Product Introduction
Denitrification wet dust collector belongs to the environmental protection equipment, in the flue gas channel on the outer wall surface equipped with water jacket container, in the water jacket container containment part of the flue gas channel wall surface equipped with water relief nozzle, in the water jacket container lower side of the contraction part of the inner hole wall surface and the flue gas channel between the outer wall surface with a ring shaped liquid discharge channel, located in the flue gas channel at the lower port of the ring shaped liquid discharge channel is equipped with contraction shape relief spout, into the liquid pipe is installed on the water jacket container This apparatus adopts liquid flushing, inclusion and filter membrane, inverted U-type groove plate combined operation mode, realizing the flue gas desulfurization and denitrification operation integration, with simple structure, perfect function, reliable operation, good operation quality, wide range of application characteristics, especially suitable for thermoelectricity, non-ferrous smelting industry supporting the use of.
Denitrification dust collector as a kind of high-efficiency dust removal equipment, has a very high quality industrial dust removal effect, according to the dust collector gas dust concentration selection: to chapter force, inertia and cyclone dust collector. Generally speaking, the greater the dust concentration in the inlet, the higher the dust removal efficiency, but this will increase the dust concentration at the outlet, so you can't just generalize from the high dust removal efficiency that the dust treatment effect is good, for the venturi dust collector, jet scrubber and other wet dust collectors, to the initial concentration of dust in the initial dust concentration of less than 10g/m is appropriate: for the bagged dust collector, the lower the concentration of dust, the better the performance of the dust removal in the higher initial concentration. Continuous cleaning, pressure loss and emission concentration can also meet the environmental requirements of electric precipitator initial concentration of 30g/m3 or less, without the addition of pre-removal of dust out of the device can be used.
The dust specific resistance of the dust collector should be within the range of 10^4~10^nΩ-cm. Specific resistance of dust with the temperature of the dust gas, humidity, there are great changes in the same kind of dust, between 100 ~ 200 ℃ than the maximum resistance value: if the gas containing small sulfur conditioning than the resistance is reduced. Therefore, in the selection of electric precipitator, need to grasp the specific resistance of dust in advance, give full consideration to the selection of dusty gas temperature and the adjustment of the nature of dusty gas dusty gas temperature on the selection of the impact of 'dry dust removal equipment in principle must be in the dusty gas temperature above the dew point. In wet-type dust collectors, treatment should be carried out at as low a temperature as possible due to evaporation of water and condensation after discharge to the atmosphere. In filter cartridge dust collectors, the temperature of the dusty gas to be treated directly or indirectly should be reduced below the heat-resistant temperature of the filter cloth. The use temperature of glass fiber filter cloth is generally below 260℃, while other filter cloths are between 80~200℃, in the electric precipitator. The use temperature can be up to 400 ℃, to consider the specific resistance of dust and dust collector structure thermal expansion to choose the temperature of dusty gas.
Selection according to the dispersion and density of dust
The dispersion of dust has a great influence on the performance of dust collector, and the dispersion of dust is the same, but there are differences due to different operating conditions. Therefore, in selecting the type of dust collector, the first thing is to grasp the exact dispersion of dust, such as particle size of more than 10vm can be selected cyclone dust collector. In the particle size of more than a few microns below, should be selected electrostatic precipitator, bag filter, and the specific choice, according to the dispersion and other requirements, refer to the commonly used dust collector type and performance table for the initial selection: and then in accordance with the other conditions and the introduction of the type of dust collector and performance to determine the dust density of dust collector dust removal performance has a great impact, the most obvious manifestation of this effect is gravity, inertia and the centrifugal force dust collector. Centrifugal force dust collectors. A common point for all dust collectors is that the lower the packing density, the more difficult it is to separate and capture the dust particles, and the more serious the secondary dust lifting is, so special measures should be taken in operation and equipment structure.
