Technical Field

[0002] Coking desulfurization waste liquid usually contains a large amount of water. If it is treated directly, the workload will be huge. By concentrating it, the volume of the waste liquid can be effectively reduced. After concentrating a large amount of dilute desulfurization waste liquid into a smaller volume of concentrated liquid, the space occupied by the equipment and the processing cost will be significantly reduced during transportation, storage and further deep processing.

[0003] The concentration of coking desulfurization waste liquid requires the use of coking desulfurization waste liquid concentration equipment. However, some coking desulfurization waste liquid concentration equipment in the prior art has a slow heating reaction, which easily leads to an unsatisfactory concentration effect of the reactants, resulting in a poor concentration yield. In addition, some coking desulfurization waste liquid concentration equipment has insufficient internal stirring, which easily leads to a decrease in material extraction efficiency.

[0004] For example, the Chinese utility model patent with announcement number CN221397420U discloses a coking desulfurization waste liquid high-efficiency concentration device. The patent document clearly states in the technical issues as follows:

[0005] Some existing coking desulfurization waste liquid high-efficiency concentration equipment has poor practicality of the heating device and slow heating reaction, resulting in poor concentration effect of the reactants, thereby making the concentration yield poor. In addition, some coking desulfurization waste liquid high-efficiency concentration equipment does not have sufficient stirring, resulting in a decrease in material extraction efficiency and greatly increasing the working time.

[0006] Based on this, in order to solve the above technical problems, our R&D personnel have proposed a high-efficiency concentration equipment for coking desulfurization waste liquid. Summary of the invention

[0072] The motor 30 can drive the stirring assembly 40 through its output shaft, so that the stirring assembly 40 rotates in the inner cavity of the concentration reactor 10. When the stirring assembly 40 rotates in the inner cavity of the concentration reactor 10, the stirring assembly 40 can stir the coking desulfurization waste liquid in the concentration reactor 10; and

When the main shaft 4001 rotates, it can synchronously drive the rotation of the rotating stirring element installed on the bottom of the main shaft 4001 and the paddle stirring element installed on the lower part of the main shaft 4001. When the rotating stirring element and the paddle stirring element rotate synchronously, more fine stirring can be performed in the coking desulfurization waste liquid.

The steam in each steam distribution pipe steam outlet pipe 5003 can be sprayed into the inner cavity of the kettle body 1001 through the corresponding one-way steam nozzle 5004, and then enter into different height layers of the coking desulfurization waste liquid respectively, and form cross spraying, and then the coking desulfurization waste liquid is comprehensively heated in a cross spraying manner.

[0100] Since the flow channel in each one-way steam nozzle 5004 is one-way, the coking desulfurization waste liquid in the concentration reactor 10 will not flow back into the multi-head steam injection component 50.

[0101] More specifically, Figure 5 As shown, each one-way steam nozzle 5004 has 50041, and each 50041 can be plugged and installed in the corresponding steam distribution pipe outlet pipe 5003.

After the stirring component 40 cooperates with the steam heating mechanism, the concentration reaction of the coking desulfurization waste liquid in the concentration reactor 10 can be made more efficient, thereby improving the yield of the coking desulfurization waste liquid.

[0121] When the coking desulfurization waste liquid is concentrated, the discharge valve 20 can be unscrewed to discharge the material through the discharge pipe 10011. After the unloading is completed, the discharge valve 20 can be tightened.

[0122] More specifically, the motor 30 can drive the rotation of the main shaft 4001 through its output shaft. When the main shaft 4001 rotates, it can synchronously drive the rotation of the rotating stirring element installed on the bottom of the main shaft 4001 and the paddle stirring element installed on the lower part of the main shaft 4001. When the rotating stirring element and the paddle stirring element rotate synchronously, more precise stirring can be performed in the coking desulfurization waste liquid. In addition, the paddle stirring element and the rotating stirring element are at different height layers of the coking desulfurization waste liquid. Therefore, the paddle stirring element and the rotating stirring element can stir the coking desulfurization waste liquid at different directions at the same time, so as to improve the stirring efficiency and stirring effect of the coking desulfurization waste liquid, make the stirring of the coking desulfurization waste liquid more sufficient and thorough, and thus improve the extraction efficiency of the coking desulfurization waste liquid.

[0123] The shaft sleeve 4002 and the plurality of L-shaped stirring rods 4003 are the preferred structures of the rotating stirring element. When the main shaft 4001 rotates, the shaft sleeve 4002 can be driven to rotate, and the shaft sleeve 4002 can simultaneously drive the plurality of L-shaped stirring rods 4003, so that the plurality of L-shaped stirring rods 4003 can rotate along with the rotation of the main shaft 4001. When the plurality of L-shaped stirring rods 4003 rotate, the lower part of the coking desulfurization waste liquid can be stirred;

[0124] The stirring impeller 4004 is a preferred structure of a paddle-type stirring member. When the main shaft 4001 rotates, the stirring impeller 4004 can be driven to rotate at the same time. When the stirring impeller 4004 rotates, the middle and upper parts of the coking desulfurization waste liquid can be stirred, and while stirring, the coking desulfurization waste liquid can be made to form a vortex, which is more conducive to the stirring of the coking desulfurization waste liquid.

[0125] After the Y-shaped steam conveying structure 60 conveys the steam to the two multi-head steam filling components 50 respectively through the two free ends, the conveyed steam can enter the steam distribution pipe 5001 through the steam distribution pipe steam inlet pipe 5002, and then enter the multiple steam distribution pipe steam outlet pipes 5003 through the steam distribution pipe 5001 respectively. The steam in each steam distribution pipe steam outlet pipe 5003 can be sprayed into the inner cavity of the kettle body 1001 through the corresponding one-way steam nozzle 5004, and then enter into different height layers of the coking desulfurization waste liquid respectively, and form cross spraying, and then the coking desulfurization waste liquid is comprehensively heated in a cross spraying manner.

[0126] Since the flow channel in each one-way steam nozzle 5004 is one-way, the coking desulfurization waste liquid in the concentrated reactor 10 will not flow back into the multi-head steam injection component 50;

[0127] After the steam delivery pipe delivers the steam to the three-way steam distributor 6001 through the steam inlet end 60011, two steam paths are formed inside the three-way steam distributor 6001. The two steam paths can flow to the corresponding steam delivery pipe 6002 through the steam outlet end 60012, and then the steam is delivered to the corresponding steam distribution pipe 5001 through the steam delivery pipe 6002.

[0128] The two sets of embedded structures can facilitate the installation of two sets of multi-head steam filling components 50 on the kettle body 1001;

[0129] Each assembly hole 10013 can facilitate the installation of the corresponding one-way steam nozzle 5004 . After the one-way steam nozzle 5004 is installed in the corresponding assembly hole 10013 , the nozzle of each one-way steam nozzle 5004 is located in the inner cavity of the kettle body 1001 .

[0130] The above different embodiments can be combined, replaced and used in conjunction with each other.
