Efficient air supply fan filter unit (FFU) with humidifying function

Abstract

The invention discloses an efficient air supply fan filter unit (FFU) with a humidifying function, and relates to an air supply device. The efficient air supply FFU comprises a frame, wherein a fan is arranged on the frame, a first partition plate is arranged in the frame, two guide plates are arranged above the first partition plate, a miniature water pump is arranged on the right side of the fan, a water inlet is formed in the miniature water pump, a water pipe is connected to the water outlet end of the miniature water pump, a motor is arranged on the first partition plate, a nozzle is connected to a rotating shaft of the motor, a branch pipe is arranged on the nozzle, and the water pipe communicates with the nozzle through the branch pipe; and a second partition plate is arranged below the first partition plate, a first cavity is formed between the second partition plate and the first partition plate, a filter layer is arranged below the second partition plate, a second cavity is formed between the filter layer and the second partition plate, and an air outlet is formed below the filter layer. The situation that the indoor space is dry due to the air outlet mode of a traditional FFU is avoided, additional arrangement of a humidifier is reduced, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of air filtering devices, in particular to an efficient air supply FFU with humidification function. Background technique [0002] Fan filter unit, the English full name is Fan Filter Unit, referred to as FFU. At present, FFU is widely used in clean rooms, clean benches, clean production lines, assembled clean rooms and local Class 100 applications. It can provide high-quality clean air for clean rooms and micro-environments of different sizes and cleanliness levels. FFU is equipped with primary and high-efficiency two-stage filters. The fan sucks the air from the top of the FFU and filters it through the primary and high-efficiency filters. The filtered clean air is sent out at a uniform speed of 0.45M / s±20% on the entire air outlet surface. Suitable for obtaining a high level of cleanliness in various environments. In the renovation of new clean rooms and clean workshops, the cleanliness level can be i...
