Abstract
The invention belongs to the field of waste gas treatment and relates to waste gas treatment process and equipment in the printing industry. The treatment process comprises three major parts, including a fan duct system, a humidifying tower and a biological purification tower. Waste gas in the printing industry is send to the humidifying tower by a fan and through exclusive pipe pumping, and after being humidified through the humidifying tower, waste gas enters to the biological purification tower. The biological purification tower is filled with biological stuffing attached with microorganisms. When the waste gas passes through the biological stuffing, the microorganisms on the biological stuffing can absorb and degrade various organic substances in the waste gas, so as to achieve the purpose of purifying the waste gas. After purification, the waste gas is nontoxic, smell-less and flavourless.
Description
Technical field:
The invention belongs to exhaust-gas treatment field, it is related to a kind of printing industry waste gas treatment process and equipment.
Background technology:
Printing process needs apply substantial amounts of ink, the volatile malodorous material in ink can discharge and be discharged in air, cause atmospheric pollution, this kind of waste gas is negatively affected to surrounding and air quality if do not carried out effective place and comprehending.
Printing industry ink exhaust-gas treatment present situation:
Also there is no a kind of effective processing method to the waste gas of printing industry at present, this kind of waste gas mainly contains some volatile organic matters (voc), the odorant such as benzene class, ketone.The processing method at present printing industry waste gas commonly used is activated carbon adsorption；Although activated carbon adsorption can adsorb the voc in waste gas, play the effect of certain removal voc and deodorization；But activated carbon adsorption is easily saturated, saturation behind efficiency reduces, even without positive effect.In order to keep effect, constantly replacing or the regeneration of activated carbon needs, this process complexity and somewhat expensive；Activated carbon adsorption is also had also to there is the big problem of resistance, so some activated carbon adsorption equipment, with the near future, tend not to normally run, simply just as ornaments.
Content of the invention:
For the shortcoming overcoming current printing industry exhaust-gas treatment to exist, the present invention to process this kind of waste gas using the method for biofiltration.Microorganism can be with the pollutant in waste gas as nutrient, and own growth breeding, metabolism are it is not necessary to changing or regenerating；Voc in waste gas can be degraded into co by microorganism2And water；And can steady in a long-term and Effec-tive Function, play deodorization, the target of qualified discharge；This process is easy and simple to handle, easy to maintenance.
The technical solution used in the present invention:
1. technological process；
Arrange outside waste gas after printing industry waste gas → blower fan → humidification tower → biological purifier → cleaning.
2. technological process explanation:
(1) Fan pipeline system: machine room's waste gas is pumped to humidification tower through Fan pipeline.
(2) humidify tower:
The main purpose of humidification tower is to humidify waste gas, makes the moisture content in waste gas reach degree of saturation, and this is the biodegradation necessary moisture content of offer for waste gas.Humidification tower can adopt circular structure, and gas enters from bottom, from above out, have water sprinkler system, have water pump, bottom to have collecting-tank in humidification tower, the nozzle having water pipe and being contained in humidification top of tower.Water is extracted into tower internal upper part from collecting-tank by water pump, then nebulizes through nozzle spray, and the water smoke of spray from top to bottom, is mixed with the waste gas rising, and reaches the function of waste gas humidification.
(3) biological purifier:
Waste gas imports biological purifier after humidification tower again, and the waste gas after humidification enters from the top of biological purifier, then discharges from bottom or side.Biological purifier can adopt rectangle structure, in biological purifier built with biologic packing material, biologic packing material has microorganism.Waste gas when by biologic packing material, the microorganism on biologic packing material can adsorb with degraded printing waste gas in volatile organic matter (voc) become co2And water.With the Organic substance in waste gas as nutrient, own growth is bred and metabolism for microorganism.Waste gas stops about 10-20 second in biological purifier.
The beneficial effect of present treatment technique is:
Present treatment technique adopts Biological fitler method, and the feature of present treatment technique is compared with other handling process:
1. treatment effeciency is high, the voc that can thoroughly degrade in waste gas, and has good deodorizing effect；
2. operating cost is low, easy to maintenance；
3. stable, biological cleaning process is the process of the own growth metabolism with the organic substance in waste gas as nutrient for the microorganism；Operation steady in a long-term, does not exist as activated carbon, and meeting adsorption saturation needs the problem of regeneration.
4. degrade thoroughly, non-secondary pollution, the pollutant in waste gas can thoroughly be degraded, purified gas odorless, tasteless.
5. long service life, the continuous self-reproduction of the microorganism in biological cleaning and metabolism, continuous autosynthesis are it is not necessary to change.
Brief description
Fig. 1 is process flow diagram.
Specific embodiment
, 1. by machine room's waste gas exhaust to humidification tower bottom, entrance humidification tower is 2. for blower fan；3. bottom has collecting-tank water tank, and 4. the water of collecting-tank be extracted into inside humidification tower top through water pump, then through spray nozzle 5. atomisation；Waste gas is mixed with water smoke phase after humidification tower bottom enters, and 3. water from top to bottom, then be back to collecting-tank water tank；And 7. 6. the outlet of the humidified top of tower of gas after humidifying be pumped to biological purifier；From the top of depurator through biologic packing material 8. gas, run from top to bottom, and 10. outward arrange again by the outlet through biological purifier bottom for waste gas after treatment；The moisture content that biological purifier doubts knot from gas focuses on the bottom of depurator again, then through outlet be 9. back to the collection water tank of humidification tower 3. after recycled.
