Description

Technical Field

[0001] The present application relates to the technical field of wet desulfurization, and in particular to a spray range detection device for an absorption tower. Background Art

[0002] At present, most of the wet desulfurization technologies use spray towers. The circulating pump outside the tower transports the slurry at the bottom of the absorption tower to the upper part of the absorption tower, and then sprays it out through the nozzle to form a droplet spray layer, which conducts mass and heat transfer with the flue gas. However, although the anti-corrosion layer in the tower and the anti-corrosion layer of the spray device support frame have good anti-corrosion performance against the slurry, due to the presence of undissolved solid particles in the slurry, when these high-speed moving solid particles are sprayed onto the inner wall of the desulfurization absorption tower and the spray device support frame, they will produce violent scouring, causing the anti-corrosion layer to be abraded and fall off, thereby causing corrosion and perforation of the inner wall of the desulfurization absorption tower and the spray device support frame, reducing the local structural strength of the desulfurization absorption tower and the spray device support frame, and in severe cases threatening the safe operation of the desulfurization absorption tower.

[0003] Therefore, the present application aims to provide a spray range detection device for an absorption tower, which is used to detect the spray range of the slurry sprayed by the spray device, so as to adjust the installation position of the spray device to avoid the slurry directly scouring the inner wall of the desulfurization absorption tower and the support frame of the spray device, thereby extending the service life of the anti-corrosion layer of the inner wall of the desulfurization absorption tower and the anti-corrosion layer of the support frame of the spray device.

[0031] Before introducing the technical solution of the present application, it is necessary to explain the creation background of the invention of the present application. The present application aims to provide a spray range detection device for an absorption tower, which is used to detect the spray range of the slurry sprayed by the spray device, so as to adjust the installation position of the nozzle of the spray device, so as to avoid the slurry from directly scouring the inner wall of the desulfurization absorption tower and the support frame of the spray device, and to extend the service life of the anti-corrosion layer of the inner wall of the desulfurization absorption tower and the anti-corrosion layer of the support frame of the spray device.

[0032] For example embodiments of this application, please refer to Figure 1 and Figure 2 , a spray range detection device for an absorption tower is provided, the detection device comprises a positioning rod 1 installed on the outer edge of a nozzle 5 through a clamping member 11, and a measuring ruler 2 hinged to one end of the positioning rod 1 through a connecting pin 3, wherein the positioning rod 1 can adjust the installation position on the outer edge of the nozzle 5. In actual use, first, the positioning rod 1 is installed on the outer edge of the nozzle 5 through the clamping member 11, and the measuring ruler 2 is hinged through the connecting pin 3, the measuring ruler 11 can be rotated around the hinge point to a desired angle, and at the same time, the installation position of the positioning rod 1 on the outer edge of the nozzle 5 can be adjusted through the clamping member 11, so that the measuring ruler 2 can detect the spray range of the slurry sprayed from the nozzle at different positions. By using the above detection device, the present application has the following advantages: 1. The present application can be quickly installed at the nozzle 5, and the spraying range of the slurry sprayed from the nozzle 5 can be visually inspected and measured by the measuring ruler 2. The relatively accurate measurement data can be used to determine whether the slurry will cause erosion to the anti-corrosion layer of the inner wall of the desulfurization absorption tower and the anti-corrosion layer of the spray device support frame, and then the nozzle installation angle can be adjusted as needed. 2. The present application has a simple structure and is easy to use, and can be used for nozzles with different spray angles, unidirectional and multi-directional.

[0033] In some embodiments, the hinge point of the measuring ruler 2 is close to the outer edge of the nozzle 5. Figure 2 The hinge point of the measuring ruler 2 should be close to the outer edge of the nozzle 5 so that the outermost spray path of the slurry sprayed from the nozzle 5 can be detected more accurately to minimize the observation error.

[0034] In some embodiments, the portion from the hinge point to the end of the measuring ruler 2 is an abutment portion 21, and the abutment portion 21 can abut against the chamfered surface 51 of the inner wall of the nozzle 5. Figure 2The inner wall of the nozzle 5 is chamfered, and the chamfered slope 51 can constrain the slurry spraying direction. The abutment portion 21 can abut against the chamfered slope 51, so that the measuring ruler 2 is consistent with the constrained direction, so that the measuring ruler 2 can more accurately reflect the outermost spraying path of the slurry. Further, the length of the abutment portion 21 is not greater than the length of the chamfered slope 51, and the length of the abutment portion 21 is 10 to 30 mm. In this way, the abutment between the abutment portion 21 and the chamfered slope 51 can constrain the measuring ruler 11 to enhance the objectivity of the detection.

[0035] In some embodiments, two mutually parallel positioning rods 1 are disposed on the outer edge of the nozzle 5, and the two positioning rods 1 are connected by the connecting pin 3, and the measuring ruler 2 is disposed between the two positioning rods 1. Figure 1 On the basis that the measuring ruler 2 is hinged to one end of the positioning rod 1 through the connecting pin 3, a pair of positioning rods 1 are arranged on the outer edge of the nozzle 5 and are parallel to each other and connected through the connecting pin 3. Furthermore, the measuring ruler 2 is sandwiched between the two positioning rods 1. The structure in which the measuring ruler 2 is arranged between the two positioning rods 1 improves the stability of the installation and matching between the measuring ruler 2 and the positioning rods 1. Furthermore, at least one end of the two positioning rods 1 is fixedly connected by a connecting rod 4. Based on the basis that the two positioning rods 1 are connected by the connecting pin 3, in order to make it have a stable connection strength, at least one end of the double positioning rod 1 is provided with a connecting rod 4 to improve the overall connection strength of the double positioning rod 1.

[0036] In some embodiments, a damper is provided between the measuring ruler 2 and the connecting pin 3. Specifically, a damper is provided at the contact point where the measuring ruler 2 and the connecting pin 3 are hinged, so that the rotation of the measuring ruler 2 around the hinge point is resisted, so as to prevent the measuring ruler 2 from being too loose during use of the detection device and affecting the detection process.

[0037] In some embodiments, the measuring ruler 2 is 1000-1200 mm long, and the measuring ruler 2 is a retractable ruler structure. For ease of carrying and storage, the measuring ruler 2 of the detection device is a retractable ruler structure. Specifically, the measuring ruler 2 is composed of several sections of scales, and the length of each section of the scale is 12-20 mm. It should be noted that the measuring ruler 2 can be made of several sections of scales with a folding structure, or it can be made of several sections of scales with a sleeve structure. This application does not make specific restrictions on this, and it only needs to satisfy that the measuring ruler 2 is a retractable ruler for easy carrying and storage.

[0038] Preferably, the positioning rod and the measuring ruler are made of corrosion-resistant materials, such as nickel-based alloy, chloroprene rubber, etc., which can effectively prevent the desulfurization slurry sprayed from the nozzle from eroding and corroding the positioning rod and the measuring ruler, thereby extending the service life of the detection device and reducing the user's maintenance cost.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
