Description

Technical Field

[0001] In aquatic organism breeding systems, degassing devices can control the content of harmful gases in water, such as but not limited to carbon dioxide and hydrogen sulfide.

[0002] Prior art generally sprinkles water droplets or water mist downward and uses a blower to blow air upward to achieve gas-liquid convection and accelerate the removal of harmful gases in the water. This is very efficient, but the power consumption is large, the cost is high, and the blower requires maintenance, so there is room for improvement. In addition, the water droplets are easily blown outside the device, so there is room for improvement. Summary of the Invention

[0003] In order to solve the above problems, the present invention proposes a design method of a degassing device, a degassing device, and aquatic organism breeding equipment.

[0004] The design method of the degassing device is based on the improvement of the traditional design. The traditional design includes a convection container (1), a water inlet channel (2), an air inlet channel (3) and a downpipe (5). The water inlet channel (2) is connected to the upper section of the convection container (1), the air inlet channel (3) is connected to the lower section of the convection container (1), and the downpipe (5) discharges the water in the convection container (1) downward. The excellent design is: An air suction pipe (4) is designed, wherein the upper end of the air suction pipe (4) is communicated with the upper section of the convection container (1), and the lower end is communicated with the downpipe (5); The height and diameter of the downpipe (5) are designed so that the negative pressure generated when water flows down the downpipe (5) can draw air from the air intake pipe (4) and discharge the gas downward.

[0005] The degassing device comprises a convection container (1), a water inlet channel (2), an air inlet channel (3) and a downpipe (5), wherein the water inlet channel (2) is communicated with the upper section of the convection container (1), the air inlet channel (3) is communicated with the lower section of the convection container (1), and the downpipe (5) discharges water in the convection container (1) downward. The excellent design is as follows: It includes an air intake pipe (4), the upper end of the air intake pipe (4) is connected to the upper section of the convection container (1), and the lower end is connected to the downpipe (5); When water flows downward through the downpipe (5), negative pressure is formed in the pipe, thereby bringing the gas in the convection container (1) down through the suction pipe (4) and discharging it along with the water.

[0006] Furthermore, the gas-liquid contact area in the convection container (1) is larger than the gas-liquid contact area in the downpipe (5).

[0007] Furthermore, the height of the downpipe (5) is smaller than the height of the convection container (1), ensuring that the gas-liquid convection time in the convection container (1) is greater than the gas-liquid mixing time in the downpipe (5).

[0008] Furthermore, the downpipe (5) is smaller than the water inlet channel (2), so that water can fill the downpipe (5) and generate negative pressure.

[0009] Furthermore, a drip plate (8) is provided in the convection container (1) for generating water droplets to increase the gas-liquid contact area.

[0010] Furthermore, the convection container (1) is provided with a filler (10), which can enhance the gas-liquid contact and cultivate beneficial bacteria.

[0011] Furthermore, the downpipe (5) is provided with a diamond-shaped gas-liquid mixer (11) to enhance gas-liquid mixing, facilitate the continuation of negative pressure, and maintain stable air intake.

[0012] Furthermore, the sewer pipe (5) has a Venturi structure, and the air inlet of the Venturi structure is connected to the suction pipe (4) to maintain stable suction.

[0013] Furthermore, it also includes an air flotation separation tube (6), the lower end of which is connected to the sewer pipe (5) to collect bubbles and discharge some organic matter.

[0014] Furthermore, the flotation separation tube (6) is provided with a first regulating valve (9) for regulating the internal pressure of the flotation separation tube (6), thereby regulating the sewage discharge concentration and speed; see the inventor's patent CN202421047282.6 flotation foam collection structure, mineral powder flotation device, breeding device, and water purification device.

[0015] Furthermore, the upper section of the air intake pipe (4) is located inside the convection container (1), and the lower section is located inside the downpipe (5).

[0016] Furthermore, the upper portion of the air intake pipe (4) is a curved pipe with its opening facing downward.

[0017] Furthermore, the upper end of the air intake pipe (4) is provided with a waterproof cover (7) to prevent direct impact of the water flow from the water inlet channel (2).

[0018] Furthermore, the air inlet passage (3) has a one-way valve.

[0019] Furthermore, the water inlet channel (2) is provided with an atomizing device to atomize the inlet water.

[0020] Furthermore, the upper end of the air intake pipe (4) is higher than the upper end of the water inlet channel (2).

[0021] Furthermore, the upper end of the convection container (1) is conical.

[0022] Furthermore, the air inlet passage (3) is provided with a second regulating valve (12) for regulating the air inlet speed, thereby controlling the air pressure in the convection container (1).

[0023] The aquatic organism breeding equipment is provided with a degassing device, and the excellent design thereof lies in that the degassing device is the aforementioned degassing device.

[0024] Principle: The gas in the convection container (1) is sucked away by the downstream water, generating negative pressure, accelerating the degassing of the water body, and the gas in the convection container (1) is taken away by the downstream water. The negative pressure suction in the downpipe (5) will cause a small amount of harmful gas to dissolve back into the water. However, as long as the gas-liquid contact area in the convection container (1) is larger than the gas-liquid contact area in the downpipe (5), it can be ensured that the removal speed is greater than the dissolution speed, and the harmful gas in the water can be effectively removed. The convection container (1) is air-enclosed water, while the downpipe (5) is water-enclosed air. Compared with the realization of micron bubbles, the energy required to realize micron droplets is lower. Therefore, the number of micron droplets in the convection container (1) is greater than the number of micron bubbles in the downpipe (5). Therefore, it is easy to realize that the gas-liquid contact area in the convection container (1) is greater than the gas-liquid contact area in the downpipe (5). Therefore, the present invention can effectively degas. Since the gas and liquid in the downpipe (5) flow in the same direction and the gas and liquid in the convection container (1) flow in the opposite direction, the gas exchange rate in the convection container (1) is significantly greater than the gas exchange rate in the downpipe (5), and thus the present invention can effectively degas. Beneficial effects

[0025] The structure is simple and easy to manufacture, the cost is low, it is easy to use, not easy to damage and very durable. Because it is a fixed tube cavity, maintenance is very little; no fan is required, which saves energy.

[0026] Since the gas is finally mixed with the discharged water, there is no need to worry about droplets being blown away, making it easier to use.

[0027] creativity: China Patent Examination Guidelines, Part II, Chapter 4, 3.2.2 Judgment of Significant Progress: When evaluating whether an invention has significant progress, the main consideration should be whether the invention has beneficial technical effects. In the following cases, the invention should generally be considered to have beneficial technical effects and significant progress: (4) Although the invention has negative effects in some aspects, it has obvious positive technical effects in other aspects. Even though the degassing efficiency of the present invention is not the highest, it has significant progress in manufacturing difficulty, cost, durability, maintenance, and energy saving. Therefore, the present invention meets the requirements of the China Patent Examination Guidelines for creativity and has creativity. BRIEF DESCRIPTION OF THE DRAWINGS
