Production process combining waste heat boiler with roller compound fertilizer drying furnace

Abstract

The invention provides a production process combining a waste heat boiler with a roller compound fertilizer drying furnace and relates to the technical field of compound fertilizer production processes. The production process comprises the steps of design and model selection of a waste heat boiler, combination of the waste heat boiler and a compound fertilizer production system drying furnace and operation combination of a hot blast stove and the waste heat boiler. By using the production technology combining the waste heat boiler and the roller compound fertilizer drying furnace, self-sufficiency of steam of a production line under the condition that the basic production technology is met is achieved; and by combining with an existing production line, compared with an originally separate steam boiler, the labor cost is reduced, the heat utilization rate is increased, the problem of construction of steam boilers in areas with high environmental protection requirements is solved, and the limitation of steam supply on production development of enterprises is eliminated.

Description

technical field [0001] The invention provides a production process combining a waste heat boiler and a drum compound fertilizer drying furnace, and relates to the technical field of compound fertilizer production process. Background technique [0002] Steam is an important production condition in the production of drum compound fertilizer. In addition to providing the liquid phase for powdery materials to granulate, it can also bring part of the heat to the system, which is conducive to the improvement of production capacity and quality. Therefore, most of the compound fertilizer Enterprises are equipped with steam boilers and a sufficient number of professionals are responsible for operation and management. The steam generated by the steam boilers is transported into the use workshop through long-distance pipelines, and distributed to each steam section after being buffered by the sub-cylinders of the workshop. The main thing is the granulation section, so many companies ne...

[0002] Steam is an important production condition in the production of drum compound fertilizer. In addition to providing the liquid phase for powdery materials to granulate, it can also bring part of the heat to the system, which is conducive to the improvement of production capacity and quality. Therefore, most of the compound fertilizer Enterprises are equipped with steam boilers and a sufficient number of professionals are responsible for operation and management. The steam generated by the steam boilers is transported into the use workshop through long-distance pipelines, and distributed to each steam section after being buffered by the sub-cylinders of the workshop. The main thing is the granulation section, so many companies need to be equipped with steam boilers or purchased steam from power plants. However, with the upgrading of national environmental protection requirements, traditional coal-fired steam boilers are basically banned, and steam boilers with other fuel forms are mostly difficult to approve. Purchasing steam not only needs to spend a lot of construction funds, but also is often affected by the inspection and maintenance of the steam supply unit and the heating season
