Problems solved by technology

In the existing equipment, limestone water is used to desulfurize the gas. In the desulfurization process, generally only one layer of spray is installed, and the gas can only be in contact with the limestone water spray once, so that the desulfurization effect is not good, and a large amount of desulfurization cannot be carried out. Fog, unable to meet emission standards

Abstract

The invention discloses wet desulphurization and dust removal equipment for industrial waste gas and a use method thereof, and belongs to the technical field of industrial waste gas desulfurization. The equipment includes an outer cylinder, wherein a support is fixedly mounted below the outer side of the outer cylinder, and supporting legs are fixed below the support. According to the equipment and the use method thereof, the contact area with limestone water is increased, the reaction efficiency is improved, internal water backflow is prevented, the situation that gas rises too fast and cannot make contact with a spraying device is prevented, the contact time is prolonged, the treatment efficiency is improved, and the limestone water sprayed out of a spray head makes full contact with the gas, thus improving the desulphurization effect, forming a wet desulphurization cycle, increasing the utilization efficiency, reducing the waste of resources, preventing condensate water residues inside, avoiding secondary pollution caused by long-time residues, improving the condensation conveying efficiency, strictly controlling the gas emission quality, protecting the environment from being polluted, improving the desulphurization quality, reducing the waste of heat energy and increasing the treatment benefits.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas desulfurization, in particular to a wet desulfurization and dust removal equipment for industrial waste gas and a use method thereof. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during fuel combustion and production processes in the factory area. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist) lead mercury, beryllium compounds, smoke and productive dust, which will pollute the air when discharged into the atmosphere. These substances enter the human body through the respiratory tract in different ways, some directly cause harm, and some have a cumulative effect, which will seriously endanger human health. Different substances will have different effects. Wet el...
