Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid mixing systems, and particularly relates to a sewage gas-liquid fusion reactor and a gas-liquid mixing system. Background Art

[0002] The current sewage gas-liquid fusion reactor is used to mix oxygen-containing gas with water to increase the oxygen content in the water. Specifically, the gas is retained at the top of the sewage gas-liquid fusion reactor, and the fusion of water and oxygen is completed by continuously introducing water. However, the existing sewage gas-liquid fusion reactor can only mix oxygen-containing gas with clean water because its structure determines that the mixed sewage is prone to blockage. However, in actual use, such as in the aquaculture industry, most of the water is sewage. Therefore, it is necessary to design a sewage gas-liquid fusion reactor that can reduce blockage. Summary of the Utility Model

[0003] To solve the problem that the current sewage gas-liquid fusion reactor is prone to blockage, the utility model provides a sewage gas-liquid fusion reactor and a gas-liquid mixing system.

[0004] The technical solution of the utility model is as follows:

[0005] On the one hand, the utility model provides a sewage gas-liquid fusion reactor, which is characterized in that it includes

[0006] An upper conical body, which is set to be hollow and has a small-end inlet and a large-end outlet;

[0007] A lower conical body, which is set to be hollow and inverted, and has a large-end inlet and a small-end outlet;

[0008] Wherein, the large-end outlet is connected and communicated with the large-end inlet so that the upper conical body and the lower conical body jointly form a spindle-shaped structure.

[0009] Further, the cone angle range of the lower conical body is 20°-60°.

[0010] Further, the cone angle range of the upper conical body is 50°-80°.

[0011] Further, both the upper conical body and the lower conical body are of conical structure.

[0012] Further, the length ratio range of the upper conical body to the lower conical body is (2-6):1.

[0013] Further, a microporous layer is provided at the connection between the large-end outlet and the large-end inlet.

[0014] Further, a bubble generator is installed at the small-end outlet.

[0015] Further, the bubble generator is set as a micro-nano bubble generating device.

[0016] According to another aspect of the present utility model, there is also provided a gas-liquid mixing system, which is characterized in that it includes the sewage gas-liquid fusion reactor as described above and a water storage part, and the water storage part is connected to the small-end inlet through a gas-liquid suction system; the water storage part is also connected to the small-end outlet through a liquid discharging system.

[0017] Further, the gas-liquid suction system includes a liquid inlet pipeline, a gas inlet pipeline and a power device; the first end of the liquid inlet pipeline is connected to the water storage part; the second end of the liquid inlet pipeline is connected to the small-end inlet; the gas inlet pipeline is connected and communicated with the liquid inlet pipeline; the power device is used to provide power for the movement of the liquid and the gas.

[0018] The beneficial effects achieved by the present utility model are as follows:

[0019] The sewage gas-liquid fusion reactor of the present utility model includes a hollow upper conical body with a small-end inlet and a large-end outlet; it also includes a lower conical body, which is set to be hollow and inverted and has a large-end inlet and a small-end outlet; wherein, the large-end outlet and the large-end inlet are connected and communicated with each other so that the upper conical body and the lower conical body together form a spindle-shaped structure; oxygen-containing gas and liquid enter through the hollow upper conical body at the same time. Since the diameter of the upper conical body increases from top to bottom, the water column will be separated by the low pressure on the bottom side of the upper conical body after entering the interior of the upper conical body to form a mist effect, so as to better mix the oxygen-containing gas into the water; and for the lower conical body communicated with the upper conical body, its diameter gradually decreases from top to bottom, which can achieve the effect of gradually increasing the pressure, facilitating the rapid outflow of the liquid therein while taking away the sewage; at the same time, the inner wall of the lower conical body itself is an inclined surface, which can also facilitate the outflow of dirt with the liquid therein to prevent the accumulation of turbid substances; the upper conical body and the lower conical body are connected to form a spindle shape, which can not only ensure effective oxygen dissolution but also prevent the accumulation of dirt.

[0030] Embodiment 1

[0031] An embodiment of the present application discloses a sewage gas-liquid fusion reactor and a gas-liquid mixing system, including a hollow upper conical body 100 having a small-end inlet 110 and a large-end outlet 120; and a lower conical body 200 which is arranged to be hollow and inverted and has a large-end inlet 210 and a small-end outlet 220; wherein the large-end outlet 120 and the large-end inlet 210 are connected and communicated with each other so that the upper conical body 100 and the lower conical body 200 together form a spindle-shaped structure.

[0032] In this embodiment, oxygen-containing gas and liquid enter through the hollow upper conical body 100 at the same time. Since the diameter of the upper conical body 100 increases from top to bottom, the water column will be separated by the low pressure on the bottom side of the upper conical body 100 to form a mist effect after entering the interior of the upper conical body 100, so as to better mix the oxygen-containing gas into the water; and the lower conical body 200 communicated with the upper conical body 100 has a diameter that gradually decreases from top to bottom, which can achieve the effect of gradually increasing pressure, facilitating the rapid outflow of the liquid therein while taking away the sewage; at the same time, the inner wall of the lower conical body 100 is an inclined surface, which can also facilitate the outflow of dirt with the liquid therein to prevent the accumulation of turbid substances; the upper conical body 100 and the lower conical body 200 are connected to form a spindle shape, which can not only ensure effective oxygen dissolution but also prevent the accumulation of dirt; preferably, the upper conical body 100 and the lower conical body 200 are integrally formed to ensure the structural stability of the embodiment of the present application.

[0033] In an alternative embodiment, the cone angle range of the lower conical body 200 is 20°-60°; so as to better discharge micron-sized particulate matters that sink rapidly; the rapidly sinking particulate matters such as mud, sand, fly ash, etc.

[0034] In an alternative embodiment, the cone angle of the upper cone 100 ranges from 50° to 80°; this angle setting facilitates the full mixing of the oxygen-containing gas and the liquid at the top of the upper cone 100.

[0035] In an alternative embodiment, both the upper cone 100 and the lower cone 200 are conical structures; this can effectively improve the strength and pressure resistance of the embodiments of the present application.

[0036] In an alternative embodiment, the length ratio of the upper cone 100 to the lower cone 200 ranges from (2 - 6):1. If this ratio range is too small, it will affect the oxygen mixing efficiency; if this ratio range is too large, it will affect the particulate discharge effect.

Large-particle dirt has been filtered out by a microfilter before entering the sewage gas-liquid fusion reactor, and the particulate dirt entering the sewage gas-liquid fusion reactor is only at the micron level.

[0038] In an alternative embodiment, a bubble generator 400 is installed at the small-end outlet 220 to further improve the gas-liquid fusion rate.

[0039] Through the above-mentioned upper cone 100, microporous layer 300, and bubble generator 400, a three-stage gas-liquid fusion structure is formed; the oxygen-containing gas and the liquid are mixed step by step and then flow out, making the fusion rate as high as 99% or more; specifically, for example, the average particle size of the bubbles generated by the upper cone 100, microporous layer 300, and bubble generator 400 gradually becomes smaller, so that the oxygen-containing gas is fused into the liquid in three steps, ensuring a high fusion rate of gas-liquid mixing.

[0040] In an alternative embodiment, the bubble generator 400 is set as a micro-nano bubble generating device; a large number of micro-nano bubbles are generated by this micro-nano bubble generating device, effectively increasing the dissolved oxygen area and being conducive to further improving the efficiency of dissolved oxygen.

[0041] In an alternative embodiment, a pressure gauge assembly 800 is provided on the upper cone 100, and the pressure gauge assembly 800 is connected to the inside of the upper cone 100 to detect the internal pressure.
