Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide processing equipment, in particular to a carbon dioxide capture and purification device. Background Art

[0002] Carbon dioxide is one of the main causes of global warming and extreme climate disasters. In recent years, carbon dioxide capture and purification has become a hot research topic. Using captured and purified carbon dioxide for oil recovery and sealing it in abandoned oil layers has important economic and social benefits.

[0003] In some factories nowadays, one end of the air suction pipe is usually set above the carbon dioxide exhaust device, and the exhaust carbon dioxide is sent into the purification tower by the suction of the air suction pipe, and then ethanolamine is sprayed in the purification tower to absorb the carbon dioxide gas. However, some existing purification towers have no restrictions inside, and the air entering the purification tower can go straight up and down, and carbon dioxide is heavier than air. When purifying carbon dioxide, it is necessary to use fans and other items to push the carbon dioxide to move, but when such items blow carbon dioxide, the movement speed of carbon dioxide is faster, so the purification tower needs to be built higher to better absorb carbon dioxide, and building the purification tower higher consumes more materials. In order to solve this technical problem, the utility model proposes a carbon dioxide capture and purification device. Utility Model Content

[0004] The utility model aims to provide a carbon dioxide capture and purification device, which has the characteristic of not requiring a purification tower to be built too high.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a carbon dioxide capture and purification device, comprising a purification tower, wherein a mounting plate is connected to the interior of the purification tower, a suction pipe is connected to the interior of the mounting plate, an upflow plate is connected to the upper surface of the mounting plate, a water storage tank is provided inside the purification tower, a fan is installed inside the purification tower, a support column is connected to the interior of the purification tower, a spiral sheet is connected to the outer surface of the support column, an extension rod is connected to the outer surface of the support column, a nozzle is installed inside the extension rod, an infusion port is provided inside the extension rod, an infusion tube is connected to the interior of the purification tower, a filter plate 1 is slidably connected to the interior of the purification tower, and a limiting mechanism is provided inside the purification tower.

[0006] In order to control the position to which the limit block can move, as a preferred carbon dioxide capture and purification device of the utility model, the limit mechanism includes a limit block, the outer surface of the limit block is connected to the outer surface of the filter plate, and the outer surface of the limit block is slidably connected to the inside of the purification tower.

[0007] In order to prevent the filter plate from moving, as a preferred embodiment of the carbon dioxide capture and purification device of the present invention, the interior of the limit block is slidably connected with an insertion rod, and the outer surface of the insertion rod is slidably connected to the interior of the purification tower.

[0008] In order to allow the rod to be inserted into the purification tower when the limit block moves to a suitable position, as a preferred carbon dioxide capture and purification device of the present invention, one end of the rod is connected to a spring, and the end of the spring away from the rod is connected to the outer surface of the filter plate.

[0009] In order to allow the gas to escape from the purification tower, as a preferred carbon dioxide capture and purification device of the utility model, an air outlet is opened inside the purification tower, and the inner side wall of the air outlet is connected to a filter plate 2.

[0010] In order to fix the position of the support column, as a preferred carbon dioxide capture and purification device of the present invention, the outer surface of the suction pipe is connected to the inside of the purification tower, and the upper surface of the upflow plate is connected to the bottom surface of the support column.

[0011] In order to deliver ethanolamine into the support column, as a preferred carbon dioxide capture and purification device of the present invention, the outer surface of the spiral sheet is connected to the interior of the purification tower, and one end of the infusion tube is connected to the interior of the support column.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model cooperates with the spiral blades and the extension rods and other components. First, the spiral blades are connected to the support column and the purification tower, so that the spiral blades divide the space in the purification tower, so that the gas entering the purification tower can only move upward along the spiral blades, and the spiral blades are used to increase the distance that the gas needs to travel to reach the top. The extension rod can be extended from the support column, and the extension of the extension rod increases the range of the spray head, so that the liquid sprayed by the spray head can better combine with the passing carbon dioxide, increasing the absorption efficiency of ethanolamine for carbon dioxide, so that the shorter purification tower can also absorb carbon dioxide well, which is very convenient and solves the problem of needing to build a higher purification tower.

[0014] 2. The utility model cooperates with the fan, the suction pipe and other components. The fan can drive the flow of air in the purification tower. The air is blown by starting the fan to push the carbon dioxide upward. The suction pipe can transport the carbon dioxide into the purification tower and send the carbon dioxide to the upper part of the fan through the suction pipe, thereby preventing the carbon dioxide from being blown into the water tank. The utility model is very easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
