Abstract

A novel electric heater for petroleum relates to a field heating device for petroleum production of oil well, which consists of an inner pipe, an electrothermal body, a superconductor, a heat insulation layer and a casing and is used in middle-low yield oil well. Petroleum enters the inner pipe from a lower part and flows out from an upper part after electric heating. The utility model changes working mode of the prior heating furnace and supplies heat by the electrothermal body with constant temperature. The petroleum flows out after preheating, and the superconductor enhances thermal efficiency. As open fire is not used in heating, the electric heater has safe working, convenient operation, no water adding, a simple structure and easy maintenance.

Description

The oil electric heater

The utility model oil electric heater relates to a kind of electric heating heater that is used for output oil heating usefulness.

The heating furnace of oil exploitation mining site use at present mainly contains water batch heater and coil pipe heating furnace.Water batch heater is to add coil pipe in the water jacket, with heat transferred coil pipe inner fluid, belongs to indirect heating after water heats in the water jacket.This heating furnace is inapplicable for the oil well that yields poorly, intermittence is fuel-displaced, and 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.Fluid outes while advancing, at the short heating of residing time in furnace weak effect.Coil pipe heating furnace is that flame directly burns coil pipe, efficiency of heating surface height, but oil well when not fuel-displaced coil pipe burn high temperature, the coil pipe inner fluid can coking, stops up coil pipe and makes its damage.

The utility model purpose is: design a kind of oil electric heater, can realize flowing out after the oil preheating, handling safety, efficiency of heating surface height, effective.

This oil electric heater is that following mode realizes; In the Long Circle sealed tube body, oil well output oil enters from body one end bottom, flows out inboard wall of tube body dress superconduction radiator from other end top.Outer wall is adjustable temperature formula thermoelectric heating device, at heating element outer wrapping heat-barrier material, heat-barrier material is outward the topping shell.When oil well was fuel-displaced, electric heater passed to body and superconductor with electrical heat energy, and with the oil of heat transferred in it, the low temperature oil is entered by the bottom, and temperature rises to top after raising, and was flowed out by the top outlet.When if oil well is intermittently not fuel-displaced, electric heater is heated to a higher temperature with oil and keeps, and lightweight fraction and water evaporates flow out and promote fluid and continue to flow to oil gathering station in the oil under higher temperature.When so just keeping the stripper well winter low temperature intermittently fuel-displaced, prevent that oil low temperature from solidifying the blocking pipe problem that takes place.

These oil electric heater characteristics are: 1, realize flowing out heater after the oil preheating, improve heating-up temperature and add thermal effect.2, use superconductor and improve the thermal efficiency, 3, blocking pipe accident when preventing that oil well intermittently.4, the flames of anger of electrical heating constant temperature can not produce firing accident, work safety by the Yin Gaowen naked light indirectly.5, need not add water, simple and convenient management.

Below in conjunction with schematic diagram and embodiment this novel practical is described further.
