Description

Technical Field

[0001] This utility model relates to the field of thermal energy technology, and in particular to a demineralized water spray device for the inlet of the exhaust device of an air-cooled unit. Background Technology

[0002] Air-cooled units, especially large direct air-cooled units, are the main type of power plants in coal-rich and water-scarce areas of my country. Compared with conventional water-cooled units, air-cooled units have significant water-saving effects, but their operating economy is generally lower. The core reason is that their operating back pressure (exhaust steam pressure) is higher and fluctuates greatly with environmental changes. The heat exchange medium of the air-cooled system is air, whose specific heat capacity and heat transfer coefficient are much lower than those of water, resulting in relatively low heat exchange efficiency of the air-cooled condenser. During hot and windy summer weather, the exhaust pressure of air-cooled units increases significantly, leading to the following problems: 1. Decreased unit efficiency: According to the Rankine cycle principle, increased exhaust pressure directly reduces the ideal enthalpy drop of the turbine, increases unit energy consumption, and worsens operating economy; 2. Limited output: To prevent excessively high exhaust pressure from endangering unit safety (such as low-pressure cylinder last-stage blade flutter), the unit load often needs to be reduced during high-temperature periods, affecting the power grid's supply capacity; 3. Operational safety challenges: High back pressure operation increases the energy consumption of air-cooled fans and is prone to causing the air-cooled island to freeze in winter; Therefore, improvements are needed to address these issues.

The first connecting pipe 2, the second connecting pipe 4, and the water pipe 10 facilitate the delivery of demineralized water, respectively connecting the water storage tank 1 to the high-pressure pump 3, the high-pressure pump 3 to the four-way pipe 5, and the four-way pipe 5 to the arc-shaped pipe. The liquid is connected to nozzle 8; the high-pressure pump 3 facilitates the provision of high-pressure power to the demineralized water, ensuring that the demineralized water can be atomized and sprayed through nozzle 9 to meet the spray pressure requirements; the four-way pipe 5 facilitates the diversion of demineralized water, distributing the demineralized water delivered by the high-pressure pump 3 to multiple spray components to achieve multi-directional spray supply; the spray component includes a positioning block 6 installed at the other end of the four-way pipe 5, with rotating rings 7 rotatably connected to both ends of the positioning block 6, and damping provided at the rotatable connection between the rotating rings 7 and the positioning block 6; arc-shaped pipes 8 are installed on the outside of the two rotating rings 7, and the two arc-shaped pipes 8 form a circle; the positioning block 6 facilitates the support of the rotating rings 7; the rotating rings 7 facilitate the control of the angle adjustment of the arc-shaped pipes 8; the arc-shaped pipes 8 facilitate the formation of a ring structure to expand the spray range.

[0015] In this invention, multiple equidistant nozzles 9 are installed on the inner sides of two arc-shaped pipes 8, and a water pipe 10 is installed on the outer sides of the two arc-shaped pipes 8. The other end of the water pipe 10 is connected to a four-way pipe 5. The nozzles 9 facilitate liquid atomization. The nozzles 9 are of the LNN-W series. A connecting rod 11 is installed at one end of the four-way pipe 5. The connecting rod 11 is L-shaped, and two arc-shaped positioning plates 12 are movably hinged to the other end of the connecting rod 11. The two positioning plates 12 form a circle.

Through the cooperation of the positioning plate 12, the arc-shaped telescopic ring 13, and the moving ring 14, the device is installed and fixed at the inlet of the air-cooled unit's exhaust system. Then, the telescopic length of the arc-shaped telescopic ring 13 and the position of the moving ring 14 are adjusted according to the inlet specifications to ensure stable installation. Next, according to actual spraying requirements, the rotating rings 7 at both ends of the positioning block 6 are rotated to adjust the spray angle of the arc-shaped pipe 8.

During the spraying process, most of the mist leakage is avoided by the arc-shaped telescopic ring 13. Finally, all electrical equipment is powered off.
