Embodiment 1

[0029] see figure 1 and figure 2 . figure 1 It is the vertical front view of embodiment 1, figure 2 is the vertical side view. Depend on figure 1 and figure 2 It can be seen that the present invention adopts the direct air-cooling system of natural ventilation, which is composed of exhaust pipe 1, steam distribution pipe 3, air-cooled condenser 5, supporting platform 6, sealing wall 2 and condensation water pipe 7. The system adds a ventilation tower 4, and the ventilation tower 4 is composed of a tower body 4-1 and a pillar 4-2. The pillar 4-2 plays a supporting role in the lower part of the tower body 4-1. The support platform 6 and the air-cooled condenser 5 are arranged inside the ventilation tower 4 . The air-cooled condenser 5 is arranged in an "A" shape and arranged horizontally on the support platform 6. The top of the air-cooled condenser 5 is a steam distribution pipe 3, figure 2 Each "A" shape in the figure represents a row of air-condensing condensers 5...

Embodiment 2

[0033] see Figure 4 . Figure 4 It is the vertical front view of Embodiment 2. The difference from Embodiment 1 is: 1) The main pipe 1-1 of the exhaust pipe 1 is arranged inside the lower pillar 4-2 of the ventilation tower 4; Above the condenser (5), at the air outlet position of the air-cooled condenser (5).

[0034] Others are the same as in Example 1.

Embodiment 3

[0036] see Figure 5 and Image 6 . Figure 5 It is the vertical front view of embodiment 3, Image 6 is a top view.

[0037] Different from Embodiment 1 and Embodiment 2, there are two sets of exhaust pipes 1, which are arranged on both sides of the lower part of the ventilation tower 4, that is, two sets of main pipes 1-1 and two sets of branch pipes 1-2 are arranged. The set of main pipes 1-1 forms two semicircular rings, which are located on the left and right sides of the ventilation tower 4. Apart from this, other parts of Embodiment 3 can be the same as any one of the first two embodiments.

[0038] Embodiment 3 is applicable to the situation where two steam turbines share one ventilation tower 4, and is also applicable to the situation where one steam turbine has two steam outlets.

Abstract

The invention relates to a direct air-cooling system adopting natural ventilation. The direct air-cooling system is used for exhaust condense of turbines of thermal power plants or similar steam driving equipment. The direct air-cooling system comprises a steam exhaust pipeline (1), a steam distribution pipe (3), an air -cooling steam condenser (5), a supporting platform (6) and a condensation water pipeline (7). The direct air-cooling system is characterized in that a ventilation tower (4) is additionally arranged in the system; the supporting platform (6) and the air -cooling steam condenser (5) are arranged in the ventilation tower (4); the system is additionally provided with a louver (8) which is used for adjusting the air flow and horizontally arranged in the ventilation tower (4); a main pipeline (1-1) of the steam exhaust pipeline (1) is arranged on the lower portion of the ventilation tower (4) in an annular mode. According to the direct air-cooling system, the sucking force of the ventilation tower is utilized for driving air to flow, and the purpose of heat convection of the air is achieved through the air -cooling steam condenser. The direct air-cooling system has the advantages that an axial flow fan is omitted, the power consumption of the direct air-cooling system is reduced, and the adverse effects of the fan noise to the environment are avoided.

Description

technical field [0001] The invention relates to a direct air cooling system, which is used for exhaust steam condensation of steam turbines in thermal power plants or similar steam-driven equipment. Background technique [0002] In the process of thermal power generation, the exhaust steam discharged from the low-pressure cylinder of the steam turbine needs to be condensed into water and then sent back to the boiler for recycling. In order to save water resources, many power plants use direct air cooling system to condense exhaust steam. [0003] At present, the direct air-cooling system consists of exhaust pipes, air-cooled condensers, axial fans, and supporting platforms. Since the cold air is exchanged through the air-cooled condenser by means of forced ventilation, the system needs to be equipped with many large-scale ventilation equipment, such as a large-diameter axial flow fan and its matching gear box and motor; the layout of the air-cooled condenser On a rectangul...
