Description

Technical Field

[0001] The utility model relates to the technical field of atomizing cooling devices, in particular to a spray atomizing cooling device for an intermediate cooling tower between two turbines and one tower. Background Technique

[0002] With the intensification of the world energy shortage and competition, it has become increasingly important for thermal power plants, which are large energy consumers, to save energy and reduce consumption. Reducing the power generation cost and improving the operating economy of units have become the top priorities of power generation enterprises. Currently, the prominent problem in the operation of domestic and foreign units is the poor operation condition of the cold end system, which seriously affects the operating economy of the units. Nowadays, the main forms adopted by the cold end systems of steam turbine generator units are direct air cooling systems, indirect air cooling systems, and wet cooling systems. The above three forms of cold end systems exist in major domestic and foreign power generation enterprises, but each of the above three systems has its own problems. Among them, the direct air cooling system and the indirect air cooling system are greatly affected by the environment, and the wet cooling system is greatly affected by the water source. Restricted by factors such as the above-mentioned technology and equipment level, the cold end systems of steam turbine generator units in areas with less water sources are basically direct air cooling systems or indirect air cooling systems. However, the direct air cooling system and the indirect air cooling system generally have the problem of high back pressure of the unit in high-temperature weather, showing poor economy in harsh environments. With the increasing requirement of reducing the power generation cost, there is an urgent need for innovation in the cold end systems of steam turbine generator units.

[0003] However, for traditional equipment, the cold end systems of steam turbine generator units in areas with less water sources are basically direct air cooling systems or indirect air cooling systems. However, the direct air cooling system and the indirect air cooling system generally have the problem of high back pressure of the unit in high-temperature weather, showing poor economy in harsh environments. With the increasing requirement of reducing the power generation cost, improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems raised in the above background technique.

[0005] The utility model adopts the following technical solutions: a spray atomization cooling device for an indirect cooling tower with two machines and one tower, including a tower body. A support structure is fixedly installed at the bottom end of the tower body. An indirect cooling tube bundle is fixedly installed on the surface of the support structure. A cooling structure is fixedly installed inside the tower body. An annular pipe I is sleeved inside the tower body. One end of the annular pipe I is fixedly installed with a connecting pipe I. A valve is fixedly installed at the top end of the annular pipe I. An annular pipe II is fixedly installed at the top end of the valve.

The rear end of the grooves penetrates through the surface of the connecting pipe II. Here, the design of the arc-shaped grooves can make the installation of the nozzle I more convenient and fast, and also helps to improve the tightness of the connection. The two groups of grooves increase the stability and reliability of the connection. The penetrating design facilitates the operation during the installation and maintenance process.

The box door facilitates the cleaning and replacement of the filter screen. The combination of the hydraulic cylinder, the moving block and the conical nozzle can realize the automatic cleaning of the filter screen and improve the maintenance efficiency of the equipment. The rubber telescopic pipe is connected to the air compressor to provide a power source for cleaning.

[0011] Preferably, the number of the conical nozzles is multiple and they are arranged in an array on the surface of the moving block. The output end of the air compressor is fixedly connected to the other end of the rubber telescopic pipe. Here, the multiple conical nozzles arranged in an array can improve the cleaning effect on the filter screen and ensure the cleanliness of the filter screen. The air compressor provides compressed air for the conical nozzles through the rubber telescopic pipe, ensuring the power and effect of cleaning.

[0012] Preferably, the number of the hydraulic cylinders is two and they are symmetrically distributed at the top of the filter box. The moving block and the conical nozzles are both sleeved inside the filter box. Sealing rings are fixedly installed on the outer surface of the box door and inside the second connecting pipe. The sealing rings are closely attached to the filter box and the first nozzle. Here, the two symmetrically distributed hydraulic cylinders can make the movement of the moving block more stable and improve the stability of cleaning. The setting of the sealing rings ensures the sealing performance between the filter box, the first nozzle and the second connecting pipe, prevents leakage, and improves the working efficiency and reliability of the whole device.
