Description

Technical Field

[0001] This utility model relates to the field of aquaculture water treatment technology, specifically a carbon dioxide degassing tower that can automatically adjust alkalinity. Background Technology

[0002] Recirculating aquaculture (RAA) is currently the most advanced and promising aquaculture model. In this model, cultured organisms can grow in a stable and controllable environment, effectively preventing exogenous diseases. Because the environment is stable and controllable, it is unaffected by external seasonal temperature changes or severe weather, allowing for multiple batches of culture. Simultaneously, the cultured water can be continuously purified and reused within the system, significantly saving water resources. Furthermore, since water quality indicators and dissolved oxygen levels fully meet the rapid growth requirements of cultured organisms, another advantage of high-density aquaculture is the significant reduction in culture area. Because RIA relies primarily on specialized equipment within the system to provide a favorable culture environment, it minimizes the impact of human intervention, making it easier to promote to the general public. In RIA systems, the relationship between pH and alkalinity is crucial, requiring careful monitoring and adjustment of alkalinity and carbon dioxide levels to maintain the optimal pH for aquatic organism growth and biofilter operation. Alkalinity can be easily adjusted by adding sodium bicarbonate, which is safe, inexpensive, and easy to use. Carbon dioxide is conventionally controlled through degassing systems, such as counter-current degassing towers.

[0003] The equipment commonly available on the market consists of separate drip devices for adjusting alkalinity and separate degassing towers for removing carbon dioxide. This increases the equipment's footprint and system design costs, while also resulting in low efficiency in treating water-related indicators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a carbon dioxide degassing tower that can automatically adjust alkalinity, which has the advantage of achieving dual regulation of water alkalinity and carbon dioxide levels, thus avoiding the problem of low efficiency in treating water-related indicators.

[0005] To achieve the dual regulation of water alkalinity and carbon dioxide levels, this utility model provides the following technical solution:

[0006] A carbon dioxide degassing tower capable of automatically adjusting alkalinity includes a tower body, an inlet fixedly connected to the side wall of the tower body, an outlet fixedly connected to the top of the tower body, and a connecting box fixedly connected to the bottom of the tower body. An outlet is fixedly connected to the side wall of the connecting box. An adjusting component is installed on the inner wall of the tower body for detecting and adjusting the alkalinity of the aquaculture water. A mixing component is installed on the inner wall of the connecting box for accelerating mixing and promoting the passage of the aquaculture water through the outlet. The tower body also includes:

[0007] The regulating assembly includes a fan, which is fixedly installed on the side wall of the tower body and connected to the tower body. An automatic alkalinity regulating control cabinet and a drip box are fixedly connected to the side wall of the tower body. A drip pipe is fixedly connected to the bottom of the drip box and extends into the inner cavity of the tower body. Multiple sets of holes are opened at the bottom of the drip pipe. An automatic control valve is fixedly connected to the side wall of the drip pipe. A detection probe is fixedly connected to the bottom of the automatic alkalinity regulating control cabinet and extends into the inner wall of the connecting box. Spray plates are fixedly connected to both sides of the inner wall of the tower body. A packing layer is fixedly connected to the inner wall of the tower body and is located between the spray plates.

[0008] According to some embodiments, the hybrid component includes a servo motor, which is fixedly mounted on the side wall of the connecting box. A threaded column is fixedly connected to the output end of the servo motor, and a sliding plate is threadedly connected to the side wall of the threaded column. A control device is fixedly connected to the side wall of the outlet.

[0009] According to some embodiments, the inner wall of the tower is fixedly connected with an inclined plate, and the inclined plate is set to tilt towards the direction of the fan. The packing layer is composed of polypropylene plastic multifaceted hollow spheres.

[0010] Beneficial effects

[0011] This invention provides a carbon dioxide degassing tower that can automatically adjust alkalinity, and has the following features:

[0012] Beneficial effects:

[0013] (1) The carbon dioxide degassing tower that can automatically adjust alkalinity introduces aquaculture water into the tower body through the inlet. During the falling process, a large amount of air blown in by the blower fully exchanges gas with the dripping aquaculture water, taking away a large amount of carbon dioxide. The aquaculture water is collected at the bottom of the connecting box. The alkalinity adjustment automatic control cabinet controls the opening and closing size and time of the automatic control valve to determine the amount of sodium bicarbonate solution added to the drip box. The solution drips into the water in the connecting box through the hole at the bottom of the drip pipe, thereby realizing the function of adjusting the alkalinity of the aquaculture water and removing carbon dioxide.

[0014] (2) The carbon dioxide degassing tower that can automatically adjust alkalinity uses the threaded connection between the threaded column and the sliding plate to make the sliding plate slide back and forth in the inner cavity of the connecting box. The sliding plate stirs and mixes the aquaculture water and the sodium bicarbonate solution dripping from the drip box. When the detection value of the detection probe is within the normal range, the outlet is opened by the control device, and at the same time the sliding plate pushes the aquaculture water in the inner cavity of the connecting box to flow out of the outlet quickly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-5 A carbon dioxide degassing tower capable of automatically adjusting alkalinity includes a tower body 1, an inlet 101 fixedly connected to the side wall of the tower body 1, an outlet 102 fixedly connected to the top of the tower body 1, a connecting box 103 fixedly connected to the bottom of the tower body 1, an outlet 104 fixedly connected to the side wall of the connecting box 103, an adjusting component 2 installed on the inner wall of the tower body 1 for detecting and adjusting the alkalinity of the aquaculture water, and a mixing component 3 installed on the inner wall of the connecting box 103 for accelerating mixing and promoting the passage of the aquaculture water through the outlet 104. It also includes:

[0023] The regulating component 2 includes a fan 201, which is fixedly installed on the side wall of the tower body 1 and connected to the tower body 1. An alkalinity regulating automatic control cabinet 202 and a drip box 203 are fixedly connected to the side wall of the tower body 1. A drip pipe 204 is fixedly connected to the bottom of the drip box 203 and extends into the inner cavity of the tower body 1. Multiple sets of holes 205 are opened at the bottom of the drip pipe 204. An automatic control valve 206 is fixedly connected to the side wall of the drip pipe 204. A detection probe 207 is fixedly connected to the bottom of the alkalinity regulating automatic control cabinet 202 and extends into the inner wall of the connection box 103.

[0024] Spray plates 208 are fixedly connected to both sides of the inner wall of the tower body 1, and a packing layer 209 is fixedly connected to the inner wall of the tower body 1, with the packing layer 209 located between the spray plates 208.

[0025] It should be noted that: the aquaculture water is introduced into the inner cavity of the tower body 1 through the inlet 101. After passing through the spray plate 208, the aquaculture water enters the packing layer 209 and slowly falls under the influence of gravity. During the falling process, a large amount of air blown in by the fan 201 fully exchanges gas with the dripping aquaculture water, carrying away a large amount of carbon dioxide. The gas containing a large amount of carbon dioxide is discharged from the outlet 102 located at the top of the degassing tower. The aquaculture water finally collects at the bottom of the connecting box 103. The detection probe 207 measures the alkalinity of the aquaculture water. The measurement data is transmitted to the alkalinity adjustment automatic control cabinet 202 in the form of an electrical signal. The alkalinity adjustment automatic control cabinet 202 analyzes the transmitted alkalinity data, calculates the difference that needs to be supplemented, and then controls the opening and closing size and time of the automatic control valve 206 to determine the amount of sodium bicarbonate solution to be added to the drip box 203. The solution drips into the water in the inner cavity of the connecting box 103 through the hole 205 at the bottom of the drip pipe 204, thus realizing the function of adjusting the alkalinity of the aquaculture water.

[0026] Reference Figures 1-5 The hybrid component 3 includes a servo motor 301, which is fixedly installed on the side wall of the connecting box 103, and a threaded post 302 is fixedly connected to the output end of the servo motor 301.

[0027] The threaded column 302 has a sliding plate 303 threadedly connected to its side wall, and the outlet 104 has a control device fixedly connected to its side wall.

[0028] It should be noted that: the servo motor 301 drives the threaded column 302 to rotate. The threaded connection between the threaded column 302 and the sliding plate 303 causes the sliding plate 303 to slide back and forth in the inner cavity of the connecting box 103. The sliding plate 303 stirs and mixes the aquaculture water and the sodium bicarbonate solution dripping from the drip box 203. When the detection value of the detection probe 207 is within the normal range, the outlet 104 is opened through the control device. At the same time, the sliding plate 303 pushes the aquaculture water in the inner cavity of the connecting box 103 to flow out of the outlet 104 quickly.

[0029] Reference Figures 1-5 An inclined plate 4 is fixedly connected to the inner wall of the tower body 1, and the inclined plate 4 is set to tilt towards the direction of the fan 201;

[0030] The filler layer 209 is composed of polypropylene plastic multifaceted hollow spheres;

[0031] It should be noted that the inclined plate 4 can direct the aquaculture water flowing out of the packing layer 209 toward the blower 201, which facilitates gas exchange. The packing layer 209 is made of polypropylene plastic multi-faceted hollow spheres, which facilitates the slow descent of the aquaculture water.

[0032] Operating method: Aquaculture water is introduced into the inner cavity of tower body 1 through inlet 101. After passing through spray plate 208, the aquaculture water enters the packing layer 209 and falls slowly under gravity. During the falling process, a large amount of air is blown in by fan 201, which fully exchanges gas with the dripping aquaculture water, taking away a large amount of carbon dioxide. The gas containing a large amount of carbon dioxide is discharged from outlet 102 located at the top of degassing tower. The aquaculture water finally collects at the bottom of connecting box 103. Detection probe 207 measures the alkalinity of the aquaculture water. The measurement data is transmitted to alkalinity adjustment automatic control cabinet 202 in the form of an electrical signal. Alkalinity adjustment automatic control cabinet 202 analyzes the transmitted alkalinity data, calculates the difference that needs to be supplemented, and then controls the opening and closing size and time of automatic control valve 206 to determine the amount of sodium bicarbonate solution to be added in drip box 203. The solution drips into the water in the inner cavity of connecting box 103 through hole 205 at the bottom of drip pipe 204, realizing the function of adjusting the alkalinity of aquaculture water.

[0033] The servo motor 301 drives the threaded column 302 to rotate. The threaded connection between the threaded column 302 and the sliding plate 303 causes the sliding plate 303 to slide back and forth in the inner cavity of the connecting box 103. The sliding plate 303 stirs and mixes the aquaculture water and the sodium bicarbonate solution dripping from the drip box 203. When the detection value of the detection probe 207 is within the normal range, the outlet 104 is opened through the control device. At the same time, the sliding plate 303 pushes the aquaculture water in the inner cavity of the connecting box 103 to flow out of the outlet 104 quickly.
