Description

Technical Field

[0001] The utility model relates to the technical field of smelting dust removal, and more specifically to a device for resource treatment of smelting soot. Background Art

[0002] During the smelting production in a steel plant, high-temperature soot is generated. If these soot are directly discharged into the external environment, it will not only damage the environment, but also waste the heat contained in the soot. Therefore, it is necessary to carry out resource treatment on the smelting soot.

[0003] After retrieval, the existing patent (publication number: CN219603611U) discloses a device for resource treatment of smelting dust removal ash. During its use, by setting a heat exchange flue gas chamber in the evaporation tank, the dust sludge in the filtration tank is in the evaporation chamber, and with the stirring of the stirring blade plates, it absorbs the heat of the sintering flue gas, evaporates the contained water, and realizes the effect of using waste heat to assist in dehydrating the dust sludge, providing convenience for the subsequent recovery and utilization of the sediment sludge, reducing energy consumption, and creating double economic and environmental benefits. However, the inventor found the following problems in the prior art during the implementation of the present utility model: for the above-mentioned treatment device, when treating the smelting soot, the hot soot gas inside the intake pipe is directly introduced into the heat exchange flue gas chamber and the heat conduction pipe, heating the inside of the evaporation tank and the discharge barrel respectively, and then directly flowing into the exhaust pipe and being transported to the next process. However, by adopting such a method, this part of the flue gas flows into the next process without being treated, resulting in incomplete treatment of the smelting soot.

[0004] In view of this, the present utility model proposes a device for resource treatment of smelting soot to solve this problem. Summary of the Utility Model

By providing the stirring motor, the central shaft pipe can be driven to rotate, and then the air outlet disc can be driven to rotate.

Specific embodiments

[0024] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are merely examples. A smelting dust resource treatment device related to the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0025] Referring to Figures 1 to 4 , the present utility model provides a smelting dust resource treatment device, including a treatment tank 1. The inner cavity of the treatment tank 1 contains a treatment liquid. An exhaust pipe 2 is embedded at the top end of the treatment tank 1. A central shaft pipe 3 is rotatably connected to the top of the treatment tank 1. The top end of the central shaft pipe 3 is rotatably connected to an intake pipe 4 for supplying hot flue gas through a rotating sleeve. An air outlet plate 5 is embedded on the surface of the central shaft pipe 3 close to the bottom side. The inner cavity of the air outlet plate 5 is communicated with the central shaft pipe 3. Air outlet holes 6 are formed on the surface of the air outlet plate 5. A slag discharge pipe 7 is obliquely and upwardly embedded in the lower right of the treatment tank 1. The height of the air outlet holes 6 is higher than the height of the bottom opening of the slag discharge pipe 7. A slag discharge assembly is arranged inside the slag discharge pipe 7. A circulating drying assembly is arranged on the surface of the treatment tank 1.

[0026] The slag discharge assembly includes an auger blade 8 rotatably connected to the inner wall of the slag discharge pipe 7. A reduction motor 9 for driving the auger blade 8 to rotate is fixedly installed on the outer wall of the slag discharge pipe 7. The top end of the slag discharge pipe 7 is welded with a discharge chute 10.

[0027] The circulating drying assembly includes a first heat-conducting pipe 11 fixedly installed on the inner wall of the treatment tank 1 and a second heat-conducting pipe 12 embedded in the inner wall of the discharge chute 10.

A pump body 13 for driving the heat-conducting liquid to circulate between the first heat-conducting pipe 11 and the second heat-conducting pipe 12 is fixedly installed at the end of the first heat-conducting pipe 11.

[0028] When the utility model is in use, the overall device is pre-connected to an external power control system. The external smelting soot is transported from the air inlet pipe 4 to the air outlet disc 5 through the central shaft pipe 3, and then discharged from the air outlet holes 6 to be mixed and contacted with the treatment liquid inside the treatment tank 1. The air after the treatment liquid adsorbs the soot slowly floats inside the treatment liquid and then is discharged from the exhaust pipe 2, completing the soot treatment process.

[0029] Furthermore, during the process of treating the soot with the treatment liquid, the heat in the soot heats the treatment liquid, and then the heat is transferred to the inside of the heat-conducting liquid by heat conduction. The pump body 13 circulates and transports the heat-conducting liquid inside the first heat-conducting pipe 11 and the second heat-conducting pipe 12 to conduct and utilize the heat. When the reduction motor 9 drives the auger blade 8 to rotate and discharge the solid slag from the discharge chute 10, the discharge chute 10 is heated by the heat-conducting liquid, and the solid slag can be assisted in drying by using the waste heat when sliding, which is convenient for subsequent recycling of the solid slag.

[0031] It should be noted that by setting the stirring motor 14 and controlling the start of the stirring motor 14 by an external controller, the central shaft pipe 3 can be driven to rotate, thereby driving the air outlet disc 5 to rotate. When the air flow is discharged from the air outlet holes 6, the air outlet position can be continuously changed, thus improving the contact effect between the air flow and the treatment liquid.

[0032] The number of the air outlet holes 6 is several, and several air outlet holes 6 are evenly arranged on the surface of the air outlet disc 5.

[0033] Furthermore, by setting the number of the air outlet holes 6 to be several, when the smelting soot air flow is discharged from the air outlet holes 6, the air flow can be divided into small bubbles, thereby improving the contact treatment effect between the air flow and the treatment liquid.

[0034] A plurality of stirring rods 15 are arranged on the surface of the air outlet disc 5 in a circumferential array.

[0035] Furthermore, by providing the stirring rod 15, the rotation of the air outlet plate 5 drives the rotation of the stirring rod 15, and the stirring rod 15 can break up the large air bubbles floating inside the treatment liquid into small air bubbles, thereby further enhancing the contact treatment effect between the airflow and the treatment liquid.

[0036] A plurality of arc-shaped pushing plates 16 are fixedly installed on the surface of the central shaft tube 3 at equal intervals in a circumferential array, and the arc-shaped pushing plates 16 are in close contact with the inner bottom wall of the treatment tank 1.

[0037] Furthermore, by providing the arc-shaped pushing plates 16, when the central shaft tube 3 rotates, the arc-shaped pushing plates 16 can push the solid residues deposited on the inner bottom wall of the treatment tank 1 towards the position of the slag discharge pipe 7, thereby ensuring the smooth discharge of the solid residues inside the treatment tank 1.

[0038] A heat conduction rod 17 is fixedly installed on the outer wall of the first heat conduction tube 11.

[0039] Furthermore, by providing the heat conduction rod 17, the heat conduction area between the first heat conduction tube 11 and the treatment liquid can be increased, thereby enhancing the efficiency of heat exchange and heat energy utilization.

[0040] A liquid supplement pipe 18 and a sewage discharge valve 19 are respectively embedded in the upper left and lower left of the treatment tank 1, and the liquid supplement pipe 18 is communicated with an external treatment liquid storage tank.

[0042] Furthermore, by providing the liquid supplement pipe 18 and the liquid level switch 20, when the liquid level inside the treatment tank 1 is lower than the set monitoring value of the liquid level switch 20, the external control room automatically opens the electromagnetic valve, and the treatment liquid inside the treatment tank 1 is supplemented through the liquid supplement pipe 18. After using for a certain period, the treatment liquid inside the treatment tank 1 can be discharged by opening the sewage discharge valve 19.

[0043] Finally, it should be noted that: in the attached drawings of the disclosed embodiments of the present utility model, only the structures related to the disclosed embodiments are involved, and other structures can refer to the general design.
