1, The impellers, volute casing, guard plates and other wet parts fluid molded lines of ZGTX desulfurization absorption tower slurry circulating pump, ZGT series desulfurization slurry pump, TZ series standard chemical process pump adopt solid-liquid two-phase flow hydraulic models developed by well-known domestic universities based on China’s FDG characteristics. This design makes pumps more efficient and more suitable for FGD absorption tower slurry circulation and the operating conditions of slurry delivery pump. Field practice has proved that our products are cavitation-resistant and have no concentrated wear. The efficiency and abrasion-resistance ability of our pumps are higher than the current FGD on-site desulfurization pump!

2. ZGTX absorption tower desulfurization slurry circulation pump provides various materials such as Cr30, CD-4MCu, 2605, 2205, 304, 316, and 316L according to different working conditions. The wet part components are of all-metal construction, which has less water friction, and they are more efficient than the non-metal pumps with the same parameter. Its geometric dimensions are easy to control; its spare parts have smooth surfaces; the gap between the parts is small; its volumetric efficiency is high; and the overall efficiency is higher than that of the nonmetal pump.

3. In the sealing structure of ZGTX absorption tower desulfurization slurry circulation pump, wear-resistant plates are used to replace the choma, because the wear of the choma by the slurry will result in a rapid decline in pump efficiency. The diameter of the pump shaft is large and the cantilever is short, which reduces the deflection of the shaft during operation, thereby extending the service life of the seal. The pump is arranged in a back-pull structure with an extended diaphragm coupling, which is easy to maintain. When the impeller, mechanical seal and shaft assembly are removed, the whole set of rotor parts can be pulled out from the motor end without removing the inlet and outlet pipeline of the pump and the motor. The shaft seal is a combination structure of mechanical seal and back blade. The back blade can prevent solid particles from entering the mechanical seal so that to extend the service life of the mechanical seal. The cartridge mechanical seal is easy to disassemble and replace. The rotating and static rings are both silicon carbide, which is more suitable for the sealing of slurry media. The material of static seal is PTFE; other metal parts are not in contact with the medium to avoid corrosion of the mechanical seal.

Understanding ZGT Series Desulfurization Pumps

The Benefits of Using ZGT Series Desulfurization Pumps

Investing in the ZGT series desulfurization pumps offers numerous advantages for industrial applications. Engineered for efficiency and durability, these pumps feature a robust design that is ideal for handling the harsh conditions of flue gas desulfurization processes. The hydraulic models used in these pumps are tailored to meet the specific characteristics of China's FDG, making them more effective and resistant to cavitation and wear.

High-Quality Construction Materials

One of the standout features of the ZGT series pumps is their construction from high-quality materials such as Cr30, CD-4MCu, 2605, 2205, 304, 316, and 316L. These materials ensure the pump components have minimal water friction, enhancing their efficiency. Moreover, the all-metal construction offers superior geometric accuracy and smoother surfaces, which translate to higher volumetric and overall efficiency compared to non-metal pumps.

Innovative Sealing Mechanisms

The ZGT series pumps also come with advanced sealing mechanisms. The use of wear-resistant plates to replace choma ensures prolonged efficiency as it minimizes wear. Additionally, the combination of mechanical seals and back blades helps to keep solid particles away from the mechanical seal, extending its lifespan. These features collectively ensure the pump remains efficient and reliable over long periods of operation.

Effective Methods of Desulfurization and Denitrification

A comprehensive range of technologies is available for flue gas desulfurization and denitrification. These can be broadly categorized into wet, semi-dry, and dry methods, each with its own set of benefits and drawbacks.

Wet Flue Gas Desulfurization Technology

This is the most mature and widely applied technology, known for its high efficiency (typically over 90%) and reliability. Wet desulfurization involves gas-liquid reactions that are fast and efficient, making it a preferred choice for various industrial applications.

Dry Flue Gas Desulfurization Technology

Dry desulfurization is beneficial for its simpler equipment requirements, lower investment and operating costs, and ease of disposal of desulfurization products. However, it generally has a lower desulfurization efficiency, making it suitable for specific use-cases where lower efficiencies are acceptable.

Emerging and Advanced Technologies

New technologies like microbial desulfurization, membrane absorption, and sodium sulfide desulfurization are being explored for their potential to offer higher efficiencies and lower environmental impact. These methods are still in the experimental or early implementation stages but show promise for future applications.
