In modern thermal power plants, desulfurization is a key process for reducing sulfur dioxide emissions and achieving green production. However, the desulfurization process generates complex desulfurization wastewater and a large amount of sludge. Efficient treatment of this wastewater and sludge is crucial for achieving environmental compliance and resource recovery. Membrane filter presses, with their excellent solid-liquid separation performance, have become the preferred equipment for dewatering and resource utilization of flue gas desulfurization wastewater and sludge in power plants.
Membrane filter presses perform exceptionally well in power plant desulfurization treatment, thanks to their unique membrane secondary squeezing function. After the initial filtration forms a filter cake, the elastic membrane, driven by a high-pressure medium (water or air), performs a secondary squeezing of the filter cake, significantly reducing the moisture content of the filter cake and obtaining a drier, more compact solid product. This process is crucial for desulfurization gypsum dewatering and sludge volume reduction, directly reducing subsequent transportation and disposal costs, and creating favorable conditions for resource utilization.
Automatic Filter Cloth Washing System: Effectively prevents desulfurization gypsum scaling and clogging of the filter cloth, maintaining high permeability and extending the service life of the filter cloth.
Automatic Filter Plate Shaking Device: For highly viscous desulfurization sludge, it assists in the automatic detachment of the filter cake, enabling unattended, fully automatic operation.
Stainless Steel Coating Treatment: To address chloride ion corrosion in desulfurization wastewater, the frame can be coated with stainless steel to ensure structural stability of the equipment in harsh environments.
The filtrate treated by the membrane filter press has effectively purified water quality, making it suitable for reuse or further advanced treatment. Through rational planning and treatment, this filtrate can be reapplied to production processes, such as supplementary water for the desulfurization process, or after further treatment, meet industrial water standards for other production processes with relatively lower water quality requirements. This not only effectively conserves water resources and reduces the enterprise's reliance on fresh water, but also reduces the total amount of wastewater discharge, aligning with the environmental protection concept of sustainable development.
The membrane filter press can thoroughly dewater the solid substances in desulfurization wastewater, transforming them into dry filter cakes. Compared to the sludge state before treatment, the volume of the filter cake is significantly reduced, greatly lowering the difficulty and cost of sludge treatment. The dry filter cake is more convenient for transportation, storage, and final disposal, and also reduces the risk of secondary pollution to the environment caused by sludge.
The membrane filter press can also recover useful substances. Taking sulfur recovery as an example, by specifically treating desulfurization wastewater, the membrane filter press can effectively separate and concentrate the sulfur components in the filter cake. After appropriate processing, the sulfur can be recovered and reused. Converting waste into marketable by-products not only improves the comprehensive utilization rate of resources but also creates additional economic benefits for the enterprise.
As the "cleaner" of power plant desulfurization processes, the membrane filter press not only solves the problems of wastewater and sludge disposal but also improves the overall energy efficiency of the plant through secondary pressing and intelligent configuration. If you are looking for an efficient and durable desulfurization wastewater treatment solution, Quanhong Filtration membrane filter press will be your ideal choice.
