The exhaust and dust filter system is a complete set of devices used to remove the dusty fumes generated during drying and mixing processes by filtering them. In the impact water dust removal system, the dusty gas enters the intake chamber and then impacts against the washing liquid; driven by inertial force, it moves through an “S”-shaped blade channel at a speed of 10–35 m/s, allowing for thorough contact between the gas and the liquid, so that dust particles are captured by the liquid droplets. The purified gas passes through the gas-liquid separation chamber and the water baffle, and is discharged after water droplets are removed. The dust particles settle at the bottom of the funnel and are removed periodically. The water level inside the unit is controlled by an overflow tank, which is equipped with an automatic water level control device to maintain a constant level of water in the dust collector, thereby ensuring stable dust removal efficiency. If the dust collector is small, a simple float can be used to control the water level. It is suitable for the treatment of flue gases with high temperatures and high humidity, as well as non-fibrous dusts. Dust collector 1: The “Mingtian” series of mobile dust collectors, as well as stainless steel dust collectors and standalone bag-type dust collection units, are new products designed based on foreign-made equipment, offering an economical and efficient solution for on-site dust removal.

An answer: A dust removal system is a local exhaust system, usually consisting of an exhaust hood, ducts, a dust collector (device), a fan, and an exhaust stack. 【2】What are the common methods for adjusting the air volume in a gas purification system? Answer: Air volume adjustment is achieved by adjusting the opening of valves, hydraulic couplings, and frequency converters in the piping system, thereby changing the pressure losses in various sections of the system. This ensures that the air volume in each section meets the required levels and maintains the system’s optimal operating conditions. 【3】In air pollution control projects, why is it necessary to cool high-temperature flue gas?
