Description

Technical Field

[0001] This utility model belongs to the technical field of crystallization granulation fluidized tower spraying equipment, specifically a crystallization granulation fluidized tower. Background Technology

[0002] The operating principle of chemical crystallization granulation fluidized bed softening tower is to add chemical agents to the water, causing Ca2+ in the water to react chemically to generate CaCO3 crystals, which then attach to the surface of the pre-added seed crystals, thereby reducing the hardness of the water.

[0003] In a fluidized bed crystallization tower, a certain proportion of seed crystals are first added to the water. These seed crystals can be high-purity CaCO3 crystals used in industry or natural limestone. Then, an alkaline agent, such as sodium hydroxide or calcium hydroxide, is added to the water to react with the hardness components in the water, generating CaCO3 crystals with low solubility.

[0004] Therefore, how to ensure that the seed crystals react fully with water in the crystallization granulation fluidized tower is an urgent problem to be solved in this field. Summary of the Invention

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] like Figure 1 As shown, a crystallization granulation fluidized bed includes:

[0044] Tower body 1, with a vulcanization space inside the tower body 1; a drain outlet 6 is provided at the bottom of the tower body 1; an overflow valve 3 is provided at the top of the tower body 1; the tower body 1 is mounted on a support 7.

[0045] Water inlet 4 is located at the lower part of the tower body 1;

[0046] The first water outlet 2 is located at the top of the tower body 1;

[0047] The inlet 5 is located at the lower part of the tower body 1 and is connected to the distribution pipe located inside the tower body 1. Multiple spray heads 9 are evenly arranged on the distribution pipe.

[0048] A vortex device 8 is provided, and multiple vortex devices 8 are arranged vertically inside the tower body 1.

[0049] Specifically, the water to be reacted first enters the tower body 1 through the inlet 4 and gradually moves upward. When it passes the spray head 9, it reacts chemically with the liquid sprayed from the spray head 9. Then it continues to move upward to the position of the vortex device 8, where the vortex device 8 forms a vortex water flow, further accelerating the thorough mixing of the liquid and the incompletely reacted water.

[0050] like Figure 2 As shown, the swirl device 8 includes:

[0051] 5.2 Circular Closure Device;

[0052] The jet unit 5.1 is uniformly arranged on the annular closure device 5.2.

[0053] like Figure 3 As shown, the jet unit 5.1 includes:

[0054] The main chamber 5.5 has an inlet 5.3 and a second outlet 5.4 at its upper and lower ends, respectively. The inlet 5.3 is connected to the liquid medicine connection pipe.

[0055] Feedback channel 5.6 is located on both sides of the main chamber 5.5 and is connected to the inlet 5.3 and the second outlet 5.4;

[0056] The cross-sectional area of ​​the main chamber 5.5 is greater than the cross-sectional area of ​​the feedback channel 5.6.

[0057] The feedback channels 5.6 of two adjacent jet units 5.1 form a single unit, creating a parallel common feedback channel.

[0058] Specifically, the annular closure device 5.2 has a ring-shaped structure. Water flows into the jet unit 5.1 from the inlet and forms a jet after entering the main chamber. Near the outlet of the main chamber, a small portion of the jet flows along the feedback loop near the right surface back to the inlet of the main chamber, causing the main jet to deflect to the left surface of the main chamber. This process repeats continuously, thus causing periodic pressure oscillations within the main chamber. Water is ejected from each jet unit, exhibiting a periodic oscillation that alternates between clockwise and counterclockwise on the annular cylindrical surface, forming a three-dimensional jet torus.

[0059] The vortex device 8 designed in this utility model forms a periodically oscillating jet stream when water enters the jet unit 5.1 from below and is ejected from the outlet 5.4, thereby creating a vortex.

[0060] like Figure 4-6 As shown, the spray head 9 includes:

[0061] The housing 9.1 contains a cavity 9.4 containing the liquid medicine.

[0062] Connection end 9.2 is connected to the bottom of housing 9.1, and connection channel 9.3 is provided inside connection end 9.2 for injecting liquid medicine into cavity 9.4;

[0063] The upper cover 9.7 is sealed and installed on the top of the housing 9.1;

[0064] The medicine distribution tube 9.5 connects the inside of the cavity 9.4 to the outside. The end of the medicine distribution tube 9.5 located on the outside is provided with a spray hole 9.6. A rubber ring 9.9 is fitted on the medicine distribution tube 9.5 to seal the spray hole 9.6.

[0065] Specifically, the shell 9.1 is a circular barrel structure. Multiple connection holes are provided on the upper periphery of the shell 9.1. One end of the drug distribution tube 5 is inserted into the connection hole to connect the cavity 9.4 with the outside. The connection channel 3 in the connection end 9.2 connects the drug supply end and the cavity 9.4. When the cavity 9.4 is filled with drug, the drug will enter the drug distribution tube 9.5 and then enter the chemical crystallization granulation fluidized tower from the spray hole 9.6 at the outer end of the drug distribution tube 9.5 for chemical reaction.

[0066] A rubber ring fitted onto the spray nozzle 9.6 is used to propel the liquid pesticide into the fluidized bed. Under pressure, the liquid flows towards the nozzle and pushes open the rubber ring, allowing it to be sprayed into the fluidized bed. When the pressure at the pesticide supply end decreases, the liquid is unable to push open the rubber ring sealing the nozzle 9.6, thus closing the nozzle.

[0067] The medicine distribution tube 9.5 is connected to the upper part of the housing 9.1. Multiple sets of medicine distribution tubes 9.5 are evenly distributed on the upper periphery of the housing 9.1.

[0068] Specifically, in this embodiment, four sets of drug distribution pipes 9.5 are provided, and the drug solution can enter from the four sets of drug distribution pipes 9.5 in the front, back, left, and right directions respectively, so that the drug solution can be evenly distributed throughout the entire space of the chemical crystallization granulation fluidized tower.

[0069] Multiple spray holes 9.6 are provided, which are evenly distributed around the end of the distribution tube 9.5 in an upward circumferential direction.

[0070] Specifically, in this embodiment, four spray holes 9.6 are provided, which are evenly distributed in the front, back, top, and bottom directions at the end of the drug distribution pipe 9.5. This arrangement can fill the periphery of the end of each drug distribution pipe 9.5 with liquid, so that the liquid can be evenly distributed throughout the entire space of the chemical crystallization granulation fluidized tower.

[0071] A groove is provided at the connection between the housing 9.1 and the top cover 9.7, and a sealing ring 9.8 is provided in the groove.

[0072] The groove has a triangular structure, and the sealing ring 9.8 has a triangular structure that can be embedded in the groove.

[0073] The drug distribution tube 9.5 is provided with an annular groove 9.10 at the position of the spray hole 9.6, and the rubber ring 9.9 is fitted inside the annular groove 9.10.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
