Flue gas desulfurization gypsum dehydration project

1. Project Background:
In the wet flue gas desulfurization (WFGD) system of a national large-scale thermal power plant, continuous and efficient solid-liquid separation is required for the gypsum slurry produced.. The existing dehydration equipment has problems such as low filter cake degree, easy clogging of filter cloth, high energy consumption, and poor on-site environment, which restrict the commercial utilization of by-product gypsum.

II. Challenges and Needs:

Large processing capacity, requiring continuous and stable operation.

The moisture content of the filter cake should be less than 10% to meet the quality standards for gypsum resource utilization (such as making gypsum boards).

The equipment needs to have excellent corrosion resistance and anti scaling characteristics.

Improve the working environment and achieve clean production.

III. Nuclear Xu Solution:

We provided it with  PBFHorizontal Belt Vacuum Filter  Customized solutions:

1.Efficient dehydration zone design: Optimized the layout of the vacuum box and the support structure of the filter belt, extended the effective filtration time, and ensured sufficient dehydration..

2.Corrosion and Wear resistant Configuration: The contact material part is made of SS316L stainless steel and special composite materials, and the filter belt is selected with high porosity and anti clogging models..

3.Intelligent control system: Integrated PLC and touch screen, realizing automatic adjustment and interlocking control of filter belt tension, correction, speed and vacuum degree, and can be connected to the factory DCS system..

4.Three stage filter cloth flushing system: It uses a combination of high-pressure water, low-pressure water, and compressed air to thoroughly clean the filter cloth and maintain high permeability..

Fourth, Application Effect and Customer Value:

Dehydration efficiency: The average moisture content of the produced gypsum filter cake remains stable.; 9%Below, far exceeding customer expectations.

Stable operation: The device has a fault free operation rate of over 99%, significantly reducing maintenance costs..

Economic benefits: High quality gypsum can be directly sold as building materials, creating significant economic benefits..

Environmental benefits: The filtrate is clear and directly reused in the desulfurization system, achieving zero wastewater discharge and resource recycling..
