Deduster.Its maximum temperature used is at 220 DEG C or so, if temperature is higher, dust-removal cloth-bag will be burnt out.However, chemical industry,
Caused dusty gas is mostly the high temperature dust gas that temperature is more than 300 DEG C in the industrial productions such as oil, metallurgy, electric power, cement
Body, to meet that just the temperature of dusty gas is first dropped to less than 200 DEG C by needs for the temperature in use of dust-removal cloth-bag, this needs to increase drop
Warm technological process.In addition, often fluctuation range is larger for its temperature of caused dusty gas in industrial production, even in design cloth bag
Control temperature is considered during deduster, also unavoidably causes burning bag, dust-removal cloth-bag filtration inefficiencies etc. because temperature is too high suddenly
Problem.It is opposite, at temperature too low (being less than 100 DEG C), local gas sharp temperature drop in sack cleaner, in gas
Moisture separates out, so as to produce dew condensation phenomenon.Wherein, when condensation is that the temperature of dusty gas is less than dew-point temperature, dusty gas exists
The phenomenon of condensation liquid on body surface in contact.Wherein dew-point temperature is also known as dew point, is that meteorology middle finger exists
Under fixed air pressure, contained vaporous water reaches saturation and condenses into the temperature be down to required for aqueous water in air.In addition, work as
The humidity of dusty gas is too high or too low dew condensation phenomenon also occurs.Condensation will cause sack cleaner paste bag occur and filter
