Description

Technical field:

[0001] The utility model relates to the field of alloy material production, in particular to a cooling sedimentation bin for recovering high-temperature tail gas from silicon-manganese smelting. Background technology:

[0002] Alloy, in a broad sense, refers to a product that is added to molten iron as a deoxidizer, element additive, etc. during steelmaking to give the steel certain characteristics or meet certain requirements. An intermediate alloy composed of iron and one or several elements, mainly used in steelmaking. In the steel industry, all intermediate alloys used for steelmaking, whether containing iron or not (such as silicon-calcium alloy), are generally called "ferroalloys". It is customary to also include certain pure metal additives and oxide additives.

[0003] In the production of ferroalloy materials containing silicon and manganese, the high temperature of the silicon and manganese smelting leads to high exhaust gas temperature. The exhaust gas also contains small particles of recyclable materials. In order to ensure the rational utilization of resources and maximize the utilization, most of them are equipped with bag filters and sedimentation bins.

[0004] Sedimentation bin is a common pollutant treatment equipment, which mainly separates and adsorbs pollutants through physical and chemical methods to achieve the purification effect.

[0005] However, as mentioned above, the temperature of the exhaust gas is high. During the recovery process, the high temperature may cause damage to the equipment and cause great difficulties in the use of the filter bag. Therefore, a structure that can ensure the cooling of the exhaust gas is needed to solve the above problem. Utility model content:

[0006] The utility model aims to provide a cooling sedimentation bin for recovering high-temperature tail gas from silicon-manganese smelting.

[0007] The utility model is implemented by the following technical solutions:

[0008] A cooling settling bin for recovering high-temperature tail gas from silicon-manganese smelting comprises a settling bin, a guide plate is fixedly installed in the settling bin, a settling zone is arranged in the settling bin, a plurality of diversion holes are evenly and fixedly arranged on the guide plate, a plurality of connecting pipes are arranged on both sides of the settling bin, a cooling pipe is fixedly connected between two corresponding connecting pipes, a plurality of connecting pipes on one side pass through the corresponding diversion holes, an air inlet pipe is fixedly connected to one side of the top of the settling bin, and an exhaust pipe is fixedly connected to the other side of the top of the settling bin.

[0009] Preferably, a sealing cover is fixedly embedded in the top of the sedimentation bin, and a plurality of groups of obstruction plates are fixedly connected to the bottom of the sealing cover, each group of obstruction plates has a plurality of obstruction plates, each group of obstruction plates extends into the corresponding cooling zone, and each obstruction plate is arranged at an angle.

[0010] Preferably, sealing rings are fixedly connected to both sides of the sedimentation bin, and locking bolts are screwed on the sealing rings.

[0011] The advantages of the utility model are as follows: when the tail gas settles in the settling zone, each group of connecting pipes forms a passage with the corresponding cooling pipe, thereby achieving the effect of auxiliary cooling, so that the tail gas can maintain a normal temperature and avoid overheating. At the same time, when the gas enters the settling zone, the space suddenly increases, so that the flow rate of the gas slows down, so that the gas passes through multiple diversion holes evenly, thereby slowing down the gas flow rate, so that the cooling pipe can fully exchange heat with the degradation liquid in the settling bin, ensuring the best heat exchange effect. Description of the drawings:

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 It is a side view of the guide plate in the utility model;

[0014] Figure 3 It is a side view of the cooling pipe in the utility model.

[0015] In the figure: a sedimentation bin 1, a guide plate 2, a diversion hole 3, a connecting pipe 4, an air inlet pipe 5, a sedimentation zone 6, a cooling pipe 7, a sealing cover 8, a baffle plate 9, an exhaust pipe 10, and a sealing ring 11. Specific implementation method:

[0016] like Figures 1 to 3 As shown, a cooling sedimentation bin for recovering high-temperature tail gas from silicon-manganese smelting comprises a sedimentation bin 1, a guide plate 2 is fixedly installed in the sedimentation bin 1, a sedimentation zone 6 is arranged in the sedimentation bin 1, a plurality of diversion holes 3 are evenly and fixedly arranged on the guide plate 2, a plurality of connecting pipes 4 are arranged on both sides of the sedimentation bin 1, a cooling pipe 7 is fixedly connected between two corresponding connecting pipes 4, a plurality of connecting pipes 4 on one side pass through the corresponding diversion holes 3, an air inlet pipe 5 is fixedly connected to one side of the top of the sedimentation bin 1, and an exhaust pipe 10 is fixedly connected to the other side of the top of the sedimentation bin 1. When working, the tail gas enters the sedimentation zone 6 along the air inlet pipe 5, and is discharged from the guide plate 2. The left side of the plate 2 is the sedimentation zone 6, and the right side of the guide plate 2 is the cooling zone. In this way, multiple connecting pipes 4 are used to connect with the heat exchange pipes respectively. When the exhaust gas settles in the sedimentation zone 6, each group of connecting pipes 4 forms a passage with the corresponding cooling pipe 7, thereby achieving the function of auxiliary cooling, so that the exhaust gas can maintain a normal temperature and avoid overheating. At the same time, the gas enters the sedimentation zone 6. Due to the sudden increase in space, the flow rate of the gas is slowed down, so that it passes through multiple diversion holes 3 evenly, thereby slowing down the gas flow rate, so that the cooling pipe 7 can fully exchange heat with the degradation liquid in the sedimentation bin 1, ensuring the best heat exchange effect.

[0017] A sealing cover 8 is fixedly embedded in the top of the sedimentation bin 1, and multiple groups of obstruction plates 9 are fixedly connected to the bottom of the sealing cover 8. Each group of obstruction plates 9 has multiple obstruction plates, and each group of obstruction plates 9 extends into the corresponding cooling interval. Each obstruction plate 9 is arranged at an angle, which further enables the exhaust gas to directly contact the cooling pipe 7 during the sedimentation process, thereby achieving the best heat exchange effect. At the same time, multiple groups of obstruction plates 9 can be easily replaced and repaired, thereby improving maintenance efficiency.

[0018] Sealing rings 11 are fixedly connected to both sides of the sedimentation bin 1, and locking bolts are screwed on the sealing rings 11. The sealing rings 11 can ensure the sealing of the connection of the connecting pipe 4 and ensure that the whole can be used normally.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
