Description

Uniform scattering device of decomposing furnace

Technical Field

The utility model relates to a cement manufacture equipment technical field, in particular to decomposing furnace evenly spills material device.

Background

The decomposing furnace is a novel thermal equipment for simultaneously carrying out fuel combustion, heat exchange and decomposition reaction, and has various types and forms. The basic principle is that preheated raw meal, a certain amount of fuel and a proper amount of hot gas are fed into a decomposing furnace at the same time, and the raw meal is in a suspension or boiling state in the furnace; the fuel is subjected to flameless combustion at the temperature below 900 ℃, and the heat transfer and the carbon strand calcium decomposition process are completed at high speed: the combustion time of the fuel and the time required for decomposing the calcium carbonate are about 2-4s, the decomposition rate of the calcium carbonate in the raw material can reach 85-95 percent, and the temperature of the preheated raw material is 800-850 ℃. Solid, liquid or gas fuel can be used in the decomposing furnace, coal powder is mainly used as fuel in China, and the fuel added into the decomposing furnace accounts for about 55-65% of the total fuel.

In a typical decomposing furnace with a precombustion chamber, raw meal entering the decomposing furnace falls into the decomposing furnace from the top of the precombustion chamber through a discharge pipe of a cyclone. After falling into the pre-combustion chamber, the raw materials are generally blown away by tertiary air entering the pre-combustion chamber so as to be in full contact with high-temperature flue gas in the furnace to perform efficient heat exchange. However, it is difficult to uniformly disperse the raw meal due to the adhesion between particles of the raw meal when the raw meal enters the decomposing furnace, and the unevenness of the raw meal when it is discharged. Especially when the blanking is not uniform, a large strand of raw materials can directly and rapidly fall to the bottom of the decomposing furnace along with hot air flow from the tertiary air duct. And the raw material is not fully contacted with the high-temperature flue gas, so that due heat exchange is not carried out on the raw material, the temperature of the raw material is not raised to the decomposition temperature of calcium carbonate, and the decomposition rate does not meet the specified requirement. Affecting the capacity of the decomposing furnace. Meanwhile, the flue gas does not exchange heat with the raw meal, so that heat is wasted.
