All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.
[0021] like Figure 1 As shown, the carbonization tower gas distribution device described in the utility model includes a gas delivery pipeline 3, the bottom end of the gas delivery pipeline 3 is located at the inner bottom of the tower body 1, the gas delivery pipeline 3 includes an inclined section and a vertical section, the vertical section is located inside the tower body 1, the top of the vertical section is welded to the inclined section, the top of the inclined section passes through the tower body 1 and is connected to an external Roots blower, and the Roots blower delivers gas containing carbon dioxide to the interior of the tower body 1 through the inclined section and the vertical section of the gas delivery pipeline 3.
[0022] A feed port 4 is provided on the top side wall of the tower body 1, and the feed port 4 is connected to an external self-priming pump for conveying calcium hydroxide slurry into the tower body 1. A discharge port 8 is provided on the side wall of the bottom of the tower body 1 away from the feed port 4, and an air outlet 2 is provided on the top of the tower body 1. The inclined section of the gas delivery pipe 3 is located above the feed port 4, which can prevent the input slurry from falling on the inclined section of the gas delivery pipe 3, which helps to improve the service life of the gas delivery pipe 3; a plurality of support rods 10 are provided between the vertical section of the gas delivery pipe 3 and the tower body 1, and the support rods 10 are used to fix the gas delivery pipe 3. The axis of the vertical section of the gas delivery pipe 3 should be kept in the same straight line as the axis of the tower body 1 as much as possible, thereby helping to improve the reaction efficiency of the gas and slurry; a sampling port 6 is provided on the side wall of the bottom of the tower body 1 away from the discharge port 8, and a plurality of observation ports 9 are provided on the tower body 1. The sampling port 6 and the observation port 9 are used to observe and check the reaction of the raw materials.
[0023] Several caps 7 are fixedly mounted on the outer wall of the vertical section of the gas delivery pipeline 3. These caps 7 are inverted trumpet-shaped structures that increase the buffer area for gas entering the bottom of the tower body 1. The bottom edges of the caps 7 are provided with continuous serrations that tilt outward, which are used to segment passing bubbles and increase the contact area between the gas and the calcium hydroxide slurry. In this embodiment, there are three caps 7, and the diameter of their horizontal projection increases from bottom to top along the tower body 1, further enhancing the bubble-splitting effect. A through hole is provided on the outer wall of the top of the cap 7, with a diameter less than half the diameter of the vertical section of the gas delivery pipeline 3. This hole is used to circulate some gas and prevent gas from accumulating between the caps 7 and the gas delivery pipeline 3. In this embodiment, the diameters of the horizontal projections of the three caps are 2600 mm, 2800 mm, and 3000 mm, respectively.
[0024] Several supporting columns are fixedly arranged on the inner wall of the tower body 1, and a baffle 5 is fixedly arranged on the top of the supporting column.

The angle between the supporting column and the baffle 5 is 120° to 130°, and the angle between the supporting column and the inner wall of the tower body 1 is 60°; the baffle 5 is located above the umbrella cap 7 or between two adjacent umbrella caps 7, and is used to collide with the bubbles during their rising process, so that they are dispersed into many very small bubbles, which are evenly dispersed throughout the reactor.
[0025] The working principle of the utility model is as follows: a Roots blower delivers gas containing carbon dioxide to the bottom of a tower body 1 through a gas delivery pipe 3, and a self-priming pump delivers calcium hydroxide slurry into the interior of the tower body 1 through a feed port 4. The gas containing carbon dioxide is divided into larger bubbles by the continuous serrations on the umbrella cap 7 at the bottom of the tower body 1. During the process of rising in the tower body 1, the large bubbles come into contact with the bottom baffle 5 and are further divided into numerous smaller bubbles by the serrations on the middle and upper umbrella caps 7 and the baffle 5. The bubbles are evenly dispersed throughout the reactor, and the small bubbles react with the calcium hydroxide slurry in the tower to form calcium carbonate slurry. Due to the strong stirring effect of the fluid inside the tower body 1, the rising speed of the bubbles is significantly slowed, which is conducive to increasing the reaction rate and shortening the reaction time.
