Description
(1) technical field: the utility model belongs to the design and manufacturing technology field of non-ferrous metal pyrometallurgy equipment.
(2) background technology: the perpendicular jar of zinc metallurgy is the nucleus equipment in the pyrometallurgy of zinc enterprise.Having perpendicular jar of zinc metallurgy now is on the basis of original American and Britain, the perpendicular jar of moral zinc metallurgy, updates to grow up.China now basically forms Zn-40, perpendicular jar of the serial zinc metallurgy of specifications such as Zn-60, Zn-100.Perpendicular jar of this kind structure is adopted pure indirect heating to the zinc metallurgy raw material, and tank skin is thick, and resistance to heat is big.For improving raw material reduction and the temperature of evaporating in the tank body, must improve the temperature of combustion chamber, strengthen fuel consumption.Heat in the perpendicular jar combustion chamber can only be passed to tank body from one side, and a large amount of heat energy looses from another side and consumes in air, and thermo-efficiency is not high enough.The common drawback that this kind structure is perpendicular jar is: cost and running cost height, general middle and small scale fund can not satisfy builds required input; Though reduce, but still the difficult environmental protection standard that reaches increasingly stringent with other pyrogenic process equipment comparison environmental pollutions; The actual recovered rate is desirable not enough in addition.
(3) summary of the invention:
The purpose of this utility model provides a kind of cost and running cost is low, discharging can reach environmental protection standard, and high " the low high-recovery environmental protection and energy saving zinc metallurgy equipment that drops into " of the rate of recovery, perpendicular jar of promptly a kind of new zinc metallurgy.
Structure of the present utility model is as follows: the end opening of the vertical tank body of an inner lining refractory is to being connected to the gasification section of hollow and inner lining refractory, the end opening of gasification section is to being connected to a water jacket combustion chamber, the bottom of water jacket combustion chamber is provided with the water-cooled dreg discharging roller, the top of tank body is provided with opening for feed, the zinc fume outlet, gas inlet, below, water jacket combustion chamber is provided with slag-drip opening, the cross section of tank body be square (rectangle or square), tank body is glued with the combustion chamber in its cross section two opposite side positions, be glued with the air Heat Room outside the combustion chamber again, the combustion chamber communicates with the inner chamber of air Heat Room.
Raw material in the utility model tank body is that indirect heating combines with direct heating, and tank wall is thin, and the thermal conduction resistance is low, so the combustion chamber working temperature can be lower than 1300 ℃, still can guarantee a jar intravital normal working temperature.This not only saves refractory materials, because the combustion chamber working temperature is low, also can reduce the selection condition of refractory materials, reduces fabrication cost greatly.Carbon in the residual residue behind the distilled zinc; in water jacket combustion chamber internal combustion; form the carbonic acid gas of comparatively high temps and the mixed gas of part carbon monoxide; rise to the gasification section and pyritous carbon reacts; obtain the pyritous CO (carbon monoxide converter) gas; raw material in the jar is heated and protects zinc fume, do not make the zinc fume oxidation, thereby improve the rate of recovery, reduce fuel consumption.The combustion chamber is glued with the air Heat Room, having reduced the combustion chamber to greatest extent looses and to consume in airborne heat, the combustion exhaust that the air Heat Room utilizes the combustion chamber to discharge heats air, air and coal gas through heating burn in the combustion chamber, the temperature height, can reduce gas consumption and consumption of coal, and reduce and build stove brick and insulating brick consumption.
The utility model has the advantages that cost and running cost are low, discharging can reach environmental protection standard, rate of recovery height.

Fig. 2 is the A-A sectional view among Fig. 1.
Fig. 3 is the diagrammatic cross-section of embodiment 2.
(5) embodiment: see following examples.
Embodiment 1: see Fig. 1 and 2.One liner contains the end opening of vertical tank body 1 of 87～95% SiC refractory brick to being connected to the gasification section 2 of hollow and liner unselected clay refractory brick, the end opening of gasification section 2 is to being connected to a water jacket combustion chamber 3, the bottom of water jacket combustion chamber 3 is provided with water-cooled dreg discharging roller 4,5 is opening for feed among Fig. 1,6 are the zinc fume outlet, 9 is blast pipe, and 10 is slag-drip opening.The cross section of tank body 1 is rectangle.Tank body 1 respectively is glued with a combustion chamber 7 in position, its cross section rectangular two long limit, and a long limit of each combustion chamber 7 is glued with an air Heat Room 8 again.11 are the air Heat Room 8 interior vertical air passages that are built into by hollow brick.
Embodiment 2: see Fig. 3.The cross section of tank body 12 still is a rectangle, respectively is glued with a combustion chamber 13 in its position, two long limits, is glued with a common air Heat Room 14 in a homonymy minor face position of two combustion chambers 13.
Use above-mentioned the utility model embodiment equipment; be equipped with custom-designed feedstock production technology and relevant device again; and zinc condensation retrieving arrangement; coal-gas producer; coke oven; heat recovery heat exchanger; sack cleaner; alkalescence wet cleaner etc.; the actual use shows; compare with existing zinc vertical retorting; the fixed capital input reduces by 40～50%; production cost reduces by 15～20%; product recovery rate reaches 92～96% (product recovery rate of general pyrometallurgy of zinc is up to 80%); environmental protection benefit is good; the valuable metal content concn of jar slag of arranging improves 20%, is convenient to the recycling of valuable metal.The water of whole process of production is used for sealing and cooling, for closed circulation is used, and except that a small amount of vaporization losses, unmatchful outer discharging.Production site is with fresh air, and smog such as nothing is yellow, white, black have only a spot of water coolant steam to occur.Externally fume amount is less than 60 milligrams/cubic metre in the useless flue gas of discharging during production, and the SO2 quantity discharged is lower than 40 milligrams/cubic metre, and the NOx quantity discharged is lower than 400 milligrams/cubic metre, and the quantity discharged of carbon monoxide is atomic, can ignore.Jar more perpendicular jar minimizing 20% of institute's residue of arrange.This equipment scale is changeable, and according to various conditions, smallest size can be built and be produce 500 tons on a zinc or a kiloton per year, and also can build is scales such as 10,000 tons, 20,000 tons, is particularly suitable for the middle and small scale fund and implements.
