[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0027] Example:
[0028] This embodiment describes the specific structure of a spray desulfurization device for flue gas treatment, see details below. Figures 1-4 As shown, it includes a spray tower shell 1 and a spray system 2. The spray tower shell 1 has a spray chamber 11 inside. The spray system 2 is fixedly welded to the outer wall of the spray tower shell 1. The spray system 2 is located inside and can effectively protect the internal spray device.
[0029] The outer shell 1 of the spray tower has a spray liquid replenishment port 3, which is fixedly connected to the outer wall of the spray tower shell 1. The spray liquid replenishment port 3, which is directly connected to the outside, facilitates the user's replenishment of the spray liquid. In actual use, the spray desulfurization tower is very large, and manually adding spray liquid is very time-consuming. Setting up a replenishment port on the outside allows for automatic pipeline replenishment, improving production efficiency. Moreover, three spray liquid replenishment ports 3 can also improve the fault tolerance rate, preventing the entire equipment from becoming unusable due to blockage of one port, and has a good usage effect.
[0030] like Figure 3 As shown, the spray system 2 includes a first spray pipe 21, a second spray pipe 22, and a third spray pipe 23. One end of the first spray pipe 21 is fixedly welded to the outer wall of the spray tower shell 1. One section of the second spray pipe 22 is fixedly inserted into the first spray pipe 21. The third spray pipe 23 is fixedly inserted into the second spray pipe 22. The pipes of the spray system 2 are arranged in a "tree-like" pattern, with a dispersed pipe design, ensuring that each circular plane of the desulfurization tower is sprayed with the spray liquid, further improving the spraying efficiency.
[0031] Meanwhile, in order to further improve the multi-layer spraying effect, the second spraying pipe 22 and the third spraying pipe 23 are both provided with multiple and uniform arrangements, and the spraying system 2 is provided with three groups and is arranged in a rotating staggered manner inside the spraying tower shell 1. The "tree-like distribution" that spreads in four directions makes the spraying plane more wide, and can finely spray the flue gas at each position, improving the efficiency of the first spraying.
[0032] Furthermore, in order to avoid clogging of the spraying head 24, the spraying system 2 further comprises the spraying head 24, and the multiple spraying heads 24 are fixedly connected with the third spraying pipe 23 at one end. The multiple spraying heads 24 are all arranged upward, and when the sprayed liquid inside is pressurized and quickly sprayed upward, the liquid outlet of the spraying head 24 can also be washed, avoiding clogging of the spraying head 24 by the downward dripping gypsum.
[0033] Further, as shown in Figure 4 The spraying head 24 is internally provided with the anti-clogging net 25, which is fixedly connected with the spraying head 24, avoiding clogging of the spraying head 24 by the large gypsum solids entering the inside of the spraying head 24.
[0034] The above design realizes multi-layer synchronous spraying by arranging the multi-layer spraying system 2, ensures uniform distribution of the sprayed material, further improves the effect of flue gas desulfurization, and the spraying system 2 is a multi-layer installation structure that can be freely spliced and added, can adapt to various application scenarios, and is convenient to move and disassemble.
[0035] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the utility model, and are not limited to the implementation mode. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the implementation modes. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
