Description
Technical field
The invention belongs to field of environment engineering, particularly a kind of improvement of flue gas desulfurization device.
Background technology
The dense-phase tower flue gas desulfurization technique is a kind of semi-dry method flue gas desulfurization technique, has that flow process is simple, floor space is little, the desulfurizing agent water capacity is low, does not lump, sticking wall, do not stop up, do not have burn into and do not have advantages such as waste water generation, desulfuration efficiency and sorbent utilization height, byproduct can fully utilize.
Original dense flow absorber semidry process desulfurization reactor is square tower body, flue gas enters from reactor top, in dense flow absorber under the stirring action of chain-type agitator, the desulfurizing agent that adds is fluidized state and contacts with flue gas, have an effect, reclaim desulfurizing agent through the sack cleaner circulation then,, guarantee desulfurized effect with utilization rate that improves desulfurizing agent and the time of contact that prolongs desulfurizing agent and flue gas.
Mainly there is following problem in equipment before improving:
1, equipment energy consumption height;
2, the cylindrical reactor inner air is mobile very unreasonable;
3, cylindrical reactor row is big to the dust concentration load of deduster;
4, shaft is bigger, processing and fabricating cost height, and easily cause vibration.
Summary of the invention
The objective of the invention is in order to solve original dense-phase tower desulfurizing equipment in actual moving process, because the problem on the structural design, generation loaded down with trivial details such as complex structure, construction and manufacturing procedure, power consumption is high, vibration obviously, go out problems such as the tower dust concentration is big.
A kind of circular dense phase fluidizing desulfurization apparatus, it is characterized in that desulphurization plant comprises square Wen's cloth tube 1, agitating device 2, elevator 3, guiding device 4, web plate 5, aggregate bin 6, humidifier 7, reaction zone 8 and distributing device 9, guiding device 4 is made up of material feeding hole 10, deflector skeleton 11 and deflector 12.Establish square Wen's cloth tube 1 before the cylindrical reactor tower body inlet, flue gas fully contacts with the equally distributed desulfurizing agent material of process agitating device 2 fragmentations, enters the cylindrical reactor tower body.Flue gas flows from bottom to top in cylindrical reactor inside, and the deflector 12 by cylindrical reactor inside enters reaction zone 8 and carries out desulphurization reaction, and flue gas is discharged from the outlet that is located at cylindrical reactor top after desulfurization.When flue gas passes through cylindrical reactor inside, run into the obstruction and the collision of web plate 5, part cloud is separated from flue gas, the material feeding hole that sees through guiding device falls into aggregate bin 6, behind humidifier 7 humidifications, transport back in the smoke inlet place distributing device 9 recycling by elevator 3.
Main feature of the present invention is: reactor is cylindrical, tower body diameter 1～12m, tower height 5～60m; Flue gas earlier through Wen's cloth system with after desulfurizing agent fully contacts, enter cylindrical reactor from bottom to top, the cross section of Wen's cloth tube is square, its length of side 500～1000mm, the chain rotating speed of stirring system is 50～1000 rev/mins, chain stripe pitch 10～500mm, diameter chain 1～30mm; The inner deflector of cylindrical reactor adopts the fish scale structural design, wide 10～1000mm, long 500～15000mm, 5 °～90 ° at inclination angle; Cylindrical reactor adopts ciculation fluidized technology to combine with close technology mutually, and the inner desulfurizing agent material concentration of cylindrical reactor is at 100～800g/m
3Between; 1～3 layer of web plate filter set up in cylindrical reactor inside, web plate mesh width 0.01～1m, can the row of making to the cloud concentration of deduster by original 600g/m
3Be reduced to 300g/m
3Below; Humidifier is loaded on the cylindrical reactor bottom.
Major advantage of the present invention is:
1, utilize ciculation fluidized technology and dense-phase tower technology to combine.Use the inside reactor desulfurizing agent material concentration of ciculation fluidized technology to be 100g/m merely
3Below, use the inside reactor desulfurizing agent material concentration 600～800g/m of dense flow absorber technology merely
3, two kinds of technology in conjunction with post-reactor inside desulfurizing agent material concentration at 100～800g/m
3Between, help the abundant reaction of desulfurizing agent and flue gas, improve the utilization ratio of desulfurizing agent simultaneously;
2, humidifier is loaded on the cylindrical reactor bottom.Reduce desulfurizing agent material shipping height, save energy consumption;
3, stir distribution device and put the reactor outside, ad hoc system is square Wen's cloth system, plays the effect of the stirring of desulfurizing agent material, cloth and reuse.Utilize venturi principle, the state that makes the desulfurizing agent material enter tower body is the atomizing shape, agitating device is positioned over the cylindrical reactor outside, shaft size after the improvement is reduced, be convenient to processing and installation, avoided simultaneously because shaft is installed in the vibration problems in the running that causes on the reactor;
4, set up the web plate filter in cylindrical reactor inside.Fluidized reaction carries out in cylindrical reactor, can stop part cloud by web plate, reduces the burden of deduster, can reclaim desulfurizing agent simultaneously, and the hole that makes it to fall into deflector recycles;
5, add deflector in the cylindrical reactor bottom.Because its special structure makes that not only can enter cylindrical reactor to flue gas plays guide functions, guarantees simultaneously can be fallen into collection bucket, recycle and reuse by the desulfurizing agent material under the web plate obstruct.

The specific embodiment
As shown in Figure 1, reactor is cylindrical tower body, and flue gas enters inside reactor from bottom to top and carries out desulphurization reaction.The gas approach place establishes square Wen's cloth system (being made up of square Wen's cloth tube, agitating device and distributing device), and agitating device fully disperses the desulfurizing agent material, makes it to mix with flue gas equably, enters cylindrical reactor inside together.Behind the deflector water conservancy diversion, desulfurizing agent material and flue gas are at inside reactor generation desulphurization reaction, and the state of inside reactor desulfurizing agent material and flue gas has guaranteed fully carrying out of desulphurization reaction between ciculation fluidized and close phase two states.Inside reactor is established the web plate filter, and holding back material feeding hole that partial desulfurization agent material makes it to see through guiding device, to fall into aggregate bin recycling, and the web plate filter has guaranteed that also row descends to the cloud concentration of deduster, alleviates the burden of deduster simultaneously.Flue gas drains into deduster by the top outlet behind desulphurization reaction.
As shown in Figure 2, guiding device is made up of deflector skeleton, deflector and material feeding hole.Deflector adopts the design of fish scale type, tilts to be dislocatedly distributed on the deflector skeleton, and the flue gas that enters reaction zone is played guide functions.Stopped the desulfurizing agent material that settles down by web plate and can fall into aggregate bin by material feeding hole.
As shown in Figure 3, square Wen's cloth system is made up of square Wen's cloth tube, agitating device and distributing device.The desulfurizing agent material is scattered in the stirring system through distributing device, after stirring by the abundant mixing of stirring chain, by square Wen's cloth tube input reaction zone.According to venturi principle, because the reducing effect of Venturi tube and cylindrical reactor, desulfurizing agent material and flue gas will enter cylindrical reactor inside in the mode of approximate winding-up, make the mixing of desulfurizing agent material and flue gas disperse exposure level to be strengthened, and ensure that desulphurization reaction fully carries out.
