Novel ventilation energy-saving heat pump rotary dehumidifier

Abstract

The invention discloses a novel ventilation energy-saving heat pump rotary dehumidifier which comprises a dehumidifying runner, wherein an adsorbent is arranged on the dehumidifying runner; the dehumidifying runner is alternately provided with treating regions and regeneration regions; an evaporation cooler comprises a primary water evaporation component and a secondary evaporator; the water evaporation component is a wet film; and the wet film is connected with a water feeder. The invention effectively reduces the energy consumption required by regenerative heating and improves the dehumidifying effect of the treating wind.

Description

technical field [0001] The invention relates to a dehumidification system for generating dry air, in particular to a fresh air rotor dehumidification system. Background technique [0002] The rotary air dehumidification system mainly relies on the rotary wheel to achieve the purpose of dehumidification. A seal divides the rotor into sector-shaped treatment and regeneration zones. The humid air to be treated (processed air) is sent to the treatment area of ​​the rotor by the treatment fan, and the moisture in the air is absorbed by the adsorbent in the rotor, thus obtaining a dry airflow with extremely low relative humidity, and then achieving the purpose of dehumidification. At the same time, the regeneration air is heated and passes through the regeneration zone of the runner in reverse, so as to decompose and absorb the water in the adsorbent and take it away, thereby restoring the moisture absorption capacity of the adsorbent, so that the adsorbent can dry the incoming h...

Problems solved by technology

[0003] However, there are the following deficiencies in the prior art: 1. The regeneration zone of the runner needs to be heated to a higher temperature to achieve the effect of regeneration, which will inevitably result in higher regeneration heating, resulting in large energy consumption. This is a traditional A major disadvantage of the dehumidification wheel; 2. The traditional method of dehumidification uses a refrigerated coil to cool down and dehumidify once, and then dehumidify through a 270° fan-shaped treatment area, while regeneration uses 90° of electric heating or steam heating. ° fan-shaped regeneration area, the temperature required for regeneration is about 120°C, and the energy consumption is relatively high; 3. The condensed water after the evaporator is cooled is directly discharged without recycling; 4. The air volume required by the regeneration system is higher than that of the refrigeration system. The condensing air volume is small, but there is no bypass, but a large amount of air is regenerated, which increases the resistance of the system
