Catalyst Separator With Blower Unit For Wall Impact Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Catalysts used in petroleum refinery and chemical plants are often damaged during unloading due to high-speed collisions with the walls of traditional separators, leading to inefficiencies and equipment loss.
Innovation Solution
A separator system that uses a blower unit to gently direct gas towards the catalyst, minimizing contact with the separator walls, combined with a container and dumping hose arrangement to ensure safe and continuous unloading, utilizing air as the blowing gas to reduce costs and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional separator is used to separate catalyst from air, then the catalyst can be separated, but the catalyst collides with the wall at high speed and is damaged
Solution Approach 1:
A gas blowing hole is introduced as an intermediary element in the separator. Gas is blown through this hole to create a protective gas flow that cushions the catalyst particles, preventing direct collision with the separator walls while maintaining effective separation and unloading functionality
2Productivity
If the catalyst is ejected into the separator at high speed, then the unloading process is efficient, but the catalyst is likely to collide with the wall and be damaged
Solution Approach 1:
The gas blowing hole creates a protective gas flow in advance before the catalyst particles can collide with the separator walls. This preliminary protective action cushions the high-speed catalyst particles, neutralizing the harmful collision forces while preserving the efficient high-speed unloading process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces catalyst damage and enables continuous, efficient unloading of catalysts while maintaining equipment integrity, allowing for greater quantities of undamaged catalyst to be processed and stored.
Implementation Method 1
a blower unit provided to the separator body for blowing a gas toward a bottom of the separator body to the catalyst sucked by the vacuum unit through the first connection hose
Implementation Method 2
a separator that is capable of separating a catalyst from air while restraining damage on the catalyst, and an unloading device provided with the separator... the catalyst sucked by the vacuum unit through the first connection hose

AI summary
An unloading device includes: a separator connected to a suction hose connected to the reactor and to another suction hose connected to a vacuum car, the separator separating a catalyst sucked from the reactor by the vacuum car from air; a flexible container bag for storing the catalyst dropped from the separator; and a dumping hose provided between the separator and the flexible container bag for transferring the catalyst dropped from the separator to the flexible container bag. The separator includes a blower unit for blowing a gas to the catalyst unloaded in the separator body toward a lower cone and a cover that openably closes a catalyst outlet.
