detailed description

Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

In the field of metallurgical technology, the difference between top and side blowing is not only the change in the position of the gun, but the reaction between the two is completely different smelting equipment and processes. For example, in the field of steelmaking technology, the first is the bottom blowing steel, but the later developed top blowing steel is a groundbreaking utility model, which is completely different from the bottom blowing. This is not simply blowing the spray gun from the bottom. It becomes a top blow, but it embodies different methods and conditions. It is a completely different type of furnace and process.

In the field of metallurgical technology, the use of top-blowing technology or side-blowing technology results in different kinetic conditions, melt agitation conditions and reaction mechanism (reaction sequence) of the melt in the furnace.

More specifically, existing tin smelting techniques are based on a process of reduction smelting. However, what equipment is specifically used in practice to achieve reduction smelting is the core issue in engineering applications. The different choices of equipment determine the different technical routes (ie processes) to achieve the reduction smelting process, and the technical route will determine the reliability, feasibility and advancement of technical indicators of industrialization. The choice of the blowing position (ie the installation position of the spray gun) is one of the most basic and core problems in equipment selection and equipment design. When side blowing or top blowing is selected, the structure of the smelting equipment (furnace type), the structure and arrangement of the spray gun are completely different.

It will be apparent to those skilled in the art that a substantially shaped smelting apparatus, regardless of any technical problems, no matter what improvements it makes, that such an improvement is unlikely to change the choice of its blowing position. Thus, variations in the position of the spray gun are not a routine and obvious choice for those skilled in the art.

Moreover, each metal element has unique physical and chemical properties. Therefore, the installation of a metal device and process without creative labor (modification) cannot be used to smelt another metal. For example, the equipment and processes for smelting tin are completely different from the equipment and processes for smelting lead. That is to say, without creative labor (modification), for example, it is impossible to smelt tin using equipment and processes for smelting lead.

A side blowing tinning process according to an embodiment of the present invention will be described below with reference to FIG. As shown in FIG. 1, the side blowing tinning process according to an embodiment of the present invention includes the following steps:

Adding tin-containing material, flux and reducing agent into the furnace cavity of the reaction furnace, and injecting oxygen-containing gas and fuel into the cavity from the side of the furnace cavity to reduce and smelt the tin-containing material and obtain First coarse tin and rich tin slag, and then discharging the first coarse tin; and

Adding a reducing agent into the furnace cavity of the reaction furnace, and injecting an oxygen-containing gas and fuel from the side of the furnace chamber into the furnace cavity to perform strong reduction smelting on the tin-rich slag and obtain a second coarse Tin and lean tin slag, and then the second coarse tin is discharged.

The side blowing tin-removing process according to the embodiment of the present invention can perform reduction smelting and strong reduction smelting in a single side blowing tin-smelting device by performing strong reduction smelting on the tin-rich slag obtained after reduction smelting, that is, can be single-closed The blown tin is realized in the side blowing tin-making apparatus. Therefore, not only the enthalpy of the tin-rich slag can be fully utilized, but also the process of smelting tin can be greatly shortened, the direct yield of the reduced smelting tin can be improved, and the side-spinning tin-smelting process can be simplified.

Therefore, the side blowing tin-smelting process according to the embodiment of the present invention has the advantages of simple process, low energy consumption, high environmental protection, high degree of automation, and high direct yield.

Advantageously, each of the first rough tin and the second coarse tin is intermittently discharged (cavity). Thereby, not only the reduction smelting and the strong reduction smelting can be performed more stably, but also the operation of the side blowing smelting process can be further simplified, the investment can be reduced, the working conditions can be improved, the intermediate slag discharge process can be reduced, and the operating environment can be improved. .

The lean slag can be discharged and then processed in a conventional smelting furnace.

In some embodiments of the present invention, the side-blow tinning process according to an embodiment of the present invention may further include: adding a vulcanizing agent to the furnace chamber, and spraying an oxygen-containing gas and fuel from a side of the furnace chamber And entering the furnace cavity to vulcanize and volatilize the lean tin slag and obtain a waste slag, and then discharge the waste slag.

The side blowing tin-removing process according to the embodiment of the present invention can perform the reductive smelting, the strong reduction smelting, and the vulcanization volatilization in a single side blowing tin-making apparatus by vulcanizing volatilization of the lean tin slag obtained after the strong reduction smelting, that is, The blowing of the tin can be achieved in a single closed side blowing tinning device. Therefore, not only the enthalpy of the tin-rich slag and the lean slag can be fully utilized, but also the process of smelting tin can be greatly shortened, and the furnace can be used in a multi-purpose manner to improve the direct yield of the reduced smelting tin and simplify the side blowing. Tin process.

Therefore, the side blowing tin-smelting process according to the embodiment of the present invention has the advantages of simple process, low energy consumption, high environmental protection, high degree of automation, and high direct yield.

Specifically, the vulcanizing agent may be intermittently added to the furnace chamber, and the waste slag may be intermittently discharged.

Wherein, the tin-rich slag has a tin content of 15% by weight or less, the tin-rich slag has a tin content of 5% by weight or less, and the waste slag has a tin content of 0.3% by weight or less.

In the existing metal smelting process, a tertiary air vent is provided on the side wall of the furnace chamber (the side wall of the furnace chamber is different from the wall of the hood), so that the flammable combustion in the flue gas is utilized by the air delivered from the tertiary vent. Things.

However, after intensive research by the inventors, it has been found creatively that the air can be more fully burned from the side wall of the hood to the vent. In a specific example of the present invention, the side blowing tinning process according to an embodiment of the present invention further includes: conveying air from the side wall of the air outlet of the furnace chamber to the outlet to burn the smoke Combustible. That is, the flue gas may be produced during the reduction smelting, the strong reduction smelting, and the vulcanization volatilization process. Thereby, the combustibles in the flue gas can be more fully burned, thereby further improving the environmental friendliness of the side blowing tinning process.

The oxygen-containing gas has a volume concentration of oxygen of 30% to 65%. That is, the oxygen-containing gas has an oxygen content of 30 v% to 65 v%, and therefore, the oxygen-containing gas is industrial oxygen or oxygen-enriched air.

The reducing agent may be granulated coal. It is generally believed by those skilled in the art that the use of metallurgical coke as a reducing agent can effectively reduce the tin-containing material and the tin-rich slag. After in-depth research and creative labor, the inventor discovered that compared with the reduction of tin-containing materials and tin-rich slag by using metallurgical coke, the reduction of tin-containing materials and tin-rich slag by using granular coal can further reduce the lean slag. The tin content in the tin-rich slag is less than or equal to 5 wt%, so that the direct yield and recovery of tin can be further improved. Therefore, by using granular coal as a reducing agent, technical bias is overcome and costs can be reduced.

Advantageously, the particle size of the granular coal may be less than or equal to a predetermined value.

The fuel may be selected from at least one of pulverized coal, natural gas, coke oven gas, and producer gas.

The flux may be limestone, quartz or a mixture of quartz and lime.
