Method for efficiently transferring heat and mass by utilizing turning wheel and system

Abstract

The invention discloses a method for efficiently transferring heat and mass by utilizing a turning wheel. The method comprises the following steps: distributing A and B gases in a staggered form and then repeatedly exchanging A and B through the rotating turning wheel, wherein the exchanging means transferring for heat or mass or simultaneous transferring for heat and mass. The invention also provides an efficient heat and mass transferring system utilizing the method. The system comprises the turning wheel and two air guide devices; the two air guide devices both at least comprise two sets of channels which are isolated from each other and are arrayed in a staggered form; the channel walls are in tight contact with a ventilating surface of the turning wheel. According to the invention, the efficient heat and mass transferring at low rotating speed can be realized and the reliability of large-size turning wheel can be promoted by reducing the rotating speed.

Description

technical field [0001] The present invention relates to a method and system for heat and mass transfer using a runner, in particular to a method and system for implementing efficient heat and mass transfer by using a runner for multiple exchanges and gas exchanges during one revolution Background technique [0002] As a common mass and heat transfer equipment, rotors have been widely used, including total heat recovery rotors, air heat exchangers, solid dehumidification rotors, VOC adsorption rotors, CO 2 Absorption runners, etc. There are two problems in the application process of the runner. One is the problem of the speed and efficiency of the runner. If the speed is too high, the complexity of the system will often increase, the reliability will decrease, the sealing will be difficult, and the cost and energy consumption will increase at the same time. However, the runner often A certain speed is required. In some applications, such as total heat recovery, the speed has...

Problems solved by technology

There are two problems in the application process of the runner. One is the problem of the speed and efficiency of the runner. If the speed is too high, the complexity of the system will often increase, the reliability will decrease, the sealing will be difficult, and the cost and energy consumption will increase at the same time. However, the runner often A certain speed is required. In some applications, such as total heat recovery, the speed has a significant impact on efficiency. High speed often corresponds to high total heat recovery efficiency.

[0003] The second is the size and speed of the runner. The size of the runner should not be too large. If the size of the runner is too large, the structure will be unstable and the production will be more difficult, especially in the case of high speed. Larger, requiring a larger runner diameter, such as the air preheater of a boiler in a power plant, etc.
