AI Technical Summary

Problems solved by technology

However, in the actual use of this technology, the denitrification efficiency is low, and the ozone depletion is extremely high. When the emission standard is to be met, the operating cost is extremely high, which cannot be afforded by enterprises, so this technology has not been able to achieve large-scale industrialization.

Embodiment Construction

[0060] The actual purification effect of the desulfurization and denitrification agent described in the present invention will be described below in conjunction with specific embodiments. The embodiments described are for better illustration of the present invention and should not be construed as limiting the claims of the present invention.

[0061] Its operation method is as follows:

[0062]First, the desulfurization and denitrification agent of the present invention is dissolved in ethylene glycol or polyethylene glycol to form a desulfurization and denitrification solution (lean solution 14), which is injected into the lean solution tank 5, and all equipment is turned on for operation. It works like this:

[0063] Such as figure 1 Shown: the pre-purified flue gas 12 with a temperature lower than 80°C (the optimum temperature is below 35°C) enters the absorption tower 2 from the bottom after being pressurized by the booster fan 1, and at the same time, the lean liquid 14...

Abstract

The invention discloses an agent for desulphurization and denitration. The agent is prepared by mixing polyol and / or polymerized polyol substances, polycarboxylic acid substances and alkaline substances; the raw materials are heated to 90 DEG C or above, condensation and / or polymerization are carried out in order to obtain ether and / or ester substances of macromolecule or high polymer. The agent for desulphurization and denitration has wide industrial applications, and is used for simultaneously or separately removing sulfur dioxide and nitrogen oxide in gas; compared with traditional agents for desulphurization and / or denitration, the agent has the advantages of renewable properties without secondary pollution, low energy consumption, low operation cost, high desulphurization and denitration efficiency, and simple operation.

Description

technical field [0001] The invention relates to the industrial field of gas desulfurization and / or denitrification, in particular to a desulfurization and denitrification agent for desulfurization and / or denitrification of flue gas or various combustion tail (waste) gases. Background technique [0002] The combustion of fossil fuels produces a large amount of flue gas that is discharged into the atmosphere, which contains sulfur dioxide, sulfur trioxide, hydrogen chloride, hydrogen fluoride, nitrogen oxides and a small amount of harmful organic substances, as well as a large amount of dust. The tiny hydrophilic particles in these dust And non-hydrophilic particles (mainly calcium salt particles, aluminum salt particles, magnesium salt particles, titanium salt particles, iron salt particles, lead salt particles, zinc salt particles, cobalt salt particles, rare earth element particles, radioactive element particles and other Harmful element particles, and mineral particles suc...
