Preferably, the liquid medicine after the circulation fluid dispensing box will wash through the interior flashboard of establishing carries out filtration treatment twice.
Preferably, the slope that is used for the sediment cleaning is established in circulation fluid dispensing box bottom, and soil cleaning port is established in the bottom, slope.
Preferably, overfall is established near the purifying column exit in circulation fluid dispensing box top, is used to discharge the floating thing that gets into the circulation fluid dispensing box.
Preferably, it is cylindric that purifying column is, and its outside installing has the manhole of lucite visor.
Compared with prior art, the present invention has following beneficial effect:
1, the setting of packing layer and spray system in the purifying column can make the reaction of waste gas and liquid medicine more abundant, avoids environmental pollution;
2, fan trouble and the potential safety hazard effectively having avoided tar to be attached to causing on the axial flow blower;
3, the water of purifying exhaust air can be recycled, and economizes on resources;
4, can adjust the type that purifies medicament through the pH value that detects in the liquid medicine, simple and convenient;
5, the slanting baffle at purifying column exhaust gas inlet place is designed with and is beneficial to the waste gas wind direction and is adjusted to direction from bottom to top, makes reaction efficiency higher;
6, entire equipment small investment, purification efficiency is high, compact conformation, easy operating management.
Description of drawings
Fig. 1 is the connection sketch map of sand mold mo(u)lding line cooling duct waste gas purification treatment facility of the present invention.
In conjunction with the accompanying drawing following Reference numeral of mark above that:
Be connected pipeline between the 1-cooling duct, 2-cooling duct and purifying column, be connected pipeline between 2A-purifying column and the circulation fluid dispensing box, the pipeline that is connected of 2B-purifying column and blower fan; The 3-purifying column, the spherical filtrate of 4-, 5-slanting baffle, 6-annular spray system; 7-circulation fluid dispensing box, 8-overfall, 9-dosing mouth, 10-flashboard; The 11-soil cleaning port, 12-discharge outlet, 13-circulated sprinkling pump, 14-blower fan.
The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of the specific embodiment.
As shown in Figure 1, mo(u)lding line cooling duct waste gas purification treatment facility of the present invention is used for the exhaust-gas treatment when the core casting cooled off, and mainly comprises purifying column 3, circulation fluid dispensing box 7, blower fan 14 and connects pipeline accordingly.
Purifying column 3 profiles are cylindrical; Its outside is equiped with manhole, and manhole has machine glass visor, and there is a slanting baffle 5 at purifying column exhaust gas entrance place; Establish twice annular spray system 6 and three layers of filler conversion zone in the purifying column 3, fill spherical filtrate 4 in the filler conversion zone.
