Description

Technical Field

[0001] This utility model belongs to the field of high-temperature gas cooling technology, specifically relating to a high-temperature gas cooling mechanism for carbon emission reduction in thermal power plants. Background Technology

[0002] Thermal power plants are an important part of electricity production. When cooling high-temperature gases, the pipelines that transport the high-temperature gases need to be extended to the bottom of the pipeline filled with cooling water. Then, the gas is sprayed into the cooling water so that it can be cooled. However, the cooling water is always in a relatively calm state, which results in the cooling water temperature being higher in the part of the pipeline that is extended, while the cooling water temperature is lower in the part that is further away from the pipeline, thus affecting the gas cooling effect. Utility Model Content

[0003] The purpose of this invention is to provide a high-temperature gas cooling mechanism for carbon emission reduction in thermal power plants, aiming to solve the problem of uneven water temperature in pipelines leading to unsatisfactory gas cooling effect in the aforementioned background technology.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A high-temperature gas cooling mechanism for carbon emission reduction in thermal power plants includes a cooling box and an auxiliary cooling box. A first pump body is provided on one side of the auxiliary cooling box, and the first pump body is connected to a first connecting pipe. The first connecting pipe is connected to a fixed box, which is located on one outer wall of the cooling box. A cooling structure is provided on the other outer wall of the cooling box. A stirring structure is provided inside the cooling box. A filter structure is provided on the outer wall of the auxiliary cooling box away from the first pump body. A spray plate is provided at the top of the inner wall of the auxiliary cooling box.

[0006] Furthermore, the stirring structure includes a second connecting pipe that penetrates the outer wall of the cooling tank and connects to the fixed box. The stirring structure also includes a baffle plate and a second rotating shaft. The baffle plates are staggered and arranged on the inner wall of the cooling tank. The second rotating shaft penetrates and connects to the inner wall of the cooling tank and is connected to a stirring blade.

[0007] Furthermore, the cooling structure includes a second pump body connected to the other side of the cooling box, the output end of the second pump body being connected to a third connecting pipe, the third connecting pipe being connected to a cooling machine, the top of the cooling machine being connected to a fourth connecting pipe, and the fourth connecting pipe being connected to the outer wall of the cooling box.

[0008] Furthermore, the filtration structure includes a fifth connecting pipe that is connected to the outer wall of the auxiliary cooling box. A filter box is connected to one side of the fifth connecting pipe. An installation groove is provided at the top of the filter box, and a filter plate is fitted into the inner wall of the installation groove.

[0009] Furthermore, the inner wall bearing of the fixed box is rotatably connected to a first rotating shaft, the first rotating shaft is provided with a rotating blade, the end of the first rotating shaft is rotatably connected to a conveyor belt, and the other end of the conveyor belt is rotatably disposed at the end of the second rotating shaft.

[0010] Furthermore, the damping plate has wave grooves on both its upper and lower surfaces.

[0011] The beneficial effects of this utility model are:

[0012] (1) In this utility model, the gas passes through the filter structure on the outer wall of the auxiliary cooling box to filter impurities and dust in the gas to prevent blockage. Then, the gas is initially cooled by the spray plate inside the auxiliary cooling box to improve the subsequent cooling effect of the gas.

[0013] (2) In this utility model, the gas is blown into the fixed box by the first pump body, which further drives the stirring structure in the cooling box to start stirring, so that the cooling water in the cooling box is always in an internal flow state. At the same time, the cooling structure set on the outer wall of the cooling box makes the cooling water circulate into the cooling box. During this process, the cooling water is always in an internal flow state, and the water temperature is kept uniform. Furthermore, several baffles in the stirring structure slow down the distance the gas moves on the outer wall, and prolong the cooling time of the gas in the cooling water.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-5 As shown, a high-temperature gas cooling mechanism for carbon emission reduction in a thermal power plant includes a cooling box 1 and an auxiliary cooling box 2. A first pump body 311 is provided on one side of the auxiliary cooling box 2, and the first pump body 311 is connected to a first connecting pipe 312. The first connecting pipe 312 is connected to a fixed box 313, which is located on one side of the outer wall of the cooling box 1. A cooling structure is provided on the other side of the outer wall of the cooling box 1. A stirring structure is provided inside the cooling box 1. A filter structure is provided on the outer wall of the auxiliary cooling box 2 away from the first pump body 311. A spray plate 324 is provided at the top of the inner wall of the auxiliary cooling box 2, which can perform preliminary cooling of the gas.

[0022] Specifically, the stirring structure includes a second connecting pipe 316 that penetrates the outer wall of the cooling tank 1 and connects to the fixed box 313. The stirring structure also includes a baffle plate 317 and a second rotating shaft 318. Several baffle plates 317 are staggered on the inner wall of the cooling tank 1 to further improve the cooling effect of the gas in the cooling water. The second rotating shaft 318 penetrates the inner wall of the cooling tank 1 and is connected to stirring blades 319. There are several stirring blades 319, which are evenly and equidistantly distributed on the outer wall of the second rotating shaft 318. This allows for comprehensive stirring of the cooling water inside the cooling tank 1, thereby improving the fluidity of the cooling water and creating interaction between the left and right sides, thus improving the cooling effect.

[0023] Specifically, the cooling structure includes a second pump body 3111 connected to the other side of the cooling box 1, a third connecting pipe 3112 connected to the output end of the second pump body 3111, a cooler 3113 connected to the third connecting pipe 3112, a fourth connecting pipe 3114 connected to the top of the cooler 3113, and the fourth connecting pipe 3114 connected to the outer wall of the cooling box 1.

[0024] Specifically, the filtration structure includes a fifth connecting pipe 321 connected to the outer wall of the auxiliary cooling box 2. A filter box 322 is connected to one side of the fifth connecting pipe 321. The top of the filter box 322 has an installation groove, and a filter plate 323 is fitted into the inner wall of the installation groove. The filter plate can filter large particulate impurities and dust in the gas to prevent blockage. In addition, when replacing the filter plate 323, simply pull the filter plate 323 upward to remove it from the filter box 322.

[0025] Specifically, a first rotating shaft 314 is rotatably connected to the bearing on the inner wall of the fixed box 313. A rotating blade 315 is provided on the rotating rod of the first rotating shaft 314. A conveyor belt 3110 is rotatably connected to the end of the first rotating shaft 314. The other end of the conveyor belt 3110 is rotatably located at the end of the second rotating shaft 318.

[0026] Specifically, the upper and lower surfaces of the buffer plate 317 are provided with wave grooves, which can slow down the distance that the gas moves on its outer wall, thereby extending the cooling time of the gas in the cooling water.

[0027] In practical applications, the high-temperature gas is first connected to the fifth connecting pipe 321 interface on the outer wall of the filter box 322, and then the gas is transmitted. The filter plate 323 can filter out some large particles of impurities or dust in the gas. After that, the gas is transmitted to the auxiliary cooling box 2, and then the spray plate 324 is activated to perform a preliminary cooling effect on the gas, thereby improving the subsequent cooling effect.

[0028] The first pump body 311 is started, and gas is sprayed into the fixed box 313 through the first connecting pipe 312, so that the gas blows towards the rotating blade 315. When the rotating blade 315 rotates, it drives the first rotating shaft 314 to rotate. The rotation of the first rotating shaft 314 drives the transmission belt 3110 to rotate. The rotation of the transmission belt 3110 drives the second rotating shaft 318 to rotate. During the rotation of the second rotating shaft 318, it drives the stirring blade 319 to rotate, which in turn drives the cooling water in the cooling box 1 to stir and flow. At this time, the high temperature gas is sprayed into the cooling water in the cooling box 1 through the second connecting pipe 316, and the cooling water performs a secondary cooling effect. At this time, the cooling water will always be in an internal flow state due to the action of the stirring blade 319, thus solving the problem of high cooling water temperature near the second connecting pipe 316, thereby improving the cooling effect on the gas.

[0029] Simultaneously, the second pump 3111 is turned on, drawing the cooling water in the cooling tank 1 into the cooler 3113 through the third connecting pipe 3112. This allows the cooling water to perform its cooling function. Then, it is transferred back to the cooling tank 1 through the fourth connecting pipe 3114, thus circulating the water and maintaining its cooling effect. The gas transferred to the cooling water will float upwards and be slowed down by the various baffles 317, extending its cooling time in the cooling water and further improving the cooling effect.
