Abstract

The invention discloses a baffling dust removal heat pump type drying room. An inner circulating bifurcated fan is arranged in the drying room, and comprises a long shaft and blades. The blades are in a long strip shape, and the sections of the blades are in the shape of a hollow wedge symmetric about the radial direction and center of an impeller shaft. The two ends of each blade are inserted into end discs, and the long shaft is connected and fixed with the end discs through spokes. A draught hood and an air inlet hood are arranged at the two ends of the drying room respectively, the draught hood is connected with an induced draft fan, and the induced draft fan is connected with an evaporator of a heat pump system through a dust remover and then is evacuated. The evaporator of the heat pump system is connected with a main engine through a refrigerant pipe, and the main engine is connected with a condenser through a refrigerant pipe. The air outlet end of an air blower is connected with the air inlet hood through the condenser. The induced draft fan and the impeller of the bifurcated fan are both designed to be of a hollow symmetric structure, and are free of dust accumulation, light, firm and durable. Heat pump cross flow drying and tail heat recovery are especially suitable for being adopted in a low drying temperature system, the nutritional ingredients of thermosensitive substances can be prevented from being damaged, and efficient drying, dust removal and heat recovery are completed with low energy consumption through the system.

Description

technical field [0001] The invention relates to a drying room, in particular to a baffle and dust removal heat pump drying room. Background technique [0002] Due to its mature technology, strong adaptability, low operating cost and strong reliability, the hot air dryer is still one of the main preferred equipment for drying materials. If the tail heat can be effectively recovered during the hot air drying process, it will be beneficial to improve Drying efficiency and the realization of energy saving and emission reduction are of particular importance. [0003] The fan is the key equipment of the hot air dryer. The fan is generally a centrifugal fan. The continuous, stable and reliable operation of the fan is very important for the dehumidification and air circulation of the dryer. Because most of the occasions where the dryer is used contain a certain amount of dust , When the fan is working, when the air flow passes through the high-speed rotating fan impeller, due to th...
