Technical Field

The utility model relates to a temperature control and refrigerating system and coupled system in little grid system, heat energy space belongs to hydrothermal carbonization treatment technical field.

Background

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

On the one hand, because of the large amount of water contained in the wet biomass, the wet biomass must be treated conventionally by evaporating the water therefrom. For example, by three conventional thermochemical reaction processes (torrefaction, pyrolysis or gasification), operating at atmospheric pressure and in an environment that must be above the boiling point of water (> 100 ℃) such that the water is evaporated before the biomass can be heated to the desired reaction temperature. Typical examples are sludge residues from water treatment plants, which are primarily dried before being treated by conventional methods; in addition, other wet biomass materials, such as plant residues that can be used as animal feed, must also be stored by drying. However, the pretreatment procedure of water evaporation drying not only brings huge carbon emission load to the industry, but also wastes a large amount of water resources; on the other hand, for wet biomass feedstocks where the residual moisture of most agricultural or municipal waste is as high as 75%, 80% or higher, the pre-process of evaporative drying also loses the energy contained in the biomass itself.

Meanwhile, the conventional thermochemical treatment of biomass is more suitable for biomass raw materials with low moisture content, such as pure biomass of wood, and the conventional thermochemical treatment also easily causes carbon loss, so that a solid carbon product with high carbon content cannot be obtained. Therefore, for biomass raw materials with a high moisture content, it is preferable to use an unconventional thermochemical treatment method such as hydrothermal carbonization (hydrothermal carbonization) or fermentation from the viewpoint of energy consumption. Because the carbon product is more easily and economically separated from the water after fermentation or hydrothermal carbonization processes, the carbon product can be used with less energy and/or the evaporative water escape of additional deep dewatering that is economical. During fermentation, high water content and nutrients are beneficial for bacterial growth, and metabolism of microorganisms can result in coupled emissions of greenhouse gases, which produce greenhouse gases, such as methane, that are even more harmful to the atmosphere than carbon dioxide emissions. The hydrothermal carbonization process is accompanied with the generation of water in the hydrothermal carbonization process, and redundant medium water generated in the conventional hydrothermal carbonization process can be discharged after being treated, namely, the heat energy contained in the medium water is lost and nutrient substances rich in the medium water are wasted, so that the conventional device cannot utilize the characteristics of the hydrothermal carbonization treatment process and cannot realize full-resource treatment and utilization of biomass.

On the other hand, as an infrastructure for the development of new digital economies, the influence of the data center industry on climate actions is significant. The computational demands of data centers will continue to grow exponentially as 5G scenes are formed and time passes. Over the past 2020, over a million new devices have come online every hour worldwide. With the development of technology, more and more computing will occur in the cloud. Social systems such as entertainment, home, tourism, communication, traffic and the like rely on a large amount of high-speed data transmission to establish new digital order. The basic reliability of digital order establishment depends to a large extent on the guarantee of reliable continuous power, since the computing power of the data center must be provided uninterrupted in any case. If the data center industry itself neglected innovations in new energy technologies, large scale inefficient data centers may likewise result in digital economies becoming non-sustainable due to the overuse of fossil energy. At present, according to the emission per capita, as for the influence of the current fossil energy consumption on climate change, the rhythm of the fossil energy carbon emission along with the synchronous increase of digital economy still brings disastrous climate influence.

The data center industry relies solely on redundant reserves of utility systems and on bulky backup systems in the field (e.g., diesel generators + diesel reserves), including Uninterruptible Power Systems (UPS), etc., to ensure reliability of the systems and services. How to realize the miniaturization, cleanness, sustainability and high reliability of the data center backup system and realize the sinking of the computational power of the data center becomes a technical problem to be solved urgently.

Hydrothermal carbide elemental analysis:

the dried sample is subjected to mass fraction measurement of three elements of C, H and N by using an element analyzer of 5E-CHN2000 type of the Kaiyuan instruments company, the mass fraction of the element S is measured by using an infrared sulfur analyzer of 5E-IRS II type, and the mass fraction of the element O is calculated by using a differential subtraction method in combination with an industrial analysis result.

The cold energy storage device can be a liquid medium cold accumulation container. The liquid medium cold storage container can be mainly integrated by a conduit and a (terminal) heat exchanger, and the arrangement mode of the conduit is preferably optimized to achieve optimal cooling and energy storage effects. Therefore, the comprehensive energy consumption of space refrigeration, DLC module refrigeration and air conditioner refrigeration can be reduced to the minimum.

The cold energy storage device may include a cold storage water tank and an ice storage tank. The cold storage water tank and the ice storage tank are both arranged underground; and preferably also in the vicinity of the refrigeration unit.

when the main power grid fails, the intelligent micro-grid can be automatically switched to supply power to the data center, and the refrigeration of the data center is provided by the cold storage pool of the refrigeration energy storage module.

Example 12

This example provides a coupling system of a hydrothermal carbonization system as in example 1 with a Solar power generation system (micro air brayton cycle turbine module) of Wilson Solar Corp or 247Solar corporation, a schematic of which is shown in fig. 7.

Wherein the carbonized solid phase product (water coke product) provided by the centrifuge is dried in a dryer and converted into gaseous fuel by heating in a gasification medium, such as air, oxygen or steam (which may be carried out in the presence of a catalyst or without a catalyst), at a temperature above 800 ℃. The gasification product is a mixture of carbon monoxide, carbon dioxide, methane, hydrogen and water vapour. Since the higher process temperature facilitates the early cracking process, volatile organics are reduced and fixed carbon is increased. 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 the water coke can reach about 30%.

The gasification products are combined with a Brayton Cycle power generation system (Brayton Cycle CSP) to provide gas to the gas turbine modules of the Brayton Cycle system to operate the turbine modules in the manner of a "gas turbine" module disclosed in PCT international application PCT/US2011/052051 or a "gas turbine" module disclosed in PCT international application PCT/US 2013/031627) to enable energy-to-power conversion. Or alternatively hydrogen produced by ammonia may be used as fuel gas for the gas turbine module.
