Description

Technical Field

[0001] This application relates to the field of gas-liquid separation technology, and in particular to a high-efficiency anaerobic tower gas-liquid separator device. Background Technology

[0002] Currently, with the rapid development of anaerobic technology for wastewater treatment, wastewater produces a large amount of moist biogas during anaerobic fermentation. Whether the biogas is ultimately used for combustion in a flare or as fuel for energy recovery in a boiler, it needs to be dried to remove its moisture. During the COD removal process in anaerobic fermentation, wastewater generates a large amount of biogas. In a closed anaerobic reactor, the biogas is collected through a three-phase separator. During the collection process, the biogas carries a large amount of moisture, approximately 1 to 1.5 times the biogas production, requiring preliminary gas-water separation at the top of the anaerobic reactor.

[0003] However, the existing anaerobic towers are equipped with gas-water separators that directly collect biogas containing water, resulting in low separation efficiency. When the biogas enters the flare or other biogas treatment systems, a high-consumption dehydration device is still required. Summary of the Invention

[0004] To address the problem of low separation efficiency in traditional steam-water separators, this invention provides a high-efficiency anaerobic tower steam-water separator device, comprising: a separator shell, an air inlet pipe, pore packing, and dehydration packing.

[0005] The separator housing has a hollow structure with an air outlet at the top and an air inlet at the bottom of the side wall. One end of the air inlet pipe is connected to the air inlet, and the other end is suitable for connecting to an air pump.

[0006] Both the pore packing and the dehydration packing are filled inside the separator housing, with the pore packing filling the bottom of the separator housing and the dehydration packing filling the top of the separator housing.

[0007] In one possible implementation, the pore filler is a sphere with through holes on its surface.

[0008] In one possible implementation, the pore filler is made of metal.

[0009] In one possible implementation, the pore packing includes a first pore packing and a second pore packing;

[0010] Both the first pore packing and the second pore packing are filled inside the separator housing, with the first pore packing located above the second pore packing;

[0011] The diameter of the first pore packing is smaller than that of the second pore packing, and the diameter of the through hole opened on the first pore packing is smaller than that of the through hole opened on the second pore packing.

[0012] In one possible implementation, the separator housing is a hollow, barrel-shaped structure.

[0013] In one possible implementation, the opening direction of the air inlet is tangent to the side wall of the separator housing.

[0014] In one possible implementation, the number of air inlets is two or more, and they are evenly spaced along the circumference of the separator housing.

[0015] In one possible implementation, the dehydration filler is a polyurethane filler.

[0016] In one possible implementation, a drain hole is provided at the bottom of the separator housing.

[0017] One possible implementation also includes support columns;

[0018] There are three support columns, which are vertically installed at the bottom of the separator housing;

[0019] The three support columns are arranged at equal intervals along the circumference of the separator housing.

[0020] The beneficial effects of the high-efficiency anaerobic tower gas-liquid separator device in this application embodiment are as follows: The high-efficiency anaerobic tower gas-liquid separator device has a simple structure and is easy to operate, which can effectively improve the efficiency of the anaerobic tower and reduce energy consumption. Specifically, the separator shell has a hollow structure with an air outlet at the top and an air inlet at the bottom of the side wall. One end of the air inlet pipe is connected to the air inlet, and the other end is suitable for connecting to the air pump. Pore packing and dehydration packing are filled inside the separator shell, so that biogas and liquid can be effectively separated in the separator, solving the problem that the biogas produced by traditional gas-liquid separators still has a high water content, and reducing the consumption generated by downstream biogas dehydration.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0030] like Figures 1-2As shown, the high-efficiency anaerobic tower steam-water separator device of this application embodiment includes: separator shell 3, air inlet pipe 1, pore packing and dehydration packing 6. The separator shell 3 is a hollow structure with an air outlet 2 at the top and an air inlet at the bottom of the side wall. One end of the air inlet pipe 1 is connected to the air inlet, and the other end is suitable for connecting to an air pump. The pore packing and dehydration packing 6 are both filled inside the separator shell 3, with the pore packing filling the bottom of the separator shell 3 and the dehydration packing 6 filling the top of the separator shell 3.

[0031] In this specific embodiment, the high-efficiency anaerobic tower gas-liquid separator of this application has a simple structure and is easy to operate, which can effectively improve the efficiency of the anaerobic tower and reduce energy consumption. Specifically, the separator shell 3 has a hollow structure with an air outlet 2 at the top and an air inlet at the bottom of the side wall. One end of the air inlet pipe 1 is connected to the air inlet, and the other end is suitable for connecting to the air pump. The pore packing and dehydration packing 6 are both filled inside the separator shell 3, so that the biogas and liquid inside the separator can be effectively separated, solving the problem that the biogas produced by traditional gas-liquid separators still has a high water content, and reducing the consumption generated by downstream biogas dehydration.

[0032] It should be noted that the high-efficiency anaerobic tower gas-liquid separator device of this application does not need to completely separate biogas from liquid; it is sufficient to achieve a large part of the separation between biogas and liquid.

[0033] In one specific embodiment, the porous packing is a sphere with through holes on its surface, which increases the contact area between the gas and the liquid and improves the separation efficiency.

[0034] In one specific embodiment, the pore packing is made of metal. Metal pore packing has high strength and corrosion resistance, which can effectively extend the service life of the packing.

[0035] In one specific embodiment, the pore packing includes a first pore packing 5 and a second pore packing 4. Both the first pore packing 5 and the second pore packing 4 are filled inside the separator housing 3, and the first pore packing 5 is located above the second pore packing 4. The diameter of the first pore packing 5 is smaller than that of the second pore packing 4, and the diameter of the through holes opened on the first pore packing 5 is smaller than that of the through holes opened on the second pore packing 4. The multi-layer packing design can further improve the separation efficiency, so that the gas and liquid can come into more complete contact.

[0036] Furthermore, in this specific embodiment, by setting two layers of stainless steel multi-porous metal balls of different specifications, the gas-water mixture is fully dehydrated by rising swirling flow. It first passes through large-pore packing material, and through the high thermal conductivity of the metal and the collision of pores, the water vapor components in the biogas are condensed into water droplets or fully intercepted. Then, it passes through smaller pore packing material by rising swirling flow.

[0037] In one specific embodiment, the separator housing 3 is a hollow, barrel-shaped structure, which provides a larger separation space and improves separation efficiency. Specifically, the separator housing 3 is approximately 20 meters in length.

[0038] In one specific embodiment, the air inlet is tangent to the side wall of the separator housing 3, allowing gas and liquid to enter the separator housing 3 more evenly and improving separation efficiency. Furthermore, the tangential arrangement of the air inlet to the side wall of the separator housing 3 allows the gas to rise in a swirling motion along the inner side wall of the separator housing 3, enabling sufficient collision and heat conduction during the gas's ascent, thus fully separating the moisture carried in the biogas.

[0039] In one specific embodiment, there are two or more air inlets, which are equally spaced along the circumference of the separator housing 3, so that gas and liquid enter the separator housing 3 more evenly and improve separation efficiency.

[0040] In one specific embodiment, the dehydration packing 6 is polyurethane packing, which has water absorption properties and excellent temperature resistance and corrosion resistance, and can effectively improve the stability and service life of the separator device.

[0041] In one specific embodiment, a drain hole is provided at the bottom of the separator housing 3 so that the separated liquid can be discharged in time, avoiding the accumulation of liquid in the separator housing 3 and affecting the separation efficiency.

[0042] In one specific embodiment, it also includes three support columns, which are vertically arranged at the bottom of the separator housing 3. The three support columns are equally spaced along the circumference of the separator housing 3 to provide better support and make the separator housing 3 more stable.

[0043] According to the above embodiment, by setting two layers of stainless steel multi-porous packing material of different specifications and a layer of small-pore polyurethane packing material, the gas-water mixture is fully dehydrated by rising swirling flow. First, it passes through large-pore metal balls, and through the high thermal conductivity of the metal and the collision of the pores, the water vapor components in the biogas are condensed into water droplets or fully intercepted. Then, it passes through the metal ball packing layer with smaller pores by rising swirling flow, and at the outlet, it is deeply dehydrated by polyurethane multi-porous spherical packing material, realizing full separation of gas and water and reducing the consumption of downstream processing.

[0044] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
