Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for shell-and-tube heat exchangers, specifically to the cleaning and descaling structure for shell-and-tube heat exchangers. Background Technology

[0002] Shell-and-tube heat exchangers (also known as tube-and-shell heat exchangers) are the most widely used indirect heat exchangers in production. Their cleaning and descaling structures are crucial for maintaining the performance of the heat exchanger and extending its service life.

[0003] Ultrasonic descaling utilizes the vibration and cavitation effects of ultrasound to remove dirt. Ultrasound is a high-frequency vibration wave; when it acts on the surface of dirt, it generates strong impact and vibration, thereby breaking down the molecular structure of the dirt and causing it to detach from the surface. Ultrasonic descaling has advantages such as high efficiency, environmental friendliness, and safety, and it will not cause corrosion or damage to equipment.

[0004] However, when existing ultrasonic vibration devices vibrate the inner wall surface of shell-and-tube heat exchangers, the connecting wires of the ultrasonic vibration devices become tangled in the movement, making it troublesome to tidy up the wires and requiring a lot of time to handle. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning and descaling structure for shell-and-tube heat exchangers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning and descaling structure for a shell-and-tube heat exchanger, including an acoustic descaling device and a connecting shell. The shell-and-tube heat exchanger is installed at the front end of the acoustic descaling device, and the connecting shell is installed at the front end of the acoustic descaling device. A temperature sensor is installed on the inner wall surface of the shell-and-tube heat exchanger. The temperature of the temperature sensor and the temperature of the heat exchanger surface can form a temperature difference, which facilitates the determination of whether there is fouling inside the shell-and-tube heat exchanger and the amount of fouling.

[0007] The acoustic descaling device includes a computing host, connecting wires, a support frame, and an acoustic generator. The acoustic generator is installed at the front end of the connecting wires, the connecting wires are installed on the front of the computing host, and the computing host is installed at the rear end of the support frame.

[0009] Preferably, the connecting frame is slidably connected to the upper end of the support frame, and the steel bracket is slidably connected to the upper surface of the support frame. The connecting frame and the steel bracket slide on the surface of the support frame, thereby allowing the position of the connecting frame and the steel bracket to be adjusted, and thus the position of the connecting wire to be adjusted.

[0010] Preferably, the sliding connecting block is threaded to the middle position of the connecting wire, the steel bracket is threaded to the middle position of the connecting wire, and a threaded rod is inserted at the connection between the sliding connecting block and the steel bracket, so as to fix the steel brackets together by threads, thereby preliminarily determining the position of the connecting wire.

[0012] Preferably, there are two wire carrier blocks, which are distributed left and right. The wire carrier blocks are movably connected to the upper end of the connecting wire. The wire carrier blocks can determine the position of the connecting wire, making it convenient to adjust the position of the connecting wire.

[0013] Preferably, the acoustic generator is inserted into the upper end of the shell-and-tube heat exchanger. There are four acoustic generators in total. Two sets of acoustic generators are distributed left and right, and two acoustic generators on the same side are distributed vertically. The upper and lower acoustic generators on the same side are at a 90-degree angle. The acoustic generator connector at the lower end is connected to the inside of the outer shell, which can perform descaling operations on the scale connecting the outer shell and the inside of the shell-and-tube heat exchanger.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The cleaning and descaling structure of this shell-and-tube heat exchanger includes an electrical wire support block, a steel bracket, and a sliding connection block. The electrical wire support block supports the electrical wires, while the steel bracket and sliding connection block limit the position of the electrical wires, thus fixing their position and facilitating wire management. This reduces the time spent on wire management, shortens the adjustment time of the acoustic generator, and increases the service life of the device.

[0015] 2. The cleaning and descaling structure of this shell-and-tube heat exchanger is equipped with a steel bracket, a sliding connecting block, and a support frame. The rear end of the sliding connecting block is equipped with a locking bolt, which can determine the position of the steel bracket and the sliding connecting block.

The connecting slider 133 is slidably connected to the surface of the computing processor 11. The connecting slider 133 can move left and right inside the fixed base 131, thereby adjusting the position of the connecting slider 133. The connecting slider 133 slides on the lower surface of the computing processor 11, thereby adjusting the position of the support frame body 132. The support frame body 132 is threadedly connected to the front end of the connecting slider 133. The sliding connecting block 135 is threadedly connected to the upper section of the support frame body 132 and threadedly connected to the middle position of the connecting wire 12. The steel bracket 134 is threadedly connected to the middle position of the connecting wire 12. The sliding connecting block 135 and the steel bracket 134 are connected... A threaded rod is inserted at the joint, which can fix the steel bracket 134 with threads, thereby initially determining the position of the connecting wire 12. The steel bracket 134 is slidably connected to the upper section of the support frame 132. The wire carrying block 136 is inserted into the front section inside the connecting frame 137. The connecting frame 137 is slidably connected to the upper end of the support frame 132. The steel bracket 134 is slidably connected to the upper surface of the support frame 132. The connecting frame 137 and the steel bracket 134 slide on the surface of the support frame 132, thereby adjusting the position of the connecting frame 137 and the steel bracket 134, and thus adjusting the position of the connecting wire 12. The wire carrying block 136 is movably connected to the top surface of the steel bracket 134. There are two wire carrying blocks 136, which are distributed left and right. The wire carrying blocks 136 are movably connected to the upper end of the connecting wire 12. The wire carrying blocks 136 can determine the position of the connecting wire 12, which is convenient for adjusting the position of the connecting wire 12.

[0022] In use, push the support frame 132 to move backward, so that the back of the support frame 132 and the front end of the connecting slider 133 are movably connected. Then rotate the nut, which can fix the support frame 132 and the connecting slider 133 with threads, thereby determining the position of the support frame 132.

[0023] Pushing the steel bracket 134 and the sliding connecting block 135 downwards allows the steel bracket 134 and the sliding connecting block 135 to slide on the surface of the support frame 132, thereby adjusting the position of the steel bracket 134 and the sliding connecting block 135.

[0024] Push the connecting wire 12 downward so that it is positioned between the steel bracket 134 and the sliding connecting block 135. Then push the threaded rod so that it is inserted into the connection between the steel bracket 134, the sliding connecting block 135 and the connecting wire 12.
