Abstract
The utility model discloses a flash tank comprising a tank body. The tank body is provided with a feed inlet, a discharge outlet and an emptying port. The feed inlet is formed in the middle of the tank body, and the alkali liquor outlet of the feed inlet is formed downwardly; at least two disc-container-shaped splitter plates are arranged below the alkali liquor outlet of the feed inlet, every two neighboring splitter plates are staggered in the height and circumferential directions, the splitter plates allow alkali liquor entering from the feed inlet to overflow from the splitter plates from top to bottom into an alkali liquor warehouse under the tank body. Preferably, the emptying port is provided with a filter, which is made of silk net materials, inside. The flash tank has the advantages that the flash tank is long in flashing time, good in flashing effect, and environmental pollution can be reduced or avoided.
Description
Technical field
The utility model relates to the alkali liquor concentration equipment, particularly a kind of flash tank for the alkali lye flash concentration in the sheet alkali manufacturing process of chlor-alkali.
Background technology
In production concentration is 99% flaky sodium hydrate process, high alkali liquid is concentrated into 97% concentration through evaporation concentrator after, carry out of short duration flash concentration in flash tank, the alkali lye after flash distillation directly enters alkali liquor allocator, cools off and makes solid base through solid base alkali machine processed again.The hydroxide flake process for producing sodium can be divided into and just extruding alkali and negative pressure goes out alkali, and it is just to extrude alkali technology that technology is sent out in flash vaporization, is just extruding alkali and refer to that alkali lye exports under certain positive pressure.Be used for just extruding the unlimited equipment of flash tank for communicating with atmosphere of alkali mode, need not heat during its flash distillation, high temperature alkaline solution takes full advantage of its pressure and forms flash distillation with atmospheric pressure reduction condition, makes the water evaporates in the alkali lye, raising concentration.Because its device structure is simple, and need not consume additional any heat energy, just can reach the purpose that improves concentration.Therefore, just extruding the alkali mode is widely adopted.Existing flash tank mainly comprises charging aperture, discharging opening and the evacuation port that is located on the evaporator body.Charging aperture and discharging opening all are arranged at the flash tank bottom, and alkali lye is just discharged rapidly from the discharging opening of bottom after the bottom access arrangement carries out flash distillation.Therefore, it exists flash-off time short, the deficiency that the flash distillation effect is not good enough.In addition, stop alkali lye from the liquid barrier of evacuation port ejection though existing flash tank also is provided with one in the middle of charging aperture and emptying, the steam that alkali lye produces in flash process can be taken the little molecule alkali of a part out of from evacuation port, cause environmental pollution.For this reason, require further improvement.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and the flash tank that a kind of flash-off time is long, flash distillation is effective is provided.This flash tank also can further reduce or avoid a part of little molecule alkali to be taken out of from evacuation port.
For achieving the above object, the present invention adopts following technical scheme.
A kind of flash tank comprises tank body, is provided with charging aperture, discharging opening and evacuation port at tank body, and described charging aperture is located at the tank body middle part, and the alkali lye of charging aperture goes out mouth down; The alkali lye outlet below of charging aperture is provided with at least two disk-shaped container-like flow distribution plates, adjacent flow distribution plate is in the short transverse of tank body and circumferentially be staggered and arrange, and flows into the alkali lye storehouse of tank body bottom a plurality of flow distribution plates are overflowed alkali lye that charging aperture enters successively by from top to bottom flow distribution plate after.
Adopt the present invention of aforementioned techniques scheme, because described charging aperture is located at the tank body middle part, the alkali lye Way out of charging aperture down, charging aperture below is provided with at least two and is the staggered flow distribution plate that arranges in the tank body short transverse, and flow distribution plate flows into the tank body bottom after alkali lye that charging aperture enters is overflowed by from top to bottom liquid dish successively.When 97% concentrated alkali lye is carried out flash distillation, alkali lye at first enters the flow distribution plate of the top in the tank body from charging aperture, rise to the overfall height of flow distribution plate when alkali lye after, alkali lye flows out from overfall, the alkali lye that overflows forms the waterfall type liquid film, enter next flow distribution plate then, until overflowing the alkali lye storehouse that enters the tank body bottom from bottom flow distribution plate.Thereby greatly having prolonged the time of alkali lye from charging aperture to the alkali lye storehouse is flash-off time, and therefore, the flash distillation effect of high alkali liquid can be greatly improved.
Optimized technical scheme is provided with filter in the described evacuation port.Filter can filter the steam of discharging from evacuation port, can effectively reduce or avoid little molecule alkali lye to discharge with steam, thereby reduces or avoid environment is polluted.Filter can adopt filtering material with hole or screen pack class material etc. to make, to satisfy principle comprehensive selection such as service condition temperature, resistance to acids and bases, service life and economy.
Further optimized technical scheme, described filter is made by web material.As adopt the nickel wire net, but it has stronger acid-proof alkaline, resistance to elevated temperatures.
The utility model beneficial effect compared with prior art is, flash-off time is long, and flash distillation is effective, and can reduce or avoid environmental pollution.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but therefore the utility model is not limited among the described scope of embodiments.
Referring to Fig. 1, a kind of flash tank comprises tank body 1, is provided with charging aperture 2, discharging opening 3 and evacuation port 4 at tank body 1, and described charging aperture 2 is located at tank body 1 middle part, and the alkali lye of charging aperture 2 goes out mouth down; The alkali lye outlet below of charging aperture 2 is provided with at least two disk-shaped container-like flow distribution plates 5, adjacent flow distribution plate 5 is in the short transverse of tank body 1 and circumferentially be staggered and arrange, and flows into the alkali lye storehouse of tank body 1 bottom a plurality of flow distribution plates 5 are overflowed alkali lye that charging aperture 2 enters successively by from top to bottom flow distribution plate 5 after.
Be provided with the filter of being made by the nickel wire net 6 in the described evacuation port 4.
Though more than combine accompanying drawing and described embodiment of the present utility model, but those of ordinary skill in the art can recognize also in the scope to claims and make various variations or modification that these modifications and variations are interpreted as within scope of the present utility model and intention.
