Problems solved by technology
Most water mist dust collectors mainly use nozzles to spray dust-containing gas, and absorb and fuse the dust in the gas through water mist, so as to achieve the purpose of purifying the air, but this kind of water mist dust collector has low dust removal efficiency and waste of water resources. And other issues
Especially for high-temperature dust-laden gas, the heat energy carried by the high-temperature dust-laden gas is transferred to the dust-laden water droplets after dedusting by water mist, and it is not recycled effectively, resulting in a great waste of heat energy

The invention discloses a water mist dust removal device for a calcium hydroxide production line and the calcium hydroxide production line. The water mist dust removal device comprises a dust collection assembly, a mist spray dust removal assembly, a water dust removal assembly, a fan and a hot mixed slurry water conveying assembly. The dust collection assembly comprises a dust collection chamber for collecting high-temperature dust-containing gas; the spraying dust removal assembly comprises a nozzle, a dust removal pump and a water tank, the nozzle is arranged in the dust collection chamber and communicates with the water tank through the dust removal pump, and the water tank communicates with a liquid outlet of the dust collection chamber; the water dust removal assembly comprises a dust removal cylinder, and a proper amount of water is contained in the dust removal cylinder; and the hot mixed slurry water conveying assembly is used for conveying the high-temperature water in the water tank to an external device. High-temperature dusty gas released in the quick lime digestion process is combined with water mist to form high-temperature turbid slurry hot water, a layer containing more dust is used for quick lime digestion slurry, quick lime digestion is promoted, and high-quality slaked lime powder can be obtained; and a layer containing less dust is used for atomization dust removal again, so that cyclic utilization of water resources is realized, and dust removal is more efficient and energy-saving.
Description
technical field [0001] The invention relates to the technical field of dedusting, in particular to a water mist dedusting device used in a calcium hydroxide production line and a calcium hydroxide production line. Background technique [0002] Dust collectors are divided into dry mechanical dust collectors, wet dust collectors and bag dust collectors. Dust collectors are devices that separate dust from dust-containing gases. They are called dust collectors or dust removal equipment. The dust hood is a complete set of equipment that transports the dust-laden gas to the dust removal device through the pipeline gas path, and collects the dust in the dust removal device after gas-solid separation, and the clean gas is introduced into the main pipe or directly discharged into the atmosphere. It is the dust removal system, and the dust collector is an important part of the system. The water mist dust collector is a typical wet dust collector. [0003] In the prior art, there are...
