[0043] This invention provides a combined cooling, heating, and power (CCHP) system for a gas-fired heat pump driven by a mixture of biomass fermentation and gasification. The system includes a biomass fermentation device, a biomass gasification device, a gas-fired CCHP device, and a control device. The biomass gasification device decomposes biomass to produce combustible gas and supplies it to the outside. The gas-fired CCHP device provides cooling, heating, and power to the outside. The control device controls the operation of the biomass fermentation device, the biomass gasification device, and the gas-fired CCHP device. Specifically, the control device controls the biomass fermentation device to convert biomass into biogas and controls the biomass gasification device to convert biomass into gasified combustible gas. It then supplies either the biogas or the gasified combustible gas separately to the outside, or mixes the biogas and gasified combustible gas in a preset ratio before supplying them to the outside, or mixes the biogas and gasified combustible gas in a preset ratio and supplies it to the gas-fired heat pump CCHP device for energy conversion and output, thereby providing cooling, heating, and power to the outside.

The gas engine drives the generator set to generate electricity, which can be supplied to external electrical loads through the power grid connection cabinet, or the generated electricity can drive the air source heat pump to generate heat. After generating heat, the air source heat pump can supply heat to external heat loads together with the flue gas heat exchanger and the cylinder liner water heat exchanger, or store the heat in a heat storage tank. The absorption chiller absorbs the heat from the heat storage tank and supplies cooling to external cooling units. Furthermore, the control device includes several sensors, a safety explosion-proof valve, a flame arrester, and a gas shut-off solenoid valve.

[0045] Specifically, the combined cooling, heating, and electrical power supply system of the present invention, which integrates biomass fermentation and gasification to drive a gas-fired heat pump, constructs a highly integrated and synergistically efficient energy supply system. The biomass fermentation device and the biomass gasification device together serve as the source of energy production. Through the coordinated operation of the biogas digester and the biomass gasifier, biomass raw materials are processed in a diversified manner to produce biogas or combustible gases of different compositions. The biogas digester utilizes the fermentation of microorganisms to convert the organic matter in biomass into biogas, while the biomass gasifier converts biomass into gas rich in carbon monoxide, hydrogen, and other components through high-temperature pyrolysis and other processes. A gas purifier deeply purifies the gas produced by the biomass gasifier, removing impurities and harmful components (such as carbon dioxide, hydrogen sulfide, sulfur, or dust) to ensure that the gas quality meets the requirements for subsequent use. The purified gas is thoroughly mixed with the biogas produced by the biogas digester in a gas mixer to form a stable and uniformly calorific mixed gas, thus providing high-quality raw materials for subsequent energy conversion. The gas-fired combined cooling, heating, and power (CCHP) system is responsible for converting the mixed gas into energy in three forms: cooling, heating, and electricity. Through reasonable distribution and transmission, it meets the diverse needs of different external users. The control device monitors and precisely controls the operating parameters of each unit in real time, achieving efficient, stable, and safe operation of the system and greatly improving the overall energy utilization efficiency.

[0046] In a gas-fired combined cooling, heating, and power (CCHP) system, the gas engine serves as the power source. It generates high-temperature, high-pressure gas by burning a mixture of gases, driving a turbine to rotate at high speed and converting chemical energy into mechanical energy. The gas engine is closely connected to a generator set; the turbine's rotation drives the generator's rotor, generating electricity, which is then transmitted to the external power grid via a grid-connected cabinet, providing stable power support for various electrical loads. During gas engine operation, the generated cylinder liner water carries a significant amount of waste heat. A cylinder liner water heat exchanger transfers this heat to the external heat medium through heat exchange, providing a heat source for the heating system. Simultaneously, the high-temperature flue gas discharged from the gas engine contains abundant thermal energy. A flue gas heat exchanger further recovers this heat, transferring it to water or other working fluids to generate high-temperature steam or hot water for heating or driving an absorption chiller. The absorption chiller utilizes thermal energy as its driving energy, achieving a cooling effect through a phase change process with working fluids such as lithium bromide-water, providing cooling capacity to external cooling units. Air source heat pumps, through the cyclical operation of a compressor, condenser, expansion valve, and evaporator, absorb heat from the air and then use it for heating, further enriching the system's heating methods. This multi-device collaborative operation mode achieves cascaded energy utilization and greatly improves energy efficiency.

[0047] The control unit comprehensively monitors the system's operating status through multiple sensors. The first pressure sensor monitors the gas engine's intake pressure in real time, ensuring the gas pressure entering the engine remains stable within a suitable range, guaranteeing the stability and efficiency of the combustion process. The second pressure sensor monitors the gas engine's oil pressure. Stable oil pressure is crucial for the gas engine's lubrication and cooling; if the oil pressure is abnormal, the control unit will promptly issue an alarm and take corresponding measures to prevent equipment damage due to insufficient lubrication. The first and second temperature sensors detect the exhaust temperature of the flue gas heat exchanger and the water temperature of the cylinder liner water heat exchanger, respectively. By monitoring these temperature parameters, the control unit can adjust the system's operating status in a timely manner, optimize heat exchange efficiency, and prevent equipment damage due to overheating. To ensure safe system operation, the control unit is also equipped with multiple safety protection devices, including explosion-proof valves, flame arresters, and gas shut-off solenoid valves. The gas engine, generator set, air source heat pump, cylinder liner water heat exchanger, and flue gas heat exchanger are all equipped with explosion-proof valves. When the internal pressure of the equipment exceeds a set value, the explosion-proof valves will automatically open to release pressure and prevent equipment explosion. Gas engines, generator sets, and air source heat pumps are all equipped with flame arresters, which effectively prevent the spread of flames and avoid fire accidents. The gas shut-off solenoid valve installed in the gas engine can quickly cut off the gas supply in emergencies, preventing gas leaks and potential hazards. The synergistic effect of these safety devices provides a solid guarantee for the safe and stable operation of the system.

[0048] As an alternative implementation, in some embodiments, the heat exchange medium of the flue gas heat exchanger is water, air, or an organic medium. When water is chosen as the heat exchange medium, its excellent thermophysical properties, such as high specific heat capacity, allow it to efficiently absorb heat from flue gas, heating it into high-temperature steam or hot water. These heat carriers can be flexibly applied to heating systems, providing a warm and comfortable indoor environment for buildings, and can also be used in heating processes in industrial production to meet the heat energy requirements of different processes. If air is used as the heat exchange medium, air is widely available and inexpensive to obtain. After exchanging heat with high-temperature flue gas through a flue gas heat exchanger, the heated air can be directly sent into spaces requiring ventilation and heating, such as large factories and greenhouses, to achieve the purpose of heating. When organic working media are used, they have a low boiling point and can vaporize at relatively low temperatures. This allows the flue gas heat exchanger to efficiently recover waste heat under low flue gas temperature conditions. After vaporization, the organic working media enters a specific power cycle system, where it can further convert heat energy into mechanical energy or electrical energy, improving the overall energy utilization efficiency and bringing more significant energy-saving and economic benefits to the system.

[0049] As an optional implementation, in some embodiments, the absorption chiller uses ammonia or lithium bromide as the refrigerant. When ammonia is used as the refrigerant, ammonia has excellent thermodynamic properties, a large latent heat of vaporization, and can absorb a large amount of heat at low temperatures to achieve efficient refrigeration. It is also relatively inexpensive and widely available. Water, as the absorbent, has a strong absorption capacity for ammonia. The working fluid pair composed of these two substances can operate within a wide temperature and pressure range, making it suitable for large-scale industrial refrigeration scenarios. When lithium bromide is used as the refrigerant, water is used as the refrigerant and an aqueous lithium bromide solution is used as the absorbent. Water evaporates and absorbs heat under vacuum to achieve refrigeration. This method has the advantages of being non-toxic, odorless, and having no destructive effect on the atmospheric environment. It also operates quietly with minimal vibration and is commonly used in environments with high environmental requirements and where stable refrigeration is needed.

[0050] As an optional implementation, in some embodiments, the cylinder liner water heat exchanger includes a low-temperature cooling medium, which can be either fresh water or air. When fresh water is used as the low-temperature cooling medium, it possesses excellent thermal conductivity, enabling it to quickly and efficiently absorb the heat carried in the cylinder liner water, achieving effective heat transfer and exchange. Furthermore, its high specific heat capacity allows it to absorb more heat under the same mass and temperature rise conditions, thus more stably maintaining the cylinder liner water temperature within a reasonable range and ensuring the normal operation of equipment such as gas engines. When air is used as the low-temperature cooling medium, air acquisition is extremely convenient, requiring no additional storage or transportation equipment, resulting in a relatively simple system structure and lower cost. Simultaneously, air as a cooling medium eliminates the risk of leakage and environmental pollution.
