Abstract
Description
Technical Field
[0001] This utility model relates to the field of sulfur dioxide production technology, specifically a drying tower for sulfur dioxide production. Background Technology
[0002] Sulfur dioxide has important uses in the paper industry, including the production of sulfite pulp, the manufacture of various sulfites, bisulfites, and thiosulfates, the synthesis of detergents, rubber accelerators, and other organic compounds, its use in the pharmaceutical industry, its application in bleaching textiles and leather, its use as a fumigation disinfectant in agriculture, and its use as a preservative and disinfectant in the food industry. Currently, gypsum, a mineral resource with abundant reserves, is widely used in the production of high-purity sulfur dioxide. Since gypsum is a compound containing multiple molecules of water of crystallization, moisture is usually produced during its calcination and decomposition process. However, the presence of moisture in sulfur dioxide leads to a low conversion rate. Therefore, effectively drying sulfur dioxide containing moisture to reduce its moisture content and improve its purity is of great importance.
[0003] Existing sulfur dioxide drying equipment dries gas by using built-in desiccant. During use, the surface of the desiccant easily solidifies after absorbing water, preventing the inner layer of desiccant from contacting moisture, thus affecting drying efficiency and practicality. Furthermore, it cannot pulverize the solidified desiccant, wasting raw materials and impacting work efficiency. Utility Model Content

A connecting belt 604 is provided on the rotating shaft 601, and the rotating shaft 601 and the rotating column 605 are connected by the connecting belt 604. The rotating column 605 is rotatably connected to the left side of the tower body 1. A reciprocating screw 606 is fixedly installed on the right side of the rotating column 605. The right side of the reciprocating screw 606 is rotatably connected to the right end of the tower body 1. A screw slider 607 is provided on the reciprocating screw 606. A scraper 608 is fixedly installed at the bottom of the screw slider 607. When the rotating column 605 rotates, the reciprocating screw 606 rotates, and the screw slider 607 slides back and forth. The screw slider 607 drives the scraper 608 to scrape the solidified desiccant to the bottom of the pulverizing cylinder 603.
[0023] The tower body 1 is equipped with an adjustment mechanism 7. The adjustment mechanism 7 includes a sliding plate 701, which is slidably connected to the tower body 1. A groove 702 is provided on the sliding plate 701. A sliding rod 703 is slidably connected inside the groove 702. The top of the sliding rod 703 is hinged to a connecting rod 704. The end of the connecting rod 704 away from the sliding rod 703 is hinged to a fixed seat 705. The bottom of the fixed seat 705 is fixed to the tower door 2. When the fixed seat 705 of the tower door 2 is opened, the connecting rod 704 is driven, and the sliding rod 703 slides in the groove 702, causing the sliding plate 701 to slide outward.
[0024] A fixing plate 4 is fixedly installed on the side of the tower body 1, and a motor 5 is fixedly installed on the top of the fixing plate 4.

Under the action of the connecting belt 604, the rotating column 605 rotates accordingly. The rotating column 605 drives the reciprocating screw 606 to rotate, and the screw slider 607 slides back and forth on the reciprocating screw 606. While the scraper 608 at the bottom of the screw slider 607 slides back and forth, it scrapes the solidified desiccant to both sides of the sliding plate 701. The rotating shaft 601 drives the rotating rod 602 to rotate, and the crushing cylinder 603 rotates... The rod 602 crushes the solidified desiccant. The crushed desiccant will gather in the middle along the inclined surface of the sliding plate 701. When it solidifies and clumps, the scraper 608 will scrape the solidified desiccant to both sides. The sulfur dioxide from the desiccant is sent out from the exhaust pipe 9 above the tower body 1. Repeat the operation. When the drying work is completed, pull the handle 3 to open the tower door 2. The fixed seat 705 drives the connecting rod 704. The connecting rod 704 drives the sliding rod 703 to slide outward in the sliding groove 702. The sliding rod 703 drives the sliding plate 701 to slide outward. When the sliding plate 701 is removed, the desiccant on the sliding plate 701 is replaced.
