Pipeline jet desulfurization technology Hebei Jisheng is the most professional

Pipeline jet desulfurization technology Hebei Jisheng's most professional pipeline jet lime slurry desulfurization process uses the flue between the boiler and the dust collector as a reactor for desulfurization. It does not require an additional absorption container, so its process investment is greatly reduced, and the operation is simple and requires There are fewer venues. There are currently many small and medium-sized boilers in our country, and it is not suitable to use processes with high investment and high energy consumption. Therefore, with small investment and low operating costs, the simple and practical pipe injection process is a more suitable choice.
Process flow
The induction injection process is a process in which calcium-based or sodium-based desulfurization absorbent is injected between the air preheater at the end of the boiler and the electrostatic precipitator or bag dust collector for flue gas desulfurization.
The pipeline spray desulfurization process has the following methods
Dry slaked lime, humidification is required
Dry sodium-based absorbent, no humidification is required
Lime slurry or in-pipe washing, no separate Humidification steps
Water spray humidification has two functions
Strong absorbent activity, improve desulfurization rate
Dust-saving characteristics to maintain the performance
Pipe spraying has low Investment, low energy consumption, simple installation, easy modification, no waste water discharge and other advantages. But at the same time, there are also some shortcomings that hinder its application
The fly ash contains unreacted lime, which causes the fly ash to harden after humidification, making ash treatment more difficult
The possibility of wall contamination increases< br/>The sulfur rate is not too high.
