Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Wherein, 1. turbogenerator, 2. well cementation fracturing pump, 3. waste heat steam boiler, 4. control valve, 5. has the outlet pipe of baffler, 6. gas holder, 7. heat exchanger, 8. small pump, 9. water storage cabinet.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
The present embodiment provides a kind of waste heat recovery heat-insulation system of turbogenerator, as shown in Figure 1, comprise the turbogenerator 1 that drives well cementation fracturing pump 2, the waste gas outlet of turbogenerator 1 is connected with the smoke inlet of waste heat steam boiler 3, after the smoke outlet of waste heat steam boiler 3, connect baffler and outlet pipe 5, form energy input drain passageway prepared by steam.The waste gas outlet of turbogenerator 1 is connected with the entrance of control valve 4, the outlet joint noise reduction device of control valve 4 and outlet pipe 5, bypass circulation when formation Waste Heat Recovery System (WHRS) is out of service.
The steam (vapor) outlet of waste heat steam boiler 3 is connected with the entrance of gas holder 6, and the outlet of gas holder 6 connects the entrance of heat exchanger 7, forms the thermal source supply passage of heating and thermal insulation system.Gas holder 6 leaves air outlet, on-the-spot other operations that need steam of supply.The water inlet of waste heat steam boiler 3 is connected with the water outlet of water storage cabinet 9, form prepared by steam for water passage, steam preparation amount that can control system by the adjusting for water passage.What be connected to form at waste heat steam boiler 3 and water storage cabinet 9 arranges small pump 8 on water passage, can ensure persistency, stability prepared by steam.
The present invention also provides a kind of turbogenerator used heat that reclaims to carry out heating heat preserving method to oil drilling and extracting equipment, comprises the steps.
Step 1, the high-temp waste gas producing while providing power by turbogenerator for the operation of well cementation fracturing pump leads to steam boiler.
Step 2, passes into steam boiler by water source, and after water is heated, gasification forms high-temperature steam; High-temp waste gas is cooling after heat exchange, by having the emission by exhaust pipe of silencing apparatus.
