Description

An air heat pipe heat recovery energy saving dehumidification system

Technical field:

The utility model belongs to the technical field of dehumidification systems, in particular to an air heat pipe heat recovery energy-saving dehumidification system.

Background technique:

In an industrial production environment with low humidity requirements, a drying wheel dehumidifier is generally used to achieve dehumidification. The rotor of the rotary dehumidifier is divided into a dehumidification treatment area and a regeneration treatment area. The treated air (humid air) to be treated is sent into the dehumidification treatment area by the fan, and the moisture in the air is absorbed by the hygroscopic desiccant in the dehumidification treatment area, thereby obtaining a dry air flow 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 treatment area of the runner in reverse, so as to decompose and absorb the water in the moisture-absorbing desiccant and take it away, thereby restoring the moisture-absorbing capacity of the moisture-absorbing desiccant, so that the moisture-absorbing desiccant can once again treat the incoming humid air. dry. The entire cycle process is a periodic process of repeated dehumidification and regeneration, thus ensuring a continuous dehumidification effect and obtaining a stable dry air flow.

However, the regeneration treatment area of the rotor needs to be heated to a relatively high temperature to achieve the effect of regeneration, which will inevitably result in high regeneration heating, resulting in high energy consumption, which is a major disadvantage of the traditional dehumidification rotor. At the same time, due to the high temperature in the regeneration treatment area, when the rotor rotates to the treatment area at a certain speed, the heat will be transferred to the treatment air, which will cause the treatment air to have a higher temperature after passing through the rotor, thereby reducing the dehumidification effect of the treatment air .

Chinese patent application number 200810029440.4 discloses a dehumidification system with a rotary wheel, which includes: a rotary wheel whose interior is divided into a treatment area, a regeneration area, and a heat recovery area by a sealing device, and the surface of the rotary wheel has an adsorbent for absorbing moisture ; It is provided with the processing air input pipeline of the pre-cooling coil, and the processing air input pipeline is divided into a treatment branch pipeline connected with the treatment area of the runner and a heat recovery area of the runner when it is close to the runner. A connected regenerative air inlet pipeline; a dry air output pipeline that communicates with the runner treatment area and is provided with a primary cooling coil; a regeneration branch pipeline, one end of which is communicated with the heat recovery area, and the other end is connected with the regeneration Zone connected, the regeneration pipeline is provided with a regeneration heater; and the regeneration discharge pipeline communicated with the regeneration zone, the pipeline is provided with a regeneration cooling coil.

However, there is no heat exchange between the regenerated air and the treated air in the above-mentioned rotary dehumidification system, and the process of heating up the regenerated air and cooling the treated air consumes a lot of energy.

Therefore, it is necessary to provide an improved rotary dehumidification system in order to overcome the shortcomings and deficiencies of the prior art.
