Learn from the advanced practices of the *Brothers section; there are rewards for correct answers – every response earns a reward, allowing us to grow and mature through these Q&A sessions. Short answer: Working principle of the Venturi scrubber: When dust-containing syngas enters the scrubber nozzle at high speed, it comes into contact with hot water sprayed from the nozzle. The fast-moving gas impacts the liquid, causing it to be thoroughly atomized and thus increasing the surface area for dust removal. A large number of dust particles are wetted by the water. As the dust-laden water droplets slow down due to the diffuser, the pressure difference between them and the wetted gas increases, resulting in an improved dust removal effect.
Correct. Working principle of the Venturi scrubber: When dust-containing syngas enters the scrubber nozzle at high speed, it comes into contact with hot water sprayed from the nozzle. The fast-moving gas impacts the liquid, causing it to be thoroughly atomized and thus increasing the surface area for dust removal. A large number of dust particles are wetted by the water. As the dust-laden water droplets slow down due to the diffuser, the pressure difference between them and the wetted gas increases, resulting in an improved dust removal effect.
When the dust-containing syngas enters the scrubber nozzle at high speed and comes into contact with the hot water sprayed from the nozzle, the fast-moving gas impacts the liquid, causing it to be thoroughly atomized. This increases the surface area for dust removal; many dust particles are wetted by the water. As the dust-containing water droplets slow down due to the diffuser, the pressure difference between them and the wetted scrubbing gas increases, resulting in an improved dust removal effect.
