Abstract
The utility model relates to a waste gas treating and recycling device which is used for recovering and purifying waste gas through two deaeration towers which are connected in series, wherein zinc sulphate which is easily molten into water is quickly absorbed by the deaeration towers, and then extract in the waste gas is intercepted, and the participated water flows into an incineration pool again to be treated and refined. Meanwhile, discharged gas is relatively pure, air and environments are not polluted, and resources are further saved as rainwater is used.

Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 and Fig. 2: exhaust-gas treatment retracting device, for the waste gas of white vitriol preparation is recycled.This exhaust-gas treatment retracting device comprises deaeration tower 10, air exhauster 20, chimney 30.Concretely:
This deaeration tower 10 arranges and contour 2 for left and right.This deaeration tower 10 includes tank body 11.This tank body 11 comprise be positioned at these tank body 11 tops gas outlet 111, be positioned at these tank body 11 lower side concentrate steam inlet 112, be positioned at the water export 113 of these tank body 11 bottoms.Meanwhile, in this tank body 11, be provided with successively from bottom to up the first packing layer 12, the first spray head 13, the second packing layer 14, the second spray head 15, filter course 16.Wherein, after this first spray head 13 and this second spray head 15 are connected to water source, can spray water or water smoke.In the present embodiment, this first spray head 13 and the second spray head 15 are all connected with storage tank 40 by magnetic valve 17, and the height of the lowest part of this storage tank 40 is positioned at the top of these the second spray head 15 place height.Meanwhile, the top of this storage tank 40 is connected with the water receiving bucket 41 of upper opening, and this storage tank 40 connects underground water source by water pump 42.That is, can realize the water spray of this first spray head 13 and the second spray head 15, and take full advantage of rainwater by means of potential energy, only, in the time of this storage tank 40 interior lack of water, square tube is crossed this water pump 42 moisturizings.
Further say, the gas outlet 111 that is positioned at the deaeration tower 10 of left is communicated to this chimney 30 by this air exhauster 20, and these air exhauster 20 place height are positioned at the below of these concentrate steam inlet 112 place height.The gas outlet 111 that is positioned at right-hand deaeration tower 10 is communicated with the concentrate steam inlet 112 of the deaeration tower 10 that is positioned at left, and the concentrate steam inlet 112 that is positioned at right-hand deaeration tower 10 is communicated to exhaust gas source.These 2 water exports 113 are all connected to an ashing pond 50., 2 deaeration towers 10 are cascaded, first waste gas enter and be positioned at right-hand deaeration tower 10, through the first packing layer 12 in right-hand deaeration tower 10, the first spray head 13, the second packing layer 14, the second spray head 15, the filtration of filter course 16 and deposition are held back a part of extract, then waste gas enters the deaeration tower 10 that is positioned at left again, through the first packing layer 12 in the deaeration tower 10 of left, the first spray head 13, the second packing layer 14, the second spray head 15, the filtration of filter course 16 and deposition are held back more extract, make the processing degree of waste gas more thorough, do not need to take high height.
Further say, on these water receiving bucket 41 upper openings, be stamped orifice plate 43 prepared by plastic plate or corrosion resistant plate.Like this, be beneficial to interior the connect rainwater of this water receiving bucket 41 comparatively clean.
Continue to optimize, in this deaeration tower 10, be positioned at the water fender 18 that below is provided with and this concentrate steam inlet 112 matches of this first packing layer 12.This water fender 18 be away from one end of this concentrate steam inlet 112 under skewed, and this water fender 18 is for there being the corrosion resistant plate preparation of through hole.; waste gas in this concentrate steam inlet 112 enters this tank body 11 is liquid vapour mixture, and this liquid vapour mixture is subject to stopping of this water fender 18, and gas phase wherein can continue to rise; and liquid phase is directly attached on this water fender 18, finally flow to this water export 113.
Row is optimized again, and this first packing layer 12, the second packing layer 14 and filter course 16 are endways multilayer stainless steel cloth placed side by side.Not only effect is better for the first packing layer 12, the second packing layer 14 and filter course 16 like this, and very easily changes and keep in repair.Certainly, stainless steel cloth is positioned in certain gripper shoe.Such as, this gripper shoe is the corrosion resistant plate that has through hole or the plastic plate being fixed in this tank body 11.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
