Static mixer
Static mixer is a kind of high-efficiency mixing equipment without any movable elements. Beside wide applications in the fields of oil refining, chemical engineering industries, the mixer can also be used in the fields of medical science, foodstuff, mine refining, plastic squeezing and environment protection department. Compared with traditional mixers, glue ground, venturi, the static mixer is characteristic of simple flow process, compact structure, low energy consumption, less investment, easy operation, free maintenances as well as good performance. At the case of liquid—liquid, liquor-solid, air-air mixing, emulsification, neutralization, absorption, abstraction, reaction and reinforcement heat conduction, the kind of static mixer can be used to replace traditional equipments.
Denotation of product types
Calculation for pressure loss of static mixer
The static mixer is to be used in the pipe with large pressure loss. When the systematic pressure of the static mixer rises high, the pressure loss can be ignored, while the systematic pressure of the static mixer becomes lower, the pressure loss of the static mixer should be calibrated. Method for the calculation for pressure loss of static mixer differs depending on the model of static mixer. Referring to the calculation of static mixer, please contact our Technical Division of the Company.

Installation of static mixer
During installation, the static mixer should be at the location of the original mixing of two streams or multiple streams. In cases of different usage, the erecting modes differ. The concrete requirements see the following table:
|
Type
|
Installation mode |
|
SV |
Gas-liquor phase: vertical installation (parallel flow or diverse flow installation)
Liquid–gas phase: horizontal or vertical installation (from the bottom up), similar effect .
Gas-gas phase: horizontal or vertical installation (small gas-gas phase density difference, no directional limitation) |
|
SX |
Liquid –liquid phase: horizontal or vertical installation (from the bottom up), similar effect |
|
SL |
Liquid –liquid phase: horizontal or vertical installation (from the bottom up), similar effect
Liquor –solid phase: horizontal or vertical installation (from the bottom up) |
|
SH |
Gas-liquor phase: The flange dimension for two terminals depends on the nominal diameter of Company’s products, by SL installation mode |
|
SK |
Liquor-liquor phase: (vertical installation, from the top to the bottom)
Liquor –solid phase: horizontal or vertical installation (from the bottom up) | Notes: Gas-liquor phase refers to that the gaseous phase flow is working medium flow while liquid phase is passive medium flow
Liquor–gas phase refers to that the liquid phase flow is working medium flow while gas phase flow is passive medium flow.
Notes for order
(1) To help you to have a good selection of ordering the products, please offer the following parameters: a. working medium; b. flow rate kg/h; c. operating pressure Mpa; d. operating temperature 0C; e material viscosity cp; f. substance density kg/m2 g. permissive pressure loss Mpa; h. flange standard; i. material of equipment.
(2) The flange standards of mixers produced by our company refers to HG, HGJ, JB/T, SH, ANSI etc., customers should clear flange standards and specifications during ordering, otherwise misers are to be provided according to HG20592-1997 standard.
(3) If the customer selects products with sleeve, parameters such as maximum operating pressure, max operating temperature, working medium should be noted.
Associated equipment：SN distributor
■ Product features
During the process of fluid transfer, the mixing ration is affected by unbalanced transferring pressure. In order to facilitate the customers to used static mixer, our company has recently developed a new SN-type allotter with injection function to the pressure pump. On condition of guaranteeing the sub-flow rate and making the outlet pressure satisfied. The SN-type allotter consists of a spray nozzle, a reception chamber, a mixing chamber and a diffuser. The main stream passes through the conical inlet in high speed and then forms into low-pressure stream, thus making the sub-stream pumped into the reception chamber. High-pressure vortex (eddy current) in the mixing chamber is diffused through the diffuser that makes the fluid into the static mixer smoothly for optimal effectiveness.
■ Product application
SN distributor is suitable to fluid feeding with two or more than two streams. When pressure of main stream and sub-stream is unbalanced, Venturi-type distributor can be selected while the pressure of main stream and sub-stream is balanced, normal type distributor can be selected.
■ Sketch of SN distributor
Normal- type distributor Venturi - type distributor
■ Notes for order
SN distributor works for different process conditions, our company will offer special design and produce any kind of allotters on request of customers.
