How to improve the operating efficiency of the hydrogen compressor?

In today's world, the common problem is the exhaustion of non-renewable energy and the waste of resources. Under the premise of limited energy, how to reduce energy consumption has become the main exploration target and problem for all walks of life. Manufacturers are studying how to improve production efficiencyHydrogen compressor,Oxygen compressor和CO2 compressor.

Improve the operating rate of the hydrogen compressor

Compressor overview and development status

The types of compressors currently available mainly include piston compressors (mainly crankshaft connecting rod), screw compressors, scroll compressors, centrifugal compressors and other compressors with unique structural types. Their working compression ratio is usually less than 10. This is especially true for the compression ratio requirements of models other than piston compressors. Otherwise, the displacement will be reduced to the point where normal operation is lost. There are many types of hydrogen-nitrogen compressors, which are widely used in the production of chemical companies. Their role is very important and has become an indispensable important equipment. Due to the strong continuity of chemical production, take a reciprocating piston nitrogen-hydrogen compressor as an example. In long-term use, there are many reasons for the failure, which may affect normal production, and it may also be caused by the leakage of nitrogen and hydrogen at high flow rates. (Power generation) or in the case of an open flame, it may cause a fire hazard and pose a greater threat to the safety of life and property. Therefore, the failure of the hydrogen nitrogen generator is discovered in time and processed in time, thereby avoiding the vehicle staying overnight and avoiding the breeding and expansion of safety production accidents.

Improve the operating rate of the hydrogen compressor

l Measures to prevent overheating

1. According to the properties of compressed hydrogen and ammonia, select high-grade grease with high flash point after oxidation and less carbon precipitation. The amount of oil injected is appropriate, and the oil quality analysis, oil replacement and oil cleaning are determined. During the inspection and inspection process, supervise the grease used in the hydrogen compressor.

2. Clean the dirt regularly during the operation of the hydrogen compressor to ensure smooth cooling water and cooling water quality. Ensure that the cooling system temperature alarms of the compressor unit and the parking interlock protection device are intact.

3. Always check whether the oil-water separator is working properly, and discharge the separated oil and water in time.

l Anti-overpressure

1. The compressor outlet is equipped with a high-quality check valve instead of a shut-off valve to prevent overpressure caused by load flow after loading.

2. Set high and low pressure alarms at the inlet and outlet of the compressor, and high-pressure over-limit interlocking shutdown protection devices to realize remote automatic monitoring. Prevent accidents.

l Hydrogen sulfide corrosion

1. According to the actual situation of the site, add a simple desulfurization device to reduce the hydrogen sulfide content in the medium and reduce the corrosion of hydrogen sulfide to the internal components of the compressor unit.

2. According to the operating time limit, replace the key components of the compressor to prevent corrosion and other potential accidents.

3. Materials, pipes, fittings, valves, flanges, gaskets, etc. that contact the compressed hydrogen and nitrogen in the booster station have been replaced by sulfur-resistant materials.

l Fire and explosion protection measures

1. The compressor's intake and exhaust pipes are equipped with automatic shut-off valves. In the event of hydrogen-nitrogen leakage, fire or other accidents, the operator can close the shut-off valve in time to cut off the air supply.

2. The booster station adds a combustible gas detection and alarm system to monitor, alarm and interlock the combustible gas that leaks during operation.

3. Periodically perform system testing and leak detection on the booster station.

4. After the compressor overhaul operation is completed, manually shake the compressor when replacing the nitrogen to automatically open the inlet and outlet valves of the compression cylinder to form a loop, and replace the air in the compression cylinder to ensure hydrogen, nitrogen and air during operation. Unrelated.

l Perfect process design

1. Replace the manual control valves at the inlet and outlet of the compressor with automatic control valves to automatically cut off the air supply and release the pressure in an emergency.

2. Install bearing vibration monitoring device and vibration upper limit alarm and over-limit automatic shutdown device for the compressor unit: add bearing temperature intake air temperature monitoring device, temperature upper limit alarm and over-limit automatic shutdown device on the compressor; add shaft displacement to the compressor unit Detection, alarm and over-limit automatic stop device: The compressor dry gas sealing system is equipped with an exhaust over-limit alarm device: the compressor inlet and outlet increase high and low pressure alarms and high jade limit devices.

As the demand for compressors, people are becoming more and more dependent. Improving compressor efficiency means increasing output and bringing higher profits for manufacturers.
