Abstract
The invention discloses a desulfurizer for a gas-fired boiler.The desulfurizer is prepared from, by weight, 22-28 parts of sodium hydroxide, 40-48 parts of lime, 13-15 parts of magnesium carbonate, 5-8 parts of sulfoxide, 3-7 parts of MgO, 12-14 parts of activated carbon and 8-10 parts of quaternary ammonium sulfonated cobalt phthalocyanine.The desulfurizer has the advantages that the catalyst quaternary ammonium sulfonated cobalt phthalocyanine is used for carrying out adsorption desulfurization on dusty gas, and thus sulfide in dusty gas is effectively removed.
Description
Technical field
The present invention relates to boiler desulfurization technology, especially, relate to a kind of desulfurizing agent for gas fired-boiler.
Background technology
Dusty gas enters central canal from device bottom, after scrubbed water (certain density NaOH solution) shower humidification, and impact liquid level, finally wait until that form realizes the dust removal process of compound action with atomization, foam, liquid film.
Liquid after desulfation dust-extraction device absorbs, flows through neutralization pond voluntarily, fully reacts under the effect of eddy flow inertia, finally precipitates its mud and impurity, periodic cleaning in sedimentation tank, and clear liquid enters alkali liquor pond (regulation PH), again recycles.
Boiler desulfurization dedusting particular importance on formula, because boiler often uninterruptedly running in 24 hours, needs anticorrosion and high temperature resistant has extra high requirement.
Summary of the invention
Present invention aim at providing a kind of desulfurizing agent for gas fired-boiler, to solve in prior art boiler desulfurization dedusting to anticorrosion and the high temperature resistant problem having high request.
For achieving the above object, the present invention provides a kind of desulfurizing agent for gas fired-boiler, and wherein, described desulfurizing agent is made up of following component in parts by weight:

Calx 40-48 part；
Magnesium carbonate 13-15 part；
Sulfoxide 5-8 part；
MgO 3-7 part；
Activated carbon 12-14 part；And
Quaternary ammonium sulfonated phthalocyanine cobalt 8-10 part.
Further, the invention provides a kind of desulfurizing agent for gas fired-boiler, wherein, described desulfurizing agent is made up of following component in parts by weight:
Sodium hydroxide 22 parts；40 parts of Calx；Magnesium carbonate 13 parts；Sulfoxide 6 parts；MgO 5 parts；Activated carbon 12 parts；And quaternary ammonium sulfonated phthalocyanine cobalt 8 parts.
Further, the invention provides a kind of desulfurizing agent for gas fired-boiler, wherein, described desulfurizing agent is made up of following component in parts by weight:
Sodium hydroxide 28 parts；48 parts of Calx；Magnesium carbonate 15 parts；Sulfoxide 6 parts；MgO 7 parts；Activated carbon 13 parts；And quaternary ammonium sulfonated phthalocyanine cobalt 9 parts.
The method have the advantages that and utilize catalyst quaternary ammonium sulfonated phthalocyanine cobalt to carry out dusty gas adsorbing desulfurization, can not only effectively remove the sulfide in dusty gas, and anticorrosion and high temperature resistant.
