The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the invention serve to explain the principles of the invention and not to limit its scope.
In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly stated or limited, the term "connected" should be interpreted broadly, and may be, for example, a fixed connection, a detachable connection, or an integral connection, which may be a mechanical connection, an electrical connection, which may be a direct connection, or an indirect connection via an intermediate medium.

In hydrothermal carbonization, it is generally necessary to crush and ferment biomass using the crusher 1 and a fermentation tank. However, in order to ensure that the crushed material can be subjected to hydrothermal carbonization reaction sufficiently, the feed inlet of the fermentation tank is usually arranged at the top, and the discharge outlet is arranged at the bottom, so as to fully utilize the action of gravity. The biomass generally includes agricultural and forestry waste biomass, livestock manure, kitchen waste and the like, and therefore is generally in a solid-liquid mixed state with a solid content of more than 30%, has certain fluidity, but cannot be regarded as a liquid simply. For such biomass, the existing treatment methods include two types: firstly, the crusher 1 is arranged at a high position, and the fermentation tank is arranged at a low position, so that the crushed biomass can be directly conveyed into the fermentation tank through a pipeline; secondly, because the lifting of the solid-liquid mixed biomass cannot be realized at the same time, only the solid-liquid separation of the biomass is carried out, and then the hydrothermal carbonization of the solid biomass and the hydrothermal carbonization of the liquid biomass are respectively carried out by independently using the devices of the corresponding crusher 1 and the fermentation tank on the same horizontal plane.
Both of these approaches have significant drawbacks: firstly, more height space is occupied, a special high platform is required to be arranged to install the crusher 1, or a special pit is required to be arranged to install the fermentation tank, the structure is complex, and the arrangement of the whole system is not facilitated; secondly, because two sets of equipment are needed to respectively carry out hydrothermal carbonization, more space and resources are needed. In addition, the reaction rate of the existing equipment is relatively low when hydrothermal carbonization reaction is carried out, and a large amount of biomass is still mixed in the product after the reaction, so that the use of the hydrothermal carbon is influenced, and the energy density and the energy utilization rate of the hydrothermal carbon are reduced.
According to the embodiment of the invention, the material lifting device is adopted, and the biomass material mixed with solid and liquid is lifted simultaneously on the premise that the crusher 1 and the fermentation tank are in the same horizontal plane, so that the hydrothermal carbonization of the biomass mixed with solid and liquid is simultaneously carried out by using the same equipment, and the reaction rate of the hydrothermal carbonization is improved by the premixing fermentation process and the optimization of the fermentation tank, so that the comprehensive quality of the prepared hydrothermal carbon is improved.
Specifically, as shown in fig. 1, in the embodiment of the present invention, the hydrothermal carbonization integrated process equipment includes: the crusher 1, the fermentation tank 2 and the high-pressure reaction kettle 3 are positioned on the same mounting plane; the crusher 1 is used for crushing biomass, and a discharge port of the crusher 1 is connected with a first feed port of the fermentation tank 2 through a first conveying channel; the discharge hole of the fermentation tank 2 is connected with the feed inlet of the high-pressure reaction kettle 3 through a second conveying channel; the first conveying channel is provided with at least 1 material lifting mechanism 4; the second delivery passage is provided with a fluid pump. In the embodiment of the invention, a crusher 1 is used for crushing biomass to obtain biomass material in a solid-liquid mixed state, the biomass material in the solid-liquid mixed state is conveyed to a first feeding port of a fermentation tank 2 through a material lifting mechanism 4 of a first conveying channel, the biomass material in the solid-liquid mixed state entering the fermentation tank 2 is mixed with liquid inoculum and water entering a second feeding port of the fermentation tank 2, and pre-fermentation is carried out as required, at the moment, liquid material to be reacted can be obtained, the liquid material to be reacted is conveyed to a high-pressure reaction kettle 3 through a second conveying channel, hydrothermal carbonization reaction is carried out in the high-pressure reaction kettle 3 to prepare hydrothermal carbon with good aperture and a large amount of acidic surface functional groups and organic matters, and the hydrothermal carbon is separated through a solid-liquid separation device at a discharging port of the high-pressure reaction kettle 3.
It should be noted that: if the crushed biomass material is mainly biomass with higher carbon content and lower water content, such as similar crops, the water added into the fermentation tank 2 can be properly added, and the material to be reacted obtained after mixing and stirring is directly conveyed into the high-pressure reaction kettle 3 through the second conveying channel for hydrothermal carbonization; if the broken biomass material is mainly the biomass with high viscosity like sludge, the water added in the fermentation tank 2 can be properly reduced, the material to be reacted obtained after mixing and stirring is firstly pre-fermented in the fermentation tank 2, so that more micro bubbles are generated in the material to be reacted due to the fermentation process, and then the material is conveyed to the high-pressure reaction kettle 3 through the second conveying channel for hydrothermal carbonization, so that the reaction is more sufficient.
The discharge port of the crusher 1 is arranged at the bottom of the crusher 1; the first feed inlet and the second feed inlet of fermentation cylinder 2 set up at the top of fermentation cylinder 2, and the discharge gate setting of fermentation cylinder 2 is in the bottom of fermentation cylinder 2. Because the material lifting mechanism 4 is adopted in the embodiment of the invention, the whole equipment can process the biomass in a solid-liquid mixed state on the premise of ensuring that the crusher 1, the fermentation tank 2 and the high-pressure reaction kettle 3 are arranged on the same plane, and the equipment has simple installation and simple structure; in addition, the embodiment of the invention also realizes the mixing and fermentation of the inoculum through the fermentation tank 2, and improves the reaction rate of hydrothermal carbonization, thereby obtaining a hydrothermal carbon product with good aperture, a large amount of acidic surface functional groups and organic matters, and leading the hydrothermal carbonization product to have higher energy density and energy conversion efficiency.
As shown in fig. 2 to 4, the material lifting mechanism 4 is one of the cores of the embodiment of the present invention, and the material lifting mechanism 4 includes: a square tube frame 9 and 2 half square tube mechanisms; half square tube mechanism includes: a half square tube 7, a rotatable baffle 8 and a motor; the square tube frame 9 can splice the half square tubes 7 of the 2 half square tube mechanisms into a square tube, and the motor is used for driving the half square tubes 7 to slide along the axis direction of the square tube; the half square tube 7 comprises a whole side wall and 2 half side walls, the edge of the half side wall is provided with a sealing sliding chute, the whole side wall is hinged with a rotatable baffle 8, and the rotatable baffle 8 can rotate towards the fluid flowing direction to enable materials to flow in the square tube; the rotatable baffle 8 is a rectangular plate, the length of the short edge of the rotatable baffle 8 is equal to the width of the inner wall of the square tube, and sealing strips are arranged on the edges of the periphery of the rotatable baffle 8; the 2 rotatable baffle plates 8 are arranged in sequence along the material flowing direction and do not interfere with each other when rotating.
For convenience of explanation, as shown in fig. 5 and 6, the 2 half-pipe mechanisms are a first mechanism and a second mechanism, respectively: when the half-direction pipe of the first mechanism moves upwards relative to the half-direction pipe of the second mechanism, the rotatable baffle of the first mechanism is abutted against the inner side of the whole side wall of the half-direction pipe of the second mechanism, the rotatable baffle of the second mechanism rotates upwards under the action of materials and is separated from the inner side of the whole side wall of the half-direction pipe of the first mechanism, and the materials enter between the rotatable baffle of the first mechanism and the rotatable baffle of the second mechanism from the lower part of the rotatable baffle of the second mechanism through the separated opening; when the half-square pipe of the second mechanism moves upwards relative to the half-square pipe of the first mechanism, the rotatable baffle of the second mechanism is abutted against the inner side of the whole side wall of the half-square pipe of the first mechanism, the rotatable baffle of the first mechanism rotates upwards under the action of the materials, and the materials enter the upper part of the rotatable baffle of the first mechanism from the position between the rotatable baffle of the first mechanism and the rotatable baffle of the second mechanism through the separated opening; when the first mechanism and the second mechanism continuously slide up and down relatively, the materials are lifted up gradually from bottom to top. And the sealing strip at the edge of the rotatable baffle can prevent the solid-liquid mixed material from falling back when the rotatable baffle abuts against the whole side wall.
In order to guarantee that 2 half square tube mechanisms can slide relatively, the cross sectional shape of the sealing chute of the first mechanism is in a shape like a Chinese character 'tu', a sealing slide block with a cross sectional shape like a Chinese character 'tu' is arranged at a corresponding position of the second mechanism, the sealing chute and the sealing slide block can perform relative sliding and can also play a role in limiting to prevent the separation of the 2 half square tube mechanisms, and in addition, a sealing strip arranged on a contact surface of the sealing chute and the sealing slide block can prevent materials from leaking from the splicing position of the 2 half square tube mechanisms.
In the embodiment of the invention, the mode of controlling the reciprocating motion of the half square tube 7 by the motor is as follows:

Or, the motor controls the hydraulic cylinder, the cylinder body of the hydraulic cylinder is fixed with the square pipe frame 9, and the piston of the hydraulic cylinder is fixed with the half square pipe 7, so that the reciprocating motion of the half square pipe 7 is realized.
Or, the motor controls the gear-rack pair, the motor is fixed with the square tube frame 9, the output end of the motor is provided with an output gear, the output gear drives the rack gear to rotate through the reduction gear set, so that the rack moves up and down, and the rack is fixed with the half square tube 7, so that the reciprocating motion of the half square tube 7 is realized.
In order to simplify the first conveying channel, a material lifting mechanism 4 is not required to be arranged on the whole first conveying channel, and only a plurality of material lifting mechanisms 4 are required to be arranged to lift solid-liquid mixed materials to a high position. It should be noted that, a square connecting pipe is arranged between the two square connectors, the square connecting pipe can be set as a straight pipe or an elbow pipe according to the situation, and the square connecting pipe should be a rigid pipe to prevent the square connecting pipe from being damaged by the material in the square connecting pipe.
