Description

Technical Field

[0001] The utility model relates to the technical field of thermal power generation, in particular to a desulfurization waste gas treatment device for a thermal power generating set. Background Technique

[0002] In the current market, the generating sets configured by many manufacturers mainly rely on fuel engines, with diesel as the main energy source. However, during the startup and operation of diesel engines, waste gas containing various pollutants will be emitted, and these pollutants mainly include particulate pollutants (PART I CULATE), nitrogen oxides (NOx), sulfides (SOx), hydrocarbons (HC), and carbon monoxide (CO) and other harmful components.

[0003] Among the particulate pollutants, particularly noticeable are the fine particles containing ash (SOOT), organic fractions (SOF), sulfates, and metal components, which often appear in the form of black smoke during the startup and operation of the engine. The generation of sulfides stems from the sulfur molecules contained in the fuel, while the organic compounds and carbon monoxide in the waste gas are the direct results of incomplete combustion. These pollutants are not only the main source of the exhaust odor of diesel engines but also have a serious impact on the environment.

[0004] For the existing waste gas treatment system, the discharge of its treatment liquid often remains at a constant level. However, during the actual operation of the generating set, due to the changes in power and load, there are significant differences in the amount of waste gas generated. This constant treatment liquid discharge method often leads to insufficient treatment of waste gas or a large waste of treatment liquid, thereby reducing the treatment efficiency and increasing the operating cost. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model
