DETAILED DESCRIPTION

[0032] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below, obviously, the described embodiments are a part of the embodiments of the utility model, rather than all the embodiments; on the basis of the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the range of protection of the utility model.

[0033] As shown in Figure 1 A crystallization prilling catalytic softening fluidized tower, comprising:

[0034] Tower body 1, reaction space is arranged inside the tower body 1, overflow valve 3 is arranged on the upper part of the tower body 1, drainage outlet 6 is arranged at the bottom of the tower body 1, and the tower body 1 is installed on bracket 7;

[0035] Water outlet 2, the water outlet 2 is arranged at the top of tower body 1;

[0036] Water inlet 4, the water inlet 4 is arranged at the lower part of the tower body 1;

[0037] Cyclone mixing device 5, the cyclone mixing device is arranged in the tower body 1, and is located at the position above the water inlet 4;

[0038] Medicine inlet 9, the medicine inlet 9 is connected with the cyclone mixing device 5 through a pipeline.

[0039] Specifically, water enters the reaction space arranged inside the tower body 1 from the water inlet 4, gradually rises, and chemically reacts with the medicine liquid containing seed crystals sprayed by the cyclone mixing device 5 when passing through the cyclone mixing device 5.

[0040] As shown in Figure 2 The cyclone mixing device 5 comprises:

[0041] Intermediate cavity 5.2;

[0042] Outer annular cavity 5.3, the outer annular cavity 5.3 is arranged outside the intermediate cavity 5.2, and the intermediate cavity 5.2 and the outer annular cavity 5.3 are in communication with the medicine inlet 9;

[0043] Cyclone sheet 5.1, 36 cyclone sheets 5.1 are arranged, and the 36 cyclone sheets 5.1 are annularly connected between the intermediate cavity 5.2 and the outer annular cavity 5.3.

[0044] The spray head 8 is provided with a plurality of spray heads 8, which are respectively installed on the middle cavity 5.2 and the outer annular cavity 5.3.

[0045] Specifically, the spiral flow mixing device 5 is fixed in the tower body 1 by the frame body. When the water rises, the spiral flow is formed when the water passes through the spiral flow piece 5.1. The spiral flow then fully reacts with the seed crystal liquid sprayed by the spray head 8, which can ensure the full chemical reaction. The spray head 8 is uniformly distributed on the upper side of the middle cavity 5.2 and the outer annular cavity 5.3, and the spray head 8 uniformly sprays the liquid containing the seed crystal.

[0046] The spiral flow piece 5.1 is arranged at an angle of 30° with the horizontal direction.

[0047] As shown in Figure 3 The spray head 8 is provided with a cavity 8.2 for accommodating the liquid. The spray head 8 is made of flexible material, and a plurality of spray holes 8.3 are arranged on the spray head 8.

[0048] The connecting end 8.4 is connected to the spray head 8, and the connecting channel 8.5 in the connecting end 8.4 is in communication with the cavity 8.2.

[0049] The spray head 8 is made of rubber or silicone.

[0050] The spray hole 8.3 is formed by piercing the spray head 8 with a needle. The spray hole 8.3 is arranged in multiple rows from top to bottom along the spray head 8, and each row is uniformly provided with a plurality of spray holes 8.3. The size of the spray hole 8.3 satisfies that when the cavity 8.2 in the spray head 8 is not full of liquid, the spray hole 8.3 is closed; when the cavity 8.2 in the spray head 8 is full of liquid, the spray hole 8.3 is opened.

[0051] The spray head 8 and the connecting end 8.4 are an integral structure.

[0052] The spray hole 8.3 is formed by piercing the spray head 8 with a needle. The spray hole 8.3 is arranged in multiple rows from top to bottom along the spray head 8, and each row is uniformly provided with a plurality of spray holes 8.3.

[0053] Specifically, when the spray hole 8.3 is made, a needle of appropriate size is directly pierced into the spray head 8 to form the spray hole 8.3. At this time, since the spray head 8 is made of flexible material, the spray hole 8.3 is normally closed under the physical properties of the flexible material itself after being formed. However, if the liquid in the cavity 8.2 is full, there will be an outward pressure on the cavity 8.2, which will open the spray hole 8.3 under the action of the pressure, so that the liquid in the cavity 8.2 is also uniformly sprayed into the chemical crystallization granulation fluidized tower.

[0054] When the pressure is less than a certain value, the medicine injection hole 8.3 is automatically closed. In comparison with directly closing the medicine injection hole 8.3 by using a switch, although there is a process for the pressure provided by the medicine liquid supply end to decrease, the medicine injection hole 8.3 is directly closed when the pressure is less than a certain value, and there is no gradual process. Therefore, the supply amount of the medicine liquid can be ensured.

[0055] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
