The quality of smoke exhaust and ventilation ducts is immediately determined by the characteristics of flue gas machines. Good flue gas machines can produce good smoke exhaust and ventilation ducts, and good smoke exhaust and ventilation ducts can have good prices. It is a very logical understanding. The smoke exhaust and ventilation duct is a thick walled prefabricated component made of mixed mortar using alkali resistant and high toughness glass fiber alkali resistant mesh cloth as the raw material. The concrete should be made of fast hardening sulfoaluminate cement or low acidity potassium thiocyanate concrete with a compressive strength grade of not less than 32.5, and coarse sand should be used. The mixture of concrete and sand should be 1, and the wall thickness of the smoke and dust duct should be evenly proportioned. Under the premise of reliable measures to ensure that there are no cracks in the smoke and dust duct during transportation and installation, it is not necessary to choose to increase the bending stiffness of the baffle.

The application of smoke exhaust pipes in Jinan City can promote excellent natural ventilation, promote indoor ventilation in the room, and control the speed of the cyclone to reduce suffocation. What is called natural ventilation? It means that the dirty gas in the room or in the enclosed area is discharged, and the harmful substances caused in the processing plant are cleaned and solved before being discharged outdoors. Then, fresh air is sent into the room to dilute the harmful substances in the liquid gas, Consider everyone's requirements for gases. Ventilation ducts are used for cleaning in purification workshops, for central air conditioning solution system software in pharmaceutical or food industry purification workshops, and for cleaning in hardware factories and their production and manufacturing fields; It can also be used for installation in central air conditioning, such as large and medium-sized shopping venues, some office floors with luxurious indoor decoration, and hotels and restaurants; In industrial production, it can be used in the exhaust system machinery and equipment for cleaning dust and kitchen oil fumes, as well as in the exhaust system of coal mines and the coalbed methane system software for extracting coalbed methane.
