Description

Technical Field

[0001] This utility model relates to the technical field of environmental protection equipment, and in particular to an absorbent spray nozzle for desulfurization and denitrification. Background Technology

[0002] Desulfurization and denitrification are important environmental protection technologies. In the field of industrial waste gas treatment, desulfurization and denitrification are key links in reducing air pollutant emissions and protecting the environment. At present, the method of spraying absorbents into waste gas to remove sulfur dioxide and nitrogen oxides is widely used, and the absorbent spray nozzle is the core component in this treatment process.

[0003] To ensure the normal operation of the nozzles, they must be cleaned and replaced frequently, which not only increases the workload of equipment maintenance but also leads to a significant increase in labor costs.

[0004] In actual use, impurities in industrial waste gas, particulate matter in absorbent, and precipitates that may be generated during the reaction process can easily accumulate inside existing spray nozzles. If the nozzle orifice is blocked, the spray volume and spray state of the absorbent will change, deteriorating the spray uniformity and exacerbating the decline in desulfurization and denitrification effects. Therefore, it is necessary to provide an absorbent spray nozzle for desulfurization and denitrification that allows for regular cleaning of the filter screen and further improves anti-clogging performance.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Given that in the current technology, impurities in industrial waste gas, particulate matter in absorbent, and precipitates that may be generated during the reaction process tend to accumulate inside the nozzle during actual use, and that the spray volume and spray state of the absorbent will change when the nozzle orifice is blocked, thus worsening the spray uniformity and exacerbating the decline in desulfurization and denitrification effects, this technology solves the problems in the existing technology.

[0031] like Figure 1-4 As shown, this embodiment of the utility model provides an absorbent spray nozzle 13 for desulfurization and denitrification, comprising: a spraying component 1, which includes: a pipe port 11 and a support base 12, the pipe port 11 being connected to the middle of the bottom end of the support base 12; a spray nozzle 13, connected to the top of the support base 12; and a nozzle 14, connected to the middle of the top end of the spray nozzle 13. An external pipe body is connected to the pipe port 11, and liquid is transferred through the pipe body and the pipe port 11, so that the liquid is sprayed to the outside through the spray nozzle and the nozzle 14. A filter component 2 includes: a support ring 21, connected to the inner surface of the pipe port 11; a rotating rod 22, installed in the middle of the support ring 21; a limiting ring 23, connected to the outer surface of the rotating rod 22; and a filter screen 24, detachably connected between the support ring 21 and the limiting ring 23.

[0032] After the liquid enters the interior of the inlet 11, it is filtered by the filter screen 24. The collar 27 is fitted onto the upper and lower parts of the outer surface of the rotating rod 22; the horizontal plate 25 is connected to both sides of the outer surface of the collar 27; the brush head 26 is connected to the outer surface of the horizontal plate 25 and is respectively attached to the top and bottom of the filter screen 24.

[0033] The brush head 26 is positioned at the top and bottom of the filter screen 24. The motor 28 operates, driving the rotating rod 22 to rotate, and the horizontal plate 25 rotates accordingly, so that the brush head 26 can clean the top and bottom of the filter screen 24.

[0034] Furthermore, the filter component 2 also includes a motor 28, connected to the middle of the bottom end of the rotating rod 22. Furthermore, it also includes a fixing component 3, which includes a positioning hole 31, formed inside the limiting ring 23; and a positioning rod 33, connected to the outer surface of the collar 27 and inserted into the positioning hole 31.

[0035] The collar 27 is sleeved on the top and bottom of the rotating rod 22, so that the positioning rod 33 is inserted into the positioning hole 31 to fix the collar 27. Furthermore, the fixing component 3 also includes a clamping ring 32, which is connected to the outer surface of the collar 27 and clamps the outer surface of the limiting ring 23.

[0036] After the collar 27 is installed on the top and bottom of the limiting ring 23, the clamping ring 32 simultaneously clamps the outside of the limiting ring 23, further reinforcing it. Furthermore, the fixing component 3 also includes: a base plate 34, connected to the outer surface of the motor 28; and a groove 35, formed inside the base plate 34.

[0037] The rotating rod 22 is supported by the bottom plate 34.

[0038] The working principle is as follows: First, the collar 27 and the limiting ring 23 are sleeved on the outside of the rotating rod 22. The positioning rod 33 is inserted into the inside of the positioning hole 31, so that the collar 27 is located at the top and bottom of the limiting ring 23. At the same time, the clamping ring 32 is clamped on the outside of the limiting ring 23, which further reinforces the collar 27 and the limiting ring 23. The filter screen 24 is installed between the support ring 21 and the limiting ring 23 to filter impurities in the absorbent. The outer surface of the horizontal plate 25 is equipped with a washing head 26, which is located at the top and bottom of the filter screen 24. The motor 28 runs, driving the rotating rod 22 to rotate, and the horizontal plate 25 rotates accordingly. In this way, the washing head 26 can clean the top and bottom of the filter screen 24, preventing impurities from clogging the filter screen 24 and further improving the anti-clogging performance.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, it also includes a reinforcing component 4, which includes: an inner groove 45, which is formed on the inner surface of the pipe opening 11; a support rod 46, which is connected to the middle of the inner surface of the inner groove 45; a second snap-fit ​​block 47, which is connected to the outer wall of the support ring 21 and the base plate 34 respectively; and an insertion hole 48, which is formed in the middle of the second snap-fit ​​block 47 and is inserted into the outside of the support rod 46.

[0040] Furthermore, the reinforcing component 4 also includes: an inner groove 44, which is formed on the outer surface of the pipe opening 11; and a positioning ring 41, which is embedded in the interior of the inner groove 44.

[0041] After the support ring 21 is installed inside the pipe opening 11, the positioning ring 41 is embedded inside the inner groove 44 to prevent the support ring 21 from becoming loose. Furthermore, the reinforcing component 4 also includes: a snap-fit ​​block 42 connected between multiple positioning rings 41; and a hole 43 formed in the middle of the snap-fit ​​block 42 and inserted into the outside of the support rod 46.

[0042] The first snap-fit ​​block 42 is inserted into the inner groove 45, corresponding to the second snap-fit ​​block 47, and is positioned accordingly.

[0043] Working principle: First, after the support ring 21 is installed inside the pipe opening 11, the insertion hole 48 is aligned with the support rod 46 and inserted, so that the second snap-fit ​​is embedded inside the inner groove 45, and the support ring 21 and the base plate 34 are installed and fixed inside the pipe opening 11. Then, the positioning ring 41 is embedded inside the inner groove 44, while the hole 43 is inserted into the outside of the upright, so that the first snap-fit ​​block 42 is embedded inside the inner groove 45, corresponding to the second snap-fit ​​block 47.
