Desulfurization and denitrification effect control system in intelligent flue gas treatment

Abstract

The invention belongs to the technical field of environmental protection, and discloses a desulfurization and denitrification effect control system in intelligent flue gas treatment. The system comprises a sulfur dioxide detection module, a nitrogen oxide detection module, a wireless operation module, a single chip control module, an oxygen content control module, a dedusting module, an oxidationmodule, a spray module and a residual liquid recovery module. According to the invention, flue gas treatment can be remotely controlled through the wireless operation module; a worker is prevented from the damage of a harmful gas; the worker can safely desulfurize and denitrify flue gas; the desulfurization and denitration efficiency can be improved through the oxygen content control module; the comprehensive desulfurization efficiency is up to 96%; and the comprehensive denitration efficiency is up to 85%.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a control system for desulfurization and denitrification effects in intelligent flue gas treatment. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Smoke is a mixture of gas and smoke and is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and pyrolysis products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. The harmfulness of smoke to the human body is related to the size of the particles. The most harmful to the human body is the floating dust with a diameter of less than 10um,...

AI Technical Summary

Problems solved by technology

[0005] The flue gas in the existing flue gas treatment has hazardous gas, and the staff controls and processes the flue gas on site, which is likely to threaten the health of the personnel; at the same time, the existing desulfurization and denitrification efficiency is low and the effect is poor

[0006] Existing hazardous gas detection accuracy is low, which cannot provide a basis for reasonable governance

[0007] The design or selection of the existing flue gas separator mainly relies on empirical data, which is highly subjective, and the selected separator often cannot achieve the best oxygen separation effect.
