Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifier steam waste heat recovery and utilization, in particular to a dehumidifier steam condensate exhaust steam recovery and reuse system. Background Art

[0002] In production workshops such as biopharmaceuticals, new energy, and electronics industries, since there are certain requirements for the temperature and humidity of the workshop, a rotary dehumidifier is generally used to control the temperature and humidity of the workshop. The essential component of a rotary dehumidifier is the rotor, which generally includes a rotary dehumidification zone for dehumidification and a rotary regeneration zone for restoring the dehumidification function of the rotor. The working principle of a rotary dehumidifier is as follows: the humid air flows through the rotary dehumidification zone, and the water vapor in the humid air is taken away by the hygroscopic medium on the rotor. After the dry air is processed to meet the production requirements, it is sent to each workshop; the regeneration heater in the rotary regeneration zone heats the outdoor air, and the heated hot air flows through the rotary regeneration zone, dehydrating the hygroscopic medium in the rotor and taking away the water vapor, thereby playing the role of regenerating the rotor. The regeneration heater in the rotary regeneration zone can use steam to heat the air. In this process, a large amount of steam is consumed. The steam after work also has a high temperature of about 90°C. Direct discharge will waste some heat energy. Utility Model Content
