Heat energy isenthalpy closed cycle variable-load control system

Abstract

The invention discloses a heat energy isenthalpy closed cycle variable-load control system. A waste heat recovery system, a high-temperature heat pump system and a digital vortex variable-load dehumidification system are connected in series, multi-stage cooling and dehumidification are achieved, meanwhile multi-stage heating is achieved, the three systems are fully used for cooperative work, the purpose of deep dehumidification is achieved, meanwhile, the highest air supply temperature is provided, isoenthalpy energy closed cycle is realized, and meanwhile, the three systems work in the optimal and highest-efficiency working interval; according to the control system, due to the fact that the air temperature of a precooler is obviously higher than that of a reheater, when air flows throughthe precooler, a heat pipe working medium in a pipe is changed into a gaseous state from a liquid state, pressure rises, and the working medium is conveyed to the reheater through an air pipe connecting pipe; after low-temperature air flows through the reheater, the heat pipe working medium is condensed in the reheater, the temperature is reduced, the pressure is reduced, and the working medium flows back into the precooler along a liquid pipe connecting pipe; and in this way, energy closed cycle is formed, and system precooling and reheating can be achieved through waste heat recovery withoutconsuming external energy.

Description

technical field [0001] The invention relates to a thermal energy isenthalpy closed cycle variable load control system. Background technique [0002] At present, there are a large number of drying processes in the industrial and agricultural production process, such as tobacco, traditional Chinese medicine, dried fruit, seafood, vegetables, chemical industry, textile printing and dyeing and other industries have a large number of drying processes. A large amount of water vapor needs to be discharged directly during the drying process, resulting in energy waste. At present, the overall drying process in China is backward and the energy utilization rate of equipment is low, resulting in high drying cost and loss of competitiveness. The purpose of the dehumidification-type value-added heat source is to solve this problem. The main purpose is: 1) Energy recycling, recovery and recycling of sensible heat and latent heat in the exhaust gas discharged during the drying process. 2)...
