Problems solved by technology

The solid particle smoke that can be suspended in the gas not only pollutes the environment, but also causes certain harm to the inhaler. If it is not suppressed and directly discharged into the environment, the damage to the environment is immeasurable

preparation example Construction

[0032] The present invention provides a preparation method for the smoke inhibitor described in the above technical scheme, comprising the following steps:

[0033] mixing a phosphoric acid compound with a carbonic acid compound to obtain a mixture;

[0034] The mixture is mixed with aluminosilicate and chloride to obtain a smoke suppressant.

[0035] The invention mixes the phosphoric acid compound and the carbonic acid compound to obtain the mixture. In the present invention, there is no special limitation on the operation of mixing the phosphoric acid compound and the carbonic acid compound, and the technical solution for preparing the mixed material well known to those skilled in the art can be adopted.

[0036] In the present invention, the mixing of the phosphoric acid compound and the carbonic acid compound is preferably carried out under the condition of stirring. In the present invention, the stirring rate is preferably 200-300 r / min, more preferably 250-300 r / min; ...

Embodiment 1

[0043] Raw materials: 50% bentonite, 20% sodium phosphate, 15% potassium carbonate, 15% potassium chloride;

[0044] First add sodium phosphate and potassium carbonate to the mixer, stir at a speed of 300r / min for 15 minutes to obtain a mixture, then add the mixture, potassium chloride and bentonite to a grinder, and grind for 12 hours under vacuum to obtain a smoke inhibitor.

Embodiment 2

[0046] Raw materials: montmorillonite 52%, ammonium phosphate 21%, potassium carbonate 13%, sodium chloride 14%;

[0047] Adopt the same preparation method as Example 1.

Abstract

The invention provides a smoke dust inhibitor which comprises the following components in percentage by mass: 46-54% of aluminosilicate, 19-22% of a phosphoric acid compound, 13-17% of a carbonic acid compound and 13-17% of chloride. The smoke dust inhibitor is prepared by taking aluminosilicate, a phosphoric acid compound, a carbonic acid compound and chloride as raw materials, and the dosage of each component is controlled, so that iron oxide in the smoke dust can be completely decomposed, nitrogen oxide can be completely volatilized, and the floating of graphite can be prevented, thereby realizing the effective inhibition on the smoke dust. Results of the embodiment show that the smoke dust inhibitor provided by the invention has the smoke dust covering performance of 100%, the flame retardant performance of 100%, the floating prevention performance of 100% and the decomposition performance of 100%.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a smoke inhibitor and its preparation method and application. Background technique [0002] In recent years, the iron and steel industry has developed rapidly, and the pollution to the environment has become more and more serious. The environmental problems caused by the metallurgical industry have also attracted people's attention. Modern iron and steel metallurgy often adopts the method of pyrometallurgy to smelt iron and steel. Pyrometallurgy is a smelting process for extracting or refining metals in high-temperature metallurgy. It is the application of physical and chemical principles in high-temperature chemical reactions. Pyrometallurgy generally includes three major processes: raw material preparation, smelting and blowing, and refining. In addition to metals or metal compounds, the products in the process include slag, flue gas and smoke. [0003] Among them, the ma...
