[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 3As shown, the Brownian gas-liquid seal anti-backfire device of this embodiment includes an air inlet pipeline 1, a water storage tank unit 2, a reflux tank unit 3, a flow regulating valve 4 and an air outlet pipeline 5 which are sequentially connected along the Brownian gas conveying direction. The water storage tank unit 2 includes a water storage tank body 201 and a vertical connecting pipe 202. The output end of the air inlet pipeline 1 is connected to the bottom of the water storage tank body 201. The reflux tank unit 3 includes a reflux tank body 301 and a reflux pipe 302. The vertical connecting pipe 202 is connected to the reflux tank body 301 through an extension pipe 6. The extension pipe 6 is penetrated in the reflux tank body 301 and extends to the bottom of the reflux tank body 301. The output end of the reflux pipe 302 is connected to the water storage tank body 201. The Brownian gas-liquid seal anti-flashback device comprises a water storage tank unit 2, a reflux tank unit 3 and a flow regulating valve 4. The water storage tank unit 2 is used to isolate the gas outlet pipeline 5 from the gas inlet pipeline 1 to prevent the flashback flame from flowing back to the gas source end, thereby improving safety. At the same time, the flow regulating valve 4 can control the stable delivery of the Brownian gas in the device, thereby having strong reliability and good operating stability.

[0022] Preferably, the outer side of the water storage tank body 201 is connected to a liquid level pipe 7, and a liquid level sensor 8 is provided on the liquid level pipe 7. In this embodiment, the liquid level pipe 7 and the water storage tank body 201 form a communicating vessel, so the liquid level in the liquid level pipe 7 is level with the liquid level in the water storage tank body 201. When the liquid level sensor 8 detects that the liquid level is too low, a control signal is sent to stop the air intake pipeline 1 from intake and prompt the staff to add water so that the liquid level rises to a normal height.

[0023] Preferably, the outer side of the liquid level tube 7 is connected to a water level observation tube 9. In this embodiment, the water level observation tube 9 and the liquid level tube 7 form a communicating vessel, and the staff can directly observe the liquid level in the water storage tank 201 through the water level observation tube 9 and intuitively understand the operation of the device.

[0024] Preferably, the reflux tank body 301 is filled with a stainless steel wire 303 for gas-liquid separation. In this embodiment, the reflux tank body 301 is filled with a stainless steel wire 303. Since the extension tube 6 extends to the bottom of the reflux tank body 301, the flow direction of the Brownian gas in the reflux tank body 301 is from bottom to top. The fine droplets entrained in the Brownian gas will condense when passing through the stainless steel wire 303. The droplets flow downward along the fine wire under the action of gravity, while continuing to absorb the droplets entrained in the condensed gas. The droplets accumulate at the bottom of the reflux tank body 301 and flow back to the water storage tank body 201 through the reflux pipe 302, thereby realizing the gas-liquid separation of the Brownian gas.

[0025] Preferably, the ends of the vertical connecting pipe 202 and the reflux tank body 301 are both provided with explosion-proof discs 10. In this embodiment, when the Brownian gas flashback phenomenon occurs, the explosion-proof discs 10 can explode at a specified temperature and pressure to release the pressure, thereby preventing the water storage tank unit 2 and the reflux tank unit 3 from being damaged by overpressure, thereby improving safety.

[0026] Preferably, the reflux tank 301 is connected to the flow regulating valve 4 through the connecting pipe 11, and a pressure gauge 12 is provided on the connecting pipe 11. In this embodiment, the pressure gauge 12 is used to detect the pressure in the connecting pipe 11, so that the staff can intuitively understand the operation of the device. When the pressure in the pipe floats, the pressure gauge 12 feeds back the signal to the flow regulating valve 4 and adjusts the Brownian gas delivery flow, effectively improving the operation stability.

[0027] Preferably, the air inlet pipeline 1 is provided with a first valve body 101 for controlling the on-off of the air path, and the air outlet pipeline 5 is provided with a second valve body 501 for controlling the on-off of the air path, and the first valve body 101 and the second valve body 501 are respectively electrically connected to the pressure gauge 12. In this embodiment, when the explosion-proof disc 10 on the vertical connecting pipe 202 or the explosion-proof disc 10 on the reflux tank 301 explodes, the pressure in the connecting pipe 11 decreases rapidly, and the pressure gauge 12 sends a control signal after detecting the abnormal pressure in the pipe, so that the first valve body 101 and the second valve body 501 are closed at the same time. After the device empties the Brown gas, the staff can perform troubleshooting and repair and maintenance on the device.

[0028] It should be noted that if Figure 3 The figure shows a schematic diagram of the application of Brown's gas-liquid seal anti-flashback device in the anti-flashback system, in which three sets of Brown's gas-liquid seal anti-flashback devices are installed in parallel, and the air inlet pipeline 1 transports Brown's gas to three sets of water tank units 2 through branch pipelines, and three sets of air outlet pipelines 5 transport the Brown's gas to the next component.

[0029] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
