In the painting operation of the shipyard, the quality of the work depends largely on the humidity of the air during construction. Because in the painting operation, the relative humidity is too high will often cause dew on the painted surface, and in the dewy surface coating, it will cause corrosion of the material and reduce the effect of the coating. Therefore, in the painting process, the shipyard often uses a rotary dehumidifier for drying treatment.
The use of dehumidifier for drying can improve the overall coating process effect. In order to meet the requirements of air dehumidification all year round, the most commonly used dehumidifier is a rotary dehumidifier with general refrigeration dehumidification equipment. Dehumidification wheel needs high temperature hot air for desorption regeneration, the current conventional dehumidifier is the use of electric heating for regeneration, regenerative heating energy consumption is the main energy consuming parts of the dehumidifier, usually accounting for more than 40% of the system energy consumption. Consuming a large amount of high-quality electrical energy to generate heat causes the disadvantage of energy waste and high operating costs.

  Therefore, in the entire painting process of the shipyard, what should be done as far as possible is to use a rotary dehumidifier for continuous dehumidification to achieve the maximum quality of the painting process and increase the binding force of the coating.
