Embodiment 1

[0022] The present invention is an air source heat pump drying system that can operate independently, such as figure 1 As shown, it includes a compressor 1 and a material box 9, the outlet of the compressor 1 is connected to the inlet of the high-temperature condenser 2, the outlet of the high-temperature condenser 2 is connected to the inlet of the gas-liquid separator 3, and the outlets of the gas-liquid separator 3 are respectively It is connected with the inlet of the low-temperature condenser 4 and the second throttle valve 7, and the outlet of the low-temperature condenser 4 is connected with the first throttle valve 5 and the outdoor evaporator 8 in turn, and the outlet of the second throttle valve 7 is connected with the outlet of the dehumidifier 6. The inlet is connected, the outlet of the outdoor evaporator 8 is connected to the outlet of the dehumidifier 6 and connected to the inlet of the compressor 1, the compressor 1 is connected to the fuel generator 10, the fue...

Embodiment 2

[0028] The difference with Embodiment 1 is: for the area fully covered by the grid, the electrical equipment in the heat pump drying system can be directly driven by the grid, therefore, the fuel engine 10 and the exhaust gas heat exchanger 11 are not provided, and the dehumidifier (6), The low-temperature condenser (4), high-temperature condenser (2) are arranged in sequence according to the air flow direction, and one, more or all of the high-temperature condenser 2, low-temperature condenser 4, and dehumidifier 6 are equipped with fans as required.

[0029] The high-temperature and high-humidity air discharged from the air outlet of the material box 9 first flows through the surface of the dehumidifier 6 and releases heat. The low-temperature and low-pressure gas-liquid two-phase refrigerant gas in the dehumidifier 6 absorbs heat and becomes a superheated refrigerant gas. The dehumidifier 6 The temperature of the outside air drops, and the water vapor in it condenses into li...

Abstract

The invention discloses an air source heat pump drying system capable of operating independently. The air source heat pump drying system comprises a compressor and a material box. An outlet of the compressor is connected with an inlet of a high-temperature condenser. An outlet of the high-temperature condenser is connected with an inlet of a gas-liquid separator. An outlet of the gas-liquid separator is connected with an inlet of a low-temperature condenser and an inlet of a second throttling valve. An outlet of the low-temperature condenser is sequentially connected with a first throttling valve and an outdoor evaporator. An outlet of the second throttling valve is connected with an inlet of a dehumidifier. An outlet of the outdoor evaporator is connected with an outlet of the dehumidifier and connected with an inlet of the compressor. An air inlet and an air outlet are formed in the two sides of the material box correspondingly. By means of the air source heat pump drying system, the problems that in the prior art, drying equipment is far away from agricultural special product producing areas, and an air source heat pump drying technology cannot fully utilize energy in ambient air and cannot completely recycle heat in waste gas exhausted by a material chamber are solved.

Description

technical field [0001] The invention belongs to the technical field of drying special agricultural products, and relates to an air source heat pump drying system that can operate independently. Background technique [0002] The drying link is an important part of the deep processing of most agricultural special products, and is crucial to reducing post-harvest losses, extending the shelf life of agricultural special products, and improving the quality of agricultural special products. Air source heat pump technology has been applied in the field of agricultural special product drying technology because it can obtain heat energy that is several times higher than the input electric energy and has no pollution to the environment. However, at present, the drying room including the application of air source heat pump technology is often built in a fixed location, far away from most agricultural special product production areas. During the process of transporting agricultural spec...
