Clean workshop design and installation: What are the varieties of air ducts? What should the air duct device pay attention to?

Clean workshop design and installation in the decoration construction time need the most many operations, but also need to install a lot of equipment, of which the air duct is the clean workshop construction project need to be equipped with equipment, its role is to exhaust air supply, and different varieties of workshop suitable equipment of the air duct variety is different, so what are the varieties of clean workshop air duct? What should the air duct device pay attention to? Now let's talk about:

What are the varieties of air ducts in the clean workshop

1. Air ducts are mainly used in industrial and construction projects, and the application fields are mainly touched: Electronic industry dust-free workshop purification system, medical food aseptic workshop purification system, hotel hotels, shopping malls, hospitals, factories and office buildings of the central air conditioning system, industrial pollution control with dust, smoke, oil suction exhaust pipe, industrial environment or post comfort with air supply pipe, coal mine gas drainage gas system, coal mine environmental control with the return air system and so on.

2, clean workshop will use air duct material is: galvanized sheet, stainless steel; Glass fiber reinforced plastic and composite materials that may cause dust source pollution during their use are prohibited.

What should we pay attention to in the clean workshop air duct device

1, the plate of the air duct and components should be selected according to the planning requirements, and the cold-rolled steel plate or high-quality galvanized steel plate should be selected when the planning is not required. The construction device of the air conditioning system of the purification workshop should be developed according to the "primary construction procedure of the clean room, and the cooperation progress plan should be strictly carried out according to the plan."

2, the air pipe must not have horizontal joint, as far as possible to reduce the vertical joint. When the width of the bottom edge of the rectangular air duct is equal to or less than 800mm, the bottom edge shall not have longitudinal splicing joints.

3, the splicing of the air duct plate uses a single bite; Single bite is selected for the closed seam of the circular air duct, and vertical bite is selected for the horizontal seam of the curved pipe. The corner seam of rectangular air duct is selected as corner bite, joint corner bite or button bite. It is necessary to apply sealant or stick sealing tape at the above bite seams.

4. The inside appearance of the air duct must be smooth and smooth, and reinforcement frames and reinforcement bars shall not be installed in the air duct.

5, the air duct should be painted according to the planning requirements. When the planning is not required, it is necessary to remove the oil and rust on the surface of the steel plate before brushing, and then brush and paint after boring. The coating should be free from leakage, foaming and bottom exposure.

The joint between the color steel plate, all the gaps between the R Angle and the wall panel and the roof;

The gap between the air conditioning duct, tuyere, high efficiency filter and the wall roof;

The electric power passes through the gap between the maintenance pipe groove and the edge of the opening of the panel roof;

The gap between all switch socket lamps and the color steel plate top surface;

All process, water supply and drainage, maintenance pipe and hole gap;

Gap between glass and frame;

The sealing silicone should be fundamentally arranged in the color plate device, the sanitary conditions are better, and the clean room is unified after complete cleaning and dust removal. Otherwise, the silicone seam is easy to be polluted and black. Within 24 hours after the silicone is done, there should not be a lot of dust operation and water washing on the ground, which may affect the curing and fastness of the sealing silicone.

3, put an end to the one-sided pursuit of decoration, cancel the door frame and only set the door made of general wood, replace the original frame of the door with other, add a wide range of decoration surface, thus destroying the fire protection coating, can not play the fire protection role;

4, the normally open fire door should be regularly tested to see whether its self-sealing control system, door closing device, sequencer, release switch, etc., is easy to use, whether it can play a self-sealing function when the fire occurs, and resolutely prevent the stacking of items at will next to the normally open fire door.
