The entirety of the aforementioned prior application is incorporated herein by reference.

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

Biomass includes all plants, microorganisms and animals that feed on plants and microorganisms, as well as the wastes generated by metabolism and/or production of plants, microorganisms and animals. The wet biomass includes all organic fractions of inedible agricultural products such as food processing waste, industrial organic waste or municipal solid waste.

On the one hand, due to the large amount of water contained in wet biomass, traditionally Substances must first be evaporated to remove water before they are processed. For example, through three conventional thermochemical reaction processes (torrefaction, pyrolysis or gasification), operating at atmospheric pressure and must be above the boiling point of water (>100 ℃), so that the biomass can be heated to the desired reaction Before the temperature, evaporate the water in it. A typical example is the sludge residue from a water treatment plant, which is firstly 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 be processed by 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; on the other hand, for most agricultural products or urban waste, the residual moisture is as high as 75%, 80% or For higher wet biomass raw materials, the pre-evaporative drying process 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 cannot obtain high carbon content. carbon sequestration products. Therefore, for biomass raw materials with high moisture content, unconventional thermochemical treatment methods such as hydrothermal carbonization or fermentation should be preferred from the perspective of energy consumption. Because after fermentation or hydrothermal carbonization process, the carbon product is easier and more economical to separate from the water, that is, less energy can be used and/or more economical extra deep dehydration can be added. During the fermentation process, high water content and nutrients are conducive to the growth of bacteria, and the metabolism of microorganisms will lead to coupled emissions of greenhouse gases. The greenhouse gases produced by them, 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 produced 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. The rich nutrients in the medium water make the existing device fail to take advantage of the characteristics of the hydrothermal carbonization treatment process. Failed 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. In the past 2020, more than one million new devices have come online every hour around the world. As technology develops, more and more computing will take place 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 basic reliability established by the digital order depends to a large extent on the guarantee of reliable continuous power, because the computing power of the data center must be provided uninterrupted under any 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. Currently measured by per capita emissions, as far as the current impact of fossil energy consumption on climate change is concerned, the rhythm of fossil energy carbon emissions accompanied by the simultaneous growth of the digital economy will still bring disastrous climate impacts.

However, the data center industry only relies on redundant reserves of public power 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 systems and services. reliability. How to realize the miniaturization, cleanliness, sustainability, and high reliability of the data center backup system, and how to realize the sinking of data center computing power has become an urgent technical problem to be solved.

Example 9

As shown in Figure 3 and Figure 4, after the wet biomass is treated by HTC, a carbon-densified water char product is formed, which is pyrolyzed into synthetic gas by fluidized bed pyrolysis technology, and is also heated by fluidized bed Hydrolysis technology, microwave pyrolysis technology, and plasma pyrolysis technology produce high-value carbon-based materials that are pyrolyzed to produce biochar.

Among them, the material balance table of the HTC process is as follows:

Alternatively, the synthetic gas produced by the pyrolysis described above can also be used to produce ammonia (NH ₃ ) by methods known in the art.

Example 10

As shown in Figure 5 and Figure 6, the smart microgrid system includes a gas-steam combined cycle thermoelectric 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.

The CHP module includes combined gas and steam units. The gas unit includes gas generator, gas turbine, fuel supply and air inlet. Wherein, the installation positions and connection methods of gas generators, gas turbines, and fuel supply devices are connection methods known in the art, and the settings of air inlets are installation positions known in the art. The steam unit includes steam turbine, steamer, steam turbine generator and waste heat boiler. Among them, steam turbines, steamers, steam turbine generators and residual The setting position and connection method of the heating boiler are connection methods known 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 provided in the above examples, the reuse system of the hydrothermal carbonization liquid-phase working medium, and the hydrothermal carbonization liquid A treatment device for the phase working medium and/or a biomass hydrothermal carbonization full resource treatment and recycling 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. The waste biomass is one, two or more of municipal wet garbage, sludge, and the like.

The heat 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 waste biomass in the hydrothermal carbonization reaction device, because the waste heat (heat energy) generated by the CHP module Direct use avoids the two conversion links of the traditional process "thermoelectric-electric cooling/thermoelectric-electric heating", slowing down heat loss by at least 50%.

The carbonized solid-phase material in the hydrothermal carbonization module can provide carbon-based materials, for which 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 carbon gasification device connection. The carbon-based material is pyrolyzed or gasified by the carbon pyrolysis device or carbon gasification device to convert the carbon-based material into the required fuel. For example, the gaseous fuel may be one or more of natural gas, such as the synthetic gas in Embodiment 9. Therefore, the carbon-based material collection unit can be connected with a carbon pyrolysis device, through which the carbon-based material (such as water coke) is pyrolyzed and gasified to produce ammonia. said The ammonia can be liquefied into liquefied ammonia and used as a liquid refrigerant for data center cooling, for example, through DLC modules to realize data center cooling. The liquefied ammonia used for refrigeration can be stored in the liquefied ammonia refrigerated 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 piped gas used as CHP modules (that is, as clean fuels for CHP modules), further reducing the cost of cleaning and repairing landfills.

The hydrothermal carbonization module also 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 circulating electrospinning extraction loop) is connected to 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.

The ammonia fuel cell module is used as a green emergency and backup power supply for the smart microgrid system.

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.

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

The cold energy storage device or cold storage pool contains a server (or cabinet) direct cooling function module (DLC module). The direct cooling function module contains a liquid medium, the liquid medium At least it has the effect of cooling the heat dissipating hardware and/or cooling the space. The heat dissipating hardware 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 the conduits is preferably to achieve optimal cooling and energy storage effects. In this way, the comprehensive energy consumption of space cooling, DLC module cooling, and air-conditioning cooling can be reduced to a minimum.

The cold energy storage device may contain a cold storage tank and an ice storage tank. Both the cold water storage tank and the ice storage tank are arranged underground; they are also preferably arranged near the refrigerating unit.

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

Specifically, the thermal 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 the cold energy after steam refrigeration is refrigerated by combining large underground cold storage tanks and ice storage tanks. The water medium stores and adjusts the cold energy, which can smooth the fluctuation of the user's cooling demand. Large-scale supply regulators (storage devices) also allow efficient "peak-to-valley" energy storage regulation.

Example 11

The clean microgrid system of the data center as shown in FIG. 5 and FIG. 6 includes the smart microgrid system and the main power grid in Embodiment 10.

The main grid and the smart microgrid system supply power to the data center through a combination of off-grid and grid-connected.

The clean microgrid system also includes the main grid controller and/or the smart microgrid central control system. 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 supplies power and heat to the cooling energy storage module and/or heating module.

When the data center is running in parallel with 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 module for cooling the data center, and/or provides heating for the data center The heating module for power supply and heat supply; When the main power grid fails, it can automatically switch to the smart micro-grid powering the data center, and the cooling of the data center is provided by the cold storage pool of the cooling energy storage module.

Example 12

This embodiment provides the coupling system of the hydrothermal carbonization system such as Embodiment 1 and the solar power generation system (miniature air Brighton cycle turbine module) of Wilson Solarpower Corp or 247Solar Company, and Fig. 7 shows the schematic diagram of this coupling system .

Among them, the carbonized solid-phase product (water coke product) provided by the centrifuge is dried by a dryer, and at a temperature above 800°C, it is heated in a gasification medium, such as air, oxygen or steam (can be in a catalyst or non-catalytic condition carried out below) into gaseous fuels. The gasification product is a mixture of carbon monoxide, carbon dioxide, methane, hydrogen and water vapour. Because the higher process temperature promotes the early cracking process, it reduces VOCs and increases fixed carbon at the same time. The biochar residue produced by the gasification process has a higher carbon and ash content than the biochar produced by the pyrolysis process. The ash content of water coke can reach about 30%.
