DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment. Obviously, the described embodiment is part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figs. 1 to 4 The utility model provides a technical scheme: a torch condensate recovery device, using a burning torch body 100, further comprising

[0027] An accelerating gas-liquid separation tank 200, the accelerating gas-liquid separation tank 200 comprises a gas-liquid tank body 210 and a gas-liquid assembly 220, the gas-liquid tank body 210 comprises a tank body 211, the tank body 211 is respectively communicated with an input pipe 213 and an output pipe 214 at both ends, the gas-liquid assembly 220 comprises a first liquid separation plate 221 and a second liquid separation plate 222, the first liquid separation plate 221 and the second liquid separation plate 222 are installed in the interior of the gas-liquid tank body 210 staggered, and the first liquid separation plate 221 and the second liquid separation plate 222 are located between the input pipe 213 and the output pipe 214; a backfire prevention mechanism 300, the backfire prevention mechanism 300 comprises a water seal tank 310 and a communication assembly 320, the water seal tank 310 is communicated with the gas-liquid tank body 210, one side of the water seal tank 310 is communicated with the torch body 100 through the communication assembly 320, and the staggered first liquid separation plate 221 and the second liquid separation plate 222 are like layer upon layer of filter screens, which intercept and divert the high-speed flowing torch gas multiple times, so as to promote gas-liquid separation.

[0028] Valves and other necessary components are arranged on the pipelines of the accelerating gas-liquid separation tank 200 and the backfire prevention mechanism 300.

[0029] The bottom of the tank body 211 is fixedly connected with support legs 212 at both ends, the support legs 212 are arranged in an isosceles trapezoidal shape, and provide a solid foundation for normal work of the internal precise gas-liquid separation component, greatly reducing problems such as component wear and tear, gas-liquid separation effect decline caused by device displacement and shaking, and the like, the flare condensate tank is provided with a condensate pump, and the pump is manually started and automatically stopped in real time according to the liquid level in the tank, so that the condensate is pressurized and sent out of the flare system in a timely manner, and the liquid level is controlled within the range required by the normal process.

[0030] One end of the input pipe 213 is in communication with an external vent gas input source, the other end of the input pipe 213 penetrates one end of the top of the tank body 211, and one end of the output pipe 214 penetrates the other end of the top of the tank body 211. The flare gas from the external vent gas input source usually has a certain flow rate and pressure, and the input pipe 213 is penetrated and connected from one end of the top of the tank body 211, so that the space height inside the tank body can be utilized to provide a sufficient “buffer” area for the gas after entering the tank body 211, so as to avoid the condensate from splashing and re-mixing due to direct impact of the gas on the bottom, which is not conducive to gas-liquid separation. Similarly, the output pipe 214 is penetrated and led out from the other end of the top, on the one hand, to facilitate connection with subsequent water seal tank 310 and the like, and to build a coherent gas treatment process; on the other hand, to ensure that the gas that has been preliminarily treated in the tank body 211 can flow out smoothly and stably, and to reduce gas stagnation and pressure fluctuations caused by unreasonable pipeline layout, thereby improving the operating efficiency of the entire device.

[0031] The end of the input pipe 213 and the output pipe 214 located inside the tank body 211 is arranged in an arc shape, the end of the input pipe 213 and the output pipe 214 is arranged in parallel with the top of the tank body 211, and the end of the input pipe 213 and the output pipe 214 is respectively in communication with a gas guide nozzle 216 installed thereon, the gas guide nozzle 216 is in the shape of a horn, and the two gas guide nozzles 216 are arranged correspondingly. The end of the output pipe 214 away from the tank body 211 is in communication with a communication pipe 215 installed thereon, the other end of the communication pipe 215 is in communication with the water seal tank 310, and the horn-shaped gas guide nozzle 216 has the dual functions of pressure expansion and flow guiding, which can uniformly disperse the entering high-speed gas flow, reduce the gas flow rate, and avoid impact damage to the internal components of the tank body 211 caused by excessively high local flow rate; at the same time, when the gas flows out, it can also ensure smooth transition of the gas, reduce pressure loss, and ensure that the connected components can receive stable gas.

[0032] The middle part of the input pipe 213 is communicated and provided with a cyclone separator 217, which is installed on the top of the tank body 211. When the flare gas just enters from the external discharge gas input source, it is often mixed with liquid particles of different sizes. If the larger particles directly enter the inside of the tank body 211, not only the working burden of the subsequent first liquid distribution plate 221 and the second liquid distribution plate 222 is increased, but also the liquid is re-atomized due to impact and other reasons, which affects the separation effect. The cyclone separator 217 utilizes the principle of centrifugal force to throw these larger particle liquids to the wall before the gas enters the tank body 211, and makes them flow along the wall to the collection area pre-provided at the bottom of the tank, thereby realizing the preliminary "coarse filtration" of the flare gas, laying a good foundation for the subsequent fine gas-liquid separation process, and greatly improving the gas-liquid separation efficiency and reliability of the entire device.

[0033] The first liquid distribution plate 221 and the second liquid distribution plate 222 are uniformly distributed with first liquid distribution holes 223 and second liquid distribution holes 224. The first liquid distribution holes 223 and the second liquid distribution holes 224 are both wavy, and the first liquid distribution holes 223 and the second liquid distribution holes 224 are both inclined. The second liquid distribution holes 224 are arranged in axial symmetry with the first liquid distribution holes 223, and the liquid is more easily separated from the gas under the action of inertia. The inclination further utilizes the gravity factor, so that the separated liquid can quickly flow to the bottom of the tank body 211 along the inclined direction.

[0034] The first liquid distribution plate 221 and the second liquid distribution plate 222 are provided with auxiliary mesh plates 225 on the side close to the output pipe 214. The auxiliary mesh plates 225 are provided in plurality, and the plurality of auxiliary mesh plates 225 are fixedly connected with the inner top of the tank body 211.

[0035] The communication assembly 320 includes a first connecting pipe 321, a second connecting pipe 322, a third connecting pipe 323, a fourth connecting pipe 324, a fifth connecting pipe 325, a sixth connecting pipe 326 and a seventh connecting pipe 327. One end of the first connecting pipe 321, the second connecting pipe 322, the third connecting pipe 323, the fourth connecting pipe 324, the fifth connecting pipe 325, the sixth connecting pipe 326 and the seventh connecting pipe 327 is communicated with the water seal tank 310 respectively, and the other end is communicated with the flare body 100 respectively. The diameters of the first connecting pipe 321, the second connecting pipe 322, the third connecting pipe 323, the fourth connecting pipe 324, the fifth connecting pipe 325, the sixth connecting pipe 326 and the seventh connecting pipe 327 gradually increase. The first connecting pipe 321, the second connecting pipe 322, the third connecting pipe 323, the fourth connecting pipe 324, the fifth connecting pipe 325, the sixth connecting pipe 326 and the seventh connecting pipe 327 enter the corresponding seven-stage flare burners, which are used as protection gas and flare smoke elimination: not only protect the flare burners and smoke elimination, but also increase the safety of the equipment, while providing pressure equipment insulation in three ways.

[0036] Working principle: The flare gas from the external flare gas input source enters the acceleration gas-liquid separation tank 200 through the input pipe 213. The arc-shaped design of the end of the input pipe 213 and the horn-shaped gas guide nozzle 216 guide the gas to enter the tank body 211 smoothly, avoiding the gas directly impacting the tank wall to cause local pressure to be too high or to erode the components. At the same time, the cyclone separator 217 in the middle of the input pipe 213 uses the principle of centrifugal force to throw the larger particles of condensate in the flare gas to the wall and flow down to the tank bottom along the wall, realizing preliminary separation.

[0037] The flare gas entering the tank body 211 then flows through the first and second liquid separation plates 221 and 222 arranged in a staggered manner. When the gas passes through the first and second liquid separation holes 223 and 224 arranged in a wave shape and inclined, the flow direction of the gas changes constantly. The condensate cannot follow the rapid change in direction of the gas due to inertia and gradually settles to the tank bottom under the action of gravity. Moreover, the second liquid separation hole 224 is arranged in axial symmetry with the first liquid separation hole 223, making the flow path of the gas between the liquid separation plates more complex and further promoting gas-liquid separation. The multiple auxiliary mesh plates 225 near the output pipe 214 can capture some small liquid droplets to prevent them from being carried out by the gas flow, ensuring that the condensate content in the discharged gas is as low as possible.

[0038] The gas after preliminary treatment by the acceleration gas-liquid separation tank 200 passes through the output pipe 214 and the connecting pipe 215 into the water seal tank 310. The water in the water seal tank 310 forms a liquid seal. When the flare system is operating normally, the gas flows from the gas phase space above the water seal tank 310 through the connecting assembly 320 to the flare body 100 for combustion. If backfiring occurs, when the flame propagates in the reverse direction to the water seal tank 310, the water layer in the water seal tank 310 can effectively prevent the flame from continuing to propagate in the reverse direction, cutting off the connection between the flame and the upstream device, and ensuring the safety of the system.

[0039] The connecting assembly 320 includes first, second, third, fourth, fifth, sixth, and seventh connecting pipes 321, 322, 323, 324, 325, 326, and 327 with diameters gradually increasing. According to the flow demand of the flare gas under different working conditions, the control system can selectively open connecting pipes of different diameters to adapt to the flow changes of the flare gas. In low-flow working conditions, small-diameter connecting pipes (such as the first connecting pipe 321) are opened to ensure that the gas has a suitable flow rate and pressure in the burner of the flare body 100, realizing stable combustion. In high-flow working conditions, large-diameter connecting pipes are gradually opened to ensure that the flare gas can be timely and smoothly delivered to the burner for combustion, maintaining the efficient operation of the entire flare system.

[0040] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
