Solution Overview
Problem
In flue gas desulfurization systems, solid components accumulate on the bottom surface of the desulfurized flue gas inflow chamber, requiring periodic servicing operations to maintain system stability and efficiency.
Innovation Solution
The system incorporates a desulfurized flue gas inflow chamber with a protrusion zone featuring inclined protrusions, where cleansing solution discharge pipes are arranged between adjacent protrusions, allowing for effective removal of solid components and stabilizing the absorber solution surface level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cleansing solution is discharged into the absorber solution chamber through a down comer, then solid components can be flushed down, but the surface level of the absorber solution fluctuates causing unstable desulfurization performance
Solution Approach 1:
The patent extracts the harmful effect of cleansing solution discharge from the absorber solution chamber by providing a separate discharge path. The cleansing solution is discharged to the outside of the system through a discharge port in the desulfurized flue gas inflow chamber, preventing it from entering the absorber solution chamber and causing surface level fluctuations.
Solution Approach 2:
The patent segments the discharge function by providing multiple discharge ports positioned between adjacent protrusions on the bottom surface. This segmentation allows for distributed discharge of cleansing solution and solid components, improving discharge efficiency while preventing accumulation in specific areas.
2Ease of operation
If multiple discharge pipes are installed in the desulfurized flue gas inflow chamber, then solid component removal is improved, but solid components accumulate between the pipes requiring periodic servicing
Solution Approach 1:
The patent applies local quality by shaping the bottom surface with protrusions that have inclined top surfaces. This creates localized areas where solid components are directed away from the discharge pipes and toward the discharge ports positioned between the protrusions, preventing accumulation in the critical pipe areas.
Solution Approach 2:
The protrusions on the bottom surface have curved inclined surfaces that guide the flow of cleansing solution and solid components. The curved geometry directs solids away from the discharge pipes and toward the discharge ports, preventing accumulation and reducing maintenance needs.
3Ease of manufacture
If the bottom surface is made flat, then construction is simple, but solid components accumulate requiring periodic servicing
Solution Approach 1:
Instead of making the entire bottom surface complex, the patent introduces protrusions only in specific locations where solid component accumulation is most problematic. The protrusions have inclined surfaces that actively guide solids toward discharge areas, while the rest of the bottom surface remains relatively simple in construction.

Function Achieved in This Case
This design suppresses solid component accumulation, reducing maintenance needs and stabilizing desulfurization performance by ensuring efficient cleansing solution discharge and preventing surface level fluctuations.
Implementation Method 1
the protrusion zone being located at a position lower than an adjacent surrounding area on the bottom surface... allowing for effective removal of solid components
Implementation Method 2
solid components (mainly gypsum) contained in the liquid droplets that accompany the flue gas led into the desulfurized flue gas inflow chamber settle there and accumulate

AI summary
A flue gas desulfurization system that suppresses accumulation of solids on the bottom surface of the desulfurized flue gas inflow chamber of the system is provided. the system includes an absorber solution chamber so that the flue gas can be blown into the solution, a desulfurized flue gas inflow chamber for receiving the inflow of the desulfurized flue gas, a gas flow pipe penetrating between the absorber solution chamber and the desulfurized flue gas inflow chamber to allow the desulfurized flue gas to pass through the pipe, a cleansing solution feed pipe for feeding cleansing solution into the desulfurized flue gas inflow chamber, and at least one cleansing solution discharge pipe, discharging the fed cleansing solution from the desulfurized flue gas inflow chamber. The desulfurized flue gas inflow chamber has a bottom surface including a protrusion zone having a plurality of protrusions. Each protrusion has an inclined top surface.
