Embodiment
Describe in detail below in conjunction with the preferred case study on implementation of accompanying drawing to the utility model.
As shown in Figure 1; A kind of gas oxidation heat of the utility model electricity generating device; Comprise firing chamber 2, steam generator 3, steam electric power unit 4 and at least two energy storage beds 1; Energy storage bed 1 communicates with firing chamber 2, and firing chamber 2 links to each other with steam generator 3 through pipeline, and steam generator 3 links to each other with steam electric power unit 4 through pipeline; All be connected with suction tude 12 and exhaust duct 13 on every energy storage bed, and be connected with supply pipe 31 on the steam generator 3.This device constantly heats methane gas through energy storage bed and reaches its SIT; Make its oxidation Decomposition and heat release in the firing chamber; The soft water that the high-temperature gas that produces gets in the steam generator heating steam generator produces steam, and this steam gets into the generating of steam electric power unit.The environmental pollution that the utility model both can effectively solve drawing-off gas to be caused can also produce a large amount of electric energy and create considerable economic.
Below in conjunction with Fig. 1 further explain; This case study on implementation is established two energy storage beds, adorns ceramic packing in the energy storage bed, and is connected with suction tude 12 and exhaust duct 13 in the bottom surface or the side of every energy storage bed; Suction tude 12 is provided with blower fan 121, and exhaust duct 13 communicates with chimney 131; Firing chamber 2 is located on two energy storage beds, and the firing chamber wallboard is provided with preheat burner 21; Firing chamber 2 links to each other with steam generator 3 through pipeline, and steam generator 3 links to each other with steam electric power unit 4 through pipeline; The bottom surface of steam generator or side are provided with supply pipe 31 and outlet pipe 33, and supply pipe is provided with feed water pump 32, and outlet pipe 33 can directly communicate with the external world or communicate with chimney 131.Steam electric power unit 4 is connected with control cabinet 5 through cable, and control cabinet 5 is connected be incorporated into the power networks cabinet 6 or consumer through cable.Steam electric power unit 4 is provided with condensate pipe 41, and condensate pipe 41 can directly communicate with the external world or communicate with supply pipe 31.This installs everywhere and is equipped with control valve on pipeline, supply pipe 31, suction tude 12, the exhaust duct 13.The quantity of each parts of the utility model is not limited to shown in the accompanying drawing, can be provided with according to actual needs.
Warm-up phase: before the device start, the ceramic packing in the energy storage bed is in the normal temperature state, and starting preheat burner 21 provides heat, the ceramic packing in the energy storage bed is preheating to the temperature that needs.Preheat burner 21 can be to be the burner of fuel with rock gas or liquid gas, also can be to be the burner of fuel with diesel oil.When equipment was in preheat mode, the preheated air methane gas of low density (also) periodically got into wherein energy storage bed after getting into blower fans 121 superchargings through suction tude 12.Arrive the ignition heat that firing chamber 2 absorbs fuel behind the preheated air process energy storage bed, and bring another energy storage bed, drain into chimney 131 through exhaust duct 13 again the heat that absorbs.After several hours, combustion chamber temperature just can reach the gas SIT like this, and this device changes holding state over to.When this device was in preheat mode, the control valve on the corresponding pipeline was closed, and the high-temperature gas in the firing chamber can not get into steam generator 3, and this moment, feed water pump 32 meeting startups were injected into soft water in the steam generator 3 through supply pipe 31.
After the burning room temperature reached more than the gas SIT, preheat burner 5 cut out automatically, and preheat mode finishes.Methane gas periodically gets into wherein energy storage bed after getting into blower fan 121 superchargings through suction tude 12.Methane gas through energy storage bed is heated to more than the gas SIT, gets into firing chamber 2 then, and in the firing chamber, carries out a large amount of heat of oxidation Decomposition release.Gas carries out the oxidation Decomposition generation in the firing chamber part high-temperature gas entering needs the energy storage bed of heat regeneration, and drains into chimney 131 through exhaust duct 13 after cooling to lower temperature.Another part high-temperature gas then enters into steam generator 3, and the soft water in the heating steam generator produces steam, and its temperature reduces the back through outlet pipe 33 dischargings.
