FFU fan rotating speed adjusting method, system, equipment and medium

Abstract

The invention discloses an FFU fan rotating speed adjusting method, system and device and a medium. The method comprises the steps that production process information of production devices of all production areas in an MES system is obtained; whether the product material is in contact with or about to be in contact with the external environment is judged according to the production process information; if so, an FFU fan in the production area where the production equipment is located is controlled to increase the operation speed; and if not, the rotating speed of the FFU fan is dynamically regulated and controlled according to the environmental cleanliness. According to the method, the related production process information capable of reflecting the exposure degree of the product material is obtained from the MES, the rotating speed of the FFU fan is dynamically adjusted according to the exposure degree of the product material through analysis and judgment, the effect of linkage of the MES system and the FFU fan group is achieved, the product quality of dust-free production products is ensured on the basis of ensuring the environmental cleanliness, and the energy is saved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method, system, equipment and medium for adjusting the speed of an FFU fan. Background technique [0002] At present, in the purification production process of organic electroluminescent materials (OLED), the speed of FFU (Fan Filter Unit, fan filter unit) will be adjusted to the maximum, and it will continue to run 24 hours a day, so that the material processing process needs to be in a dust-free environment. Performed in a clean room. [0003] However, the FFU that runs continuously at the maximum speed will consume a lot of energy. This kind of operation does not meet the requirements of environmental protection, and it also increases the cost of product materials, especially for the operation of large dust-free clean rooms. There is a relatively large pressure on the cost of large and spare parts replacement. [0004] In order to solve the above technical problem...

AI Technical Summary

Problems solved by technology

[0005] 1. The space required for the purification and production of organic electroluminescent materials is generally relatively large, and there are different functional areas at the same time. The overall adjustment of FFU needs to be adjusted after all areas are completed, and the reduction in energy consumption is very limited.

[0006] 2. In some steps, the organic material is completely in a closed state, such as the sublimation purification step, the organic material will not come into contact with the outside dust, and turning on the FFC to purify the environment has no actual cleaning effect
