Abstract
Description
Technical Field
[0001] This utility model relates to the field of wet dust collector technology, and in particular to a wet dust collector sludge drying and collection device. Background Technology
[0002] A wet scrubber is a device that brings dust-laden gas into close contact with a liquid (usually water). It uses the inertial collisions of water droplets and particles, along with other forces, to capture the particles or increase their size. When dust particles in the gas pass through a wet scrubber, they are captured by the water mist or film through inertial collisions and interception, gradually aggregating into larger particles. These particles eventually settle to the bottom of the scrubber due to gravity, forming sludge.
[0003] Wet scrubbers generate a large amount of sludge during operation. This sludge contains high levels of moisture and harmful substances, and needs to be treated promptly to avoid secondary pollution and environmental risks. Traditional sludge treatment methods include natural drying and mechanical dehydration, but these methods have problems such as low treatment efficiency, high energy consumption, and serious environmental pollution.
