Abstract
The utility model provides a horizontal environment-friendly smelting furnace which comprises a furnace body. A seal head is arranged at a pulverized coal inlet end of a furnace body, a smoke sucking hood is arranged at an outlet of a flue, and the lower end of the smoke sucking hood is connected with a cooling pipeline through a flange; a residual smoke hood is further arranged outside the furnace body; a residual smoke pipe is communicated on the residual smoke hood; and the horizontal environment-friendly smelting furnace can solve the technical problem of environmental pollution caused by escaping of smoke gas of the existing smelting furnace in the background technology. The horizontal environment-friendly smelting furnace has the advantages of heat transfer in the furnace, good mass transfer condition, simple discharge of the smelting furnace, self-control of furnace temperature of the smelting furnace, and no environmental pollution.
Description
Technical field
The utility model relates to a kind of smelting furnace, is specifically related to a kind of horizontal environmental protection smelting furnace that is applied to copper lead zinc mixing ore concentrate.
Background technology
Mineral resources are valuable cargo bases of the development of the national economy, although China's main Mineral Resources reserves are abundanter, owing to continually develop, reserves reduces rapidly, and the high-quality mineral deposit is on the brink of to exhaust.The department of China's geological prospecting in recent years finds in succession on ground, southwestern three rivers, it is big to have verified reserves, widespread copper, lead, zinc, silver-colored multi-metal complex sulfuration mineral deposit.How bulk concentrate is handled, two kinds of treatment process of Wet-process metallurgy method and pyrometallurgy method are arranged on metallurgy at present, in the pyrometallurgy processing method, the method that rotary furnace has dropped into the industry operation at present is the ISP method, be referred to as copper-lead zinc again and separate airtight smelting method, because traditional rotary furnace is not an all-sealed structure, flue gas escapes in fusion process, causes environmental pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal environment-protection smelting furnace, and it has solved, and existing smelting furnace exists flue gas to escape the technical problem of contaminated environment in the background technology.
Technical solution of the present utility model is:
The horizontal environmental protection smelting furnace that the utility model provides comprises body of heater, and the coal powder entrance end of described body of heater is provided with end socket, and the exit of described flue is provided with range hood, and the lower end of described range hood is connected with cooling pipe by flange; The outside of described body of heater also is provided with the petticoat pipe of having a surplus; Be communicated with the smoke pipe of having a surplus on the surplus petticoat pipe of described institute;
The lower end of above-mentioned end socket is provided with bracing frame.
Also be communicated with cooling water pipe on the above-mentioned range hood.
The present invention has the following advantages:
1. furnace heat transfer, mass transfer condition are good.Energy-saving and cost-reducing, smelting furnace can the two-way rotation of 360 degree, homogeneous heating, smelting efficiency height.
2. the smelting furnace discharging is simple.Be provided with tilting furnace mechanism, the discharging of can directly tilting, simple to operate, easily control, reduced labour intensity.
3. the furnace temperature of smelting furnace is self controllable.Be provided with attemperating unit, can realize the furnace temperature automatic control of smelting furnace.
4. non-environmental-pollution.Smelting furnace is an all-sealed structure, does not have flue gas to escape in the smelting process, can not cause environmental pollution.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The drawing reference numeral explanation
The 1-body of heater; The 2-end socket; The 3-range hood; The 4-flange; The 5-cooling pipe; The surplus petticoat pipe of 6-; The surplus smoke pipe of 7-; The 8-bracing frame; The 9-cooling tube.
The specific embodiment
Structure of the present utility model is as follows:
The horizontal environmental protection smelting furnace that the utility model provides comprises body of heater 1, is arranged at the end socket 2 of body of heater 1 coal powder entrance end, is arranged at the range hood 3 at flue outlet place, passes through the cooling pipe 5 of flange 4 in the lower end of range hood 3; The outside of body of heater 1 also is provided with the petticoat pipe 6 of having a surplus; Be communicated with the smoke pipe 7 of having a surplus on the surplus petticoat pipe, end socket 2 supports by bracing frame 8; Also be communicated with cooling tube 9 on the range hood 3.
Operation principle of the present utility model is as follows:
Flue gas in the body of heater 1 sucks dust chamber by the effect of the outer air-introduced machine of body of heater from the exit by range hood 3 and cooling pipe 5, owing to contain more lead oxide, zinc oxide dust from the flue gas that comes out.Ash-laden gas flows into surface cooler after the thick dedusting of expansion chamber, carry out meticulous purifying and dedusting at sack cleaner at last.Contain ZnO, PbO dirt that a large amount of subparticle shapes exist in the flue gas, because of its surface area is big, active good, dust-precipitator owing to there is proper reaction conditions, following desulphurization reaction: ZnO+SO will take place in flue gas
2+ 1/2O
2=ZnSO
4With PbO+SO
2+ 1/2O
2=PbSO
4Make and enter sulfur in smoke and further removed.Therefore, still not a kind of device that reclaims dust in the flue gas of dust collecting system simultaneously, also is to play certain desulfidation.To adding water in the flue gas cover, play the effect of cooling by water pipe? the hinge fitting that also is provided with in cooling pipe 5 lower ends can rotate freely flue gas cover.
In order not make surplus cigarette enter atmosphere, be provided with end socket 2 at the coal powder entrance end of body of heater 1, in order to eliminate the surplus cigarette in the body of heater 1,, externally get rid of through excess enthalpy smoke pipe 7 under the effect of air exhauster, thereby reach the effect of dedusting by being arranged on the surplus petticoat pipe 6 of body of heater 1 outside.
Its technology is to add furnace charge earlier, i.e. (copper-lead zinc batch mixing) is after the intensification, at first isolate zinc fume and enter with furnace gas, lead-splash condenser gets zinc, isolates the lead bullion (sending electrolysis) that contains metal ingredient after heating up again, all the other are the matte slag, send airtight blast furnace to purify and obtain matte.
