Abstract

A tubular static mixer relates to improved mixing equipment with fluid as the carrier in chemical engineering, metallurgy and environmental engineering. The utility model is characterized in that a tube is arranged along the fluid direction inside the shell of the mixer in parallel order; the parallel tubes in the mixer are in a group or some groups with certain distance away from each other. The utility model has the advantage that turbulent flow frequency spectrum produced during falloff of even turbulent flow are mainly high frequency and short wave length. A strong partial velocity gradient is produced in the fluid, which greatly increases relative moving speed of different reacting matter and improves the mixing speed and efficiency. By taking advantage of dynamic energy of falloff of turbulent flow, the utility model is available for save 50% energy consumption compared with ordinary mixing equipments. The mixing is available for be completed in a few seconds by excellent mixing function of impinging stream, which reduces the mixing time and equipment space.

Description

The shell and tube static mixer

Technical field:

The utility model belongs to mixing equipment and technology, and relating to a kind of is the improvement of the mixing apparatus of carrier with the fluid in chemical industry, metallurgy and environmental project.

Background technology:

At present, applied mixing apparatus in chemical industry, metallurgy and environmental project, its deficiency is slow in local slight part mixing of materials speed, and weak effect mixes fully inadequately, and mixed process needs the long period just can finish.The main cause that causes the problems referred to above is that general mixing arrangement only designs according to DIFFUSION IN TURBULENCE mechanism, and the diffusion of the material of local slight part belongs to the laminar flow diffusion, and diffusion velocity is slow.Generally speaking, the physical-chemical reaction speed in the heterogeneous fluid is very fast, just can quicken entire reaction course as long as improve the speed of mixing diffusion.To mixing diffusion process, the speed of DIFFUSION IN TURBULENCE is very fast, and therefore, the efficient that improves trickle laminar flow diffusion just can improve mixing efficiency, and then improves the efficient of physical-chemical reaction.

Summary of the invention:

Technical problem to be solved in the utility model is:

A kind of shell and tube static mixer is provided, this blender can make the liquid stream of the blender of flowing through form the RANGE IN HOMOGENEOUS ISOTROPIC TURBULENCE state, and be that it fully develops the enough spaces of reservation, utilize turbulence energy to greatest extent, the mixing of materials process of local slight part is strengthened, improve mixing velocity and mixing efficiency.

The technical solution of the utility model is:

Be provided with tubulation along the liquid flow path direction in the blender shell, each tubulation is side by side and is arranged in parallel, and the tubulation side by side in blender can be one group or array, and each tubulation group is interrupted and is arranged in the blender.

The tubulation radius is 10---500 millimeters, tubulation length is 2 of radius---and 40 times.

The tube section of tubulation is circle or regular polygon.

The beneficial effects of the utility model are:

1, the turbulent flow spectrum concentration that forms in the RANGE IN HOMOGENEOUS ISOTROPIC TURBULENCE attenuation process is at high band, the frequency height, and wavelength is short.In liquid stream, form stronger local velocity's gradient, increased the relative moving speed of differential responses materials greatly, improved mixing velocity and efficient;

2, owing to made full use of turbulence decay kinetic energy, the more conventional mixing apparatus of the utility model can be saved 50% energy consumption;

3, the good immixture of percussion flow is finished mixed process in the several seconds, has shortened incorporation time and has reduced equipment volume.

Description of drawings:

Fig. 1 is an overall structure profile of the present utility model;

Fig. 2 is of the present utility model 1---the circular tubulation profile in 1 cross section;

Fig. 3 is of the present utility model 1---1 cross section regular hexagon tubulation profile;

Fig. 4 is of the present utility model 1---1 cross section square tubulation profile;

Wherein: the 1st, blender shell, the 2nd, charge pipe, the 3rd, tubulation, the 4th, adpting flange.

The specific embodiment:

After liquid stream A enters blender, add liquid phase or solid-phase material B, behind the tubulation of flowing through, form RANGE IN HOMOGENEOUS ISOTROPIC TURBULENCE and, form high-frequency vortex, several materials are fully mixed along the journey decay through charge pipe.
