Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to waste gas treatment equipment for high specific surface area calcium hydroxide production. Background Art

[0002] Waste gas treatment equipment mainly refers to an environmental protection equipment that uses different process technologies to recycle or remove and reduce harmful components in exhaust gas to protect the environment and purify the air, so that our environment is not polluted.

[0003] High specific surface area calcium hydroxide is an important chemical raw material, which is widely used in water treatment, pharmaceuticals, building materials and other fields. Its preparation process has an important impact on product quality and production cost. When producing high specific surface area calcium hydroxide, it is necessary to select high-quality lime as raw material. High-quality lime is selected as raw material, and after crushing, screening and other process treatments, lime particles with a particle size of 1-3mm are obtained. When the lime is crushed, the lime powder is exposed to the air, and some powder will drift with the air. In the prior art, the lime powder is sucked into the waste gas treatment equipment for filtration and then the air is discharged, but the filtered lime powder will remain in the waste gas treatment equipment. When the lime powder inside the waste gas treatment equipment reaches a certain level, the waste gas treatment equipment will be blocked, resulting in poor filtering effect, and the lime powder needs to be cleaned out, but the lime powder will fly when the waste gas treatment equipment is opened, and may be inhaled into the body, which will cause irritation and damage to the respiratory tract and nasal mucosa, and will cause symptoms of sneezing or coughing, leading to symptoms such as esophageal burns, indigestion, and hypercalcemia in the human body. At this time, the lime powder needs to be centrally processed. Utility Model Content
