Abstract
The utility model discloses a lead-containing material smelting device relates to lead-containing material smelting technical field. The device includes guide structure, when guide structure made the flue gas pass through the sedimentation tank, the flue gas flow direction was the anti-arch type that sinks earlier and then rises. The utility model discloses a device can avoid appearing the problem that the lead-containing smoke and dust glues the wall sintering in the high temperature flue gas at the lead-containing material smelting in-process, has reduced the smoke and dust rate to reduce and return the smoke and dust volume, reduce the energy consumption, save the processing cost.
Description
Technical field
The utility model relates to lead-containing material smelting technique field, relates in particular to a kind of lead-containing material smelting apparatus.
Background technology
The melting technology of traditional lead-containing material mainly comprises step: lead-containing material is mixed with oxygen-containing gas, reductive agent, in reaction tower, carries out cross reaction and reduction reaction with suspended state, and in settling tank heavy sorting layer; The slag flue gas gets into waste heat boiler by funnel uptake, after recovery system.Process unit is as shown in Figure 1, and settling tank 2 is arranged on the below of reaction tower 1, and funnel uptake 3 is arranged on the top of settling tank.Such techniqueflow weak point, serialization, process stabilizing, but dust rate is higher in its production process, is about 10% usually, and funnel uptake and easy sticking wall of cigarette ash and the cigarette ash sintering of taking place of waste heat boiler, will influence ordinary production.
The utility model content
The technical problem that (one) will solve
The technical problem that the utility model will solve is: provide the purpose of the utility model provide a kind of reduce in the lead-containing material fusion process dust rate higher, solve the lead-containing material smelting apparatus that is prone to the sticking wall agglomerating problem of leaded flue dust in the high-temperature flue gas in the production process.
(2) technical scheme
For addressing the above problem, the utility model provides a kind of lead-containing material smelting apparatus, and this device comprises guide frame, and when said guide frame made flue gas pass through settling tank, flue gas flow direction was sink and rise earlier counter-arch shaped.
Preferably, said guide frame is arranged at the settling tank top, and section is V-shaped or counter-arch shaped.
Preferably, said guide frame is the V-shaped or counter-arch shaped settling tank top of section.
Preferably, this device also comprises: air inlet port, be arranged at the settling tank top, and be used in settling tank, spraying into compressed air.
Preferably, said air inlet port be arranged to the vertical direction angle be 15 °-75 °.
Preferably, said guide frame is made up of copper water jacket and refractory materials.
(3) beneficial effect
The utility model device can avoid occurring the sticking wall agglomerating problem of leaded flue dust in the high-temperature flue gas in the lead-containing material fusion process, reduced dust rate, returns fume amount thereby reduce, and cuts down the consumption of energy, and saves tooling cost.
Description of drawings
Fig. 1 is traditional lead-containing material smelting apparatus structural representation;
Fig. 2 is the lead-containing material smelting apparatus structural representation according to a kind of embodiment of the utility model;
Fig. 3-4 is the diagrammatic cross-section of hanging device A-A direction shown in Figure 2.
Embodiment
Lead-containing material melting method and device that the utility model proposes specify as follows in conjunction with accompanying drawing and embodiment.
In traditional lead-containing material melting technology engineering, flue gas autoreaction tower directly goes to the rising flue stream after getting into settling tank, and flue gas flow direction is milder, and most of dust will be taken away by flue gas, and the dust rate of flue gas is higher.According to the lead-containing material smelting apparatus of a kind of embodiment of the utility model, when making flue gas pass through settling tank, flue gas flow direction is sink and rise earlier counter-arch shaped; After flue gas gets into settling tank; Increased downward initial velocity, in addition the dust action of gravity and influence, the dust that can be taken away by flue gas reduces; The dust that rests on settling tank increases, and the feasible dust rate that finally flows to the flue gas of funnel uptake reduces.
As shown in Figure 2; Lead-containing material smelting apparatus according to a kind of embodiment of the utility model comprises: guide frame 4, when guide frame 4 ability flue gases pass through settling tank 2, owing to stopping of guide frame 2; Flue gas flow direction is sink and rise earlier counter-arch shaped; The flue gas that gets into behind the settling tank 2 has increased downward initial velocity, in addition the dust action of gravity and influence, can be reduced by the dust that flue gas is taken away; The dust of staying at the bottom of the settling tank increases, and makes the dust rate of the flue gas that finally flows to funnel uptake reduce.
Shown in Fig. 3-4; Diagrammatic cross-section for hanging device A-A direction shown in Figure 2; Guide frame 2 is hung gradually to press and is formed; Each grade material can be the rectangular parallelepiped of standard, also can be the bottom surface shown in Fig. 4-5 and is the arcual rectangular parallelepiped, and the concrete shape of each grade material should be as the restriction to this device.Because the formation technology of pressure type gradually, the guide frame 2 shown in the figure is unsmooth, and each grade material also leaves corner angle, but along with the use of device, corner angle will be level and smooth by sweep of gases.At this, whether guide frame is smoothly not as the restriction to the utility model device.
In order further to reduce dust rate, this device also comprises: at least one air inlet port 5, be arranged at settling tank 2 tops, and be used in settling tank 2, spraying into compressed air.Preferably, air inlet port 5 be arranged to the vertical direction angle be 15 °-75 °, the flow velocity of compressed air is preferably 20-180m/s, flow is the 0-30% of exhaust gas volumn.
Embodiment
Present embodiment is that example further specifies the utility model with plumbous oxygen enrichment flash stove.
As shown in Figure 2, the flash stove of present embodiment comprises reaction tower 1, settling tank 2, one-level funnel uptake 3.In the flash stove of present embodiment, settling tank 2 tops are set to hang gradually " V " type of pressure, and the top is provided with air inlet port 5, in flash stove settling tank, spray into pressurized air by air inlet port 5, and its flow is 2500Nm
3/ h, gas velocity is 80m/s, when changing the high-temperature flue gas gas flowfield once more, reduces dust content, changes flue dust character, dust rate is 6.5%, and flue dust does not have sintering phenomenon.
Above embodiment only is used to explain the utility model; And be not the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be defined by the claims.
