Abstract
The utility model relates to a tail gas heater for a petroleum production well head and belongs to the field of petroleum production devices. The tail gas heater comprises a heating chamber and a circulation tube arranged inside the heating chamber. The tail gas heater is characterized in that the circulation tube is communicated with a tail gas heating chamber, an electrical heating pipe is arranged inside the heating chamber, the heating chamber is communicated with a negative pressure working chamber, an oil delivery pipeline is mounted inside the negative pressure working chamber, the heating chamber is filled with a superconductive medium, and the tail gas heating chamber is communicated with an exhaust pipe of a gas power generator through a gas delivery pipe. The tail gas heater of the petroleum production well head has the advantages of high heating efficiency, low energy consumption, higher safety and simple structure, can effectively prevent the problem of wax deposition of gas delivery pipe and can heat the crude oil with the high-temperature tail gas from the gas power generator, so as to achieve the purposes of energy saving and emission reduction.
Description
Technical field
The utility model relates to the petroleum recovering device field, especially a kind of tail gas heating apparatus of petroleum recovering well head crude oil.
Background technology
In the recover petroleum process, crude oil during from underground extraction because of being subjected to the influence of stratum and air themperature, its temperature reduces gradually, especially winter, the crude oil speed that temperature reduces in the transmission course in pipeline was faster, thereby on the oil pipeline inwall of outer wellhead, be easy to occur the wax deposition phenomenon, cause the reduction of oil transportation efficient, in order to prevent the wax deposition phenomenon, the oil exploitation mining site generally uses heating furnace that the well head petroleum pipeline is heated at present, heating furnace is mainly water batch heater, and water batch heater is to add coil pipe in the water jacket, in the water jacket after the water heating with heat transferred coil pipe inner fluid, this heating furnace is for yielding poorly, intermittently fuel-displaced oil well is inapplicable, fluid is heated when fuel-displaced, and furnace heat does not distribute and do not go out when fuel-displaced, causes the water jacket internal pressure too high dangerous, the bad adjustment of combusting firepower, the efficiency of heating surface is low, the equipment heaviness.Can produce a large amount of natural gases in the oil recovery process, in order to prevent this part natural gas waste, generally adopt the firing method generating, the electric power that sends uses for producing well, generator can be discharged a large amount of high-temperature tail gas in power generation process, and the entrained a large amount of heats of this part high-temperature tail gas are wasted.
Summary of the invention
In order to overcome the above-mentioned technical deficiency of existing oil pipeline warmer, the utility model provides a kind of tail gas warmer of petroleum recovering well head, this warmer is efficiency of heating surface height, saving energy consumption not only, and security reliability height during to heating crude oil, the high-temperature tail gas that can utilize gas electricity generator to produce heats crude oil, thereby reaches the purpose of energy-saving and emission-reduction.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tail gas warmer of petroleum recovering well head, be provided with the heating work chamber, the indoor circulation pipe that is provided with of heating work, it is characterized in that circulation pipe is connected with the tail gas heating chamber, the indoor electric heating tube that is provided with of heating work, the heating work chamber is connected with the negative pressure service depot, and negative pressure is equipped with petroleum pipeline in the service depot, the indoor superconductive medium that is full of of heating work, the tail gas heating chamber is connected with the stack of gas electricity generator through appendix.
The beneficial effects of the utility model are, efficiency of heating surface height, energy consumption are few, and have higher safety, simple in structure, can prevent petroleum pipeline wax deposition phenomenon effectively, the high-temperature tail gas that can utilize gas electricity generator to produce heats crude oil, thereby reaches the purpose of energy-saving and emission-reduction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. tail gas heating chambers among the figure, 2. heating work chamber, 3. circulation pipe, 4. electric heating tube, 5. superconductive medium, 6. petroleum pipeline, 7. negative pressure service depot.
The specific embodiment
In Fig. 1, be provided with heating work chamber 2, be provided with circulation pipe 3 in the heating work chamber 2, circulation pipe 3 is connected with tail gas heating chamber 1, be provided with electric heating tube 4 in the heating work chamber 2, heating work chamber 2 is connected with negative pressure service depot 7, and petroleum pipeline 6 is installed in the negative pressure service depot 7, be full of superconductive medium 5 in the heating work chamber 2, tail gas heating chamber 1 is connected with the stack of gas electricity generator through appendix.The stack of gas electricity generator is discharged high-temperature tail gas and is entered tail gas heating chamber 1 through appendix, and enter in the circulation pipe inherent heating work chambers 23 superconductive mediums 5 in the heating work chamber 2 are heated, petroleum pipeline 6 in 5 pairs of negative pressure service depots of superconductive medium after the heating 7 heats, thereby the heating crude oil in the petroleum pipeline 6 is heated up.
If the utility model tail gas heating heat is not enough, can connects the power supply of electric heating tube 4, thereby assist heating.
