In modern industry, desiccant dryers, as key equipment in compressed air systems, are increasingly drawing attention from companies due to their energy consumption issues. How can we achieve high efficiency and energy savings while reducing operational costs? At this moment, we will show you the site where desiccant dryer energy-saving upgrades and renovations, to explore new possibilities for green production!
Traditional desiccant dryers always face issues such as high energy consumption, significant air loss, low regeneration efficiency, and unstable drying effects during operation, which not only increase operation costs but also imposes unnecessary environmental burdens.
To address these issues, Ingersoll Rand has proposed a new energy-saving upgrade and renovation solution for desiccant dryers, including:
1. Regeneration System Innovation: Through replacing traditional compressed air regeneration with a scroll blower and high-efficiency heater, compressed air consumption can be reduced from 8%-15% to 3%. Adding a water cooler can further reduce compressed air consumption to ‘zero.’
2. Smart Control Centre Upgrade: A Siemens control system with an imported dew point meter monitors the dew point of the adsorption tower in real time, extending the regeneration cycle and reducing electricity consumption. Additionally, dual-action solenoid valves are integrated, enabling the system to retain settings during power outages.
3. Adsorbent Upgrade: Based on user’s dew point requirement, an alumina and molecular sieve dual-layer bed structure is adopted to enhance adsorption capacity and oil resistance, achieving a pressure dew point of -40°C to -70°C.
We understand that the implementation phase is critical for the application of technology. To ensure you clearly understand the entire renovation process and facilitate efficient progress, we will break down the renovation steps for the adsorption dryer on-site:
1. Factory Prefabrication: To accelerate the on-site renovation process, we prefabricate the blower skid and some pipelines at the factory before shipping them to the user's site.
2. On-Site Safety Training: Safety training for on-site renovation workers is essential, and specialized workers must ensure their certifications are valid.
3. Pre-renovation Preparation: Carefully inspect the delivered renovation materials, count the quantities, and prepare tools like welders and cutters, ensuring they are in good condition.
4. On-site disassembly of old equipment: Close valves under safe conditions, disassemble old components step by step. Take care to protect surrounding equipment.
5. On-site renovation installation: Cut and weld pipes and brackets according to new design requirements, assemble new parts, check bolt tightness, and install control air circuits.
6. Electrical wiring: Connect wires precisely according to the electrical diagram, ensuring insulation and grounding at critical points.
7. Commissioning and trial operation: After mechanical and electrical installation is completed, set operating parameters and commission the equipment. Open the valves to start the system after commissioning, monitor and record during operation, and address any issues immediately.
8. Electricity consumption monitoring: Continuously monitor the electricity consumption of the air compressor station after renovation to assess energy-saving effect.
Actual measurement data shows that the operation efficiency of the desiccant dryer has improved significantly, with a substantial reduction in energy consumption. After the renovation, the pressure dew point is stable below -40°C, enhancing the quality of the compressed air supplied to users. Additionally, a set of air compressor equipment was successfully shut down, resulting in annual electricity savings of 300,000 yuan.
The Ingersoll Rand desiccant dryer energy-saving upgrade renovation offers users four benefits:
1. Users retain their existing assets.
2. No changes are required to the existing piping system.
3: The upgrade is completed on-site within 2-3 days, enabling rapid resumption of production.
4: Users achieve the same energy-saving effects as new equipment at a lower cost.
The energy-saving upgrade of desiccant dryers is not only a technological innovation but also a commitment to sustainable development. Let us join hands and embark on this wonderful journey towards green energy efficiency, together creating a better future!
