Description
Technical field
The invention belongs to waste gas pollution control and treatment technical field, be specifically related to a kind of adsorption filtration treating apparatus of organic exhaust gas.
Technical background
That organic exhaust gas generally all exists is inflammable and explosive, poisonous and harmful, water insoluble, be dissolved in organic solvent, feature that intractability is large.What when VOCs treatment, generally adopt is the multiple principles such as organic exhaust gas active-carbon adsorption treatment method, Production by Catalytic Combustion Process, catalytic oxidation, acid-base neutralization method, plasma method.At present China to the improvement of organic exhaust gas with the most use be exactly activated carbon and fixed bed absorption+catalytic-combustion processing system.This system is that active carbon is seated in fixed bed, then adsorbent bed and catalytic combustion system are combined into cleaning treatment system.
But this system exists a defect, the active carbon adopting is exactly made its regeneration desorption temperature of sorbing material and is generally all controlled at below 140 ℃, and such temperature is difficult to desorption for boiling point at more than 140 ℃ organic exhaust gas.And when charcoal absorption after this class gas, at 140 ℃, carry out above desorption charcoal layer to be easy to again glow; Secondly, active carbon desorption is actual to be discharged the VOCs being originally adsorbed in activated carbon capillary exactly again, does not reach the object of elimination.
Summary of the invention
The adsorption filtration treating apparatus that the object of this invention is to provide a kind of organic exhaust gas.
The adsorption filtration treating apparatus of organic exhaust gas, comprise adsorption filtration device, adsorption filtration device is containing sorbing material and filter assembly, filter assembly is combined into by the filtering cabin filter inner with it, filter appearance arranges filter membrane, filter membrane appearance is adhered to sorbing material, filtering cabin space outside filter membrane connects respectively feed arrangement, device for discharging and inlet duct by valve, filter inner chamber connects pure qi (oxygen) collecting pipe, the suction tube of feed arrangement connects loading hopper, device for discharging connects ash discharging hole, and pure qi (oxygen) collecting pipe connects pure qi (oxygen) delivery pipe.
The filter effect of obtaining in order to increase filter area, in filter assembly, can and show a plurality of filtering cabins, can be preferably with 2～6 filtering cabins, between each filtering cabin for up and down or left and right Rankine-Hugoniot relations, and with supporting connection of air inlet arranged side by side in air inlet duct, each filtering cabin is interior and show a plurality of filters, can be preferably with 2～20 filters.
In each filtering cabin, arrange upper and lower and/or arrange left and right >=2 rows' filters, filter number of each row is identical, in row, each filter is arranged side by side, corresponding filter inner chamber serial connection between upper and lower and/or left and right row.
In the present invention, filter membrane material is PTFE(polytetrafluoroethylene (PTFE)) or the composite material that contains PTFE; From consideration with low cost simple and easy to get, the outer PE(polyethylene of the preferred nexine PTFE+ of filter membrane material) composite material.When the most of particle diameter of sorbing material is 0.1～0.4mm, filter membrane material is preferably PTFE(polytetrafluoroethylene (PTFE)); When the most of particle diameter of sorbing material is 0.4～0.8mm, filter membrane material is preferably: nexine is that PTFE+ skin is PE(polyethylene).This filter membrane when intercepting sorbing material, also further filtration, purification waste gas.
In order to increase bond area and the stability of sorbing material, the filter membrane of filter and appearance thereof becomes the folding face (waveform) of upper and lower complications together.
Sorbing material can be selected as stronger materials of adsorption capacity such as brown coal, activated carbon char, zeolites, can use separately also and can mix use.Consider effect and use cost, it is best that sorbing material is selected brown coal.
Organic exhaust gas, through collecting laggard Gas inlet tube, enters adsorption filtration device, through adsorption filtration, processes, and the last exhaust outlet from adsorption filtration device pure qi (oxygen) delivery pipe gas out reaches discharge standard.Meanwhile, the active adsorbing material in adsorption filtration device constantly contacts waste gas, and adsorption concentration is more and more higher, and the sorbing material of the state that finally reaches capacity is discharged body, burning disposal.
The present invention adopts brown coal, activated carbon char and/or zeolite etc., as sorbing material, organic exhaust gas is carried out to adsorption filtration processing.But the present invention proves and adopts brown coal to have many-sided advantage.Brown coal have more micropore and larger specific area, and surface has a lot of hydroxyls, carboxyl isoreactivity group, can, by multiple gases Semi-polarity and nonpolar ion and Molecular Adsorption, secondly, by filtering tiny sorbing material filtering, discharge clean gas.When sorbing material reaches capacity after state, use compressed air vibration cleaning, make it to ash bucket, be transported to boiler room burning, make pernicious gas become CO
2and H
2o.When brown coal operating temperature≤50 ℃, its adsorption effect is better.The present invention uses the brown coal of any granularity of particle diameter in 0.1～0.8mm.Brown coal price is low, and operating cost is low, and advantages of good adsorption effect becomes water and CO after brown coal and waste gas burning
2, non-secondary pollution.The sorbing material of prior art adopts active carbon, and price is expensive, and regeneration technology is difficult to be controlled, and in desorption and regeneration process, waste gas out, can cause secondary pollution.
Adsorption filtration chamber structure is the key technology of adsorption filtration device.Wherein, filter area has determined the disposal ability of whole table apparatus.Filter area is determined according to production capacity and each filtering cabin size.Filtering cabin internal filter adopts the design of thin space drawer-like, in filtering cabin, setting is arranged above and below >=2 filters of arranging, each filter number of arranging is identical, and interior each filter of row is arranged side by side, and filter inner chamber corresponding between arranging is up and down connected in series.Like this, both can extend gas residence time, also be convenient to the dismounting of filter.In addition, the filter membrane of filter and appearance thereof becomes the folding face of upper and lower complications together, is beneficial to adhering to of sorbing material, and the sorbing material amount that it adheres to is determined according to production capacity and filter area.
In adsorption filtration treating apparatus, sorbing material is carried also very important.When sorbing material sprays action launching, close inlet duct, close device for discharging, open main air blower, by forming negative pressure at filter inner chamber, sorbing material is adsorbed on to filter outer surface.
Adsorption filtration treating apparatus of the present invention adsorbs work through after a while, when the pressure reduction at filter import and export place surpasses the numerical value of setting, sorbing material reaches capacity substantially, need to change sorbing material.Now, first close inlet duct, close the suction tube of device for discharging and sorbing material feed arrangement, adopt compressed air to carry out blowback clean, by be adsorbed on that filter filter membrane outer surface adheres to sorbing material shake off the bottom to filtering cabin, open device for discharging, sorbing material is delivered to ash discharging hole by conveying worm, pack sorbing material collecting bag into, then be transported to appointment place burning or do other and process, as being used as boiler oil.
The absorbing treatment device of organic exhaust gas of the present invention, rational in infrastructure, adsorption filtration area is large, purified treatment is effective.
