Solution Overview
Problem
Existing continuous polymer production apparatuses require multiple pressure-resistant vessels, piping, and significant energy to operate, making resource conservation, energy conservation, and equipment cost reduction difficult, and they face issues with evaporation components countercurrents that inhibit polymerization reactions.
Innovation Solution
A continuous polymer production apparatus with a housing chamber containing sequentially connected reaction vessels communicating via a gas phase, where a baffle narrows the cross-sectional area between vessels to prevent evaporation components from moving countercurrently, ensuring efficient polymerization reactions by condensing them back into the reaction mixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple pressure-resistant polymerization vessels are connected in series with piping and transfer equipment, then continuous polymer production is achieved, but equipment complexity and energy consumption increase significantly
Solution Approach 1:
Multiple reaction vessels are merged into a single housing chamber, eliminating the need for separate pressure-resistant vessels and external piping. The reaction vessels share a common housing chamber and communicate through a gas phase part within the chamber, integrating what were previously separate components into one unified structure.
Solution Approach 2:
The housing chamber serves multiple functions simultaneously: it contains the reaction vessels, provides the gas phase communication pathway, acts as a containment structure, and eliminates the need for separate piping systems. This multi-functional design reduces overall equipment complexity while maintaining continuous production capability.
2Productivity
If multiple pressure-resistant polymerization vessels are connected in series with piping and transfer equipment, then continuous polymer production is achieved, but energy consumption increases significantly
Solution Approach 1:
The harmful element of external piping and transfer equipment is extracted from the system. By eliminating these components and using internal gas phase communication within the housing chamber, the energy required for pumping and transferring materials between separate vessels is removed, significantly reducing overall energy consumption.
3Temperature
If evaporation components are allowed to move freely through the gas phase part, then condensation occurs on vessel walls, but this causes liquid volume bias and reaction solution drying in certain vessels
Solution Approach 1:
The housing chamber is divided into different regional zones with distinct functions: reaction zones where polymerization occurs and a gas phase communication zone where evaporation components circulate. This spatial differentiation allows condensation to occur in controlled areas without disrupting the liquid volume balance in reaction vessels, maintaining reaction stability.
4Loss of substance
If evaporation components condense on vessel walls, then resource conservation is improved, but reaction progression is inhibited due to liquid volume bias
Solution Approach 1:
The gas phase part acts as an intermediary medium between reaction vessels, allowing evaporation components to be transported and condensed in a controlled manner. This intermediary zone enables resource conservation through condensation while preventing direct interference with reaction vessel liquid volumes, thus maintaining reaction progression.
