Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air cooling tower radiator cleaning equipment, and particularly relates to an air cooling tower finned tube cleaning system. BACKGROUND

[0002] A natural draft direct air cooling system (referred to as "NDC system") refers to steam turbine exhaust steam being sent to an air cooling radiator through an exhaust steam pipeline, and the air cooling radiator being arranged in a natural draft air cooling tower, so that cold air flows through the surface of the radiator by using the draft of the tower cylinder, so that the steam in the radiator is condensed. The NDC system is very close to the ACC system, only the ventilation form is different, the ACC system adopts mechanical ventilation, and the NDC system adopts natural ventilation. The main feature of changing the ventilation form from mechanical ventilation to natural ventilation is energy saving and consumption reduction, and reducing the plant power rate. The NDC system includes, in addition to the main equipment, an exhaust steam pipeline, a natural draft cooling tower, a direct air cooling condenser and its auxiliary facilities. The air cooling condenser is a three-prism in space, and the horizontal section is an isosceles triangle (also referred to as a cooling triangle). The finned tube is arranged at both sides of the cooling triangle, the heat exchange fins on the finned tube can increase the cooling area when the natural wind flows through, and improve the cooling effect. The louvers are installed at the air inlet side of the cooling triangle, and are used for regulating the air inlet amount. The low-temperature ambient air flows into the finned tube in the cooling triangle through the louvers, and can reduce the temperature of the circulating water in the finned tube through heat exchange with the finned tube.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the scope of protection of the present application.

[0028] As Figures 1-6As shown, the air cooling tower finned tube cleaning system disclosed in the present application is used for cleaning the finned tube bundle 21 in the cooling triangle 2 under the air cooling tower widening platform 1, which comprises three positioning guide columns 3, the three positioning guide columns 3 are respectively fixedly installed on the three corners inside the cooling triangle 2 along the vertical direction, a first working platform 4 is horizontally arranged inside the cooling triangle 2, the shape of the first working platform 4 is the same as that of the cooling triangle 2, and a guide groove wheel 5 is respectively arranged on the three corners of the first working platform 4, the three guide groove wheels 5 are respectively movably installed on the three positioning guide columns 3;

[0029] Two lateral installation plates 6 are respectively arranged on the two waists of the first working platform 4 and extend upwards, a plurality of spray heads 7 are uniformly arranged on each lateral installation plate 6 along the length direction thereof, and the water outlet ends of the spray heads 7 are all directed to the finned tube bundle 21 at the corresponding position; a clean water tank 8 is arranged at the center of the first working platform 4, a water pump 9 is arranged in the clean water tank 8, and the water pump 9 in the clean water tank 8 is connected with all the spray heads 7 through a water supply pipeline 10;

[0030] The upper side of the first working platform 4 is connected with a hoisting unit 11 arranged on the widening platform 1, and the hoisting unit 11 can adjust the vertical position of the first working platform 4 in the cooling triangle 2.

[0031] In the above embodiment, the shape of the first working platform 4 is an isosceles triangle which is the same as that of the cooling triangle 2, so that when the first working platform 4 is arranged inside the cooling triangle 2, the spray heads 7 on the two waists of the first working platform 4 can be just directed to the finned tube bundle 21 on the two waists of the cooling triangle 2, so that when the first working platform 4 moves along the vertical direction, the finned tube bundle 21 on the cooling triangle 2 can be comprehensively cleaned.

[0032] Since the first working platform 4 is arranged inside the cooling triangle 2, in order to avoid the first working platform 4 from touching the fins of the finned tube bundle 21 or the louvers of the louvre during the movement, a gap is arranged between the edge of the first working platform 4 and the inner wall of the cooling triangle 2, if the first working platform 4 is not limited during the movement with the hoisting unit 11, the first working platform 4 may swing in the cooling triangle 2 and collide with the fins of the finned tube bundle 21 or the louvers of the louvre, which may cause damage to them. Therefore, the three positioning guide columns 3 are arranged in the cooling triangle 2, the three guide groove wheels 5 are arranged at the corresponding positions outside the first working platform 4, the groove part of the guide groove wheel 5 is clamped on the positioning guide column 3 during use, so that the positioning guide column 3 can provide a guiding action for the movement of the first working platform 4 during the movement of the first working platform 4, so that the first working platform 4 is always located at the center of the cooling triangle 2, and the spray heads 7 on the two waists of the first working platform 4 are always directed to the finned tube bundle 21 at the two waists of the cooling triangle 2.

[0033] The height of the cooling triangle 2 is generally 20-30 meters. If the water pipe for supplying water to the spray head 7 is connected from the ground or the widened platform 1, the soft water pipe is easily bent during the movement of the spray head 7 along with the first working platform 4, which affects the normal water spraying of the spray head 7, and the long water pipe is also easily worn out due to repeated movement. Therefore, the application is provided with a clean water tank 8 on the first working platform 4 for supplying water to the plurality of spray heads 7. Before use, the clean water tank 8 is filled with water. During the movement of the first working platform 4, the clean water tank 8 moves synchronously with the spray head 7. Therefore, the water supply pipe 10 between the water pump 9 in the clean water tank 8 and the spray head 7 is not required to be too long, and the repeated movement is avoided, thereby effectively ensuring the stability of the spray head 7 during use.

[0034] When the equipment maintenance department of the power plant needs to clean the finned tube bundle 21 on the cooling triangle 2 in the air cooling tower, the hoisting equipment is started to drive the first working platform 4 to move vertically from top to bottom in the cooling triangle 2. During the movement, the water pump 9 in the clean water tank 8 pumps water into each spray head 7, so that the plurality of spray heads 7 on both sides of the first working platform 4 uniformly spray water to the finned tube bundles 21 on both sides of the cooling triangle 2. With the movement of the first working platform 4, the plurality of spray heads 7 can also comprehensively clean the finned tube bundles 21 from top to bottom, so that the dirt attached to the finned tube bundles 21 is effectively cleaned, thereby ensuring that the cooling triangle 2 maintains high heat dissipation performance during subsequent use. The plurality of spray heads 7 on each side of the first working platform 4 can cover the entire area in the width direction of the corresponding side of the cooling triangle 2 during work. Therefore, when the plurality of spray heads 7 move from top to bottom once, all the finned tube bundles 21 on the corresponding side can also be correspondingly cleaned once, thereby effectively ensuring that the cleaning process is efficiently performed. In addition, during the entire cleaning process, workers can not enter the inside of the cooling triangle 2, thereby effectively improving the safety during use of the application.

[0035] Further, as shown in Figure 5 and Figure 6 , the water supply pipe 10 includes two branch pipes 101, which are respectively arranged on the upper side of both sides of the first working platform 4. The spray head 7 on each side of the first working platform 4 is connected to the branch pipe 101 at the corresponding position. The mutually close sides of the two branch pipes 101 are connected through a water conveying branch pipe 102. The middle position of the water conveying branch pipe 102 is connected to a water conveying main pipe 103. The end of the water conveying main pipe 103 away from the water conveying branch pipe 102 penetrates through the clean water tank 8 and is connected to the water outlet of the water pump 9 inside the clean water tank 8.

[0036] In the above embodiment, the water pump 9 in the clean water tank 8 can pressurize the clean water in the clean water tank 8 and discharge it from the water outlet when it is working. The water outlet of the water pump 9 is connected to the water supply main pipe 103, and the water supply main pipe 103 is connected to the two water distribution pipes 101 through the water supply branch pipes 102. The multiple spray heads 7 on the two waists of the first working platform 4 are connected to the water distribution pipes 101 on the corresponding sides, respectively. In this way, the water flowing out of the water supply main pipe 103 can be supplied to all the spray heads 7 above the first working platform 4 at the same time, so that the spray heads 7 can continuously spray clean water on the finned tube bundle 21 of the cooling triangle 2 during cleaning, and the clean water can clean the dirt on the surface of the finned tube bundle 21.

[0037] Further, as shown in Figure 4 and Figure 6 , the height of the water outlet end of the spray head 7 towards the finned tube bundle 21 of the cooling triangle 2 in the vertical direction is lower than the height of the connection end of the spray head 7 with the water distribution pipe 101 in the vertical direction.

[0038] In the above embodiment, the spray head 7 of the present application is arranged in the above-mentioned manner, which is inclined from the first working platform 4 to the finned tube bundle 21 on the corresponding side of the cooling triangle 2 on the lateral mounting plate 6. In this way, the impact force of the water flow sprayed by the spray head 7 on the surface of the finned tube bundle 21 is greatly reduced compared to the impact force of the horizontal water spray when it is vertically arranged on the lateral mounting plate 6, thereby reducing the splashing effect of the dirty water generated during the cleaning process to the surrounding area, so as to avoid dirtying the area above the first working platform 4 or the spray head 7 which has been cleaned.

[0039] Further, as shown in Figure 6 , a plurality of supports 12 are arranged on the water distribution pipe 101 in the circumferential direction, and the lower ends of the supports 12 are fixedly installed on the first working platform 4.

[0040] In the above embodiment, the multiple supports 12 arranged at intervals on the water distribution pipe 101 can support and fix the water distribution pipe 101 through the first working platform 4, so as to ensure that the water distribution pipe 101 will not easily shake when the water with pressure flows in it during use.

[0041] Further, as shown in Figure 1 and Figure 2 , the hanging unit 11 includes a door-shaped frame 111 installed on the widened platform 1, and an electric hoist 112 is installed in the middle of the door-shaped frame 111.

[0042] In the above embodiment, a dedicated maintenance window is usually arranged on the widened platform 1 of the cooling tower at a position corresponding to each cooling triangle 2. The door-shaped frame 111 in the hanging unit 11 can be used to span the maintenance window directly above the cooling triangle 2 to be cleaned. The electric hoist 112 on the door-shaped frame 111 is opposite the first working platform 4, and the hook of the electric hoist 112 can drive the first working platform 4 to move up or down. The door-shaped frame 111 and the widened platform 1 can be temporarily fixed by bolts. After cleaning one cooling triangle 2, the first working platform 4 can be lifted out by the electric hoist 112, and the whole unit can be moved to the next cooling triangle 2 to be cleaned, and the corresponding cleaning work can be continued. In this way, a cleaning system does not need to be arranged in each cooling triangle 2, and the production cost can be reduced.

[0043] Further, as shown in Figures 1-5 , a second working platform 13 is arranged in parallel above the first working platform 4. The gap height between the first working platform 4 and the second working platform 13 is not less than the height of the clean water tank 8. The second working platform 13 has the same shape as the first working platform 4. A guide groove wheel 5 is arranged on each of the three corners of the second working platform 13 and is movably connected with the three positioning guide columns 3. The first working platform 4 and the second working platform 13 are connected by a plurality of fixed hangers 14. A water filling pipe 15 is arranged through the second working platform 13. The lower end of the water filling pipe 15 is fixedly inserted into the top of the clean water tank 8, and the internal spaces of the water filling pipe 15 and the clean water tank 8 are connected.

[0044] In the above embodiment, since the first working platform 4 is provided with the clean water tank 8, the water supply branch pipe 102, the water distribution pipe 101, and the water supply main pipe 103, if the worker directly enters the first working platform 4 to add water to the clean water tank 8, the operation space is limited, and the water adding process may be affected by these devices. If the worker accidentally touches these devices, the worker may be injured. Therefore, the second working platform 13 is specially arranged on the first working platform 4. The first working platform 4 is provided with a water filling pipe 15 specially used for adding water to the clean water tank 8. In addition, the second working platform 13 is not provided with other devices. Therefore, the worker can conveniently add water to the clean water tank 8 through the water filling pipe 15 on the second working platform 13. The guide groove wheels 5 arranged on the three corners of the second working platform 13 can cooperate with the guide groove wheels 5 on the three corners of the first working platform 4 to increase the stability of the whole device when moving in the vertical direction.

[0045] Further, as shown in Figure 4 , a protective fence 16 is arranged on the upper side of the second working platform 13 along the circumference thereof. A maintenance opening 17 is arranged on the second working platform 13 on the side of the water filling pipe 15 close to the cooling triangle 2. A cover plate 18 is detachably arranged on the maintenance opening 17.

[0046] In the above embodiment, the manhole 17 on the second working platform 13 facilitates the workers to inspect and repair the equipment such as the pipes or the spray heads 7 on the first working platform 4. The guardrails 16 on the second working platform 13 can improve the safety of the workers standing on the second working platform 13. In actual work, when the inspection and repair is needed in a certain area of the cooling triangle 2 in the vertical direction, the second working platform 13 of the present application can also be used for the workers to stand on, and the workers can be lowered to the designated position by the hoisting unit 11 to carry out the inspection and repair work. In this way, the application range of the present application can be improved.

[0047] Further, as shown in Figure 1 , Figure 2 and Figure 4 , a lifting hole 19 is arranged at the top of each of the three corners of the guardrails 16, and a lifting rope 20 is tied in each of the lifting holes 19, and the end of the lifting rope 20 away from the lifting hole 19 is sleeved on the hook of the electric hoist 112.

[0048] In the above embodiment, the lifting holes 19 on the three corners of the guardrails 16 can provide a lifting point for each of the three lifting ropes 20, and when the hook of the electric hoist 112 is used to drive the second working platform 13 and the first working platform 4 to move by using the three lifting ropes 20, the direction of the force generated by the electric hoist 112 can be made as much as possible to be collinear with the center of the first working platform 4 and the second working platform 13, so that the stability of the first working platform 4 and the second working platform 13 during the movement can be further improved.

[0049] Further, as shown in Figures 4-6 , a lateral mounting plate 6 provided with a plurality of spray heads 7 is also arranged on one side of the first working platform 4 close to the louvers 22 of the cooling triangle 2, and the water outlet ends of the plurality of spray heads 7 on the lateral mounting plate 6 are all directed to the louvers 22 of the cooling triangle 2, and the water inlet ends of the plurality of spray heads 7 are also connected to the water pump 9 in the water tank 8 through a water distribution pipe 101.

[0050] In the above embodiment, the louvers 22 of the cooling triangle 2 at the air inlet are the only way for the natural wind to flow in during use, so some dust and dirt carried by the natural wind will often adhere to the louvers of the louvers 22. In order to ensure smooth air inlet and the aesthetics of the louvers 22 of the cooling triangle 2, it is necessary to clean the louvers 22. The lateral mounting plates 6 added on the first working platform 4 near the louvers 22 of the cooling triangle 2 and the lateral mounting plates 6 on the two waists thereof have the same function of providing a mounting base for the spray heads 7, and the three lateral mounting plates 6 are connected end to end in sequence, which improves the integrity and stability of the three lateral mounting plates 6 on the first working platform 4. A plurality of spray heads 7 are also installed on the lateral mounting plate 6 on the first working platform 4 near the louvers 22. These spray heads 7 are also installed on a dedicated branch pipe 101 together with the plurality of spray heads 7 on one of the waists of the first working platform 4. The water outlet of the water pump 9 connected to the water supply main pipe 103 in the clean water tank 8 can supply a branch to the branch pipe 101 (as shown in Figure 6 ), so that the water pump 9 can supply clean water under pressure to the spray heads 7 on the three edges of the first working platform 4 at the same time when the first working platform 4 moves in the vertical direction, so as to clean the finned tube and the louvers 22 at the same time.

[0051] The implementation principle of the embodiment is that when the cooling triangle 2 of the air cooling tower needs to be cleaned, the access hole 17 at the corresponding position on the widening platform 1 is opened, the door-shaped frame 111 in the hoisting unit 11 is installed, the hoisting rope 20 on the second working platform 13 is hung on the hook of the electric hoist 112 of the door-shaped frame 111, then the worker stands on the second working platform 13 and fills the clean water tank 8 with water through the water filling pipe 15, and then the electric hoist 112 and the water pump 9 are started. The electric hoist 112 slowly lowers the first working platform 4 and the second working platform 13 along the cooling triangle 2. During this process, the plurality of spray heads 7 on the first working platform 4 are started at the same time, and the finned tube bundle 21 and the louvers 22 in the cooling triangle 2 are cleaned at the same time, so that the dirt adhering to the finned tube bundle 21 and the louvers 22 is efficiently cleaned, so as to ensure that the cooling triangle 2 maintains high heat dissipation performance during subsequent use.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features.
