Abstract
The utility model discloses a large internal cooling type ammonia adsorption tower, comprising a tower ring, a bubble cap plate, a cooling water tank, a liquid distributor and a liquid re-distributor. An airlift pipe and a downcomer are arranged on the liquid distributor, and a gas inlet and an ammoniacal brine outlet are arranged on the bottom ring under the cooling water tank. The diameter of the downcomer arranged on the liquid distributor is from 50mm to 70mm, the bore diameter of the redistributor is from 100mm to 130mm, the pipe diameter of ammoniacal brine outlet is from DN250 to 350mm. Because of the changes of the diameter of the downcomer, the bore diameter of the redistributor and the pipe diameter of mmoniacal brine outlet, the bottom ring is kept at proper liquid level; thus the production capability of the tower is increased more than two times.
Description
Technical field
The utility model relates to a kind of efficient absorption equipment in the soda ash production process, and the utility model relates in particular to a kind of usefulness and remove the NH that the refined brine absorption of calcium, magnesium and salt slurry distills from system alkali filtrated stock
3And CO
2Gas, thereby the large-scale internal cooling type ammonia adsoption tower of the----ammonial brine that makes intermediate products.
Background technology
System alkali industry is inhaled ammonia equipment still based on the external-cooling type bubble column of gas-liquid counter current until early eighties both at home and abroad, i.e. refined brine segmentation in whole strokes absorbs, and segmentation exports to the outer cooling of tower and returns in the tower.Generally be divided into two sections or three sections, inhaling the ammonia sharing of load in each section, 2/3 suction ammonia amount is carried out at tower bottom, and is provided with circulation section in the bottom, absorbs temperature bottom reducing with qualified ammonial brine self circulation cooling and absorbs motive force to increase.In order to shift out a large amount of reaction heat and the heat of transformation, outside tower, to dispose the cooling device that adapts with uptake and be used for bottom ammonial brine circulation and the power-equipment of increase, pipeline is connected between tower and the cooling device back and forth, make absorption plant flow process complexity, floor space is big, troublesome poeration, the energy consumption height.
Since the eighties, prevailed both at home and abroad and carried out NH with cold ammonia absorption tower in novel
3And CO
2Absorption, cancellation tower outer cooling equipment.Interior cold tower obviously is better than the external cooling tower, but all variant on the project organization of cold tower both at home and abroad, on the production capacity of the present equipment of final body.State's interior diameter is that cold tower list tower abilities are general all at 700～850t/ about day in the φ 2800, and 600,000 tons of/year soda ash devices of a cover generally will dispose 3 φ 2800 ammonia absorption towers and just can meet the needs of production.
Summary of the invention
Can not only long-term operation after the purpose of this utility model is to provide a kind of equipment to go into operation, especially single tower production capacity improves 1 times, and the whole internal cooling type ammonia adsoption towers up to standard of operation index.
The utility model is achieved by the following technical programs.
Internal cooling type ammonia adsoption tower described in the utility model, it comprises tower circle, bubble cap plate, cooling water tank, liquid distribution trough, liquid re-distributor, described liquid distribution trough is provided with air-lift tube and downspout, have the outlet of gas vent and ammonial brine on the tower circle below the described cooling water tank, the downspout diameter that is provided with on the described liquid distribution trough is Φ 50-Φ 70mm, the redistributor aperture is Φ 100-Φ 130mm, and ammonial brine outlet caliber is DN250-350mm.
Because the downspout diameter that liquid distribution trough is provided with in the utility model, the aperture of redistributor, the change of ammonial brine outlet caliber makes the foundation ring keep suitable liquid level, thereby makes single output of column improve more than 1 times.
Description of drawings
Accompanying drawing is the utility model internal cooling type ammonia adsoption tower structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Internal cooling type ammonia adsoption tower of the present utility model is made up of casting tower circle 1, and top is washing section, and the tower circle is provided with bubble cap plate 2; The middle part is absorption, cooling section, its tower body is provided with cooling water tank 3, and have air inlet 4 and liquid outlet 5 on the foundation ring below cooling water tank 3, be provided with liquid distribution trough 6 at this section Ta Quan top, the middle part is provided with redistributor 7, described liquid distribution trough is provided with air-lift tube 8 and downspout 9, and ammonial brine storage tank 10 can be accepted in the tower bottom.The downspout diameter that is provided with on the described liquid distribution trough is Φ 50-Φ 70mm, and the redistributor aperture is Φ 100-Φ 130mm, and ammonial brine outlet caliber is DN250-350mm.The downspout diameter that is provided with on the described liquid distribution trough is preferably Φ 60-Φ 65mm, and the redistributor aperture is preferably Φ 115-Φ 125mm, and ammonial brine outlet caliber is preferably DN280-320mm.
Refined brine is entered through bubble cap plate by the washing section on top, the NH in washing, the absorption tail gas
3And CO
2, again by brine distribution device and salt solution redistributor evenly with the salt solution sprinkle in the middle of the cooling water tank that the middle part absorbs, cooling section is provided with, gas and liquid drive in the wrong direction, the outside wall surface of cooling water tank, heat transfer and mass transfer carry out simultaneously.
