Fan filter unit with static pressure box

Abstract

The invention provides a fan filter unit with a static pressure box, and belongs to the technical field of air filtering equipment. The fan filter unit comprises the static pressure box device and a fan filter device which communicate with each other through an adapting pipe. The static pressure box device comprises a static pressure box body, a placing frame and an initial-effect filter which arearranged in the static pressure box body, and a filter net and a net cleaning mechanism which are arranged on the placing frame; and the fan filter device comprises a filter box body connected with the adapting pipe, a fixing frame arranged above the filter box body, a mounting cover covering the fixing frame, a sealing assembly mechanism, a sealing fixing mechanism, a fan body, a flow guiding structure and an efficient filter, wherein the fan body, the flow guiding structure and the efficient filter are arranged in the filter box body and sequentially arranged in the wind direction flow direction. The ventilation amount is ensured, meanwhile, the noise intensity can be effectively reduced, the air flow exhaust of an air outlet is uniform, the combination of the static pressure box deviceand the fan filter device has the characteristics of high stability and sealing property, and the silencing effect in the operation process of the fan filter unit is ensured.

Description

technical field [0001] The invention relates to the technical field of air filtering equipment, in particular to a fan filter unit with a static pressure box. Background technique [0002] In the ventilation system of construction projects and air-conditioning projects, the static pressure box is widely used. Its main function is that the speed of the air entering the static pressure box is obviously slowed down, the sound of the wind is reduced, and the static pressure box converts the dynamic pressure of the air into static pressure. So that the wind blows farther and the air volume is distributed more evenly. The fan filter is also one of the key equipment of the ventilation system. It is a self-powered air supply filter device, referred to as FFU in English, a modular terminal air supply device with filtering effect; its main function is to pass the air through the top. It is sucked and filtered by HEPA, and the filtered clean air is evenly sent out at a speed of about ...
