New energy industry cooling project application

The chiller has many application scenarios in the new energy industry, such as the cooling of battery material grinders, and the cooling of the slurry reactor, for example, the reactor needs to be kept at a suitable temperature during the reaction process, which is usually maintained in a jacket Water at a constant temperature to maintain the normal reaction of the materials in the reactor.

Jiangxi Ganfeng Lithium Co., Ltd. is a manufacturer of lithium compounds, metallic lithium and lithium battery products. During the work of its reactor, it needs to provide a large amount of circulating chilled water in the range of 5 degrees to ensure the normal reaction of materials and reduce the rate of unqualified products. After a number of investigations and studies, the customer project leader determined to choose the cooling scheme of the Kadley water-cooled unit to ensure the temperature environment required for the normal reaction of the materials.


Reducing the temperature of the reaction kettle is a production task with a greater difficulty factor. Incorrect or unmatched selection of the chiller will affect the normal production of the enterprise in the later period. Not only does the energy consumption increase, it also causes environmental pollution, but it also adds additional enterprise unnecessary Funding budget.


In the cooling scheme of Kaydeli chiller, it fully integrates the process production parameters of the materials in the customer's reaction kettle, giving priority to the basic temperature difference of the material reaction needs, that is, the outlet temperature is 8 degrees and the inlet temperature is 2.5 degrees. Automatic control, automatically adjust the operation of the refrigeration system according to the actual temperature of the material.

This refrigeration scheme uses a KDS-100SLA water-cooled screw chiller as the main cooling device, with a cooling capacity of 335KW. It uses a compressor from the Taiwan Hanbell brand, which has low vibration operation, low noise, and a lower failure rate. Capacity adjustment greatly saves energy consumption;


In addition, it is equipped with 4 internal circulating water pumps and 2 external circulating water pumps to ensure the circulating water supply between the reaction kettle and the refrigeration unit, the water tank and the water tower in time.


This solution not only adopts the optimized design of energy saving, but also makes great savings in terms of labor costs. The main control system of the KDS chiller adopts the German Siemens PLC program controller, which realizes one-key start and stop and automatic start and stop of the reactor kettle cooling system, and records and monitors the operation status of the refrigeration unit in a timely manner, without the need for 24-hour personnel on duty. Save labor costs.

This refrigeration solution has been tested by customers, and the entire chilled water circulation system is very stable in refrigeration projects. The customer was very satisfied and trusted with Kaydeli chiller equipment. Soon after, the customer purchased four sets of KWB-015DB oil cooling units to satisfy the cooling of hydraulic oil for automatic production line equipment, and recommended Xinyu Ganfeng and Fengxin Ganfeng Several branch companies such as Industry adopted Kadeli industrial refrigeration unit solutions, all of which achieved good refrigeration results and ensured production progress.


So far, several chillers of Kaydeli have been operating stably for 55 months. The initial water-cooled twin-screw chiller has been running for 97 months. It has been running well, and the equipment has no faults, which fully meets the production needs of enterprises. And exceeded customer expectations, greatly saved energy and labor maintenance costs, and improved the competitiveness of enterprises in production equipment.


At present, the development of the new energy industry is more stable. The competition of enterprises in the post-epidemic era has begun to shift to product quality, energy conservation and emission reduction, and the selection of efficient and energy-saving engineering refrigeration solutions will be the innovation and management strategy of production equipment for new energy enterprises optimization.
