Second, hydrogen energy storage can be got up by alloy hydrogen container 13, then be used for fuel cell power generation as needed The power generation of device 14 and kitchen garbage recovery vehicle 15 drive, and can also be sold in the form of hydrogen.
When specifically used:
First kitchen garbage processing integrated apparatus 1 be crushed, magnetic separation, slurrying and separation, generate waste oil and fluidised form Rubbish;Wherein waste oil is further processed in biodiesel pretreatment unit 2 generates byproduct biodiesel.Fluidised form rubbish benefit Homogeneous pond 4 is delivered to beater 3 and carries out homogeneous, caching and water quality adjustment, then fluidised form rubbish is transported to by the first pump 5 and is detested Oxygen digester 6 carries out anaerobic reaction and generates biogas residue and biogas.Wherein biogas residue is transported to biogas residue liquid bath and separation dress by the second pump 7 17 generation compost and sewage are set, then the biogas storage of generation carries out desulfurization by desulfurization and decarburization device 9 and take off in tank for sewage gas 8 The purifying process such as carbon are changed into natural gas.Natural gas is divided into two parts, and a part passes through the reaction of reformer 10 together with vapor and produces The gases such as raw hydrogen, carbon monoxide, are filtered purification by purification devices 11, the high-purity hydrogen of acquisition is stored in hydrogen container 12 In.According to specific needs, high-purity hydrogen obtained is used directly for the power generation of fuel cell power generating system 14, kitchen garbage recycling Vehicle 15 is flushed with hydrogen and externally provides, and hydrogen storage can also be used for energy storage in hydrogen storing alloy powder by alloy hydrogen container 13, then According to specific needs, alloy hydrogen container 13 absorbs heat, and dehydrogenation is directly used in the power generation of fuel cell power generating system 14, kitchen garbage recycles Vehicle 15 is flushed with hydrogen and externally provides.
The purifying process such as desulfurization and decarburization, which are carried out, by desulfurization and decarburization device 9 is changed into another part of natural gas in boiler Burning generates thermal energy in 16, these high-quality heat energies are first used for reformer 10, generally require and be heated to 300 DEG C~800 DEG C.Then It is used to kitchen garbage processing integrated apparatus 1 together with the waste heat of fuel cell power generating system 14 to heat, generally requires and is heated to 90 DEG C or so.Hydrogen subsequently is discharged for alloy hydrogen container 13, generally requires and is heated to 50 DEG C~60 DEG C.It is eventually used for anaerobism Digester 6 generally requires and is heated to 30 DEG C~50 DEG C.
The method of raising kitchen garbage capacity usage ratio based on fuel cell and alloy hydrogen storage technology has energy synthesis The electric energy and thermal energy proportion adjustment that utilization efficiency is high, energy storage capacity is strong, generates are flexible, are to realize kitchen garbage treatment plant energy certainly To self-sustaining ideal style.
