Closed-loop type cold and hot water double-effect drying system

Abstract

The invention relates to a closed-loop type cold and hot water double-effect drying system comprising a cold and hot water unit, a hot water circulation supply system and a chilled water circulation supply system. The hot water circulation supply system and the chilled water circulation supply system are connected with the cold and hot water unit, the cold and hot water unit is provided with a hotwater outlet, a hot water return opening, a chilled water outlet and a chilled water return opening, the hot water circulation supply system includes a unit hot water outlet pipe, a hot water pool, ahot water outlet pipe, a hot water disc circulation water pump, a hot water coil, a hot air fan installed on the hot water coil, a hot water return pipe, a unit hot water circulating water pump and aunit hot water return pipe; and the hot water outlet communicates with the hot water pool through the unit hot water outlet pipe, the hot water pool communicates with a water inlet of the hot water coil through the hot water outlet pipe, a water outlet of the hot water coil communicates with the hot water pool through the hot water return pipe, and the hot water pool communicates with the hot water return opening through the unit hot water return pipe. The closed-loop type cold and hot water double-effect drying system has the advantages of energy saving, environmental protection and efficient drying of articles.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a closed-loop hot and cold water double-effect drying system. Background technique [0002] At present, Hainan betel nut drying adopts a one-to-one method of drying host with air energy heat pump in the drying room, and it is an open-loop drying method. This method is due to the discharge of water vapor generated during the drying process of betel nuts into the atmosphere. , the smell pollutes the ambient air, and at the same time the heat is taken away in the process of draining the steam, resulting in energy consumption. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, a closed-loop hot and cold water double-effect drying system for energy saving, environmental protection and efficient drying of articles is provided. [0004] In order to realize the purpose of the present invention, the present invention adopts following tech...
