Description

Technical Field

[0001] This utility model relates to the field of scrubbing tower technology, specifically to a coal chemical syngas scrubbing tower. Background Technology

[0002] Coal syngas is a synthetic gas produced from coal through processes such as gasification. Its main components are carbon monoxide and hydrogen, and it also contains small amounts of carbon dioxide, methane, nitrogen, etc. The production process involves chemically reacting coal with a gasifying agent (such as oxygen, water vapor, etc.) in specific equipment (such as a gasifier) ​​under certain temperature and pressure conditions, converting the organic matter in the coal into gas. Coal syngas has a wide range of uses. It can be used as a raw material gas for the synthesis of ammonia, methanol, and other organic synthesis industries. It can also be used as industrial and domestic fuel gas. Through processes such as Fischer-Tropsch synthesis, it can be converted into liquid fuels such as gasoline and diesel, realizing the indirect liquefaction of coal.

[0003] However, after coal chemical syngas is produced, it often contains solid impurities such as dust and particles. These solid particles move with the airflow and will cause friction and impact on the inner walls of pipelines, valves and equipment, resulting in equipment wear, shortening the service life of equipment, and increasing the cost of equipment maintenance and replacement. In addition, the temperature of coal chemical syngas is usually relatively high when it is produced, which is not conducive to subsequent process treatment and cannot guarantee that the subsequent equipment can operate under the appropriate temperature conditions, making it easy for the equipment to be damaged due to high temperature.

[0004] Therefore, this utility model proposes a coal gas scrubbing tower to solve the above problems. Utility Model Content

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1 like Figures 1-5 As shown in the figure, this embodiment proposes a coal chemical syngas scrubbing tower, including a base 1, on which a scrubbing tower body 2 is vertically and fixedly installed. An air inlet pipe 3 is fixedly installed on the outer left side of the scrubbing tower body 2, an air outlet pipe 4 is fixedly installed at the top of the scrubbing tower body 2, a drain pipe 5 is fixedly installed at the bottom of the scrubbing tower body 2, an annular pipe 6 is fixedly installed on the inner wall of the scrubbing tower body 2, and several sets of spray heads 8 are fixedly installed on the annular pipe 6. A liquid inlet pipe 7 is also fixedly installed on the outer left side of the scrubbing tower body 2, and the right side of the liquid inlet pipe 7 is sealed to the annular pipe 6.

[0020] Each spray head 8 sprays at a 45-degree angle upwards; an installation box 9 is fixedly installed on the air inlet pipe 3, and an installation groove 10 is opened at the top of the installation box 9. An installation plate 11 is slidably installed inside the installation groove 10, and a metal wire mesh filter plate 12 is fixedly installed on the installation plate 11. A handle 13 is fixedly installed at the top of the installation plate 11; a sealing gasket is fixedly installed at the connection between the installation plate 11 and the outer surface of the installation groove 10.

[0021] In this embodiment, when using this device, the operator can transport the produced coal syngas to the scrubbing tower body 2 through the inlet pipe 3. As the coal syngas passes through the inlet pipe 3, the metal mesh filter plate 12 intercepts larger solid impurities in the coal syngas. The metal mesh filter plate 12 is not only high-strength and heat-resistant, able to withstand the high temperature of the coal syngas, but it can also be reused after cleaning, thus improving the practicality of the device. Then, after the coal syngas enters the scrubbing tower body 2, the operator can connect the liquid inlet pipe 7 to a scrubbing liquid source, allowing the scrubbing liquid to... The spray head 8, which is tilted upwards at a 45-degree angle, can spray out the gas, forming an arched liquid curtain. When the dust-laden coal syngas passes through the liquid curtain formed by the washing liquid, the dust and small particulate impurities come into contact with the liquid and are captured due to inertia, gravity, diffusion, etc., and are then discharged from the drain pipe 5 with the washing liquid. This reduces the impact of dust, particulate and other solid impurities in the coal syngas on subsequent equipment, thereby improving the purity of the coal syngas and facilitating subsequent process treatment. At the same time, it can also cool the coal syngas, reducing the possibility of damage to subsequent equipment due to excessively high coal syngas temperature.

[0022] Example 2 like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that a water storage tank 14 is provided at the rear of the washing tower body 2, an inlet pipe 1401 is fixedly installed at the top of the water storage tank 14, a cavity 15 is opened inside the outer wall of the washing tower body 2, a circulating water connection pipe 16 is fixedly installed at the top of the rear end of the washing tower body 2 and is connected to the cavity 15, the other end of the circulating water connection pipe 16 extends into the interior of the water storage tank 14, a water pump 17 is fixedly installed at the bottom of the interior of the water storage tank 14, a delivery pipe 18 is fixedly installed at the bottom of the rear end of the washing tower body 2 and is connected to the cavity 15, the other end of the delivery pipe 18 is fixedly connected to the output end of the water pump 17; an installation frame 19 is fixedly installed on the outer wall of the rear end of the water storage tank 14, a bracket 20 is fixedly installed inside the installation frame 19, a cooling fan 21 is fixedly installed on the bracket 20; a protective mesh plate 22 is fixedly installed inside the installation frame 19 at the position behind the cooling fan 21; rubber pads 23 are fixedly installed at the four corners of the bottom of the base 1.

[0023] In this embodiment, when the operator uses this device to process coal syngas, the operator can start the water pump 17 to pump the water stored in the water tank 14 into the cavity 15 through the delivery pipe 18, and then return it to the water tank 14 through the circulating water connection pipe 16. This not only enhances the cooling efficiency of the coal syngas, but also cools the outer wall of the scrubbing tower body 2, making the outside temperature of the tower lower during use and easier for the operator to use, thus further enhancing the practicality of the device. In addition, the operator can also start the cooling fan 21 to cool the outer wall of the water tank 14, which can reduce the temperature of the water inside the water tank 14 to a certain extent, thereby ensuring the cooling effect on the outer wall of the scrubbing tower body 2.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
