Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sand removal methods for cooling towers, such as self-cleaning sand filters and mesh filters, are inefficient in removing accumulated sand from the bottom of the cooling tower, leading to poor sand removal effects and high water consumption.
Innovation Solution
A sand removal device comprising a flushing assembly with a first pipeline that sprays liquid towards the bottom of the cooling tower through multiple water outlets and a cyclone sand removal assembly that extracts and treats the liquid, improving sand removal efficiency while reducing water consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If self-cleaning sand filter or mesh filter is used to remove sand from cooling water, then sand removal capability is provided, but water consumption is too large and accumulated sand at the bottom cannot be removed
Solution Approach 1:
The flushing assembly performs preliminary action by spraying liquid towards the bottom of the cooling tower to stir and flush accumulated sand before the cyclone sand removal assembly processes the water. This preliminary flushing action ensures that accumulated sand is brought up into the main water flow for effective removal, while the system maintains low water consumption by using a small amount of flushing liquid that is recycled through the circulation pump.
2Reliability
If self-cleaning sand filter or mesh filter is used to remove sand from cooling water, then sand removal is attempted, but accumulated sand at the bottom cannot be removed resulting in poor sand removal effect
Solution Approach 1:
The flushing assembly performs preliminary action by spraying liquid towards the bottom of the cooling tower to stir and flush accumulated sand before the cyclone sand removal assembly processes the water. This preliminary flushing action ensures that accumulated sand is brought up into the main water flow for effective removal, significantly improving the overall sand removal effect.
Solution Approach 2:
The invention uses hydraulic principles by employing a circulation pump to circulate liquid through the flushing assembly and back into the cooling tower bottom, creating a continuous flushing action. The cyclone sand removal assembly also utilizes hydraulic principles by using liquid flow to separate and remove sand particles, achieving effective sand removal that conventional filters cannot accomplish.
3Device complexity
If conventional sand removal methods are used, then structure complexity is reduced, but sand removal effectiveness is poor due to inability to handle accumulated sand
Solution Approach 1:
The invention merges two functional components into a unified sand removal system: the flushing assembly that handles accumulated sand at the bottom and the cyclone sand removal assembly that processes the main water flow. This combination allows the system to effectively remove both accumulated and suspended sand particles, achieving high sand removal effectiveness while maintaining reasonable structural complexity through integrated design.
