Summary of the invention:

Be the protection environment, propose corresponding, practicable environment protection smelting reason equipment is the purpose of this utility model place, testing through a large amount of, in the trial-manufacturing process, the technical scheme of the process furnace in a kind of totally enclosed mercurous waste residue treatment unit is feasible, also be effective, the process furnace that a kind of mercurous waste residue is handled, be characterized in that it comprises: power shaft 10, feed regulator 9, charging bucket 8, spiral propeller 7, well heater 6, mercuryvapour pipe 5, point for measuring temperature 4, lagging material 3, heating furnace body 2 and processing back waste residue gathering barrel 1 each parts are formed by connecting, wherein: the position is at the power shaft 10 of heating furnace body 2 head end end face central authorities, and external power is the 3-5 kilowatt of propulsion source that band slows down; Feed regulator 9 is drawing-in devices of a drive, is installed in the centre of charging bucket 8 and spiral propeller 7, regularly, quantitative reinforced process can control; Charging bucket 8 is sealing drums of the back taper of a steel, is contained in the top of heating furnace body head end, in the bottom of charging bucket 8 feed regulator 9 is housed; Spiral propeller 7, it is one and is connected on cylinder on the axis by long steel disc spiral welding, the spiral propeller circle diameter is that 120-200 millimeter, length are that the helical pitch of 4-8 rice, spiral is the 60-100 millimeter, spiral propeller 7 head ends and 10 coaxial connections of power shaft, terminal in the central connection supporting of heating furnace body 2 terminal bodies of heater; Well heater 6 is thermal source places of this device, it is that the periphery, And that is wrapped in spiral propeller 7 leaves hollow circular electric furnace certain interval, that made by the interior electroporcelain material of wearing nichrome wire, the iron frame that whole electric furnace is made by angle bar is fixed in the body of heater, and furnace power is between 1.5-3 kilowatt; Mercuryvapour pipe 5 is installed in the top of heating furnace body 2, compiles the mercuryvapour that comes by the mercuryvapour arm on well heater 6 walls in the heating furnace body 2 and enters later process; Point for measuring temperature 4 is installed in the top of heating furnace body 2, has 3-5 only, and the probe of each point for measuring temperature directly contacts the waste residue Heating temperature of position; Heating furnace body 2 is shells of whole process furnace, can make drum shape, also can be the rectangular parallelepiped orthogonal, be welded with steel plate, be supported on ground with several seat legs below, around the intravital heating member of stove, fill, generally can select silicic acid sulphur lagging material for use with lagging material 3; Handling back waste residue gathering barrel 1 is to place melt pit for appropriate at the last position , And of being contained in of this device, and end direct and spiral propeller 7 suitable for reading communicates.

Working process of the present utility model is such: pour the some amount of mercurous waste residue into charging bucket 8 And earlier and seal, connecting power supply heats well heater 6, when furnace temperature reaches 500 degrees centigrade as can be seen from point for measuring temperature 4, start spiral propeller 7 and feed regulator 9, make mercurous waste residue slowly, entering in the middle of the blade of the spiral propeller 7 that rotates of control arranged, mercurous waste residue is pushed in stove on one side, on one side in the stirring of rolling, roasting in around the electric furnace again on one side, so in the progradation, mercury in the waste residue constantly is vaporized evaporation, gather by the mercuryvapour arm and to enter mercuryvapour pipe 5, not had mercury when waste residue is advanced to end can evaporate, so it is not mercurous to fall into the waste residue of gathering barrel 1 at last.Can rationally discharge.

The beneficial effects of the utility model are conspicuous, process furnace rational in infrastructure, reliable, the entire treatment process is carried out under sealed state, reach Chu Li Hou And in the treating processes and do not cause new environmental pollution, waste residue after the processing and air all meet discharging standards, can also reclaim heavy metal Hg, and this is a good job of benefiting the nation and the people,, all be a technology that is worthy to be popularized no matter from social benefit, economic benefit fork-like farm tool used in ancient China.

The utility model is if the furnace temperature difference of grasping also can be used for extracting mercury other industrial residues in addition

Description of drawings

Accompanying drawing: the process furnace concrete structure synoptic diagram that the mercurous waste residue of the utility model is handled.

The meaning that each graphical indicia is expressed as follows respectively in the accompanying drawing:
