Technical field
This utility model relates to tail gas disposal technique field, relates in particular to a kind of absorption tower.
Background technology
In commercial production, conventional Exhaust of alcoholysis Exhaust of alcoholysis to be installed absorption tower, is mainly used in the suction of Exhaust of alcoholysis
Receiving, this absorption tower is typically designed to sieve-plate tower, liquid is from tower top spray, directly carries out with upstream Exhaust of alcoholysis
Gas-to-liquid contact, in Exhaust of alcoholysis, the material such as methanol, methyl acetate is absorbed by liquid.But owing to absorption tower is simple sieve plate
Tower, Exhaust of alcoholysis flow velocity is also very fast, and heat exchanger time is short, causes and goes out liquid temp cooling range on absorption tower only at about 30 degree,
The material such as methanol, methyl acetate in tail gas can not be reached and all reclaim purpose, meanwhile, simple sieve-plate tower, it is impossible to remove very well
The PVA mist carried secretly in Exhaust of alcoholysis, thus cause absorption tower sieve plate hole plug；It is not easy to maintenance simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of absorption tower, to overcome current existing absorption tower to be simple sieve-plate tower,
Exhaust of alcoholysis flow velocity is fast, and heat exchanger time is short, and absorption tower temperature cooling range is only at about 30 degree, it is impossible to reduce alcoholysis tail
Vapor-liquid temperature and the purpose fully absorbed of the material such as methanol, methyl acetate, meanwhile, simple sieve-plate tower can not remove alcohol very well
Solve the PVA mist of flat rubber belting in tail gas, thus cause sieve-plate tower sieve pore blockade, be not easy to the present situation of maintenance simultaneously.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of absorption tower, including tower body, the top of described tower body is provided with gas outlet, and the bottom of described tower body is provided with liquid
Outlet, the top of described tower body is provided with fluid inlet, and the middle part of tower body is provided with circulation fluid inlet one, and the bottom of tower body is provided with
Circulation fluid inlet two, if described circulation fluid inlet two be arranged over dry liquids liquid trap, described liquid outlet
Being arranged over air inlet, if being provided with dried layer propping bar plate between described tower body internal liquid phase import and air inlet, described props up
The top holding screen is equipped with packing layer, and the top of described packing layer is equipped with hold-down grid, the propping bar of described top layer
Plate is provided with wire mesh demister.
Further, described fluid inlet, circulation fluid inlet one, the lower section of circulation fluid inlet two are equipped with liquid
Distributor.
Further, described support screen is 4 layers.
Further, from top to bottom every layer support the height of packing layer on screen and be respectively 600mm, 6000mm, 6000mm
And 4000mm.
Further, the top of described air inlet, fluid inlet, circulation fluid inlet one and circulation fluid inlet two is equal
It is provided with some access holes.
After using technique scheme, this utility model has following beneficial effect: be provided with in this utility model tower body
If being equipped with packing layer on dried layer propping bar plate, and every layer of support screen, packing layer can be passed through in absorption tower when absorbing
Slow down the velocity of liquid assets of industrial gases, make industrial gases and liquid be fully contacted greatly to be lowered the temperature assimilation effect, very
The good chemical industry material mist eliminated in industrial gases, it is ensured that the equipment operational excellence of next process；Top layer supports on screen
It is provided with demister, chemical industry material mist can be removed further；The unique design of access hole so that the maintenance on absorption tower and detection
More aspect is quick.
