High efficiency wet process flue gas desulfurization synergist

Abstract

The invention discloses a high efficiency wet process flue gas desulfurization synergist. The desulfurization synergist is prepared from the following raw materials in parts by weight: 50 to 60 partsof high molecular hydroxyl fatty acid salicylic acid, 10 to 15 parts of sodium polyacrylate, 15 to 20 parts of sodium benzoate, 10 to 15 parts of sodium diacetate, 30 to 40 parts of carboxymethylcellulose sodium, 20 to 30 parts of aromatic carboxylate, 10 to 15 parts of sodium citrate, 20 to 30 parts of sodium alkylbenzenesulfonate, wherein sodium benzoate, sodium diacetate, carboxymethylcellulosesodium are organic acid salt, sodium alkylbenzenesulfonate is used as a dispersant in the synergist. The desulfurization synergist is prepared from 55 parts of high molecular hydroxyl fatty acid salicylic acid, 12 parts of sodium polyacrylate, 18 parts of sodium benzoate, 13 parts of sodium diacetate, 35 parts of carboxymethylcellulose sodium, 25 parts of aromatic carboxylate, 12 parts of sodiumcitrate, 25 parts of sodium alkylbenzenesulfonate. The desulfurization synergist provided by the invention has the advantages that the utilization ratio of limestone is increased, the power consumption of a system is reduced, and the effect of energy saving and emission reduction is very obvious, and at the same time, the purity of gypsum is improved.

Description

technical field [0001] The invention relates to a high-efficiency wet flue gas desulfurization synergist. Background technique [0002] The pH of the absorption tower slurry is the most important operating parameter of the desulfurization system. The adjustment of pH not only affects the desulfurization efficiency of the system, but also affects the amount of limestone, the quality of gypsum and the calcium-sulfur ratio, and affects the dehydration performance of gypsum. The higher the pH value, the higher the desulfurization efficiency, but it will inhibit the progress of the desulfurization reaction, resulting in low utilization rate of limestone, increased electricity consumption, and the greater the calcium-sulfur ratio, the lower the purity of gypsum. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to solve the deficiencies in the prior art, and provide a high-efficiency wet flue gas desulfurization synergist, which can ens...
