Description

The static mixer that mixing intensity is adjustable

The utility model belongs to the hybrid technology field, relates to a kind of mixing arrangement that object mixes mutually in the pipeline, static mixer (B01F5/00) that particularly a kind of mixing intensity is adjustable of being used for.

Static mixer is the novel mixing apparatus that external the seventies grows up, this equipment does not have moving component, two or more fluid produces cutting, shears, rotation but the special spiral helicine inner member of the mixing duct inside in the dependence static mixer (also can be referred to as spiral blade, be called mixed cell between following) makes, and reaches the fine dispersion between fluid and mixes fully.With agitator etc. dynamically mixing apparatus compare, it is simple that existing static mixer has flow process, compact conformation, energy consumption is low, small investment, advantages such as installation and maintenance are convenient, be easy to realize serialization and automation, so in oil refining, chemical industry, medicine, departments such as food are widely used in liquid---liquid, liquid---gas, gas---gas, solid liquid---mixing, emulsification, absorb, extraction, reaction, technical process such as heat transfer, but because its structural restriction, the mixing intensity of existing static mixer can not be regulated, and this disadvantage has greatly influenced its result of use.

For example: in petrochemical industry, crude oil electric desalting is one of very important operation, behind the crude oil access to plant, need to inject a certain proportion of water, by mixing, profit is disperseed, increase contact area, the salt in the crude oil just is dissolved into aqueous phase, then under the effect of high voltage electric field, with water-oil separating, the salt in the crude oil has just removed.Obviously, the profit mixing intensity is high more, and oil water boundary is long-pending big more, and salt is just easy more to be removed.After profit is distributed to a certain degree, the water-oil separating difficulty, the salt rejection rate of crude oil and dehydration rate descend.Have an optimum mixing intensity in the electro-desalting of crude oil, existing static mixer can not address this problem.Because the hydrodynamics complexity of calculation will address this problem certain difficulty from design, even solved this problem in the design, because the variation (flow, density, viscosity etc.) of process conditions, best mixing intensity also can change.Because existing static mixer is after the ratio of the fluid of its flow, rerum natura, temperature and required mixing is determined, its mixing intensity is also determined thereupon, can't go to regulate its mixing intensity, this defective causes the result of use of existing static mixer to be subjected to greatly influence when practical application at all.

The static mixer that provides a kind of mixing intensity adjustable is provided the purpose of this utility model, to overcome existing defective in the prior art.

Task of the present utility model is finished by following method, the static mixer that a kind of mixing intensity is adjustable, still adopt the structure of traditional static blender on the whole, mode in mixing duct inside with serial connection is provided with several mixed cells, the two ends of mixing duct are equipped with flange, its key is that the suitable position at the mixing duct tube wall offers at least one aperture, has connected short tube on the described aperture, also is equipped with flange on the free end of short tube.

The flange at above-mentioned mixing duct two ends is used for being connected with input channel and output channel, and the flange on the short tube free end is used for being connected with time fluid line.

The size of small aperture can be determined that the quantity of aperture generally is advisable with four by the degree of regulation decision of mixing intensity, can satisfy the variation of process adjustments in the production so basically according to inferior fluid flow.

In order to guarantee that time fluid can conveniently enter mixing duct, be preferably between each mixed cell and set up centring ring, described aperture preferably is opened on the tube wall of mixing duct of this centring ring position simultaneously.

Below in conjunction with accompanying drawing shown in the embodiment the utility model is described in further detail.

Fig. 1 is the overall structure schematic diagram of the adjustable static mixer of mixing intensity;

Fig. 2 is that the utility model is in ducted configuration schematic diagram;

Fig. 3 is the structural representation of centring ring.

With reference to Fig. 1, be provided with mixed cell 5 in the inside of mixing duct 2, have additional centring ring 6 between the mixed cell 5, the two ends of mixing duct 2 are respectively fitted with hubbed clip-on-welding flange 1, on the tube wall of mixing duct 2, offer four apertures 7, described aperture 7 is in centring ring 6 positions that are arranged between the mixed cell 5 respectively, has connected short tube 4 respectively on each aperture 7, is equipped with slip-on welding flange 3 on the free end of each short tube 4.

With reference to Fig. 2, the input of the static mixer that the hubbed clip-on-welding flange 1 of main fluid input channel A by mixing duct 2 inputs and mixing intensity are adjustable is connected, and the output of the static mixer that the hubbed clip-on-welding flange 1 that output channel C then passes through mixing duct 2 outputs and mixing intensity are adjustable is connected.As can be seen from Figure 2, be connected with time fluid input tube road B on the main fluid input channel A simultaneously, inferior fluid in the inferior fluid input tube road B can enter main fluid input channel A and flow into mixing in the mixing duct 2 with main fluid by valve body b1, inferior fluid input tube road B also is connected with each short tube 4 by the slip-on welding flange 3 on each short tube 4 free end simultaneously, as seen, inferior fluid in the inferior fluid input tube road B also can pass through valve body b2 respectively, b3, b4, b5 flows directly in the mixing duct 2 and mixes with main fluid, perhaps enters output channel C by valve body b6 with main fluid.

Fig. 3 has provided a kind of concrete structure of centring ring 6, and the centring ring with similar structures can guarantee that time fluid conveniently enters mixing duct.

From concrete configuration situation embodiment illustrated in fig. 2 as can be seen, main fluid enters the mixing duct 2 from main fluid input channel A, and inferior fluid then can enter any one appropriate location from valve body b1, b2, b3, b4, b5 or b6.Obviously under the situation that inferior fluid enters from valve body b1, main fluid will be by whole mixed cells 5 with time fluid, its mixing intensity maximum; And under the situation that inferior fluid enters from valve body b6, inferior fluid is not at all by mixed cell 5, so the mixing intensity minimum of main fluid and time fluid.Can learn that according to above analysis inferior fluid enters to b5 successively from valve body b2, then mixing intensity reduces successively, therefrom can select the mixing intensity of optimum production actual conditions, and is adjustable with the mixing intensity that realizes blender.Control method is very simple, needs only unlatching and closes corresponding two valve bodies, just can be implemented in the adjusting of the mixing intensity of line.

The utility model is owing to having adopted said structure, except possessing existing static mixer energy consumption Outside low, small investment, the advantage such as simple to operate, easy to maintenance, it is adjustable to have increased mixing intensity Characteristics. In chemical industry operation, it is in order to wash, make with extra care, extract certain chemical products that two-phase is mixed, Also want two to be separated after the mixing. Mixing intensity is crossed conference and is caused separation difficulty, and the result has affected product Quality and yield, also can cause device to be stopped work when serious. The static mixing that this mixing intensity is adjustable Device has solved the key technology difficult problem in the actual production, so its result of use is better, and the scope of application Wider.
