Abstract
The utility model discloses an absorption tower which comprises a tower body. Tower plates are arranged in the tower body; liquid collecting boxes are arranged between the tower plates; and heat exchangers are connected in the tower body. In the utility model, the number of the heat exchangers can be set according to the requirement of heat exchange in the tower body, and each tower plate can be provided with a heat exchanger; and under the mentioned circumstance, the heating exchanging area is increased, and the media passing through each layer of tower plate are effectively collected and then conduct heat exchange timely, therefore, the efficiency of heat exchange is greatly improved and the improvement of the absorption efficiency of the media is reliably guaranteed. Meanwhile, as the shell side, the tower body is provided with a telescopic slideway, and the heat exchanging pipe bundle adopts telescopic U-shaped pipe bundle, so that the operation and the maintenance are facilitated. Furthermore, the absorption tower can shorten process and reduce equipment investment.
Description
Technical field
The utility model relates to a kind of absorption tower, can be used for nitrogen oxide vent gas treatment in gold-extracted tail slag comprehensive utilization and the production of various nitric acid industry.
Background technology
At present, the absorption technique flow process complexity of nitrogen oxide tail gas needs 4 to 5 grades of absorption tower series connection usually, and every inter-stage needs circulating pump to carry out mass transport and adopts heat exchanger to carry out heat exchange, and occupation of land space and equipment investment are bigger.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provides direct heat transfer in a kind of material tower, a kind of absorption tower that can improve absorption efficiency and shortened process.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of absorption tower, it comprises tower body, is provided with column plate in described tower body, is provided with to receive the liquid case between the described column plate of adjacent setting, it is characterized in that: be connected with heat exchanger in described tower body.
Between described column plate, be provided with and receive the liquid case, in described tower body, be connected with heat exchanger.
Adopt absorption tower of the present utility model, require to be provided with the number of heat exchanger according to heat exchange in the tower, can heat exchanger all be set every layer of column plate, heat exchange area increases, in time carry out exchange heat after the medium effective collection of every layer of column plate of flowing through, improved heat exchanger effectiveness so greatly, for the absorption efficiency that improves medium provides reliable assurance.Simultaneously, tower body is as shell side, and setting can be taken out slideway, and heat-exchanging tube bundle adopts the U type pipe tube bank of drawable type, makes Operation and maintenance very convenient.And shortened technological process, reduced equipment investment.
Description of drawings
Fig. 1 is the front view on a kind of absorption tower of the present utility model;
Fig. 2 is the heat exchanger part section detail drawing on absorption tower shown in Figure 1 of the present utility model;
Fig. 3 is the VI schematic diagram of Fig. 2.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
A kind of absorption tower as Figure 1-3, it comprises the tower body 2 that is contained on the skirt 1, is provided with column plate 3 in described tower body, is provided with to receive liquid case 4 between described column plate, is connected with heat exchanger 5 in described tower body.The shell side of described heat exchanger 5 is the U type pipe tube bank that described tower body and heat-exchanging tube bundle adopt drawable type.
Preferably be externally connected with tube bundle support plate 6 in described U type pipe tube bank, described tube bundle support plate bottom is parallel is welded with two round steel slideways 7, parallelly on the base plate of receiving the liquid case be welded with two rail supported framves 8, described two round steel slideways are installed in respectively on described two rail supported framves.
This combined type absorption tower, it is the combination of column plate tower and heat exchanger, can establish 1 to 100 laminated board type tower tray in the tower, according to actual mass-and heat-transfer require every layer of column plate that heat exchanger all is set or which floor column plate is provided with a heat exchanger, heat exchange area is 1 square metre to 2000 square metres.The medium of every layer of column plate of flowing through effectively, in time carries out exchange heat, improves heat exchanger effectiveness, for the absorption efficiency that improves medium provides reliable assurance.
Simultaneously, tower body is as heat exchanger shell pass, and for ease of the heat-exchanging tube bundle Operation and Maintenance, heat-exchanging tube bundle adopts the U type pipe tube bank of drawable type, and two round steel slideways are installed in respectively on described two rail supported framves and can conveniently extract.
This tower can make technological process shorten, and has reduced equipment investment.
