Description

Technical Field

[0001] This invention belongs to the field of condenser cleaning technology, and relates to a ball loading chamber with a simple ball release function and its working method. Background Technology

[0002] With the increasing size of coal-fired power plants and the in-depth promotion and implementation of energy-saving and emission-reduction technologies, the energy conservation of current thermal power units needs to be further deepened. After the turbine body has been modified for flow path, it is difficult to find new energy-saving measures. The energy-saving potential of the turbine cold end system is receiving more and more attention. Therefore, it is necessary to tap the energy-saving potential from the auxiliary equipment. Improving the performance of the condenser and reducing the back pressure of the unit is a very effective energy-saving measure.

[0003] For water-cooled steam turbine generator sets, factors such as cooling water quality make it difficult to maintain a good level of cleanliness in the condenser. This leads to increased scaling within the condenser tube bundle, resulting in decreased heat transfer performance, increased turbine steam consumption, and impact on the unit's back pressure. To maintain a high condenser cleanliness coefficient, it is necessary to improve the effectiveness of the sprue cleaning process. For example... Figure 1 As shown, the condensate ball cleaning system mainly consists of a ball collection net, a ball pump, a ball loading chamber, and system valves and pipelines. The ball loading chamber's primary function is to store the condensate balls recovered by the condenser ball pump. The loading chamber is required to have functions for loading, unloading, storing, and transporting condensate balls. After system operation, the condensate balls need to be removed to calculate the recovery rate. Currently, removing the condensate balls from the loading chamber requires opening the chamber and manual removal. This presents problems such as high labor intensity, complex operation, and the risk of personnel injury. Summary of the Invention

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A ball-loading chamber with a simple ball-releasing function includes an outer shell assembly, and a water inlet pipe is connected to the side wall of the outer shell assembly;

[0007] The outer shell assembly is provided with a mesh core, the upper port of which is located below the water inlet pipe, and the lower port of which is connected to the ball filling chamber bottom plate. A four-way switching valve is located below the ball filling chamber bottom plate.

[0008] The ball loading chamber bottom plate has ports A and B; the upper end of port A is connected to the lower end of the mesh core, and the lower end of port A is connected to port F of the four-way switching valve; port B is connected to one end of a bend, and the other end of the bend is connected to port E of the four-way switching valve; port C of the four-way switching valve is connected to one end of the water outlet pipe, and port D of the four-way switching valve is connected to a ball release butterfly valve; a valve core is installed in the four-way switching valve.

[0009] The water outlet pipe extends out of the outer casing assembly.

[0016] Preferably, each port of the four-way switching valve is connected to the connected assembly via a flange.

[0017] Preferably, the lower end of the outer casing assembly is provided with a ball-filling chamber base.

[0018] A method for operating a ball-loading chamber with a simple ball-releasing function as described in any one of the above claims, wherein when the ball-loading chamber throws a ball, the valve core blocks port E, and the rubber ball is thrown out through ports A and C;

[0019] When the ball loading chamber receives the ball, the valve core blocks port A, and the rubber ball is left in the net core;

[0020] When the ball filling chamber discharges the rubber balls, the valve core blocks port C, opens the ball discharge butterfly valve, and the rubber balls are released.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention discloses a ball-loading chamber with a simple ball-releasing function and its operating method. During operation of the ball cleaning system, the ball-loading and ball-collecting functions of the chamber can be realized by controlling a four-way switching valve.

[0033] See Figure 2 This invention proposes a ball-loading chamber with a simple ball-releasing function. The ball-loading chamber consists of an outer shell assembly 3, a mesh core 7, a four-way switching valve 10, and a bent pipe.

[0034] The outer casing assembly 3 consists of an upper flange 4, an inlet pipe 5, a casing 6, a ball-filling chamber base plate 8, an outlet pipe 14, and a ball-filling chamber base 15. These components are welded to the casing 6. Specifically, the casing 6 has a barrel-shaped structure. The upper end of the casing 6 is connected to the upper flange 4, which in turn connects to the upper cover 1 of the ball-filling chamber. An observation window 2 is embedded in the center of the upper cover 1. The lower end of the casing 6 is connected to the ball-filling chamber base 15, which provides support for the casing 6.

[0035] The mesh core 7, the ball-loading chamber bottom plate 8, the elbow 9, the four-way switching valve 10, and the outlet pipe 14 are all located within the housing 6.

[0036] A water inlet pipe 5 is connected to the side wall of the shell 6. The mesh core 7 is an inverted frustum structure with open upper and lower surfaces. The mesh core 7 and the shell 6 are coaxially arranged. The diameter of the upper surface of the mesh core 7 is larger than that of the lower surface. The upper surface of the mesh core 7 is lower than the height of the water inlet pipe 5. The upper end of the mesh core 7 is welded to the shell 6 along its axial direction, and the lower end is welded to the A-port of the ball filling chamber bottom plate 8. Holes 24 are arranged on the side wall of the mesh core 7. Preferably, the holes 24 are arranged in an array along the length and circumferential direction of the side wall.

[0037] The ball loading chamber bottom plate 8 is a plate-shaped structure set in the shell 6. Its side is fixedly connected to the inner wall of the shell 6. The ball loading chamber bottom plate 8 has an opening A at its center and an opening B on one side of the opening A. Both opening A and opening B are through holes.

[0038] A bend 9, a four-way switching valve 10, and a water outlet pipe 14 are installed at the lower part of the ball filling chamber bottom plate 8. The four-way switching valve 10 consists of a valve body 11 and a valve core 12. Four ports, C, D, E, and F, are arranged sequentially on the valve body 11, with an included angle of 90° between the axes of two adjacent ports. The four ports are connected to the ball filling chamber bottom plate 8, the water outlet pipe 14, the ball release butterfly valve 13, and the bend 9 by flanges, respectively. The valve core 12 is installed at the center of the valve body 11 and is surrounded by the four ports. The valve core 12 has three through holes, and the valve core 12 is a hollow structure.

One end of the elbow 9 is connected to the B port of the ball filling chamber bottom plate 8 via a flange, and the other end is connected to the E port flange of the four-way switching valve 10. The F port is above the D port.

[0040] The working method of the device of the present invention is as follows:

[0041] During operation, the rubber balls enter the mesh core 7 through the water inlet pipe 5 with the water flow, at which time the ball release butterfly valve 13 is closed. When throwing balls in the ball loading chamber, valve core 12 blocks port E of the four-way switching valve 10, and the rubber balls are thrown out. When collecting balls in the ball loading chamber, valve core 12 blocks port A of the four-way switching valve 10, and the rubber balls are left inside the mesh core 7, while the water flows out through the opening and bend of the mesh core 7 via port B. When the system operation ends and it is necessary to discharge the rubber balls to count the number and calculate the ball collection rate, valve core 12 blocks port C of the four-way switching valve 10 and simultaneously opens the ball release butterfly valve 13, and the rubber balls are released. This realizes the simple ball release function in the ball loading chamber, eliminating the need for manual ball retrieval.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
