The color masterbatch itself has very outstanding performance, which is why it can be widely used in the actual product production field. In the field of actual production of color masterbatch products, general manufacturers tend to carry out air preheating in advance, and only after the actual air heat reaches a certain requirement, the manufacturer will proceed with product production. Why is this?

Generally speaking, manufacturers use air preheating in the production of masterbatches to reduce the fuel consumption of the reactor, reduce the amount of secondary emergency cooling water and the amount of tail gas, and increase the heat value of the tail gas. When the air preheating temperature is increased by 100℃, it can reduce the total energy consumption by 1.95%, therefore, increasing the air preheating temperature is an important measure to save energy in masterbatch production.

However, if the air preheating temperature is higher, then the structure, material and production operation and control requirements of the air preheater are also higher, and the cost is also higher. Currently, foreign countries are promoting the application of 800 ℃ level air preheater, 900 ℃ level air preheater has begun to put into industrial operation, 1000 ℃ level air preheater is in the design and manufacturing stage.

In the production of products, the use of high-temperature air preheater with the use of medium-temperature air preheater comparison, fuel savings of 8.48%, an increase in output of 5.60%. In addition, the use of an emergency cooling boiler before the air preheater to replace all or part of the emergency cooling water can significantly reduce the amount of emergency cooling water and tail gas, thereby further reducing energy consumption and increasing production capacity.

In order to further save energy, the manufacturers are also actively improving the pre-heating technology of masterbatches, passing the tail gas through the water washing tower to remove most of the water vapor in the tail gas and improve the calorific value of the tail gas, so that they can use the gas turbine with high thermal efficiency to generate electricity, and also remove the sulfur and dust in the tail gas, receiving the dual effect of energy saving and environmental protection.

To sum up: manufacturers in the production process of masterbatches for air preheating, mainly to reduce energy consumption, energy saving, so that not only can improve production efficiency, but also to a certain extent to reduce the production process to bring pollution to the environment.
