Product Detailed Description

Product parameters:

  • Temperature range of flue gas entering the absorption tower: 50 - 140℃.

  • Key substances involved and generation conditions: A concentrated chlorine dioxide solution is generated by a chlorine dioxide generator and mixed with natural seawater to form a chlorine dioxide seawater solution for treatment.

  • Liquid-gas ratio: The corresponding liquid-gas ratio is determined based on the flue gas volume and the concentrations of NOx and SO₂.


Product advantages:

  • High-efficiency purification capacity: It can simultaneously remove NOx and SO₂ from the flue gas of marine gas turbines, realize the integration of desulfurization and denitrification, and effectively purify the flue gas so that it meets the emission standards before being discharged.

  • Reasonable resource utilization: The treatment liquid is formed by cleverly mixing natural seawater with a concentrated chlorine dioxide solution, which not only fully utilizes the resource characteristics of natural seawater, but also ensures the treatment effect, and has certain environmental protection and economic benefits.

  • Appropriate temperature control: The flue gas temperature is reasonably controlled by the gas heat exchanger. The flue gas is first cooled to make it more conducive to the reaction when entering the absorption tower, and then the purified flue gas is heated to ensure that the flue gas meets the relevant requirements when it is discharged. The entire temperature control process helps to improve the overall treatment efficiency and effect.


Product Introduction:

The integrated equipment for desulfurization and denitrification of marine gas turbine flue gas is designed to effectively treat the flue gas generated by marine gas turbines. Its working process is as follows: First, the flue gas of the marine gas turbine will pass through the gas heat exchanger to reduce its temperature to 50-140℃ and then enter the bottom of the absorption tower. At the same time, the chlorine dioxide generator will generate a concentrated chlorine dioxide solution, which will be mixed with natural seawater. According to the specific liquid-gas ratio determined by the flue gas volume and the concentration of NOx and SO₂, the chlorine dioxide seawater solution is pumped into the top of the absorption tower with the help of a spray pump, forming mist droplets in the absorption tower, allowing it to fully contact with the flue gas, thereby removing NOx and SO₂. Finally, the purified flue gas will be heated again by the gas heat exchanger and then discharged from the chimney. With its integrated desulfurization and denitrification functions, reasonable resource utilization and appropriate temperature control methods, the equipment provides a reliable and efficient solution for the purification of marine gas turbine flue gas.
