Technical Field

The invention relates to a heat accumulating type slag dry type granulator.

Background

The temperature of the slag discharged in the metal and alloy smelting process of blast furnaces, submerged arc furnaces, dtex furnaces and the like is up to 1450-1600 ℃, the slag contains larger enthalpy, and main elements in the slag are calcium, silicon and other metal elements which are basically similar to the element proportion of cement clinker, so that the slag can be properly treated and can be used as the cement clinker, and the slag has better economic value.

If the slag is used as a cement additive, the key point is to control the phase change time of the slag, so that the slag cannot react to generate a stable compound in the phase change process, and the chemical activity is reserved in a vitreous state.

Therefore, most of the slag is rapidly cooled by adopting a water quenching mode, and the chemical activity is kept to be used as a cement additive; however, the water quenching process causes high-grade heat energy to be converted into hot water, and water vapor is discharged into the atmosphere, so that not only is energy wasted, but also the existing operating environment is deteriorated; and the water granulated slag also needs energy drying when in use; therefore, the dry-process research of the slag is also proposed earlier and continues for many years, and the dry-process research also continues to be carried out continuously for many years, but each process has a series of problems of high energy consumption, small scale, unsuitability for industrial application and the like.

The heat accumulating type dry slag granulator utilizes a heat accumulating ball heat accumulating mode, effectively solves the defects of energy consumption, industrial amplification and the like, and can configure the granulator scale according to the slag production to realize dry quenching of the slag.

Detailed Description

The invention is explained in further detail below with reference to the drawings.

See fig. 1.

A heat accumulating type slag dry type granulator comprises a chain grate 1 and a motor 2; the chain grate 1 is driven by a motor 2; a slag inlet 3 and a heat storage ball inlet 4 are arranged above the chain grate 1; the heat storage ball inlet 4 is also positioned above the chain grate 1; and the chain grate 1 is also provided with a ball distributor 5 for distributing heat storage balls.

Specifically, the ball distributor 5 is located at the starting end of the traveling grate 1.

Specifically, the bottom of the traveling grate 1 is provided with a slag scraper 6.

Specifically, heat accumulation ball storehouse is connected to heat accumulation ball entry 4, and the heat accumulation ball is stored in the heat accumulation ball storehouse, and the heat accumulation ball in the heat accumulation ball storehouse passes through heat accumulation ball entry 4 and drops to chain grate 1 on.

Principle of use and description thereof: the invention uses the traveling grate 1 as a bearing body, uses an external motor 2 to drive the traveling grate 1 to operate, bears the mixture of slag and heat storage spheres, completes the rapid cooling of the slag by mixing the heat storage spheres and the slag, and completes the dry granulation of the slag on the basis of keeping the chemical activity; the start end of the traveling grate 1 is provided with a ball distributor 5 for distributing heat storage balls, and a layer of heat storage balls is laid on the traveling grate 1 through the ball distributor 5 to prevent molten slag from directly falling on the traveling grate 1; a slag inlet 3 and a heat storage ball inlet 4 are arranged above the chain grate 1, slag flows in from the slag inlet 3, heat storage balls fall from the heat storage ball inlet 4 at the upper part of the slag inlet 3, the heat storage balls are directly mixed with the slag, and the number of the heat storage balls is set according to the amount of the slag; the slag and the heat storage balls are mixed and stacked on the chain grate 1, the thickness of the stack is controlled by the running speed of the chain grate 1 (the running speed is controlled by the motor 2), the slag and the heat storage balls finish heat transfer on the chain grate 1, so that the heat energy of the slag is transferred to the heat storage balls, the temperature is rapidly reduced to the temperature at which no chemical reaction exists, the slag exists in a glass state, and the chemical activity of the slag is retained. The length of the chain grate 1 is defined mainly according to the slag discharge time, the discharge amount and the heat transfer time, so that the dry granulation of the slag is completed at one time in the slag discharge process; the slag scraper 6 is arranged below the traveling grate 1, and when the mixed material is discharged and the traveling grate 1 runs to the lower part, the slag scraper 6 acts to remove the fixed slag on the traveling grate 1.
