Description

A kind of vertical demister
Technical field
The utility model belongs to a kind of demister of chemical field, specially a kind of vertical demister.
Background technology
In the discharge process of industrial processes and industrial waste gas, by gas -- it is an important technique that liquid, which carries out separation, Process.Mist in the gas phase will be carried secretly in many Product Process production operations or dust is separated, and can just make production Normally successfully carry out.The purposes or structure of existing demister can be divided into numerous species, as louver separator, gravity sink Drop type separator and whirlwind board separator.
Existing demister is mainly made up of fixing devices such as waveform blade, plate, card articles, in wet desulphurization, is absorbed Tower in the process of running, is also easy to produce " mist " that particle diameter is 10--60 microns, " mist " not only contains moisture, and it is also dissolved with sulfuric acid, sulphur Hydrochlorate, sulfur dioxide etc., while also result in the stained and heavy corrosion of blower fan, heat exchanger and flue, therefore, wet desulphurization work The requirement of demisting is proposed in skill to absorption equipment, cleaned gas wants demisting before absorption tower is left.
But existing separator is not high, and it is not readily separated the mist compared with small particle;Though single mesh mist eliminator In general mist can be so separated, but requires that mist cleans, air-flow velocity is smaller, and resistance drop is big, and service life is short, equipment investment Greatly.Therefore, study and produce the new and effective demisting that separative efficiency is high, resistance drop is small, allowable superficial gas velocity is big, choke preventing function is strong Device turns into the problem of in the urgent need to address in industrial production.
The content of the invention
The utility model, which is based on vertical demister in current tower, due to using defogging effect limited, to be influenceed environment and causes A kind of the problem of polluting air, there is provided vertical demister.The utility model carries out deeper technological improvement to existing apparatus, reaches ring Guaranteed request, increase economic efficiency, substantially increase demisting efficiency, mist can be free of after passing the gas through the present apparatus.
In order to realize the above object concrete technical scheme of the present utility model is:
A kind of vertical demister, including tower wall, porous folded plate, fixed plate, silk screen, baffle plate and guiding device, described silk Netcom crosses fixed plate and is fixed in demister, and silk screen be arranged in parallel with tower wall, and porous folded plate is set in the space that silk screen is built, Fixed plate and baffle plate are closely connected with tower wall, and demister is divided into upper and lower ends, and guiding device is set in the side of demister.
Described porous folded plate is N layers, such as 5 layers, porous folded plate can make the intercepted effect of the drop of size.Silk screen Effect is to intercept droplet and mist.
Described guiding device is delivery hole or catheter.
Demister in the utility model, when being flowed through to the gas containing mist with certain speed, due to the inertia of gas Effect of impact, mist collide with porous folded plate and silk screen and are attached in folding shape plate surface.Roll over mist in shape plate surface Diffusion, the gravitational settling of mist make mist form larger drop and with air-flow counter motion to folded plate and silk screen junction, by Make it that drop is increasing in steering centrifugal force and its with the surface tension of the rubbing action of folding shape plate, suction-operated and liquid, Until the drop gathered arrives greatly climbing power of its own the caused gravity more than gas and when making a concerted effort of surface tension of liquid, drop Just it is separated with silk screen water conservancy diversion.The combination filtering of the double-layer porous folded plate and silk screen of demister adds what mist was captured Chance, the mist not being removed are acted on and are captured in porous folded plate and silk screen next time again, such repeated action, so as to big Improve demisting efficiency greatly.
Compared with prior art, beneficial effects of the present invention are:
(One), fully and completely remove gas in poisonous and harmful substance, reach 99.% for more than 5 μm of drop demisting rate More than, to more than 8 ~ 40 μm of drop of diameter, demisting efficiency is up to 100%.
(Two), gas by porous folded plate and mesh mist eliminator after, separate these mists or dust substantially free of mist, Should separative efficiency it is high, resistance is small, is not easy to block, and also wants erection space small, and economical operation is securely and reliably, easy to operate.
Brief description of the drawings:
Fig. 1 is the structural representation of vertical demister described in the utility model;
Fig. 2 is the Section A-A structural representation of vertical demister described in the utility model;
Wherein, 1 --- --- --- --- silk screen, 5 --- baffle plate, 6 --- are led for fixed plate, 4 for porous folded plate, 3 for tower wall, 2 Flow device.
Embodiment
In order that present disclosure easily facilitates understanding, below in conjunction with the drawings and specific embodiments in the present invention It is further elaborated.But the scope that this should not be interpreted as to the above-mentioned theme of the present invention is only limitted to following embodiments.
Embodiment 1:
A kind of vertical demister, including tower wall, porous folded plate, fixed plate, silk screen, baffle plate and guiding device, described silk Netcom crosses fixed plate and is fixed in demister, and silk screen be arranged in parallel with tower wall, and porous folded plate is set in the space that silk screen is built, Fixed plate and baffle plate are closely connected with tower wall, and demister is divided into upper and lower ends, and guiding device is set in the side of demister. Described porous folded plate is N layers, such as 5 layers, porous folded plate can make the intercepted effect of the drop of size.The effect of silk screen is to block Cut droplet and mist.Described guiding device is delivery hole or catheter.
Fixed plate, baffle plate and the tower wall of demister are combined closely, and demister are bisected into two parts up and down, it has multistage Defrosting function:First, high-speed gas are online to the porous folded plate in demister lower end and side screw entrainment of liquid knockout, remove big Grain drop and solid particle;Then gas enters in demister through the porous folded plate in demister the latter half and side mesh media Chamber, again passes by porous folded plate and side mesh media removes remaining most little particle drops and solid particle;Finally Remaining drop and solid particle are removed, reaches complete demisting, the purpose of dedusting, drain mechanism is provided with also in demister side (delivery hole or catheter), reduce liquid holdup of the liquid in demisting medium under high gas velocity, it is therefore prevented that the reentrainment of liquid, folding Plate is porous plate, does not influence gas flow rate, reduces the resistance to air-flow, reaches antifogging, the effect of purification gas.
It is general more in tower top setting demister.The droplet that can effectively remove, so demister is mainly used in gas-liquid separation, also Can be that air cleaner separates for gas.When the gas with mist rises through silk screen and orifice plate with certain speed, because The inertia effect risen for mist, mist collide with silk screen orifice plate and are attached to filament orifice surface.With filament folded plate The scattered of mist, mist cohesion, gravitational settling on surface, make mist form larger drop and flow to edge along filament.Due to Filament can dampness, the surface tension of liquid and filament capillarity effect so that drop is increasing, until the liquid of set Drop arrives greatly climbing power and when the making a concerted effort of surface tension of liquid that the gravity that itself occurs surmounts gas, and drop is just shelled from filament From whereabouts.When the gas with mist through repeatedly trapping after substantially free of mist.
Although the utility model is elaborated by embodiment to it, this specialty is common Technical staff should be understood that the change for any form and details without departing from claims made on this basis Change, belong to the utility model scope of the claimed.
