Description
Technical field
The utility model relates to electronic workshop heating and ventilating discipline process gases system regions, in particular to a kind of exhaust chimneys.
Background technique
The exhaust gas that various properties can be generated in electronic workshop production process at present, there is an acid waste gas, alkaline exhaust gas and general
Hot waste gas etc..These exhaust gas pass through the process gases processing system of workshop, finally by smoke stack emission into outside atmosphere environment.
Chimney is circle, and diameter is designed by discharge amount of exhaust gas, not of uniform size.Chimney generally uses stainless steel material to make, and passes through flange
Connection, the chimney lining anti-corrosion material of acid or alkaline exhaust gas.Chimney is mounted on outdoor, bottom landing or the indoor row with low layer
Gas air hose is directly connected to, and top is opened wide, and is vented outwards.The temperature of the different types of exhaust gas generated in electronic workshop production process
Degree, humidity are all different.Acid and alkalinity exhaust gas temperature is generally 20 DEG C or so, relative humidity 80% or so.General heat is useless
Temperature degree is 30 DEG C, relative humidity 30% or so.Acid low with alkaline exhaust gas temperature, humidity is big, chimney metal material, heat transfer
Fastly.Surface temperature is at 20 DEG C or so.In summer, outdoor temperature is high, when humidity is big, since chimney surface temperature is low, when outdoor big
The meeting when dew-point temperature of gas is higher than 20 DEG C, chimney outer wall can condense, and generate condensed water, atmospheric dew point temperature is higher, condensation water quantity
It is bigger.Condensed water can flow to ground along chimney, or by dripping on chimney, cause ground moist.If chimney does not land, directly
It is connect with the indoor air hose of low layer, condensed water can flow into interior along bottom duct, flow on wall, influence built-in and indoor ring
Border drops on electrical equipment, may cause electric short circuit accident.Chimney surface moisture can be to the surface of chimney, flange and spiral shell
Bolt forms slow corrosion, influences the beauty and service life of chimney.In winter, outdoor temperature is low, due to the acid inside chimney
Property and alkaline exhaust gas temperature it is high, humidity is big, when outdoor temperature is lower than the dew-point temperature of exhaust gas (about 16 DEG C), inner wall of stack
On can condense, atmospheric temperature is lower, and condensation water quantity is bigger, most of condensed water because gravity flow into chimney bottom, from chimney bottom
Drainpipe excludes.Partial condensation water can discharge opposite direction to exhaust gas and flow into exhaust pipe system, cause air hose part ponding, need
Drainage arrangement to be installed in bottom duct, the risk for bringing draining to leak.In addition, can be by high speed there are also sub-fraction condensed water
Exhaust airstream takes chimney out of, causes throat drift ice phenomenon, causes throat moist nearby, long-play causes throat to become rusty
Erosion can have icing in throat when winter low temperature, hang Ling Xianxiang.General heatrejection is relatively high, and humidity is lower, in exhaust gas
Without corrosive substance.So under normal circumstances without acid and alkaline exhaust condensation water problems outwardly and inwardly.
Existing chimney can not avoid the water problems that condenses and condense well, can only be by keeping the temperature, installing drainpipe, bottom
The methods of installation waterproof tray passively goes to solve this problem, but condensed water still can generate, and be unfavorable for good building ring
The maintenance in border is unfavorable for the protection of electrical equipment, is unfavorable for the anti-corrosion protection of metal chimney.
