Description

Fan filter equipment based on cleanliness factor dynamic adjustment Technical Field The utility model relates to the technical field of air purification, in particular to a fan filtering device based on dynamic adjustment of cleanliness. Background A Fan Filter Unit (FFU) is a modularized air purifying device integrating a fan and a high-efficiency filter, and is mainly used in environments such as clean rooms, dust-free workshops and the like to provide local or global high-cleanliness air circulation. The filter has the core functions of controlling the concentration of particles in the air through efficient filtration and uniform air supply, and meeting the clean requirements in the fields of precision manufacturing, biological medicine and the like. At present, the conventional FFU generally can only be operated at a fixed wind speed, cannot dynamically adjust the wind speed and energy consumption according to the cleanliness of the environment, and cannot monitor the concentration of particulate matters in the air in real time, so that closed-loop control cannot be realized. And the traditional FFU generally adopts multi-region cooperative control, namely the traditional electric control method has the conditions of response delay and energy consumption waste, and the filtering efficiency verification and system maintenance of the FFU depend on manual detection. In the communication mode, the traditional FFU adopts a wired communication mode, so that the wiring problem exists, and the improvement difficulty of a clean room cannot be increased. Therefore, the traditional FFU has the following problems of energy consumption waste, namely that the traditional FFU adopts a fixed wind speed operation mode, power cannot be dynamically adjusted according to environmental cleanliness to cause cleanliness fluctuation and continuous high energy consumption, the traditional FFU generally adopts single-point monitoring or local control, the states of all areas of a clean room are difficult to comprehensively reflect, local pollution or redundant operation of over-clean areas is easy to occur, and communication and wiring complexity are problems, namely that the communication mode of the traditional FFU depends on wired communication, flexibility is poor, installation and wiring costs are high, and signal stability is easy to influence by electromagnetic interference.
