Problems solved by technology
However, the current flue gas arsenic collection method cannot effectively deal with the arsenic-containing flue gas under fluctuating conditions. During the flue gas cooling process, condensation and dripping water will occur, which will severely corrode and damage equipment, endanger the environment and human health, and affect subsequent processes.
Especially during the commissioning of the arsenic collection system and the process accident of the smelter, flue gas fluctuations lead to a cumulative increase in the high arsenic load, which cannot be discharged, resulting in overall shutdown and affecting the total output during the production period

The invention provides a method and a system for recycling arsenic from smoke gas. Wherein the method for recycling arsenic from the smoke gas comprises the following steps: carrying out dust removing and cooling treatment for the smoke gas so as to gain low temperature purified smoke gas, and carrying out arsenic removal treatment for the low temperature purified smoke gas so as to obtain smoke gas and arsenic smoke dust, which can be subjected to advanced treatment. Through the utilization of the method, arsenic in the smoke gas can be effectively removed; and the producing of the dangerous waste pollution can be avoided.
Description
technical field [0001] The invention relates to the fields of metallurgy and environmental protection. In particular, it relates to a method and system for recovering arsenic from flue gas. Background technique [0002] In the field of metallurgy, a large amount of arsenic-containing flue gas will be generated during the smelting process of concentrates with high arsenic content. Appropriate methods must be used to remove and recycle arsenic in the flue gas to avoid hazardous waste pollution. However, the current method of collecting arsenic from flue gas cannot effectively deal with arsenic-containing flue gas under fluctuating conditions. During the cooling process of flue gas, dew condensation and dripping will occur, which will severely corrode and damage equipment, endanger the environment and human health, and affect subsequent processes. Especially during the commissioning of the arsenic collection system and process accidents in the smelter, flue gas fluctuations le...
