The entire contents of the aforementioned prior applications are incorporated herein by reference.

The invention relates to a hydrothermal carbonization system, a coupling system and application thereof with an energy device, and belongs to the technical field of hydrothermal carbonization treatment.

Biomass includes all plants, microorganisms, and animals that feed on plants, microorganisms, and wastes from the metabolism and/or production of plants, microorganisms, and animals. The wet biomass includes non-edible agricultural products such as food processing waste, industrial organic waste or all organic parts of municipal solid waste.

On the one hand, since wet biomass contains a large amount of water, the water in the wet biomass must be evaporated to remove it in the traditional sense. For example, by three conventional thermochemical reaction processes (torrefaction, pyrolysis or gasification), operating at atmospheric pressure and must operate above the boiling point of water (>100°C), the biomass can be heated to the desired reaction Before the temperature, the moisture in it is removed by evaporation. A typical example is the sludge residue of a water treatment plant, which is first dried before being treated by conventional methods; in addition, some other wet biomass raw materials, such as plant residues that can be used as animal feed, must also rely on drying. save. However, the pre-treatment process of water evaporation and drying not only brings a huge carbon emission load to the industry, but also wastes a lot of water resources; For higher wet biomass raw materials, the pre-process of evaporative drying also loses the energy contained in the biomass itself.

At the same time, the conventional thermochemical treatment of biomass is more suitable for biomass raw materials with low moisture content, such as pure wood biomass, and the conventional thermochemical treatment also easily leads to the loss of carbon, and it is impossible to obtain high carbon content. Carbon sequestration products. Therefore, for biomass raw materials with high moisture content, unconventional thermochemical treatment methods such as hydrothermal carbonization (hydrothermal carbonization) or fermentation should preferably be adopted from the perspective of energy consumption. Because the carbon product is easier and more economical to separate from the water after being treated by fermentation or hydrothermal carbonization, ie, evaporative moisture can be escaped using less energy and/or adding more economical additional deep dehydration. In the fermentation process, high water content and nutrients are conducive to the growth of bacteria, and the metabolism of microorganisms will lead to the coupled emission of greenhouse gases. The generated greenhouse gases, such as methane, are even more harmful to the atmosphere than carbon dioxide emissions. For the hydrothermal carbonization process, water will be produced during the hydrothermal carbonization process. The excess medium water generated in the existing hydrothermal carbonization process needs to be treated before it can be discharged, that is, the heat energy and waste contained in the medium water are lost. Therefore, the existing device fails to utilize the characteristics of the hydrothermal carbonization treatment process, and fails to realize the full resource treatment and utilization of biomass.

On the other hand, as the infrastructure for the development of the new digital economy, the data center industry has a significant impact on climate action. With the formation of 5G scenarios and the passage of time, the computing power demand of data centers will continue to grow exponentially. Over the past 2020, more than a million new devices have come online every hour around the world. As technology develops, more and more computing will happen in the cloud. The operation of social systems such as entertainment, home furnishing, tourism, communication, and transportation will rely on a large amount of high-speed data transmission to establish a new digital order. The fundamental reliability of the digital order is largely determined by the guarantee of reliable continuous power, because the computing power of the data center must be provided uninterrupted under all circumstances. If the data center industry itself ignores innovation in new energy technologies, large-scale inefficient data centers may also make the digital economy unsustainable due to the excessive use of fossil energy. At present, measured by per capita emissions, in terms of the current impact of fossil energy consumption on climate change, the rhythm of fossil energy carbon emissions accompanying the synchronous growth of the digital economy will still bring disastrous climate impacts.

However, the data center industry only relies on the redundant reserves of utility grid facilities and on-site bulky backup systems (such as diesel generators + diesel reserves), including uninterruptible power supply systems (UPS), etc., which can no longer guarantee the system and services. reliability. How to realize the miniaturization, cleaning, sustainability and high reliability of the backup system of the data center, and how to realize the sinking of the computing power of the data center have become the technical problems to be solved.

Example 2

The hydrothermal carbonization system of Example 1 was used to process organic carbon-containing materials selected from river sludge or fecal digestate raw materials.

Weigh 10 g of drying experimental raw materials, mix it fully with 130 mL of water, and transfer it to the reaction kettle, and seal the kettle after fully stirring. The autoclave was then heated to the set temperature and held for the set time, and then the autoclave was cooled to room temperature. Open the reactor to take out the solid phase and liquid phase products, separate the solid phase and liquid phase products by suction filtration through a sand filter funnel, wash the solid phase products three times with deionized water, and collect the liquid phase products as much as possible. The collected liquid-phase product was refrigerated for analysis, and the solid-phase product was dried for 48 hours, and weighed after reaching a constant weight, which was the hydrothermal carbide.

Hydrothermal carbide industry analysis:

After drying, the moisture, ash and volatile matter of the sample were directly measured by Kaiyuan Instruments 5E-MAG6700 II automatic Wangye analyzer, and then the content of fixed carbon was calculated by the subtraction method.

Hydrothermal carbide elemental analysis:

After drying, the samples were measured by 5E-CHN2000 element analyzer from Kaiyuan Instrument Company to measure the mass fraction of C, H, and N in the sample, and the mass fraction of S element was measured by 5E-IRS II infrared spectrometer, and then combined with industrial analysis. As a result, the mass fraction of O element was calculated by subtraction.

The formula for calculating the calorific value of the experimental raw material and hydrothermal carbide is as follows:

HHV(MJ•kg ^-1 ) =0.3419C+1.1783H+0.1005S-0.1034O-0.0015N-0.0211A

Among them, C, H, O, N, S, and A represent the mass percentages of carbon, hydrogen, oxygen, nitrogen, sulfur and ash in the raw materials and carbides, respectively.

The calculation formulas of carbide yield, energy density, and energy yield are as follows:

Carbide yield=carbide mass/raw material mass*100%

Energy density = carbide calorific value / raw material calorific value * 100%

Energy yield=carbide yield*energy density.

In the experimental results, the comparative efficiency and results of fecal digestate as biomass raw material are shown in Table 2:

Table 2: Comparison of solid fuel product quality and energy yield after fecal digestate HTC t=5' treatment stool HV(MJ/kg) Carbide yield (%) Energy Density(%) Energy yield (%) tT 5'180 ^o C 18.8 84.5% 0.98 0.83 tT 5'220 ^o C 20.2 67.3% 1.06 0.71 tT 5'260 ^o C 21.5 56.6% 1.12 0.64 fecal digestate raw material 19.1

The comparative efficiency and results of river sludge as biomass feedstock are listed in Table 3:

Table 3: Comparison of quality and energy yield of solid fuel products after treatment with river sludge HTC t=5' river sludge HHV(MJ/kg) Carbide yield (%) Energy Density(%) Energy yield (%) tT 5'200 ^o C 26.91 72.2% 1.08 0.78 tT 5'250 ^o C 29.81 50.4% 1.20 0.61 tT 5'300 ^o C 35.47 41.3% 1.43 0.59 Raw material of river sludge 24.81

The above results show that the energy densification of the river sludge will be greater than that of the manure digestate, but the output of the river sludge solid product is smaller, and the total energy production is smaller. Both wet biomasses have a tendency to increase energy densification with increasing temperature, but the mass yield of solid water coke decreases with increasing temperature.

Example 10

As shown in Figure 5 and Figure 6, the smart microgrid system includes a gas-steam combined cycle thermal power unit module (CHP module), a hydrothermal carbonization module and an ammonia fuel cell; the hydrothermal carbonization module consists of a CHP module The generated waste heat supplies thermal energy.

CHP modules include combined gas and steam units. The gas unit includes a gas generator, a gas turbine, a fuel supply and an air inlet.

The steam unit includes a steam turbine, a steam generator, a steam generator and a waste heat boiler. Wherein, the arrangement positions and connection methods of the steam turbine, the steam generator, the steam turbine generator and the waste heat boiler are known connection methods in the art. The waste heat of the CHP module comes from the waste heat boiler.

The hydrothermal carbonization module is a module that converts waste biomass into carbon-based materials, such as the hydrothermal carbonization system, the hydrothermal carbonization liquid-phase working medium reuse system, and the hydrothermal carbonization liquid provided in the above embodiments. Phase working medium processing device and/or biomass hydrothermal carbonization full resource treatment and regeneration system. The CHP module is arranged near the hydrothermal carbonization module. For example, the waste heat output by the CHP module can be supplied to a hydrothermal carbonization module with a radius of no more than five kilometers (preferably no more than three kilometers) to convert waste biomass into carbon-based material—water coke. Waste biomass is one, two or more of municipal wet garbage, sludge and the like.

The thermal energy of the hydrothermal carbonization reaction device in the hydrothermal carbonization module is supplied by the CHP module. The CHP module (CHP energy efficiency greater than 54%) arranged adjacent to the hydrothermal carbonization module can give full play to the pretreatment of the waste biomass by the hydrothermal carbonization reaction unit. This is because the waste heat (thermal energy) generated by the CHP module Direct use avoids the two conversion links of the traditional process "thermoelectric-electric cooling/thermoelectric-electric heating", reducing heat loss by at least 50%.

The carbonized solid phase material in the hydrothermal carbonization module can provide carbon-based materials, and for this reason, it preferably includes a carbon-based material collection unit. Preferably, the material inlet of the carbon-based material collection unit is connected to the solid phase outlet or the conveying device of the hydrothermal carbonization system, and the material outlet of the carbon-based material collection unit is connected to the carbon pyrolysis device and/or the carbon gasification device device connection. The carbon-based material is subjected to pyrolysis or gasification treatment by the carbon pyrolysis device or the carbon gasification device to convert the carbon-based material into a desired fuel. For example, the gaseous fuel may be one or more of natural gas and the like, such as the synthetic gas in Example 9. Therefore, the carbon-based material collection unit may be connected to a carbon pyrolysis device, by which the carbon-based material (eg, water coke) is pyrolyzed and gasified for ammonia production. The ammonia can be liquefied into liquid ammonia, and used as a liquid refrigerant for cooling of the data center, for example, the cooling of the data center can be realized through a DLC module. The liquid ammonia used for refrigeration can be stored in a liquid ammonia refrigeration energy storage module and recycled, or used to produce hydrogen using methods known in the art.

Carbon-based materials can replace or supplement at least part of the pipeline gas as a CHP module (that is, as a clean fuel for the CHP module), further reducing the cost of cleaning and repairing landfills.

The hydrothermal carbonization module further includes a hydrothermal carbonization medium water treatment unit, for example, the treatment unit includes at least a heavy metal removal circuit (preferably a circulating electrospinning extraction circuit) for removing heavy metal ions in the hydrothermal carbonization medium water. The hydrothermal carbonization medium water treatment unit is connected with the liquid phase outlet of the hydrothermal carbonization reaction device.

The heavy metal removal loop (or the cyclic electrospinning extraction loop) is connected with the heavy metal extraction reactor; the hydrothermal carbonization medium water treated by the heavy metal extraction reactor returns to the hydrothermal carbonization module through the heavy metal removal loop.

Ammonia fuel cell modules are used as green emergency and backup power sources for smart microgrid systems.

In one embodiment, the smart microgrid system further includes a refrigeration energy storage module. The cooling energy storage module is driven by the waste heat generated by the CHP module.

A refrigeration storage module includes a refrigeration unit, a cold energy storage device and/or a supply conditioning device. The refrigeration energy storage module may also include an air conditioning refrigeration energy storage module. For example, the cold energy storage device may be a cold storage pool.

Cold energy storage devices or cold storage pools contain server (or cabinet) direct cooling function modules (DLC modules). The direct cooling function module contains a liquid medium, and the liquid medium at least has the function of cooling the hardware and/or the space that dissipates heat. The hardware that dissipates heat can be an IT device (such as a server).

The cold energy storage device may be a liquid medium cold storage container. The liquid medium cold storage container can be mainly integrated by conduits and (terminal) heat exchangers, and the layout of conduits is preferably to achieve optimal cooling and energy storage effects. Thus, the comprehensive energy consumption of space cooling, DLC module cooling, and air conditioning cooling can be minimized.

The cold energy storage device may contain cold water storage tanks and ice storage tanks. Both the cold water storage tank and the ice storage tank are arranged underground; it is also preferably arranged near the refrigeration unit.

Those with ordinary knowledge in the art can understand that refrigeration units, cold energy storage devices, supply adjustment devices (such as water storage devices and/or ice storage devices), cold storage pools, direct cooling function modules, liquid medium cold storage containers, cold storage devices The number of water tanks, ice storage tanks, etc. can be adjusted according to the application scale of the smart microgrid system.

Specifically, the heat load steam co-produced by the CHP module directly drives the refrigeration energy storage module, and the refrigeration unit directly bears the steam load, and uses the combination of a large underground cold water storage tank and an ice storage tank to freeze the cold energy after steam cooling. The water medium can store and adjust the cooling energy, which can smooth the fluctuation of the user's cooling demand. Large-scale supply regulation devices (water storage devices) can also perform effective "peak and valley" energy storage regulation.

The main grid supplies power to the data center through the main grid controller, and the smart microgrid supplies power to the data center through the smart microgrid central control system, and/or provides power and heat for cooling energy storage modules and/or heating modules.

When the data center is connected to the main grid, the main grid supplies power to the equipment in the data center, and the smart microgrid supplies power and heat to the cooling energy storage modules that cool the data center, and/or heat the data center. The said heating module provides power and heat;

When the main grid fails, it can automatically switch to the smart microgrid to supply power to the data center, and the cooling of the data center is provided by the cold storage pool of the cooling energy storage module.
