Abstract
The utility model relates to the technical field of thickened oil recovery in oil field, in particular to a mobile steam-injection boiler; a cooling chamber of the steam-injection boiler is arranged between a radiation section and a convection section, a combustor is arranged on the radiation section and connected with an air blower by an air duct, the convection section is arranged above the cooling chamber, a chimney is arranged at the outlet end of the convection section, a fuel oil steam heater adopts an L-type snake-like reciprocating structure, and one or a plurality of tube bundles are arranged in the cooling chamber. In the utility model, the temperature of the chimney is reduced, the probability of acid corrosion of tube bundles at the convection section is reduced, the arranged heated surface is optimized, the integral size of the boiler can be effectively reduced, and the disadvantage of the acid corrosion of the tube bundles at the convection section, caused by overhigh chimney temperature when the existing steam-injection boiler runs, is overcome.
Description
Technical field:
The utility model relates to a kind of oil-field thick-oil production technique field, particularly a kind of packaged type injection boiler.
Background technology:
Injection boiler is widely used in the exploitation of each oil-field thick-oil and super special viscous crude, is the nucleus equipment of thickened oil recovery.The HTHP moist steam that injection boiler is produced is injected oil reservoir, and the crude oil in the heating oil reservoir is with the viscosity of reduction viscous crude, thereby the flowability of increase viscous crude makes it easy to exploitation.But the cigarette temperature was too high when there was operation in the injection boiler on the existing market, and the phenomenon of acid corrosion appears in the convection section tube bank.Boiler also comprises outside home-built equipments such as water-to-water heat exchanger, filter, separator except boiler body, make the complicated integral structure of boiler.
The utility model content:
The technical problems to be solved in the utility model provides a kind of packaged type injection boiler, and this injection boiler has been realized the reduction exhaust gas temperature, reduces the probability that acid corrosion appears in the convection section tube bank, and the preferred arrangement heating surface effectively reduces the boiler overall dimensions.The cigarette temperature is too high when having overcome existing injection boiler and having operation, and the deficiency of the phenomenon of acid corrosion appears in the convection section tube bank.
Technical solution adopted in the utility model is: a kind of packaged type injection boiler, form by chimney, convection section, cooling chamber, radiant section, fuel-steam heater, burner, air channel, air compressor machine, air blast and plunger displacement pump; Cooling chamber is between radiant section and convection section, burner is arranged on the radiant section, burner is connected by the air channel with air blast, convection section is arranged on the cooling chamber top, chimney is at the port of export of convection section, the fuel-steam heater adopts the snakelike reciprocating structure of L type, is provided with single in the cooling chamber or many tube banks.
The arrangement mode of multitube can adopt radially or axially back and forth arrangement in the cooling chamber, also can adopt spiral to rise and arrange; Radially or axially back and forth arrangement mode is that many pipes connect with elbow, back and forth arranges near furnace lining at the cooling chamber inwall; Spiral rising arrangement mode is circular or square for using bending machine that pipe is processed into, and the mode of welding or employing fin panel casing is put into cooling chamber one by one.
The beneficial effects of the utility model are: the utility model is owing to adopted the fuel-steam heater design
Become the snakelike reciprocating structure of L type, add single or many pipes at cooling chamber, replaced original water-to-water heat exchanger equipment, thereby simplified the overall structure of boiler, and fully absorbed flue-gas temperature, thereby reduced exhaust gas temperature effectively by the tube bank of cooling chamber, improve the coolant-temperature gage of going into of convection section inlet, reduce the probability that acid corrosion appears in the convection section tube bank, the preferred arrangement heating surface effectively reduces the boiler overall dimensions.

The specific embodiment:
As shown in Figure 1, a kind of packaged type injection boiler is made up of chimney 1, convection section 2, cooling chamber 3, radiant section 4, fuel-steam heater 5, burner 6, air channel 7, air compressor machine 8, air blast 9 and plunger displacement pump 10; Cooling chamber 3 is between radiant section 4 and convection section 2, burner 6 is arranged on the radiant section 4, and burner 6 is connected by air channel 7 with air blast 9, and convection section 2 is arranged on cooling chamber 3 tops, chimney 1 is provided with single in the cooling chamber 3 or many tube banks at the port of export of convection section 2.
As shown in Figure 2, fuel-steam heater 5 adopts the snakelike reciprocating structure of L type.
The arrangement mode of multitube can adopt radially or axially back and forth arrangement in the cooling chamber 3, also can adopt spiral to rise and arrange; Radially or axially back and forth arrangement mode is that many pipes connect with elbow, back and forth arranges near furnace lining at cooling chamber 3 inwalls, as shown in Figure 3, Figure 4; Spiral rising arrangement mode is circular or square for using bending machine that pipe is processed into, and the mode of welding or employing fin panel casing is put into cooling chamber one by one, as Fig. 5, shown in Figure 6.
The Trunk Line of injection boiler is the water filter, go firmly through water treatment facilities after, enter plunger displacement pump 10, in entering tube bank in the cooling chamber 3 from plunger displacement pump 10, improve the coolant-temperature gage of going into that enters convection section 2 by absorbing the flue gas temperature, water directly enters radiant section 4 after convection section 2 flows out, inject the down-hole through steam-water separator at last.
