Description

Technical Field

[0001] This utility model relates to the field of microalgae carbon fixation technology, and in particular to a flue gas transmission hydrophobic device. Background Technology

[0002] In microalgae carbon fixation processes, column-type photobioreactors are key equipment for algal photosynthesis and carbon fixation. The flue gas supplied to the reactor directly affects algal growth and carbon fixation efficiency.

[0003] However, the flue gas transported often contains moisture and impurities. Existing hydrophobic systems cannot remove these substances, causing them to enter the reactor with the flue gas, damaging the algae growth environment, interfering with photosynthesis, and thus affecting the normal growth of algae, which restricts the stable and efficient operation of the microalgae carbon fixation process.

[0004] Therefore, it is necessary to improve the existing flue gas transmission hydrophobic devices. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a flue gas transmission and drainage device that requires no power and automatically discharges pollutants by utilizing the high potential energy of the water level, separating water, impurities and flue gas.

[0006] To achieve the above-mentioned technical effects, the technical solution of this utility model is as follows: a flue gas transmission hydrophobic device, comprising a main pipe for transmitting flue gas to a photobioreactor, a hydrophobic unit disposed below the main pipe, the hydrophobic unit comprising a first branch pipe communicating with the main pipe and a water storage tank communicating with the first branch pipe, the water storage tank being disposed below the first branch pipe, and a first valve being disposed between the first branch pipe and the water storage tank; further comprising a water collection device, a second branch pipe communicating with the water storage tank and the water collection device, the second branch pipe being disposed of with a second valve.

[0007] According to one embodiment of the present invention, the side wall of the moisture storage tank is sealed with an observation window, which is disposed adjacent to the top of the moisture storage tank.

[0008] According to one embodiment of the present invention, the upper wall of the water storage tank is provided with a water inlet, and the water inlet is detachably provided with a flange, and the water inlet is used to connect a water pipe for cleaning its inner cavity.

[0009] According to one embodiment of the present invention, a drainage pipe is provided at the bottom of the water storage tank, and a guide slope is provided between the water storage tank and the drainage pipe.

[0010] According to one embodiment of the present invention, the surface of the guide slope is provided with an anti-stick coating.

[0011] According to one embodiment of the present invention, the drainage pipe is disposed above the second valve, and a filter screen is detachably disposed in the drainage pipe.

[0014] According to one embodiment of the present invention, at least two hydrophobic units are provided along the extension direction of the main pipe.

[0015] The advantages and beneficial effects of this utility model are as follows: The flue gas transmission water-draining device of this utility model has a reasonable structure. By setting a water-draining unit below the main pipe, when the flue gas is slowly transmitted in the main pipe, the moisture and impurities in the flue gas will automatically fall into the first branch pipe under the action of gravity, and then fall into the water storage tank, thereby achieving the purpose of smooth discharge of moisture and impurities in the flue gas, and thus preventing moisture and impurities in the flue gas from entering the column photobioreactor and affecting the normal growth of algae.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0019] like Figure 1-6 As shown, the flue gas transmission hydrophobic device of the embodiment includes a main pipe 1 for transmitting flue gas to the photobioreactor. A hydrophobic unit is provided below the main pipe 1. The hydrophobic unit includes a first branch pipe 2 connected to the main pipe 1 and a water storage tank 3 connected to the first branch pipe 2. The water storage tank 3 is located below the first branch pipe 2. A first valve 21 is provided between the first branch pipe 2 and the water storage tank 3. The device also includes a water collection device. A second branch pipe 4 is provided between the water storage tank 3 and the water collection device. A second valve 41 is provided on the second branch pipe 4.

[0020] With this design, automatic separation is achieved without additional power consumption: through vertical layout, gravity is used to allow moisture and impurities in the flue gas to naturally settle to the first branch pipe and then fall into the temporary storage box.

[0021] Precise separation of moisture and impurities ensures microalgae growth: The hydrophobic unit specifically catches moisture and impurities in the flue gas, preventing them from entering the photobioreactor with the flue gas, thus ensuring the normal growth of microalgae and the stable and efficient operation of the carbon fixation process.

[0022] Moisture is collected centrally for easy subsequent treatment: The temporary storage tank is connected to the moisture collection device through the second branch pipe, which can centrally collect the separated moisture for easy subsequent compliant discharge or reuse.

[0023] According to one embodiment of the present invention, the side wall of the moisture storage tank 3 is sealed with an observation window 31, and the observation window 31 is disposed adjacent to the top of the moisture storage tank 3.

[0024] This design allows for intuitive monitoring of water levels and prevents water from overflowing: the observation window allows direct observation of the real-time water level in the water storage tank, and because the observation window is adjacent to the top of the storage tank, it can accurately determine the critical state. Once the water level is found to be too high, the second valve can be opened in time to prevent water from overflowing from the top of the storage tank.

[0025] To ensure flue gas sealing and avoid resource waste and safety hazards: The observation window adopts a "sealed setting" to prevent flue gas in the moisture storage box from leaking out of the observation window gaps.

[0026] According to one embodiment of the present invention, the upper wall of the water storage tank 3 is provided with a water inlet 32, and the water inlet 32 ​​is detachably provided with a flange 321. The water inlet 32 ​​is used to connect a water pipe for cleaning its inner cavity.

[0027] This design efficiently removes residue from the inner cavity, preventing blockages and functional failures: The moisture storage tank is the core component for temporarily storing moisture and impurities in flue gas. After long-term use, sticky impurities and fine particles easily adhere to the tank walls or settle at the bottom. By connecting a water pipe through the water inlet, clean water can be directly introduced into the inner cavity of the storage tank to flush key areas such as the tank walls and guide slopes, thoroughly removing residual impurities.

[0028] Balancing sealing and ease of maintenance without affecting flue gas transmission: The water inlet is equipped with a detachable flange: During daily use, the flange is installed on the water inlet to tightly seal the interface and prevent flue gas in the water storage tank from leaking out of the water inlet; when cleaning is required, only the flange needs to be removed to connect the water pipe, without disassembling the entire structure of the storage tank, making the operation simple and quick, and greatly reducing maintenance time and labor costs.

[0029] According to one embodiment of the present invention, a drainage pipe 5 is provided at the bottom of the water storage tank 3, and a guide slope 6 is provided between the water storage tank 3 and the drainage pipe 5.

[0030] This design guides waste to concentrate and avoids bottom sedimentation: the guide slope, based on the "slope design," can actively guide water and impurities in the temporary storage box to flow towards the drainage pipe, solving the problem of waste accumulation on the flat bottom of the temporary storage box.

[0031] According to one embodiment of the present invention, the surface of the guide slope 6 is provided with an anti-stick coating.

[0032] This design prevents impurities from adhering and ensures smooth flow of flue gas. Impurities in the flue gas, if in direct contact with the surface of a regular guide slope, tend to stick to the slope due to adhesion or static electricity. The anti-stick coating forms a smooth, non-adhesive barrier on the guide slope surface, allowing moisture and impurities to remain in a flowing state and preventing them from accumulating on the slope. This ensures the guide slope continuously guides waste towards the drainage pipe without affecting sewage discharge efficiency. The anti-stick coating can be a polytetrafluoroethylene coating, etc.

[0033] According to one embodiment of the present invention, the drainage pipe 5 is disposed above the second valve 41, and a filter screen 7 is detachably disposed in the drainage pipe 5.

[0034] This design reduces maintenance difficulty and saves costs: the filter screen is detachable, allowing for easy removal and cleaning or replacement without disassembling the entire drainage pipe structure.

[0035] Protect the second valve to reduce subsequent processing pressure.

[0036] According to one embodiment of the present invention, the side wall of the drainage pipe 5 is provided with a slot 51, the filter screen 7 is slidably connected to the slot 51, and the filter screen 7 is provided with a sealing plate 71 for closing the opening of the slot 51.

[0037] This design significantly reduces the difficulty of filter maintenance and improves operational efficiency: the filter screen and the slot on the side wall of the drain pipe are connected by a sliding connection, eliminating the need to disassemble the entire structure of the drain pipe; when the filter screen's filter chamber accumulates a lot of sticky impurities or large pieces of impurities, simply pull the filter screen directly along the slot to remove it, and after cleaning or replacement, push it back into place along the slot.

[0038] The slot is tightly sealed to prevent smoke leakage and impurities from entering: the sealing plate equipped with the filter screen can precisely seal the slot opening.

[0039] According to one embodiment of the present invention, the filter screen 7 is provided with a filter chamber 72 for temporarily storing sticky impurities and large impurities.

[0040] This design concentrates specific impurities to prevent clogging of the filter and pipes: sticky impurities in flue gas are the main risk source for pipe blockage. These impurities may directly adhere to the filter surface, clogging the filter pores, or enter the drainage pipe with the water flow and become stuck on the pipe wall and valves. The filter chamber can specifically contain these two types of impurities within its body, preventing them from spreading to downstream pipes and ensuring the smooth operation of the drainage and condensate drainage system.

[0041] According to one embodiment of the present invention, at least two hydrophobic units are provided along the extension direction of the main pipe 1.

[0042] This design covers the entire main pipeline, improving the efficiency of water and impurity separation: at least two drainage units are set up along the extension direction of the main pipeline, which can achieve "segmented coverage" of the entire main pipeline, allowing water and impurities in different sections to settle into the corresponding drainage units nearby, greatly reducing omissions and improving the overall separation efficiency.

[0043] Improve system fault tolerance and ensure uninterrupted hydrophobic function: If only one hydrophobic unit is set up, once it fails, the entire hydrophobic system will fail, and water and impurities will directly enter the reactor.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
