Description

A kind of aerosol and oxynitrides adsorbent equipment of biological particles barn

Technical field

The utility model belongs to flue-cured tobacco processing technology field, and in particular to a kind of aerosol of biological particles barn With oxynitrides adsorbent equipment.

Background technique

Development with China's economic technology and the raising to environmental requirement, the effective and reasonable utilization and Air-pollution From Combustion of the energy The emission control of object is just received more and more attention and is studied.Currently, bulk curing barn biomass grain forming fuel combustion machine It is widely used in the tobacco curing barn of various regions, and is influenced by method for flue-curing tobacco leaves, the biological particles for tobacco flue-curing Fuel is easy to produce a large amount of aerosols and oxynitrides in combustion.Aerosol (aerosol) is small by solid or liquid Particle disperses and is suspended in the colloidal dispersion system formed in gas medium, also known as gas diffuser system.Its dispersed phase is solid Or liquid fine particle, size are 0.001~100 μm, decentralized medium is gas.Liquid aersol is commonly referred to as mist, solid gas Colloidal sol is commonly referred to as fog dust.The nitric oxide (NO) and titanium dioxide that nitrogen oxides generates in combustion mainly from fuel Nitrogen (NO2).Oxynitrides, which has become, is only second to SO₂Atmosphere pollution will be to Chinese atmospheric environment if do not tightened control Cause serious pollution.Nitrogen oxides of the excessive emissions into atmosphere is smelly to the formation of acid rain and photochemical fog and the earth The destruction of oxygen layer has direct influence.

Have a small amount of aerosol processing equipment now, but good can not be answered on biological particles barn , and the existing generally existing processing capacity of aerosol processing unit is poor, low efficiency, choke situation are serious etc. many asks Topic.Research in relation to oxynitrides administering method is very much, and it is big to be roughly divided into catalysis method, liquid absorption method, absorption method three Class；But existing oxynitrides processing unit is not particularly suitable for but there is also many deficiencies for biological particles barn On.

For above situation, it is necessary to invent the aerosol and oxynitrides absorption dress of a kind of biological particles barn It sets.

Compared with prior art, the utility model has following technical effect that

1, the aerosol of the utility model and oxynitrides adsorbent equipment, for the practical feelings of biological particles barn Condition has the remarkable advantage that processing capacity is strong, treatment effeciency is high, is handled by the classification of multi-stage absorption plate, raw sheet is gone back in catalysis Redox reaction effectively realizes the quick clear of aerosol and oxynitrides in the hot wind that biological particles burning generates It removes, flue gas is clean directly to be discharged.

2, the utility model first passes through the aerosol that spiral board tentatively removes greater particle size, then by physical filtering plate into The filtering of one stepping promoting the circulation of qi colloidal sol；Then the aerosol compared with small particle is removed by electrostatic precipitation, simultaneously because flue gas The quantity of electric charge of aerosol is increased under the action of the spiral board most started, to enhance the efficiency of electrostatic precipitation；It is then logical Cross catalysis go back raw sheet, in the presence of a catalyst so that reducing agent reacted with the oxynitrides in air-flow generation it is harmless Nitrogen and water, to effectively remove most nitrogen oxides；Finally pass through chemisorption again for remaining aerosol and nitrogen oxidation Object absorption is closed, to realize the purification of flue gas.

3, the utility model by using different aperture of filter screen physical filtering plate, successively by aerosol in large grain size, middle grain Diameter aerosol, small particle aerosol are filtered respectively, to effectively improve filter efficiency, are shortened filtration time, are avoided simultaneously The case where blocking strainer being easy to appear in existing filtering, but also can be directed to according to the partial size situation of aerosol in flue gas Property selection increase certain partial size physical filtering plate number, further enhance filter effect.

4, the utility model can choose the multiple catalysis of placement and go back raw sheet, mention according to the content of oxynitrides in air-flow High treatment efficiency, while different chemisorption plates can also be flexibly selected, to realize the efficient absorption to nitrogen oxides.

5, the utility model increases the flexibility of processing by the method for card slot type grafting adsorption plate, easy to operate, can be with According to arbitrarily selecting one such or a variety of processing units to be filtered absorption the case where aerosol.

6, the chemisorption plate of the utility model is by setting adsorbent layer and catalyst layer, so that being absorbed into adsorbent A small amount of nitrogen oxides directly by catalyst treatment, to liberate adsorbent, further increase adsorption efficiency；And due to that will change Physical filtering plate is arranged in adsorption plate and catalysis is gone back behind raw sheet, so that containing only denier by the air-flow of chemisorption plate Aerosol and oxynitrides, avoid in the prior art due to adsorbent quickly adsorption saturation and cause treatment effect significantly The case where reduction.

7, the utility model can directly clear up adsorption plate by the setting of cleaning unit, using cleaning spray head It sprays cleaning liquid (preferably surfactant solution), so that the aerosol etc. on adsorption plate is cleaned liquid absorption and is discharged, letter It is single easy to operate；By the setting of sealing device, flue gas is avoided to be expelled directly out from the edge of adsorbent equipment, pollutes environment.

8, outlet mouth is arranged in the utility model, so that nitrogen oxides is enough molten with gas by the water energy that catalytic reduction reaction generates Glue cleaning liquid effectively excludes together, and dilutional hyponatremia aggregation is avoided to influence the burning of biological particles.
