3, described liquid-circulating pipeline 6 connects respectively the outlet of described water circulating pump 3 and the inlet of tail gas recovery tower 1, described ethanol collection conduit 8 is connected with described liquid-circulating pipeline 6.
On described liquid-circulating pipeline 6, also be provided with chilled water pipeline 7.
Described filler 2 is efficient stainless steel cloth.
Ethanol device for recovering tail gas of the present utility model is work like this, the waste gas that contains alcohol gas enters the bottom of tail gas recovery tower 1 along tail gas admission line 4, on tail gas, ease is carried out mass transfer on the surface of the interior filler 2 of tail gas recovery tower 1, alcohol gas is dissolved in by liquid-circulating pipeline 6 and enters in the chilled water of tail gas recovery tower 1, waste gas and chilled water reverse flow.Purified gas is discharged by the purified gas outlet 9 of tower top.The chilled water that contains ethanol pumps into tail gas recovery tower 1 along fluid pipeline 5 again through water circulating pump 3, recycles.When in chilled water, ethanol content reaches finite concentration, by ethanol collection conduit 8, be expelled to destilling tower and reclaim ethanol.Fresh food frozen water, also enter tail gas recovery tower 1 together by chilled water pipeline 7 feeding-in liquid circulating lines 6, reaches the purpose of supplementing chilled water, constant with the gas liquid ratio that guarantees tail gas recovery tower 1.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
