The aforementioned solution solves the problems of existing desulfurization devices having a single desulfurization method for natural gas, resulting in poor desulfurization effect, complex structure, and cumbersome operation.

[0021] In this specific embodiment, one end of each of the multiple support rods 103 is fixedly connected to the base plate 101, and the other end of each of the multiple support rods 103 is fixedly connected to the housing 102. Both ends of the input pipe 104 pass through the housing 102 and are fixedly connected to it. One end of each of the multiple first branch pipes 106 is fixedly connected to the input pipe 104, and the other end of each of the multiple first branch pipes 106 is fixedly connected to the corresponding membrane separator 108. One end of each of the multiple second branch pipes 107 is fixedly connected to the output pipe 105, and the other end of each of the multiple second branch pipes 107 is fixedly connected to the corresponding membrane separator 108. The exhaust pipe 109 is fixedly connected to the upper surface of the housing 102, and the drain pipe 110 is fixedly connected to one side of the housing 102. The air intake assembly is fixedly connected to multiple membrane separators 108. The spray assembly is located inside the housing 102. In actual use, the air intake assembly delivers high-sulfur natural gas to multiple membrane separators 108. The membrane separators 108 use organic permeable membranes. Utilizing the selectivity of the membrane and the pressure difference on both sides, sulfides in the natural gas are separated. The sulfides are delivered to the output pipe 105 through multiple second branch pipes 107 and then output through the output pipe 105. The desulfurized natural gas is delivered to the input pipe 104 through multiple first branch pipes 106 and then input into the housing 102 through the input pipe 104. Then, the spray assembly sprays desulfurization liquid into the housing 102, thereby performing secondary desulfurization on the natural gas. The desulfurized natural gas is output from the exhaust pipe 109.

[0022] One end of each of the multiple connecting pipes 112 is fixedly connected to the air inlet pipe 111, and the other end of each of the multiple connecting pipes 112 is fixedly connected to the corresponding membrane separator 108. The heater 113 is disposed at one end of the air inlet pipe 111.

The heater 113 heats the natural gas, increasing its temperature, which is beneficial to mass transfer and separation efficiency in the membrane separation process.

[0023] Secondly, the spray pipe 114 penetrates the housing 102 and is fixedly connected to the housing 102. The multiple nozzles 115 are all fixedly connected to the spray pipe 114. The water supply component is located on the upper surface of the housing 102. In actual use, the desulfurization liquid is supplied to the spray pipe 114 through the water supply component and then sprayed into the interior of the housing 102 through the multiple nozzles 115.

[0024] Meanwhile, the water tank 116 is disposed on the upper surface of the tank body 102, one end of the water supply pipe 117 is fixedly connected to the water tank 116, the other end of the water supply pipe 117 is fixedly connected to the spray pipe 114, and the water pump 118 is disposed at one end of the water supply pipe 117. In actual use, the water pump 118 is started so that the desulfurization liquid in the water tank 116 is transported from the water supply pipe 117 to the spray pipe 114.

The multiple stirring plates 120 are all fixedly connected to the rotating roller 119. In actual use, the motor 121 is started, and the output end of the motor 121 drives the rotating roller 119 to rotate, causing the multiple stirring plates 120 to rotate, thereby making the natural gas and desulfurization liquid in the housing 102 fully mixed, thereby improving the desulfurization effect.

[0026] In this embodiment, a high-sulfur natural gas organic permeate membrane desulfurization device is used. Natural gas is input through the inlet pipe 111 and then transported to multiple membrane separators 108 via multiple connecting pipes 112. The natural gas is heated by the heater 113 to increase its temperature, which is beneficial for mass transfer and separation efficiency during membrane separation. The membrane separators 108 use organic permeate membranes and utilize the membrane's selectivity and pressure difference to separate sulfides from the natural gas. The sulfides are transported to the outlet pipe 105 via multiple second branch pipes 107 and then output through the outlet pipe 105. The desulfurized natural gas is then transported to the inlet pipe 104 via multiple first branch pipes 106. The desulfurized liquid is then input into the tank 102 through the input pipe 104. Then, the water pump 118 is activated, so that the desulfurization liquid in the water tank 116 is transported from the water supply pipe 117 to the spray pipe 114, and then sprayed into the tank 102 through multiple nozzles 115. At the same time, the motor 121 is started, and the output end of the motor 121 drives the rotating roller 119 to rotate, so that multiple stirring plates 120 rotate, thereby making the natural gas in the tank 102 fully mixed with the desulfurization liquid, thus performing secondary desulfurization on the natural gas. The desulfurized natural gas is output from the exhaust pipe 109. This method can effectively solve the problems of existing desulfurization devices having a single desulfurization method for natural gas, resulting in poor desulfurization effect, complex structure, and cumbersome operation.
