The application is described in further detail below with reference to fig. 1-2.

The utility model provides a resourceful heat treatment device of organic material, includes first heating jar 1, second heating jar 2 and hot water tank 3, and first heating jar 1, second heating jar 2 and hot water tank 3 are the integral type, are equipped with baffle 4 between first heating jar 1 and the second heating jar 2, and the space is left to baffle 4 below makes first heating jar 1 and second heating jar 2 intercommunication.

The first heating tank 1, the second heating tank 2 and the hot water tank 3 are integrated into a whole in a triple tank mode. The first heating tank 1 is used for preheating materials to a specified intermediate temperature, so that the materials are prevented from being rapidly heated, scaling of the tank wall is avoided, and the influence on the heat efficiency and the follow-up operation is avoided. The second heating tank 2 is used for final heating of the material so that the material reaches the final desired heating temperature. The heating device is divided into two steps, so that a large amount of scaling on the inner wall of the tank body is effectively prevented, the heat transfer efficiency is improved, and the waste of steam heat is reduced. And three jars of integral type first heating jar 1, second heating jar 2 and hot water jar 3 can the mutual steam heat energy to reduce steam energy consumption, reduce the heat loss of three jar bodies. The integrated type is also beneficial to saving space and occupied area, saving steam and material installation pipelines and convenient operation and management.

In one embodiment, the first heating tank 1 and the second heating tank 2 are each provided with a mixer 5 at the top.

In one embodiment, the inner bottoms of the first heating tank 1, the second heating tank 2 and the hot water tank 3 are each provided with a steam channel 6.

The top of the first heating tank 1 is provided with a feed inlet 7. The material enters the first heating tank 1 through the feed inlet 7, and the steam heats the first heating tank 1 through the steam channel 6 of the first heating tank 1. Simultaneously, the mixing stirrer 5 at the top of the first heating tank 1 is started to stir the materials in the first heating tank 1 uniformly, and the materials are preheated, namely, the materials are preheated to a designated intermediate temperature of 35-40 ℃. The preheated materials enter the second heating tank 2 and are heated again, steam heats the second heating tank 2 through the steam channel 6 of the second heating tank 2, and meanwhile, the mixing stirrer 5 of the second heating tank 2 is started to uniformly stir the materials in the second heating tank 2, so that the materials reach the final required temperature, namely 80-85 ℃.

The steam channel 6 is annular, and the sectional area of the steam channel 6 is larger than the sectional area of a steam pipeline for conveying steam, so that the steam pressure and the steam temperature entering the heating tank are relatively stable, the material temperature can be ensured to be uniformly and slowly increased, and the phenomenon of overhigh local temperature is effectively avoided by matching with the mixing stirrer 5. The grease component in the material is fully released by heating, and meanwhile, the effect of sterilizing the material is achieved. Meanwhile, preheating effectively prevents materials from being rapidly heated, and scaling of the tank wall is avoided.

Because the material composition is complicated, especially contains a large amount of scale-prone substances, such as organic colloid, mineral colloid and the like, rapid heating in a short time can cause a large amount of scale formation on the tank wall, and the thermal efficiency and the subsequent operation are affected. The heating is performed in two steps, so that a large amount of scaling of the tank wall can be effectively prevented, and the energy consumption is reduced.

Taking the hot water tank 3 as an example, a temperature transmitter 12 arranged in the hot water tank 3 is controlled in association with an automatic valve of a steam pipeline inlet of the hot water tank 3 for conveying steam. When the water temperature in the hot water tank 3 reaches a certain temperature, the valve on the steam pipeline can be automatically closed, and the temperature in the tank is stopped to avoid excessive consumption of heat energy, when the water temperature is reduced, the valve is automatically started to heat the water again, the constant water temperature range of the hot water tank 3 is ensured, and the normal operation and the safe use of the hot water tank 3 are facilitated to be maintained. The hot water tank 3 and the material heating tank are combined together, so that the heat energy loss is reduced, and the heat efficiency of the device is improved.

In the actual use process of the device, on one hand, the device can effectively sterilize materials, and on the other hand, macromolecular organic matters can be hydrolyzed into micromolecular organic matters which are easy to be decomposed by microorganisms, so that the biogas yield and the biogas production rate of the subsequent anaerobic process can be improved. Meanwhile, the device can separate solid-phase grease in the materials, greatly improves the waste oil recovery efficiency, brings good economic benefit, and avoids the adverse effect of grease on the subsequent anaerobic process. After the materials are treated by the device, the natural separation of oil, water and slag can be realized, the oil and the slag can be recovered, the water can be prepared into biogas energy through a subsequent anaerobic process, and the slag can be prepared into organic fertilizer for use, so that the recycling efficiency of the organic materials is improved.
