Low temperature regenerative dehumidification system
2024.05.27
In the increasingly competitive lithium enterprises, the production process produces a large amount of waste heat, the general treatment is directly discharged to the outside world, which has a great impact on the deterioration of the environment around us, and wasted a lot of available energy, so the energy consumption and emissions has been a lithium production of a headache and can not be avoided. How to reduce the emission of waste heat, while reducing the energy consumption of the production process, and make full use of and recycle the industrial waste heat for the lithium industry's biggest goal of energy saving, but also has been one of the important topics of our modern industrial development, Fung Hang Environment to the global market to introduce a new product FXLTD dehumidification system, the purpose of which is to recycle industrial waste heat. The FXLTD system of Fung Hong is different from the general rotor, it has the characteristics of efficient desorption and dehumidification at the regeneration temperature of 50℃ (even below 50℃), which means that the FXLTD system is able to use a large amount of waste heat discharged to the atmosphere in the modern industry (the waste condensation heat of the refrigeration machine, the steam condensate, and other industrial waste heat) as a regenerative heating heat source. I. Innovative combination of refrigeration system and dehumidification system The refrigeration system is composed of four basic parts: refrigeration compressor, condenser, evaporator and throttle valve. They are connected in turn with piping to form a closed system, the refrigerant in the system is constantly circulating, state changes, and heat exchange with the outside world. Among them, the evaporator is the equipment for conveying cold, in which the refrigerant absorbs the heat of the cooled object to realize refrigeration. Condenser is a low-grade heat release equipment, the heat absorbed in the evaporator together with the compressor work is converted into heat together with the cooling medium to take away. General refrigeration system, condensation heat is discharged into the atmosphere and other cooling media. Fung Hong environmental research and development of low-temperature regenerative dehumidification unit, the rotor material is different from the ordinary rotor, you can use the general waste heat (from the refrigeration machine and other such as air compressors, etc. discharged) as a regenerative heat source (45 ℃ ~ 75 ℃) on the air dehumidification. Significantly increase the lithium production costs down space. Second, low-temperature regeneration dehumidification unit energy-saving technology analysis of energy saving is the country strongly advocate the theme: rational use of electricity, saving electricity, as well as some of the waste energy into electricity, hot water and so on has become a top priority in energy saving and emission reduction work. Such as air compressors used in the production process, refrigeration machines will produce a large amount of heat, discharged into the air is not only a major waste of energy is also a major pollution of the environment, the use of reasonable methods to convert heat into hot water for reuse. Combined with the characteristics of the process requirements of lithium batteries, Fung Hang Environment adopts the following energy-saving measures: lithium battery production, such as mixing workshop, coating head and tail workshop and other common areas of the relative humidity requirements are not high, the general relative humidity requirements are 20-40% RH, Fung Hang Environment designed low-temperature regeneration system dehumidifiers, which are characterized by: a) regeneration of energy consumption of 0, all the use of the air compressor and chiller waste heat recovery b) The use of automatic control, the efficient use of hot water. Third, the low-temperature regeneration dehumidifier investment and return analysis a) After the actual application of case studies, the general equipment running 3-6 months to recover the one-time investment costs. b) Ordinary rotor dehumidifier regeneration temperature requirements to reach 110 ℃ or more, while the low-temperature regeneration system regeneration temperature of only 50 ℃ is enough, at the same time can be utilized to recover waste heat, regeneration energy consumption is basically 0. c) low-temperature regeneration system can be utilized to use high-temperature ice water, in order to increase the refrigerator's energy-efficiency ratio. When the chiller ice water temperature is 7 degrees, the COP of the chiller is 4.5-5; when the chiller ice water temperature is 11 degrees, the COP of the chiller can reach 6-6.5. energy efficiency ratio increases the corresponding power requirements will be reduced. d) the use of energy-saving units, due to the power distribution power reduction, equipment distribution room investment, equipment cable investment, can save a lot of investment costs.
