Description

Technical Field

[0001] This utility model relates to the field of steam turbine technology, and in particular to a water spray atomization temperature control device for steam turbines in thermal power plants. Background Technology

[0002] The steam turbine water spray atomization temperature control device in thermal power plants is a device used to regulate the intake air temperature of steam turbines. It mainly uses water spray atomization technology to cool down the steam turbine and ensure that the steam turbine operates within a suitable temperature range, thereby improving operating efficiency and safety. The device generally consists of two main parts: a frame and spray heads.

[0003] The waste of water resources is a significant drawback of water spraying atomization temperature control devices in thermal power plant turbines. Specifically, this drawback manifests in the following ways: During the spraying cooling process, water is sprayed into the airflow in the form of mist or fine particles. Most of the water evaporates or is lost into the air and cannot be recovered in time. This means that most of the water is wasted during the cooling process and cannot be recycled. This waste is particularly prominent in water-scarce areas and may increase the water costs of thermal power plants. Since the water cannot be recycled and reused, the water spraying atomization device needs to be constantly replenished, which will increase the operating costs of thermal power plants. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a water spraying atomization temperature control device for steam turbines in thermal power plants. The device effectively collects the sprayed water mist through a water collection net and guiding components, avoiding water waste. The collected water is systematically collected through a water collection pipe, guiding pipe, collection tray, and collection box, and then recycled, solving the problem of water resource loss in traditional systems.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water spray atomization temperature control device for steam turbines in thermal power plants, comprising a water spray atomization device frame, a spray group at the top of the water spray atomization device frame, a water storage tank on the side of the water spray atomization device frame, a water pump on the side wall of the water storage tank, a flow meter connected to the output end of the water pump, the output end of the flow meter connected to the spray group, a collection component installed opposite the water spray atomization device frame, a guide component on the collection component, the collection component collecting water mist, and the guide component collecting water.

[0006] As a preferred technical solution of this utility model, the collection component includes a support rod placed opposite the frame of the water spray atomizing device, an installation frame connected to the support rod, a water collection mesh installed on the installation frame, and a support base fixed to the bottom end of the support rod.

[0007] As a preferred embodiment of this utility model, the water collection mesh is configured as a cotton cloth layer, and the water collection mesh is set in the spray area corresponding to the spray group.

[0008] As a preferred embodiment of this utility model, the guiding component is disposed at the bottom end of the water collection mesh, and the guiding component guides and collects the water dripping from the water collection mesh.

[0009] As a preferred technical solution of this utility model, the guiding component includes a water collection pipe disposed at the bottom end of the water collection mesh and installed on the mounting frame, a first guiding pipe connected to the water collection pipe at one end, a collection tray connected to the other end of the first guiding pipe, a second guiding pipe connected to the collection tray at one end, and a collection box connected to the other end of the second guiding pipe.

[0010] As a preferred technical solution of this utility model, the water collection pipe is installed at an angle on the mounting frame, and the upper end of the water collection pipe is provided with a groove corresponding to the bottom end of the water collection mesh.

[0011] As a preferred embodiment of this utility model, the top end of the first guide pipe is connected to the bottom end of the water collection pipe through the mounting frame, the other end of the first guide pipe is fixedly installed with the support rod, and the bottom end is placed in the collection tray.

[0012] As a preferred embodiment of this utility model, the collecting tray is provided with an annular cavity, and the collecting tray is connected to the collecting box through a second guide tube.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0014] Traditional water spray cooling devices spray a large amount of water into the airflow in the form of mist or fine particles during the cooling process. Most of the water evaporates or is lost into the air and cannot be recovered in time. This device effectively collects the sprayed water mist through a water collection net and guiding components, avoiding water waste. The collected water is systematically collected through water collection pipes, guiding pipes, collection trays, and collection boxes for recycling, solving the problem of water loss in traditional systems.

[0015] Improving water resource recycling efficiency: The device cleverly utilizes an inclined water collection pipe and guide pipe system, making the water collection process more efficient. After the water mist is absorbed by the water collection mesh, the water droplets flow smoothly into the water collection pipe and are guided layer by layer through multiple guide pipes to the collection box for centralized collection. This design ensures that the water source can be recycled in a timely manner after spray cooling, avoiding excessive water evaporation and waste. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified. Example

[0023] like Figure 1-5 As shown, a water spray atomization temperature control device for steam turbines in thermal power plants includes a water spray atomization device frame 1, a spray group 2 is provided at the top of the water spray atomization device frame 1, a water storage tank 4 is provided on the side of the water spray atomization device frame 1, a water pump 5 is provided on the side wall of the water storage tank 4, a flow meter 3 is connected to the output end of the water pump 5, the output end of the flow meter 3 is connected to the spray group 2, a collection component 6 is installed on the opposite side of the water spray atomization device frame 1, a guide component 7 is provided on the collection component 6, the collection component 6 collects water mist, and the guide component 7 collects water.

[0024] The collection component 6 includes a support rod 61 placed opposite the water spray atomizing device frame 1, an installation frame 62 connected to the support rod 61, a water collection mesh 63 installed on the installation frame 62, and a support base 64 fixed to the bottom of the support rod 61.

[0025] Workers use support base 64 and support rod 61 to arrange water collection mesh 63 opposite water spray atomizing device frame 1. A steam turbine that needs temperature control is placed between water spray atomizing device frame 1 and water collection mesh 63. Spray cooling from spray group 2 is sprayed onto water collection mesh 63 through the steam turbine for absorption.

[0026] It is worth noting that the water collection mesh 63 is set as a cotton cloth layer, and the water collection mesh 63 is set in the spraying area of ​​the spray group 2.

[0027] The guiding component 7 is located at the bottom end of the water collection mesh 63. The guiding component 7 guides and collects the water dripping from the water collection mesh 63. The guiding component 7 includes a water collection pipe 71 located at the bottom end of the water collection mesh 63 and mounted on the mounting frame 62, a first guiding pipe 72 connected to the water collection pipe 71 at one end, a collection tray 73 connected to the other end of the first guiding pipe 72, a second guiding pipe 74 connected to the collection tray 73 at one end, and a collection box 75 connected to the other end of the second guiding pipe 74.

[0028] After the water mist is collected by the water collection net 63, it drips from the bottom into the water collection pipe 71. Because the water collection pipe 71 is set at an angle, the water source always flows to the lower part of the water collection pipe 71, and is then guided to the collection tray 73 through the first guide pipe 72. The water source flows into the collection box 75 through the second guide pipe 74 for collection.

[0029] It is worth noting that the water collection pipe 71 is installed at an angle on the mounting frame 62. The upper end of the water collection pipe 71 has a slot that corresponds to the bottom end of the water collection mesh 63. The angled design ensures that the water flow can naturally flow to the lower end of the pipe, avoiding water stagnation inside the water collection pipe. This is achieved by using gravity to help the water source flow along the pipe to a lower position, thereby improving the collection efficiency and ensuring that the water source flows to the collection system in a timely manner.

[0030] The top end of the first guide pipe 72 passes through the mounting frame 62 and connects to the bottom end of the water collection pipe 71. The other end of the first guide pipe 72 is fixedly installed with the support rod 61, and the bottom end is placed in the collection tray 73. By fixing the first guide pipe 72 to the support rod 61, the position of the first guide pipe 72 can be ensured to be stable, thereby ensuring the smooth guidance of water flow. The bottom end of the pipe is located in the collection tray 73, so that the water flow can be concentrated in the collection tray 73 after passing through the first guide pipe 72, and will not be dispersed or deviated.

[0031] The collection tray 73 has an annular cavity, which allows water to be more effectively concentrated in the center of the collection tray 73, avoiding water overflow along the edge or uneven collection. The collection tray 73 is connected to the collection box 75 through the second guide pipe 74 to ensure stable entry into the collection box and maximize the recycling of water resources.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as defined by the appended claims and their equivalents.
