Description

Technical Field

[0001] The invention relates to the technical field of preparing acetylene by cracking natural gas, in particular to a high-efficiency degassing tower for preparing acetylene by cracking natural gas. Background Art

[0002] Natural gas cracking to produce acetylene is an important method for industrial production of acetylene. The basic principle is to use high temperature to crack low-carbon alkanes (mainly methane) in natural gas into low-carbon unsaturated hydrocarbons and hydrogen, and even further decompose them into elemental carbon and hydrogen. In the process of natural gas cracking to produce acetylene, it is necessary to remove carbon dioxide from the air, and then a degassing tower is needed.

[0003] However, the degassing towers currently available on the market for the preparation of acetylene by cracking natural gas are not very efficient. They can only allow the gas to flow naturally in the degassing tower for separation and degassing, thereby reducing the degassing speed of the degassing tower, increasing the time required for the degassing work of the degassing tower, reducing the working efficiency of the degassing tower, and being not conducive to the long-term use of the degassing tower. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a high-efficiency degassing tower for preparing acetylene by cracking natural gas, which has the function of high-efficiency degassing and solves the problems in the above-mentioned background technology.

[0005] (II) Technical solution To achieve the above object, the present invention provides the following technical solution: a high-efficiency degassing tower for preparing acetylene by cracking natural gas, comprising a degassing mechanism, the outer wall of which is fixedly connected to a climbing mechanism, and the bottom of which is fixedly connected to a liquid outlet mechanism.

[0006] The degassing mechanism comprises: The top of the degassing tower body is fixedly connected with the tower top, and the top of the tower top is fixedly connected with the exhaust pipe, one end of the exhaust pipe is fixedly connected with the top exhaust device, and one side of the bottom exhaust device is fixedly connected with the exhaust pipe, the outer wall of the exhaust pipe is movably connected with the lower rotating threaded lock buckle, the bottom of the bottom exhaust device is fixedly connected with the lower plate, and one side of the lower plate is fixedly connected with the supporting column. The outer wall of the degassing tower body is fixedly connected with the liquid inlet threaded pipe, and the outer wall of the liquid inlet threaded pipe is movably connected with the upper rotating threaded lock buckle, the top of the degassing tower body is fixedly connected with the tower top, the top of the tower top is fixedly connected with the exhaust pipe, one end of the exhaust pipe is fixedly connected with the top exhaust device, and one side of the top exhaust device is fixedly connected with the exhaust pipe, which can make the degassing tower for preparing acetylene from natural gas cracking more convenient to use and can effectively separate and degas the internal gas, thereby improving the degassing efficiency of the degassing tower, reducing the time required for degassing the degassing tower, improving the overall work efficiency of the staff, and being conducive to the long-term use of the degassing tower.

[0007] Furthermore, the outer wall of the degassing tower body is fixedly connected with connecting columns, and the number of connecting columns is not less than three. The design of a large number of connecting columns can provide multiple support points for the degassing tower body, so that the pressure brought by the degassing mechanism is shared by multiple connecting columns, thereby improving the overall stability of the degassing tower.

[0008] Furthermore, a ladder is fixedly connected to one end of the connecting column, and the height of the ladder is higher than the height of the degassing tower body, which facilitates the staff to reach the top of the degassing tower.

[0009] Furthermore, a drain pipe is fixedly connected to the bottom of the degassing tower body, and the drain pipe is curved. The curved drain pipe can avoid the drain outlet being located directly above the lower plate, thereby avoiding the influence of the lower plate on the collection of discharged liquid and improving the convenience of subsequent collection of the discharged liquid.

[0010] Furthermore, one end of the drain pipe is fixedly connected to a pipe cover, and the diameter of one end of the pipe cover is larger than the diameter of the drain pipe, so as to facilitate sealing the bottom liquid outlet of the degassing tower body.

[0011] Furthermore, one end of the air inlet pipe is fixedly connected to the bottom of the degassing tower body, and the air inlet pipe is located at the bottom center of the degassing tower body, so as to facilitate the degassed gas to enter the interior of the degassing tower body.

[0012] Furthermore, one end of the support column is fixedly connected to the outer wall of the degassing tower body, and the number of support columns is not less than three. The design of multiple support columns can provide multiple support points for the degassing tower as a whole, thereby reducing the pressure on each support column and providing more stable support for the degassing tower body.

[0013] Furthermore, the bottom of the bottom air suction device is fixedly connected to the top of the lower plate, and the bottom air suction device is located at the top center of the lower plate, providing support for the bottom air suction device.

[0014] The present invention provides a high-efficiency degassing tower for preparing acetylene by cracking natural gas. It has the following beneficial effects: 1. The high-efficiency degassing tower for preparing acetylene by cracking natural gas has a degassing mechanism, and the liquid inlet threaded pipe is fixed to the external filtrate input pipe by the upper rotating threaded lock, and the air suction threaded pipe is fixed to the outer wall gas input pipe by the lower rotating threaded lock, and then connected to the outlet pipe through the external gas collection device. At this time, the filtrate enters the degassing tower body through the liquid inlet threaded pipe, and the bottom exhaust device sends other gases that need to be degassed into the degassing tower body through the air inlet pipe. At this time, the bottom filtrate degases the preparation gas entering the bottom, and the degassed gas is extracted out of the degassing tower body through the top exhaust device, and then sent to other working equipment through the outlet pipe. The degassing tower for preparing acetylene by cracking natural gas can be used more quickly and conveniently, and the internal gas can be separated and degassed efficiently, thereby improving the degassing efficiency of the degassing tower, reducing the time required for degassing the degassing tower, improving the overall work efficiency of the staff, and facilitating the long-term use of the degassing tower.

[0015] 2. The high-efficiency degassing tower for preparing acetylene by cracking natural gas has a climbing mechanism, so that the staff can climb to the top of the degassing tower body by climbing the ladder, and then connect the external pipeline with the outlet pipe to complete the overall connection of the degassing tower. It is convenient for the staff to connect the degassing tower with external equipment, and improves the convenience of the staff to connect the degassing tower externally.

[0016] 3. The high-efficiency degassing tower for preparing acetylene by cracking natural gas has a liquid outlet mechanism. When the degassing tower is not in use, the pipe cover is opened and the filtrate inside the degassing tower body is discharged through the liquid discharge pipe, so that the inside of the degassing tower body is emptied. It is convenient to empty the inside of the degassing tower and to store it when the degassing tower is not in use. BRIEF DESCRIPTION OF THE DRAWINGS
