Description

technical field [0001] The invention relates to a dehumidification system, in particular to a dehumidification and air-conditioning system with a rotary wheel adopting heat recovery of heat pipes and enhanced ultrasonic regeneration. Background technique [0002] Dehumidification is an important process of air treatment. For some special industrial production environments (such as low humidity requirements), the rotary dehumidification system is generally used to achieve the purpose of dehumidification. The dehumidification rotor is divided into a treatment area and a regeneration area by a sealing system inside the dehumidification section. The dehumidification rotor rotates slowly at a certain speed to ensure the continuity of the entire dehumidification process. When the treated air passes through the treatment area of ​​the runner, the water vapor in it is absorbed by the hygroscopic medium in the runner, and the treated air becomes dry and hot air due to the reduction o...

Problems solved by technology

Although the above technologies have reduced the energy consumption of the regeneration heater to a certain extent, the energy in the regeneration air (in a state of high temperature and high humidity) at the outlet of the regeneration zone of the runner has not been effectively recovered, so a large amount of energy is still wasted in vain

In addition, the currently used heating regeneration method has the defects of high energy consumption and low energy efficiency. Although renewable energy such as solar energy can be used as the energy source for the regeneration heater, the grade of these energy sources is difficult to meet the regeneration temperature of conventional dehumidification materials (100 degrees above), therefore, ultrasonic regeneration technology has been proposed by some scholars and experts, such as Chinese Patent No. CN200510110441.8, titled "the dehumidification and air-conditioning device for enhanced regeneration and dehumidification by ultrasonic waves", which proposes to utilize ultrasonic energy to dehumidify the desiccant in the adsorption bed. Enhanced regeneration, so that the regeneration temperature of the dehumidifier can be reduced, so that the condensation heat of the refrigeration system can be effectively used

However, the dehumidification and regeneration of the system are carried out alternately, which will inevitably lead to the instability of air dehumidification
