Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention provides a kind of fish meal processing waste gas purification apparatus as depicted in figs. 1 and 2, comprise air inlet 1, expansion chamber 2, condenser 9, condensation chamber 11, absorption tower 12 and absorbing liquid collecting pit 17, the side of expansion chamber 2 is provided with air inlet 1, the inside of expansion chamber 2 is fixed with polylith deflector 4, deflector 4 is obliquely installed, and deflector 4 is provided with through hole, the top of expansion chamber 2 is provided with the first shower 3, the below of expansion chamber 2 is provided with flue-dust retainer 5, the bottom of flue-dust retainer 5 is provided with discharge outlet 7, and discharge outlet 7 place is provided with screen pack 6, expansion chamber 2 is connected with condensation chamber 11 by conduit 8, the top of condensation chamber 11 is provided with condenser 9, condenser 9 is connected with the condenser pipe 10 of the inside of condensation chamber 11 with condensed water outlet pipe 20 by condensed water water inlet pipe 19, the condenser pipe 10 taking the shape of the letter U and arrange is provided with in condensation chamber 11, condensation chamber 11 is communicated with absorption tower 12 by conduit 8, the bottom on absorption tower 12 is provided with absorbing liquid collecting pit 17, the middle-end on absorption tower 12 is provided with the second shower 15, second shower 15 is communicated with absorbing liquid collecting pit 17 with water circulating pump 18 by circulation conduit 16, the upper end of the second shower 15 is provided with demister 14, the upper end on described absorption tower 15 is provided with exhaust outlet 13.
Operation principle, waste gas enters expansion chamber 2 by air inlet 1, the dust in waste gas is retained by deflector 4, the dust on deflector 4 is washed away again by the first shower 3, waste gas after process for the first time enters condensation chamber 11 by conduit 8, heat exchange process is carried out by condenser pipe 10, dust in waste gas and solid organic matters are processed again, waste gas through after-treatment enters absorption tower 12 by conduit 8, sulfurous organic compound in the absorbing liquid removing waste gas sprayed by the second shower 15, can by the pernicious gas removing in waste gas through three process, waste gas finally after process is discharged by exhaust outlet 13.
Find in real work, even if the gas of discharging through three process passes through detection still containing the sulfurous organic compound exceeded standard, through repeatedly studying discovery, the discharge main cause of sulfurous organic compound to be in absorption tower that waste gas gets rid of excessive velocities and waste gas fails fully to mix with absorbing liquid to contact, and causes that relatively large waste gas is too fast is escaped by absorption tower thus take relatively large sulfurous organic compound out of.For this technical problem, the basis of aforementioned structure makes further improvements inside, absorption tower.As shown in Figure 1, inside, absorption tower is provided with the air storing cavity 19 of taper, and the surface of air storing cavity 19 is provided with steam vent 20, and the conduit 8 entering absorption tower is connected with air storing cavity 19.After adopting this structure, the absorbing liquid that second shower 15 sprays covers the surface of taper air storing cavity 19, the waste gas of being discharged by steam vent 20 fully can contact with absorbing liquid, thus can ensure that the sulfurous organic compound in waste gas is adsorbed to fall completely, ensure that the content of sulfurous organic compound in the gas that exhaust outlet 13 is discharged greatly reduces.Compare through experiment, in absorption tower, install taper air storing cavity additional compare with the absorption tower not installing air storing cavity additional, be vented the sulfurous organic compound in body content can reduce by more than 70%, effect is fairly obvious.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; although with reference to previous embodiment to invention has been detailed description; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
