Description
Technical field：
It the utility model is related to ocean heavy crude heat extraction technical field, more particularly to a kind of marine petroleum development steam injection pot
Stove.
Background technology：
During thickened oil recovery, mainly by injection boiler produce high temperature and high pressure steam injection well bottom heating in crude oil,
Its mobility is improved, achievees the purpose that thickened oil recovery.Heavy crude heat extraction technology comparative maturity on land, but conventional fuel oil
(gas) injection boiler cannot meet the requirements such as ocean thermal recovery floor space is small, compact-sized, automatic controlling level is high.
Utility model content：
The technical problem to be solved by the present invention is to provide a kind of marine petroleum development injection boiler, which realizes
The size of injection boiler is reduced, reduces floor space, automatic controlling level is high, realizes the heating exploitation of ocean viscous crude, carries
High viscous oil yield, easy to maintenance and repair.It is big to overcome existing injection boiler size, takes up a large area, automatic controlling level
Low deficiency.
Technical solution adopted in the utility model is：A kind of marine petroleum development injection boiler, including burner hearth, flue gas
Cooling chamber and convection section；Burner hearth and convection section are horizontal arrangement, and convection section is arranged on upper furnace, between burner hearth and convection section
It is connected by flue gas cooling chamber, burner is arranged on burner hearth side, and heat exchanger is arranged on above burner hearth, heat exchanger shell pass outlet
End is connected with tube bank one end inside convection section, and the tube bank other end is connected with heat exchanger tube pass input end inside convection section, changes
The hot device tube side port of export is connected with tube bank one end inside flue gas cooling chamber, inside flue gas cooling chamber in the tube bank other end and burner hearth
Portion's tube bank is connected.
Burner hearth uses square structure, the Horizontal water cooling that burner hearth includes the end plate of arrangement combustor end and surrounded by square coil pipe
Wall, coil pipe are longitudinally arranged along burner hearth.
Tube bank is made of light pipe and finned tube inside convection section.
The beneficial effects of the utility model are：The utility model realizes the size for reducing injection boiler, reduces occupation of land face
Product, automatic controlling level is high, realizes the heating exploitation of ocean viscous crude, heavy oil production is improved, easy to maintenance and repair.
Brief description of the drawings：
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the schematic diagram of the utility model carbonated drink flow.
Embodiment：
As shown in Figure 1, a kind of marine petroleum development injection boiler, including burner hearth 3, flue gas cooling chamber 4 and convection section 5；
Burner hearth 3 and convection section 5 are horizontal arrangement, and convection section 5 is arranged on 3 top of burner hearth, passes through flue gas between burner hearth 3 and convection section 5
Cooling chamber 4 is connected, and burner 2 is arranged on 3 side of burner hearth, and heat exchanger 1 is arranged on the top of burner hearth 3, reduces to platform area
Occupy.1 shell-side outlet end of heat exchanger is connected with the inside of convection section 5 tube bank one end, the inside of the convection section 5 tube bank other end and heat exchange
1 tube side input end of device is connected, and the 1 tube side port of export of heat exchanger is connected with the inside of flue gas cooling chamber 4 tube bank one end, flue gas cooling
The inside of the room 4 tube bank other end is connected with the tube bank of the inside of burner hearth 3.
Burner hearth 3 uses square structure, the water-cooled wall in flue gas transversal flow burner hearth 3.Burner hearth 3 includes arrangement burner
The end plate at 2 ends and the horizontal water cold wall surrounded by square coil pipe, coil pipe are longitudinally arranged along burner hearth 3.
Flue gas cooling chamber 4 is divided cools down heating surface for circumferential cooling heating surface and end, can avoid burner hearth cigarette high-temperature flue gas
For the direct irradiation of convection section 5, and absorb burner hearth 3 and export high-temperature flue gas heat, while reduce external skin temperatures.
The tube bank of the inside of convection section 5 is made of light pipe and finned tube.Light pipe tube bank connection 1 tube side of heat exchanger, is improved to water temperature
It is more than degree to dew-point temperature.Finned tube absorbs fume afterheat, reduces exhaust gas temperature, improves the thermal efficiency of boiler.
Fuel in burner hearth 3 after burning, through 5 two burner hearth 3, convection section backhauls finally by chimney discharged by flue gas.
As shown in Fig. 2, boiler carbonated drink flow is：Boiler feedwater is sent to 1 shell side of heat exchanger, with changing after the boosting of plunger pump 6
The finned tube restraint in convection section 5 and light pipe tube bank are sequentially entered after the high-temperature water heat exchange of hot 1 tube side of device, after absorbing flue gas heat
Into the tube side of heat exchanger 1, for improving shell side feed temperature, flue gas cooling chamber 4 is entered after the completion of heat exchange, finally reaches burner hearth
1 carries out radiation heat transfer, and generation meets the steam of steam injection requirement.
It is understood that above with respect to the specific descriptions of the utility model, it is merely to illustrate the utility model and is not
The described technical solution of the utility model embodiment is limited to, it will be understood by those of ordinary skill in the art that, still can be with
Modify to the utility model or equivalent substitution, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
