Description

Technical Field

[0001] This utility model relates to the field of foam treatment technology for power plant absorption towers, and in particular to a foam treatment device for absorption towers. Background Technology

[0002] Wet flue gas desulfurization (FGD) is the most commonly used FGD process in coal-fired power plants. During operation, foam frequently forms in the absorber tower. Existing absorber towers only have overflow devices at their high-level discharge outlets, but the inlet of these overflow devices is designed to be below the lowest operating liquid level in the absorber tower. Therefore, relying solely on the overflow device makes it difficult to discharge the foam within the absorber tower. Boiler start-up and shutdown, fuel combustion, and long-term operation of the absorber tower all contribute to foam generation. Failure to promptly discharge this foam can lead to decreased desulfurization efficiency, difficulties in gypsum dehydration, and even necessitate boiler shutdown for treatment.

[0003] Chinese Patent No. CN215693093U discloses a foam treatment device for an absorption tower, including a support frame disposed on the side wall of the absorption tower and a drive motor disposed on the support frame; a receiving unit connected to the drive motor, which includes a receiving component and a diverting component, the receiving component and the diverting component being connected in cooperation; and a discharge unit connected to the diverting component, including a confluence component and a discharge component, the confluence component and the discharge component being in communication. This utility model is disposed on the side wall of the absorption tower. The receiving unit is driven by the drive unit. The receiving unit is a structural component that scoops out foam from inside the absorption tower. The scooped-out foam is collected in the discharge unit and discharged by the discharge unit to the outside of the absorption tower for centralized treatment. This physical defoaming method can not only avoid environmental pollution caused by defoaming agents, but also effectively reduce defoaming costs.

[0004] The existing foam treatment device for absorption towers has a fixed scoop bucket, which makes it inconvenient to adjust the position of the scoop bucket according to the thickness of the foam, reduces the amount of foam scooped at one time, reduces the effectiveness of the scoop bucket during use, and causes foam to accumulate on the absorption tower, reducing the foam treatment effect of the absorption tower and the practicality of the foam treatment device.

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] Example 1

[0026] like Figure 1 - Figure 3 As shown, the present invention proposes an absorption tower foam treatment device, comprising: an absorption tower body 1, foam treatment components 2, and a discharge pipe 4; the foam treatment components 2 are provided in four sets, each set being connected to the absorption tower body 1; each set of foam treatment components 2 includes a rotating rod 201, a fixed rod 202, an adjusting rod 203, a mounting plate 204, a fixing plate 205, and a connector; the rotating rod 201 is connected to the inner wall of the absorption tower body 1, one end of the rotating rod 201 is connected to the fixed rod 202, the fixed rod 202 is connected to the adjusting rod 203, the adjusting rod 203 is connected to the mounting plate 204, the mounting plate 204 is connected to the fixing plate 205, and the connector is connected to one end of the mounting plate 204 and the fixed rod 202; the discharge pipe 4 is connected to the absorption tower body 1. The fixed rod 202, adjusting rod 203, mounting plate 204 and fixing plate 205 are used together to facilitate the up and down adjustment of the position of the scoop 206, and to make it easy to adjust the position according to the foam, thereby improving the foam treatment effect and enhancing the use of the absorption tower foam treatment device.

[0027] To further explain, the fixing rod 202 is hollow inside, with an open end for connecting the adjusting rod 203. The mounting plate 204 has a pre-drilled mounting hole at its mounting end, and the fixing plate 205 has multiple pre-drilled connection holes. The pre-drilled mounting hole and any one of the pre-drilled connection holes are aligned for connecting the mounting plate 204 and the fixing plate 205. A bolt is used, with one end passing through the pre-drilled mounting hole and the pre-drilled connection hole, and then locked in place, allowing the mounting plate 204 and the fixing plate 205 to be installed and detachably connected.

[0028] To further explain, one side of the discharge pipe 4 is connected to the installation pipe 5, and the installation pipe 5 is connected to the backwash water pump 6 for cleaning the foam treatment component 2. After the foam treatment work of the absorption tower is completed, the backwash water pump 6 is used. The inlet end of the backwash water pump 6 is connected to a water pipe, and the inlet end of the water pipe is connected to a tap, thereby starting the backwash water pump 6 and turning on the tap. Before use, the backwash water pump 6 is connected to the control system and power supply through wires. Tap water is delivered to the installation pipe 5 through the water pipe and the backwash water pump 6. The installation pipe 5 is connected to the discharge pipe 4. The tap water flows back from the discharge pipe 4 to the connection of components such as the diversion pipe 207 and the scoop 206, so as to clean the components of the foam treatment component 2 and improve the functionality of the absorption tower foam treatment device.

[0029] Example 2

[0030] like Figure 1 As shown, the present invention proposes an absorption tower foam treatment device. Based on the above embodiments, this embodiment also details the specific components of the connectors and their assembly methods.

[0031] Further explanation: the connecting components include a scoop 206, a diversion pipe 207, a confluence channel 208, a connecting pipe 209, and a servo motor 210; one end of the scoop 206 is connected to the diversion pipe 207, one end of the diversion pipe 207 is connected to the confluence channel 208, and the connecting pipe 209 is connected to the confluence channel 208; the drive end of the servo motor 210 passes through the absorption tower body 1 and is connected to the rotating rod 201, and the servo motor 210 is connected to the outer wall of the absorption tower body 1; the inner wall of the absorption tower body 1 is connected to the central pipe 3, and the central pipe 3 is connected to the connecting pipe 209; one end of the discharge pipe 4 passes through the absorption tower body 1 and is connected to the central pipe 3, and the other end of the discharge pipe 4 is connected to the return component. Servo motor 210 is connected to the control system and power supply via wires. Starting servo motor 210 causes the rotating rod 201 to rotate. The rotating rod 201 drives the fixed rod 202, adjusting rod 203, mounting plate 204, and fixed plate 205 to rotate, thereby causing the scoop 206 to rotate and collect foam. The collected foam is transported to the concentrator 3 through the drainage pipe 207, confluence channel 208, and connecting pipe 209. The concentrator 3 is connected to the discharge pipe 4, thus transporting the foam into the discharge pipe 4. The discharge pipe 4 is connected to the return assembly, which includes an outlet component, discharge pipe, defoaming treatment component, return component, guide component, and discharge... The system includes a discharge pipe, an outlet pipe, and a discharge pipe. The discharge pipe connects to a defoaming treatment component, which in turn connects to a return component. The return component is connected to the absorption tower body 1, thus treating the foam and returning it to the absorption tower body 1. The foam is then transported to the return component and then back to the absorption tower body 1. All these processing steps utilize publicly available technologies and will not be described in detail here. A valve is installed at the connection end between the discharge pipe 4 and the outlet pipe. When the absorption tower foam treatment device is cleaning, the valve is closed to prevent cleaning water from being transported to the return component, facilitating the connection and cooperation of the components of the absorption tower foam treatment device.

[0032] The working principle of this utility model is as follows: When the position of the scoop 206 needs to be adjusted in the absorption tower foam treatment device, firstly, the operation of the absorption tower foam treatment device is turned off, and the original connection position of the mounting plate 204 and the fixing plate 205 is disassembled. Then, according to the foam treatment requirements, the lengths of the fixing rod 202 and the adjusting rod 203 are adjusted. The adjusting rod 203 drives the mounting plate 204, and the reserved mounting hole at one end of the mounting plate 204 is adjusted to correspond with the corresponding reserved connection hole. Then, one end of the bolt is passed through the reserved mounting hole and the reserved connection hole, and the nut and the bolt are threaded together, thereby installing and connecting the mounting plate 204 and the fixing plate 205, so as to fix the length of the adjusting rod 203 and the fixing rod 202, and fix the position of the scoop 206. After the position of the scoop 206 is fixed, the absorption tower foam treatment device is put into operation, thereby treating the foam in the absorption tower and conveniently improving the use effect of the absorption tower foam treatment device.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
