Description

Technical Field

[0001] The invention relates to the technical field of electric power engineering, and in particular to a fume purification treatment mechanism for thermal power generation. Background Art

[0002] Coal combustion emits 24 million tons of SO2 into the atmosphere every year, as well as a large amount of smoke. The large amount of SO2 pollution and the resulting acid precipitation pollution have caused serious harm to the human body, agriculture, forests, fisheries, materials, etc. In particular, after the boiler is burned, it will produce a large amount of flue gas, so now it is not allowed to directly discharge untreated flue gas. All boiler flue gas needs to be purified before it can be discharged. However, the traditional flue gas purification treatment device has a low treatment efficiency and cannot meet the national safety emission standards.

[0003] The invention patent with patent number CN202223093176.5 discloses a thermal power generation flue gas purification treatment mechanism. The fan of the invention draws the flue gas into the connecting pipe, and then enters the inner side of the treatment box. Through the rotation of connecting shaft one and connecting shaft two, the zeolite molecular sieve is driven to rotate, and the flue gas can be filtered and purified. The purified flue gas enters the inner side of the discharge box through the installation pipe, and the water inside the water tank is pumped into the connecting pipe one, the connecting pipe two, and then into the arc-shaped liquid storage box through the water pump. The harmful substances in the flue gas can be degraded by spraying through the nozzle, and the harmful substances and odors can be absorbed by the activated carbon layer, thereby solving the problem of transmission. The traditional flue gas purification treatment device has a low treatment efficiency and cannot meet the national safety emission standards. The flue gas contains harmful smoke, sulfides, etc., which seriously harm the environment and cause serious pollution to the atmosphere when the flue gas is discharged. If people inhale untreated flue gas into their bodies, it will affect people's health in the long run and reduce the safety of the flue gas purification device during use. Although this patent solves the above problems, there is still the problem of insufficient filtration efficiency. Therefore, it is very necessary to design a thermal power generation flue gas purification treatment mechanism that can accelerate the absorption of harmful molecules by molecular sieves, improve filtration efficiency, and increase emission speed. Summary of the invention

[0006] According to the above technical scheme, a particle adsorption device is provided inside the filter barrel, and the particle adsorption device includes a sliding structure and a circulation structure.

When the activated carbon slides from the spiral plate to the bottom of the filter barrel, it is squeezed into the bottom of the propulsion sleeve and is pushed up by the propulsion auger.

[0007] According to the above technical solution, a condensation device is provided below the crank, and the condensation device includes a condensation structure and a vortex structure.

At this time, the rotating shaft drives the hollow column to rotate, and the hollow column drives the stirring paddle to rotate. The stirring paddle stirs the liquid, so that the impurities that have not been filtered out in the liquid are filtered again. The impurities are separated from the liquid after stirring and settle to the bottom of the separation tank, and then the filtered liquid is discharged through the discharge pipe, thereby minimizing the impact of flue gas emissions on the environment without affecting the efficiency. The hollow column drives the stirring paddle to rotate while the stirring paddle drives the moving shaft to rotate. Because the moving shaft is sleeved on the surface of the reciprocating screw, it moves up and down while rotating, thereby driving the stirring paddle to move up and down in the slide groove, so that the stirring paddle spirally rotates, which increases the stirring area while facilitating the destruction of the cohesion of the liquid, making it easier for impurities to settle.

[0033] The second one-way valve 49 is opened, and the flue gas liquid condensed into liquid in the condensation tank 44 flows into the separation tank 51 from the second one-way valve 49.

Due to the influence of the hollow column 53, the stirring paddle 54 rotates, and at the same time, the stirring paddle 54 drives the moving shaft 57 to rotate. Since the moving shaft 57 is sleeved on the surface of the reciprocating screw 56, it moves up and down while rotating, thereby driving the stirring paddle 54 to move up and down in the slide groove 55, so that the stirring paddle 54 spirally rotates, which increases the stirring area and makes it easier to destroy the cohesion of the liquid, making it easier for impurities to settle. After the impurities are settled to the bottom of the separation tank 51, the liquid can be discharged to clean the impurities out through the cleaning pipe 58.
