Description
Technical field
This utility model is specifically related to a kind of mist separator of desulfurization flushing water collection device.
Background technology
Wet desulphurization absorption tower is in running, it is easily generated " mist " that particle diameter is 10--60 micron, " mist " does not contain only moisture, it is also dissolved with sulphuric acid, sulfate, sulfur dioxide etc., easily cause staining and heavy corrosion of blower fan, heat exchanger and flue, therefore on wet desulfurizing process, absorption equipment being proposed the requirement except mist, cleaned gas to remove mist before leaving absorption tower, to prevent fouling and corrosion that flue, equipment, chimney are produced.
Current demister pattern usually arranges demister at the top of desulfurizing tower, and demister is mainly made up of fixing devices such as waveform blade, plate, card articles. when the gas containing mist flows through demister with certain speed, inertial impaction effect due to gas, the drop collided when mist and corrugated sheet and gathered arrives greatly the gravity himself produced and exceedes climbing power and when the making a concerted effort of surface tension of liquid of gas, and drop just gets off from separated corrugated sheet surface. the structure that is folded to of demister corrugated sheet adds the chance that mist is captured more, and the mist not being removed is captured through identical effect at next turning, and such repeated action, thus substantially increasing demisting efficiency. the flue gas bending channel by demister, under the effect of inertia force and gravity by the drop separation carried secretly in air-flow out, flue gas after desulfurization flows through demister with certain speed, flue gas is by quickly, change the direction of motion continuously, effect because of centrifugal force and inertia, droplet in flue gas strikes and is captured down on demister blade, droplet collects formation current, effect because of gravity, fall in slurry pool, achieve gas-liquid separation, gas is by after wave-shaped plate demister, it is substantially free of mist, the flue gas passing through demister reaches to remove discharge after mist requires.
In wet desulphurization, the sulfate such as Gypsum Fibrosum can deposit on demister blade, it is therefore desirable to arrange rinse water arrangement and demister is carried out periodic flushing.But, exhaust gas volumn low at boiler load is less than normal, or when cleaner unit have employed low temp. electric dedusting, the water yield of heat smoke evaporation reduces, the fresh water (FW) requirement of desulfurizer reduces, thus affecting the flushing of demister, is easily caused the fouling of demister, blocking.
