Wherein 1 represent cyclone dust collector, 1A represents spiral case case and separation chamber, and 1B represents air inlet, 1C represents conical sedimentation storehouse, and 1D represents the sedimentation mouth, and 2 represent moisture trap, 2A represents inner tube wall, and 2B represents the backwater cover, and 2B1 represents backwater cover irrigating gate, 2C represents water fender, 2D represents backwater hole, and 2E represents the water conservancy diversion helical blade, and 2F represents permeable hole, 3 represent air-vent, 4 represent water sealed tank, and 5 represent the sulphur removal reactor, and 5A represents tank body, 5B represents the sedimentation scavenge port, 5C is a control valve, and 5D is an air inlet, and 5E is a wind channel, 5F is a spray head, and 5G is an air-vent.
The design's key is and will adds the efficient gas and water separator of a cover in the dust arrester after the desulfurization as can be seen from accompanying drawing.It is the moisture trap 2 of drum, in this design, taked a compound shell mechanism with the cyclone dust collectors 1 compound moisture trap 2 that is in series, be that cylindrical inner tube wall 2A and sandwich-type backwater cover 2B forms a compound shell, inner tube wall 2A is provided with the water fender 2C that becomes 25-35 ° of angle with wall, its effect is to prolong the emission path of air-flow at inner core, strengthened the collision opportunity of residual water droplet and water fender 2C, and easily form to adhere to and be condensed into that big flood drips and flow down along water fender 2C ramp, be provided with backwater hole 2D at water fender 2C and inner tube wall junction, can move the water to flow into backwater cover 2B and discharge through irrigating gate 2B1.
Except that the design of water fender 2C, in inner tube wall, can also be provided with water conservancy diversion helical blade 2E.It is arranged among the air channel, makes air communication cross its back and produces the eddy flow attitude, and the centrifugal force that produces by rotation makes the water in the air-flow be attached to inner tube wall 2A.At this moment, on the top inner tube wall 2A with water conservancy diversion helical blade 2E uniform permeable hole 2F is set, the water that then gets rid of to inner tube wall 2A just flows into backwater cover 2B discharge through this permeable hole 2F.
More than two kinds of devices when strengthening aqueous vapor and separating, effectively the water of separating is discharged through backwater cover 2B again, hit atomizing once more during the air-flow of having avoided rising at a high speed with inner tube wall 2A forms, thereby improve the ability and the effect of the design's gas-water separation greatly.
More than two kinds of structures can be applied to separately among the design of moisture trap, also can combine and mix use.For example shown in Figure 1, be 25-35 ° water fender 2C and corresponding backwater hole 2D in setting of the lower end of inner tube wall 2A and wall.And be provided with water conservancy diversion helical blade 2E and supporting permeable hole 2F in the middle-end of inner tube wall 2A.The duplex test effect is preferable like this.
This device can match with any wet type desulfurizing dust-removing technology, and Fig. 2 has then provided the embodiment of a wet desulfurizer that matches.Desulphurization reaction still 5 among this embodiment can directly dock with the design and form a complete desulfation dust-extraction device, and this device is a kind of pot type desulphurization reaction still as can be seen from accompanying drawing 2.The main body 5A of reactor is drum jar shape, and the lower end is an ellipsoidal head, is provided with reactant scavenge port 5B and control valve 5C, and the discharge pipe straight cutting is gone in the water sealed tank 4.Tank deck is coniform contraction and forms air inlet 5D, is provided with the spray head 5F that sprays chemical reagent in air intake passage 5E.Air-vent 5G is located at the reactor middle part and can directly be communicated with the air inlet of dehydration deduster.
