Abstract

The invention provides a calcium hydroxide production line and relates to the field of calcium hydroxide production. The calcium hydroxide production line comprises a digester, hierarchical atomizers, a purifier, a decompression filter, a sewage treater, a fan and a high pressure pump, wherein the digester comprises an inner layer and an outer layer, wherein the outer layer is a heat exchange water layer and the inner layer is a digestion chamber; a water spraying hole is formed in an upper screw stirring shaft and arranged under a feeding hole; an exhaust opening is arranged on the digester on the other side opposite to the feeding hole; the exhaust opening is communicated with the gas inlet of the purifier by virtue of the hierarchical atomizers and a pipeline; the purifier is an airtight hollow chamber with a gas inlet and a gas outlet; a plurality of rows of C-shaped dust collectors are arranged inside the purifier; the decompression filter is a housing defined by a filter screen and provided with a gas inlet; the cross section of the bottom of the decompression filter is V-shaped; the bottom of the sewage treater is funnel-shaped; the sewage treater is communicated with the water inlet of the sewage high pressure pump by use of a pipeline. The calcium hydroxide production line is capable of reducing the production cost and reducing the environmental pollution.

Description

technical field [0001] The invention relates to the field of calcium hydroxide production, and is a complete set of related equipment for digesting and producing calcium oxide and gas purification treatment, specifically a calcium hydroxide production line. Background technique [0002] Calcium hydroxide is an industrial product produced by the reaction of calcium oxide and water, and is widely used. [0003] During the production of calcium hydroxide, a large amount of dusty steam, carbon dioxide and heat will be generated. The dust-laden steam in the process of calcium oxide digestion has serious environmental pollution. As the public pays more and more attention to environmental protection, higher requirements are put forward for the production of calcium hydroxide. [0004] In the prior art equipment, the equipment process is simple, resulting in energy loss and environmental pollution. Some equipment is equipped with dust removal and exhaust gas treatment equipment, b...
