Abstract
The utility model relates to a tail gas absorption technical field especially relates to an annular space absorption tower, include: from interior and outer nested interior tower, well tower and outer tower in proper order, compare with traditional multistage absorption equipment, the utility model discloses a nested a plurality of towers utilize a plurality of shower to handle waste gas, have effectively improved the treatment effeciency, compact structure is reasonable, and equipment takes up an area of for a short time, invests for a short time, and is supporting simple, and waste gas flows through the annular space between the absorption tower, has great area of passage in the annular space, and the passageway is narrower, need not to use gas distributor can realize gaseous evenly distributed.
Description
Technical field
The utility model is related to technology for absorbing tail gas field more particularly to a kind of annular space absorption towers.
Background technology
It is often used circulating absorption tower processing exhaust gas in chemical industry, in order to reinforce assimilation effect, multistage absorption can be used,
Exhaust gas is repeatedly handled, but multistage absorption equipment investment is big, occupied space is big, and gas phase pipe is needed between multiple absorption towers
Road connects, and engineering is more complex.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of structure conjunction
It manages, take up little area and the annular space absorption tower of small investment.
The utility model is to be achieved by the following technical programs：
A kind of annular space absorption tower, which is characterized in that including：From-inner-to-outer nested Nei Ta, Zhong Ta and outer tower successively,
The interior top of tower is provided with interior tower venthole, and interior tower bottom is connected with the interior tower drain across Zhong Ta and outer tower bottom
Pipe, interior tower side wall hypomere are connected with the air inlet pipe across Zhong Ta and outer tower side wall, and interior tower epimere is connected with across Zhong Ta and outer tower
The interior tower spray tube of side wall,
The middle tower bottom side wall is provided with middle tower venthole,
The outer top of tower is provided with outer tower venthole, and the upper ends Wai Ta are connected with outer tower spray tube, the connection of outer bottom of tower end side wall
There is outer tower drain pipe.
The utility model has the beneficial effects that：
Compared with traditional multistage absorption equipment, the utility model utilizes multiple spray tubes pair by nested multiple towers
Exhaust gas is handled, and treatment effeciency is effectively increased, and compact-sized rationally equipment takes up little area, and investment is small, mating simple, exhaust gas
Through the annular space flowing between absorption tower, there is larger aisle spare in annular space, and channel is relatively narrow, without using gas distributor
Being uniformly distributed for gas can be realized.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model.
In figure：Tower in 1., tower in 2., 3. outer towers, tower venthole in 4., tower drain pipe in 5., 6. air inlet pipe, tower spray in 7.
Shower pipe, tower venthole in 8., 9. outer tower ventholes, 10. outer tower spray tubes, 11. outer tower drain pipes.
Specific implementation mode
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings
The utility model is described in further detail with most preferred embodiment.
As shown, the utility model includes：From-inner-to-outer nested interior tower 1, middle tower 2 and outer tower 3 successively,
The interior top of tower is provided with interior tower venthole 4, and interior tower bottom is connected with to be arranged across the interior tower of Zhong Ta and outer tower bottom
Liquid pipe 5, interior tower side wall hypomere are connected with the air inlet pipe 6 across Zhong Ta and outer tower side wall, interior tower epimere be connected with across middle tower and
The interior tower spray tube 7 of outer tower side wall,
The middle tower bottom side wall is provided with middle tower venthole 8,
The outer top of tower is provided with outer tower venthole 9, and the upper ends Wai Ta are connected with outer tower spray tube 10, and outer bottom of tower end side wall connects
It is connected to outer tower drain pipe 11.
This absorption tower is compact-sized, and rationally equipment takes up little area, and investment is small, mating simple, by multiple spray tubes to exhaust gas
It is handled, effectively increases treatment effeciency and treatment effect, there are the rings flowed for exhaust gas between Nei Ta, Zhong Ta and outer tower
Gap, annular space is interior to have larger aisle spare, and channel is relatively narrow, and uniformly dividing for gas can be realized without using gas distributor
Cloth.
Embodiment 1
Exhaust gas enters Nei Ta from air inlet pipe and rises, and carries out first time spray process by interior tower spray tube, gas is from interior
Tower in entering in tower venthole, the waste liquid handled for the first time are discharged from interior tower drainage hole, and the gas in middle tower is under gas pressure
Enter outer tower from the middle tower venthole of bottom and rise, second of spray process, second of processing are carried out by outer tower spray tube
Gas afterwards is discharged from outer tower venthole, and the waste liquid of processing is discharged from outer tower drain pipe, and cocurrent is partly used in the present embodiment
Operation, pressure drop are smaller.
Embodiment 2
Exhaust gas enters outer tower from outer tower venthole and flows downward, and first time spray process is carried out by outer tower spray tube,
Treated, and other from tower in the entrance of middle tower venthole and rise, and the waste liquid of processing is discharged from outer tower drain pipe for the first time, middle tower
Interior gas enters Nei Ta through interior tower venthole and moves downward, and the gas into interior tower carries out secondary spray by interior tower spray tube
Leaching is handled, and treated, and gas is discharged through air inlet pipe, and the waste liquid after after-treatment is discharged through interior tower drain pipe, complete in the present embodiment
Portion is cocurrent cooling operation.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
