Abstract

The invention discloses a container type additive solution feeding system for removing mercury from flue gas. The container type additive solution feeding system comprises an additive solution storage system, a feeding system, a washing system, an electric control device and related pipelines, and is characterized in that the additive solution storage system comprises at least one additive delivery pump, additive storage tanks and delivery pipes, an inlet of the additive solution storage system is connected with external additive solution, and an outlet of the additive solution storage system is connected with the feeding system; the feeding system is communicated with an additive input point by a metering pump via a feeding pipeline; system washing water can be supplied by the washing system, the mentioned devices are controlled by the electric control device, and the mentioned devices and the related pipelines are arranged in a container in a communicated manner. The container type additive solution feeding system has the advantages that the container type additive solution feeding system can flexibly move and can be quickly deployed to different flue gas treatment sites; the container type additive solution feeding system is low in investment, small in occupied area, high in reaction speed and automation degree and convenient to move and is environmentally friendly, and energy can be saved.

Description

technical field [0001] The invention belongs to the field of energy saving and environmental protection, in particular to a container-type additive solution dosing system for flue gas mercury removal in the field of air pollution control. Background technique [0002] With the development of economy, the society's consumption of coal, oil and other energy sources continues to increase. The combustion and utilization of these fuels will produce SOx, NOx, dust, mercury and many other air pollutants. Among them, mercury, as a heavy metal pollutant, can pass through breathing and skin contact. After entering the human body through diet and other methods, it will lead to various diseases of the nervous system and cardiovascular system, which will cause great harm to human health. [0003] The oxidation and absorption technology of mercury has become an efficient technology for mercury control in flue gas. 0 Hg in flue gas 2+ The conversion of Hg2+ is used to remove mercury from...
