Description

Technical Field

[0001] The invention relates to the field of highway transportation, and in particular to a fume recovery and purification device. Background Art

[0002] With the acceleration of industrialization, flue gas emissions have become one of the main sources of air pollution. The various harmful gases and particulate matter contained in them pose a serious threat to the environment and human health. Therefore, efficient purification of flue gas, especially the removal of gaseous pollutants and soot particles, has become an important issue to be solved in the field of environmental protection. In existing flue gas purification technologies, the filter structure, as a key component, bears the heavy responsibility of intercepting soot particles in the flue gas. These filter structures are usually designed as porous media or mesh structures, which retain soot particles on their surface or inside through physical blocking. However, this traditional filtering method faces many challenges in practical applications:

[0003] 1. As the filtering process continues, more and more smoke particles are intercepted on the filter, causing the pores of the filter to gradually decrease or even become completely blocked, seriously affecting the flow efficiency and purification effect of the flue gas; this not only increases the operating resistance of the system, but may also cause equipment failures, requiring frequent cleaning and maintenance.

[0004] 2. After the filtration is completed, the filtered flue gas needs to be processed by water washing. In the prior art, multiple mechanisms such as air pumps and water pumps are required, which increases the complexity and cost of the equipment. Summary of the invention

[0033] In the present invention, when in use, the motor 7 is started, and the motor 7 drives the second rotating shaft 18 to rotate, thereby rotating the rotating disk 19.

After entering the water washing box 2, the piston block 22 on the right side reciprocates up and down, and cooperates with the second one-way valve in the third one-way tube 26 and the fourth one-way tube 27 to draw water in the water tank 12, and then spray it out from the multiple water spray ports 30 at the annular cavity 29. In this way, water washing can be achieved, and only one driving source is needed for water washing and gas flow, which reduces the actual cost.

[0035] In addition, the rotation of the second rotating shaft 18 will also rotate the first rotating shaft 13 through the use of the transmission belt 17 and the pulley 16. The rotation of the first rotating shaft 13 will rotate the filter cartridge 5 through the transmission of the second bevel gear 14 and the first bevel gear 15, thereby rotating it relative to the brush 31, achieving surface self-cleaning and achieving an anti-clogging effect.
