Abstract

The invention relates to a magnesia-method desulfurization and drying all-in-one machine. The magnesia-method desulfurization and drying all-in-one machine comprises a flue gas dry-method dust remover, a spray drying tower, a cyclone dust collector, a sulfuric acid removing tower, a magnesia pulping tank, a high-pressure spray pump, a magnesia material slurry pump, a circulating conveying pump, aplate-and-frame filter, a high-pressure induced draft fan, a magnesium sulfate storage tank, an aeration draught fan and a control system, wherein the flue gas dry-method dust remover is mutually communicated with an external air source and the spray drying tower; the spray drying tower is mutually communicated with the magnesium sulfate storage tank through the high-pressure spray pump and is mutually communicated with the cyclone dust collector; the cyclone dust collector is mutually communicated with the sulfuric acid removing tower; the sulfuric acid removing tower is mutually communicatedwith the high-pressure induced draft fan, the circulating conveying pump, the aeration draught fan and the magnesia material slurry pump respectively. By adopting the magnesia-method desulfurizationand drying all-in-one machine, on one hand, the flexibility and convenience of equipment utilization can be effectively improved, and installation, construction and operation and maintenance cost of equipment are reduced; on the other hand, the requirements of purifying the tail gas, pre-heating and recycling and preparing a high-purity magnesium sulfate monohydrate product are effectively met atthe same time.

Description

technical field [0001] The invention relates to a magnesium oxide desulfurization and drying integrated machine and a construction method, belonging to the technical field of environmental protection. Background technique [0002] At present, domestic flue gas desulfurization is mainly based on calcium desulfurization or double-alkali desulfurization. It is well known that calcium desulfurization is easy to block the pipeline, and the product produced after gas explosion is calcium sulfate, that is, gypsum. The gypsum is of poor grade and has no use value. Waste, and double alkali desulfurization, using sodium hydroxide as a desulfurizer, although it solves the problem of pipeline blockage, the final product generated by the reaction of the desulfurized liquid with lime or calcium hydroxide is still gypsum, which is also waste. Can not fundamentally solve the problem of environmental desulfurization. [0003] At the same time, magnesium oxide desulfurization technology is m...
