Description

Technical Field

[0001] The utility model relates to a pressure roller transmission mechanism, in particular to a sulfur dioxide storage device, belonging to the technical field of sulfur dioxide storage. Background Art

[0002] Sulfur dioxide (chemical formula: SO2) is the most common sulfur oxide. A colorless gas with a strong, pungent odor, it is a major atmospheric pollutant and is produced in many industrial processes. Sulfur dioxide has industrial value in areas such as corrosion prevention and bleaching, and manufacturers also produce and process it. Liquid sulfur dioxide is relatively stable and inactive. To better store and use it, gaseous sulfur dioxide is converted into liquid form.

[0003] In the prior art, the utility model with application number 202222968570.2 discloses a liquid sulfur dioxide storage device, in which air is sent into the cavity inside the liquid partition plate through an air-cooling component for flow, so that the storage device can evenly cool down the middle of the stored liquid sulfur dioxide. Combined with the light shield and rubber insulation pad on the outside of the box, the storage device can maintain the internal storage cavity at a low temperature suitable for storing liquid sulfur dioxide, which is beneficial to maintaining the quality of the liquid sulfur dioxide stored in the storage device.

[0004] Similar to the above application, there are still some deficiencies:

[0005] Although sending air into the inner cavity of the baffle plate through the air cooling component to exchange heat with the sulfur dioxide has a certain cooling effect, the special square shape and complex structure are not conducive to the storage of sulfur dioxide. Many welding parts are easily corroded, resulting in sulfur dioxide leakage. In addition, the cooling air temperature increases as the flow path increases, resulting in a higher temperature of sulfur dioxide near the cold air outlet and a large temperature difference between the sulfur dioxide on the left and right. In addition, the outer side of the baffle plate is kept inside for a long time, which is not conducive to cleaning, affecting the heat exchange efficiency in the later stage and failing to quickly reduce the internal sulfur dioxide to a low temperature state.

[0006] Therefore, a sulfur dioxide storage device is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the present invention is to provide a sulfur dioxide storage device to solve the problems raised in the above background technology.

A sealing plate 104 is installed at the bottom of the heat pipe 101. Heat conducting rods 105 are evenly provided at the bottom of the sealing plate 104, and the heat conducting rods 105 extend to the bottom of the tank body 1.

[0041] like Figure 1-Figure 3 As shown, as a preferred embodiment, based on the above method, the heat dissipation structure 200 further includes a heat dissipation plate 201 and a protective net 202. The heat dissipation plates 201 are evenly installed on both sides of the cooling box 106, and a protective net 202 is installed on the outside of the heat dissipation plate 201.

[0042] The heat of the coolant inside the cooling box 106 is evacuated to the outside, and at the same time the protective net 202 protects the heat sink 201 to reduce the adhesion of dust to the outside of the heat sink 201 and the influence of heat dissipation.

[0047] Example 3

[0048] The solutions in Example 1 and Example 2 are further introduced below in conjunction with specific working methods, as described below:

[0049] The sulfur dioxide inside the tank body 1 is cooled by an external refrigeration device and stored in the tank body 1 in liquid form. In order to keep the sulfur dioxide liquid at a low temperature, the pump body 107 is first started to suck the coolant in the cooling box 106 into the liquid inlet pipe 108, and then the coolant is cooled by the refrigeration component 109 and rises rapidly to the top through the heat exchange tube 110 to enter the spiral tube 111, so that the coolant in the spiral tube 111 flows downward from top to bottom and in a spiral path, so that the heat of the coolant is transferred to the sulfur dioxide through the heat pipe 101 and the heat conducting plate 102, and heat is exchanged with the sulfur dioxide, thereby reducing the temperature of the sulfur dioxide in the tank body 1 from top to bottom. At the same time, the coolant inside the cooling box 106 at the bottom exchanges heat with the heat conducting rod 105, transferring the heat of the coolant from bottom to top to the heat conducting rod 105. At the hot rod 105 and the sealing disk 104, the heat pipe 101 contacts the sulfur dioxide from bottom to top for heat exchange, thereby reducing the temperature of the sulfur dioxide in the upper and lower parts of the tank body 1. After multiple heat exchanges, the temperature of the coolant increases and is evacuated outward from the outer heat sink 201. The protective net 202 protects the heat sink 201 to reduce the adhesion of dust and impurities between the heat sinks 201. After the sulfur dioxide is discharged from the inside of the tank body 1, the motor 301 is started to drive the scraper 302 to rotate. The scraper 302 scrapes off the residual impurities inside the tank body 1, and the card slot 304 inside the scraper 302 is attached to the outside of the heat sink 102, the heat pipe 101 and the block 103 to clean the outside of the heat sink 102, the heat pipe 101 and the block 103 and scrape off the residue on the outside.
