Aiming at the popular vocabulary "dust removal room" in clean engineering, CEIDI Xidi arranged a popular science article to provide certain ideas for the design and construction of dust removal room in the construction of enterprise clean engineering. Various degrees of dust pollution exist in various factories, including some specialized laboratory buildings, such as chemical products, food processing, metallurgy, casting, carbon materials, mechanical processing, building materials, equipment rooms, etc.

In the construction of clean system engineering, a complete dust removal system should include the following processes:

1.Use a dust hood to trap the dusty gas generated during the process.

2.The collected dust-containing gas is transported to the dust removal equipment along the air duct under the action of the fan.

3.Separate the dust in the dust removal equipment.

4.The purified gas is discharged to the atmosphere.

5.Collect and dispose of the separated dust.

Therefore, the dust removal system of industrial buildings is mainly composed of dust exhaust hood, air duct, fan, dust removal equipment, dust conveying device and so on. In other words, the dust removal system is a local mechanical exhaust system that connects the dust hood, fan, and dust removal equipment by the air duct.

According to international practice, the level of dust-free purification is mainly based on the number of particles per cubic meter of air whose diameter is larger than the classification standard. In other words, the so-called dust-free is not 100% without a little dust, but controlled in a very small unit. Of course, the particles in this standard that meet the dust standard are very small compared to our common dust, but for the electronics industry, even a small amount of dust will have a very large negative impact. CEIDI Xidi discusses the relevant knowledge of the dust removal room with you on the design and construction of a data center computer room. The impact of dust on network equipment is mainly manifested in the following aspects. In the national standard "Computer Site Requirements", the following requirements for its cleanliness are set out in the following table:

1. The interior decoration project of the computer room mainly includes the construction acceptance of suspended ceilings, partition walls, doors, windows, walls, floors, raised floors, and other indoor operations.

2. Indoor decoration operations should comply with the relevant regulations of "Code for Construction and Acceptance of Decoration Engineering", "Code for Construction and Acceptance of Ground and Floor Engineering", "Code for Construction and Acceptance of Wood Structure Engineering" and "Code for Construction and Acceptance of Steel Structure Engineering" .

3. The site, materials and equipment should be clean during construction. Concealment works (such as ceiling under the floor, false wall, interlayer) must be dust-removed, cleaned, and checked and accepted by relevant professionals before sealing. The surface layer of the dark place should be kept free of dust, peeling and cracking for a long time , Ground and other decorative materials do anti-static treatment.

4. The cuts where all pipelines pass through the wall in the machine room must be dust-proof, and the gaps must be filled with sealing materials.

5. During the pasting, bonding and other coating construction, the environmental conditions should meet the requirements of the material specification

6. The decoration materials should choose non-toxic and non-irritating materials as much as possible, and choose non-flammable and flame-retardant materials as much as possible, otherwise they should be painted with fireproof coatings.

7. In the lightning protection design of the computer room, because the lightning protection measures and the anti-static measures intersect and interact, how to do a good job in the electrostatic protection of the computer room is also one of the important aspects to be considered in the lightning protection engineering design.

The decoration requirements of this type of computer room are mainly to meet the technical requirements of the computer for the computer room. The decoration art of the computer room is based on the principle of being generous and comfortable, and meeting its technical requirements. The choice of decorative materials should meet the requirements of sound absorption, fire prevention, moisture resistance, deformation resistance, interference resistance and static electricity. After decoration, make the entire computer room soft, transparent and spacious, not depressing, and comfortable. In order to achieve a modern level of decoration and visual effects. The computer system has special requirements for internal temperature, humidity, cleanliness, electromagnetic shielding, anti-static, power supply lightning protection, various grounding, uninterrupted power supply, special lighting and vibration, etc. The computer room decoration project is to meet the computer and system equipment services The requirements of the operating environment; and the electrical system is the power source of all equipment and lighting, plus many weak electronic systems constitute a highly intelligent computer room system. In other words, the computer room ground engineering, wall and column surface engineering, ceiling engineering, door and window engineering, electrical and pipe duct engineering constitute the engineering content of the data room decoration project.
