Desulfurization and oxidation solutions for thermal power industry

In the thermal power industry, desulfurization oxidation is a key process of flue gas desulfurization, the purpose of which is to absorb sulfur dioxide in the absorption tower after the generation of sulfite oxidation to sulfate, so that the desulfurization products can be stabilized to facilitate the subsequent treatment and disposal.

Industry information

Desulfurization and oxidation treatment in the thermal power industry, centrifugal blowers are used as follows

Fume Absorption

The fumes from the thermal power factory enter the desulfurization absorption tower, where a large amount of seawater is pumped into the tower and sprayed down from the top. Seawater has a natural alkalinity and can absorb sulfur dioxide in the flue gas. Sulfur dioxide reacts with the alkalinity in seawater to produce sulfites and other substances.

Oxidation treatment

The seawater absorbed with sulfur dioxide flows out from the bottom of the absorption tower and enters the aeration tank. In the aeration pond, a large amount of air is drummed into the seawater through the aeration device, making the sulfite in the seawater come into full contact with oxygen and undergo an oxidation reaction, which is transformed into sulfate.

Seawater discharge

After oxidation treatment, seawater needs to be restored to meet the seawater quality standards in terms of PH and Chemical Oxygen Demand (COD). After meeting the standard, the seawater can be discharged back to the ocean or used for other purposes.

Desulfurization and oxidation process

Pain point background

Traditional blowers have high energy consumption, lack of precise air supply control, high equipment maintenance costs, serious wear and tear of components, vibration and noise prone to failure, lack of intelligent management easy to appear management mis

Pain Point 1

Due to the gradual reduction of the transmission efficiency of the equipment, energy consumption and maintenance costs continue to rise, leaving companies with certain cost pressures.

Pain Point 2

It is difficult for traditional blowers to accurately monitor the concentration of calcium sulfate during the desulfurization reaction in real time, so it is not possible to accurately control the amount of air supplied to the oxidation blower according to actual demand.

Solution

Xinlei technical team went deep into the site of Zouping County Huineng Thermal Power Co., Ltd. and fully understood the company's actual working conditions and production needs. According to the specific situation of the desulfurization and oxidation process, Xinlei team provided 2 sets of Xinlei magnetic levitation centrifugal blowers to replace the original 3 sets of Roots blowers with a total actual operating power of 882KW.
