1. Laying principle of ventilation duct installation system
Pipeline laying shall be clearly installed and concealed, and generally open installation shall be adopted. Because the open installation is convenient for maintenance, the concealed installation method shall be considered when the open installation cannot be adopted. The pipes shall be concentrated in columns as far as possible and laid parallel along the wall or column as far as possible. If the pipe diameter is large or the thermal insulation shall be arranged near the wall. Generally, when two pipes are arranged in parallel, the spacing shall not be less than 100 ~ 200mm.
2. Connection principle of ventilation duct processing system
In the pipeline with welding as the main connection method, a sufficient number of flange connections shall be set, and in the connecting pipeline with thread as the main connection method, sufficient movable joints shall be set to make it cheaper for installation, disassembly and maintenance
3. Support principle of ventilation pipe processing system: the pipe shall not be directly supported on the equipment with the valve, and the support or hanger shall be set separately. The weld of the pipe shall be located at the place where the construction is convenient or the stress is small, and the weld shall not be located at the support and the distance shall not be less than 200mm.
4. If the properties of different dusty gases are different, the subsection treatment of purification should be different.
When there are many pollution sources, they can be concentrated in one purification system or divided into several systems. However, the mixing of pollutants will cause combustion, explosion hazards, gases with different temperatures and humidity. After mixing, condensation, dust or different gas properties in the pipeline will affect the recovery or purification efficiency.
5. The layout of ventilation duct processing system shall ensure that the leakage of the overall system is small and that there is sufficient air volume at the dust suction port.
6. The layout of ventilation duct processing system shall reduce resistance.
In the process of ventilation duct installation, if the installation is not good, it will produce noise, air leakage, unreasonable layout, resulting in pipe waste and other problems. It is said that there are three products and seven installation. Installation is more important than the product itself. It is recommended that you choose an experienced installation team
