Abstract
The utility model relates to a direct-current type phase-change furnace for heating crude oil or natural gas in an oil exploitation field. The direct-current type phase-change furnace consists of a heating furnace and a heat exchanger, wherein the heating furnace is connected with a burner and is internally provided with a water heating coil; the heat exchanger is internally provided with a medium coil; the outlet end of the water heating coil is connected with the inlet end of a heat exchanger shell; and the outlet end of the heat exchanger shell is connected with the inlet end of the water heating coil by a circulating pump. Being as a middle medium, water steam is formed in the coil of the heating furnace, the temperature can reach 180 DEG C, while the heating furnace belongs to a direct-current boiler without explosion danger, so that the direct-current type phase-change furnace is safe and reliable.
Description
Technical field:
It is to belong to a kind of novel oilfield furnace apparatus that the utility model relates to a kind of single flow phase-change furnace.
Background technology
At present, in the oilfield exploitation, be used for the common tube furnace that indirect heater or direct-heating type are arranged of heating furnace of heating in crude oil or natural gas.
The indirect type heating furnace is that water is heated to certain saturation temperature (generally be to be heated to 0.5MPa, produce 158 ℃ saturated vapor), and saturated vapor is heating in crude oil or natural gas again.This indirect type heating furnace should be very safe to inflammable crude oil or natural heating, produces the high temperature saturated vapor but will water be heated to 0.5MPa, so the steam generation part just is equivalent to a steam boiler, and there is explosive danger in boiler itself.Directly-fired kiln is with crude oil or natural gas in the direct heat(ing) coil of flame, and this heating furnace heats is very good, but owing to be that flame directly heats, if the coil pipe leakage, then as easy as rolling off a log breaking out of fire, very dangerous, therefore generally be not used.
Summary of the invention
The purpose of the utility model provides a kind of single flow phase-change furnace, and it can get above two kinds of heating furnaces advantage separately, can overcome the explosive unsafe factor of crude oil or natural gas again.
The utility model single flow phase-change furnace is made up of heating furnace and heat exchanger, and heating furnace is connected with burner; The water heat(ing) coil is set in the said heating furnace, is provided with the medium coil pipe in the heat exchanger, the port of export of water heat(ing) coil links to each other with the entrance point of heat exchanger shell, and the port of export of heat exchanger shell links to each other with the entrance point of water heat(ing) coil through a circulating pump.
Described heating furnace is connected with chimney.
This single flow phase-change furnace belongs to the indirect type heating furnace, is intermediate medium with water, at first through heating furnace the water in the coil pipe is burnt till saturated vapor; Saturated vapor upwards gets in the heat exchanger shell from the coil pipe port of export, and heat is passed to heat exchanger coils, with oil in the coil pipe or natural gas heating; Saturated vapor is condensed into liquid phase water simultaneously; And backflow downwards to the water heat(ing) coil of heating furnace from the outlet of heat exchanger shell, continue to be heated the stove heating and generate water vapour, and then repeat said process.So, intermediate medium water reaches the purpose with medium oil or natural gas heating in the process of successive circulating phase-change.Because heating furnace belongs to direct current cooker, water vapour is in the coil pipe of heating furnace, to form, and temperature can reach 180 ℃, does not have explosion danger extremely, and is safe and reliable.This single flow phase-change furnace starts fast, and the thermal efficiency is high, vapor (steam) temperature is brought up to more than 180 ℃ in 5 minutes, and heat energy is sufficient, can make medium reach desirable temperature rapidly.
Description of drawings
Fig. 1 is a single flow phase-change furnace structural representation.
Among the figure, 1, burner, 2, flue, 3, the water heat(ing) coil, 4, heating furnace, 5, circulating pump, 6, condensate pipe, 7, the medium import, 8, media outlet 9, medium coil pipe, 10, heat exchanger, 11, steam pipe 12, chimney.
The specific embodiment
Like Fig. 1, in this single flow phase-change furnace, be provided with water heat(ing) coil 3 in the heating furnace 4; Heat exchanger 10 is positioned on the heating furnace 4, in be provided with medium coil pipe 9; The port of export of the water heat(ing) coil 3 in the heating furnace 4 links to each other with steam pipe 12 with the entrance point of heat exchanger 10 housings, and the port of export of heat exchanger 10 housings links to each other with condensate pipe 6 with the entrance point of water heat(ing) coil 3 through a circulating pump 5.
The flame that burner 1 produces sprays into heating furnace 4, directly the intermediate medium water in the water heat(ing) coil 3 is heated, and flue gas then upwards turns back after arriving afterbody through heating furnace 4, gets into chimney 12 through flue 2 and enters atmosphere.Intermediate medium water is heated in heating furnace 4 and is gasificated into saturated vapor; Rise to heat exchanger 10 then, with medium oil or heat exchange gas in the medium coil pipe 9, saturated vapor discharges latent heat and condenses into liquid phase water; Return the water heat(ing) coil 3 of heating furnace 4; So, through WATER AS FLOW MEDIUM circulating phase-change process continuously, reach purpose with medium oil or natural gas heating.
Claims (2)
1. the single flow phase-change furnace is made up of heating furnace and heat exchanger, it is characterized in that heating furnace is connected with burner; Be provided with the water heat(ing) coil in the said heating furnace, be provided with the medium coil pipe in the heat exchanger; The port of export of said water heat(ing) coil links to each other with the entrance point of heat exchanger shell, and the port of export of heat exchanger shell links to each other with the entrance point of water heat(ing) coil through a circulating pump.
2. single flow phase-change furnace according to claim 1 is characterized in that described heating furnace is connected with chimney.
