Description

Technical Field

[0001] This utility model belongs to the field of desulfurization equipment technology, specifically relating to a dual-tower dual-circulation desulfurization system. Background Technology

[0002] Flue gas desulfurization refers to the removal of sulfur oxides from flue gas or other industrial waste gases. Desulfurization methods include dry desulfurization, spray desulfurization, coal ash desulfurization, and wet desulfurization. Spray towers are the most commonly used type of tower in wet desulfurization systems. A spray tower consists of several layers of nozzles arranged inside its absorption tower. The desulfurizing agent is sprayed through the nozzles to form a liquid mist. The mass transfer process is completed through sufficient contact between the liquid mist and the flue gas, thus purifying the flue gas.

[0003] Existing desulfurization equipment has a relatively simple structure. During desulfurization, the desulfurizing agent cannot fully and effectively contact the flue gas, resulting in the inability to remove sulfides in the flue gas. Multiple desulfurization cycles are required to meet the standards, which also affects the overall desulfurization effect and rate. Furthermore, it is inconvenient to disassemble and install the filter screen of the desulfurization equipment, affecting the later replacement of the filter screen. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a dual-tower dual-circulation desulfurization system to solve the problems mentioned in the background art.

An installation groove is opened in the exhaust pipe, and a metal plate is connected to the front end of the exhaust pipe. A filter screen is placed in the installation groove, and a docking groove is opened in the metal plate.

[0007] Furthermore, an air intake pipe is connected between the first desulfurization tower and the second desulfurization tower, and the air intake pipe is fixedly connected to the first desulfurization tower and the second desulfurization tower.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 5 As shown, this embodiment provides a dual-tower dual-circulation desulfurization system, including a device body 1. The device body 1 contains a desulfurization tower 1 2 and a desulfurization tower 2 3. A connecting pipe 8 is connected to the left side of the desulfurization tower 1 2 and a flue gas inlet pipe 6 is connected to the front end of the desulfurization tower 1 2. One end of the connecting pipe 8 is connected to a pump body 7 and a control valve 9 is installed above the connecting pipe 8. A cover plate 11 is installed above the desulfurization tower 2 3. A motor 12 is installed above the cover plate 11. A connecting rod 13 is connected below the motor 12. The connecting rod 13 is located inside the desulfurization tower 2 3 and a fixing ring 14 is installed on the connecting rod 13. A flue gas exhaust pipe 16 is connected to the front end of the desulfurization tower 2 3. An installation groove 17 is opened in the flue gas exhaust pipe 16 and a metal plate 19 is connected to the front end of the flue gas exhaust pipe 16. A filter screen 18 is placed in the installation groove 17 and a docking groove 20 is opened in the metal plate 19.

[0025] Preferably, a gas inlet pipe 10 is connected between desulfurization tower 2 and desulfurization tower 3. The gas inlet pipe 10 is fixedly connected to desulfurization tower 2 and desulfurization tower 3. By setting the gas inlet pipe 10, the gas in desulfurization tower 2 can be diverted, making it convenient for the gas to enter desulfurization tower 3 for secondary treatment. A spray port 4 and an inspection door 5 are set above desulfurization tower 2. The inspection door 5 is located below the spray port 4. The spray port 4 facilitates the treatment of the gas entering desulfurization tower 2. The inspection door 5 facilitates the maintenance and repair of the interior of desulfurization tower 2 by the staff, increasing the practicality and convenience of the device.

[0026] Preferably, multiple sets of fixing rings 14 are provided, and the fixing rings 14 are fixedly connected to the connecting rods 13. Fan blades 15 are fixedly installed on the outer wall of the fixing rings 14. Multiple sets of fan blades 15 are provided. By setting the fan blades 15, the gas that needs to be desulfurized entering the desulfurization tower 2 3 can be dispersed, so that the flue gas and the added desulfurizing agent can be fully and evenly mixed and contacted, thereby improving the desulfurization efficiency. The front end of the filter screen 18 is provided with a pressure plate 21. A strong magnet 22 is connected to the inner wall of the pressure plate 21. The strong magnet 22 is magnetically attracted in the docking groove 20, which can limit and fix the filter screen 18, ensuring the safety of the filter screen 18 during use and avoiding the trouble of disassembling the pressure plate 21 later. A handle 23 is installed on the outer wall of the pressure plate 21. Two sets of handles 23 are symmetrically provided and the handles 23 are fixedly connected to the pressure plate 21. By setting the handles 23, it is convenient for users to control and use the pressure plate 21, which increases the practicality of the device and provides convenience for users.

[0027] The working principle and process of this utility model are as follows: During use, the gas to be desulfurized is introduced into desulfurization tower 2 through the inlet pipe 6. The gas disperses and floats within desulfurization tower 2. The operator opens the spray nozzle 4 and controls the external spray equipment to desulfurize the gas entering desulfurization tower 2 through the spray nozzle 4. After treatment, the gas re-enters desulfurization tower 3 through the priming pipe 10. Then, the motor 12 is controlled to run, rotating the connecting rod 13. The rotation of the connecting rod 13 drives the fixed ring 14 to rotate, which in turn drives the fan blades 15 to disperse the gas entering the device. During this dispersion process, the gas is fully and evenly mixed and contacted with the added desulfurizing agent. The desulfurized gas then passes through the filter screen 1 of the exhaust pipe 16. After filtration, the gas entering the device is fully and evenly mixed with the desulfurizing agent, increasing the contact area between the gas and the desulfurizing agent, accelerating the desulfurization reaction rate, and improving the working efficiency of the device. When the filter screen 18 needs to be replaced or cleaned, the user can pull the handle 23 outward by hand. The handle 23 will cause the pressure plate 21 and the strong magnet 22 to separate from the docking groove 20 of the metal plate 19. After separation, the user can take out the filter screen 18 placed in the installation groove 17 to replace or clean the filter screen 18. Then, the new filter screen 18 can be placed in the installation groove 17 and fixed again. This allows for the installation and fixing of the filter screen 18, making it convenient for the user to disassemble and clean the filter screen 18 later, reducing the possibility of clogging the filter screen 18 and extending its service life.
