How to do the purification workshop in the enterprise to achieve the best purification effect

In order to obtain a good cleaning effect, the cleaning workshop should not only focus on reasonable air-conditioning purification measures, but also require corresponding measures in process construction and other professions. Not only must there be a sound design, but it must also be carefully compliant with standard construction and installation. And correct use of clean room and scientific maintenance management. In order to achieve good results in the clean room, many domestic and foreign literatures are expounded from different angles.

In fact, it is difficult to achieve ideal cooperation between different professions, and it is difficult for cleaning shop designers to grasp the quality of construction and installation management, especially the latter. In terms of cleanroom cleaning measures, many designers or builders often do not pay enough attention to the necessary conditions, resulting in unsatisfactory cleanliness. This article briefly discusses the two necessary conditions for achieving the cleanliness requirements of cleanroom measures.

1. Airflow organization:

The airflow organization in a clean room is different from that of an ordinary air-conditioned room, which requires clean air to be sent to the operation site first. Its function is to limit and reduce the contamination of the workpiece. For this reason, these principles should be considered when designing airflow in the clean workshop: minimize eddy currents, avoid introducing pollution from outside the working area into the working area, try to prevent secondary dust from flying to reduce the chance of dust contaminating the workpiece, and the airflow should be as uniform as possible, The wind speed should meet the technical and hygienic requirements, and when the airflow flows to the return air outlet, the dust in the air can be effectively taken away.

2. Air supply cleanliness:

Cleaning Systems System final filters typically use HEPA filters or sub-HEPA filters, and here there seem to be two types of filters to choose from for each cleanliness level, either high performance or low performance, depending on the situation: When the environment is seriously polluted, or the proportion of indoor exhaust gas is large, or the clean room is particularly important, a large safety factor is required.

In either or both cases, choosing a higher type of filter may instead choose a lower performing filter. For cleanrooms that need to control 0.1μm particles, a Class D filter should be selected regardless of the concentration of particles being controlled.

The above is only mentioned from the perspective of the filter. In fact, the selection of a good clean room filter should also fully consider the characteristics of the clean room, the filtering characteristics and the characteristics of the purification system.
