[0004] However, the above-mentioned disclosed solutions have the following shortcomings: In actual use, the adsorption effect of the adsorption plate structure decreases after long-term continuous use, and the adsorption plate containing mercury poses a toxic hazard during processing.

[0005] This invention proposes a natural gas mercury removal separator to solve the problem. Utility Model Content

[0006] The purpose of this invention is to process natural gas for mercury removal through a water circulation method, while simultaneously collecting the solid mercury oxide produced during the removal process, thus avoiding secondary pollution and overcoming the problems mentioned in the background art.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0008] A natural gas mercury removal separator includes a shell and an inlet pipe that penetrates its side. A water tank is connected inside the shell, and a cover plate is connected to the top of the water tank. The end of the inlet pipe away from the shell penetrates the cover plate and extends into the bottom of the water tank. An outlet pipe is connected to the top of the cover plate, and a sealing element is provided on the top of the cover plate at the joint between the cover plate and the inlet pipe. A circulation component is connected to the outer side of the shell to filter the water inside the water tank. By adding hydrogen peroxide to the water tank, the mercury in the natural gas can be oxidized to form mercury oxide precipitate. At the same time, the reaction heat in the water environment can avoid the combustion of natural gas. The collection of mercury oxide is easier than that of liquid elemental mercury, and the toxicity of mercury oxide is also reduced compared to elemental mercury.

[0009] Further defining the above technical solution, the circulation component includes a support plate connected to the outer side of the housing, a motor bracket connected to the top of the support plate, and a rotating motor connected to the motor bracket.

[0010] Further defining the above technical solution, the rotating motor's output end is connected to a rotating arm, the other end of the rotating arm is rotatably connected to a transmission arm, and the other end of the transmission arm is rotatably connected to a rotating component. The combination of the rotating arm and the transmission arm can effectively improve the transmission stability of the device, thereby realizing the vertical lifting and reciprocating sliding of the hydraulic plate. Combined with the one-way valve, the device can achieve a one-way liquid flow effect.

[0011] Further defining the above technical solution, the bottom of the rotating component is connected to a hydraulic plate, the top of the support plate is connected to a hydraulic housing, the inner wall of the hydraulic housing is slidably connected to the hydraulic plate, and a one-way inlet valve and a one-way outlet valve are symmetrically connected through the side of the hydraulic housing.

[0012] Further defining the above technical solution, the end of the one-way inlet valve away from the hydraulic housing is connected to an outlet pipe, which penetrates the side of the housing and connects to the side of the water tank. The end of the one-way outlet valve away from the hydraulic housing is connected to a return pipe, which penetrates the side of the housing and connects to the side of the water tank. The combination of the one-way outlet valve and the one-way inlet valve can effectively improve the one-way flow stability of the device and improve the liquid circulation stability of the device.

[0013] Further defining the above technical solution, the hydraulic housing is provided with an observation window on its side. The observation window is a transparent sealed glass plate, and a rotating bracket is connected to the outer side of the hydraulic housing. The observation window can intuitively display the content of solid mercury oxide remaining inside the hydraulic housing, thereby allowing the interior of the hydraulic housing to be cleaned according to actual usage requirements.

[0014] Further defining the above technical solution, the rotating bracket is rotatably connected to a rotating connector, and the other end of the rotating connector is connected to a rotating sealing plate. The hydraulic housing has an opening on its side, the rotating sealing plate covers the opening, a handle is connected to the outside of the rotating sealing plate, and a locking knob is provided on the side of the rotating bracket.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0026] Example 1: This example provides a natural gas mercury removal separator, such as... Figures 1-3As shown, the device includes a housing 1 and an air inlet pipe 2 that is connected through its side. A water tank 5 is connected inside the housing 1. A cover plate 3 is connected to the top of the water tank 5. The end of the air inlet pipe 2 away from the housing 1 passes through the cover plate 3 and extends into the bottom of the water tank 5. An air outlet pipe 4 is connected through the top of the cover plate 3. A sealing element 6 is provided on the top of the cover plate 3. The sealing element 6 is located at the joint between the cover plate 3 and the air inlet pipe 2. A circulation component 7 is connected to the outer side of the housing 1 for filtering the water inside the water tank 5.

[0027] The circulation component 7 includes a support plate 716 connected to the outer side of the housing 1. A motor bracket 701 is connected to the top of the support plate 716. A rotating motor 703 is connected to the motor bracket 701. A rotating arm 704 is connected to the rotating output end of the rotating motor 703. A transmission arm 705 is rotatably connected to the other end of the rotating arm 704. A rotating component 706 is rotatably connected to the other end of the transmission arm 705. A hydraulic plate 707 is connected to the bottom of the rotating component 706. A hydraulic housing 709 is connected to the top of the support plate 716. The inner wall of the hydraulic housing 709 is slidably connected to the hydraulic plate 707. A one-way inlet valve 708 and a one-way outlet valve 718 are symmetrically connected through the side of the hydraulic housing 709. By rotating the rotating arm 704 and the transmission arm 705 driven by the rotating motor 703, stable transmission of the lifting and sliding of the hydraulic plate 707 can be achieved. At the same time, the structure of the one-way inlet valve 708 and the one-way outlet valve 718 can ensure that the circulating water flows in one direction inside the hydraulic housing 709, thus ensuring the stability of the water circulation filtration and interception effect of this device.

[0028] One end of the one-way inlet valve 708 away from the hydraulic housing 709 is connected to an outlet pipe 702. The outlet pipe 702 passes through the side of the housing 1 and is connected to the side of the water tank 5. One end of the one-way outlet valve 718 away from the hydraulic housing 709 is connected to a return pipe 717. The return pipe 717 passes through the side of the housing 1 and is connected to the side of the water tank 5.

[0029] The hydraulic housing 709 has an observation window 710 on its side, which is a transparent sealed glass plate. A rotating bracket 714 is connected to the outer side of the hydraulic housing 709.

[0030] The specific working principle is as follows: the interception net set inside the one-way outflow valve 718 can achieve the interception effect of solid mercury oxide. As the mercury oxide is carried by the circulating water, it is intercepted and retained inside the hydraulic housing 709, thus ensuring the cleanliness of the water tank 5.

[0031] Example 2: This example provides a natural gas mercury removal separator, such as... Figures 1-3As shown, a rotating bracket 714 is rotatably connected to a rotating connector 713, and a rotating sealing plate 711 is connected to the other end of the rotating connector 713. An opening is provided on the side of the hydraulic housing 709, and the rotating sealing plate 711 covers the opening. A handle 712 is connected to the outer side of the rotating sealing plate 711. A sealing ring is provided on the outer side of the hydraulic plate 707, and the sealing ring contacts and presses against the inner wall of the hydraulic housing 709. An opening is provided at the top of the hydraulic housing 709. A locking knob 715 is provided on the side of the rotating bracket 714. The locking knob 715 can lock the rotation of the rotating connector 713, thereby fixing the rotating sealing plate 711. The locking knob 715 ensures that the device facilitates cleaning of the inside of the hydraulic housing 709 while ensuring a tight seal during normal use through the rotating sealing plate 711, thus preventing hydraulic leakage.

[0032] The specific working principle is as follows: This device can effectively improve the stability of mercury removal processing of natural gas. When this device is in use, the inlet pipe 2 of this device is connected to the natural gas source, and the outlet pipe 4 of this device is connected to the downstream equipment, which ensures the stable connection of this device and reduces the difficulty of combining and using this device.

[0033] After the device is connected, natural gas enters the device through the inlet pipe 2. The inverted U-shaped structure of the inlet pipe 2 guides the natural gas to the bottom of the water tank 5, ensuring that the hydrogen peroxide and natural gas inside the water tank 5 can fully contact each other. This allows the mercury in the natural gas to form solid mercury oxide under the oxidation of hydrogen peroxide, which then precipitates at the bottom of the water tank 5. The natural gas discharged from the top outlet pipe 4 no longer contains mercury vapor.

[0034] The circulation component 7 facilitates the collection of mercuric oxide precipitate inside the water tank 5. After the device has been in use for a period of time, the rotating motor 703 is started, which drives the rotating arm 704 to rotate. This, in turn, enables the hydraulic plate 707 to vertically lift and reciprocate linearly through the transmission arm 705. Furthermore, the combination of the hydraulic housing 709 with the one-way inlet valve 708 and the one-way outlet valve 718 achieves the effect of one-way circulation of hydrogen peroxide inside the water tank 5. The interception net installed inside the one-way outlet valve 718 can intercept solid mercuric oxide inside the hydraulic housing 709 during the water circulation process, thereby ensuring the cleanliness of the water tank 5.

[0035] After the rotating motor 703 has been running for a period of time, a portion of solid mercury oxide remains inside the hydraulic housing 709. At this time, by rotating the locking knob 715, the rotating connector 713 can rotate relative to the rotating bracket 714, thereby achieving the effect of opening the rotating sealing plate 711. This makes it easier for staff to clean the inside of the hydraulic housing 709 while reducing the difficulty of recovering the solid mercury oxide.

[0036] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
