Abstract

The invention discloses a gas engine air source heat pump unit, a drying device, a drying system and a method, which solves the problem of low heat energy utilization in the drying field in the prior art, and has the beneficial effect of improving the energy-saving effect of the heat pump. Specifically The scheme is as follows: a gas engine air source heat pump unit, including an internal combustion engine, a compressor, a condenser and an evaporator connected in sequence, the evaporator is connected back to the compressor, and a flue gas sensible heat recovery device is installed in the outlet flue of the internal combustion engine to absorb the flue gas Sensible heat, the flue gas sensible heat recovery device is connected with the flue gas condensation heat exchanger to further release the condensation heat, the evaporator is set at the air inlet of the heat pump unit, and the flue gas sensible heat recovery device is set at the end of the heat pump unit.

Description

Technical field [0001] The present invention relates to the field of material drying, in particular a gas engine air source heat pump unit, drying device, drying system and method. Background [0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art. [0003] According to statistics, the energy consumption used for drying in some countries accounts for 5% to 20% of the total energy consumption of the country, while the thermal efficiency is only 20% to 60%. Dryer or drying system is the main equipment indispensable in the production process of grain processing, aquatic extruded feed, food industry, has always been one of the equipment with high energy consumption in the process, the main reason is that the need to take away the water by evaporation by heating the hot air after heating the air. [0004] In the past 30 years ago, steam has been a heat source to heat the drying...
