Abstract
The utility model provides a petroleum heating furnace which relates to a heating device for petroleum produced from an oil well. The petroleum heating furnace is provided with a circular-ring-shaped sealing body which is composed of an oil crust, a water crust, a fire pipe and accessories, wherein, a petroleum body is arranged between the oil crust and the fire pipe, and a water body is arranged between the oil crust and the water crust; petroleum flows in the oil crust in a low position and flows out in a high position, the petroleum is directly heated by a furnace body instead of originally being indirectly heated by the furnace body, and the petroleum is discharged from the furnace after being preheated instead of simultaneously flowing in and flowing out of the furnace; so thermal energy storage is realized, furnace temperature is prevented from being too high, and the petroleum in an oil storage tank can be heated in thermal cycling mode. The utility model also has the advantages of capability of supplying a fuel gas source and a fuel oil source, simple structure, one stove with multifunction, and improvement of thermal efficiency.
Description
The utility model discloses a kind of general oil well oil heating furnace that heats usefulness, more be applicable to stripper well.
At present the heating furnace that uses of oil exploitation mining site mainly contains water batch heater and coil pipe heating furnace, water batch heater be in heat(ing) coil in the water jacket, the water jacket after the hydro-thermal with heat transferred coil pipe inner fluid, belong to indirect heating.This heating furnace is inapplicable for the oil well that yields poorly, intermittence is fuel-displaced, and fluid is heated when fuel-displaced, and furnace heat does not distribute and do not go out when fuel-displaced, causes the water jacket internal pressure too high dangerous, the bad adjustment of combusting firepower.Fluid outes while advancing, and is short at residing time in furnace, the heating weak effect.Coil pipe heating furnace is that flame directly burns coil pipe, efficiency of heating surface height, but oil well when not fuel-displaced coil pipe burn high temperature, the coil pipe inner fluid can coking, stops up coil pipe and makes its damage.
The utility model oil heating furnace purpose is the oil heating furnace of a kind of oil well heating usefulness that designs at on-the-spot heating furnace defective.
This oil heating furnace is that following mode realizes: this heating furnace is made up of oilcan, water hull, fire tube and pipeline accessory, and its structure is that fire tube is installed in the oilcan, and oil pipe is put in the oilcan bottom, and top takes on oil pipe, top dress Gas Pipe.The outer water hull of oilcan dress, dress clear water in the water hull, low temperature oil is entered by the oilcan bottom, and the heating high temperature oil has top to flow out.The top natural gas can for the fire tube internal combustion to oilcan in oil heating.Oil is warm can be the water in the heat transferred water hull when high, and the oilcan inner fluid produces oil vapour and promotes fluid and continue to flow, and prevents that fluid from losing mobile blocking pipeline.If single oil well produces oil oil storage tank fortune oil is arranged, can cancel water hull during with this heating furnace, and make the oilcan storage tank heated oil that circulates add hot oil wells output oil simultaneously.
Below in conjunction with schematic diagram this oil heating furnace is further described, figure one is the structural representation of this heating furnace.
Oilcan (1) has the heavy wall steel cylinder to make, two ends are the circular arc end socket, constitute an integral body, open circular hole at two ends, its underpart, fire tube (3) is passed by circular hole and is connected at the circular hole place with oilcan, water hull (2) and oilcan structure and identical with the fire tube connected mode, and the water hull external diameter is greater than oilcan, wrap in the oilcan outside, filling 1/3-2/3 asks water between oilcan and the water hull.Be full of oil gas liquid between oilcan and the fire tube.Top is fluid, and the top is a natural gas, and natural gas bag (12) is adorned at the oilcan top, gas bag top dress natural gas tube (5).The oilcan lower openings is put into oil pipe (6), puts into fuel tap (7) on the oil inlet pipe, and oilcan top takes on oil pipe (8), takes on fuel tap (9) on the flowline.It is low pressure that oilcan is imported and exported pipeline, so oilcan meter design work pressure also be low pressure, and water hull bears the hydro-thermal bulbs of pressure, is low-pressure designs, gas bag import and export pipe valve design with now use identical.For keeping profit shell designing requirement volume, increase its compression resistance under the same volume again, can reduce its internal diameter, increase length, horizontal installation.Fire tube (3) is the high heat conduction steel pipe of heavy wall, and the one end is fire door (15), the built-in right gas nozzles of fire door, (16), and apart from fire door 1-1,5 meters inner chambers (14) dress grease baffle (13), grease baffle is a steel plate, it is flat-shaped going up disconnected, below with inner chamber footpath circular arc together.Highly be the 1/4-1/3 of intracavity diameter, inner chamber is the internal diameter of fire tube, fire tube other end dress chimney (4), and chimney also is a tubular body, is steel pipe or the making of other refractory materials.Heating furnace work process: dress clear water in the water hull, open the oil-feed of turnover fuel tap oilcan, the some stove heats up, and makes oil outlet temperature control claimed range.When not fuel-displaced, stove inner fluid temperature raises, and fluid advances to oil gathering station in the fluid generation steam promotion pipeline, simultaneously water in the heat transferred water hull, makes its rising temperature.When oil temperature is low again heat transferred fluid.When the oil storage tank of individual well fortune oil heats oil, water hull can be saved, install additional from oil storage tank bottom oil return pipe (10), oil return valve (11), the flowline oil advances jar by the oil storage tank high-order bit.Its working method is temperature rising after the heating crude oil in the oilcan, quality lightens, enter oil storage tank top along flowline, bottom and oil well inlet oil temperature are low, there is the oilcan bottom to enter, after heating, there is flowline to flow into oil storage tank top, and formed oil well produce oil liquid and advance stove and heat and enter oil storage tank top self circulation after oil tank bottom, laggard oil storage tank top low temperature oil advances stove heating, reached like this oil well has been gone out fluid and oil storage tank inner fluid circulation heating, to keep the oil tank inner fluid cold season higher temperature to be arranged again and be convenient to the entrucking emptying, saved extra heating source.
In its advantage: 1, this heating furnace can directly heat oil, thermal efficiency height, quick heating.2, enter the sole by the oil limit and come out of the stove and come out of the stove for preheating, heat energy can store, relay, and the prevention furnace temperature is too high.3, can be for the output thermal source.4, be heating furnace, oil gas also can supply gas fuel in the oilcan, reaches multi-use, and compact conformation reduces wellsite facility.
Fig. 1 is this heating furnace structure schematic diagram:
Form by oilcan (1) water hull (2) fire tube (3) chimney (4) tracheae (5) oil inlet pipe (6) inlet valve (7) flowline (8) delivery valve (9) oil return pipe (10) oil return valve (11) gas bag (12) grease baffle (13) inner chamber (14) nozzles (15) fire doors (16).
Embodiment 1: this heating furnace can be realized by following measure, scatters and disappears for preventing heat, can wrap up heat-barrier material at stove outer covering.
Embodiment 2: for preventing the hypertonia damage equipment, can the protection of safety valve class be installed at oilcan and water hull.
Embodiment 3: this heating furnace has the plurality of specifications model, is used for other heating occasion.
