Description

Technical Field

[0001] The utility model relates to the technical field of carbonating towers, and particularly relates to a calcium carbonate carbonating tower. Background Art

[0002] Calcium carbonate is one of the important inorganic powder fillers, and is widely used in industries such as plastics, rubber, paper making, medicine, food, etc. The main production processes include calcination, aging, cooling, carbonation, thickening, drying, etc. Among them, the carbonation process is to mix carbon dioxide with compressed air and send it into the carbonating tower through the air inlet pipe to neutralize with calcium hydroxide to produce calcium carbonate. The bubble size and uniformity of carbon dioxide directly affect the particle size of calcium carbonate. At present, during the carbonation process, after carbon dioxide is mixed with compressed air, it is directly sent into the carbonating tower through the air inlet pipe. The carbon dioxide bubbles are large and unevenly distributed, resulting in uneven carbonation, and further causing a large difference in the particle size of calcium carbonate particles, affecting the product quality. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a calcium carbonate carbonating tower to solve the above deficiencies in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A calcium carbonate carbonating tower, comprising: a tower body, an air inlet pipe is arranged inside the tower body, a guiding component is fixedly sleeved outside the air inlet pipe, the guiding component includes a connecting pipe, the upper and lower ends of the connecting pipe are respectively fixedly connected with a second conical filter screen and a third conical filter screen, a stirring element is placed inside the tower body, and a first conical filter screen is arranged between the stirring element and the third conical filter screen. When the pressurized carbon dioxide is transported into the guiding component through the air inlet pipe, the pressurized carbon dioxide impacts on the third conical filter screen, so that part of the carbon dioxide passes through the third conical filter screen and impacts on the calcium hydroxide solution that passes through the first conical filter screen under the agitation of the stirring element.

[0005] Further, the connection position between the connecting pipe and the third conical filter screen is rounded.

[0006] Further, one end of the air inlet pipe is located at the middle position of the connecting pipe, and the other end of the air inlet pipe is communicated with a carbon dioxide gas source.

[0007] Further, the small ends of the second conical filter screen and the third conical filter screen are both arranged upward, and the second conical filter screen is fixedly connected to the air inlet pipe.

[0008] Further, a liquid inlet pipe is arranged at the top of the tower body.

[0009] Further, the first conical filter screen is fixedly installed on the inner wall of the tower body.

[0010] Furthermore, the axes of the tower body, the intake pipe, the second conical filter screen, the third conical filter screen, and the connecting pipe coincide.

[0011] In the above technical solution, the beneficial effects of a calcium carbonate carbonization tower provided by the present utility model are as follows:

[0012] By providing a guiding component, the present utility model enables the pressurized carbon dioxide discharged from the intake pipe to impact on the third conical filter screen, allowing some carbon dioxide to pass through the third conical filter screen and come into full contact with the calcium hydroxide solution stirred by the agitator below the third conical filter screen. Another part of the carbon dioxide moves along the outer side surface of the third conical filter screen until it impacts on the inner side wall of the connecting pipe and then moves upward. After being intercepted by the second conical filter screen, the carbon dioxide bubbles are broken, which is conducive to the contact between carbon dioxide and calcium hydroxide, enabling carbon dioxide to be quickly distributed to various positions within the tower body. Subsequently, through the agitation of the calcium hydroxide solution by the agitator and the impact between the pressurized carbon dioxide bubbles and each layer of sieve mesh, etc., the mixing rate of carbon dioxide and calcium hydroxide is further enhanced, improving the quality and production efficiency of calcium carbonate.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0022] Please refer to FIGS. 1-3. A calcium carbonate carbonization tower includes: a tower body 1. An air inlet pipe 3 is arranged inside the tower body 1. A guiding component is fixedly sleeved outside the air inlet pipe 3. The guiding component includes a connecting pipe 9. The upper and lower ends of the connecting pipe 9 are respectively fixedly connected to a second conical filter screen 7 and a third conical filter screen 8. A stirring element 5 is placed inside the tower body 1. The tower body 1 is installed on a stirring main machine 2, and the stirring main machine 2 drives the stirring element 5 to rotate. A first conical filter screen 6 is arranged between the stirring element 5 and the third conical filter screen 8. After the pressurized carbon dioxide is transported into the guiding component through the air inlet pipe 3, the pressurized carbon dioxide impacts on the third conical filter screen 8, causing part of the carbon dioxide to pass through the third conical filter screen 8 and collide with the calcium hydroxide solution that passes through the first conical filter screen 6 under the agitation of the stirring element 5.

[0023] Specifically, by setting the guiding component in the present invention, the pressurized carbon dioxide discharged from the air inlet pipe 3 impacts on the third conical filter screen 8, causing part of the carbon dioxide to pass through the third conical filter screen 8 and come into full contact with the calcium hydroxide solution agitated by the stirring element 5 below the third conical filter screen 8. Another part of the carbon dioxide moves along the outer side surface of the third conical filter screen 8 until it impacts on the inner side wall of the connecting pipe 9 and then moves upward. After being intercepted by the second conical filter screen 7, the carbon dioxide bubbles are broken, which is conducive to the contact between carbon dioxide and calcium hydroxide, enabling carbon dioxide to be quickly distributed to various positions inside the tower body 1. Then, through the agitation of the calcium hydroxide solution by the stirring element 5, the impact between the pressurized carbon dioxide bubbles and each layer of sieve mesh, etc., the mixing rate of carbon dioxide and calcium hydroxide is further enhanced, improving the quality and production efficiency of calcium carbonate.

[0024] Furthermore, the connection position between the connecting pipe 9 and the third conical filter screen 8 is rounded.

[0025] Specifically, by rounding the corners between the third conical filter screen 8 and the connecting pipe 9, the corners of the connection between the third conical filter screen 8 and the connecting pipe 9 are replaced by smooth curved surfaces, so that the pressurized carbon dioxide that does not pass through the third conical filter screen 8 gradually forms bubbles and impacts the second conical filter screen 7 along the curved surface. The carbon dioxide bubbles will burst at the position of the second conical filter screen 7, thereby promoting the fusion of carbon dioxide and calcium hydroxide and improving the mixing efficiency.

[0026] Further, one end of the air inlet pipe 3 is located at the middle position of the connecting pipe 9, and the other end of the air inlet pipe 3 is communicated with a carbon dioxide gas source.

[0027] Specifically, setting the outlet end of the air inlet pipe 3 at the middle position of the connecting pipe 9 is to enable the pressurized carbon dioxide to have enough time to form more carbon dioxide bubbles, and to ensure that the pressurized carbon dioxide discharged from the air inlet pipe 3 can impact on the outer surface of the entire third conical filter screen 8, so that more carbon dioxide bubbles are intercepted and burst by the third conical filter screen 8, thereby accelerating the mixing efficiency. At the same time, due to the excessive density of carbon dioxide, the carbon dioxide that has not had time to form bubbles passes through the third conical filter screen 8 and gradually forms carbon dioxide bubbles, and then contacts the stirred calcium hydroxide solution below, promoting the mixing efficiency.

[0028] Further, the small ends of both the second conical filter screen 7 and the third conical filter screen 8 are arranged upward, and the second conical filter screen 7 is fixedly connected to the air inlet pipe 3.

[0029] Specifically, arranging the small ends of both the second conical filter screen 7 and the third conical filter screen 8 upward is to enable the carbon dioxide to disperse evenly, ensure the uniform production of calcium carbonate, and make the formed particle sizes uniform.

[0030] Further, a liquid inlet pipe 4 is provided at the top of the tower body 1.

[0031] Specifically, the liquid inlet pipe 4 is used to inject calcium hydroxide solution into the tower body 1, and a drain pipe 10 is provided at the bottom of the tower body 1 for discharging the product after the reaction between carbon dioxide and calcium hydroxide.

[0032] Further, the first conical filter screen 6 is fixedly installed on the inner wall of the tower body 1 and is installed by means of screw connection, which is convenient for replacing the damaged first conical filter screen 6.

[0033] Further, the axes of the tower body 1, the air inlet pipe 3, the second conical filter screen 7, the third conical filter screen 8, and the connecting pipe 9 coincide, so that the carbon dioxide discharged from the air inlet pipe 3 diffuses from the central position of the tower body 1 to the surroundings, ensuring that the carbon dioxide distribution in the tower body 1 is as uniform as possible.

[0034] In the present utility model, refer to Figures 1 to 3, first, the pressurized carbon dioxide discharged from the intake pipe 3 impacts on the third conical filter screen 8, causing part of the carbon dioxide to pass through the third conical filter screen 8. Under the agitation of the stirring main body 2 driving the stirrer 5, the calcium hydroxide solution impacts on the first conical filter screen 6, and the solution passes through the first conical filter screen 6 to form some bubbles, which then impact on that part of the carbon dioxide passing through the third conical filter screen 8. With the rupture of the bubbles, the mixing of carbon dioxide and calcium hydroxide is further accelerated. Another part of the carbon dioxide gradually forms bubbles and impacts on the second conical filter screen 7 along the curved surface formed by the connection between the third conical filter screen 8 and the connecting pipe 9. The carbon dioxide bubbles will rupture at the position of the second conical filter screen 7, thereby promoting the fusion of carbon dioxide and calcium hydroxide.

[0035] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
