Embodiment Construction

[0015] specific implementation plan

[0016] exist figure 1 In the boiler device (1), high-temperature and high-pressure water vapor is generated by burning fuel oil, and the water vapor drives the power generation device (3) through the back-pressure steam turbine (2) to generate electric energy, and the exhaust steam of the back-pressure steam turbine enters the heat exchange device (4) Heat exchange is performed for the steps that need to be heated in the oil and gas gathering and transportation system. The water discharged from the heat exchange system is pressurized by the feed water pump (5) device and then enters the boiler device (1).

[0017] exist figure 2 Among them, the fuel pump delivers fuel oil (6) to provide fuel for the boiler unit (1), and the feed water pump (5) feeds water (9) into the boiler, and after heat exchange, high-temperature and high-pressure steam turbine inlet steam (10) is generated, and the back pressure steam turbine (2) The exhaust steam...

Abstract

The invention relates to an oil and gas gathering and transporting electricity and heat cogeneration system for substituting a heating furnace by utilizing a boiler, a backpressure type turbine and a heat exchange device and aims at mainly solving the problem that achieve energy gradient utilization cannot be achieved by adopting an existing single heating furnace and the exergetic efficiency is low in the oil and gas gathering and transporting process. The technical scheme is that the oil and gas gathering and transporting electricity and heat cogeneration system for substituting the heating furnace by utilizing the boiler, the backpressure type turbine and the heat exchange device comprises a boiler device, the backpressure type turbine, a generator, the heat exchange device and a water feed pump.

Description

technical field [0001] The invention belongs to an oil and gas gathering and transportation heating system that uses a boiler, a back pressure steam turbine and a heat exchange device instead of a heating furnace, and belongs to a new type of heat and power cogeneration system that replaces the oil and gas gathering and transportation production process transfer station for energy supply. Background technique [0002] Since most of the crude oil produced in my country's oil and gas fields is high-wax, high-freezing point, and high-viscosity crude oil, the oil and gas gathering and transportation process requires heating and transportation. Some oil and gas fields in my country use a single heating furnace to heat the process of oil and gas gathering and transportation. The heating system using heating furnace for oil and gas gathering and transportation consumes a lot of energy and has low energy utilization rate. [0003] The working process of the heating furnace is to co...
