Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of GGH equipment of a desulfurization system of a power plant, and particularly relates to a GGH anti-clogging flushing device. Background Art
[0002] To increase exhaust gas temperature and prevent low-temperature corrosion, most wet flue gas desulfurization systems are equipped with a flue gas heater (GGH). In thermal power plant wet flue gas desulfurization systems, fly ash from the electrostatic precipitator and clean flue gas carry slurry from the absorber. Under the high temperature of the raw flue gas, insoluble sulfates and silicates form on the surface of the GGH. These long-term accumulations can clog the GGH. When the GGH pressure differential increases, the lack of online high-pressure water flushing leads to increased scaling and resistance, making it difficult to achieve high desulfurization operation rates.
[0003] Therefore, it is necessary to design a GGH anti-clogging flushing device to flush the internal fins of the GGH and reduce scaling efficiently. Utility Model Content
[0004] In response to the problems of the prior art, the purpose of the present invention is to provide a GGH anti-clogging flushing device to solve the problem that insoluble sulfates and silicates are formed on the surface of GGH, which accumulate and clog the GGH over a long period of time. When the pressure difference of GGH increases, online high-pressure water flushing is not adopted, resulting in increased scaling, gradually increased resistance, and difficulty in improving the desulfurization commissioning rate.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A GGH anti-clogging flushing device includes a guide rail, which is fixed on both sides of the inner wall of the GGH. A fixed bracket is provided on the guide rail, a hook ring is provided on the left side of the fixed bracket, a telescopic rod is connected to the hook ring, a flushing water pipe is provided on the upper part of the fixed bracket, a plurality of nozzles are provided on the flushing water pipe, a roller is provided on the lower part of the fixed bracket, the roller drives the fixed bracket, the flushing water pipe and the nozzle to slide on the guide rail, a fixing clamp is provided on the side of the guide rail, a hose is provided on the fixing clamp, one end of the hose is connected to the flushing water pipe, and the other end of the hose passes through the external water pipe opening and is connected to an external water source.
[0007] More preferably, a hook is provided at one end of the telescopic rod, and the telescopic rod is hung on the hook ring of the fixing bracket through the hook.
[0008] More preferably, the hose and the flushing water pipe are made of corrosion-resistant and high-temperature-resistant materials.
[0009] More preferably, the nozzle is a high-pressure water jet.
[0010] More preferably, when the telescopic rod is pulled forward to drive the fixing bracket and the flushing water pipe, the hose is also extended in the fixing clamp.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This utility model provides a GGH anti-clogging flushing device with a simple overall structure and easy installation. During use, the worker only needs to control the telescopic rod to move the fixed bracket, flushing water pipe, and nozzle, thereby changing the flushing area and achieving a complete flushing area without blind spots. This avoids the need for workers to reach into the GGH with a handheld high-pressure water gun to flush, improving the worker's working environment and increasing work efficiency.
[0013] 2. The hose and flushing water pipe of this utility model are made of corrosion-resistant and high-temperature resistant materials, so flushing can be performed even when there is high-temperature flue gas during GGH operation.
[0014] 3. When the telescopic rod is pulled to move the fixed bracket and flush the water pipe, the hose also extends in the fixing clamp. The fixing clamp also fixes and stores the hose, making it easy to collect the hose. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-4 The figure shows a GGH anti-clogging flushing device, comprising a guide rail 2 welded to the inner wall of the GGH. A fixed bracket is attached to the guide rail. A hook ring 11 is provided on the left side of the fixed bracket 3. A telescopic rod 1 is connected to the hook ring 11. The telescopic rod 1 has a hook at one end, and the hook is used to hook the telescopic rod 1 to the hook ring 11 of the fixed bracket 3. A flushing pipe 8 is installed above the fixed bracket 3. The flushing pipe 8 is equipped with several nozzles 7. These nozzles 7 use high-pressure water jets to ensure a clean flush. A roller 4 is installed below the fixed bracket 3, which drives the fixed bracket 3, flushing pipe 8, and nozzles 7 to slide along the guide rail 2. A fixing clamp 6 is welded to the side of the guide rail 2. A hose 5 is attached to the clamp 6, which both secures and stores the hose 5. One end of the hose 5 is connected to the flushing pipe 8, and the other end passes through an opening 9 for the external water pipe and is connected to an external water source. The hose 5 and flushing pipe 8 are made of corrosion-resistant and high-temperature resistant materials to reduce the impact of high-temperature fumes.
[0023] During use, the staff hangs the telescopic rod 1 on the hook ring 11, and adjusts the flushing area by pulling the telescopic rod 1 to move the position of the fixed bracket 3, the flushing water pipe 8 and the nozzle 7. At this time, the hose 5 is also extended in the fixed clamp 6, and the flushing water enters the hose 5 through the external water pipe opening 9, and then enters the flushing water pipe 8, and is sprayed onto the surface of the fin 10 through the nozzle 7, so as to achieve a clean flushing area without dead angles, efficiently reduce scaling, avoid the situation where the staff enters the GGH internal flushing with a high-pressure water gun, improve the working environment of the staff, and improve the working efficiency.
