Description
Technical field:
The utility model relates to chemical technology field, is a kind of circulating gas-liquid distribution equipment concretely, the gas-liquid-solid three-phase that is applicable to occur in the reactor or solution-air biphasic reaction.
Background technology:
At present, most gas-liquid-solid three-phase or solution-air biphasic reaction are all adopted in reactor and are occured, and reactor is in industry widely used with its several functions that is mixed with heating, evaporation, cooling and low high speed.In recent years, along with carrying out of industry energy conservation reduction of discharging and cleaner production activity, the upgrading of reactor accessory system function was also constantly strengthened.The gas-liquid-solid three-phase that in the past in reactor, carried out or solution-air biphasic reaction, exist gas skewness, gas-liquid-solid three-phase or solution-air two in liquid to contact unnecessary gas that insufficient, liquid phase discharges can not be recycling etc. problem.
At first, gas is skewness in liquid: directly performance is the zone that gas do not arrive that responds in the reaction liquid, and the bubble distribution rate is low, thereby the dead angle appears in gas-liquid-solid three-phase or solution-air two-phase system, causes reaction not exclusively, and reaction conversion ratio is low.Taking of having changes stir mode, improves mixing speed, attempt to reach and improve the purpose that gas phase distributes in liquid phase, thereby increased gas and energy resource consumption, and gas situation pockety in liquid is not improved yet.That have even the structure of stirring arm and reactor done larger change, the complexity of reactor is improved, thereby increased investment cost, and gas distribution effect in liquid is unsatisfactory.
Gas-liquid-solid three-phase or solution-air two contact insufficient: one of reason is that the reacting gas that enters liquid only is to pass into a pipe, air-flow is too concentrated, bubble is large, air-flow can not discharge by multi-point in liquid phase, two be that air velocity and mixing speed are too fast, gas time of staying in liquid phase is short, causes the solution-air two-phase complete reaction of failing, and portion gas overflows from liquid level.Gas-liquid-solid three-phase or solution-air two insufficient problem that contacts is the comparatively general problem of chemical industry always.
The unnecessary gas that liquid phase is discharged can not be recycling: the gas-liquid-solid three-phase that carries out in reactor or solution-air biphasic reaction, the liquid level superjacent air space always has the gas that the reaction do not participated in, these gases or emit, be absorbed processing, consequently: the discharging of pernicious gas has caused atmosphere pollution, and the gas resource does not obtain recycling.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned prior art to get not enough, and a kind of circulating gas-liquid distribution equipment is provided, mainly solve exist in the gas-liquid-solid three-phase that carries out in the existing reactor or the solution-air biphasic reaction gas skewness, gas-liquid-solid three-phase or solution-air two in liquid contact unnecessary gas insufficient, that liquid phase is discharged can not be recycling etc. problem.
In order to achieve the above object, the utility model is achieved in that a kind of circulating gas-liquid distribution equipment, it comprises ring pipe and gas-circulating system, its special character is to establish reacting gas inlet on the ring pipe and reacting gas portals, reacting gas inlet and air inlet pipe and gas-circulating system are connected, gas-circulating system is by the reacting gas fairlead, valve, asepwirator pump, valve, tail gas absorber and valve are interconnected to constitute, in this combination, ring pipe is immersed in liquid internal in the reactor, the reacting gas fairlead communicates with reactor, and ring pipe and gas-circulating system match and form circulating gas-liquid distribution equipment.
A kind of circulating gas-liquid distribution equipment of the present utility model, the gross area that its described gas portals are equivalent to 1 to 1.2 times of gas feed sectional area, and the diameter that gas portals is 2 millimeters; Described gas-circulating system can be delivered to reacting gas inlet to the unreacted gas of liquid superjacent air space in the reactor again; Described gas-circulating system is established the reacting gas fairlead; Described gas-circulating system is established tail gas absorber.
Equipment of the present utility model is compared with the prior art such as following table:
| Project | Existing reactor | Reactor behind configuration the utility model |
| The mass transfer characteristics | Gas-liquid mass transfer area is little | Gas-liquid mass transfer area is large |
