Horizontal screw centrifuge It plays an important role in the application of sludge dewatering in printing and dyeing plants. The wastewater from printing and dyeing plants usually contains solid substances such as pigments, dyes, suspended solids and so on, and the sludge needs to be effectively dewatered when treating these wastewater.
Recumbent snail Centrifuge The solid particles in the printing and dyeing factory wastewater can be separated and dehydrated by the high-speed rotating screw propeller and centrifugal force. Its main applications include:
one Solid-liquid separation : The horizontal screw centrifuge can separate the suspended solid particles in the printing and dyeing wastewater from the liquid, and deposit the solid particles on the inner wall of the centrifugal drum to form a solid layer through centrifugal force, while the clean liquid is discharged from the central shaft hole.
2. Sludge dewatering: The horizontal spiral centrifuge can further dewater the sludge in the printing and dyeing wastewater. Through the rotation of the screw propeller, the water in the sludge is separated and discharged, and the separated sludge has a low water content.
The horizontal spiral centrifuge has the advantages of compact structure, large treatment capacity and good dewatering effect in the application of sludge dewatering in printing and dyeing plants. It can effectively treat the printing and dyeing wastewater sludge with solid substances such as pigments, dyes and suspended solids. However, according to the specific characteristics and treatment requirements of printing and dyeing wastewater, combined with other equipment and processes, comprehensive treatment is required to achieve better dehydration effect and treatment efficiency. It is recommended to consult and discuss with professional equipment suppliers or process engineers in detail to determine the best Dewatering of printing and dyeing sludge Programme.
In the application of sludge dewatering in printing and dyeing plants, the horizontal spiral centrifuge also needs to pay attention to the following points:
1. Sludge characteristics: different types of printing and dyeing wastewater sludge have different characteristics, such as the size, concentration and viscosity of solid particles. When selecting and using horizontal screw centrifuge, it is necessary to understand the characteristics of sludge so as to adjust the operating parameters and treatment scheme of the equipment.
2. Equipment selection: according to the wastewater characteristics and target dehydration effect of the printing and dyeing plant, select a horizontal spiral centrifuge of appropriate specification and model. Different types of centrifuges may have different dewatering capacity and treatment effect.
3. Adjustment of operating parameters: the operating parameters of the horizontal screw centrifuge, such as rotating speed, feed rate, etc., have an impact on the dehydration effect. According to sludge characteristics and treatment requirements, adjust and control these operating parameters to obtain the best dewatering effect.
4. Equipment maintenance: regularly maintain and clean the horizontal screw centrifuge, including cleaning the slag outlet, cleaning the surface and interior of the equipment, to ensure the normal operation of the equipment and extend its service life.
5. Impurity treatment: there may be some special impurities or chemicals in printing and dyeing wastewater, such as dyes, chemicals, etc. In the process of sludge dewatering with horizontal screw centrifuge, the impact of these impurities on the equipment needs to be considered, and the pretreatment or subsequent treatment should be carried out accordingly.
In conclusion, the horizontal spiral centrifuge plays an important role in the application of sludge dewatering in printing and dyeing plants. Reasonable selection of equipment, adjustment of operating parameters and maintenance of equipment will help to obtain the best dehydration effect and treatment efficiency. It is recommended to cooperate with professional equipment suppliers or process engineers to obtain specific printing and dyeing waste water treatment Comprehensive support and guidance required.
