Abstract

The invention discloses a kind of mixed methods of different pressures fluid, it is shunted by the fluid to high discharge pressure, shunting is allowed successively to be mixed with the fluid of low first class pressure, gradually reduce the pressure difference between high pressure fluid and low-pressure fluid, achieve the purpose that mix different pressures difference fluid gradually, its method is simply applicable in, is easily operated, the different fluid of high pressure differential and high flow capacity difference can be made, which to be sufficiently mixed, uniformly can be widely used in the various experimental studies or production for needing to carry out fluid mixing.

Description

A kind of mixed method of different pressures fluid

Technical field

The present invention relates to fluid mixing techniques field, especially a kind of mixed method of different pressures fluid.

Background technique

It includes isolating state, non-isolated state and part isolation state completely that different fluid, which carries out mixed admixture, no matter No matter which kind of admixture is conveyed all when the discharge pressure between mixed fluid has big difference using pump conveying or gravity The mixing that will lead between fluid is extremely uneven, can cause adverse effect to the use of subsequent fluid-mixing.

Summary of the invention

The technical problems to be solved by the present invention are: providing a kind of mixed method of different pressures fluid, can make different defeated It is uniformly mixed between the fluid of pressurization pressure.

To solve above-mentioned technical problem the technical scheme adopted by the invention is that: a kind of mixing side of different pressures fluid Method, comprising the following steps:

A, multiple fluid pressing force height to be mixed is ranked up, first the progress highest first order fluid of pressure with The mixing of the high second level fluid of pressure second；

B, first order fluid is shunted, the series of shunting is according to the pressure between first order fluid and second level fluid Difference is allocated, and series is at least 2 grades；

C, the pipeline with multiple branch pipes is taken, the shunting of first order fluid is passed through pipeline from the entrance of pipeline, and according to It is secondary that the remaining shunting of second level fluid and first order fluid is each led into pipeline from each branch pipe；

D, the fluid-mixing flowed out from pipe outlet is subjected to the mixing with third level fluid, subsequent progress by above-mentioned steps With the mixing between remaining fluid.

Further, the inner cavity of the pipeline is the Venturi tube being connected.

Further, the shunting series in step b is 2~6 grades.

The beneficial effects of the present invention are: the present invention is shunted by the fluid to high discharge pressure, allow shunting successively with The fluid of low first class pressure is mixed, and gradually reduces the pressure difference between high pressure fluid and low-pressure fluid, reaching makes not With the purpose that pressure difference fluid gradually mixes, method is simply applicable in, is easily operated, can make high pressure differential and high flow capacity difference not Being sufficiently mixed with fluid uniformly can be widely used in the various experimental studies or production for needing to carry out fluid mixing.

Detailed description of the invention

Fig. 1 is mixture length schematic diagram of the invention.

Specific embodiment

To facilitate the understanding of the present invention, the present invention is further detailed with reference to the accompanying drawings and embodiments.

Embodiment 1

As shown in Figure 1, being mixed to the fluid of fluid a, fluid b and tri- kinds of fluid c different discharge pressures, first by three Kind fluid sorts by the height of discharge pressure, is followed successively by fluid a, fluid b, fluid c.Fluid a is shunted, split into a1, A2, a3, a4 will shunt a1 and from the entrance of pipeline be passed through pipeline, fluid b is passed through pipeline from first branch pipe of pipeline, allow point Stream a1 is mixed with fluid b progress first time, then will be shunted a2 from second branch pipe of pipeline and is passed through pipeline, and allow and shunt a1 and stream The fluid-mixing of body b carries out second of mixing with a2 is shunted, and then successively carries out fluid-mixing and shunts a3, shunts mixing for a4 It closes, finally obtains the fluid-mixing i.e. fluid-mixing ab of fluid a Yu fluid b.Followed by the mixed of fluid-mixing ab and fluid c It closes, fluid-mixing ab is shunted, ab1, ab2, ab3, ab4, ab5 are split into, mixing is shunted into ab1 and is led to from the entrance of pipeline Enter pipeline, fluid c be passed through pipeline from first branch pipe of pipeline, allows mixing to shunt ab1 and mixed with fluid c progress first time, Then mixing is shunted into ab2 and is passed through pipeline from second branch pipe of pipeline, the fluid-mixing for allowing mixing to shunt ab1 and fluid c is same Mixing, which shunts ab2 and carries out second, to be mixed, and is then successively carried out fluid-mixing and is shunted ab3, mixing shunting ab4, mixes with mix The mixing for shunting ab5, finally obtains the fluid-mixing after fluid a, fluid b and fluid c are sufficiently mixed.

It present invention can be suitably applied to the mixing between the fluid of a variety of different discharge pressures, be suitable for pressure difference 20~200 The mixing of fluid between times, the channel mixed using Venturi tube as fluid, the resistance generated to fluid is small, Venturi tube Diffuser can make different fluid gradually slow down upon mixing, reduce the mixed pressure loss of fluid, guarantee different pressures difference stream Body mixes uniform.
