Electrolyzer Accessories — Anode & Cathode Cell Inlet Distribution
Pipe for Chlor-Alkali Plant
Product Overview
The Anode and Cathode Cell Inlet Distribution Pipe is a critical component in the chlor-alkali electrolyzer system. Its primary function is to distribute the electrolyte or other process solutions evenly into the electrolytic cell, ensuring stable, efficient, and uniform electrochemical reactions.
1. Material Selection
The inlet distribution pipe must exhibit excellent corrosion resistance and chemical compatibility with the electrolyte solution. Commonly used materials include:
PVC (Polyvinyl Chloride):
Suitable for low-temperature and mildly corrosive environments.
PP (Polypropylene):
Offers enhanced corrosion resistance and is applicable for
moderate- to high-temperature electrolysis processes.
PTFE (Polytetrafluoroethylene):
Exhibits outstanding resistance to strong acids and alkalis; ideal
for highly demanding electrolysis environments.
Titanium, Titanium Alloy, and Nickel Materials:
Provide superior corrosion resistance under high-temperature and
high-concentration acidic conditions.
(In the design shown below, titanium and nickel materials are
adopted for enhanced durability and performance.)
2. Structural Design Features
a. Flow Uniformity
The pipe design ensures uniform electrolyte distribution within the electrolyzer, preventing local concentration gradients
that could cause uneven reactions or reduced efficiency.
b. Pressure Control
The inlet pressure is carefully regulated to maintain optimal flow
rates, avoiding turbulence or uneven deposition inside the cell.
c. Anti-blocking Design
Equipped with optimized apertures and filtration structures, the pipe prevents impurities from clogging the flow path and
ensures stable electrolyte delivery.
d. Temperature Resistance
Designed to operate reliably under varying electrolyte temperatures
without deformation, aging, or material degradation.
3. Installation and Maintenance
a. The inlet pipe is typically connected to a circulation pump or electrolyte storage tank to provide continuous electrolyte flow.
b. The system is designed for easy disassembly and cleaning, ensuring convenient maintenance and minimizing downtime.
c. Pressure sensors and flow meters can be installed to monitor real-time inlet conditions, ensuring
consistent electrolytic performance.
d. Advanced systems may include automatic control devices to dynamically regulate electrolyte inflow based on cell liquid
level and concentration parameters.
Electrolytic Cell Anode Half Shell
Function and Importance
The anode half shell forms a structural and functional part of the anode assembly
within the electrolytic cell. It serves multiple critical roles:
Uniform Current Distribution
Ensures even current flow throughout the cell, promoting consistent
electrochemical reactions and improving product quality.
Protection and Extended Anode Life
Manufactured from corrosion-resistant materials, the anode half shell protects the anode body from chemical attack
by the electrolyte, thereby extending its operational lifespan.
Structural Stability
Enhances the mechanical strength of the anode, maintaining
structural integrity and preventing deformation or mechanical
failure during electrolysis.
Applications
Anode half shells are commonly used in electrolytic extraction and refining processes — including copper, aluminum, and other non-ferrous metals — to ensure stable electrochemical performance, improved product
quality, and enhanced production efficiency.
