Pulverized coal activating agent and application thereof
The invention discloses a pulverized coal activator which comprises the following preparation material components: calcium oxide, sodium metasilicate, sodium fluosilicate and sodium tripolyphosphate, the calcium oxide is prepared by heating calcium carbonate, and the sodium metasilicate is mainly prepared by reacting sodium silicate and sodium hydroxide materials. One of the main raw materials of the sodium fluosilicate is fluosilicic acid which is a byproduct in the process of producing anhydrous hydrogen fluoride by taking acid-grade fluorite concentrate powder and sulfuric acid as raw materials, and the sodium tripolyphosphate is mainly prepared from phosphoric acid, sodium hydroxide and water materials. When the pulverized coal activating agent and the application thereof are used for preparing the pulverized coal activating agent, no other impurities are generated, furthermore, when the pulverized coal activating agent is prepared, no nitric oxide is generated, and the pulverized coal activating agent is environment-friendly and can be suitable for industrial production, so that the yield of the actually obtained pulverized coal activating agent is increased; in the whole preparation steps, reaction conditions are mild, easy to reach and control, and the process is stable.
本发明公开了一种煤粉活化剂，包括所述煤粉活化剂的制备材料组分如下：氧化钙、偏硅酸钠、氟硅酸钠和三聚磷酸钠组成，其中氧化钙是通过氧化钙由碳酸钙加热制成，所述偏硅酸钠主要是通过硅酸钠和氢氧化钠材料反应制成，所述氟硅酸钠主要原料之一是以酸级萤石精矿粉和硫酸为原料生产无水氟化氢过程的副产物即氟硅酸，所述三聚磷酸钠主要是通过磷酸、氢氧化钠和水材料制成。该煤粉活化剂及其应用在制备煤粉活化剂时，并不会产生任何其他杂质，进一步的在制备煤粉活化剂时，不会产生氮氧化物，对环境友好，可以适用于产业化生产，实际得到煤粉活化剂的产率提高了，在整个制备步骤中反应条件温和易达到、易于控制，工艺稳定。
