The invention provides a cleaning-room net cover, which is formed by a rigid square outer frame the inside of which is provided with a screen mesh. Air filtering shell fabric pieces with different density can be laid on the screen mesh; the net cover can be in a convex square table shape; a circle of hanging enclosing pieces can be arranged on the edge of a center frame horizontally arranged; and the middle part of the center frame can have no or extremely sparse air filtering shell fabric. The net cover is arranged on a cleaning air outlet in a cleaning-room project, can form ideal cleaning airflow distribution in a cleaning room, concentrates cleaning airflow to blow areas needing to be cleaned, can reduce indoor vortex flow and raise the cleanliness of surrounding air in the room, has the function of preventing the leakage of air filters, and greatly reduces the comprehensive operation cost of the cleaning room.
Description
technical field [0001] The invention belongs to the field of clean room engineering, and relates to a net cover installed on an air outlet in a clean room. Background technique [0002] The existing clean room is equipped with a clean air outlet, and the air outlet is usually covered with a fine wire mesh cover. The mesh cover has a beautiful and slight flow uniformity effect, and the clean air outlet blows out laminar flow of sterile and dust-free air to the required clean area. The clean airflow can dilute and repel the bacteria-containing airflow emitted by the personnel in the clean room, so as to reduce the phenomenon of bacterial dust pollution in the air. In the past, the clean airflow from the clean air outlet often cannot form an ideal airflow organization in the room. In order to improve the required clean area To improve the air cleanliness, the existing method is to comprehensively increase the air flow of the clean air outlet, which consumes a lot of energy, the...
