Applications of industrial filter cloth and filter mesh - horizontal vacuum belt filter - limestone desulfurization, gypsum treatment

With increasingly stringent environmental protection policies, **flue gas desulfurization (FGD)** systems for coal-fired power plants and large industrial facilities have become crucial for emission reduction and control. In wet desulfurization technology, the limestone-gypsum method dominates due to its maturity and economic viability. The solid-liquid separation of the desulfurization byproduct—gypsum slurry—directly determines the overall system efficiency and byproduct quality. In this critical process, horizontal vacuum belt filter presses, as the main equipment, are widely used for their continuous, efficient, and highly automated characteristics. One of the core components supporting their high-performance operation is a customized industrial filter cloth and filter mesh system.

Limestone desulfurization and gypsum processing “ Unsung hero ”

—— Core application of industrial filter cloth and filter mesh in horizontal vacuum belt filter

With the continuous tightening of environmental protection policies, the ** flue gas desulfurization system ( FGD ) ** has become a top priority for emission reduction and control. In wet desulfurization technology, limestone - gypsum method occupies the mainstream due to its maturity and economy, and the desulfurization by-product —— gypsum slurry solid-liquid separation directly determines the operating efficiency and by-product quality of the entire system.

In this key link, horizontal vacuum belt filter is widely used as the main equipment due to its continuous, efficient, and highly automated characteristics. One of the core components supporting its high-performance operation is the customized industrial filter cloth and filter mesh system 。

A key link in the wet desulfurization process: Gypsum slurry dehydration

In the limestone desulfurization reaction tower, the limestone slurry reacts with SO ₂ in the flue gas to produce calcium sulfite, which is further oxidized to produce dihydrate gypsum ( CaSO ₄ · 2H ₂ O ) 。The resulting gypsum slurry usually has the following characteristics:

  • Low solid content (generally 15% approximately);
  • Many fine particles, the particle size distribution is concentrated in 5-30 microns;
  • The slurry contains impurities such as chloride ions and ferrous ions, which are easy to corrode;
  • High requirements for filtrate clarity, filter cake moisture content, and processing capacity.

Therefore, the choice of filter material is crucial and determines the commercial quality of gypsum and the economic efficiency of equipment operation.

Xiamen Citius (citius-filter) Solution: Stable, efficient, and corrosion-resistant filter cloth and filter mesh system

Xiamen Citius (citius-filter) Filter Materials Technology Co., Ltd. Combining thirty years of technological accumulation, for FGD system-matched horizontal vacuum belt filter provides professional industrial filter cloth and filter mesh with the following advantages:

1.  High-throughput structure, improves filtration speed

  • Multi-layer weaving design combined with high air permeability monofilament substrate allows gypsum slurry to pass through quickly, significantly improving the processing capacity per unit area ；
  • Precise control of fiber gaps ensures good filtrate clarity and prevents particle penetration.

2.  Good filter cake formation, strong peelability

  • Smooth surface treatment + Precise mesh structure allows the gypsum filter cake to form quickly and easily peel off;
  • Reduces secondary pollution and scaling risks, helping to ensure continuous equipment operation.

3.  Corrosion-resistant and wear-resistant, durable

  • Materials use acid and alkali resistant, oxidation resistant high molecular synthetic fibers;
  • The filter cloth is specially post-treated to resist chloride ion erosion and wear, extending service life 。

4.  Support mesh + Main filter cloth collaborative structure, enhances system stability

  • The support filter mesh can use double-layer composite weaving or metal wire mesh, effectively dispersing the operating tension of the equipment;
  • The overall fabric belt structure is stable, ensuring that the filter cloth does not undergo excessive deformation or damage under high vacuum and continuous operation.

Application effectiveness example: For gypsum processing “ Reduce burden and increase efficiency ”

Xiamen Citius (citius-filter) The filter cloth system has been widely used in many coal-fired power plants and chemical desulfurization devices, with significant results:

  • Filter cake moisture content reduced to 8-12% easy to store, transport or use as building material;
  • Filtrate clarity meets the standard for reuse reducing water consumption;
  • Cloth and mesh replacement cycle significantly extended reducing equipment maintenance costs;
  • The filter cloth runs stably, reducing vacuum system fluctuations and slurry leakage failures 。
