Description

Technical Field

[0001] The utility model relates to the technical field of indirect air cooling towers, in particular to an air duct for an indirect air cooling system. Background Art

[0002] With the rapid development of the power industry in northwestern my country, power plants require sufficient water for cooling equipment. While these regions are rich in resources like coal, they are also in dire need of water. Indirect air cooling technology, due to its increasing maturity and significant water-saving effects, is increasingly being adopted by power plants in these regions. Indirect air cooling, a type of air cooling technology, consists of the following components: a heat exchange tube bundle, a cooling triangle, a louver actuator, an underground water tank, an elevated water tank, a widening platform, X-pillars, a circulating water system, a water charging and makeup system, an air pipe system, a cleaning pipe system, an instrumentation and control system, and an electrical system.

[0003] Traditional indirect air cooling systems typically place air ducts above the widening platform, that is, outside the intercooler tower of the air cooling system. This takes up more space and increases construction costs. Furthermore, the traditional layout method can easily cause pipes and instrumentation to freeze in the extreme weather conditions common in northern my country during winter, hindering on-site inspections and operations. Improving the antifreeze effect of pipes and related equipment and increasing the convenience of on-site staff are urgent issues that need to be addressed. Utility Model Content

[0004] In response to the deficiencies of the existing technology, the utility model provides an air duct for an indirect air cooling system, which solves the problem that the traditional layout method is prone to causing pipes and instrument equipment to freeze in the extreme weather conditions common in northern my country in winter, which is not conducive to on-site inspection operations by on-site staff.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an air duct for an indirect air cooling system, comprising an air duct, a widening platform, and an indirect cooling tower wall. The bottom of the widening platform is fixedly connected to a first inclined support structure, the bottom of the first inclined support structure is fixedly connected to an indirect cooling tower X-pillar. A first section steel and a third section steel are welded to the bottom of the widening platform. A second section steel is welded to the lower end of the first section steel. The first and second section steels form a first air duct bracket. A fourth section steel is welded to the lower end of the third section steel. The fourth and fourth section steels form a second air duct bracket. The upper ends of the second and fourth section steels are each provided with a pipe clamp, and the air duct is sleeved inside the pipe clamp.

[0006] Preferably, one end of the air duct extends upward and is fixedly connected to the inner side of the intercooling tower wall, the other end of the air duct is fixedly connected to a branch pipe, one end of the branch pipe is bent downward, one end of the branch pipe is fixedly connected to a cooling triangle, and the bent part at one end of the air duct is fixedly connected to instrument equipment.

[0007] Preferably, the top of the intercooling tower X-pillar is fixedly connected to a maintenance operation platform, and the bottom of the maintenance operation platform is fixedly connected to a second oblique support structure.

[0008] Preferably, a plurality of first air duct supports are welded to the bottom of the widening platform.

[0009] Preferably, one end of the widened platform is connected to the upper end of the intercooling tower X-pillar, the bottom of the widened platform is fixed on the intercooling tower X-pillar through a first oblique support structure, and the maintenance operation platform is fixed on the intercooling tower X-pillar through a second oblique support structure.

[0010] Preferably, the air duct is arranged below the widened platform and passes through the wall of the intercooler tower into the intercooler tower, and the branch pipe is connected to the top pipe opening of the cooling triangle.

[0011] The utility model provides an air duct for an indirect air cooling system. Compared with the prior art, it has the following advantages:

[0012] 1. An air duct for an indirect air cooling system is arranged under a widened platform, i.e., inside the intercooler tower of the air cooling system, through an air duct with electric heating. A first air duct bracket and a second air duct bracket secure the air duct using the bottom of the widened platform to form a stable structure. This saves space, reduces construction costs, optimizes air flow, and improves the antifreeze performance of the pipeline and instrument equipment. At the same time, the addition of a maintenance operation platform improves the convenience of operation for on-site staff.

[0013] 2.

It includes an air duct 1, a widening platform 2 and an intercooling tower wall 5. The bottom of the widening platform 2 is fixedly connected to a first oblique support structure 11, and the bottom of the first oblique support structure 11 is fixedly connected to the intercooling tower X-pillar 3. The first oblique support structure 11 is used to support the widening platform 2 and connect the widening platform 2 and the intercooling tower X-pillar 3. The bottom of the widening platform 2 is welded with a first section steel 13 and a third section steel 16. The lower end of the first section steel 13 is welded with a second section steel 14. The first section steel 13 and the second section steel 14 are welded to each other to form a first air duct bracket 8. The lower end of the third section steel 16 is welded with a fourth section steel 17. The third section steel 16 and the fourth section steel 17 are welded to each other to form a second air duct bracket 9. The upper ends of the second section steel 14 and the fourth section steel 17 are welded with a pipe hoop 15. The air duct 1 is sleeved inside the pipe hoop 15. The first air duct bracket 8 and the second air duct bracket 9 are used to support the air duct 1 arranged inside the pipe hoop 15, so that the air duct 1 can be fixed to the bottom of the widening platform 2.

[0021] See also Figure 1-4One end of the air duct 1 extends upward and is connected to the inner side of the intercooling tower wall 5, and the other end of the air duct 1 is fixedly connected to a branch pipe 10. One end of the branch pipe 10 is bent downward, and one end of the branch pipe 10 is fixedly connected to a cooling triangle 6. The bent part at one end of the air duct 1 is fixedly connected to an instrument equipment 7. The top of the intercooling tower X pillar 3 is fixedly connected to a maintenance operation platform 4. The maintenance operation platform 4 is used to facilitate workers to operate. The bottom of the maintenance operation platform 4 is fixedly connected to a second inclined support structure 12. Several first air duct brackets 8 are welded to the bottom of the widening platform 2. One end of the widening platform 2 is connected to the upper end of the intercooling tower X pillar 3.

The air duct 1 is arranged below the widening platform 2 and passes through the intercooling tower wall 5 into the intercooling tower. The branch pipe 10 is connected to the top pipe mouth of the cooling triangle 6.

[0022] When wind passes through the gaps in the pipe, it can take away the heat of the hot water in the pipe, cooling the water inside the pipe. Since the air with high temperature has a smaller density, it will flow upward, while the cold air has a larger density and will flow downward. This natural convection phenomenon helps to form air flow inside the cooling tower and promotes the heat exchange process. The air duct 1 with electric heating is arranged under the widening platform 2, that is, inside the intercooler of the air cooling system. The first air duct bracket 8 and the second air duct bracket 9 use the bottom of the widening platform 2 to fix the air duct 1 to form a stable structure, saving space, reducing construction costs, optimizing air flow, and improving the anti-freeze performance of the pipeline and instrument equipment 7. At the same time, by adding a maintenance operation platform 4, the operation convenience of on-site staff is improved.
