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.

[0007] This utility model adopts the following technical solution: a spray head for a crystallization granulation catalytic softening fluidized bed, comprising:

[0008] A spray head housing, wherein a cavity is provided inside the spray head housing to contain liquid pesticide;

[0009] The lower connection end is connected to the bottom of the spray head housing, and a connection channel is provided inside the lower connection end for connecting the cavity and the liquid supply end.

[0010] The upper connecting end is connected to the top of the spray head housing, and a connecting cavity is provided inside the upper connecting end, with the connecting cavity communicating with the cavity;

[0011] The upper cover is installed on the upper connecting end. A cover made of flexible material is set in the middle of the upper cover, and multiple medicine spray holes are provided on the cover.

[0012] In some embodiments, the liquid spray nozzle is formed by puncturing the cap with a needle.

[0013] In some embodiments, the cover is made of rubber or silicone.

[0014] In some embodiments, the spray head housing, lower connecting end, and upper connecting end are an integral structure.

[0015] In some embodiments, the spray head housing, the lower connecting end, and the upper connecting end are all hollow cylindrical structures, wherein the inner diameter of the spray head housing is larger than the inner diameters of the lower connecting end and the upper connecting end, and the inner diameters of the lower connecting end and the upper connecting end are the same.

[0016] In some embodiments, the cover is a circular structure, and the diameter of the cover is equal to the inner diameter of the upper connecting end.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The cover of this invention is made of rubber or silicone. Because the cover is made of a flexible material, the spray nozzle is normally closed after it forms due to the inherent physical properties of the flexible material. However, when the cavity is filled with liquid, it exerts an outward pressure on the cover, which opens the spray nozzle, thus evenly spraying the liquid into the chemical crystallization granulation fluidized tower. This application also features evenly distributed spray holes at the top of the spray head, ensuring timely and uniform liquid spraying. Attached Figure Description

[0022] 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.

[0023] The structures, proportions, and sizes illustrated in the accompanying drawings are solely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0024] like Figure 1 , 2 As shown, a spray head for a crystallization granulation catalytic softening fluidized bed includes:

[0025] The spray head housing 1 has a cavity 5 inside for containing liquid medicine;

[0026] Lower connecting end 2 is connected to the bottom of the spray head housing 1. A connecting channel 6 is provided inside the lower connecting end 2 for connecting the cavity 5 and the liquid supply end.

[0027] Upper connecting end 3 is connected to the top of the spray head housing 1, and a connecting cavity 7 is provided inside the upper connecting end 3, which is in communication with the cavity 5;

[0028] The upper cover 4 is installed on the upper connecting end 3. The upper cover 4 has a cover 8 made of flexible material in the middle, and the cover 8 has multiple medicine spray holes 9.

[0029] The upper cover 4 is sealed to the upper connecting end 3. A round hole is provided in the middle of the upper cover 4, and the cover 8 is installed in the round hole and connected to the upper cover 4 as one piece.

[0030] The medicine spray nozzle 9 is formed by piercing the cap 8 with a needle. The cap 8 is made of rubber or silicone.

[0031] Specifically, the size of the liquid spray nozzle 9 is such that when the cavity 5 inside the spray head housing 1 is not full of liquid, the liquid spray nozzle 9 is closed; when the cavity 5 inside the spray head housing 1 is full of liquid, the liquid spray nozzle 9 is open. The liquid supply end pumps the liquid into the cavity 5 in the spray head housing 1 via a pump. After the cavity 5 is full of liquid, it will exert pressure on the cover 8. Since the cover 8 is made of flexible material, the liquid spray nozzle 9 is closed when there is no outward tension on the cover 8. When the pressure exerted on the cover 8 after the liquid is full reaches a certain threshold, the liquid spray nozzle 9 will open, thereby spraying the liquid into the chemical crystallization granulation fluidized tower for chemical reaction.

[0032] The spray head housing 1, lower connecting end 2, and upper connecting end 3 are an integral structure. All three are hollow cylindrical structures, with the inner diameter of the spray head housing 1 being larger than the inner diameters of the lower connecting end 2 and the upper connecting end 3, while the inner diameters of the lower connecting end 2 and the upper connecting end 3 are the same. The cover 8 is circular, and its diameter is equal to the inner diameter of the upper connecting end 3.

[0033] Specifically, the lower connecting end 2 and the upper connecting end 3 have the same inner diameter, which can ensure that the pressure provided by the liquid supply end to the lower connecting end 2 is the same as the pressure provided by the upper connecting end 3 to the cover 8. The uniformly arranged liquid spray holes 9 are all opened under the action of pressure, and the liquid is evenly sprayed into the chemical crystallization granulation fluidized tower from the liquid spray holes 9.

[0034] 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.
