Description

Technical Field

[0001] The present application relates to the field of resource utilization applications, and in particular to a resource-based heat treatment device for organic materials. Background Art

[0002] Heat treatment is a commonly used pretreatment method for organic materials. The traditional heating method is to directly introduce steam into the heating device for heating, so as to perform high-temperature sterilization and decompose organic substances. And in the traditional organic material pretreatment workshop, there is a hot water tank to provide the hot water required for production in the pretreatment workshop, such as for equipment backwashing, rinsing and floor flushing. The hot water tank also uses steam to heat industrial cold water.

[0003] In the above process of treating organic materials, steam needs to be led to the heating device and the hot water tank respectively. However, in the process of heating organic substances or industrial cold water with steam, the energy consumption is relatively high, and the heating device is prone to scaling, the heat transfer efficiency is low, and the treatment effect is poor, resulting in waste of steam heat energy; at the same time, a large amount of heat will be dissipated when the heating device and the hot water tank are working, resulting in waste of steam heat energy.

In addition, in the description of the present utility model, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0017] The following is combined with the attached Figure 1-2A further detailed description of the present application is provided.

[0018] A resource heat treatment device for organic materials includes a first heating tank 1, a second heating tank 2, and a hot water tank 3. The first heating tank 1, the second heating tank 2, and the hot water tank 3 are integrated. A baffle 4 is provided between the first heating tank 1 and the second heating tank 2, and a space is left below the baffle 4 so that the first heating tank 1 and the second heating tank 2 communicate.

[0019] The first heating tank 1, the second heating tank 2, and the hot water tank 3 are concentrated into one body in the form of a triple tank. The first heating tank 1 is used to preheat the material to a specified intermediate temperature, thereby preventing the material from being heated rapidly, avoiding scale formation on the tank wall, and thus avoiding affecting the thermal efficiency and subsequent operation. The second heating tank 2 is used to finally heat the material so that the material reaches the final required heating temperature. The heating device is divided into two steps, thereby effectively preventing a large amount of scale from forming on the inner wall of the tank, improving the heat transfer efficiency, and reducing the waste of steam heat. Moreover, the integrated first heating tank 1, second heating tank 2, and hot water tank 3 can mutually utilize the steam heat energy, thereby reducing the steam energy consumption and reducing the heat loss of the three tanks. The integration also helps to save space and floor area, save steam and the pipeline for installing materials, and is convenient for operation and management.

[0020] In one embodiment, a mixing and stirring machine 5 is provided at the top of both the first heating tank 1 and the second heating tank 2.

[0021] In one embodiment, steam channels 6 are provided at the inner bottom of the first heating tank 1, the second heating tank 2, and the hot water tank 3.

[0022] A feed inlet 7 is provided at the top of the first heating tank 1. The material enters the first heating tank 1 through the feed inlet 7, and steam heats the first heating tank 1 through the steam channel 6 of the first heating tank 1. At the same time, the mixing and stirring machine 5 at the top of the first heating tank 1 is started to stir the material in the first heating tank 1 evenly and preheat the material, that is, the material is preheated to a specified intermediate temperature of 35 - 40 °C. The preheated material enters the second heating tank 2 and is heated again. Steam heats the second heating tank 2 through the steam channel 6 of the second heating tank 2. At the same time, the mixing and stirring machine 5 of the second heating tank 2 is started to stir the material in the second heating tank 2 evenly so that the material reaches the final required temperature, that is, 80 - 85 °C.

[0023] The steam channel 6 is annular, and the cross-sectional area of the steam channel 6 is larger than the cross-sectional area of the steam pipe for transporting steam, so that the steam pressure and temperature entering the heating tank are relatively stable, thereby ensuring that the material temperature can rise evenly and slowly. Cooperating with the mixing and stirring machine 5, the phenomenon of excessive local temperature is effectively avoided. Through heating, the oil components in the material are fully released, and at the same time, the effect of sterilizing the material is achieved. At the same time, preheating effectively prevents the material from being heated rapidly and avoids scale formation on the tank wall.

[0024] Due to the complex material composition, especially containing a large amount of scale-forming substances such as organic colloids and mineral colloids, rapid heating within a short period will cause a large amount of scale on the tank wall, affecting the thermal efficiency and subsequent operation. Heating in two steps can effectively prevent a large amount of scale on the tank wall and reduce energy consumption at the same time.

[0025] In one embodiment, a conical shell 8 is provided at the bottom of each of the first heating tank 1, the second heating tank 2, and the hot water tank 3, and a discharge port 9 is provided at the bottom of the conical shell 8.

[0026] In one embodiment, a condensate drain port 10 is provided in the steam channel 6.

[0027] In one embodiment, a tank overflow port 11 is provided on the side wall of the second heating tank 2.

[0028] In one embodiment, temperature transmitters 12 are provided in each of the first heating tank 1, the second heating tank 2, and the hot water tank 3, which are used to detect the temperature inside the tank and are interlocked with the inlet valves of the steam pipes for transporting steam.

[0029] Taking the hot water tank 3 as an example, the temperature transmitter 12 provided in the hot water tank 3 is associated with the automatic valve at the inlet of the steam pipe for transporting steam in the hot water tank 3. When the water temperature in the hot water tank 3 reaches a certain temperature, the valve on the steam pipe will automatically close, and the heating inside the tank will stop to avoid excessive consumption of heat energy. When the water temperature drops, the valve will automatically start to heat the water temperature again to ensure that the water temperature in the hot water tank 3 is within a constant range, which helps to maintain the normal operation and safe use of the hot water tank 3. Combining the hot water tank 3 with the material heating tank helps to reduce heat energy loss and improve the thermal efficiency of the device.

[0030] During the actual use of the device of the present application, on the one hand, it can effectively sterilize the material, and on the other hand, it can hydrolyze macromolecular organic matter into small molecular organic matter that is easy to be decomposed by microorganisms, which can improve the biogas production rate and gas production rate of the subsequent anaerobic process. At the same time, the device of the present application can separate the solid-phase grease in the material, greatly improving the waste oil recovery efficiency, bringing good economic benefits, and also avoiding the adverse effects of grease on the subsequent anaerobic process. After the material is processed by the device of the present application, the natural separation of oil, water, and slag can be realized. The grease can be recovered, the water can be made into biogas energy through the subsequent anaerobic process, and the slag can be made into organic fertilizer for utilization, thereby improving the efficiency of resource utilization of organic materials.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
