排烟通风管道防腐保温怎么处理?

排烟管道在进行输送一般气体的时候,对于黑钢板风道应该要进行除锈或者是刷防锈漆处理,对于含尘气体也就是要注意去进行喷涂防磨损保护层,当周围环境空气湿度上比较大的时候,对于风道外壁来讲的话,也就是需要去做防腐蚀或者是防锈方面的处理。
When the smoke exhaust pipeline carries on the transportation general gas, should carry on the rust removal or brushes the anticorrosion paint processing regarding the black steel plate air duct, regarding the dusty gas also must pay attention to carries on the spraying anticorrosion protective layer, when the ambient air humidity is relatively big, regarding the air duct outer wall, also needs to go. To prevent corrosion or rust prevention.
对于输送高温、高湿气体的镀锌钢板通风管道内壁宜喷刷磷化底漆或者是其他耐蚀涂料。当通风管道输送高温气体或者是低温空气的时候,对于风道外壁应该要注意做好保温(保冷)处理。
Phosphating primer or other anticorrosive coatings should be sprayed on the inner wall of galvanized steel ventilation pipes for conveying high temperature and humidity gas. When the ventilation pipe conveys high-temperature gas or low-temperature air, for the outside wall of the duct should pay attention to do a good job of heat preservation (cooling) treatment.
输送高温气体通风管道的保温目的,点来讲,我们其实也就是要注意,就其在很大的程度上也就是为了防止管道当中空气发生热损失(出现在冬季集中空调系统);另外一个方面来讲的话,也就是为了防止在输送废热蒸汽亦或者是高温气体的时候阻止热量散发到房间当中而使得室温升高,之后也就可以防止人接触风道而出现被烫伤的现象。

The purpose of conveying high-temperature gas ventilation pipes is, first of all, to be aware that they are, to a great extent, designed to prevent heat loss from the air in the pipes (which occurs in winter central air-conditioning systems); and, on the other hand, to prevent the conveying of waste heat vapor, or It prevents heat from escalating into the room when it is a hot gas, and then it prevents people from getting burned by touching the air duct.
在夏季的时候,通风管道往往因为输送气体的温度低于周围环境的空气露点温度,通风管道外壁会产生结露现象。这对于集中空调系统的风道势必会加大冷量损失,同时凝结水滴会出现污染吊顶和墙地面的现象,这时候进行保冷隔热处理措施也就在情理之中了。
In summer, because the temperature of the conveying gas is lower than the air dew point temperature of the surrounding environment, dew condensation will occur on the outer wall of the ventilation duct. This is bound to increase the cooling loss for the air duct of the central air conditioning system, while condensate droplets will pollute the ceiling and the wall surface, so it is reasonable to carry out the cold insulation heat treatment measures.
