Abstract
The utility model relates to an afterheat comprehensive utilizing device for heating stoves of oil extraction equipment, and is particularly used for the afterheat comprehensive utilization of heating stove sets of the oil extraction equipment of oil fields. Original discharged high value heat energy can be recovered and comprehensively utilized by using an afterheat exchanger, a multiple-path heat exchanger, etc. so that the purpose of energy saving can be realized. Simultaneously, the device can be used for lower smoke exhausting to atmosphere and reducing pollution, and is favorable to environmental protection. The utility model can save large quantity of energy, can reduce production cost, can reduce configuration of special equipment, and is convenient for device management and maintenance.
Description
The fume afterheat that the utility model relates to heater utilizes technology, particularly the waste heat recovery comprehensive utilization device of oil field equipment heating furnace group.
The crude oil that factory is gone back to from the oil well collection by the oil recovery factory, oil field is actually a kind of mixture that comprises Oil, Water, Gas and other impurity.Before crude oil pump is fed into gathering line, need will carry out separating treatment after this mixture heating.Water batch heater is exactly the special equipment of this heating system, and it obtains high heat separated object is heated with burn crude.The flue gas that therefore this heating furnace smoke vent opening is discharged still has very high heat.Outside the smoke vent opening through furnace of above-mentioned water batch heater, the high-value heat that has in the flue gas that takes place in the stove was bled off by direct emptying in the past, lost to have in a large number and utilized the energy that is worth.Atmosphere is directly discharged flue gas also can cause smoke contamination.And this heating system has sizable recoverable amount in the production use in oil field.
The purpose of this utility model is: a kind of oil production equipment heating furnace residual heat integrative use device is provided, utilize afterheat heat exchanger, to be drained high value energy recovery and the comprehensive utilization that bleeds off in the past, thereby realized energy conservation, reduced purpose simultaneously the atmosphere soot emissions.Overcome the defective that prior art exists.
The technical solution of the utility model is: use afterheat heat exchanger will be in the past direct a large amount of heat energy of discharging, reclaim and be used.Wherein afterheat heat exchanger is a core, and it is made of housing, pin-fin tube, smoke inlet and exhanst gas outlet.Wherein pin-fin tube reticulates the layering plain cloth, and pipe network can be several layers.Pin-fin tube is a steel pipe, and evenly the vertical planting steel nail constitutes on the outer wall of steel pipe.At the scene in the production application, water batch heater is many to be used in groups, thereby the water batch heater of many covers and afterheat heat exchanger etc. constitute the utility model, they are worked simultaneously and can obtain a large amount of heat energy, and particularly to get up be very huge to many cover centralized heat energy that afterheat heat exchanger reclaimed.This thermal source not only can be exported heat energy work by multi-path heat exchange device mode, can also carry out different distribution by the heat energy of multi-path heat exchange device output, uses the partial heat energy of multi-path heat exchange device output to heat application directly for blends of crudes to be separated.At this moment can close a part of heating furnace is substituted by it.Remaining heat energy is still kept and is supplied with crude preheater and geyser.The application of heating furnace group residual heat integrative use device can reduce the configuration of original special equipment.
The beneficial effects of the utility model: 1. save a large amount of energy, reduce production costs.2. reduce the primary emission of flue dust, reduce pollution and help environmental protection.3. the configuration that reduces special equipment reduces cost, and is convenient to equipment management and safeguards.

Fig. 2. afterheat heat exchanger internal construction schematic diagram
Fig. 3.Figure ZA-A sectional drawing
Below engage accompanying drawing and describe the utility model in detail: as Fig. 1, connect afterheat heat exchanger 3 on the smoke vent opening 2 of water batch heater 1, the top of afterheat heat exchanger 3 is the smoke vent opening 4 of afterheat heat exchanger.The circulating water pipe of afterheat heat exchanger 3 inside is connected with multiloop heat exchanger 6 with expansion tank 5 respectively.Expansion tank 5 is arranged on multiloop heat exchanger 6 tops, is connected by water pipe between the two.Be provided with crude preheater 9 and geyser 10 in the multiloop heat exchanger 6.The crude oil preheating circuit that the crude oil preheating device 12 that crude preheater 9 is connected with circulation pump 7 constitutes.Heating district 13, circulation pump 11 and geyser 10 are connected to form the heating hot-water return.Be provided with circulation pump 8 between multiloop heat exchanger 6 and the afterheat heat exchanger 3.As Fig. 2, afterheat heat exchanger 3 is made of housing 16 pin-fin tubes, 17 smoke inlets 18 and exhanst gas outlet 15.Wherein pin-fin tube 17 reticulates the layering plain cloth, and pipe network can be several layers.As Fig. 3, pin-fin tube 17 is a steel pipe, and even vertical planting steel nail constitutes on the outer wall of steel pipe.
Embodiment: the crude oil that water batch heater 1 uses the high value heat energy of burning crude oil acquisition to treat separating treatment heats, at this moment afterheat heat exchanger 3 reclaims the high hot flue gas of water batch heater smoke vent opening 2 discharges, flue gas 18 enters afterheat heat exchanger 3 from entering the mouth, successively pass through the pin-fin tube stratum reticulare of plain cloth, burn hot pin-fin tube 17, recirculated water in the pin-fin tube 17 obtains and heat is taken away, thereby realizes the recovery of waste heat.Circulation waterway in afterheat heat exchanger 3 and expansion tank 5, the multiloop heat exchanger 6 becomes a big loop, and water is by circulation pump 8 pumping circulation.The heat that crude preheater 9 and geyser 10 will obtain from multi-path heat exchange device 6 respectively is delivered to crude oil preheating circuit and heating hot-water return, finishes to the crude oil preheating with to the heating of heating district.Burning is carried out the natural device heating furnace of preheating and heating oil-fired steam boiler etc. with crude oil, export to the heat energy of crude preheater and geyser owing to the multi-path heat exchange device and close or be not provided with.Another effect of afterheat heat exchanger is to make by the flue dust in the flue gas of its inner pin-fin tube to obtain sedimentation, reduces the discharging of water batch heater flue dust.
