Description
Technical Field
The utility model relates to a high-efficiency demisting device for waste gas treatment, and belongs to the technical field of waste gas treatment.
Background
In the running process of absorption tower and biological trickling filter, it is easy to produce "fog" whose grain size is 10-60 micrometers, and said fog not only contains water, but also contains sulfuric acid, sulfate and sulfur dioxide, etc., at the same time it also can cause contamination and serious corrosion of fan and waste gas pipeline. Therefore, the treatment devices such as the absorption tower, the biological trickling filter and the like provide demisting requirements for the outlet waste gas, purified gas needs to be demisted before leaving the absorption tower and the biological trickling filter, and if demisting is not good, waste gas carrying slurry can be brought to downstream equipment such as a draught fan, a waste gas pipeline and the like, and further blockage is caused, serious vibration of the draught fan is caused, the waste gas pipeline is corroded seriously, scaling and the like, so that the purified gas is forced to be stopped.
The form of current defroster mainly is wire mesh defogging device, blade defogging device etc. and blade defogging device is because the blade surface wall is smooth, and its angle of buckling is limited, therefore also limited to the entrapment effect of liquid drop in the air current, and defogging efficiency is lower relatively. The screen mist eliminator has the advantages of good filtering effect, small-sized liquid drops can be removed, but the screen is easy to block, and the screen is required to be cleaned regularly or a spraying device is installed for spraying or frequent replacement.
Disclosure of Invention
The utility model aims to solve the problems, and provides the efficient demisting device for waste gas treatment, which is used for matching the demisting of the blades with the demisting of the silk screen, has the advantages of small pressure drop and large specific surface area, further improves the demisting efficiency of a demister, fully ensures the gas-liquid separation effect, and reduces the influence on a subsequent waste gas treatment unit.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: a high-efficient defogging device for exhaust-gas treatment, includes the casing and sets up in the inside blade defogging mechanism of casing and silk screen mist removing mechanism, blade defogging mechanism includes blade, slab and card strip, card strip welding is in the casing top, and this card strip bottom is provided with a plurality of draw-in grooves, is provided with the slab rather than the joint in every draw-in groove, the blade slope is fixed on the slab, silk screen mist removing mechanism sets up at blade defogging structure rear the casing bottom is provided with the collecting tank.
The technical scheme of the utility model is as follows:
preferably, the silk screen defogging mechanism comprises at least two silk screens with different specifications, and is detachably connected with two sides of the shell.
Preferably, the silk screen is made of metal wires or engineering plastics, and is woven in a warp-weft mode.
Preferably, the surface of the screen is corrugated.
Preferably, the included angle between the blade and the plate is 120-135 degrees.
Compared with the prior art, the utility model has the beneficial effects that: the utility model uses the waste gas containing partial liquid drops after being treated by acid-base washing or biological drip filter and other equipment containing spraying devices, the waste gas is defogged by a blade defogging mechanism, the gas collides with the blade due to the inertia impact effect of the gas, when the gravity generated by the aggregated liquid drops exceeds the resultant force of the lifting force of the gas and the surface tension of the liquid, the liquid drops are separated from the surface of the blade, the larger liquid drops are effectively removed, the gas passing through the blade still entrains the tiny liquid mist drops, when the gas passes through the silk screen of the silk screen defogger, the mist drops are adhered or adsorbed, and the tiny mist drops agglomerate and coalesce into large liquid drops after repeated absorption of the mist drops, the droplets move downwards along the crossing points of the woven silk screen wires and the wires under the action of gravity, and meanwhile, mist droplets entrained in gas are continuously adsorbed, and the grown mist droplets drop to the bottom of the mist eliminator wire mesh so as to fall down by the gravity of the droplets, and as the particle size distribution range of waste gas particles is very large and even contains submicron-level particles, the wire mesh mist eliminator adopts at least two different specifications of wire mesh, so that the generation of flooding phenomenon is avoided on the basis of guaranteeing interception efficiency, the blade mist elimination and the wire mesh mist elimination are matched, the mist eliminator has small pressure drop and large specific surface area, the mist eliminating efficiency of the mist eliminator is further improved, the gas-liquid separation effect is fully ensured, and the influence on a subsequent waste gas disposal unit is reduced.

Detailed Description
Example 1
This embodiment provides a high-efficient defogging device for exhaust-gas treatment, as shown in fig. 1, including casing 1 and the blade defogging mechanism and the wire mesh defogging mechanism of setting in the casing inside, blade defogging mechanism includes blade 2, sheet 3 and card strip 4, the card strip welding is inside the casing, the draw-in groove joint that sets up on sheet one side and the card strip, the blade slope is fixed on the sheet, contained angle between the two is 135, wire mesh defogging mechanism sets up at blade defogging structure rear, and by phi 0.10mm, phi 0.28mm two kinds of different specification silk screen 5 are constituteed, and can dismantle with the casing both sides and be connected, every silk screen is woven with the longitude and latitude mode by the wire and is formed, its surface is the ripple form, be provided with liquid collecting tank 6 in the casing bottom.
According to the embodiment, the waste gas containing partial liquid drops is treated by equipment such as acid-base washing or a biological drop filter tank and the like and then is defogged through the blade defogging mechanism, the gas and the blades collide due to the inertia impact effect of the gas, the aggregated liquid drops are separated from the surfaces of the blades when the gravity generated by the aggregated liquid drops exceeds the resultant force of the rising force of the gas and the surface tension of liquid, the larger liquid drops are effectively removed, the gas passing through the blades still entrains the tiny liquid drops, when the gas passes through the silk screen of the silk screen defogger, the mist drops are adhered or adsorbed, the tiny mist drops are repeatedly adsorbed for a plurality of times, the tiny mist drops agglomerate and coalesce into large liquid drops, the liquid drops move downwards along the crossing points of the woven silk screen and the silk screen, and simultaneously the mist drops entrained in the gas continue to be adsorbed, the large mist drops drop to the bottom of the silk screen of the defogger, and the particle size distribution range of the waste gas is very large, even particles containing submicron particles are contained, therefore, the silk screen mechanism adopts at least two different specifications, the interception efficiency is ensured, the mist drops are prevented from being generated on the silk screen, the basis of the blade defogging unit is further, the mist defogging unit is fully matched, the defogging effect is further improved, the defogging effect is guaranteed, and the defogging effect is further improved, and the defogging effect is achieved, and the mist drop effect is fully achieved.
