Efficient Plate Heat Exchanger Cleaning: Unveiling the Power of Automatic Backwashing

Plate Heat Exchanger Cleaning systems utilize automatic backwashing mechanisms to reverse the flow and cleanse the shell-and-tube or plate-and-frame exchangers. This reversal, coupled with heightened flow velocity, yields several advantageous outcomes:

1. Mitigation of biomass accumulation within the unit.
2. Removal of debris and sediments.
3. Prolongation of the unit’s lifespan while reducing maintenance expenses.

An Eqoflush Flow Reversal Valve can be effortlessly integrated into the supply and return pipelines. It periodically alters the flow direction through the exchanger for brief intervals, seamlessly maintaining operation. Within less than a minute, the flow reverts to its regular direction. Employing periodic backwashing via an automatic Plate Heat Exchanger Cleaning system dislodges accumulated solids, thereby extending the duration between operational interruptions for cleaning.

Benefits of Automated Plate Heat Exchanger Cleaning

Avoid the buildup of the following types of Fouling:

Biomass Accumulation:
Biomass accumulation, stemming from algae spores, small eggs, and larvae, poses a significant challenge within heat exchangers, particularly adhering to low-flow areas. This issue can be mitigated by maintaining a flow rate exceeding 0.2 m/s. During backflushing, low-flow zones experience heightened velocities, deterring biomass adhesion. However, the cement-like hardening of algae deposits, occurring within hours, necessitates chemical or mechanical cleaning methods for removal.

Debris Clogging:
Debris, including algae, seaweed, mud, and leaves, presents another concern, potentially obstructing the inlet side of heat exchangers. Even with strainers in place, clogging remains a risk, demanding automated cleaning systems, albeit at a higher investment and maintenance cost compared to backflush valves.

Particulate Buildup:
Fine particles like silt, sand, and suspended solids infiltrate plate heat exchangers, accumulating between plates, thereby inducing plugging and fostering scaling and pitting.

Reduce Maintenance and extend Gasket Lifespan:
Implementing backflushing reduces the frequency of plate heat exchanger cleaning interruptions, which primarily involve the disassembly and reassembly of plates, thereby prolonging gasket lifespan. Given the expense of gasket replacement, such measures significantly curtail maintenance costs.

Backflushing widely accepted as effective strategy to boost efficiency

Chemical Processing, November 2012:

Backflushing effectively combats fouling in heat exchangers by reversing flow direction periodically. This process dislodges biomass, debris, and fine particles, minimizing clogging and scaling issues. Automated backflushing systems offer cost-effective maintenance solutions, reducing the need for frequent manual cleaning and extending gasket lifespan. (summarized).

Heating Plumbing Air Conditioning, October 2016:

Altering flow direction enhances heat exchanger performance. By periodically reversing flow, debris buildup is minimized, extending equipment lifespan and reducing maintenance costs. This strategy improves overall efficiency and ensures optimal heat transfer. (summarized)
