technical field

The invention relates to the technical field of hydrothermal carbonization, in particular to a hydrothermal carbonization integrated process equipment.

Background technique

Biomass in a broad sense refers to all organic substances that can grow. Biomass wastes can be recycled by hydrothermal carbonization and prepared into hydrothermal carbon with high energy density to be used as fuel. However, there are many types of biomass waste products, and the physical properties of biomass between different types are also quite different. For example, agricultural plant biomass usually includes straw and livestock manure, with high carbon content and low water content, and is in a solid state; domestic and meal waste, with high water content, is in a state of liquid or a mixture of solid and liquid; Sludge garbage usually contains a certain amount of microorganisms, has a high viscosity, and is in a state of solid-liquid mixing.

In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified and limited, the term "connected" should be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

It is understood that the devices are multifunctional regardless of their orientation in space.

During hydrothermal carbonization, it is usually necessary to crush and ferment the biomass. The crusher 1 is used for crushing, and the fermentation tank is used for fermentation. However, in order to ensure that the crushed materials can fully undergo the hydrothermal carbonization reaction, the feed port of the fermentation tank is usually set at the top, and the discharge port is set at the bottom to make full use of the effect of gravity. Biomass usually includes agricultural and forestry waste biomass, livestock manure, kitchen waste, etc., so it is usually in a solid-liquid mixed state with a solid content of more than 30%, and has a certain fluidity, but it cannot be regarded as a liquid. For this type of biomass, the existing treatment methods include two: first, the crusher 1 is set at a high place, and the fermenter is set at a low place, so that the crushed biomass can be directly transported to the fermenter through the pipeline; Second, since the lifting of the solid-liquid mixed biomass cannot be realized at the same time, the biomass can only be separated from the solid and liquid first, and then the corresponding crusher 1 and the fermenter at the same level are used separately to separate the solid biomass into water. Thermal carbonization and hydrothermal carbonization of liquid biomass.

Both of these two methods have obvious defects: the first one takes up a lot of height space, either a special high platform needs to be set up to install the crusher 1, or a special deep pit needs to be set up to install the fermentation tank, and the complex structure is not conducive to The setting of the whole system; the second type, because two sets of equipment are required for hydrothermal carbonization respectively, more space and resources are required. In addition, the reaction rate of the existing equipment is relatively low during the hydrothermal carbonization reaction, and a large amount of biomass is still mixed in the reaction product, which affects the use of hydrothermal carbon and reduces the energy density and energy density of hydrothermal carbon. energy utilization.

The added water, and the material to be reacted obtained after mixing and stirring are first pre-fermented in the fermentation tank 2, so that more tiny bubbles are generated in the interior due to the fermentation process, and then transported to the high-pressure reactor 3 through the second conveying channel Hydrothermal carbonization can make the reaction more sufficient.
