Problems solved by technology

[0004] The above-mentioned invented dust removal and desulfurization process in the smelting process, although the setting is reasonable to achieve efficient desulfurization and dust removal of flue gas, shorten the process and reduce process configuration, but the desulfurization products cannot be recovered and utilized, and the economic benefits are not high. Therefore, At present, there is an urgent need to develop a metal smelting desulfurization and dust removal process for environmental protection dust collectors to meet market demand.

Embodiment 1

[0024] A metal smelting desulfurization and dedusting process for an environmental protection dust collector, comprising the following steps:

[0025] (1) Dust removal: introduce the flue gas produced in the smelting production process into the cyclone dust collector for dust removal treatment;

[0026] (2) Preparation of desulfurization liquid;

[0027] (3) Desulfurization treatment: The flue gas after dust removal by the cyclone dust collector is pressurized by the booster fan and then sent to the desulfurization tower, and the desulfurization liquid in the circulation pool is supplied to the nozzle in the desulfurization tower through the circulation pump, and is sprayed by the atomization nozzle. The flue gas is sprayed, the desulfurization liquid is in countercurrent contact with the smelting flue gas, and the zinc sulfite or zinc bisulfite slurry reacted with the smelting flue gas falls into the circulating pool;

[0028] (4) Zinc sulfite or zinc bisulfite slurry: Use a...

Abstract

The invention relates to the technology field of metal-smelting processing for an environmentally friendly deduster, and specifically relates to a metal-smelting desulfurizing and dedusting technologyfor an environmentally friendly deduster. The technology comprises following steps: (1) dedusting; (2) preparing a desulfurizing solution; (3) carrying out desulfurization; (4) preparing zinc sulfiteslurry or zinc hydrogen sulfite slurry; and (5) preparing a zinc sulfate solution. The provided technology can effectively recover resources, and prepares a desulfurizer from an existing product. Thedesulfurization product is taken as a finished product and recovered, good economic benefits are created for the enterprises; the technological process is simplified, the sulfides in flue gas in metal smelting are recovered and utilized; the goals of sulfur removal and dust removal are realized; and the secondary pollution of sulfides and dusts in smelting flue gas to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of metal smelting processing for environmental protection dust collectors, in particular to a metal smelting desulfurization and dust removal process for environmental protection dust collectors. Background technique [0002] The equipment that separates dust from flue gas is called dust collector or dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life and difficulty of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production. [0003] For example, the Chinese invention patent with the publication number CN105251329A discloses a dust removal and...
