Further, the working method of the steam sterilization system for the organic fertilizer particles comprises the following steps:

the ethanol supply pipe continuously supplies a predetermined amount of liquid into the pipe of the air outlet cylinder, then the ethanol liquid flows into the air guide channel under the action of gravity, and then the ethanol liquid in the air guide channel flows into the conical annular centrifugal combustion chamber through the air guide gap until the ethanol in the conical annular centrifugal combustion chamber fills one third of the volume of the conical annular centrifugal combustion chamber; then closing a valve on the ethanol supply pipe; the driving device drives the synchronizing wheel through a synchronous driving belt, so that the upper conical thin wall, the lower conical thin wall and the two inclined heating pipes rotate along the axis of the synchronizing wheel; meanwhile, the ethanol liquid in the conical annular centrifugal combustion chamber forms a rotational flow under the rotation drive of the lower conical thin wall, so that the ethanol liquid which flows in the conical annular centrifugal combustion chamber in a rotating manner is uniformly spread on the upper surface of the upper conical thin wall under the action of centrifugal force, and the ethanol liquid level in the conical annular centrifugal combustion chamber is a conical liquid level parallel to the upper conical thin wall;

meanwhile, the soft water supply pipe guides the softened water into the conical water centrifugal gasification chamber through the water outlet end of the water guide pipe, because the rotation of the upper cone thin wall enables the water entering the conical water centrifugal gasification chamber to form rotational flow, the water which rotates and flows in the conical water centrifugal gasification chamber is uniformly spread on the upper surface of the upper cone thin wall under the action of centrifugal force, while the upper cone thin wall in a continuous high temperature state quickly gasifies the water uniformly spread on the upper surface of the upper cone thin wall into hot water vapor with lower temperature relative to the temperature of the ethanol combustion product, finally the high-temperature mixed gas of the carbon dioxide and the water vapor formed after the ethanol is combusted and the hot water vapor with lower temperature generated by the gasification of the water uniformly spread on the upper surface of the upper cone thin wall are converged in the heat flow convergence upwelling channel, forming high-flow hot mixed steam which is gushed upwards and has lower temperature than combustion products but higher temperature than steam generated by direct gasification of water in the heat flow convergence upwelling channel; the converging mechanism can effectively increase the flow of hot steam so as to improve the heating and sterilizing rate of the subsequent organic fertilizer, meanwhile, the highest temperature of the steam is effectively limited through high-temperature and low-temperature steam blending, and the damage degree of the ultrahigh-temperature steam to the nutrient components of the organic fertilizer is avoided while the subsequent sterilizing effect is ensured;

Has the advantages that: after high-temperature mixed gas of carbon dioxide and water vapor formed after final ethanol combustion and hot water vapor with lower relative temperature generated by water gasification uniformly spread on the upper surface of the upper conical thin wall are converged in the heat flow converging upwelling channel, high-flow hot mixed steam with lower temperature than combustion products and higher temperature than steam generated by direct water gasification is formed in the heat flow converging upwelling channel; the converging mechanism can effectively increase the flow of hot steam so as to improve the heating and sterilizing rate of the subsequent organic fertilizer, meanwhile, the highest temperature of the steam is effectively limited through high-temperature and low-temperature steam blending, and the damage degree of the ultrahigh-temperature steam to the nutrient components of the organic fertilizer is avoided while the subsequent sterilizing effect is ensured;

therefore, organic fertilizer particles accumulated in the conical bin after being heated twice continuously stably leak to the upper end position of the machine fertilizer downward sliding slope through the material leaking port, and meanwhile, the organic fertilizer particles leaking from the material leaking port can diffuse outwards under the rotating centrifugal stirring of the centrifugal stirring rod and slide downwards along the downward sliding direction of the machine fertilizer downward sliding slope under the action of gravity, so that the blockage at the material leaking port is avoided; because the two inclined heating pipes follow the rotation along the axis of the synchronous wheel, the material leakage port can also do circumferential rotation motion along the axis of the conical organic fertilizer downward sliding slope, so that the position of the material leakage port is changed constantly, organic fertilizer particles sliding downward on the organic fertilizer downward sliding slope are further uniformly distributed, meanwhile, the organic fertilizer particles sliding downward on the organic fertilizer downward sliding slope are stirred by the rotation of the plurality of sharp particle stirring sheets to be in a continuous rotation rolling state, and at the moment, because the source in the conical ring-shaped organic fertilizer steam sterilization channel continuously flows hot mixed steam with lower temperature than combustion products but higher steam temperature than that generated by the direct gasification of water, the organic fertilizer particles sliding downward on the organic fertilizer downward sliding slope and continuously rotating rolling organic fertilizer particles are fully heated to the sterilization temperature by the high-flow hot mixed steam with lower temperature than the combustion products but higher steam temperature than that generated by the direct gasification of water, thereby achieving the effect of high-efficiency sterilization.

An ignition device is arranged in the conical ring-shaped centrifugal combustion chamber 39.

The working method of the steam sterilization system for the organic fertilizer particles comprises the following steps: the ethanol supply pipe 1 continuously supplies a predetermined amount of liquid into the pipe of the air outlet cylinder 4, then the ethanol liquid flows into the air guide channel 32 under the action of gravity, and then the ethanol liquid in the air guide channel 32 flows into the conical annular centrifugal combustion chamber 39 through the air guide gap 37 until the ethanol in the conical annular centrifugal combustion chamber 39 fills one third of the volume of the conical annular centrifugal combustion chamber 39; then the valve on the ethanol supply pipe 1 is closed; the driving device drives the synchronizing wheel 5 through the synchronous transmission belt 6, so that the upper conical thin wall 40, the lower conical thin wall 42 and the two inclined heating pipes 12 rotate along the axis of the synchronizing wheel 5; meanwhile, the ethanol liquid in the conical annular centrifugal combustion chamber 39 also forms a rotational flow under the rotation driving of the lower conical thin wall 42, so that the ethanol liquid which flows in the conical annular centrifugal combustion chamber 39 in a rotating manner is uniformly spread on the upper surface of the upper conical thin wall 40 under the action of centrifugal force, and the ethanol liquid level in the conical annular centrifugal combustion chamber 39 is a conical liquid level parallel to the upper conical thin wall 40;
