It is characterized in that the structure comprises: housing water jacket-this housing water jacket structure includes: the furnace wall steel shell comprises a vertical furnace wall steel shell steel plate, horizontal embedded plates fixedly connected to the upper end and the lower end of the shell plate, and a cooling water jacket fixedly connected to the outer surface of the vertical furnace wall steel shell steel plate; the embedded water jacket is a copper flat water jacket and is positioned at the upper end and the lower end of the horizontal embedded plate of the shell water jacket and is arranged in a contact manner. The utility model discloses a metallurgical furnace kiln furnace wall cooling device can effectively alleviate furnace charge and flue gas to refractory material erosion, stabilize the furnace wall structure and eliminate the unusual inflation of refractory material and all have better effect, can be used to liquid phase district and gaseous phase district for the erosion scouring force greatly reduced of industry furnace kiln fuse to the furnace wall, the damage degree of furnace wall reduces, corresponding reducible maintenance number of times, improves the whole stove life-span of industry furnace kiln.
Description
Technical field
A kind of metallurgical furnace kiln furnace wall cooling device relates to the Cooling protector of a kind of metallurgical industry furnace gas phase zone and liquid phase region refractory material furnace wall.
Background technology
In the process of smelting process, the refractory material of metallurgical furnace kiln at high temperature receives washing away of furnace charge and flue gas and chemical erosion, can cause the damage of furnace wall, has had a strong impact on stove service life.
Flash stove with the high strength smelting process is an example, and flash furnace reaction tower is made up of furnace roof, furnace wall, and its underpart links to each other with flash stove sedimentation basin, and the furnace wall of flash furnace reaction tower was provided with horizontal water jacket in the past; Because the working region inclement condition corrodes, washes away fierceness, furnace wall is often become into the zanjon shape by erosion; Almost by burn through, make the flash stove can not ordinary production at this zone refractory material, cause maintenance cost high; Furnace service life is low, and the use amount of Copper Water Jacket is big, and production cost is high.
Summary of the invention
The purpose of the utility model is exactly the deficiency that exists to above-mentioned prior art; A kind of degree of injury that can effectively reduce furnace wall is provided, reduces maintenance cost, improve furnace service life; Reduce the use amount of Copper Water Jacket, the metallurgical furnace kiln furnace wall cooling device that reduces production costs.
The purpose of the utility model realizes through following technical scheme.
A kind of metallurgical furnace kiln furnace wall cooling device is characterized in that its structure comprises:
Shell water jacket-this shell jacket structure for water comprises: vertical furnace wall outer steel shell steel plate, be fixed in the Shell Plate top and bottom horizontal insert plate, be fixed in cooling jacket on the vertical furnace wall outer steel shell steel plate outer surface;
Embedding water jacket-this embedding water jacket is a par cover made of copper, is positioned at the horizontal insert plate of shell water jacket two ends up and down, and setting contacts.
A kind of metallurgical furnace kiln furnace wall cooling device of the utility model, it is characterized in that vertical furnace wall outer steel shell steel plate and the horizontal insert plate of described shell water jacket is affixed after, its section is " worker " type.
A kind of metallurgical furnace kiln furnace wall cooling device of the utility model; It is characterized in that described embedding water jacket grows the horizontal insert plate of shell water jacket at the burner hearth medial extremity; Partly be step-like platform at embedding water jacket upper and lower surfaces to the body of heater exterior wall, and the horizontal insert plate of shell water jacket cooperates connection with the recessed step-like platform in embedding water jacket surface for recessed.
A kind of metallurgical furnace kiln furnace wall cooling device of the utility model is characterized in that the shell water jacket is that adjacent many groups are provided with embedding water jacket.
A kind of metallurgical furnace kiln furnace wall cooling device of the utility model; Can effectively alleviate furnace charge and flue gas to refractory corrosion, stablize furnace wall structure and eliminate the unusual expansion of refractory material better effects is all arranged; Can be used for liquid phase region and gas phase zone, make the industrial furnace fused mass reduce greatly the water eroding and flooding power of furnace wall, the degree of injury of furnace wall reduces; The corresponding maintenance times that reduces, the whole stove life-span of improving industrial furnace.

The specific embodiment
A kind of metallurgical furnace kiln furnace wall cooling device, its structure comprises: shell water jacket-this shell jacket structure for water comprises: vertical furnace wall outer steel shell steel plate 1, be fixed in the Shell Plate top and bottom horizontal insert plate 2, be fixed in cooling jacket 3 on the vertical furnace wall outer steel shell steel plate outer surface; Embedding water jacket 4-this embedding water jacket is a par cover made of copper, is positioned at the horizontal insert plate of shell water jacket two ends up and down, and setting contacts.
During use, be adjacent setting with embedding water jacket with the shell water jacket, inboard at kiln, by the vertical furnace wall outer steel shell steel plate of shell water jacket, horizontal insert plate with embed in the space that water jacket forms and refractory material 5 is set, the formation furnace brickwork using.
During operation,, feed cooling fluid with embedding in the water jacket, furnace brickwork using is carried out the solid cooling at the shell water jacket by the turnover mouth of pipe 6,7.
Embodiment 1
The furnace wall of flash furnace reaction tower.Flash furnace reaction tower is made up of furnace roof, furnace wall, and its underpart links to each other with flash stove sedimentation basin, and (adopt the horizontal copper water jacket, refractory material adopts the chromium and magnesium brick refractory material, and the shell water jacket adopts the molten steel cover to embed water jacket.The chromium and magnesium brick refractory material that refractory material adopts adopts 2 to 7 layers of chromium and magnesium brick refractory material according to the thermograde of reaction tower in the flash stove; Reaction tower top low-temperature space adopts 6 to 7 layers of chromium and magnesium brick refractory material; Warm area adopts 3 to 5 layers of chromium and magnesium brick refractory material in the reaction tower middle and upper part; 2 to 3 layers of chromium and magnesium brick refractory material are adopted in high-temperature region, reaction tower middle part; 3 or 4 layers of chromium and magnesium brick refractory material are adopted in reaction tower bottom portion high-temperature region, and promptly the flash smelting furnace reaction tower adopts the cooling device of 10 layers of circular ring type structure, and it is 7 layers, 5 layers, 4 layers, 3 layers, 2 layers, 2 layers, 2 layers, 3 layers, 4 layers, 4 layers from top to down that its refractory material adopts the chromium and magnesium brick refractory material number of plies.Use makes flash stove fused mass reduce greatly the water eroding and flooding power of furnace wall, and the degree of injury of furnace wall reduces, corresponding minimizing maintenance times, and the whole stove that improves the flash stove can reduce the use amount of Copper Water Jacket in the time of the life-span, reduce the reaction tower cost.
