Description
Technical field
The utility model relates to a kind of protective device of filter, is specifically related to a kind ofly by avoiding filter element formula high-temperature iron removing filter temperature acute variation to protect the protective device for filter element formula high-temperature iron removing filter, and the utility model belongs to protective device field.
Background technology
Externally the large-scale steam power plant of heating generally need to arrange Gateway Station in Heating Network, and it adopts Steam Heating heat supply network recirculated water, the heat supply network recirculated water outward supplying heat after heating, and steam-condensation becomes hydrophobic.Apart from the corrosion of pipeline and heat exchanger, contain a large amount of ferriferous oxide in hydrophobic due to long.The hydrophobic parameter of heat supply network changes to some extent with steam parameter, but 120 DEG C of the general hydrophobic parameter of heat supply network: temperature >, pressure > 0.4MPa, considers energy-conservation requirement, this hydrophobic oxygen-eliminating device that is generally recycled to therrmodynamic system.Because generating set has higher requirement to water and steam quality, this is hydrophobic directly fills into therrmodynamic system and often can not meet the water and steam quality requirement of unit, and need to carry out deironing processing to it, therefore in order to ensure generating set, the water and steam quality of especially overcritical and above unit, need to arrange high-temperature iron removing filter and carry out deironing processing to hydrophobic.
In addition the raising of realizing along with whole society's energy-saving and emission-reduction, more and more extraction steam for factories is hydrophobic need to be recycled to generating set, the temperature and pressure of these condensate water is directly related with the parameter of extraction steam for factories, parameter changes also greatly, exceed 140 DEG C but wherein have a large amount of hydrophobic temperature, also need to arrange high-temperature iron removing filter for this reason.
High-temperature iron removing filter can adopt electromagnetism deironing filter and tubular filter, but the de-ferrous effect of electromagnetic filter is unstable, and cannot remove paramagnetic iron oxide (α-Fe2O3), therefore generally should not select electromagnetic filter, should adopt tubular filter, especially for supercritical unit.
Consider that temperature is higher, tubular type deironing filter need adopt the good filter element of heat resistance, the material such as filter element material is generally does not have leachable or the few carbon fiber of leachable, high-performance organic matter, stainless steel.But reached its retaining power after these filter element operation a period of times, operation pressure reduction increases, need backwash to recover the strainability of filter element.Thorough in order to ensure backwash, filter backwash generally adopts the mode of air water backwash, but due to deironing filter running temperature and pressure higher, if adopt the direct backwash of normal temperature air water will cause that the temperature of deironing filter body and filter element sharply changes, thereby produce very large thermal stress, have a strong impact on the life-span of filter and filter element, even directly cause the destruction of filter element, therefore before deironing filter backwash, must adopt cooling measure.
In addition before the deironing filter after stoppage in transit, backwash puts into operation, also should slowly heat up, otherwise the hydrophobic deironing filter that directly enters of high temperature touches filter element, the thermal stress that can produce because of expanding with heat and contract with cold is equally had a strong impact on to the life-span of filter and filter element, the destruction that even causes filter element.
