Stack desulfurization device

Abstract

The invention relates to a smoke exhaust and desulfurization device, comprising a body, at least a bracket, a sprayer, and multiple filling parts. A channel for discharging smoke is set on the body. Every brackets and sprayer are set in the channel and filling parts are set on the bracket. The sprayer sprays seawater towards all brackets so that surfaces of all filling parts touch seawater. When exhaust smoke makes round of gaps among filling parts, not only the time of mixing reaction of exhaust smoke and seawater is added but also desulfurization cost is decreased.

Description

technical field [0001] The present invention is related to environmental protection equipment, in particular to a flue gas desulfurization device. Background technique [0002] When using burners such as industrial boilers or incinerators for combustion work, since the fuels used in the burners are fossil fuels, industrial wastes or municipal wastes, the waste gas generated by the fuels after combustion usually contains Contains gaseous sulfur oxides (such as sulfur dioxide, sulfur trioxide, etc.), and in order to avoid continued air pollution and achieve the purpose of environmental protection, the exhaust gas generated by the burner must be separated and absorbed by a flue gas desulfurization device. The exhaust gas can not be discharged until the gaseous sulfur oxides in the exhaust gas reach the dischargeable standard. [0003] Please refer to FIG. 4 , the general structure of the flue gas desulfurization device (90) includes a hollow body (92), the body (92) has an inl...

Problems solved by technology

[0004] In the structure of the above-mentioned exhaust gas desulfurization device (90), since the depth of the liquid filter layer in each tray (96) is only a few centimeters deep, when the exhaust gas passes through the liquid filter layer, the gaseous sulfur oxides in the exhaust gas and the alkaline desulfurization The reaction time between the liquids is limited, and the gaseous sulfur oxides cannot be fully mixed with the desulfurization liquid, which makes the desulfurization efficiency poor. Therefore, there is another kind of flue gas desulfurization device, which mainly installs a support frame inside the body and most of them are stacked on the The filler on the support frame, there is a gap between the support frame and the filler for exhaust gas to pass through. When the exhaust gas flows through the inside of the body, the exhaust gas will be forced to go around between the fillers through the above gap to increase the exhaust gas. The mixing time between the SOx and the desulfurization liquid

[0005] However, when using the various exhaust gas desulfurization devices mentioned above, alkaline desulfurization liquid must be used to neutralize the sulfur oxides in the exhaust gas. Due to the high cost of alkaline desulfurization liquid, the overall desulfurization of the exhaust gas desulfurization device is also increased. cost
