Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of waste heat recovery heat-insulation system of turbogenerator is provided, this heat-insulation system can under extremely cold environment, the turbogenerator used heat of the high-power well cementation fracturing unit of effective recovery, realize the insulation in equipment and other regions, heat insulation work high-efficiency and economic, safe and reliable.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of waste heat recovery heat-insulation system of turbogenerator, comprise the turbogenerator driving well cementation fracturing pump, between the tail gas end of described turbogenerator and the outlet pipe with silencing apparatus, waste heat steam boiler is set, the feed-water end of this waste heat steam boiler is communicated with water storage cabinet, is communicated with after the hot output terminal connection gas holder of waste heat steam boiler with heat exchanger again.
And arrange between described turbogenerator and outlet pipe with waste heat steam boiler and the bypass line connected, this bypass line has control valve.
And, between described waste heat steam boiler and described water storage cabinet, small pump is set.
The utility model 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 one, by turbogenerator for the operation of well cementation fracturing pump provides the high-temp waste gas produced during power to lead 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 cools after heat exchange, by having the emission by exhaust pipe of silencing apparatus.
Step 3, after high-temperature steam being passed into the voltage stabilizing of gas holder buffering, is transported to heat exchanger, carries out heating and thermal insulation by heat exchanger to whole equipment and supporting region.
And described water source is the water in water storage cabinet.
The beneficial effects of the utility model are, the high-temp waste gas produced when utilizing turbogenerator to work, for waste heat steam boiler provides energy to prepare a large amount of high-temperature steam, heat needed for insulation of equipment under extremely cold environment is provided, can be used for the heat preservation and heat supply in equipment and supporting region, also can be used for other operation needs that scene needs steam; This programme is simple and reasonable, can be incorporated in high-power well cementation fracturing unit, be conducive to the lightweight of equipment, and without the need to newly-increased thermal source, waste heat energy regenerating utilization ratio is high, improves safety reliability, the Economy of site operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1. turbogenerator, 2. cement the well fracturing pump, 3. waste heat steam boiler, 4. control valve, 5. have 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 utility model is described in further detail.
The present embodiment provides a kind of waste heat recovery heat-insulation system of turbogenerator, as shown in Figure 1, comprise the turbogenerator 1 driving well cementation fracturing pump 2, the waste gas outlet of turbogenerator 1 is connected with the smoke inlet of waste heat steam boiler 3, to connect after the smoke outlet of waste heat steam boiler 3 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 needing 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, can the steam preparation amount of control system by the adjustment 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 utility model 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 one, by turbogenerator for the operation of well cementation fracturing pump provides the high-temp waste gas produced during power to lead 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 cools after heat exchange, by having the emission by exhaust pipe of silencing apparatus.
Step 3, after high-temperature steam being passed into the voltage stabilizing of gas holder buffering, is transported to heat exchanger, carries out heating and thermal insulation by heat exchanger to whole equipment and supporting region.
The implementation process of the Waste Heat Recovery System (WHRS) of this turbogenerator of the utility model is: when high-power well cementation fracturing unit runs, and turbogenerator 1 drives well cementation fracturing pump 2 to carry out field operation.Meanwhile, turbogenerator 1 produces a large amount of high-temp waste gas, collects the smoke inlet entering waste heat steam boiler 3 through fume pipe; In waste heat steam boiler 3, heat exchange is fully carried out in high-temp waste gas and boiler feed water, and high-temp waste gas releases energy after cooling, discharges through baffler and outlet pipe 5, and after boiler feed water absorption heat, vaporization forms high-temperature steam; High-temperature steam input gas holder 6, gas holder 6 plays the effect of buffering voltage stabilizing, then is transported to heat exchanger 7 through gas holder 6, carries out heating and thermal insulation by heat exchanger 7 to whole equipment and supporting region; The boiler feed water that waste heat steam boiler 3 vaporization consumes, constantly supply supplementary from water storage cabinet 9 by small pump 8, and the turbogenerator 1 of fracturing work of cementing the well continuously also constantly will produce high-temp waste gas, for waste heat steam boiler 3 provides energy, thus ensure the continual and steady of heat-insulation system heat energy.Gas holder 6 also leaves air supply opening, on-the-spot other operations needing steam of supply.Regulate the supply channel of waste heat steam boiler 3 and water storage cabinet 9 can the steam preparation amount of control system.
Run under conventional environment, do not need heating and thermal insulation measure, then use control valve 4 to open exhaust gas bypass loop, the waste gas that turbogenerator 1 produces directly discharges through baffler and outlet pipe 5, and waste heat recovery heat-insulation system quits work.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement or distortion, these improve or distortion also should be considered as protection domain of the present utility model.
