    Wall structure for a smelting stack is comprised of a cooling fluid flow pipe membrane layer comprised of a series of vertical, parallel arranged pipes extending between upper and lower manifold members. The pipe membrane completely surrounds a hot zone in the smelting stack. The upper and lower manifolds extend interiorly of the pipe wall membrane to define an alcove in which there is positioned a series of vertically arranged lengths of insulation cladding which are spaced from one another by gaps filled with fire-proof materials. The gaps contain elements of the pipe membrane layer directed interiorly of the pipe membrane. A waste-gas stack may be mounted directly adjacent the smelting stack with a common wall therebetween. The waste-gas stack wall comprises only a pipe membrane. The primary function of the stack wall structure in the waste-gas stack is to remove heat from the waste gases; whereas, the primary function in the smelting stack is to retain heat within the stack and enable the furnace wall structure to withstand the smelting heat. A common wall serves both these functions. Since the load-bearing elements of the wall structure are the pipe membranes, the stack wall structures may be supported in a blast furnace system by suspension from the upper manifold or erection upon the lower manifold.

    (54) MINE THERMAL TREATMENT AND MELTING MATERIAL
    .. .. ..
    The invention relates to mines for heat treatment and smelting of material, such as smelting ore concentrate ..
    A pyrometallurgical furnace is known, in which a fine-grained concentrate is injected with oxygen-rich gas into a shaft for smelting in a suspended state and continuously being burned and melted there in a suspended state. Formed gas, as well as dust, is discharged through the gas outlet shaft adjacent to the smelting mine, while the melt accumulated at the bottom of the smelting, 5 mine and slag under the partition wall that is immersed from above into the melt bath for further processing of the melt and the distance to the slag . If the pyrometallurgical ore concentrate being processed is sulphide, then at a sufficiently high content of sulphide sulfur by burning sul (11) of sulfur, it is possible to produce so much heat that the burning process and melt.
    ki in the melting furnace passed autogennr without additional fuel .1-J.
    In contact with aggressive media, - and also with a hot bath of the melt and slag, the furnace walls must be
     . . 5 is necessarily refractory lined and cooled.
    To do this, it is necessary to supply the furnace wall folded from the refractory bricks with cooling channels and to pass cold water through them. With this solution, embedding the cooling channels in the refractory material causes difficulties; In addition, the refractory material remains a supporting wall element, therefore the furnace is weakened by cooling channels.

    Closest to the proposed essence and the achieved result is a shaft for heat treatment and melting of a material, which contains a device for cooling walls, made of vertical bshx parallel-connected pipes, mustache. .1In the perimeter of the shahgi of the horizontal electron collectors for the supply and removal of the cooler to the pipes, and the C 2j megalall acceptor. At the same time, the solution and the wall of the furnace do not have the required strength} the suspension of the furnace wall thus made for reasons of low strength is practically impossible. The purpose of the proposed device is to increase the efficiency of operation and the mode of the mine. This goal is achieved by the fact that a shaft for heat treatment and melting of a material, containing devices for cooling its walls, is made of vertical, parallel-connected, coarse, installed along the perimeter, horizontal upper and lower shafts, coolers for supplying and discharging a cooler to pipes and a metal slug It is equipped with additional bearing elements in the form of tubular membranes, equally spaced from each other and connected to pipes located along the perimeter. The mine is provided with at least one gas chamber adjacent to its wall, all walls of which are made only in the form of tubular membranes. The shaft is provided with a vertical partition located under its wall adjacent to the single-chamber gas chamber, which forms a settling tank in the metal reservoir and is made of copper or steel with cooling channels. The partition is mounted with the possibility of moving with the help of a supporting cable along guide rollers in the groove of the lower manifold. The shaft is formed by walls in the form of a steam boiler screen, which are simultaneously made as a bearing wall element for a fire installed on the inner side of the screen of the porous lining. In the proposed drive, the carrier element is a wall in the form of a tubular membrane with vertical vertical interconnected interconnected bridges between pipes through which the cooling medium flows parallel to each other, and with its BOTTOM end ends connected to a horizontal lower collector for distributing the cooling medium, and with its upper end — with a horizontal upper collector, and the collectors are designed as hollow bodies; the walls are in the form of a tubular membrane and can protrude into the interior of the shaft; therefore, between the NIE1ShM collector A rum, upper collector and a wall in the form of a pipe memory 96 94 branded form a niche that is lined with refractory material. The walls of the furnace shaft are, thus, the screen of the first boiler, which, due to good contact with the refractory tank, ideally cools it, simultaneously produces steam or hot water and is a non-drying element for the fire-resistant wall of the shaft. Therefore, the wall of the shaft has such high strength, it can be hung on the upper collar, the torus in the form of a tubular membrane is installed on the lower collector. Due to the walls installed in the recesses in front of the tubular membrane, on the inner side of the refractory lining, the heat loss from the inner part, for example, of the smelting shaft to the outside, is small due to the outer side. The smelter pit mold is a tubular membrane and is not lined with refractory, heat transfer from outside to the walls of the smelting shaft. On the contrary, it is high and therefore the outer side of the proposed smelting shaft can simultaneously be used as the walls of a gas mine, in which hot gaseous waste must be cooled as quickly as possible for cleaning purposes. FIG. I schematically shows the proposed smelting mine with a vapor outlet, horizontal section; in fig. 2 is a vertical section A-A in FIG. one; in fig. 3 is an enlarged view of the node I in FIG. 1; | in fig. 4 is a view of a furnace installation (type B in FIG. I); in fig. 5 is an enlarged sectional view BB in FIG. 1 ... A pyrometallurgical furnace which, for example, should serve to melt fine-grained sulfide concentrate of lead ore, has a common body 1, in which a shaft 2 is installed for melting but suspended, a gas outlet shaft 3 and a sump 4 heated by electrical resistance. a vertical smelting shaft 2 is blown from above a sulfide concentrate with a stream of technically pure oxygen. The ore concentrate burns and melts in a smelting mine with instant heating to a high temperature in a fraction of seconds while it is still in the weighing state. The burning of sulphide sulfur, and sometimes other oxidizable components in an oxygen atmosphere, in most cases already gives enough heat to carry out the process of burning and smelting aggressively. The melt is collected in the melt collector 5, while gaseous waste together with the formed dust is discharged upward through the gas outlet 3. In the collector 5, primary slag is formed on the accumulated melt. The melt flows under the lower edge of the vertical, submerged from the top into the molten bath or slag bath, partitions into the sump 4. In the sump 4. The melt with the aid of the coke breeze is restored and gets the opportunity to be separated into lead and the resulting secondary slags, which are separated are produced from sediment. . The surface of the molten bath or the surface of the slag bath has the same level in the melt collector 5 and in the settling tank 4. The maximum level of the slag bath is indicated as 6, and the minimum level of the slag bath is line 7. The partition 8 prevents the gases of the oxidized and reduced zones from being mixed, allowing you to maintain atmospheric independence in both zones. At the correct shaft 2, the bearing element of the shaft walls is a steam train screen, while the piles 9 are made in the vice pipe membrane and are connected to the memo with pipes 10 through which coolant flows, such as water, and they are connected to the horizontal 1GSH1m collector 1-1, and with its upper ends - with a horizontal upper1cm collector 12. Feed water 13 of the boiler goes through tank 14 into hollow collectors 11 arranged like hollow bodies 11 all four walls of the shaft, water is distributed through all pipes Yu of all walls 9, t even from the bottom upwards, the pipes get into the upper collectors 12, which are made as hollow bodies. And from there, in the form of pards, into the steam drum or steam collector 15. The lower 11 and upper 1 collectors protrude from wall 9 into the form of a tube membrane of the mine and thus formed W1sha between A collector 11, a top collector 12 and a wall 9 in the form of a tubular membrane are lined with refractory bricks 16. Into the inner part of the shaft are vertical, mounted on a wall apart from each other, consisting of elements of the wall in the form of a tubular membrane, carrying steggki 1 7 and 18, etc., with the vertical shaft-like niches between the side walls 17, 18, the collector 11, 11. the upper collector 12 and -wall 9 in the form of a tubular diaphragm filled with refractory stowed on top of each other; irpichi 16. The intermediate space between the wall 9 and the side bearing walls 17, 18, on the one hand, and refractory bricks 16, on the other hand, is filled with or refractory material. Each refractory brick 16 is fixed in this way from the sides of the sin and at the same time it is well cooled from these three sides. In the aggregate, the walls of such a mine have high stability, as well as individual refractory bricks, masonry has a longer service life. The outer surface of the wall 9 can still be protected by fire-resistant packing 19. Wall 20 consists of a tubule membrane located above and a melting shaft 2 located inside the refractory masonry, located directly next to the gas outlet shaft 3, the remaining walls of which consist only from walls 9 in the form of pipe membranes, i.e. the gas-carrying shaft has 3 bearing walls- 9, in contrast to the smelting shaft 2, internally - the side is not lined with refractory bricks. The melting mine has 2 heat losses; from the internal parts of the shaft to the walls of the mine are small, in order to take as little heat as possible from the smelting process, the heat transfer from the mine shaft 3 to the cooled mine walls is very high; Since gaseous wastes containing dust must be cooled to be cleaned, the gaooohlazitel connected to the gas outlet must be performed only small or it may not exist at all, therefore wall 20 on its both sides performs two different, necessary tasks. Since, in the proposed shaft, the carrier element of the wall is made in the form of a tubular membrane, then the smelter 2, as well as the gas outlet 3, are suspended on the upper collectors 12 of the walls 9. As shown in FIG. 4, the upper headers 12 are supported on supports 21 and 22. From FIG. 2 it also follows that cTevnca 2O between the smelting shaft 2 and the gas outlet shaft 3, as well as each of the individual walls of the shaft, ends at its lower end with a sump 23, which is suspended with a distance above the maximum Hbnvi melt level bath or level 6 of the slag bath, so that through intermediate prosgransvo between level 6 and collector 23 it is possible to discharge waste gases from smelting mine 2 to gas outlet 3. At the lower collector II, wall 9 in the form of a tubular membrane on the right side of the smelting mine 2 The second shaft 3 is fixed submerged into the bath of the rasplav by the partition 8, which separates the smelting shaft, as well as the gas outlet from the melt-processing settler 4 located in the immediate vicinity. The partitions 8 are located in the groove 24 of the lower collector II of the wall 9. For facilitating its mounting and dismounting the partition in using the guide rollers 25 and 26 connected to it can be moved on the supporting cable 27, which is passed through the longitudinal opening 28 of the diaphragm partition In FIG. 5. The diaphragm septum 8 immersed in a bath of melt or slag is preferably composed of copper or steel and has channels 29 for the cooling means. Claim 4.
