The company has developed a material drying system based on a transcritical carbon dioxide heat pump, including a condensing tower, a transcritical carbon dioxide heat pump, a circulating water pump, an auxiliary cooler, and a sprinkler connected to the auxiliary cooler through the water outlet pipe of the auxiliary cooler. The non-condensable gas pipeline on the top of the tower, the vacuum pump installed on the non-condensable gas pipeline, the belt dryer with material inlet and material outlet and connected with the transcritical carbon dioxide heat pump through the drying high-temperature air pipeline, located in the transcritical carbon dioxide heat pump The circulating fan installed between the belt dryer and the drying high-temperature air pipeline is connected to the belt dryer through the moist hot air pipeline, connected to the transcritical carbon dioxide heat pump through the dry hot air pipeline, and connected to the condensate through the steam pipeline. Column-connected membrane separation device. The pump of the invention has the advantages of friendly refrigerant, high water collection quality, no peculiar smell and discharge, and high efficiency and energy saving. It can be widely used in the field of material drying.
