Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of desulfurization and denitrification equipment, it is recommended to prioritize checking key technical parameters such as equipment processing efficiency (such as SO2/NOx removal rate) and flue gas flow adaptability range to ensure compatibility with existing emission conditions.
  • When selecting high emission industries such as thermal power and steel, attention should be paid to equipment corrosion resistance and continuous operation stability. In the chemical industry, it is recommended to pay attention to special scenario adaptability such as explosion-proof design.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • The desulfurization and denitrification equipment usually needs to be used in conjunction with the dust removal system. When purchasing, modular design can be considered to simplify later maintenance, while reserving 10% -15% redundant processing capacity to cope with emission standard upgrades.

Knowledge Base

Q

In desulfurization and denitrification equipment, the selection of supporting fans should be targeted according to specific processes (such as desulfurization or denitrification) and operating conditions. The desulfurization system (such as limestone gypsum method) usually uses a desulfurization oxidation Roots blower, while the denitrification system (such as SCR/SNCR) often uses high-temperature process fans or booster fans, both of which have advantages in material, pressure, and temperature resistance

Q

This article provides a detailed introduction to the types and working principles of high-pressure equipment for desulfurization and denitrification, including wet desulfurization and denitrification equipment, SCR denitrification equipment, SNCR denitrification equipment, and combined desulfurization and denitrification equipment, providing comprehensive reference information for practitioners in related industries.

Q

With the rapid development of industrialization, human beings are facing increasingly severe environmental problems, among which the emissions of sulfur oxides and nitrogen oxides are particularly prominent. These harmful substances not only cause environmental problems such as acid rain and photochemical smog, but also have serious impacts on human health. Therefore, the research and application of desulfurization and denitrification technology are particularly important.
