In many industrial workshops, we often see various ducts, the most common of which are ventilation ducts and smoke exhaust ducts. Their shapes are similar, and some friends who don't know them can't tell them apart. So what's the difference between a ventilation duct and a smoke exhaust duct? What are their characteristics? How to distinguish it? The following answers these questions for everyone, I hope to be helpful. If you have any questions about ventilation, cooling, dust removal, smoke exhaust, etc., please consult. How to distinguish between smoke exhaust pipes and ventilation pipes 1. Different functions Ventilation pipes are metal or composite pipes for ventilation and air conditioning engineering of industrial and civil buildings. They are an industrial and municipal infrastructure to circulate air and reduce the concentration of harmful gases; The smoke pipe is to avoid the harmful substances produced by the facility during production, which will pollute the air in the workshop. It usually collects harmful objects from the exhaust fan or air suction port, and then sends it to the purification equipment through the pipe for treatment. Can be discharged or reused. 2. Ventilation ducts with different uses generally include: purification system return air duct, central air conditioning ventilation duct, industrial air supply and exhaust ventilation duct, environmental protection system suction and exhaust air duct, mine drainage gas pipe, mining rubber coated air duct, etc.; ventilation Pipes are usually used in industry, construction projects, and urban infrastructure; the main purpose of exhaust ducts is to extract air and smoke. The purpose of exhausting smoke from the exhaust pipe is to discharge the indoor smoke and dust to the outside through the exhaust machine. Since the smoke and dust often stick to the pipe, the exhaust pipe needs to be cleaned frequently. Smoke exhaust pipes are widely used, including wind pipe manufacturers including hotels, factories and so on. 3. Ventilation ducts with different materials are classified according to their materials: generally: steel ducts (ordinary steel plates), galvanized sheets (white iron) ducts, fabric ducts, fiberglass ducts, plastic ducts, composite ducts, color ducts Steel sandwich insulation board ventilation pipes, double-sided aluminum foil insulation ventilation pipes, single-sided color steel insulation ventilation pipes, rubber-coated ventilation pipes (such as mining air ducts), mining plastic ventilation pipes, etc.; The material of the smoke pipe is steel pipe (ordinary steel plate), galvanized sheet (white iron) smoke pipe, smoke exhaust pipe fabric air pipe smoke pipe, glass fiber reinforced plastic smoke pipe, plastic smoke pipe, composite material smoke pipe, color steel Sandwich insulation board smoke exhaust pipe, industrial air supply and exhaust smoke exhaust pipe. In the environmental protection system, smoke exhaust pipes are divided into: suction and exhaust pipes, mining gas pipes, mining rubber-coated air ducts, etc. in the central air-conditioning system of industrial and construction workers in factories and office buildings, dust removal, smoke exhaust, etc. for industrial pollution control. Exhaust pipes such as oil suction, air supply pipes for industrial environments or post comfort. What are the points to pay attention to when installing the exhaust pipe 1. The location of the exhaust pipe is particularly important. The shorter the normal pipe, the better, which is not only more beautiful, but also can discharge the oil fume cleanly. 2. Every kitchen such as factories and hotels needs to be equipped with flues, and the flues are also separated by main and auxiliary. The main pipeline is connected to the whole building, while the auxiliary pipeline is independent. Generally, the oil fume in the home will be stored in the auxiliary pipeline first. Inside, and then enter the main ventilation pipe through the hole on the clapboard, so when installing the flue, the auxiliary pipe must be kept well to prevent the occurrence of smoke pouring or smoke.
