Embodiment Construction

[0008] The energy-saving sulfur-fixing agent of the present invention is made of the following raw materials in weight ratio: 10-25 parts of potassium permanganate, 2-10 parts of ferric oxide, 5-15 parts of potassium nitrate, 1-25 parts of potassium hydroxide 10 parts, 5-10 parts of barium nitrate, 1-10 parts of calcium oxide, 10-20 parts of manganese dioxide, 1-5 parts of copper oxide, 20-30 parts of sodium chloride, 60-80 parts of Yuanming powder, the above raw materials After thorough mixing, seal the package. These substances can release atomic oxygen during the reaction process, and atomic oxygen can directly react with carbon to release heat. Its reaction formula is:

[0009] MO 3 →MO+2[O];

[0010] 2[O]+C→CO 2 —94.1×4.184kJ / mol.

[0011] Atomic oxygen can react exothermicly with carbon, because there is no process of endothermic dissociation of oxygen molecules in the reaction process (O 2 →O+O+96×4.184kJ / mol), so it is far higher than the heat energy released by ...

Abstract

The invention discloses an energy-saving sulfur-fixing agent, solving the problem of the prior art that a great deal of harmful gas such as sulfur dioxide and the like is released during the combustion process of coal to cause pollution to the environment. The energy-saving sulfur-fixing agent reserves sulfur in the coal as a solid compound. The energy-saving sulfur-fixing agent is made from the following raw materials by weight proportion: 10 to 25 portions of potassium permanganate, 2 to 10 portions of ferric oxide, 5 to 15 portions of potassium nitrate, 1 to 10 portions of potassium hydroxide, 5 to 10 portions of barium nitrate, 1 to 10 portions of calcium oxide, 10 to 20 portions of manganese dioxide, 1 to 5 portions of copper oxide, 20 to 30 portions of sodium chloride and 60 to 80 portions of glauber slat. The raw materials are mixed completely and are closed and packed. The energy-saving sulfur-fixing agent has the beneficial effects of promoting sufficient burning and improving combustion efficiency, has good sulfur-fixing effect and can reduce more than 80 percent of the discharge amount of sulfur dioxide during the combustion process of the coal.

Description

technical field [0001] The invention relates to an energy-saving sulfur-fixing agent, which is a mixed additive used for reducing the discharge of harmful gases such as sulfur dioxide in the coal combustion process. Background technique [0002] As we all know, during the combustion process of coal, a large amount of sulfur dioxide gas will be emitted into the atmosphere, causing serious pollution to the environment. Adding a sulfur-fixing agent during the combustion of coal to react the released gaseous sulfur dioxide with the compound in the sulfur-fixing agent to form solid sulfide, thereby reducing the emission of sulfur dioxide gas, is a simple and easy method, which is widely used . However, due to complex chemical reactions and other reactions generated under high temperature conditions, the sulfur-fixing effect of the sulfur-fixing agents commonly used in the prior art is generally not ideal. Based on the above problems, the present invention provides an energy-sav...
