Abstract
The utility model relates to chemical extraction equipment, in particular to a liquid dynamic sealing device of a mixer-settler. The device comprises a baffle of a mixing chamber and a light phase weir, wherein the light phase weir is higher than the baffle of the mixing chamber. Because the light phase weir is higher than the baffle of the mixing chamber, when combustible and explosive liquid is adopted as heavy phase, a non-combustible and unexplosive light phase liquid layer can be formed at the upper part of the combustible and explosive mixed phase, the combustible and explosive liquid is not contained in the liquid layer, and therefore the combustible and explosive mixed phase is stably sealed. Multiple experiments and formed products prove that the combustible and explosive mixed phase in the mixing chamber only flows horizontally from left to right, but does not flows upward any more, the combustible and explosive mixed phase in the mixing chamber can not be mixed into the non-combustible and unexplosive light phase layer, therefore the non-combustible and unexplosive light phase layer plays the sealing function, the mechanical seal of the rotating axle required to be used in the prior art is eliminated, the structure is simple, the security and the reliability are strengthened, and the operation cost is reduced.
Description
Technical field:
The utility model relates to chemical industry separation equipment, particularly extraction equipment.
Background technology:
Extraction is the conventional liquid liquid separating method of chemical industry, unit operations extraction equipment mixer-settler at chemical industry, the mixing of mixing chamber is mutually to upwards flowing down, cross the mixing chamber plate washer and flow into the clarifying chamber, be layered as heavy phase and light also mobile from left to right mutually mutually in clarifying chamber's mixing, two-phase is carried out hybrid extraction and can be aspirated the weight two-phase liquid of adjacent two-stage clarifying chamber under the effect of mixing chamber paddle, and then realizes continuous countercurrent extraction.The heavy phase weir of clarifying chamber and the height of light phase weir are controlled and have been regulated two-phase interface, avoid two-phase to carry secretly mutually, and the height of mixing chamber plate washer and light phase weir is generally by the contour conventional design that is designed to as shown in Figure 1.As extract with the two-phase heavy phase with gently for non-flammable and combustible liquids dynamic sealing device can be set on every grade paddle axle then mutually, if flammable and combustible liquids, the surface of mixing phase has volatile inflammable-explosive gas, therefore for safety, solve the movable sealing problem of rotating paddle with mechanical dynamic seal, volatilization gas is not leaked, but the periodic maintenance of mechanical seal need easy to wear, the use cost height, and security has much room for improvement.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, a kind of liquid dynamic sealing device of mixer-settler is provided, in heavy phase is inflammable and explosive liquid and gently mutually for non-when firing liquid, fluid-tight with light phase replaces mechanical seal, good sealing effect, simple and safe operation has been omitted mechanical seal and regular maintenance thereof.
The technical scheme that the utility model is adopted for achieving the above object is: the liquid dynamic sealing device of mixer-settler relates to mixing chamber plate washer and light phase weir, light phase weir aspect ratio mixing chamber plate washer height height.
The high 100-1000 millimeter of described light phase weir aspect ratio mixing chamber plate washer height.
The high 200-500 millimeter of described light phase weir aspect ratio mixing chamber plate washer height.
The utility model light phase weir aspect ratio mixing chamber plate washer height height, therefore be applied in the flammable and combustible liquids phase time of attaching most importance to, what can form the 100-1000 millimeter on the top of inflammable and explosive mixing phase non-ly fires light phase liquid layer, this liquid layer does not contain flammable and combustible liquids, thereby has stably sealed inflammable and explosive mixing phase.Prove through test of many times and shaped article, the inflammable and explosive mixing of mixing chamber is bottom horizontal flow sheet from left to right only mutually, will never upwards flow, the inflammable and explosive mixing of mixing chamber can not sneaked into non-inflammable and explosive light phase layer mutually, therefore non-inflammable and explosive light phase layer has played sealing function, saves the mechanical seal of the rotating shaft that prior art must use, and is simple in structure, and security reliability strengthens, and reduces use cost.
Description of drawings:
Fig. 1 is existing mixer-settler structural representation.
Fig. 2 is a level Four mixer-settler structural representation.
Fig. 3 is the utility model mixer-settler structural representation.
The specific embodiment:
Level Four mixer-settler as shown in Figure 2, the liquid dynamic sealing device of its mixer-settler as shown in Figure 3, agitator 2 is housed in the mixing chamber 1, be provided with mixing chamber plate washer 4 between mixing chamber and the clarifying chamber 3, be provided with light phase weir 5 and heavy phase weir 6 in the clarifying chamber, the high 100-1000 millimeter of light phase weir aspect ratio mixing chamber plate washer height, the high preferred values of light phase weir aspect ratio mixing chamber plate washer height is the 200-500 millimeter.The liquid movable sealing that has been applied to hydrochloric acid and dichloroethanes system implementation, dichloroethanes density is 1.257 gram per centimeters
3, have inflammable and explosive and chemical property toxicity, belong to heavy phase.Hydrochloric acid density is 1.05 gram per centimeters
3, nonflammable explosive, belong to light phase, play sealing function on cell body top.
The utility model is widely used, and the extractant of the chemical property of density and toxicity inflammable and explosive greater than having of the aqueous solution is as being 1.1614 gram per centimeters with dichloroethanes, density
3Furfural, density be 1.335 gram per centimeters
3Carrene, density be 1.595 gram per centimeters
3Carbon tetrachloride, density be 1.4916 gram per centimeters
3Chloroform be extractant from aqueous solution extraction, all can adopt the utility model device.
