1. Improved drying efficiency：Combining the contact drying and convection drying of the paper web, the use of high temperature and high speed hot air makes the hot air produce a rapid convection heat transfer to the paper, while destroying or reducing the thickness of the air film on the interface, thus greatly increasing the heat and mass transfer coefficient, strengthening the evaporation, which is 4-10 times higher than the drying capacity of the ordinary drying cadres, and can greatly improve the yield of the paper machine and the drying efficiency of the dryer.

2.Improve paper quality：In the production of toilet paper, the loose thickness and softness of paper can be significantly improved.

3.Heat recovery and utilization：The water vapor with heat generated by the Yanke hood can be recycled by related devices, such as for power generation, so as to improve the utilization rate of energy and reduce the waste of resources.

1.Installation and debugging：During installation, it is necessary to ensure that the gas hood and Yanke cylinder and other equipment are matched accurately, ensure that the components are firmly connected, and prevent loose, leakage and other problems during operation. After installation, strict debugging should be carried out to make the parameters of the hood, such as temperature, wind speed, wind direction, etc., meet the production requirements.

2.Temperature control：According to different paper production process requirements, the hot air temperature in the hood is precisely controlled. High temperature may lead to excessive drying, brittle and even burnt paper, affecting the quality of paper; If the temperature is too low, the desired drying effect cannot be achieved and the production efficiency is reduced.

3.Temperature control：Reasonable adjustment of the air speed in the hood, the wind speed is too large may make the paper in the drying process of flapping, tearing and other problems, the wind speed is too small will affect the drying efficiency and quality.

4.Scheduled maintenance: Regularly clean the dust and debris inside the hood to prevent it from affecting the flow of hot air and heat transfer effect. At the same time, it is necessary to check the sealing performance of the gas hood and replace the damaged seals in time to ensure the good operation of the gas hood. It is also necessary to check and maintain the heating elements and ventilation equipment of the gas hood to ensure that they work normally and extend the service life of the equipment.

5.Safe operation: The operator must be professionally trained and familiar with the operating procedures and safety precautions of the gas hood. When the hood is running, do not open unnecessary access doors or operating Windows to prevent hot air burns. At the same time, it is necessary to ensure that the environment around the gas hood is safe and there are no flammable, explosive and other dangerous goods.
