Lime water recyclable desulfurization and denitrification device applied to flue gas treatment

Abstract

The invention discloses a lime water recyclable desulfurization and denitrification device applied to flue gas treatment. The device comprises a first mounting plate, wherein one side of the first mounting plate is fixedly connected with a second mounting plate, and two first fixed supporting legs are fixedly mounted on one side of the top end of the first mounting plate; and a desulfurization barrel is fixedly connected between the top ends of the two first fixed supporting legs. The flue gas to be desulfurized and denitrated passes through the inside of the desulfurization barrel, lime water reacts with sulfides in the flue gas, the desulfurized flue gas enters the denitration barrel and reacts with nitrogen water vapor for desulfurization, the operation steps are relatively simple, emission of harmful substances in the flue gas is effectively avoided, and when the water level in the desulfurization barrel reaches a certain height, turbid liquid flows into the settling vat through the turbid liquid guide pipe, is filtered and settled, and can be pumped into the corrugated pipe through the electric water pump for recycling lime water, so that water resources are saved, and the desulfurization reaction rate can be increased by heat release when lime is in contact with water.

Description

technical field [0001] The invention relates to the field of industrial flue gas treatment, in particular to a recyclable desulfurization and denitrification device for lime water used in flue gas treatment. Background technique [0002] Industrial flue gas is generally industrial waste gas generated during the production process in industrial sites. Different treatment methods are adopted for industrial flue gas according to the harmful components contained in the flue gas, and the most harmful thing in industrial flue gas is sulfide The industrial waste gas of nitrogen oxides and nitrogen oxides has a certain degree of toxicity and is more serious to the environment. It cannot be discharged directly without desulfurization and denitrification process. [0003] Flue gas treatment devices on the market today: [0004] (1) Often only a single sulfide or nitrogen oxide compound in the flue gas can be treated, and subsequent desulfurization or denitrification treatment is requ...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a desulfurization and denitrification device for recyclable lime water used in flue gas treatment, so as to solve the problem mentioned in the background technology that current flue gas treatment devices can only treat single sulfide or nitrogen oxide in flue gas. Compounds are treated and lime water is often used once and then discharged, which is a serious problem of wasting water
