Embodiment approach 1

[0039] Embodiment 1 is the steam generating device related to the present invention, in combination with the attached figure 1 and figure 2 illustrate.

[0040] figure 1 Among them, the water pump 2, the electric heater 1, the one-way valve 3, the first on-off valve 4, the condenser 5, and the back pressure valve 6 are connected in sequence through pipelines, and the pipeline between the first on-off valve 4 and the electric heater 1 A steam output bypass is set on the road, and a second on-off valve 7 is set on the steam output bypass. The electric heating wire 13 on the electric heater 1 is connected to the power controller 8, and the power controller 8 is connected to the power supply through the v head and the u head; the output port of the electric heater 1 is provided with a four-way joint, and the p port of the four-way joint is set for pressure sensor, the q port is provided with a temperature sensor.

Embodiment approach 2

[0047] Embodiment 2 is a method of using the steam generating device of Embodiment 1 to generate steam with a certain degree of dryness, combined with the attached figure 1 , 2 , 3 instructions.

[0048] First set the flow rate and pressure of the pump 2 and the pressure of the back pressure valve 6, connect the power supply of the v head and the u head, and control the power of the input electric heating wire 13 through the power controller 8; the water in the heating water pipe 11 absorbs heat, and the temperature increases , The volume expands, and the pressure increases accordingly. The pressure of the output port is monitored through the p port, and the temperature of the outlet is monitored through the t port. Under the action of the back pressure valve, the pressure of the water remains constant and finally reaches an equilibrium state.

[0049] Then increase the input power of the electric heating wire 13 by the power controller 8, monitor the pressure and temperature...

Embodiment approach 3

[0055] Embodiment 3 is a method for generating superheated steam using the steam generating device of Embodiment 1, combined with the attached figure 1 , 2 , 3 instructions.

[0056] Firstly, the same method as Embodiment 2 will be used to obtain saturated steam with a dryness of 100%. Through the power controller 8 to continue to increase the output power, the steam at the output port will get more heat, thereby transitioning from saturated steam to superheated steam. During the power increase process, the temperature of the superheated steam will also continue to rise. When the steam temperature is T2, the input power is P4, and the required superheated steam can be obtained by stabilizing the input power at P4 through the power controller.

Abstract

The invention provides a steam generation device which can generate steam with pressure, temperature, flow and dryness adjustable and the invention provides a dryness adjustment method. By adjusting flow of a water pump, the output flow speed of the steam can be conveniently adjusted, the pressure value of the steam can be kept constant under the action of a back pressure valve, and accordingly the steam with constant pressure is generated. By means of matching of the water pump, an electric heating wire and the back pressure valve, the steam with flow, pressure and temperature adjustable can be generated, and the output steam can be monitored through a temperature sensor and a pressure sensor.

Description

technical field [0001] The invention relates to the technical field of test instruments, in particular to a steam generating device and a method for adjusting dryness. Background technique [0002] In the simulation test of oil recovery process, steam with adjustable parameters such as pressure, temperature, flow rate and dryness is needed to simulate the steam flooding oil recovery process. The Chinese utility model patent with the authorized announcement number CN 2771651Y discloses a high-pressure saturated steam generator , through the use of the pressure relay, the effect of steam can be injected when a certain pressure is reached, but it cannot produce continuous steam with adjustable flow; in addition, the boiler heating method is adopted, the boiler body is greatly affected by the environment, and the stability is relatively high Poor, the controllability of the system is not high; it is difficult to generate continuous steam with adjustable parameters such as pressu...
