A flue gas treatment system and treatment process of a polymer waterproof coiled material production line

Abstract

The invention discloses a flue gas treatment system of a polymer waterproof coiled material production line and its treatment process, comprising a flue gas collection hood, a smoke exhaust pipe, and a side-by-side washing and filtering tower and a decomposition tower installed above the waterproof coiled material production line , the top of the flue gas collection hood communicates with the lower air inlet of the washing and filtering tower through the exhaust pipe, and the upper air outlet of the washing and filtering tower communicates with the lower air inlet of the decomposition tower through the smoke pipeline. The air outlet is provided with a discharge chimney, a negative pressure induced draft fan is provided on the smoke pipeline near the lower air inlet of the decomposition tower, a cooling water pipeline is laid along the smoke exhaust pipeline, and a cooling water pipeline is laid along the smoke pipeline. To clean the water pipeline, a cooling nozzle is arranged in the cooling water pipeline, and a cleaning nozzle is arranged in the smoke pipeline. The invention can collect, wash, filter, oxidize and decompose the flue gas during the production of the polymer waterproof coiled material and discharge it into the air, which is environmentally friendly and pollution-free.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment of waterproof coiled materials, in particular to a system for treating flue gas of a polymer waterproof coiled material production line and a treatment process thereof. Background technique [0002] Polymer waterproof membrane is a kind of building material commonly used in building construction. In the construction of roads, bridges, tunnels, roofs or other buildings that need waterproof and anti-seepage, waterproof membranes need to be laid in advance. The production of polymer waterproof membrane mainly uses raw materials such as modified asphalt waterproof materials, and carries out preparation processes such as stirring and mixing, heating, forming, dipping, coating, sanding and transportation, so as to make asphalt products that meet various process requirements. The mixture is used for production, and a large amount of asphalt fume is continuously generated during the production ...

AI Technical Summary

Problems solved by technology

The traditional treatment method is to collect the oil fume generated, spray and purify the malodorous gas in the asphalt waste gas through simple purification treatment equipment, recover oil and gas condensation, recover dust and dust, decompose and incinerate or absorb the flue gas, and then For high-altitude emissions, such treatment measures are all treated in a one-use-one-standby method, which cannot effectively separate the oil fume, resulting in a high concentration of oil fume, and the smell of the smoke has not been significantly reduced, and cannot fully play the role of purification , still have an impact on the environment and human health
