Sample device, there is many limitations, especially dustiness for stationary source dioxin sampler common at present greatly, flue dust temperature
Under conditions of height, humidity are big, filter cylinder blocking can be generated, accessory high-temperature expansion causes poorly sealed, humidity is excessive heat exchange is caused to be imitated
The problems such as rate is low, especially in the device for abatement of smoke and dust of exhaust gas dioxin abatement equipment is checked and accepted, according to " state, the People's Republic of China (PRC)
Family's environment protectment protection " requirement, the detection of abatement equipment removal efficiency needs to deduster import and export while sampling,
And entrance is that (before exhaust gas dioxin abatement equipment) dust concentration and temperature are all very high, and the capacity of quartzy filter cylinder is limited,
Under high dirt state, it is easy to cause filter cylinder fully loaded in a short time, so that airway blockage, resistance increases, and causes sampler automatic
Protection, sampling are shut down on the way, cannot keep continuous sampling, therefore the prior art cannot be simultaneously to same before deduster and after deduster
Step is sampled.
Summary of the invention
In view of the above deficiencies, the present invention provides a kind of high-temperature high dust dioxin sampling apparatus, before installing filter cylinder additional
Deduster, by bulky grain sample collection before filter cylinder in the dust arrester of deduster, a small amount of aerosol sample is collected in filter cylinder,
To guarantee that filter cylinder will not be fully loaded with, continuous sampling is kept, completes to detect the synchronous of deduster removal efficiency.
