2, NOx etc. emission gases recovery or reduce discharging object, can carry out different absorption reactions respectively with different absorption reaction liquid can the off-gas recovery purifying problem of disposable solution complexity.
Embodiment 1
As shown in Figure 1 and Figure 2, in the present embodiment, be disposed with the first order ~ fourth stage hypergravity reaction zone I, II, III, IV that gas passage is connected, become an entirety with horizontal housing 5 by Flange joint, compact conformation, small volume.Each hypergravity reaction zone I, II, III, IV is arranged in order by horizontal direction, gas passage as the path of A to B in Fig. 1, by the shell air inlet 51 be communicated with successively, each hypergravity reaction zone I, II, III, IV, housing gas outlet 52 forms.Flange joint is passed through between hypergravity reaction zone I, II, III, IV described in each.
Be provided with the rotating mechanism exchanged for generation of hypergravity and mass transfer in each hypergravity reaction zone I, II, III, IV, the rotating shaft 2 of this rotating mechanism is horizontally disposed with; The reactant liquor input mechanism 10,12,14,16 of each hypergravity reaction zone I, II, III, IV is independent separately, and the reactant liquor of input only carries out mass transfer exchange at the gas of this hypergravity reaction zone and process.Rotating mechanism is arranged in the gas passage of hypergravity reaction zone I, II, III, IV.The reactant liquor recovering mechanism 11,13,15,17 of each hypergravity reaction zone I, II, III, IV (be liquid collection opening at the present embodiment) is independent separately, thus is conducive to absorbing waste liquid and again recycles.
Rotating mechanism comprises rotating shaft 2 and is connected with rotating shaft 2 and the rotation filler 3 of synchronous axial system.Preferably as shown in Figure 3, as the present embodiment, rotating filler 3 adopts silk screen to rotate filler, be arranged in the form of a ring rotating shaft 2 peripheral and with its synchronous axial system, can first rotation filler 3 be fixed on a rotating disk 31 during installation, and then rotating disk 31 center and rotating shaft 2 are fixed, drive unitary rotation by rotating shaft 2.Rotating disk 31 is positioned at and rotates filler 3 near the side of shell air inlet 51.Rotating disk 3 diameter is at least not less than ring-type and rotates the internal diameter of filler 3, thus blocks the hollow region that flue gas directly rotates filler 3 by ring-type and enter next stage hypergravity reaction zone.Best, rotating disk 3 diameter is not less than the external diameter that ring-type rotates filler 3, as the present embodiment, owing to being stopped by rotating disk 31 after making flue gas enter hypergravity reaction zone, it can be forced to enter from the through hole rotating filler 3 outermost and to rotate filler 3 inside, to the flue gas rotating filler 3 central motion with from rotates in the middle part of filler 3 outside move be dispersed in after the reactant liquor rotating filler 3 interior surface carries out sufficient mass transfer exchange, then be expelled to the hollow region of the rotation filler 3 of ring-type from the through hole rotating filler 3 inner ring, then enter next stage hypergravity reaction zone.
For avoiding flue gas directly to enter next stage hypergravity reaction zone without rotation filler 3, preferably, the gap between rotation filler 3 and next stage hypergravity reaction zone is provided with seal 7.Preferred, the seal 7 adopts labyrinth seal.As the present embodiment, labyrinth seal is ring-type, comprises the two parts engaging each other and play sealing function, and wherein a part is fixed on and rotates filler 3 near the side of next stage hypergravity reaction zone, with rotation filler 3 synchronous axial system; The corresponding next stage hypergravity reaction zone that is fixed on of another part is near the side rotating filler 3.When carrying out purified treatment, the reactant liquor of ejection can penetrate in the gap of labyrinth seal, ensures sealing effectiveness further.
Reactant liquor input mechanism 10,12,14,16 is tubulose, is separated respective independence, comprises with rotating shaft: the supporting drainage part 161 vertically arranged; Rotate from supporting drainage part 161 top to ring-type the water emitting portion 162 that in the middle part of filler 3, hollow position extends, the tube wall of this water emitting portion 162 offers multiple hole for water spraying.Water emitting portion 162 can be one, also more than 2 can be arranged, be communicated with supporting drainage part 161 top by isocon 163, such as Fig. 3, water emitting portion 162 circumferentially evenly arranges 3, be communicated with supporting drainage part 161 top by the isocon 163 of one section of arc, now reactant liquor sprays more even.In the present embodiment, reactant liquor input mechanism 10,12,14,16 does not connect with rotating shaft 2, but carry out sprinkling reactant liquor independent of rotating shaft 2 side, therefore the rotating shaft of hypergravity reaction zone at different levels can be hollow or solid, in addition, can directly adopt a rotating shaft 2 simultaneously running through the integration of hypergravity reaction zone at different levels to form, rotating shaft simultaneously 2 and power shaft 8 also can be same axis, are therefore directly connected with motor 9 and link.Certainly, also rotating shaft 2 can be form by the rotating shaft of four sections short is affixed, is then connected with motor 9 by power shaft 8 again and links.
To adopt embodiment 1 equipment, treatment and purification method is conducted further description:
Flue gas is from shell air inlet 51 access arrangement, first order hypergravity reaction zone I reactant liquor such as water when rotating filler 3 and rotating is positioned at hollow position in the middle part of ring-type rotation filler 3 water emitting portion 162 from first order reactant liquor input mechanism 10 sprays, with flue gas reverse flow, hypergravity is produced at rotation filler 3, enhance reactant liquor to contact with dust, carry out adsorbing powder dust, thus reaching removing of dust, the reactant liquor being then adsorbed with dust under the influence of centrifugal force can be thrown on first order hypergravity reaction zone I inwall and collect in first order reactant liquor recovering mechanism 11, flue gas through removing dust directly enters second level hypergravity reaction zone II (completing in housing 5 inside), the absorbing liquid of the second level or reactant liquor such as adopt buck or limewash as a same reason, enter from second level reactant liquor input mechanism 12 and spray, with flue gas reverse flow, hypergravity is produced at rotation filler 3, enhance liquid and smoke contacts carries out adsorbing flue gas and reacting, thus reaching removing of sulfur dioxide, last absorbing liquid or reactant liquor are thrown under the influence of centrifugal force on inwall and collect in second level reactant liquor recovering mechanism 13, analogize therewith, flue gas enters into third level hypergravity reaction zone III from second level hypergravity reaction zone II, the third level such as utilizes ammoniacal liquor to make absorbing liquid or reactant liquor, enter from third level reactant liquor input mechanism 14 and spray, with flue gas reverse flow, hypergravity is produced at rotation filler 3, enhance liquid and smoke contacts carries out adsorbing flue gas and reacting, thus reaching removing of nitrogen oxide, absorbing liquid at this moment or reactant liquor are thrown under the influence of centrifugal force on inwall and collect in third level reactant liquor recovering mechanism 15, in order to increase one-level again to the purification of flue gas better and flue gas enters into fourth stage hypergravity reaction zone IV from third level hypergravity reaction zone III, the fourth stage such as utilizes makes absorbing liquid or reactant liquor with the ammoniacal liquor of third level variable concentrations, enter from fourth stage reactant liquor input mechanism 16 and spray, with flue gas reverse flow, hypergravity is produced at rotation filler 3, enhance liquid and smoke contacts carries out adsorbing flue gas and reacting, thus remove nitrogen oxide further, at this moment absorbing liquid or reactant liquor are thrown under the influence of centrifugal force on inwall and collect in fourth stage reactant liquor recovering mechanism 17, purified gas is discharged from B housing gas outlet 52.
