The role of polyurethane cyclone in desulfurization system

2025-02-11

The polyurethane cyclone is made of wear-resistant special polyurethane material, which has good corrosion resistance, high resistance to fluid scouring, long service life and other advantages, and is suitable for harsh working conditions in the desulfurization system.

Wet flue gas desulfurization is a common flue gas desulfurization technology, in which the cyclone plays an important role the process. The working principle of the cyclone mainly relies on the action of centrifugal force, and the separation of the mixture is achieved through high-speed rotation. with other desulfurization equipment, the polyurethane cyclone has the advantages of simple structure, convenient installation and maintenance, and low operating cost. This makes polyurethane cyclone a highly efficient, adaptable, simple in structure, and low-cost desulfurization equipment, which has important significance for environmental protection.

The polyurethane cyclone plays an important role in the desulfurization system, mainly including the following aspects:

Slurry concentration and particle classification：

Polyurethane hydrocyclone is used for slurry concentration and particle classification in the desulfurization system. For example, the gypsum hydrocyclone slurry from the absorber, carries out concentration and particle classification. The dilute overflow returns to the absorber, while the concentrated underflow is sent to the dewatering belt machine for gypsum dewatering.

Gypsum dehydration：

During the gypsum dehydration process, the underflow of the hydrocyclone contains about 45%-50% (mass content) of solids, mainly gypsum crystals. The purpose of the vacuum belt dehydrator is to remove the free water between these large crystal particles.

Coarse-fine separation of limestone slurry：

The polyurethane hydrocyclone is also used for the coarse-fine separation of limestone slurry. The overflow of the hydrocyclone is qualified particle of limestone slurry (sieve rate > 90%) to the limestone slurry tank, as the absorbent to the absorber for reaction. The under of the hydrocyclone is coarse particles continue to return to the mill for grinding.

Wastewater treatment：

Polyurethane hydrocyclone is also used in wastewater treatment system, such as desulfurization hydrocyclone wastewater hydrocyclone direct sale polyurethane hydrocyclone, which is used for fine sand recovery and mud sand separation in mines.

In summary, the polyurethane hydrocyclone plays a crucial role in the desulfurization system, significantly improving the efficiency and effectiveness of desulfurization system through various functions such as slurry concentration, particle classification, gypsum dewatering, limestone slurry separation, and wastewater treatment. At the time, its excellent wear resistance and corrosion resistance also ensure the long-term stable operation of the equipment.
