Description

Technical Field

[0001] The utility model relates to the technical field of gas agitators, in particular to an energy-saving gas agitator. Background Art

[0002] The crude synthesis gas produced by the gasifier of coal chemical industry contains acidic gases such as HCl and HF, as well as trace solids such as a small amount of fly ash. At this time, alkali liquid needs to be mixed with the crude synthesis gas to remove acidic gases such as HCl and HF in the crude synthesis gas. Generally, alkali liquid with 20% sodium hydroxide is used. The concentration of the purchased pure sodium hydroxide solution is large and cannot be added directly, but needs to be diluted. Pure sodium hydroxide is oily and viscous. Although it is easily soluble in water, the alkali liquid will sink to the bottom of the container without stirring, resulting in a high concentration at the bottom of the container and a low concentration at the top. As a result, the efficiency of removing acidic gases with alkali liquid is greatly reduced. Especially in industrial applications, the frequency conversion and pump stroke of the alkali pump must be continuously adjusted according to the pH value of the washing liquid, which increases the control difficulty and the workload. Therefore, a gas agitator is proposed to solve the above-mentioned problems.

The above-mentioned gas agitator has shortcomings. Although the device can achieve gas stirring, it has limitations. The structure is complex, there are many parts, the production cost is high, and it is not conducive to later maintenance, which increases the complexity of use. Secondly, the gas easily adheres to the inner wall of the mixing barrel, which easily causes uneven mixing and waste of gas.

[0004] Therefore, in order to solve such problems, we propose an energy-saving gas agitator. Utility Model Content
