Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a novel high-efficiency conversion tower for desulfurization waste liquid. Background Technology

[0002] In industrial production, various industries generate a certain amount of desulfurization wastewater that needs to be treated. In particular, the coking industry produces a large amount of desulfurization wastewater and sulfur foam. These desulfurization wastewater and sulfur foam contain various substances such as sulfur, sulfate, thiosulfate, and thiocyanate. Usually, after filtration, the solid sulfur and impurities of the desulfurization wastewater and sulfur foam are removed. Sulfates, thiosulfates, and thiocyanates are further processed in the filtrate. Thiosulfates are oxidized into sulfates, and thiocyanates are converted into sulfates for sale as industrial products. This avoids pollution and generates economic benefits.

[0003] The conversion tower can rapidly convert thiocyanate into sulfate under the action of a catalyst. Its structure mainly includes the tower body, feed structure, homogeneous mixing structure and aeration device. However, in the existing technology, the feeding process of waste liquid is limited by the structure of the feed pipeline. Therefore, after feeding, the waste liquid usually only comes into contact with the catalyst and air in a relatively fixed area of ​​a homogeneous mixing structure. Other areas far away from the inlet have a poorer contact effect with the waste liquid. This will result in a smaller actual effect of the homogeneous mixing structure, especially a lower utilization rate of the catalyst. Utility Model Content

[0004] In view of this, this utility model proposes a high-efficiency conversion tower for desulfurization wastewater with a more reasonable structural design.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a novel high-efficiency conversion tower for desulfurization wastewater, including: a tower body, a liquid distribution pipe, a homogeneous distributor, and a stirring device. The top of the tower body is provided with a liquid inlet and a gas outlet, and the bottom of the tower body is provided with a liquid outlet and a gas inlet. The liquid distribution pipe is circular and coaxially arranged on the top inner side of the tower body. The liquid distribution pipe is connected to the liquid inlet. Multiple liquid outlet holes are arranged in a circumferential array on the inner side of the liquid distribution pipe. The homogeneous distributor is fixed below the liquid distribution pipe, and the stirring device is fixedly arranged on the top of the tower body.

[0006] In the above embodiments, the liquid distribution pipe distributes the liquid inlet evenly in the circumference, avoiding the accumulation of liquid in one place, which helps to improve the mixing uniformity of the materials, thereby facilitating the uniform mixing reaction between the catalyst and the solid, liquid and gaseous materials.

[0007] In some embodiments, the liquid outlet is opened at an angle upward, and the angle between the axis of the liquid outlet and the horizontal plane is 10-80°.

[0008] In the above embodiments, the upward-facing liquid outlet can prolong the contact time between the waste liquid to be treated and the air after it comes out of the liquid outlet.

[0009] In some embodiments, an aeration pipe is also included, which is disposed at the bottom of the inner side of the tower body, is connected to the air inlet pipe, and has aeration holes on its surface.

[0010] In some embodiments, the stirring device includes a drive motor, a stirring rod, and a stirring paddle. The drive motor is fixed to the top of the tower body, the stirring rod is coaxially disposed inside the tower body, the drive motor is connected to the stirring rod in a transmission manner, and the stirring paddle is coaxially mounted on the stirring rod and located below the homogeneous distributor.

[0011] In the above embodiments, the stirring paddle is used to stir the waste liquid located below the homogeneous distributor, which can make the air after aeration mix with the waste liquid more evenly and promote the conversion reaction.

[0012] In some implementations, a feed inlet is also provided at the top of the tower.

[0013] In some implementations, a manhole is also provided at the top of the tower.

[0014] In some implementations, a drain outlet is provided at the bottom of the tower body.

[0015] The present invention has the following advantages over the prior art:

[0016] This invention improves the uniformity of waste liquid feed distribution by setting a liquid distribution pipe inside the tower. Moreover, the structure is simple. By improving the uniformity of liquid material feed distribution, it helps to promote the efficiency of the conversion reaction. Attached Figure Description

The homogeneous distributor 3 is fixed below the liquid distribution pipe 2, and the stirring device 4 is fixedly arranged on the top of the tower body 1.

[0026] In the above embodiments, the waste liquid to be treated enters the distribution pipe 2 through the inlet 11. The distribution pipe 2 distributes the waste liquid to be treated evenly along the inner wall of the tower body 1 and then discharges it through the outlet 21, thereby achieving a uniform distribution of the waste liquid to be treated. After being discharged, the waste liquid to be treated passes through the homogeneous distributor, where it comes into contact with the catalyst and the air generated by aeration for conversion reaction. Finally, the waste liquid after the reaction is discharged through the outlet 13.

[0027] In the above technical solution of liquid distribution pipe 2, in order to achieve a more uniform distribution of liquid discharged from different liquid outlets 21, multiple sets of liquid outlets 21 can be set, and the positions of the waste liquid discharged from different liquid outlets 21 are different.

[0028] In some embodiments, the liquid outlet 21 is opened at an angle upward, and the angle between the axis of the liquid outlet 21 and the horizontal plane is 10-80°.

[0029] In the above embodiments, the multiple sets of liquid outlet holes 21 can be holes with different opening angles, thereby achieving a more uniform distribution of waste liquid feed.

[0032] In the above embodiments, the aeration pipe 5 is used to evenly distribute the incoming air. The aeration pipes can be arranged in a parallel direct distribution or in a circular distribution at the bottom of the inner side of the tower body 1.

[0033] In some embodiments, the stirring device 4 includes a drive motor 41, a stirring rod 42, and a stirring paddle 43. The drive motor 41 is fixed to the top of the tower body 1, the stirring rod 42 is coaxially disposed inside the tower body 1, the drive motor 41 is connected to the stirring rod 42 in a transmission manner, and the stirring paddle 43 is coaxially mounted on the stirring rod 42 and is located below the homogeneous distributor 3.

On the one hand, it promotes the uniform mixing of gas and liquid materials. On the other hand, it can stir and break the bubbles generated by aeration to form smaller bubbles, thereby improving the contact area of ​​gas and liquid materials and increasing the reaction rate.

[0035] In some embodiments, a feed inlet 15 is also provided at the top of the tower body 1.

[0036] In the above embodiments, the feed inlet 15 can be used to replenish the catalyst material.
