Embodiment 1
[0021] Such as figure 1 As shown, the device of the present invention includes a vertical heating furnace 1, a control cabinet 2 and an integrated skid body 3, an electric control valve 8 is installed in the integrated skid body 3, and one end of the electric control valve 8 is connected to the gas outside the integrated skid body 3 The inlet is connected, and the other end of the electric regulating valve 8 is connected with the detection device, and the detection device is connected with the negative pressure injection burner 20 in the vertical heating furnace 1; the detection device is composed of a parallel first detection channel and a second detection channel The first detection channel is connected in sequence by the first stop valve 9, the first solenoid valve 10 and the second stop valve 11; the second detection channel is connected by the third stop valve 14, the second solenoid valve 15 and the fourth The cut-off valve 16 is connected sequentially; the electric cont...
Embodiment 2
[0024] Such as figure 1 As shown, a ball valve 4 is installed outside the integrated skid 3, and a first pressure gauge 5, a filter 6, a pressure regulating valve 7, a second pressure gauge 12 and a flame arrester 16 are installed inside the integrated skid 3; A ball valve 4, a first pressure gauge 5, a filter 6 and a pressure regulating valve 7 are sequentially connected between the gas inlet and the electric regulating valve 8; a second pressure gauge is sequentially connected between the detection device and the negative pressure injection burner 20. Table 12 and flame arrester 16.
[0025] Because associated gas is a by-product of oil extraction, its pressure is unstable and often contains a lot of water, so it needs to be treated before burning. Remove impurities from the gas through the ball valve 4 and separate part of the water; then enter the pressure regulating valve 7 to adjust the gas pressure to within 100kPa. The flame arrester 20 prevents the fire from flashin...
Embodiment 3
[0027] Such as figure 1 As shown, the control cabinet 2 is wirelessly controlled by a remote controller 22 . 1 is also equipped with water temperature sensor 17, flame probe 18 and electronic lighter 19 in the vertical heating furnace, and water temperature sensor 17, flame probe 18 and electronic lighter 19 are all electrically connected with control cabinet 2. The control cabinet 2 is also electrically connected with an audible and visual alarm device 21 . The control cabinet 2 is also provided with a water temperature indicator light and a fault indicator light.
[0028] Control electronic lighter 19 by remote controller 22, can realize remote ignition. The water temperature sensor 17 is interlocked with the control valve 8 through the control cabinet 2, automatically adjusts the fuel gas supply according to the set feed water temperature, adjusts the size of the flame, and ensures that the water supply temperature is constant. When the water temperature is overheated, t...
