Example Embodiment
[0018] Example 1
[0019] Such as figure 1 As shown, a raw material feeding barrel at a height of 3 meters perpendicular to the chlorine dioxide generator is set outdoors, and a sodium chlorate solution with a concentration of 1-20% is injected into the sodium chlorate feeding barrel 1, and the acid solution feeding barrel 2 Inject a hydrochloric acid solution with a concentration of 1-20%. After heating by the heating rod 3, the hydrochloric acid temperature is controlled at 50°C, and the sodium chlorate temperature is controlled at 80°C. After the impurities are removed by the filter 4, the glass flowmeter 5 controls the sodium chlorate The feed ratio of the aqueous solution and concentrated hydrochloric acid is 1:0.95 by volume. Under the action of gravity, the hydrochloric acid solution and sodium chlorate solution enter the PCV enteric reactor 6 with a tube diameter of 40 mm and a tube length of 3000 mm. High concentration, high purity chlorine dioxide gas. Chlorine dioxid...

[0020] Example 2
[0021] Such as figure 1 As shown, a raw material feeding barrel is set at a height of 4 meters perpendicular to the chlorine dioxide generator, and a sodium chlorite solution with a concentration of 25-30% is injected into the sodium chlorite feeding barrel 1, and the acid feeding barrel Inject a sulfuric acid solution with a concentration of 25-30% into 2 and after heating by heating rod 3, the temperature of sulfuric acid is controlled at 45°C, the temperature of sodium chlorite is controlled at 75°C, and the impurities are removed by filter 4 and controlled by glass flow meter 5. The feed ratio of the sodium chlorite aqueous solution and the concentrated sulfuric acid is 1:1 by volume. Under the action of gravity, the sulfuric acid solution and the sodium chlorite solution enter the titanium-aluminum alloy enteral reactor 6 with a tube diameter of 20 mm and a tube length of 5000 mm, and they are in contact with each other repeatedly while flowing through the...

[0022] Example 3
[0023] Such as figure 1 As shown, a raw material feeding barrel at a height of 5 meters perpendicular to the chlorine dioxide generator is set outdoors, and sodium chlorate solution with a concentration of 32-40% is injected into the sodium chlorate feeding barrel 1, and the acid solution feeding barrel 2 Inject a nitric acid solution with a concentration of 32-40%. After heating by the heating rod 3, the nitric acid temperature is controlled at 60°C, and the sodium chlorite temperature is controlled at 90°C. After the impurities are removed by the filter 4, the glass flow meter 5 controls the chlorine The volume ratio of the feed ratio of sodium aqueous solution and concentrated sulfuric acid is 1:1.05. Under the action of gravity, the sulfuric acid solution and the sodium chlorite solution enter the PTFE enteric reactor 6 with a tube diameter of 50 mm and a tube length of 6000 mm, and they are in contact with each other repeatedly while flowing through the en...
