Description

Technical Field

[0001] The utility model relates to the technical field of distillation towers, in particular to a horizontal cooling reflux tower head. Background Art

[0002] The horizontal cooling reflux tower head is a common chemical equipment, which is mainly used to separate and purify components in gas mixtures. The equipment usually consists of a tower bed at the bottom of the tower and a tower head at the top of the tower. During operation, the gas mixture enters the tower bed from the bottom of the tower and contacts with the liquid through the packing layer or plate layer. During the contact process, some components in the gas will be adsorbed or dissolved into the liquid, thereby achieving the purpose of separation and purification. As the operation proceeds, the liquid will gradually flow downward, while the gas will rise from the tower bed. When the gas reaches the top of the tower, it will pass through the cooling part of the tower head. During the cooling process, the vapor in the gas will condense into liquid and flow down along the inner wall of the tower head shell, and finally contact with the liquid in the tower bed for further separation.

[0003] In this way, the horizontal cooling reflux tower head can effectively separate and purify the components in the gas mixture, improve the product purity and recovery rate, and it is widely used in petrochemical, oil refining, fertilizer, natural gas processing and other fields in chemical production.

[0004] The internal reflux tower head for a distillation tower disclosed on the Chinese patent website (publication number CN210698868 U) is an internal reflux tower head for a distillation tower. By rotating the adjustment dial, the opening and closing of the liquid phase extraction pipe and the reflux pipe can be controlled, and the liquid phase extraction pipe and the reflux pipe can be freely switched between the states of being opened at the same time and one of them being opened, so that the amount ratio between the internal reflux liquid and the extraction liquid can be accurately controlled, and the accuracy of distillation is improved. In addition, the utility model is a purely mechanical structure, which is much cheaper than equipment such as solenoid valves, and effectively reduces production costs.

[0005] The existing internal reflux head for distillation tower can only control the switching between the liquid phase extraction pipe and the reflux pipe between the states of opening at the same time and opening one of them by rotating the adjustment dial. It is impossible to freely control the opening and closing states of the liquid phase extraction pipe and the reflux pipe, which increases the operation time and causes inconvenience. In addition, gaps are easily generated between the extraction pipe and the reflux pipe when adjusting the flow rate, resulting in leakage, which reduces the accuracy of distillation and is more expensive.

[0027] The protruding end surface of the meniscus 10 contacts the outer surface of the rubber airbag 9, and an L-shaped cavity 11 is opened inside the partition plate 6. The setting of the meniscus 10 can more conveniently adjust the size of the flow in the device. The addition of the rubber airbag 9 allows the gap of the square hole 7 inside the partition plate 6 to fit together to prevent the outflow of substances. The inner wall of the L-shaped cavity 11 is provided with a first bevel gear 12 and a second bevel gear 13, and the first bevel gear 12 and the second bevel gear 13 are meshed for transmission.
