Low-grade afterheat recycling type energy-saving dehumidifying unit

Abstract

The invention provides a low-grade afterheat recycling type energy-saving dehumidifying unit which can be used in a high-temperature and high-humidity place. The low-grade afterheat recycling type energy-saving dehumidifying unit comprises a dehumidifying rotating wheel, a first driving mechanism for driving the dehumidifying rotating wheel to rotate, a treatment fan, a regeneration fan, a heat recycling rotating wheel, a second driving mechanism for driving the heat recycling rotating wheel to rotate, a surface air cooler arranged on a treatment air flowing channel, a cooling water tower connected to the surface air cooler and a regeneration heater arranged on a regenerated air flowing channel, wherein treatment air flows through a first treatment region of the dehumidifying rotating wheel, a second treatment region of the heat recycling rotating wheel and the surface air cooler in sequence under the driving of the treatment fan to form the treatment air flowing channel; regenerated air flows through a second regeneration region of the heat recycling rotating wheel, the regeneration heater and a first regeneration region of the dehumidifying rotating wheel in sequence under the driving of the regeneration fan to form the regenerated air flowing channel; dehumidifying rotating wheel regeneration is realized by using low-grade afterheat, so that the final air outlet temperature is reduced, and the energy-efficiency ratio of dehumidifying equipment is obviously increased.

Description

technical field [0001] The invention belongs to the field of direct evaporative cooling industry, and in particular relates to a low-grade waste heat recovery energy-saving dehumidification unit. Background technique [0002] Direct evaporative cooling technology is a natural cooling technology, which utilizes the principle of water evaporation and heat absorption, without the need for high-energy-consuming power equipment such as compressors, and is a new type of high-efficiency and energy-saving refrigeration technology. Evaporative cooling requires a large amount of dry cold air. Due to the limitation of the natural environment, this energy-saving refrigeration technology is mostly used in dry areas. In order to better promote this technology in high-temperature and high-humidity areas, a more energy-saving and directly using high Air dehumidification units for evaporative cooling by natural wind in high-humidity areas become necessary.
