Summary of the invention:
In order to overcome the deficiency of prior art; The object of the present invention is to provide a kind of oil field to use crude oil heater; When carrying out heating crude oil; Can remove the solids such as sand grains in the crude oil earlier, again crude oil heated, have the advantages that anti-wear, anti-clogging, anti-thermal resistance form, raise the efficiency, save the service life of cost, raising heating furnace.
The present invention realizes above-mentioned purpose through following technical scheme.
In the structure of a kind of oil field, be provided with burner, housing, explosion proof door, flue, after-burner, sand removing hole, see fire tube, outlet flue, smoke pipe, crude exports pipe, crude oil inlet tube, hydrocyclone, crude oil overflow pipe, heat exchange coil, vacuum holdout device with crude oil heater; Below the housing left end, burner is installed; In the centre position of case top the vacuum holdout device is installed; Bottom in housing is provided with the combustion chamber of being made up of flue; Burner is positioned at the combustion chamber; Below the combustion chamber, be provided with an explosion proof door, explosion proof door is connected with housing with flue; What be connected with the rear end, combustion chamber is after-burner; Be equipped with at the other end of after-burner and see the fire tube; Right-hand member at housing is equipped with outlet flue, and the outlet of smoke pipe is installed in the outlet flue, and smoke pipe is curved in being installed in housing, and the other end of smoke pipe is mounted on the top of after-burner; Right-hand member in housing is equipped with hydrocyclone, and the bottom of the sand water collecting chamber below hydrocyclone is provided with sand removing hole; Side at hydrocyclone is equipped with the crude oil inlet tube, at the top of hydrocyclone the crude oil overflow pipe is installed; The inlet of the heat exchange coil in the outlet of crude oil overflow pipe and the housing is connected; After crooked coiling, outlet is connected with the crude exports pipe heat exchange coil in housing.
The present invention has following beneficial effect compared with prior art:
1, adopt hydrocyclone to remove the solids such as sand grains in the crude oil earlier, crude oil is heated again, simple in structure, separative efficiency is high, adaptability is good.
2, reduce the impurity that gets into fluid in the heating furnace, reduced the wearing and tearing and the obstruction of solid heat exchanging coil pipes such as sand grains, reduced the formation of fouling, guaranteed the stablizing of unobstructed and flow of heat exchange coil effectively, also guaranteed the heat transfer efficiency of heat exchange coil.
3, anti-wear, anti-clogging, efficient is high, cost is low, service life of having improved heating furnace.
Description of drawings:
Fig. 1 is the general structure sketch map of a kind of oil field with crude oil heater.
In the drawings: 1. burner, 2. housing, 3. explosion proof door, 4. flue, 5. after-burner, 6. sand removing hole, 7. see fire tube, 8. outlet flue, 9. smoke pipe, 10. crude exports pipe, 11. crude oil inlet tubes, 12. hydrocyclones, 13. crude oil overflow pipes, 14. heat exchange coils, 15. vacuum holdout devices.
The specific embodiment:
The present invention by burner 1, housing 2, explosion proof door 3, flue 4, after-burner 5, sand removing hole 6, see that fire tube 7, outlet flue 8, smoke pipe 9, crude exports pipe 10, crude oil inlet tube 11, hydrocyclone 12, crude oil overflow pipe 13, heat exchange coil 14, vacuum holdout device 15 form; Below housing 2 left ends, burner 1 is installed; Centre position at housing 2 tops is equipped with vacuum holdout device 15; Bottom in housing 2 is provided with the combustion chamber of being made up of flue 4; Burner 1 is positioned at the combustion chamber; Below the combustion chamber, be provided with an explosion proof door 3, explosion proof door 3 is connected with housing 2 with flue 4; What be connected with the rear end, combustion chamber is after-burner 5; Be equipped with at the other end of after-burner 5 and see fire tube 7; At the right-hand member of housing 2, outlet flue 8 is installed, the outlet of smoke pipe 9 is installed in the outlet flue 8, and smoke pipe 9 is curved in being installed in housing 2, and the other end of smoke pipe 9 is mounted on the top of after-burner 5; Right-hand member in housing 2 is equipped with hydrocyclone 12, and the bottom of the sand water collecting chamber below hydrocyclone 12 is provided with sand removing hole 6; Side at hydrocyclone 12 is equipped with crude oil inlet tube 11, at the top of hydrocyclone 12 crude oil overflow pipe 13 is installed; The inlet of the heat exchange coil 14 in the outlet of crude oil overflow pipe 13 and the housing 2 is connected; After crooked coiling, outlet is connected with crude exports pipe 10 heat exchange coil 14 in housing 2.
