Description

Technical Field

[0001] The utility model relates to the technical field of condenser cleaning, in particular to a guide plate device suitable for cleaning condensers with rubber balls. Background Art

[0002] The condenser is an important equipment in power plants and other industrial fields. Its main function is to convert steam into condensed water and discharge non-condensable gases in the steam to maintain the normal operation of the system. During the operation of the condenser, dirt and sediment are easily accumulated on the inner wall of the heat exchange tube, which not only reduces the heat exchange efficiency but also increases energy consumption. In order to keep the condenser clean and operate efficiently, a rubber ball cleaning system is usually used for regular cleaning.

[0003] The traditional rubber ball cleaning system injects a certain number of rubber balls into the condenser. These rubber balls flow with the circulating water in the condenser, collide and rub against the inner wall of the heat exchange tube, thereby removing dirt. The rubber balls are recovered into the rubber ball system through the circulating water. During this period, the dirt attached to the rubber balls is naturally filtered out of the condenser through the filter screen in the condenser. The continuous circulation can achieve the cleaning operation of the inner wall of the condenser heat exchange tube. However, during the cleaning operation, the dirt and impurities attached to the surface of the rubber balls are sometimes difficult to be washed away by the circulating water. However, when these dirt and impurities enter the condenser heat exchange tube for secondary circulation cleaning, they will cause pollution to the inner wall of the condenser heat exchange tube, thereby affecting the cleaning effect and quality.

[0004] Therefore, we have improved the existing condenser rubber ball system to increase the oscillation frequency of the rubber ball during circulation cleaning, so as to help the circulating water to wash away the dirt on the surface of the rubber ball, thereby accelerating the natural discharge of dirt in the condenser.

[0007] A fixing plate is fixedly mounted on the fixing surface of the mounting plate, and a plurality of rows of bolt holes I are opened on the fixing plate. The fixing plate is screwed to the inner wall of the condenser through bolt fasteners.

[0008] Several rows of guide plate groups are arranged on the mounting surface of the mounting plate, and each row of guide plate groups is composed of several columns of guide plate groups. Each column of the guide plate groups includes a connecting rod and several guide rods. One end of the connecting rod is vertically fixed on the mounting surface of the mounting plate.

The installation direction of the guide rod is parallel to the moving direction of the circulating water and the rubber ball in the condenser, so that the rubber ball can collide with the connecting rod when moving in the condenser.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are:

[0016] (1) The guide plate group can complicate the flow path of the rubber ball in the condenser. The guide rods in two adjacent rows of guide plate groups are staggered, which increases the number of collisions between the rubber ball and the guide plate, thereby facilitating the separation of impurities and dirt on the rubber ball's surface during the collision, so that this part of the dirt can be naturally discharged outside the condenser, thereby improving the rubber ball's cleaning effect on the inner wall of the heat exchange tube.

[0018] (3) Through the bolt hole I on the fixing plate, the bolt fasteners can be firmly installed on the inner wall of the condenser. At the same time, the upper and lower symmetrical arrangement of the fixing plate can enhance the installation stability of the mounting plate. In addition, the external thread on the connecting rod and the auxiliary connecting plate make it easy to install and disassemble the guide plate group, which is convenient for maintenance and replacement.

[0022] The following further describes the specific technical solutions of the present invention with reference to the accompanying drawings, so as to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to their rights.

[0023] Example 1, with reference to Figure 1-2 A guide plate device suitable for cleaning condensers with rubber balls. The core principle is to complicate the flow path of the rubber balls in the condenser 1 and increase the number of collisions between the rubber balls 2 and the guide rods 3, thereby improving the cleaning effect of the rubber balls 2 on the inner wall of the heat exchange tubes;

[0024] Specifically, the device is arranged on the inner wall of the condenser 1, between the filter screen and the heat exchange tube of the condenser 1. The main components of the device include a mounting plate 4, a fixing plate 5, a connecting rod 6 and a guide rod 3. The mounting plate 4 serves as the supporting structure of the entire device. One side of the mounting plate 4 is opposite to the inner wall of the condenser 1 and serves as the fixing surface of the mounting plate 4 for fixing the fixing plate 5. The other side serves as the mounting surface of the mounting plate 4 for installing the guide plate group.

[0025] The fixing plate 5 is used to securely mount the device on the inner wall of the condenser 1. The fixing plate 5 is provided with a plurality of rows of bolt holes I7, which are screwed to the inner wall of the condenser 1 through bolt fasteners. At the same time, the fixing plate 5 is also provided with bolt holes II8 for the connecting rod 6 to pass through. The outer peripheral surface of the end of the connecting rod 6 is provided with an external thread that is threadedly connected to the bolt hole II8. This design enables the connecting rod 6 to be stably fixed to the fixing plate 5.

[0026] In order to improve the installation stability of the connecting rod 6, an auxiliary connecting plate 10 is fixed to the outer peripheral surface of the thread termination line of the external thread of the connecting rod 6. Bolt holes III 9 are opened on the auxiliary connecting plate 10 and the fixing plate 5 to achieve relative fixation by bolt fasteners. This double fixing method ensures the stability of the connecting rod 6.

[0027] On the mounting surface of the mounting plate 4, there are several rows of guide plate groups. Each row of guide plate groups is composed of several columns of guide plate groups. The guide plate groups are arranged equidistantly, and the installation gap between two adjacent groups is the same. Each guide plate group contains several columns of guide rods 3, and the installation gap between each column is also the same. This equidistant and uniform arrangement ensures the maximum collision coverage range.

[0028] The guide rods 3 in two adjacent rows of guide plate groups are staggered on the connecting rods 6. This design increases the number of collisions between the rubber ball 2 and the guide rods 3 during the flow process. The guide rods 3 are formed into roughly cylindrical rods. Their design purpose is to naturally remove impurities and dirt on the surface of the rubber ball 2 through the shock force during the collision with the rubber ball 2. The installation direction of the guide rods 3 is parallel to the direction of movement of the circulating water and the rubber ball 2 in the condenser 1, so that the rubber ball 2 can collide with the connecting rod 6 and the guide rods 3 when moving in the condenser 1.

[0029] When the rubber ball 2 circulates in the condenser 1, it will be guided by the guide plate group, thereby complicating its flow path. The rubber ball 2 will continuously collide with the guide rod 3 and the connecting rod 6 during the flow process. The shock force generated by this collision will cause the impurities and dirt on the surface of the rubber ball 2 to be separated by shock. As the rubber ball 2 continues to flow, the separated dirt will be naturally discharged to the outside of the condenser 1, thereby achieving effective cleaning of the inner wall of the heat exchange tube.
