Description

Technical Field

[0001] This utility model relates to the field of desulfurization nozzle filtration technology, and in particular to a filtration structure for a desulfurization nozzle. Background Technology

[0002] The filtration structure of desulfurization nozzles typically consists of multi-layer filtration components, including a top plate, a bottom plate, and multi-layer plate assemblies (such as the first and second multi-layer plates) located at the top of the delivery pipe. The slurry is delivered and filtered through a combination of connecting pipes and filter pipes. In some designs, stainless steel filter screens are used to prevent scale or foreign objects such as detached anti-corrosion layers from entering the nozzle. This structure can effectively intercept large particulate impurities and ensure uniform atomization of the slurry, thereby avoiding the problem of reduced efficiency caused by nozzle blockage or uneven slurry distribution.

[0003] Chinese Patent Publication No. CN218742575U discloses a desulfurization nozzle and a filter structure for a desulfurization device. This patent includes a pipe assembly comprising a delivery pipe and a top plate disposed on top of the delivery pipe; and a multi-layer plate assembly comprising a bottom plate disposed at the bottom of the top plate, a first multi-layer plate disposed at the bottom of the bottom plate, and a second multi-layer plate disposed at the bottom of the first multi-layer plate. It also includes a connecting pipe assembly comprising a connecting pipe disposed at one end of the delivery pipe and a filter pipe disposed at one end of the connecting pipe; and a connecting assembly comprising a sleeve disposed outside the connecting pipe and a connecting ring disposed at one end of the sleeve. This invention uses a pipe assembly to allow the slurry for desulfurization to be delivered to the nozzle body, thereby enabling desulfurization. By using the multi-layer plate assembly, the slurry sprayed from the nozzle body can be reflected, improving the atomization degree of the slurry.

[0004] In existing technologies, the filtration devices of desulfurization units mainly fill the inside of the filter tube with various filter materials to clean the sulfides inside the gas. However, the contact area between the filter material and the gas is limited, and most of the sulfides can only be removed through physical filtration, resulting in incomplete cleaning of the sulfides.

[0009] An air tube is installed at the bottom of the cannula, and an outer box is provided on one side of the cannula, with the output end of the air tube located at the bottom of the outer box.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figure 1 - Figure 4 A filter structure for a desulfurization nozzle includes an inlet pipe 1, which is the component through which sulfide gas enters the device, and further includes:

[0026] A wet and dry scrubbing assembly 3 includes a sleeve 9, the inside of which is used to install an alkaline scrubbing pad 10 and cotton 11 to achieve physical cleaning and neutralization effects. The alkaline scrubbing pad 10 is installed inside the sleeve 9, and cotton 11 is provided on one side of the alkaline scrubbing pad 10.

[0027] An air pipe 12 is installed at the bottom of the sleeve 9. The air pipe 12 is installed inside the outer box 18 and achieves the effect of liquid gas washing through the gas washing tank 13. The outer box 18 is provided on one side of the sleeve 9, and the output end of the air pipe 12 is located at the bottom of the outer box 18.

[0028] The filter structure of the desulfurization nozzle is described above. The outer box 18 is provided with a gas washing tank 13, and the gas washing tank 13 is filled with a gas washing solution to achieve a liquid cleaning effect on the gas.

[0029] The filter structure of the desulfurization nozzle is described above. The upper side of the outer box 18 is provided with holes 16. One side of each hole 16 is connected to an outlet pipe 14 and a dosing pipe 15. The outlet pipe 14 is the part for gas output, and the dosing pipe 15 is the part for liquid filtrate injection.

[0030] The filter structure of the desulfurization nozzle has an observation hole on one side of the outer box 18. An endoscope 17 is fixedly installed inside the observation hole. The endoscope 17 is used to observe the reaction status in real time so as to change the cleaning fluid in real time.

[0031] The filter structure of the desulfurization nozzle further includes:

[0032] The intake assembly 2 includes a flange 4 that is mounted on one side of the intake pipe 1. A bracket 5 is mounted on one side of the flange 4. The flange 4 is fixed to the main frame body by bolts 6. Bolts 6 are inserted and installed between the flange 4 and the bracket 5.

[0033] The filter structure of the desulfurization nozzle described above includes an array of air holes 7 at the bottom of the air inlet pipe 1, which increases the air outlet range of the air inlet pipe 1. A shoulder 8 is mounted at the bottom of the air inlet pipe 1.

[0034] The filter structure of the desulfurization nozzle is described above. The sleeve 9 has a stepped structure. The part where the sleeve 9 connects with the air inlet pipe 1 is provided with an anti-corrosion plug to increase the tightness of the connection between the air inlet pipe 1 and the sleeve 9.

[0035] Working principle:

[0036] In the actual design process, this utility model addresses the following shortcomings in the prior art: "In the prior art, the filtration device of the desulfurization unit mainly fills the inside of the filter tube with various filter materials to clean the sulfides inside the gas. However, the contact area between the filter material and the gas is limited, and most of the sulfides can only be removed by physical filtration, resulting in incomplete cleaning of the sulfides." Therefore, the air inlet assembly 2 and the dry and wet gas washing assembly 3 are specifically proposed.

[0037] Intake component 2:

[0038] The intake pipe 1 of the intake assembly 2 is the part where sulfide gas enters the device for filtration. The intake assembly 2 is fixed to the surface of the bracket 5 by flange 4 and bolts 6. The vents 7 on the intake pipe 1 increase the range of gas dispersion;

[0039] Dry and wet scrubbing unit 3:

[0040] This component achieves dry and wet gas separation during use, further enhancing the cleaning effect on sulfides. The stepped sleeve 9 is used to connect and install the dry cleaning material—cotton 11—and the alkaline gas washing pad 10; these respectively facilitate physical filtration and neutralization reaction filtration. The gas pipe 12 at the bottom of the inlet pipe 1 performs gas washing inside the gas washing tank 13, thus achieving a liquid cleaning effect. This avoids the problem of incomplete sulfide cleaning caused by a single gas washing method.

[0041] This invention utilizes a dry and wet scrubbing assembly. During use, this assembly separately incorporates physical scrubbing, chemical scrubbing, and liquid scrubbing components. The physical scrubbing component is housed within a stepped sleeve. An alkaline scrubbing pad and cotton inside the sleeve neutralize sulfides and perform physical filtration, respectively. An air pipe connected to the end of the inlet pipe extends inside the scrubbing tank, enabling both liquid and chemical scrubbing, thus enhancing the sulfide removal efficiency.
