Description
Technical Field
[0001] The utility model relates to the technical field of dust removal towers, in particular to a water film dust removal tower for removing silicon dioxide dust. Background Art
[0002] A water film dust collector is a purification device that uses dust-containing gas to impact the inner wall of the dust collector or other special components to form a water film in some way, so that the dust is captured by the water film and the gas is purified. Common water film dust collectors include impact water film dust collectors, louver water film dust collectors, and centrifugal water film dust collectors.
[0003] The appearance of the water film dust collector is a circular cylinder. Water enters the cylinder from the spray pipe in the upper part of the dust collector, forming a layer of water film on the inner wall of the entire cylinder and flowing from top to bottom. The flue gas enters tangentially from the lower part of the cylinder and rotates and rises in the cylinder. The dust-containing gas always rubs against the water film on the inner wall of the cylinder under the action of centrifugal force. In this way, the dust-containing gas is moistened by the water film, and the dust particles flow to the bottom of the dust collector with the water. The common water film dust collector is to set a spray hole on the spray pipe, and water is sprayed on the inner wall of the cylinder through the spray hole. However, the method of spraying the water to the cylinder wall through the spray hole is prone to uneven spraying, which affects the dust removal efficiency.
[0004] Therefore, those skilled in the art provide a water film dust removal tower for removing silicon dioxide dust to solve the problems raised in the above background technology. Utility Model Content
