Abstract
The utility model provides a waste heat recovering and utilizing device for petroleum drilling in winter in the north, comprising a diesel smoke waste heat recovering and utilizing section, and a recycle water waste heat recovering and utilizing section, wherein, the diesel smoke waste heat recovering and utilizing section is composed of a thermal-insulating smoke conveying pipeline, a smoke thermal transducer (a steam boiler), a steam cylinder, a draught fan and a heat radiator; the recycle water waste heat recovering and utilizing section is composed of a recycle water and waste heat exchanger, a hot-water cylinder, a water pipeline and a heat radiator. The waste heat recovering and utilizing device solves the waste heat recovery of diesel generating sets for drilling, and the waste heat is skillfully used for drilling work. Therefore, an oil or coal burning steam boiler is omitted, and the waste heat recovering and utilizing device is favorable to the safety production.
Description
The utility model relates to diesel residual heat and utilizes technology, particularly oil drilling diesel engine unit waste heat transducing head.
The exhaust gas temperature that the oil drilling diesel engine unit is discharged is up to 250～500 ℃, the about 600KW of heat energy from waste gas that every chassis is discharged.The cooling water of every diesel engine also wastes the heat energy of 900KW simultaneously.This part heat energy always not to be recycled.The drilling well in winter is because weather cold, and the air-path control system of equipment, fuel, drilling fluid and rig floor operation control system and equipment operation all needs heat tracing, the steam boiler that must to join a steam output be 500～1000Kg/h.If adopt combustion crude oil steam boiler, calculated about 100 tons of every stove burn crude in 120 days by annual operation.Big energy-consuming not only, the thermal efficiency is low, and has unsafe factors such as inflammable and explosive.Do not find diesel engine unit waste heat transducing head by retrieval.
The purpose of this utility model just is to extract heat energy and comes the heating steam stove from diesel smoke waste heat and circulating water waste heat, produce the hot steam of 0.4～0.48MPa, give the heating of drilling well production facility and operational site, thereby finish drilling well and produce the history of using combustion crude oil or coal-fired steam boiler, promptly save a large amount of energy, reduce cost, safe and reliable again.
The utility model is achieved through the following technical solutions: this device comprises diesel smoke waste heat energy converting system and diesel engine cycle water waste heat energy converting system two-part.Wherein the smoke discharging residual heat energy converting system is made up of insulation tobacco transmission pipe, cigarette thermal transducer, vapor can, induced draught fan and radiator.When diesel engine turned round, the high-temperature flue gas of discharge produced hot steam through insulation flue to cigarette thermal transducer (boiler), and is temporarily stored in the vapor can, constantly provides hot steam to rig floor, machine room, pump house, vibrating sieve district.Circulating water waste heat energy converting system is made up of water heat source exchanger, hot-water cylinder, waterpipe and radiator.When diesel engine turns round, utilize the waste heat of circulating water in it that outer circulation water in water heat source exchanger is heated, the outer circulation water that has been heated at first enters hot-water cylinder, from hot-water cylinder come out to deliver to along the waterpipe radiator of fuel oil tank field, fuel oil is carried out heat tracing again.
Above-mentioned insulation tobacco transmission pipe cross section is square, and is divided into three lattice cavitys, and with the smoke-ejecting pipe UNICOM of three diesel engines, the other end of square tobacco transmission pipe is received on the cigarette thermal transducer suction port respectively.Induced draught fan is installed in central exhaust mouth place.The cigarette thermal transducer also claims steam boiler, is core hot type structure, and the elevated temperature heat cigarette passes through from combustion chamber, and water is heated into steam.
Above-mentioned water heat source exchanger adopts inside and outside two circulation consubstantiality heat exchange structure.From circulating water flow over-heat-exchanger in the high temperature of diesel engine, with the outer circulation water in the part heat transferred heat exchanger.Interior circulating water through the air cooler cooling of diesel engine, is got back to diesel engine more then.The outer circulation water that obtains heat energy enters hot-water cylinder, and heat is distributed in the fuel oil tank field of flowing through again, gets back to water heat source exchanger then.Part hot water in the hot-water cylinder also can be delivered to steam boiler.
The utility model had both solved the hot cigarette of diesel engine unit and cooling water heat reclaims problem, dexterously this part waste heat is used for situ of drilling well again, has saved special-purpose combustion crude oil or coal steam boiler; Both reduced drilling cost, safe and reliable again.Can claim killing three birds with one stone.Only more than 130 drilling crew of Shengli Oil Field can save about 1.3 ten thousand tons of crude oil every year, is worth up to more than 750 ten thousand yuan.If apply to the north of the Changjiang river, thousands of rigs can be saved 57,700,000 yuan.
Accompanying drawing is a schematic representation of the present utility model.Wherein, the 1st, rig floor, the 2nd, vapor can, the 3rd, thermal transducer, the 4th, hot-water cylinder, the 5th, the machine oil jar, the 6th, the Numberl diesel fuel jar, 7 is No. 2 diesel fuel tanks, the 8th, vibrating sieve district, the 9th, water heat source exchanger, the 10th, diesel engine.
Further specify as follows to embodiment of the present utility model in conjunction with the accompanying drawings:
This reality is novel, and what select for use is homemade Z12V190B type high-horsepower diesel engine, and three is a unit, for oil drilling provides power source.Three diesel engines extraction heat energy that can turn round simultaneously, but also two-shipper or unit extract heat energy, are decided according to the actual requirements.Because square insulation tobacco transmission pipe inside is divided into three cavitys, so be independent of each other.When initial start, be fuel with 40Kg diesel oil, starting power is 350KW, steam flow is 500kg/h, can reach normal operating conditions down.After the diesel engine 10 normal operations, its high-temperature flue gas enters cigarette thermal transducer 3 through insulation tobacco transmission pipe (not drawing among the figure), water is heated into hot steam and enters vapor can 2, by pipeline hot steam is delivered to rig floor 1 and vibrating sieve district 8 etc. again.Simultaneously, cyclic high-temperature water is introduced into water heat source exchanger 9 in self of diesel engine 10, with the outer circulation water in the part heat transferred exchanger 9, through the air cooler cooling of diesel engine self, returns diesel engine 10 then again.Enter hot-water cylinder 4 after outer circulation water is heated in heat exchanger, by hot-water cylinder come out to deliver to along the water pot line radiator of fuel oil tank field, distribute heat is incubated fuel oil drum 5,6,7 again.Outer circulation water returns water heat source exchanger 9 then, obtains heat energy again.Hot-water cylinder 4 directly provides hot water also can for cigarette thermal transducer 3.Make two-part waste heat transducing head constitute a single unit system.As long as diesel engine does not quit work, above-mentioned working procedure just can be finished and back and forth be carried out automatically.
