Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production, in particular to steam generating equipment for compound fertilizer production. Background Art

[0002] Compound fertilizer is a fertilizer made by chemical or mixed methods that contains any two or three of the crop nutrient elements nitrogen, phosphorus and potassium. The production of compound fertilizer is a complex process, which requires the use of steam generating equipment. Steam generators, also called steam heat source machines, are mechanical equipment that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam.

[0003] For example, a steam generating device for compound fertilizer production with publication number CN215863299U has a second spring whose elasticity makes the second piston have a buffering effect. When the medium pressure is large, the medium will push the second piston upward until the second pressure relief hole leaks out, and the pressure can be released through the second pressure relief hole. When the medium pressure is too large, the second piston pushed by the medium can continue to push the first piston until the first pressure relief hole leaks out, and the pressure can be released through the first pressure relief hole, achieving a dual-stage discharge effect. However, the excess heat is directly discharged, resulting in energy waste and insufficient energy saving. For this reason, a steam generating device for compound fertilizer production is proposed for improvement. Utility Model Content
