Dividing plate of the present invention specifically refers to and inner barrel is divided into upper and lower two-part baffle arrangement, of the present invention specifically refer to up and down flue gas in processing procedure flue gas by lower from the path of movement, in the below of dividing plate, spray process is carried out to flue gas, further flue gas is filtered above individual dividing plate; Described wireway specifically refers to that flue gas is by the passage to top below dividing plate, described porous metals cylinder one end is set to blind end, the other end is provided with the beginning, the beginning of porous metals cylinder is connected with wireway, porous metals cylinder is for supporting the skeleton structure of filter membrane, the sidewall of porous metals cylinder is provided with for ventilative hole, and described filter membrane specifically refers to the sandwich adopting gas permeable material to make, the preferred macromolecule membrane of gas permeable material or cotton.
The course of work of the present invention: flue gas enters in closed shell by air inlet pipe, the spray liquid sprayed by atomizer below dividing plate carries out spray filtering, a part of pernicious gas in flue gas is by spray-absorption, and the sedimentation under the effect of spray liquid of a part of solid particle, particle and the spray liquid of sedimentation are discharged by liquid outlet, it is inner that flue gas after spray process enters into porous metals cylinder by wireway, because the porous metals cylinder other end is blind end, and sidewall is provided with ventilative hole, flue gas is spread by porous metals cylinder Inside To Outside, enter into filter membrane, by the internal layer of filter membrane to skin progressively diffusive filtration, secondary filter process is carried out by filter membrane internal oxidition calcium, calcium oxide further can not only absorb the acidic materials in flue gas, and calcium oxide can absorb the moisture in flue gas, thus the flue gas cleaning degree after being filtered further by filter membrane is high, then the flue gas through filter membrane process is discharged by escape pipe.
The present invention once filters by being provided with spray liquid, spray liquid absorbs the pernicious gas in flue gas and makes the solid particles sediment in flue gas, flue gas after spray liquid process is again through the secondary filter of filter membrane, sour gas in further absorption flue gas and solid particle, improve the treatment effect of flue gas.
The present invention, by arranging porous metals cylinder, at porous metals drum outer wall parcel filter membrane, makes filter membrane detachable and easy to operate, can change filter membrane in time when the filter effect of filter membrane is deteriorated or lost efficacy, avoid the filter membrane lost efficacy to affect the secondary filter effect of flue gas.
Further, escape pipe is provided with air-introduced machine.
The setting of air-introduced machine can accelerate the velocity of discharge processing rear flue gas, improves the filter efficiency of filter membrane, and then improves the whole treatment effeciency avoiding the boiler exhaust gas treating apparatus of contaminated environment.
Further, the inlet end of wireway is connected with funnel structure, and funnel structure increases gradually Zi with the internal diameter of wireway link to inlet end.
The flue gas that structure like this is convenient to below by dividing plate imports in wireway.
Further, spray liquid is two alkali lye of NaOH, soda lime configuration.
The setting of two alkali lye can improve the efficiency absorbing pernicious gas in flue gas, effectively carries out acid-base neutralization, avoids acidic materials to corrode equipment, improve the service life of equipment.
Further, silicon carbide filter bag is provided with in wireway.
Silicon carbide filter bag can absorb minute solid particles in flue gas.
Further, activated carbon filtration bag is provided with in escape pipe.
Activated carbon filtration bag can adsorb flue gas moderate stimulation smell.
Further, porous metals cylinder one end is set to blind end, and the other end is set to the beginning, and the sidewall of porous metals cylinder is provided with air-vent.
Further, filter membrane is sandwich, and calcium oxide is arranged in interlayer.
Further, two ends of filter membrane are provided with the magic strap or double buckle that cooperatively interact.
Two ends of described filter membrane specifically refer to that filter membrane wraps up the initiating terminal and terminal being, magic strap, double buckle are prior art, are convenient to parcel and the dismounting of filter membrane.
To sum up, the invention has the beneficial effects as follows:
1, the present invention once filters by being provided with spray liquid, spray liquid absorbs the pernicious gas in flue gas and makes the solid particles sediment in flue gas, flue gas after spray liquid process is again through the secondary filter of filter membrane, sour gas in further absorption flue gas and solid particle, improve the treatment effect of flue gas.
2, the present invention is by arranging porous metals cylinder, at porous metals drum outer wall parcel filter membrane, makes filter membrane detachable and easy to operate, can change filter membrane in time when the filter effect of filter membrane is deteriorated or lost efficacy, avoid the filter membrane lost efficacy to affect the secondary filter effect of flue gas.
