Polymerizable Substance Handling Device With Protrusion Spray and Grid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling devices for easily polymerizable substances, such as (meta)acrylic acid, face issues with polymer formation due to stagnation in internal spaces like maintenance holes, leading to polymerization and device stoppages, despite the use of polymerization inhibitors.
Innovation Solution
A handling device comprising a flow unit, protrusion unit, spray unit, and grid is designed to prevent polymer generation by allowing a spray unit to wet the inner wall surface of the protrusion unit, while the grid prevents irregular packing from entering the internal space, ensuring continuous operation and reducing polymer removal costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a packed column with irregular packing is used for capturing and purifying easily polymerizable substance, then purification efficiency is improved, but polymer formation occurs in internal spaces where substance stagnates
Solution Approach 1:
The spray unit is installed in advance in the protrusion unit to spray liquid (polymerization inhibitor or easily polymerizable substance) onto the inner wall surface before polymerization can occur. This preliminary action prevents polymer formation in the internal space where stagnation would otherwise occur, resolving the contradiction between maintaining purification efficiency and preventing polymer formation.
2Reliability
If polymerization inhibitor is added to prevent polymerization, then polymer formation is suppressed, but the inhibitor is consumed at stagnation places and becomes insufficient
Solution Approach 1:
The invention extracts the function of preventing polymerization from the bulk polymerization inhibitor and relocates it to the spray unit positioned in the protrusion unit. This localized delivery system targets only the internal space where stagnation occurs, preventing polymer formation without requiring excessive amounts of polymerization inhibitor throughout the entire system, thus reducing overall inhibitor consumption.
3Ease of operation
If maintenance holes are provided in the packed column, then access for maintenance is improved, but internal spaces are created where substance stagnates and polymers form
Solution Approach 1:
The spray unit acts as an intermediary between the maintenance hole and the internal space. It delivers liquid (polymerization inhibitor or easily polymerizable substance) onto the inner wall surface of the protrusion unit, preventing polymer formation in the internal space while maintaining the maintenance hole for access. This intermediary action resolves the contradiction between providing maintenance access and preventing polymer generation.

Function Achieved in This Case
The device effectively prevents polymer formation in internal spaces, promoting continuous operation and reducing maintenance costs by using a grid to contain packing and a spray unit to wet the inner surfaces with polymerization inhibitors.
Implementation Method 1
spray liquid onto the inner wall surface of the protrusion unit
Implementation Method 2
spraying, on the inner wall surface of a device such as a maintenance hole at a stagnation place, liquid that would accumulate on a tray inside a column
