High-Strength Carbon Monoxide Compressor for Toxic Gases - China Suppliers & Factory
Carbon Monoxide Diaphragm Compressor Advantages
1
Absolutely Oil-Free & Zero Leakage Safety Assurance
The metal diaphragm completely physically isolates the process gas from the hydraulic oil and the external environment, achieving 100% oil-free lubrication during compression and thoroughly eliminating the risk of reaction between lubricating oil and carbon monoxide under high temperature. The static seal structure ensures zero external leakage of the gas, fundamentally resolving the safety and environmental hazards caused by toxic gas leakage, and perfectly matching the stringent sealing requirements for carbon monoxide.
2
High Purity Retention & Anti-Contamination Design
The compression chamber is completely independent with a high surface finish. The gas only contacts specially treated wetted parts, with no contamination from wear of internal moving parts. This allows the initial purity of the carbon monoxide gas to be maintained stably over the long term, meeting the raw gas purity requirements for high-end chemical synthesis.
Key Design Points for Carbon Monoxide Diaphragm Compressors
Strict Temperature Monitoring & Over-Temperature Prevention
The minimum auto-ignition temperature of carbon monoxide in air is 588°C. Although its auto-ignition temperature is relatively high, temperature must still be strictly controlled during compressor operation.
The equipment must be configured with multi-stage compression and an efficient inter-stage cooling system to ensure that the discharge temperature at each stage is far below the safety threshold. High discharge temperature alarms and a high-high temperature shutdown interlock must be provided to prevent temperature accumulation due to cooling failure or abnormal operating conditions.
Triple Leakage Protection & Safety Interlock System
Diaphragm Rupture Monitoring:
A three-layer diaphragm design is adopted, equipped with a diaphragm rupture alarm device. Once the gas-side diaphragm ruptures, the pressure change in the middle layer immediately triggers a pressure switch, issuing an audible and visual alarm and interlocking an emergency shutdown of the compressor.
Comprehensive Safety Interlocks:
The system integrates multi-parameter safety interlocks including low suction pressure, high discharge pressure, low lubricating oil pressure, and cooling water failure to execute immediate shutdown procedures.
Material Compatibility & Special Treatment
All wetted parts in contact with carbon monoxide, including the diaphragm, cylinder head, valve seats, etc., must be made of corrosion-resistant high-quality stainless steel (e.g., 316L).
During manufacturing, thorough degreasing, cleaning, and passivation treatment must be carried out to remove surface oils and impurities, preventing catalytic reactions. For operating conditions involving wet carbon monoxide, upgrading to a higher-grade corrosion-resistant alloy must be evaluated.

Frequently Asked Questions
Why are diaphragm compressors ideal for carbon monoxide?
Diaphragm compressors provide an absolutely oil-free compression environment and static sealing. This eliminates any risk of reaction between the lubricating oil and carbon monoxide, while ensuring zero external leakage of this toxic gas.
How does the triple leakage protection system work?
It utilizes a three-layer diaphragm design equipped with a rupture alarm. If the gas-side diaphragm breaks, the change in pressure triggers a switch that sounds an alarm and initiates an emergency shutdown to prevent gas leakage.
How is over-temperature prevented during compression?
The compressors utilize multi-stage compression alongside high-efficiency inter-stage cooling systems. The system also features high discharge temperature alarms and automatic shutdown interlocks to prevent heat accumulation.
What materials are used for parts contacting carbon monoxide?
All wetted parts (diaphragms, cylinder heads, valve seats) are made from corrosion-resistant, high-quality stainless steel (such as 316L) which undergoes degreasing, cleaning, and passivation.
Can these compressors handle wet carbon monoxide?
Yes, but wet carbon monoxide requires evaluation for upgrading to higher-grade, corrosion-resistant alloys to prevent the formation of corrosive acids.
What safety interlocks are integrated into the control system?
The control system integrates critical parameters including low suction pressure, high discharge pressure, low lubricating oil pressure, cooling water failure, and diaphragm rupture to trigger immediate emergency shutdowns if abnormalities occur.
