[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides a technical solution: Figure 1 - Figure 5The shown device is a freezing purification device for an organic amine desulfurization solution in a thermal power plant, comprising a box body 1, a transmission pipe 12 being fixedly connected to the inside of the box body 1, a sliding groove 2 being provided on one side of the box body 1 near the transmission pipe 12, two groups of sliding grooves 2 being symmetrically arranged, a freezing plate 3 being slidingly connected to the inside of the sliding groove 2, a positioning plate 4 being fixedly connected to the inside of the box body 1 near the sliding groove 2, a mounting groove 5 being provided on the end of the positioning plate 4 away from the box body 1, a scraper 6 being slidingly connected to the inside of the mounting groove 5, and the end of the scraper 6 away from the positioning plate 4 being in contact with the bottom of the freezing plate 3, a frost removal groove 8 being provided on the side of the box body 1 near the freezing plate 3, a collecting plate 7 being fixedly connected to the inside of the box body 1 near the frost removal groove 8, and the collecting plate 7 being arranged in an "L" shape.

[0020] During operation, liquid is transmitted through the transmission pipe 12. At this time, the transmission pipe 12 can be cooled by the freezing plate 3. Frost will adhere to the surface of the freezing plate 3 after it has been used for a period of time. At this time, the freezing plate 3 is pulled out along the sliding groove 2. When the freezing plate 3 is pulled out, it will slide along the side of the scraper 6 installed in the mounting groove 5 inside the positioning plate 4. In this way, the frost will slide along the side of the scraper 6 and fall on the surface of the collection plate 7. The frost is transmitted out along the frost discharge groove 8, which achieves the effect of quickly cleaning the frost on the surface of the freezing plate 3, and solves the problem of cooling the liquid inside the pipeline by the cooling plate in the past. However, this method will form frost on the surface of the cooling plate under long-term use, causing the temperature inside the cooling box to be uncontrollable, thereby improving the controllability of the temperature.

[0021] See also Figure 4 and Figure 5 In the figure, the inside of the box body 1 is fixedly connected to a slide rail 11, and the slide rail 11 is arranged on both sides of the freezing plate 3. There are two groups of slide rails 11 arranged symmetrically. A mounting hole 9 is opened on one side of the box body 1. The mounting hole 9 is opened on one side of the box body 1 near the scraper 6. A handle 10 is fixedly connected to one end of the scraper 6, and the handle 10 abuts against the side of the box body 1 near the mounting hole 9.

[0022] During operation, when the freezing plate 3 is pulled, the freezing plate 3 slides inside the box body 1 by means of the slide rail 11, thus ensuring the smooth movement of the freezing plate 3. The scraper 6 will wear out after long-term use, so the handle 10 can be used to pull it, thereby driving the scraper 6 to slide out along the mounting groove 5 and the mounting hole 9, so that the scraper 6 can be removed from the inside of the box body 1, thereby solving the problem of quickly replacing the scraper 6 and improving the convenience of replacing the scraper 6.

[0023] See also Figure 1 and Figure 4 In the figure, the freezing plate 3 is fixedly connected to the side away from the box body 1 with a handle 13, and a collection component is provided at the bottom of the box body 1. The collection component includes a limiting rail 15. There are two groups of limiting rails 15 fixedly connected to the bottom of the box body 1, and the limiting rails 15 are slidably connected to the collection box 14 on the opposite side.

[0024] During operation, the freezing plate 3 can be more conveniently pulled out along the sliding groove 2 through the handle 13. Before pulling out the freezing plate 3, the collection box 14 is first pulled out along the limit rails 15, and the frost cleaned on the surface of the freezing plate 3 will fall into the collection box 14 for collection, avoiding affecting the surrounding environment, thereby achieving the effect of collecting the frost cleaned on the freezing plate 3.

[0025] Working principle: liquid is transmitted through the transmission pipe 12, and the transmission pipe 12 can be cooled through the freezing plate 3. After the freezing plate 3 has been used for a period of time, frost will adhere to the surface. At this time, the freezing plate 3 is pulled out along the sliding groove 2. When the freezing plate 3 is pulled out, it will slide along the side of the scraper 6 installed in the installation groove 5 inside the positioning plate 4, so that the frost will slide along the side of the scraper 6 and fall on the surface of the collection plate 7. The frost is transmitted out along the frost discharge groove 8, thus achieving the effect of quickly cleaning the frost on the surface of the freezing plate 3, solving the problem of cooling the liquid inside the pipeline through the cooling plate in the past, but this method will form frost on the surface of the cooling plate under long-term use, causing the temperature inside the cooling box to be uncontrollable, and improving the controllability of the temperature. When the freezing plate 3 is pulled, The freezing plate 3 slides inside the box body 1 by means of the slide rail 11, thus ensuring the smooth movement of the freezing plate 3. The scraper 6 will wear out after long-term use, so the handle 10 can be used to pull the scraper 6 to slide out along the mounting groove 5 and the mounting hole 9, so that the scraper 6 can be removed from the inside of the box body 1, thereby solving the problem of quickly replacing the scraper 6 and improving the convenience of replacing the scraper 6. The freezing plate 3 can be more conveniently pulled out along the sliding groove 2 through the handle 13. Before pulling out the freezing plate 3, the collection box 14 is first pulled out between the limit rails 15, and the frost cleaned on the surface of the freezing plate 3 will fall into the collection box 14 for collection, avoiding affecting the surrounding environment, thereby achieving the effect of collecting the frost cleaned on the freezing plate 3.
