Abstract

The invention discloses a heat pump type tail heat utilizing penetration reverse flow dryer. A draught hood and an air inlet cover are arranged at the two ends of a box of the dryer 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 cyclone dust collector and then emptied. The evaporator of the heat pump system is connected with a main machine through a refrigerant pipe, and the main machine is connected with a condenser through a refrigerant pipe. The air outlet end of an air blower is connected with the air inlet cover through the condenser. A plurality of vertically-arranged flexible separation plates are arranged in the box of the dryer and divide an upper case body and a lower case body into a plurality of units. Through the induced draft fan, the flexible separation plates and axial fans, penetration type reverse flow drying is ingeniously achieved, and work efficiency is improved. Heat pump type tail heat utilization is suitable for heat recovery of low-temperature tail gas, and is particularly efficient and convenient. Through the structure that blades are in a hollow inverted drop shape, dust on impellers is cleaned away in real time, the impeller strength of the fan is increased, stability is increased, safety accidents caused by dust accumulation are effectively eradicated, and the application prospect is wide.

Description

technical field [0001] The invention relates to a dryer, in particular to a heat pump tail heat utilization penetrating countercurrent dryer in which a fan does not accumulate dust. Background technique [0002] People generally refer to drying with a drying temperature below 60 degrees Celsius as low-temperature drying. Low-temperature drying is widely used in the drying of heat-sensitive materials such as crop seeds, Chinese medicinal materials, and biological products. Due to its mature technology, strong adaptability, low operating cost and high reliability, hot air dryer is still one of the first choice equipment for low temperature drying. Low-temperature drying is less likely to utilize tail heat due to the lower temperature of exhaust gas. If the penetration and countercurrent drying of materials can be realized in the hot-air low-temperature drying process, and the tail heat can be effectively recovered, it will be of great significance for improving drying efficie...
