Drying dehumidification and oil-water separation all-in-one machine adopting air source heat pump

Abstract

The invention discloses a drying dehumidification and oil-water separation all-in-one machine adopting an air source heat pump, and solves the problems of high energy consumption and heat waste which prevail in the high-temperature material drying method. The machine comprises a heat preservation drying house in which a humiture sensor is arranged, a heat exchanger which is communicated with the heat preservation drying house through a first return air duct, a condenser communicated with the first return air duct, an electrical heating device connected with the condenser, a blower of which air inlet is corresponding to the electrical heating device and the air outlet is communicated with the heat preservation drying house, and an exhauster of which the air inlet is corresponding to the air outlet of the heat exchanger, as well as a first electrical air door and an evaporator which are sequentially arranged between the heat exchanger and the exhauster, a heat pump circulation device connected with the condenser and the evaporator respectively, an oil-water separator connected with the evaporator, and a controller connected with the humiture sensor, wherein a first air outlet corresponding to the heat exchanger and a second air outlet communicated with the outer environment are formed in the third return air duct. The drying dehumidification and oil-water separation all-in-one machine has a reasonable structure, various functions, and an excellent energy-saving effect.

Description

technical field [0001] The invention relates to a drying machine, in particular to an air energy heat pump drying, dehumidification and oil-water separation integrated machine. Background technique [0002] In our country, high-temperature drying is mainly used in some special material places, such as high-temperature drying of tea, urban sludge, sharp fruits, fertilizers and other products. Commonly used drying methods for high-temperature drying include steam drying, microwave drying, and hot air oven drying. Since the drying of materials must meet at least two conditions: heating and dehumidification, and dehumidification in the process of high-temperature drying will waste a lot of heat, which sometimes accounts for 70% of the total heat. [0003] Specifically, the shortcomings of traditional high-temperature drying methods are mainly manifested in the following aspects: [0004] 1. Steam drying and hot stove drying need to burn a large amount of primary energy suc...
