Hydro-Cyclone Manifold Flushing to Prevent Dead Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydro-cyclone systems experience deposits and dead zones in manifolds due to fluid flow division, leading to inefficiencies and potential clogging, particularly in large throughput volumes requiring multiple hydro-cyclones.
Innovation Solution
The system incorporates elongated manifolds with flushing connections at their ends, allowing fluid or suspension to be introduced or extracted to create turbulence and prevent deposits, optionally using additional hydro-cyclones to enhance flow and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple hydro-cyclones are used to handle larger throughput volumes, then the purification capacity is improved, but the fluid flow must be divided into multiple smaller partial flows which creates dead zones and deposits in the manifolds
Solution Approach 1:
The patent applies preliminary action by introducing a flushing connection at the end of the manifold that is closed off after the last hydro-cyclone. This flushing connection allows fluid to be introduced into the manifold in advance or during operation to prevent dead zones and deposits from forming, thereby maintaining purification capacity while preventing the harmful effect of deposits.
2Device complexity
If the manifolds are closed on one side to simplify the structure, then the manufacturing complexity is reduced, but dead zones and deposits are created in the region of the closed end
Solution Approach 1:
The patent extracts the harmful effect by introducing a flushing connection at the previously closed end of the manifold. This allows fluid flow to be extracted or introduced at the end of the manifold, preventing dead zones and deposits from forming in that region, while maintaining the simplified closed structure for manufacturing purposes.
3Quantity of substance
If the fluid flow is divided into multiple smaller partial flows for larger throughput, then the system can handle higher volumes, but the flow dynamics are compromised leading to deposits
Solution Approach 1:
The patent implements feedback by using the flushing connection to introduce fluid into the manifold at the end, creating a counter-flow or additional flow that maintains proper flow dynamics. This feedback mechanism ensures that even when the main flow is divided into multiple partial flows, the flow patterns remain effective and do not create dead zones or deposits.

Implementation Method 1
Hydro-cyclones are well suited for concentrating heavy and light particles in pulp suspensions by centrifugal forces and discharging them via the outlet or separator.
Implementation Method 2
a fluid or a suspension is guided via at least one flushing connection into or out of the corresponding at least one manifold

AI summary
A system for purifying a fibrous suspension consists of multiple hydro-cyclones arranged adjacent to one another in a row, each of the hydro-cyclones having at least one feed connection, one accepted stock connection and one reject material connection, and having at least one supply manifold which is connected to multiple feed connections and/or having at least one accepted stock manifold which is connected to multiple accepted stock connections and/or having at least one reject material manifold which is connected to multiple reject material connections, the manifold being elongated and the corresponding connections discharge at their longitudinal side into the corresponding manifold. At an end of at least one manifold which follows the final hydro-cyclone, a fluid or a suspension is guided via at least one flushing connection into or out of the manifold.
