Abstract
Description
Technical Field
[0001] This invention relates to the field of reaction vessel technology, and in particular to a reaction vessel for producing ash water scale inhibitors and dispersants. Background Technology
[0002] A reaction vessel is a chemical container used in production processes for mixing, stirring, and reaction. It is widely used in industries such as chemical, food, pharmaceutical, and resin synthesis. For example, Chinese patent CN208356761U discloses a reaction vessel for producing ash water scale inhibitors and dispersants. It includes a reaction vessel body and a stirrer installed in the reaction vessel body. The stirring shaft of the stirrer includes an inner shaft and an outer shaft. The upper ends of the inner shaft and the outer shaft pass through the top cover of the reaction vessel body and extend to the outside of the reaction vessel body. The inner shaft and the outer shaft are threaded together. Blades are provided on the inner shaft and the outer shaft respectively. The spiral direction of the blades on the inner shaft is opposite to that of the blades on the outer shaft. A drive wheel is provided at the top of the outer shaft to drive the outer shaft to rotate. A fixing frame is provided on the top cover of the reaction vessel body. A drive component that drives the drive wheel to rotate is provided on the fixing frame. The inner shaft extends above the outer shaft. A limiting plate is provided at the top of the inner shaft. A guide rod that cooperates with the limiting plate is provided on the fixing frame.
[0003] This method uses two stirring blades rotating in opposite directions to mix liquids. It uses dynamic stirring to mix multiple liquids, which requires a lot of electricity or other energy. Furthermore, during the stirring process, the presence of the stirrer makes it difficult to control the temperature, which leads to a decrease in mixing efficiency. Summary of the Invention

[0005] The above objectives are achieved through the following technical solutions:
[0006] A reactor for producing a scale inhibitor and dispersant for ash water includes a reactor body, wherein a bent static mixing tube is disposed within the reactor body, the bent static mixing tube being distributed in a tortuous manner within the reactor body, and an inlet and an outlet are provided on the reactor body, the bent static mixing tube being connected to the inlet and the outlet.
[0007] Furthermore, the diameter of the bent static mixing tube is variable.
[0008] Furthermore, the bent static mixing tube has a first section and a second section, and the mixed liquids in the first section and the second section flow in opposite directions.
[0009] Furthermore, both the first and second sections are provided with mixing plates, which are used to mix various liquids in the bent static mixing tube.
[0010] Furthermore, a reaction tank is also provided inside the vessel body. The reaction tank is located between the bent static mixing pipe and the discharge port, and the mixed liquid in the bent static mixing pipe can enter the reaction tank to react.
[0011] Furthermore, the cross-sectional area of the reaction tank in its axial direction decreases sequentially from top to bottom.
[0012] Furthermore, it also includes a heating assembly disposed around the reaction tank, which heats the mixed liquid within the reaction tank to promote the reaction.
[0013] Furthermore, multiple bent static mixing tubes are evenly distributed along the circumference inside the reactor.
[0014] Furthermore, there are six bent static mixing tubes.

At the same time, the bent static mixing tube can effectively mix two or more liquids with high mixing efficiency.
[0017] Furthermore, the present invention includes a heating component located between the reaction tank and multiple bent static mixing tubes, which makes it difficult for the heat generated by the heating component to dissipate outside the vessel, resulting in good heat preservation.

[0028] Reference Figures 1-5 This application describes a reactor for producing a scale inhibitor and dispersant for ash water, provided in one embodiment.
[0029] A reactor for producing a scale inhibitor and dispersant for ash water includes a reactor body 100 and a bent static mixing tube 101. The reactor body 100 is provided with an inlet 110 and an outlet 104. The bent static mixing tube 101 is located between the inlet 110 and the outlet 104. One end of the bent static mixing tube 101 is a mixed liquid inlet 1011, and the other end is a mixed liquid outlet 1012. The mixed liquid inlet 1011 is connected to the inlet 110, and the mixed liquid outlet 1012 is connected to the outlet 104. The bent static mixing tube 101 is distributed in a tortuous manner inside the reactor body 100, and two or more liquids that need to be mixed are transported to the inlet 110. Multiple liquids enter the bent static mixing tube 101 from the inlet 110 for mixing.
[0030] The bent static mixing tube 101 is distributed in a tortuous manner within the vessel body 100. The mixed liquid passes through the tortuous path within the bent static mixing tube 101, thereby improving the mixing effect of the liquid and achieving the mixing requirements of the mixed liquid. The bending method of the bent static mixing tube 101 can be changed according to the type of mixed liquid to be prepared, thereby achieving the mixing requirements required for preparing different types of mixed liquids. It should be noted that when the mixed liquid passes through the bend of the bent static mixing tube 101, the velocity of the mixed liquid will change. At the same time, due to the centrifugal force and centripetal force generated by the bending path, the flow direction of the mixed liquid will change, thereby generating a vortex phenomenon in the mixed liquid. The liquid vortex phenomenon can increase the contact area of the mixed liquid to promote the mixing of multiple liquids. At the same time, the vortex phenomenon can also increase the turbulence intensity of the mixed liquid, further promoting the mixing of multiple liquids. Compared with a static mixing tube without bending curvature, the bent static mixing tube 101 of this embodiment has a higher mixing efficiency. In addition, compared with traditional stirring mixing, the static mixing method does not require a large amount of electricity or other energy, saving energy.
[0031] In a further embodiment, the diameter of the bent static mixing tube 101 is variable. When the mixed liquid enters the bent static mixing tube 101, due to the different diameters of the bent static mixing tube 101, the mixed liquid flows faster and more stably when passing through the smaller diameter section, usually exhibiting a layered flow state. When the mixed liquid flows through the larger diameter section, the mixed liquid flows slower and more unstablely, easily exhibiting a turbulent flow state. When the mixed liquid flows in the bent static mixing tube 101 with varying diameter, it is easier to generate eddies, further improving the mixing efficiency of multiple liquids.
[0032] Specifically, such as Figure 2 and Figure 3As shown, the bent static mixing tube 101 has a first section and a second section, both of which are banana-shaped, meaning they are both curved. The first and second sections face the same direction and both arch outwards. The diameters of both sections gradually increase from the sides to the middle, with the diameter of the first section being larger than that of the second section. The flow direction of the mixed liquid in the first section of the bent static mixing tube 101 is opposite to that in the second section. Specifically, the flow directions are as follows: Figure 2 As shown, when the mixed liquid flows in the first and second sections of the bent static mixing tube 101, the mixed liquid flows through parts of different diameters and changes the direction of flow, causing eddy currents to be generated in both the first and second sections of the bent static mixing tube 101, thereby promoting the mixing of multiple liquids and improving the mixing efficiency.
[0033] In a further embodiment, a mixing plate 200 is provided inside the bent static mixing tube 101, and mixing plates 200 are provided in both the first and second sections. The mixing plate 200 can further mix the liquid mixture inside the bent static mixing tube 101. The mixing plate 200 is a special component disposed inside the bent static mixing tube 101 to change the flow direction and flow velocity of the liquid mixture inside the bent static mixing tube 101, so that the liquid mixture is more likely to generate eddy currents inside the bent static mixing tube 101, thereby enhancing the mixing effect of the liquid. The mixing plate 200 can be some irregularly shaped component, such as a mesh, petal, annular plate or spiral plate. In this embodiment, the mixing plate 200 adopts such as Figure 5 The twisted blade structure shown can, of course, be of other shapes, and is not specifically limited here.
[0034] In a further embodiment, a reaction tank 103 is provided inside the vessel body 100. The reaction tank 103 is located between the mixed liquid outlet 1012 and the discharge port 104 of the bent static mixing pipe 101. After the various liquids are mixed, they enter the reaction tank 103 through the mixed liquid outlet 1012 of the bent static mixing pipe 101 and react for a period of time. The bottom of the reaction tank 103 is connected to the discharge port 104 on the vessel body 100. A valve 107 is provided at the discharge port 104. When the mixed liquid reaction is completed, the valve 107 is opened, causing the discharge port 104 to open and discharge the liquid.
[0035] Furthermore, the cross-sectional area of the reaction tank 103 decreases sequentially from top to bottom along its axial direction. It is understood that the shape of the reaction tank 103 is not a traditional cylinder; the bottom of the reaction tank 103 is a special conical or pyramidal shape, such as... Figure 2As shown, the inner surface of the reaction tank 103 is inclined at a certain angle, so that when the mixed liquid entering the reaction tank 103 flows in the vertical direction, it is affected by the inclined inner surface of the reaction tank 103, which changes the flow direction of the mixed liquid and changes the turbulence intensity of the mixed liquid, thereby increasing the degree of mixing of the mixed liquid and further improving the reaction efficiency of the mixed liquid in the reaction tank 103.
[0036] In a further embodiment, the reactor used to produce the ash water scale inhibitor further includes a heating component 105, which is disposed around the reaction tank 103. The heating component 105 can heat the reaction tank 103 to promote the reaction of the mixed liquid in the reaction tank 103. It should be noted that the temperature of the heating component 105 is adjustable and can be adjusted according to the type of liquid to be prepared.
[0037] Furthermore, multiple bent static mixing tubes 101 are evenly arranged along the circumference inside the vessel body 100. The multiple bent static mixing tubes 101 surround the heating component 105 and enclose the heating component 105, so that the heat generated by the heating component 105 is not easily lost to the outside of the vessel body 100, thus playing a heat preservation role.
[0038] A connecting member 102 is fixedly installed on the vessel body 100. The connecting member 102 connects the mixed liquid outlets 1012 of multiple bent static mixing tubes 101 together. The other end of the connecting member 102 extends into the reaction tank 103. The liquid in the multiple bent static mixing tubes 101 flows into the reaction tank 103 together through the connecting member 102 for reaction. A fixing member 106 is also installed on the vessel body 100. The fixing member 106 fixes the bent static mixing tubes 101 in the vessel body 100. The connecting member 102 also serves to fix the bent static mixing tubes 101, so that the position of the bent static mixing tubes 101 in the vessel body 100 is fixed.
[0039] Specifically, in this embodiment, such as Figure 4 As shown, there are 6 bent static mixing tubes 101 arranged in the circumferential direction inside the vessel body 100. Of course, it is not limited to 6, and it can be other numbers.
[0040] The specific working process of a reactor for producing a scale inhibitor and dispersant for ash water according to the present application is described in conjunction with the above embodiments:
[0041] Feed:
[0042] The liquid to be mixed is delivered to the inlet 110 on the vessel body 100.
[0043] mix:
[0044] The feed port 110 is connected to the mixed liquid inlet 1011 of the bent static mixing tube 101. The liquid to be mixed flows from the feed port 110 on the vessel body 100 through the mixed liquid inlet 1011 into the interior of the bent static mixing tube 101. After passing through the mixing plate 200 inside the bent static mixing tube 101, the mixed liquid travels a tortuous path inside the bent static mixing tube 101, causing a vortex phenomenon to be generated when the mixed liquid flows inside the bent static mixing tube 101, so that the liquid is uniformly mixed.
[0045] reaction:
[0046] After mixing, the mixed liquid enters the reaction tank 103 from the bent static mixing pipe 101. The mixed liquid reacts in the reaction tank 103. At the same time, the heating component 105 around the reaction tank 103 starts to work. The heating temperature of the heating component 105 is adjustable. When the temperature of the heating component 105 is adjusted to a suitable temperature, the heating component 105 starts to heat the reaction tank 103, promoting the reaction of the mixed liquid in the reaction tank 103.
[0047] Output:
[0048] After the mixed liquid in the reaction tank 103 has finished reacting, open the discharge port 104 on the vessel body 100 to discharge the mixed liquid that has finished reacting in the reaction tank 103.
[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0050] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
