Description

Technical Field

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

[0002] The operating principle of chemical crystallization granulation fluidized bed water softening 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 process, 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 cause the hardness components in the water to react and generate CaCO3 crystals with low solubility.

[0004] The advantages of chemical crystallization granulation fluidized bed water softening technology include good treatment effect, stable operation, and low energy consumption. Furthermore, because this technology uses chemical agents, the degree of hardness removal in the water can be flexibly adjusted to adapt to different water quality conditions and effluent requirements.

[0005] Since chemical reagents need to be uniformly sprayed inside the fluidized bed for reaction in chemical crystallization granulation, a spray head needs to be designed to ensure that the chemical reagents can be sprayed accurately and uniformly. Summary of the Invention

[0006] This invention provides a spray head for a crystallizing, granulating, catalytic softening fluidized bed to solve the problem of uneven spraying of chemical solutions in fluidized bed towers.

[0025] like Figure 1 , 2 As shown, a spray head for a crystallization granulation catalytic softening fluidized bed includes:

[0026] Housing 1, wherein a cavity 4 containing liquid medicine is provided inside the housing 1;

[0027] Connection end 2, which is connected to the bottom of the housing 1, and a connection channel 3 is provided inside the connection end 2 for injecting the medicine into the cavity 4;

[0028] Top cover 7, which is sealed and installed on the top of housing 1;

[0029] The medicine distribution tube 5 connects the inside of the cavity 4 to the outside. The medicine distribution tube 5 has a spray hole 6 at the outside end. A rubber ring 9 is fitted on the medicine distribution tube 5 to seal the spray hole 6.

[0030] Specifically, the shell 1 is a circular barrel structure. Multiple connection holes are provided on the upper periphery of the shell 1. One end of the drug distribution tube 5 is inserted into the connection hole to connect the cavity 4 with the outside. The connection channel 3 in the connection end 2 connects the drug supply end and the cavity 4. When the cavity 4 is filled with drug, the drug will enter the drug distribution tube 5 and then enter the chemical crystallization granulation fluidized tower from the spray hole 6 at the outer end of the drug distribution tube 5 for chemical reaction.

[0031] A rubber ring fitted onto the spray nozzle 6 is used to propel the liquid pesticide, which, under pressure, flows into the nozzle and pushes open the rubber ring before being sprayed into the fluidized bed. When the pressure at the pesticide supply end decreases, the liquid pesticide can no longer push open the rubber ring sealing the nozzle 6, thus closing the nozzle 6.

[0032] This invention automatically controls the opening and closing of the spray nozzle 6 by adjusting the pressure of the cavity 4 at the liquid supply end.

[0033] The medicine distribution tube 5 is connected to the upper part of the housing 1. Multiple sets of medicine distribution tubes 5 are provided and are evenly distributed on the upper periphery of the housing 1.

[0034] Specifically, in this embodiment, four sets of drug distribution pipes 5 are provided, and the drug liquid can enter from the four sets of drug distribution pipes 5 in four directions: front, back, left, and right, so that the drug liquid can be evenly distributed throughout the entire space of the chemical crystallization granulation fluidized tower.

[0035] Multiple spray holes 6 are provided, which are evenly distributed at the end of the drug distribution tube 5 in a circumferential upward direction.

[0036] Specifically, in this embodiment, four spray holes 6 are provided, which are evenly distributed in the front, back, up, down and front directions at the end of the drug distribution pipe 5. This arrangement can fill the periphery of the end of each drug distribution pipe 5 with liquid medicine, so that the liquid medicine can be evenly distributed throughout the entire space of the chemical crystallization granulation fluidized tower.

[0037] A groove is provided at the connection between the housing 1 and the upper cover 7, and a sealing ring 8 is provided in the groove. The groove has a triangular structure, and the sealing ring 8 has a triangular structure that can be embedded in the groove.

[0038] Specifically, the sealing ring 8 is used to seal the connection between the housing 1 and the upper cover 7. In this embodiment, both the groove and the sealing ring 8 are designed as triangular structures, with one side aligned with the outer wall of the housing 1. This ensures that the external pressure on the sealing ring 8 is high, and the water pressure inside the chemical crystallization granulation fluidized tower further enhances the sealing effect.

[0039] The medicine distribution tube 5 is provided with a groove 10 at the position of the spray hole 6, and the rubber ring 9 is fitted inside the groove 10.

[0040] 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.
