I. Overview
The smoke purification unit is a micro-powder production equipment with internationally advanced level, developed by our company based on the absorption of foreign advanced micronization technology. Compared with the crushers currently used in China, this machine leads in all performance indicators, being a pioneering domestic innovation, meticulously researched and developed by an excellent team. Specifically for sodium bicarbonate material, it can grind the smoke purification material to a rice-sized particle size, being the only fully automatic smoke purification unit with superior performance and high efficiency in energy-saving. Proven by numerous users domestically and internationally, the equipment excels in performance, enhancing product grade and added value, with significant economic benefits. The product's main performance indicators meet the level of similar foreign equipment, can replace imports, and resolves the issues of operation, cycle, and capital for enterprises.
Sodium bicarbonate (baking soda)喷射器 for flue gas desulfurization operates on the fundamental principle of...
Sodium bicarbonate (baking soda, NaHCO3) can be used as an adsorbent for flue gas desulfurization. It removes acidic pollutants from flue gas through chemical adsorption, and also removes some inorganic and organic trace substances through physical adsorption. This process involves directly spraying finely ground sodium bicarbonate into high-temperature flue gas. Under high temperatures, sodium bicarbonate decomposes into sodium carbonate (Na2CO3), water (H2O), and carbon dioxide (CO2).
The newly produced sodium carbonate (Na2CO3) exhibits a high reactivity upon formation, spontaneously reacting with acidic pollutants in flue gas as follows:
Generally, the flue gas temperature ranges between 140 and 250 °C. Due to the high activity of the sodium bicarbonate adsorbent, a slightly excessive amount of sodium bicarbonate (chemical factor between 1.1 and 1.3) is usually sufficient.
Sodium carbonate (soda, Na2CO3) can also be used in flue gas desulfurization, albeit with slightly lower reactivity, but the process flow remains largely unchanged.
II. Usage and Features
This machine is suitable for coal-fired power plants, waste or alternative fuel incineration plants, and can also be widely used in industrial furnaces for glass, cement, metallurgy, and other industries. Dry flue gas purification can economically meet flue gas emission standards and is used for solving flue gas pollution.
The features of this machine are as follows:
1. This is a vertical-axle crushing-type grinder that can simultaneously perform two processing steps: micro-pulverization and micro-powder sorting. 2. Utilizing the principle of air suction flow and a stepless speed regulator with grading impellers, the fineness of the product can be controlled without stopping the machine, and all the fine powder can be recycled, ensuring environmental protection. The machine features wind cooling, resulting in low temperature rise during grinding and uniform particle size of the product. 3. The lifting system combines the transmission principle with an automated system to achieve complete无人automation, energy-saving, safety, and pollution-free operation, while also conserving human resources.
4. Automatic cutting upon material loading, achieving a fully automated, unattended state.
The dust generated during the cutting of the 5 filtration system is automatically吸入 by the filter for purification. The recycled materials from the filter are then circulated back to the storage room, completely resolving the pollution issue.
6. Easy maintenance, operation, and cleaning with high production capacity.
7. This machine utilizes a new narrow triangle belt drive mechanism, featuring high transmission power, stable operation, and high efficiency.
