The horizontal screw centrifuge is suitable for solid-liquid separation treatment of sewage, sludge and other solid and liquid in various industries. It is used in the treatment of papermaking wastewater
It also played a significant role.
During papermaking operations, a large amount of wastewater is discharged from both pulp and paper making. The wastewater generated from pulp production is severely polluted. The wastewater discharged during pulp washing is
Black brown, also known as black water, has a high concentration of pollutants with a BOD of 5-40g/L. It contains a large amount of fiber, inorganic salts, and
Pigments. The wastewater discharged from the bleaching process also contains a large amount of acidic and alkaline substances. The wastewater discharged from the paper machine is called white water, which contains
A large amount of fibers and fillers and adhesives added during the production process.

As a highly precise equipment, it is essential to grasp the selection criteria when choosing a centrifuge. Here we introduce to everyone
The factors to consider when choosing a centrifuge are as follows.
When choosing a centrifuge, the main factors to consider include the following: (1) density, viscosity, and surface tension of the liquid phase material
power. (2) The separation of materials mainly involves solid or liquid phase materials. (3) Particle size, density, and hardness of solid materials
Degree. (4) The flammability and explosiveness of materials. (5) Affinity, concentration, and all charge properties (positive charge) of solid and liquid phase materials
(6) Sludge properties: The higher the organic matter content and oil content of the sludge, the worse the dewatering performance. (7) The material's
rate of recovery. (8) The volatility of materials. (9) The corrosiveness of materials. (10) Speed difference: Its size not only affects processing energy
Strength also affects the processing effect. (11) When solid materials are crystalline products, it is required that the degree of crystal damage during separation be low
There are special requirements for the structure and unloading methods of the equipment. (12) Sludge treatment capacity, for a certain specification of centrifuge, output
The water efficiency changes with the increase of sludge treatment capacity. In order to achieve the expected goal, select the appropriate machine with the appropriate treatment capacity based on the sludge volume
Type is very important.
As long as you can grasp these 12 factors when choosing a centrifuge, you can choose a device that is more suitable for yourself,
It also plays an important role in the development of enterprises

Definition and application fields of bacterial tubular centrifuge
Bacterial tube centrifuge is a device specifically designed for the separation of bacterial cells and bacteria in the biological industry. It has been uniquely designed based on the original tube centrifuge, making it more suitable for the separation of bacterial cells. This device is widely used in various fields such as food, chemical, petroleum, water treatment, and pharmaceuticals

The three-phase horizontal spiral centrifuge (tricanter )is driven by the main motor to rotate the drum at full speed. The material is continuously introduced into the spiral through the feed pipe and evenly distributed to the spiral discharge port. Under the action of centrifugal force, the solid phase settles on the drum wall and is pushed out by the spiral pusher towards the slag outlet of the conical drum. The liquid phase flows out along the spiral towards the overflow hole at the large end of the drum, forming a small end with solid phase and a large end with liquid phase. Separate solid particles from the liquid in the mixture, or separate two immiscible mixtures with different densities.

Centrifuge in petroleum sulfonate production application 
In the quality standard of petroleum sulfonate, the content of disorderly chemical substances is one of the key index values for the inspection of sulfonate, and becomes the key factor for the production of sulfonate. How to reasonably separate the disordered chemical substances from crude petroleum calcium sulfonate, and how to completely separate the acid residue of micro particles from acid-base oil, has become an obstacle to improve the quality of petroleum sulfonate series products. The application of high-speed suction filtration technology has solved this problem in essence. Gravity separation technology gravity separation is the application of the relative density of each component in the combined solution is not the same, the heavy phase moves down to the bottom of the vessel, while the light phase floats on the surface, and the middle of the light and heavy phase is converted into a certain page. The higher the relative density difference, the faster the separation rate. In the process of sulfonate processing, gravity separation is only to remove the slag of large particles. The relative density of acid residue and calcium residue is about 0.4g/cm3 higher than that of oil. The smaller acid slag and calcium slag are floating in the product oil in the form of opacification liquid, which is difficult to separate from the product oil with the help of relative density difference, and can only be separated with the help of mechanical equipment.

In fact, the structure of the centrifuge is not complicated. It can be thought of abstractly, just like the marshmallow machine of the street marshmallow vendor，In fact, it is a very general centrifuge structure. In natural time science research experiments, the requirements for centrifuges must be higher.
Due to the difficult problems in the application industry of centrifuges, it is crucial to stipulate the materials of centrifuges. Because the separated materials are different, the materials are also different. Therefore, on a very large level, when customers choose and purchase centrifuges, they should prepare complete materials in advance, especially in which industry they will use more in the middle and later stages. It is a key stage in the purchase of centrifuges.
The centrifuge is based on the fact that when the mixture with fine particles is still, the floating particles move down slowly due to the effect of gravity field. The heavier the particles are, the faster they move down. On the contrary, the particles with smaller relative density will move up. The velocity of the particles moving in the gravity field is related to the size, shape and relative density of the particles, as well as the compressive strength of the gravity field and the viscosity of the liquid. The number of particles with the size of red blood cell is mu; m. The whole process of their settlement can be observed under the general force effect.
