How to realize the energy-saving function of high-speed Yankee hood

The core of the flexibility of the drying optimization and energy-saving technology in the tissue paper machine is the yankee hood, which protects and optimizes the drying environment and ensures product quality through horizontal adjustment and adjustment of air balance. At the same time, the paper quality and drying efficiency are also very high. the drying cost is low, and the quality and drying efficiency of our brand-new Yankee hood and air system paper are also very high, and the drying cost is low.

Our brand-new Yankee hood and air system uses the following technologies to achieve remarkable energy-saving results: 

(1) under all operating conditions, the distance between the hood and the Yankee dryer is kept in an ideal state, and the overall thermal deformation is small: 

(2) High efficient heat transfer of wide-width nozzle box, low operating noise and uniform drying. 

(3) the tailor-made equipment reduces the heat loss and improves the drying efficiency.

This kind of hood is mainly aimed at tissue paper machines with a speed of 1100-1500m/min. The design principle of the hood is to achieve an ideal balance between production capacity and energy consumption as far as possible. 

In order to adapt to the high speed and high output, the hood is designed as a double-in and double-out structure, the hood body is divided into two parts: the dry end and the wet end, each part is composed of suction chamber and expiratory chamber, and the suction chamber is an external cover body. The expiratory chamber is an air blowing system composed of air supply pipes and nozzles. On the Yankee cylinder, the width of the air supply area of the hot air hood is the same as that of paper, and the hood is covered with heat insulation and moisture-proof layer to prevent heat loss and fire.

In the tissue paper machine, the steel Yankee dryer and the hood are used together for energy saving, which can better adapt to the high speed and high quality, save more than 30% of the energy consumption of tons of paper steam, and the overall energy saving effect is more superior, so that the paper mill can save more costs. The profit from the product is also higher. 

It is worth mentioning that the application of modern science and technology will also greatly improve the enthusiasm and efficiency of operators, we should vigorously promote this new energy-saving technology.
