Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for converter gas, and particularly to a low-temperature and low-pressure dust removal device. Background Art

[0002] Converter gas is a medium calorific value gaseous fuel in the iron and steel industry, originating from the high-temperature reaction of carbon and oxygen during the steelmaking process. Its main components are carbon monoxide (about 60%-80%), carbon dioxide (about 15%-20%), as well as nitrogen, hydrogen and trace oxygen. It can be used alone as a fuel for industrial furnaces or mixed with other gases. However, it should be noted that its high-concentration carbon monoxide is extremely toxic, and leakage prevention is required during storage, transportation and use. In the recovery and treatment of converter gas, low-temperature technology shows unique advantages. At low temperatures, components such as SO3 are easily condensed and adsorbed by dust, improving the dust characteristics and enhancing the dust removal efficiency. At the same time, low temperature reduces the flue gas volume, increases the dust collection area, and prolongs the dust residence time, further improving the dust removal effect. In addition, low-temperature technologies such as low-temperature economizers can recover heat, achieve energy conservation, and reduce SO3 and PM2.5 emissions, meeting environmental protection requirements. However, the ash cleaning of traditional dust removal devices is cumbersome, and the dust-holding capacity decreases after ash cleaning. When manually cleaning, the system needs to be shut down, affecting the production progress and efficiency. Therefore, optimizing the dust removal device and reducing the shutdown time have become the key to improving the treatment efficiency of converter gas. In response to the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution.

[0017] According to the attached Figures 1-5It is concluded that the converter gas is input through the external pipe 4 on the side of the device, and after being connected by the adapter 3, it flows into the extension pipe 2 and then into the device shell 1. The honeycomb matrix condenser 20 will cool the converter gas. After the converter gas is cooled by the honeycomb matrix condenser 20, the dust in the converter gas will settle downward to the greatest extent. The external pipe 4 on the top of the device will be connected to the negative pressure, so that the cooled converter gas will flow out of the device shell 1 from the extension pipe 2 on the top of the device and the adapter 3, and flow into the reaction container of the next stage from the external pipe 4; when the dust removal operation is required in the device shell 1, the progressive power motor 6 in the progressive power housing 5 is driven, so that the transmission threaded rod 7 is driven to rotate, so that the meshing displacement sleeve 8 is slowly pushed and displaced with the assistance of the auxiliary displacement hub 9. When the meshing displacement sleeve 8 is displaced to the end of the device shell 1, it is driven to reset. During the process again, the operation of the pushing motor 10 in the shell causes the reciprocating swing component to continuously scrub the surface of the honeycomb matrix condenser 20, thereby completing the cleaning operation of the honeycomb matrix condenser 20. The non-return valve arranged on the adapter 3 can prevent the occurrence of backflow, which greatly improves the safety of the device. The observation porthole arranged on the device shell 1 can facilitate the observation of the situation inside the device shell 1. The operation panel arranged on the device shell 1 can operate and control the entire device. When cleaning After the operation is completed, the dust in the device housing 1 can be collected and processed centrally through the dust cleaning closed door provided on the device housing 1; when the push motor 10 in the shell is running, the swing push block 11 is driven to rotate, and the rotating swing push block 11 causes the displacement push column 13 to be reciprocated, so that the special-shaped toggle plate 17 is pulled and rotated relying on the rotating shaft, and the spring positioning block 15 cooperates with the reset auxiliary spring 16 to make the special-shaped toggle plate 17 always in a reset movement trend, and because the special-shaped toggle plate 17 is meshed with the meshing transmission column 18, and the meshing transmission column 18 can drive the swing cleaning brush 19 to move, it can be concluded that when the push motor 10 in the shell rotates, the swing cleaning brush 1 9 is driven to swing back and forth, and cleans and brushes the surface of the honeycomb matrix condenser 20; the booster air pump is connected to the external air pipe 22, and the pressurized air is blown into the built-in air pipe 23 through the gas connection valve body 21, and the reciprocating intermittent pressure storage component on the air pipe covering shell 26 can further pressurize and store the air, and intermittently blow it into the high-temperature resistant branch air rod 24, and then blow it to the honeycomb matrix condenser 20 below through multiple pulse nozzles 25, and blow the dust in the gap above it downward.

As a result, the pulse-related runner 29 is driven to rotate through the rotating shaft, causing the driving posts 32 on the runner to continuously slide on the chute 31 on the guiding transmission frame 30. Consequently, the guiding transmission frame 30 continuously reciprocates and inserts into the air pipe covering shell 26, making the air-blocking block 33 inside the shell continuously slide within the air pipe covering shell 26, intermittently closing or opening the built-in air pipe 23. The air pump fills air into the built-in air pipe 23, which first flows into the air pipe covering shell 26. When the air-blocking block 33 in the shell blocks the built-in air pipe 23, gas will be accumulated. When the air-blocking block 33 separates from the built-in air pipe 23, the accumulated gas will be filled into the high-temperature-resistant branch air rod 24 and rush towards the honeycomb matrix condenser 20 below through multiple pulse nozzles 25. The reciprocating gas impulse will wash the dust on the honeycomb matrix condenser 20 downwards, thus completing the cleaning operation.
