Description
Technical field
The utility model relates to formaldehyde production equipment more particularly to a kind of absorption towers for adapting to high-concentration formaldehyde and absorbing.
Background technique
Formaldehyde absorbing tower is the equipment for absorbing formaldehyde gas, and traditional formaldehyde absorbing tower absorption is not thorough, formalin concentration
Low, the formalin if necessary to high concentration needs multiple towers to absorb, and equipment investment is big, takes up a large area.
Utility model content
The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of absorption that adaptation high-concentration formaldehyde absorbs
Tower.
Technical solution used by the utility model is as follows:
A kind of absorption tower for adapting to high-concentration formaldehyde and absorbing, including upper tower body and lower tower body, the lower tower body side setting
Formaldehyde gas import, lower end are arranged highly concentrated formaldehyde solution and export, and several column plates are arranged on lower tower body, float valve, weir is arranged on column plate
Plate and deflector, lower tower body are located at the top column plate side setting water supply pipe, the upper tower body and lower tower body by inclination every
Plate separates, and air inlet pipe and overflow pipe is arranged on tilt clapboard, it is molten that upper tower body is located at setting low concentration formaldehyde at tilt clapboard low spot
Liquid outlet, upper tower body is interior to be arranged packing layer, and upper tower body, which is located above packing layer, is arranged formalin spray tube, upper tower body the top
Waste gas outlet is set.
As a further improvement of the above technical scheme:
Formalin spray is also provided on position in the lower tower body between the lowermost column plate and formaldehyde gas import
Shower pipe.
Tilt clapboard is located at setting cloth gas hood in air inlet pipe.
The beneficial effects of the utility model are as follows: the absorption tower for adapting to high-concentration formaldehyde and absorbing, formaldehyde gas are introduced into
Lower tower body is provided with water layer on column plate, and formaldehyde gas breaks through the float valve of column plate, absorbs formaldehyde gas by water layer and forms formalin,
Unabsorbed formaldehyde gas enters upper tower body, then further absorbs formaldehyde gas by formalin in upper tower body, forms low concentration
Formalin, this low concentration formaldehyde solution can directly be discharged from low concentration formaldehyde taphole and collect, and can also be returned by overflow pipe
It flow in lower tower body, flows on the column plate of lower tower body, continue to absorb formaldehyde gas, the formalin of high concentration can be formed, from highly concentrated
It spends formalin outlet discharge to collect, formaldehyde gas, and i.e. exportable low concentration formaldehyde solution is fully absorbed by an absorption tower
Also exportable highly concentrated formaldehyde solution, a tower is multi-purpose, and equipment takes up little area.

Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment
As shown in Figure 1, the absorption tower for adapting to high-concentration formaldehyde and absorbing of the present embodiment, including upper tower body 1 and lower tower body 2,
Formaldehyde gas import 3 is arranged in lower 2 side of tower body, and lower end is arranged highly concentrated formaldehyde solution and exports 4, and several column plates are arranged on lower tower body 2
21, float valve, weir plate 211 and deflector 212 are set on column plate 21, and lower tower body 2 is located at 21 side of the top column plate and moisturizing is arranged
Pipe 22, upper tower body 1 and lower tower body 2 are separated by tilt clapboard 5, and air inlet pipe and overflow pipe 51, air inlet pipe are arranged on tilt clapboard 5
Upper setting gas distribution pipe 52, upper tower body 1 are located at setting low concentration formaldehyde taphole 6 at 5 low spot of tilt clapboard, set in upper tower body 1
Packing layer 11 is set, upper tower body 1 is and formalin spray tube 7 is arranged above packing layer 11, and upper 1 the top of tower body setting exhaust gas goes out
Mouth 8, lower tower body 2 are also provided with formalin spray tube on the interior position between the lowermost column plate 21 and formaldehyde gas import 3
7。
It is described to adapt to absorption tower that high-concentration formaldehyde absorbs in use, formaldehyde gas is sent into lower tower body 2 from formaldehyde gas import 3,
Formaldehyde gas is delivered up, while opening moisturizing in the downward tower body 2 of water supply pipe 22, and water flows on column plate 21, by weir plate 211 in tower
Water layer is formed on plate 21, formaldehyde pneumatic jack opens the float valve on column plate 21, and the water layer on column plate 21 absorbs formaldehyde by water layer
Gas forms formalin, with formalin is sprayed in the downward tower body 2 of formalin spray tube 7 in tower body 2 at present, guarantees first
The temperature of aldehyde gas prevents formaldehyde gas from polymerizeing in lower tower body 2, unabsorbed formaldehyde gas by 5 intake pipe 52 of tilt clapboard into
Enter upper tower body 1, and by arranging that cover is uniformly distributed formaldehyde gas, formaldehyde gas enters packing layer 11, while the formaldehyde of upper tower body 1 is molten
Liquid spray tube 7 sprays formalin, likewise enters packing layer 11, and it is molten that formaldehyde gas formation low concentration formaldehyde is absorbed in packing layer 11
Liquid, remaining exhaust gas is discharged from waste gas outlet 8 after absorption, while formalin can guarantee the temperature of formaldehyde gas, prevent formaldehyde gas
It polymerize in packing layer 11, the low concentration formaldehyde solution for absorbing formation can flow downwardly on tilt clapboard 5, and can be directly by low
6 discharge of concentration formalin outlet is collected or low concentration formaldehyde solution is back in lower tower body 2 by overflow pipe 51, cocurrent
Onto the column plate 21 of lower tower body 2, low concentration formaldehyde solution layer is formed, continues to absorb formaldehyde gas, forms highly concentrated formaldehyde solution, it is high
Concentration formalin can export 4 discharges from highly concentrated formaldehyde solution and collect.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
