Description

Printing house dehumidification system

Technical Field

The utility model relates to an indoor dehumidification technical field especially relates to a printing room dehumidification system.

Background

As is known, an air conditioner has a dehumidifying function, but the air conditioner has its limitation in dehumidifying; on one hand, the air conditioner is not suitable for low-temperature dehumidification, on the other hand, the dehumidification capacity of a single air conditioner is limited, and a plurality of air conditioners have large energy consumption and are not suitable for industrial application. Therefore, most of the current industrial dehumidification adopts a rotating wheel dehumidification technology; the dehumidification rotating wheel is composed of high-efficiency adsorption materials; the continuous dehumidification effect is achieved through continuous adsorption and regeneration. The working principle of the dehumidification rotating wheel is that the dehumidification rotating wheel is divided into a treatment area and a regeneration area by a sealing system in the dehumidification section, and the dehumidification rotating wheel rotates slowly at the speed of 8-10 revolutions per hour to ensure that the whole dehumidification is a continuous process. When the processing air passes through the processing area of the rotating wheel, the water vapor in the processing air is absorbed by the moisture absorption medium in the dehumidifying rotating wheel, the water vapor simultaneously carries out phase change and releases latent heat, and the dehumidifying rotating wheel gradually approaches to saturation due to absorbing certain moisture; at this time, the process air becomes dry and hot air due to its own moisture reduction and latent heat release. Meanwhile, in the regeneration area, the other path of air firstly passes through the regeneration heater, then is changed into high-temperature air and passes through the saturated dehumidification rotating wheel after moisture absorption, so that the moisture absorbed in the dehumidification rotating wheel is evaporated, and the dehumidification capability of the dehumidification rotating wheel is recovered; meanwhile, the regeneration air is changed into wet air due to the evaporation of moisture; and then, discharging the wet air to the outside through a regeneration fan. The size of the specific dehumidification area and the size of the regeneration area are determined according to the situation, and pipelines are arranged in a matching way. The normal dehumidification area to regeneration area ratio is 3: 1 and 1:1, part of the system also needs to be equipped with auxiliary cooling air to realize low-temperature dehumidification. Once the arrangement mode is fixed, the proportion is difficult to change, because the corresponding ventilation pipeline is designed according to the proportion of the regeneration area and the initial area in advance, when the ventilation pipeline is changed, the whole pipeline is also changed correspondingly, and the engineering quantity is large. And when auxiliary cooling air is arranged between the areas, the problem of wind cross is easy to occur, so that the dehumidification effect is not as expected.

The following four desiccant wheels 3 are taken as examples to illustrate the working principle of the present invention: as shown in fig. 2, the ratio requirement in the dehumidification area and the regeneration area is 3: 1, the top dehumidifying wheel 3 can be set as a regeneration area, and the rest part is a dehumidifying area; the top is heated and the high air supply quantity is matched to meet the regeneration requirement. When the dehumidification requirement is not high and high energy and time are not needed, the air supply direction of the rotating wheel at the bottom is only required to be changed; the top and bottom desiccant wheels 3 are set as regeneration zones so that the overall zone ratio becomes 1: 1. When the auxiliary cooling is required to be set to achieve dehumidification at the bottom-crossing temperature, the top desiccant rotor 3 is set as a regeneration area, and the right desiccant rotor 3 is set as an auxiliary cooling area; meanwhile, the dehumidification disc 2 is driven to rotate clockwise at a fixed time, and switching regeneration between the areas is completed. After switching, only the corresponding air inlet and outlet are required to be connected into the room or out of the room.
