Chlorine Diaphragm Compressor Advantages
01
Absolutely Oil-Free & Zero Leakage Seal
The "static seal" structure of the diaphragm compressor ensures that the gas is 100% free from contact with lubricating oil, fully meeting the "absolute oil-free" requirement for chlorine compression. Simultaneously, its embedded diaphragm head or combined oil distribution plate design significantly reduces sealing surfaces. Coupled with high-strength bolt pre-tightening, it achieves zero leakage containment of highly toxic chlorine, preventing the escape of poisonous gas that could harm personnel and the environment, and also preventing external moisture from entering the system and causing corrosion.
02
Ultra-High Gas Purity Maintenance & Active Safety Protection
This structure absolutely guarantees that the purity of the compressed chlorine is free from any contamination. The standard three-layer diaphragm rupture alarm system is key to active safety. When any layer of the diaphragm experiences an anomaly, a pressure switch immediately triggers an audible and visual alarm and automatically initiates an interlock shutdown to prevent the incident from escalating. This characteristic makes it especially suitable for electronic-grade high-purity chlorine or chemical processes with stringent cleanliness requirements.
Key Design Points for Chlorine Diaphragm Compressors
01
Material Corrosion Resistance
Material selection is the decisive factor in chlorine compressor design. For dry chlorine with a moisture content strictly controlled to ≤ 0.05% (by weight), carbon steel may be considered for wetted parts. However, for the vast majority of operating conditions where moisture may be present, chlorine reacts with water to form hydrochloric acid, necessitating the use of high-grade corrosion-resistant alloys. Technical agreements typically mandate that all wetted metal parts be made of 316L stainless steel or higher grade materials, with special requirements for welding procedures and surface passivation treatment to address potential stress corrosion cracking induced by chloride ions.
02
Safety Purge System
Before startup, the compressor and the entire piping system must be thoroughly purged with high-purity nitrogen or inert gas to expel air and moisture, preventing the formation of explosive mixtures or corrosive environments. The design must integrate dedicated purge and vent connections and valve groups to ensure the operating procedures can be executed simply and reliably.
03
Diaphragm Cavity & Monitoring
The diaphragm must be made of a special alloy material resistant to chlorine corrosion. The diaphragm cavity profile needs to be optimized to extend diaphragm life. The system must be equipped with comprehensive temperature and pressure monitoring. The discharge temperature should be controlled within a safe range (typically well below the general limit of 180°C) through efficient inter-stage coolers, with over-limit alarms and shutdowns configured. All electrical instruments must meet an explosion-proof rating of at least Ex d IIB T4 to suit the potentially explosive environment.

Frequently Asked Questions
Why is a diaphragm compressor ideal for chlorine compression?
The static seal structure of a diaphragm compressor ensures that the gas has 100% zero contact with lubricating oil, meeting the strict "absolute oil-free" requirement essential for safe chlorine compression.
How does the compressor achieve zero leakage for highly toxic chlorine gas?
It features an embedded diaphragm head or combined oil distribution plate design that minimizes sealing surfaces. Combined with high-strength bolt pre-tightening, it prevents toxic gas escape and external moisture ingress.
What happens if a diaphragm ruptures during operation?
The compressor is equipped with a standard three-layer diaphragm rupture alarm system. If any layer fails, a pressure switch immediately triggers an audible and visual alarm and automatically shuts down the system.
How does moisture content affect material selection for the compressor?
Dry chlorine (moisture ≤ 0.05%) allows carbon steel wetted parts. However, if moisture is present, it forms corrosive hydrochloric acid, requiring wetted metal components to be made of 316L stainless steel or higher corrosion-resistant alloys.
Why is a nitrogen purging system required before starting the compressor?
Purging the compressor and piping with high-purity nitrogen or inert gas before startup expels air and moisture, preventing the formation of highly corrosive environments or explosive mixtures.
What explosion-proof rating do the electrical instruments meet?
All electrical instruments and monitoring systems are designed to meet an explosion-proof rating of at least Ex d IIB T4 to ensure safety in potentially explosive processing environments.
