本实用新型提供了一种火法炼锌过滤式冷凝器，属于金属冶炼收集设备，它连接火法炼锌炉，采用过滤收集法使锌蒸汽冷凝为粗锌。其技术方案特点是高温的锌蒸汽从水平通道中进入一个竖向的冷凝竖滤塔下方，在压力作用下上升穿过一个由耐火材料制成的水平过滤层，被过滤层上方的预置液锌层熔汇收集，该设备具有工艺原理合理巧妙，结构合理简单，直收率可高达95％以上；实施成本低廉，可广泛适用于电炉、鼓风炉竖罐对火法炼锌设备。
The utility model provides a fire method zinc smelting filter type condenser, which belongs to metal smelting collection equipment, which is connected with a fire method zinc smelting furnace, and adopts a filtration collection method to condense zinc vapor into crude zinc. The feature of its technical scheme is that high-temperature zinc vapor enters the bottom of a vertical condensing vertical filter tower from a horizontal channel, and rises through a horizontal filter layer made of refractory material under pressure, and the preset liquid above the filtered layer Zinc layer fusion collection, the equipment has reasonable and ingenious process principle, reasonable and simple structure, and the direct recovery rate can be as high as more than 95%.
Description
Technical field
The utility model belongs to the Metal smelting collecting device, particularly relates to a kind of condensation collection device of pyrometallurgy of zinc.
Background technology
Up to the present, collect in the condenser of zinc fume at pyrometallurgy of zinc, having a kind of is the baffle plate type condenser, and it is provided with the polylith plate washer in air flow chamber, by zinc fume circuitous flowing in the polylith plate washer, realizes the condensation recovery.Because the contaminant removal rate is low, the rate of recovery is also low, and the flow process time is long, is eliminated substantially; Another kind is the splash condenser, the principle of work of this condenser is, raise device by stirring of an electric power drive, the high temperature liquid zinc of Zhu Ruing formerly, stir a large amount of liquid pearls of kicking up, make the zinc fume in the continuous absorptive collection pressure chamber of liquid pearl, the process that this liquid collecting absorbs, just like nimbus water vapour, form the process of raindrop.This condenser collection rate is than baffle-type condenser height, and shortcoming is the equipment complexity, needs to consume materials such as a large amount of electric power and graphite rotator, invests huge.Through to China's patent gazette retrieval, do not find this filtering type condenser that the utility model proposes first as yet.
Summary of the invention
In order to overcome and avoid many shortcoming and defect of present pyrometallurgy of zinc, particularly worsen condensation process because of the useless dirt of a large amount of zinc metallurgy waste gas, the purpose of this utility model provides a kind of pyrometallurgy of zinc filtering type condenser, it can make the zinc fume rapid condensation become liquid Zn in the shortest time, obtain the good crude zinc of purity, and realize best condensation efficiency.Its technical scheme is: the zinc fume passage of making a level, its UNICOM is below the perpendicular filter tower of a vertical condensation, the filtering layer that a level of being made by refractory materials is arranged on perpendicular filter tower inner chamber top, the thickness of filtering layer is according to vapor pressure and thickness has different, general 20-50cm is advisable, inlet mouth when condenser, when being connected on the process furnace of working order, the high temperature zinc fume is entered in the pressure chamber of perpendicular filter tower by steam channel, and constantly rise and pass filtering layer, the molten remittance of one deck liquid zinc layer that is seated in the filtering layer top in advance collected; Enclosure wall is arranged above filtering layer one, liquid zinc can not be overflowed, its height is advisable with 5-20cm, in enclosure wall one side, has the overflow port of a potting syrup zinc, and upper end, the hole height of overflow port should be higher than plane 1-2.5cm on the filtering layer; The lower end, hole should exceed plane 0.3-0.5cm on the filtering layer.
This filtering type condenser, the crude zinc purity height of collecting, the rate of recovery can exceed 4-13% than traditional splash condenser rate of recovery 85-94% up to more than 95%.But manufacture craft is simple, need not consume expensive material such as electric power, graphite.And low production cost, it is good to invest little universal performance, a kind of new and effective crude zinc recovery system of can yet be regarded as.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model (front view)
Fig. 2 is Fig. 1 vertical view
In the accompanying drawings, each label component names is: 1 inlet mouth, 2 horizontal channels, 3 slagging-off cabinets, 4 perpendicular filter towers, 5 overflow ports, 6 liquid zinc layers (just putting during production), 7 enclosure walls, 8 filtering layers, 9 zinc smelting furnaces (only expression and condenser refining coupled position)
Embodiment
Referring to Fig. 1, Fig. 2 makes a pyrometallurgy of zinc condenser, and it is by a horizontal steam channel (2), with vertical filter tower (4) communications and liaison mutually that erect.Be equipped with the filtering layer (8) of a level of being made by refractory materials on perpendicular filter tower (4) top, the perpendicular filter tower (4) in filtering layer (8) top has enclosure wall (7) all around.Go up at filtering layer (8) on enclosure wall (7) one sides of top, plane, have an overflow port (5), the interior emptying aperture upper limb of overflow port (5) is apart from filtering layer (8) upper horizontal plane 2cm.The endoporus lower edge is apart from filtering layer (8) upper horizontal plane 1cm.At perpendicular filter tower (4) one side-lowers an active slagging-off cabinet (3) is arranged, when it is closed, can seal with perpendicular filter tower (4) sidewall.Can conveniently remove lime-ash during unlatching.When the electric zinc furnace (9) of the inlet mouth (1) of condenser and working order mutually during communications and liaison, can realize condensate recovery liquid zinc.
Other technical parameter: enclosure wall (7) is gone up plan range 10cm, filtering layer (8) thickness 25cm apart from filtering layer (8).
Claims (2)
1, a kind of pyrometallurgy of zinc filtering type condenser, it is characterized in that: it is by the vapour passage (2) of a level, with the perpendicular filter tower (4) of vertical direction communications and liaison mutually, be fixed with the refractory materials filtering layer (8) of one deck level on perpendicular filter tower (4) top, have enclosure wall (7) in filtering layer (8) top, on enclosure wall (7) side of filtering layer (8) top, have an overflow port (5), at perpendicular filter tower (4) one side-lowers, be provided with the slagging-off cabinet (3) that to open or to close.
2, pyrometallurgy of zinc filtering type condenser as claimed in claim 1 is characterized in that, described filtering layer (8) thickness is 20cm-50cm, and upper end, described overflow port (5) hole should be higher than filtering layer (8) and go up plane 1-2.5cm; Overflow port (5) lower end, hole should be higher than filtering layer (8) and go up the plane, and 0.3-0.5cm, enclosure wall (7) should be higher than filtering layer (8) and go up plane 5-15cm.
