Device includes wall 12, sparge pipe 5 and headstock gear 7, and described headstock gear 7 is placed across inside wall 12, by wall 12
Space be divided into upper and lower two parts, respectively purify chamber 4 and waste residue storage chamber 6, the liquid outlet of described sparge pipe 5 is located at and purifies chamber
In 4, it is filled with liquid in described purification chamber 4, the gas outlet of described flue dust ingress pipe 2 is located under the liquid level purifying chamber 4, described useless
Magnet 9 is provided with the outer wall of slag storage chamber 6, the bottom of described waste residue storage chamber 6 is provided with slag-discharging valve 8.
When the insufficient pressure of flue dust, increase aerator 1, flue dust is blown into purification chamber 4.
Described headstock gear 7 is dividing plate or valve.When headstock gear 7 is dividing plate, wall 12 can offer one
Carefully stitch, for inserting dividing plate or taking out dividing plate, thin seam meeting leak, this is normal, does not affect the use of the present invention.Fill when opening and closing
Put 7 be valve when, being turned on and off by valve, control headstock gear 7 keying.
The quantity of described depurator is multiple, is 4 in Fig. 1.
Described magnet 9 is electromagnet or permanent magnet, and when magnet 9 is permanent magnet, during energising, magnet 9 adsorbing metal makes
It makes metal will not run everywhere in the space in depurator against the inwall of waste residue storage chamber 6, increases what metal recovery was collected
Efficiency.
In described purification chamber 4, pyrometric scale is installed, purifies the temperature of intracavity so as to gradually reduce the temperature of flue dust for monitoring
Degree, increases safety.
The peephole 13 that observation purifies chamber 4 internal state is provided with described wall 12, for observing the liquid in depurator
The position of body is it is ensured that the flue dust that flue dust ingress pipe 2 is passed through can be passed through in liquid.
The detection hole 14 that detection purifies chamber 4 composition of gases within is provided with described wall 12, purifies intracavity for detection
Gas componant.
Connection is provided with described wall 12 and purifies chamber 4 and extraneous pulverized limestone ingress pipe 15, pulverized limestone ingress pipe 15 is used
In adding pulverized limestone, the flue dust purifying is purified again, and the water that pulverized limestone and sparge pipe 5 spray is combined, make the water be in
Alkalescence, is conducive to the purification of flue dust and the recovery of metal.
After flue dust enters first depurator, do not processed, obtained flue dust by detecting hole 14 and pyrometric scale measurement
Composition, content and temperature etc..When flue dust from first depurator out, enter back into second depurator, using water and Calx
The purification of powder, the particulate matter in flue dust is absorbed, is removed, and meanwhile the temperature of flue dust reduces.Via detection hole 14 and high temperature
Table detection obtain the data such as composition, content and the temperature of flue dust, with untreated first depurator in flue dust composition, contain
Amount and temperature data are compared, and its result is able to verify that the purpose of this process: purify.Particulate matter in flue dust progressively exists
It is recovered in each depurator, pulverized limestone mainly makes to be changed into alkalescence etc. containing acid flue dust, accelerate the purification effect of flue dust
Really, until the particulate matter in flue dust obtains fully erased process, meet discharge standard.
Embodiment 2
The present invention also provides a kind of method purifying flue dust, and step is to open headstock gear 7, then makes magnet 9 have suction
Draw the ability of metal, so that electromagnet is energized, or outer wall permanent magnet being put into waste residue storage chamber 6；Flue dust is imported net
Change in the liquid in chamber 4, flue dust is purified after emerging from liquid；After flue dust is imported a period of time, close and open and close dress
Putting 7 makes purification chamber 4 and waste residue storage chamber 6 be relatively isolated, and so that magnet 9 is left the outer wall of waste residue storage chamber 6 or make magnet 9
Lose magnetism, open slag-discharging valve 8, the liquid of waste residue storage chamber 6 is derived, the then metal in withdrawal liquid.
Described liquid is water or lime water.
Gas in the flue dust of the present invention only enters the purification chamber 4 in depurator, and purification process can continuously enter
OK, because magnet 9 acts on, in purification process, the metal in flue dust can be adsorbed on the inwall of waste residue storage chamber 6 flue dust,
On the other hand, due to the effect of gravity, metal can enter the lowest part of whole chamber, and the most at first, purifies chamber 4 He
Waste residue storage chamber 6 is connection, and therefore, metal also can enter waste residue storage chamber 6 under gravity；When need reclaim metal
When, closing headstock gear 7 makes purification chamber 4 and waste residue storage chamber 6 be relatively isolated, and the liquid in purification chamber 4 will not enter waste residue and deposit
Storage chamber 6, the purification of flue dust can proceed.Then magnet 9 is made to leave the outer wall of waste residue storage chamber 6 or so that magnet 9 is lost
Magnetic, such metal would not be attached on the inwall of waste residue storage chamber 6, and slag-discharging valve 8 is opened, by waste residue storage chamber 6
Be mixed with metal liquid discharge, reclaim its interior metal.Way of recycling can be: the liquid being blended with metal adds baking
Dry chamber, is dried, and obtains its interior metal.
