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
Strict Distinction of Material Corrosion Resistance Based on Moisture Content
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
Integrated Safety Purge and Purging 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
Targeted Diaphragm Cavity and Monitoring Design
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 (FAQ)
Why is a diaphragm compressor ideal for chlorine gas applications?
Diaphragm compressors utilize a static seal design that separates the gas process chamber from the hydraulic oil system. This ensures 100% oil-free compression and eliminates the risk of toxic chlorine gas leaks into the atmosphere.
How does moisture content affect material selection for chlorine compressors?
For dry chlorine (moisture content ≤ 0.05%), carbon steel can be used. However, if moisture is present, chlorine forms corrosive hydrochloric acid, requiring all wetted parts to be constructed from high-grade corrosion-resistant alloys, such as 316L stainless steel.
What is the purpose of the three-layer diaphragm rupture alarm system?
The system serves as an active safety barrier. If any layer of the three-layer diaphragm fails, a pressure switch immediately detects the pressure change, triggering an alarm and an automatic interlock shutdown to prevent gas contamination or leakage.
Why is nitrogen purging required before starting up the compressor?
Nitrogen purging expels ambient air and moisture from the piping and compressor systems. This prevents the formation of explosive gas mixtures and corrosive environments when chlorine is introduced.
What explosion-proof rating is required for the electrical instruments?
To operate safely in potentially explosive gas environments, all electrical components and instruments must meet an explosion-proof rating of at least Ex d IIB T4.
