Drying equipment control method and drying system

Abstract

The invention discloses a drying equipment control method and a drying system. When the dry-bulb temperature in a curing barn is lower than a temperature threshold value and the wet-bulb temperature in the curing barn is lower than a low humidity threshold value, airflow in a main air duct is heated through a first condenser and a second condenser, the temperature in the curing barn is increased, and heat supply and temperature rise of the curing barn are achieved; when the dry-bulb temperature in the curing barn is lower than the temperature threshold value and the wet-bulb temperature in the curing barn is larger than or equal to the low-humidity threshold value, an inner dehumidification circulating fan operates, a dehumidification throttling device is turned on, air flow is dehumidified through the evaporation section of the heat pipe heat exchanger and the inner dehumidification evaporator, the air flow is heated through the condensation section of the heat pipe heat exchanger, a first condenser and a second condenser, so that the dry-bulb temperature and the wet-bulb temperature in the curing barn are increased; therefore, according to the drying equipment control method and the drying system, temperature and humidity control over the curing barn is achieved, heat recovery is conducted on air exhausted by the curing barn through the heat pipe heat exchanger, and the purposes of saving energy and reducing consumption are achieved.

Description

Technical field [0001] The present invention belongs to the field of drying, and is specifically, and is a drying device control method and a drying system. Background technique [0002] With the proposal of carbon-up, carbon neutralization and double carbon objectives, the country is increasingly attaching importance to the promotion of energy conservation and emission reduction. In response to the agricultural product processing industry, the air energy heat pump replaces the coal-fired roast house is gradually promoting national promotion, and is an important measures for national energy conservation and emission reduction. [0003] At present, the air energy heat pump tobacco drying equipment in the industry is usually based on the raw coalbed room. It is replaced by the radical boiler, and the air energy heat pump unit is used. The thermal energy is heated to the roasting house to heat the tobacco; where the baking room is usually borrowed from the original roast room struct...
