Ammonium sulfate circulating pumpIt is a pump specifically designed for handling solutions containing ammonium sulfate. This pump has a specific design and function to adapt to the characteristics of ammonium sulfate solution and ensure efficient, stable, and safe operation. Its working principle is that the motor is started by the start switch, converting electrical energy into mechanical energy. Mechanical energy generates rotational motion through the impeller inside the pump casing, causing the liquid inside the pump to flow. At the same time, a low-pressure area is formed at the inlet inside the pump casing, which sucks in ammonium sulfate solution. As the impeller rotates, the liquid is pushed to the outlet of the pump casing, forming a high-pressure area, and finally discharged through the outlet pipe.
Ammonium sulfate circulating pumpIt has a wide range of applications, mainly concentrated in the fields of chemical engineering, environmental protection, energy, and agriculture, as follows:
1. Flue Gas Desulfurization (FGD) System - Main Applications
Application scenario: In flue gas desulfurization devices of coal-fired power plants, steel plants, chemical plants, etc.
Specific function:
In the ammonia desulfurization process, the circulation pump is used to forcibly circulate the ammonium sulfate slurry in the absorption tower, allowing it to fully contact with the flue gas and complete the desulfurization reaction.
Transport the ammonium sulfate solution generated by the reaction to the oxidation system or subsequent crystallization and separation processes.
Characteristics: The medium is a slurry containing ammonium sulfite/ammonium sulfate, usually containing a certain amount of dust and solid particles, which requires high wear and corrosion resistance of the pump.
2. Production of fertilizers and compound fertilizers
Application scenarios: Ammonium sulfate is an important nitrogen fertilizer and used in the production of compound fertilizers such as monoammonium phosphate and diammonium phosphate.
Specific function:
In the ammonium sulfate crystallization, evaporation, and concentration sections, a circulation pump is used to forcibly circulate the mother liquor, improving heat exchange efficiency and crystallization effect.
Transport ammonium sulfate solution or slurry to subsequent equipment such as centrifuges and dryers.
Characteristics: High medium concentration, easy crystallization, and the pump needs to have good anti crystallization and self-cleaning capabilities.
3. Chemical production and process cycle
Application scenario: Chemical processes involving ammonium sulfate as raw material, intermediate product, or by-product.
Specific function:
In the production of chemical products such as caprolactam and nylon, it is used to transport process solutions containing ammonium sulfate.
In processes such as rare earth separation and hydrometallurgy, leaching solutions or electrolytes containing ammonium sulfate are treated.
As a supporting circulating pump for equipment such as reaction vessels, evaporators, crystallizers, etc.
Characteristics: It may involve complex media with high temperature, high concentration, or other chemical components, and strict material compatibility requirements for the pump.
4. Wastewater treatment and resource recovery
Application scenario: Processing industrial wastewater containing ammonia nitrogen or sulfate ions.
Specific function:
In systems that use ammonia or ammonium sulfate methods to treat wastewater, a circulation pump is used to transport the ammonium sulfate solution generated by the reaction.
Transforming ammonia and sulfur resources in wastewater into valuable ammonium sulfate products, achieving the goal of "turning waste into treasure".
Characteristics: The medium composition is complex and may contain oil stains, suspended solids, etc., requiring the pump to have good passability and corrosion resistance.
5. Other industrial sectors
Pharmaceutical industry: In some drug synthesis or purification processes, ammonium sulfate is used for salt precipitation and other operations, requiring pumping of relevant solutions.
Food and feed industry: may be involved in the production of specific additives.
Nonferrous metal smelting: In processes such as electrolysis and leaching, the treatment of electrolytes or leaching solutions containing ammonium sulfate.
