Abstract
The invention discloses a yellow tobacco treatment easy preparation and a preparation method thereof, wherein every 100 kg of sodium sulfide is dissolved in 200L of water, then sodium hydroxide is added, the dosage of the sodium hydroxide is such that the pH value of the solution is 11.8-12.2, and the yellow tobacco treatment easy preparation is obtained.
Description
Technical Field
The invention relates to the technical field of waste gas treatment, in particular to a yellow tobacco treatment easy-to-prepare method and a preparation method thereof.
Background
The stripping is an indispensable procedure in the electroplating process, most electroplating enterprises adopt the stripping process of taking nitrate as an oxidant at present, and the oxidability of nitrate ions is utilized to dissolve and strip the metal on the plated part, thereby achieving the purpose of stripping the plating layer. When the metal is oxidized to metal ions into solution, nitrate ions are reduced to form NO and N02The gas is discharged into the air to form yellow smoke, which is commonly called yellow smoke. Yellow smoke has direct harm to the health of operators who strip the plating, and more importantly, the high-concentration nitrogen oxide entering the air can cause a series of more extensive harm, such as ozone layer destruction, acid rain formation, dust adhesion and human body respiratory tract entering. Therefore, it is necessary to effectively control the generation of yellow smoke during the deplating process.
The traditional yellow smoke treatment method adopts an air draft tower for spraying and sodium hydroxide is added for treatment, and the method has poor yellow smoke treatment effect and cannot meet the environmental protection requirement, particularly cannot treat yellow smoke with high nitrogen dioxide concentration.
Disclosure of Invention
The invention aims to provide a yellow tobacco treatment easy preparation capable of effectively absorbing yellow tobacco and a preparation method thereof.
In order to achieve the purpose, the invention adopts the technical scheme that:
a preparation method of a yellow tobacco treatment easy preparation comprises the following steps: dissolving every 100 kg of sodium sulfide in 200L of water, and then adding sodium hydroxide, wherein the amount of the sodium hydroxide is such that the pH value of the solution is 11.8-12.2, thus obtaining the yellow tobacco treatment easy preparation.
The application method of the yellow tobacco treatment easy preparation provided by the invention comprises the following steps: collecting yellow smoke generated by deplating into a spray tower, adding a yellow smoke treatment easy preparation into a spray groove of the spray tower, pumping the yellow smoke treatment easy preparation in the spray groove into the spray tower through a water pump, absorbing the yellow smoke by utilizing the sprayed yellow smoke treatment easy preparation, adding the yellow smoke treatment easy preparation for 4 times in a treatment period of one week, adding the yellow smoke treatment easy preparation containing 100 kg of sodium sulfide for the first time, and adding the yellow smoke treatment easy preparation containing 4-6 kg of sodium sulfide for the other three times respectively.
Preferably, in a treatment period of one week, the yellow tobacco treatment easy preparation is added for 4 times on the first day, the third day, the fifth day and the seventh day, the yellow tobacco treatment easy preparation containing 100 kg of sodium sulfide is added for the first time, and the yellow tobacco treatment easy preparation containing 5 kg of sodium sulfide is added for the other three times.
In the prior art, the effect of treating yellow smoke by only adopting sodium hydroxide is not ideal, particularly yellow smoke with high nitrogen dioxide concentration cannot be treated, and when the yellow smoke is treated by only adopting sodium sulfide, the sodium sulfide is easy to generate nitrate precipitate in the use process, so that the nozzle of a spray tower is blocked, and the treatment effect is reduced. By adopting the technical scheme, the yellow smoke treatment easy preparation is prepared from sodium sulfide and sodium hydroxide, the pH value is 11.8-12.0, the yellow smoke generated by nitric acid can be completely removed, the phenomenon of nozzle blockage is avoided, and the environment-friendly requirement is met. The yellow tobacco treatment easy preparation is simple in preparation method, high in yellow tobacco removal efficiency and suitable for popularization and application.
