Abstract
The invention discloses a waste gas treatment device which mainly comprises a cooling pipeline, a waste gas pipeline, a purifying tower, a purifying pipeline, a water inlet pipeline, a water pump, a manual chemical adding box, a water pond, a pollution-discharging and pure-gas-charging hole, a flashboard, an overflow hole, an exhaust chimney and a fan, wherein waste gas enters a pressure equalizing chamber from a fan sucking and purifying tower, and is in full contact with water vapor by means of a first annually spraying and oppositely-sprinkling region. Mass transfer is generated, and then the waste gas moves back and enters a second filler spraying reaction region in a variable speed manner, the waste gas is subjected to full contact of a gas phase and a liquid phase by means of reaction of an inverted-spraying and functional filler layer, so that a mass transfer neutralization reaction is generated. Such treated waste gas enters a third inverted-spraying and functional filler layer for reaction so that the waste gas is fully purified, then demisted by an upper tower body filler demister, subjected to fluid exhaustion, and discharged into atmosphere by means of a fan. According to the waste gas treatment device, the waste gas of the cooling pipeline can be effectively purified, the environment pollution is prevented; coke is prevented from being attached on an axial flow fan, and the caused fan failure and the potential safety hazards are prevented.
Description
Technical field
The present invention relates to casting technology field, particularly relate to a kind of emission-control equipment.
Background technology
In the sand casting of casting automatic production line benevolence.Casting mold after usual cast can produce the waste gas containing toxic gases such as flue dust, tar, carbon monoxide and sulfur dioxide, and these materials can cause fan trouble after entering people's cooling duct with casting mold and there is the hidden danger such as environmental pollution.At present, the scheme of exhaust-gas treatment has following several: one is that axial flow blower is in line; Program cost is lower, but to environment, and tar witheredly can be attached on axial flow blower and easily causes fan trouble, and cooling duct temperature is high, there is the potential safety hazard of tar burning.Two is charcoal absorptions; This scheme result is more satisfactory, but active carbon needs often to change regeneration, and cost is high, complex process.Three is that pipeline spray lime or spray dust-removing powder absorb sedimentation; This scheme cost is low, but device structure is more complicated, and regulation effect is general, and lime used and dust-removing powder amount are comparatively large, easily produce secondary pollution.
The disadvantage existed in above-mentioned each scheme or for poor processing effect, have potential safety hazard, or for cost high. or for there is secondary pollution.
Summary of the invention
According to above deficiency, the invention provides the emission-control equipment that a kind of structure is simple, control slender type decorative circle assemblage gap.
For achieving the above object, emission-control equipment of the present invention, main contents are: comprise cooling duct, exhaust piping, purifying column, purification pipeline, inlet channel, water pump, artificial dosing tank, pond, blowdown drain, flashboard, overfall, exhaust chimney and blower fan, described device adopts NaOH solution as cyclic absorption neutralizer; Described waste gas is inhaled people purifying column by blower fan and is entered pressure chamber per capita, through first annular spray to spray region, waste gas is fully contacted with aqueous vapor.Mass transfer occurs, and then waste gas speed change is moved back to into people's second filler spray reaction zone, through inverse spray and the reaction of functional stuffing layer of spray, makes waste gas obtain the abundant contact of gas-liquid two-phase, mass transfer neutralization reaction occurs.Waste gas treated like this enters inverse spray and the reaction of functional stuffing layer of people the 3rd road spray again, and through the demist of upper tower body filler demister after making waste gas fully purify, de-liquid process, then via blower fan row people air.
Beneficial effect of the present invention can effectively purify cooling duct waste gas, avoids environmental pollution; Having stopped tar is attached on axial flow blower, the fan trouble caused and potential safety hazard; Technique is simple, and filtrate cost used is low; Purify waste water and can be recycled, economize on resources, cost-saving; Complete equipment small investment, compact conformation, floor space are little, purification efficiency is high, are easy to oam.
