TEST CHAMBER FOR EMITTING POLLUTANTS WITH DISTRIBUTION PLATE

摘要

The present invention relates to a distribution plate provided with contaminated emissions test chamber. The invention cap 210 is formed an air discharge channel (215) for discharging the air in the air supply channel 211 and the test chamber to the outside to supply the air into the test chamber; Once in communication vertically downward air discharge pipe 219, the air inside the test chamber is discharged to the air discharge channel (215); The body portion (230) provided by the shape of the both ends of the open tubular shape, such that once the lid portion 210 and closed; Is provided on the inner peripheral surface of the main body 230, the air discharge pipe 219 penetrates as a first distribution plate having an air flow hole 234 is formed so that the inlet air from the air supply channel 211, distributor (233 ); And a first distribution plate 233 is attached to the end of the air discharge pipe 219 is penetrated through the, first being the inner peripheral surface and spaced apart from the main body part 230, provided so that the air flow introduced by the air distribution hole 234, 2 It provides a pollutant emission test chamber having a distribution plate (235). ; Test chambers, pollution, building materials, distribution plate
