Abstract
Description
Technical Field
[0001] The utility model relates to the field of gas-liquid mixing, in particular to a coal-based ethylene glycol gas-liquid mixing device. Background Art
[0002] In the production of coal-to-ethylene glycol, it is usually necessary to evenly distribute oxalate in hydrogen so that the reaction proceeds smoothly. For example, Chinese patent CN203316022U discloses a simple device for coal-to-ethylene glycol pipeline gas-liquid mixing, including a hydrogen main pipeline, an oxalate liquid inlet pipe introduced from the wall of the hydrogen main pipeline, the oxalate liquid inlet pipe is provided with a straight pipe section extending along the axial direction of the hydrogen main pipeline, a head is provided at the end of the straight pipe section, and a small hole communicating with the inner cavity of the hydrogen main pipeline is opened on the side wall, a mixing chamber is formed between the outer wall of the straight pipe section and the inner wall of the hydrogen main pipeline, the end of the straight pipe section faces the gas inlet of the hydrogen main pipeline, so that the hydrogen in the hydrogen main pipeline and the oxalate in the straight pipe section flow in the opposite direction, and the oxalate is sprayed into the mixing chamber through the small hole on the side wall, vaporized and mixed with the hydrogen. The above patent allows oxalate to be rapidly vaporized in the main gas pipeline and evenly mixed with hydrogen. The mixing speed is fast and the mixing effect is good, which can ensure the smooth progress of production. When oxalate is sprayed into the mixing chamber through the small holes on the side wall for vaporization and mixing, it only relies on the flow of gas for mixing and cannot be stirred. Therefore, effective mixing cannot be achieved. For this reason, we have proposed a coal-to-ethylene glycol gas-liquid mixing device. Utility Model Content

[0021] See also Figure 1-4 A coal-to-ethylene glycol gas-liquid mixing device comprises a hydrogen main pipeline 1, an oxalate liquid inlet pipe is arranged on the hydrogen main pipeline 1, one end of the oxalate liquid inlet pipe is located outside the hydrogen main pipeline 1, and the end of the oxalate liquid inlet pipe extending into the hydrogen main pipeline 1 is connected to the inner wall of the hydrogen main pipeline 1, a plurality of groups of outlet holes 5 are evenly arranged at one end of the oxalate liquid inlet pipe extending into the hydrogen main pipeline 1, a rotating stirring structure is arranged at one end of the oxalate liquid inlet pipe extending into the hydrogen main pipeline 1, and the oxalate liquid has a certain flow rate in the oxalate liquid inlet pipe, so that the oxalate passes through the oxalate liquid inlet pipe. The oxalate inlet pipe is located at the outlet hole 5 on the upper side wall at one end of the hydrogen main pipeline 1 and is quickly vaporized. The vaporized oxalate is evenly mixed with the hydrogen in the hydrogen main pipeline 1, and during the flow of hydrogen in the hydrogen main pipeline 1, its impact force will drive the rotating stirring structure to rotate, so that the newly vaporized oxalate is broken up, so that the hydrogen is fully mixed. The transportation of hydrogen in the hydrogen main pipeline 1 and the transportation of oxalate in the oxalate inlet pipe can be carried out continuously, and the mixing of hydrogen and oxalate can also be carried out continuously, which is convenient for realizing continuous production.
[0022] Furthermore, an observation tube 2 is provided on the outside of the hydrogen main pipeline 1, and an openable cover is provided at the end of the observation tube 2. An observation window is fixedly installed on the cover, through which the mixing conditions inside the hydrogen main pipeline 1 can be effectively observed, and maintenance can be carried out by opening the cover and looking through the observation tube 2.
[0023] Furthermore, the oxalate liquid inlet pipe includes an external pipe 3 and an internal pipe 4, the external pipe 3 and the internal pipe 4 are fixedly connected together, the external pipe 3 is located on the outside of the hydrogen main pipe 1, the internal pipe 4 is located on the inside of the hydrogen main pipe 1, a rotating stirring structure is arranged on the internal pipe 4, and a plurality of groups of outlet holes 5 are respectively opened on both sides of the internal pipe 4 corresponding to the rotating stirring structure.
[0024] Furthermore, the rotary stirring structure includes a rotary connector, a connecting rod 10 and a stirring blade 11. The rotary connector is arranged on the outside of the internal tube 4, and multiple groups of connecting rods 10 are equidistantly arranged on the outside of the rotary connector. The stirring blade 11 is fixedly installed on one end of the connecting rod 10 away from the rotary connector.
