Round calcium based desulfurizer

SDG adsorbent, commonly known as dry acid gas adsorbent, SDG acid waste gas adsorbent (dry acid gas adsorbent)Calcium based desulfurizer is a desulfurization material mainly composed of calcium minerals, and the calcium sulfur ratio is a key indicator to measure its efficiency. In practical applications, the ratio needs to be controlled according to the process type to balance economy and desulfurization efficiency. This type of desulfurizer converts pollutants into solid gypsum by reacting alkaline calcium compounds with sulfur dioxide in flue gas, and is widely used in flue gas treatment in industries such as steel, power, and chemical. ‌‌

Product Introduction

Calcium based adsorbent is a functional material mainly composed of calcium oxide, calcium hydroxide, or calcium carbonate. Its core application is high-temperature capture of carbon dioxide and industrial flue gas desulfurization. This type of material is currently the most researched and used adsorbent type in the field of industrial emissions reduction due to its cheap raw materials and wide sources

Chemical adsorption: The active calcium components in calcium based adsorbents (such as calcium hydroxide, calcium oxide) can react chemically with acidic gases (such as SO ₂, H ₂ S, CO ₂, etc.) to form stable calcium salts. For example, calcium hydroxide reacts with sulfur dioxide to produce calcium sulfite or calcium sulfate, thereby achieving gas purification. Physical adsorption: The porous structure and high specific surface area (such as 600-1200 ㎡/g) of calcium based adsorbents can adsorb impurity molecules such as VOCs (volatile organic compounds) or heavy metal ions in gases or liquids through van der Waals forces.

  1. Activated carbon adsorbent: Activated carbon has a rich pore structure and a large specific surface area, which can effectively adsorb acid gas molecules. Its adsorption capacity is influenced by factors such as the pore structure, specific surface area, and surface functional groups of activated carbon.
  2. Metal oxide adsorbent: Metal oxides such as zinc oxide, aluminum oxide, etc. have a large specific surface area and abundant active sites, which can adsorb acid gas molecules. The adsorption capacity of metal oxide adsorbents is influenced by factors such as their chemical composition, crystal structure, and surface properties.
  3. Nanomaterial adsorbent: Nanomaterials have unique physical and chemical properties, such as high specific surface area, high porosity, and excellent adsorption performance, which can effectively adsorb acid gas molecules.

  1. It can purify multiple acidic gases simultaneously.
  2. It can achieve extremely high purification efficiency and can be designed according to user needs.
  3. The use and maintenance are extremely simple and convenient.
  4. No special requirements for environmental conditions, no need for antifreeze treatment in winter
  5. Use safely.
  6. No secondary pollution.

  1. Industrial waste gas treatment: Acid gas adsorbents are widely used in industries such as chemical, metallurgical, and petroleum to adsorb and treat sulfuric acid and other acid gases in waste gas, reducing the concentration of waste gas emissions.
  2. Environmental protection equipment: Acid gas adsorbents can be used in the manufacturing of environmental protection equipment, such as acid gas purification towers, adsorption based desulfurization and denitrification devices, etc., to achieve the treatment of industrial waste gas.
  3. Laboratory analysis: Acid gas adsorbents are also widely used in the field of laboratory analysis, such as for pre-treatment of gas samples to improve the accuracy of analysis results.
  4. Flue gas desulfurization: Calcium based desulfurizers are used in industrial scenarios such as coal-fired power plants and steel plants to remove sulfur dioxide from flue gas.
  5. Wastewater treatment: adsorption of heavy metal ions or organic pollutants.
  6. Chemical production: used for capturing and purifying acidic gases such as hydrogen sulfide, hydrogen chloride, etc.

  1. Storage conditions: Keep in a cool and dry place to avoid moisture and clumping.
  2. Operating parameters: It is recommended to control the desulfurization reaction temperature at 120-200 ℃, and the adsorbent replacement cycle should be adjusted according to the actual working conditions.
  3. Safety protection: Wear a dust mask during operation to avoid inhaling dust.
