Opening grooves are formed on both sides of the heat exchange box, and sliding plates are slidably connected within these grooves. A mounting plate with vent holes is fixedly connected to the opposite side of each sliding plate. Several heat exchange plates arranged in an array are arranged in the middle of the mounting plates. Mounting holes are formed through the four corners of each heat exchange plate. A bracket with through holes and a limiting plate are fixedly connected to the mounting plates on both sides of the heat exchange plates. Sliding grooves are formed on the inner walls of both sides of the brackets. Magnetic rods with pull plates are inserted into both the brackets and the mounting holes. Sliding rods are fixedly connected to both sides of the magnetic rods, with the opposite side of the sliding rods slidably connected within the sliding grooves. Springs are fixedly connected to the inner walls of both the sliding rods and the brackets on the other side. Magnetic blocks are fixedly connected to the inner walls of the limiting plates and the corresponding magnetic rods, and the magnetic blocks and magnetic rods are magnetically connected.

[0022] See Figure 1-5 As shown in the figure, an embodiment of the present invention provides a plate heat exchanger for formaldehyde production, including a heat exchange box 1 with an openable cover at the top, support plates 2 fixedly connected to both sides of the heat exchange box 1, and gas pipes 3 connected to the heat exchange box 1 fixedly connected to both sides of the support plates 2.

[0023] In use, formaldehyde is introduced into the heat exchange box 1 through the side air pipe 3 and the support plate 2, where it is processed. After processing, it is discharged into the external equipment for storage and use through the air pipe 3 on the other side support plate 2.

[0024] Both sides of the heat exchange box 1 have open sliding grooves 4, and sliding plates 5 are slidably connected within the open sliding grooves 4. Each sliding plate 5 has a mounting plate 6 with vent holes fixedly connected to its opposite side. Several heat exchange plates 8 arranged in an array are arranged in the middle of the mounting plates 6. Mounting holes 9 are drilled through the four corners of each heat exchange plate 8. Supports 10 with through holes and limiting plates 15 are fixedly connected to the mounting plates 6 on both sides of the heat exchange plate 8, respectively. Sliding grooves 11 are formed on the inner walls of both sides of the support 10. Magnetic rods 12 with pull plates are inserted into both the support 10 and the mounting holes 9. 2. Slide rods 13 are fixedly connected to both sides. The slide rods 13 are slidably connected to the sliding groove 11 on the opposite side. Springs 14 are fixedly connected to both the slide rods 13 and the inner wall of the bracket 10 on the other side. Magnetic blocks 16 are fixedly connected to the inner walls of the limiting plate 15 and the magnetic rod 12. Magnetic blocks 16 and magnetic rods 12 are magnetically connected. Sealing rings 7 are fixedly connected to the opposite side of the mounting plate 6. Sealing rings 7 are tightly connected to the inner walls of both sides of the heat exchange box 1. Corrugated patterns are provided on the heat exchange plates 8.

[0025] In use, open the top cover of the heat exchange box 1, and insert the heat exchange plate 8 between the bracket 10 and the limiting plate 15 on the mounting plate 6. At this time, pull the magnetic rod 12 by pulling the pull plate. The magnetic rod 12 moves inside the bracket 10 under force. At the same time, when the magnetic rod 12 moves, it drives the slide rod 13 to slide in the sliding groove 11. When the slide rod 13 moves, it will compress the spring 14. When the pull plate is released, the magnetic rod 12 will pass through the mounting hole 9 and be magnetically connected to the magnetic block 16 under the elastic action of the spring 14 and the sliding limiting action of the sliding groove 11 and the slide rod 13 to limit the heat exchange plate 8. At this time, the mounting plate 6 drives the sliding plate 5 to slide and connect inside the sliding groove 4. When the fluid enters the heat exchange box 1, the sealing ring 7 on the mounting plate 6 increases the overall sealing performance to prevent leakage. At the same time, the heat exchange plate 8 is treated with formaldehyde, which facilitates the replacement and use of the whole system.

[0026] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention.
