Description
Technical Field
[0001] The utility model relates to the technical field of methanol production, in particular to a methanol washing tower used for methanol production. Background Art
[0002] Methanol is an organic compound with the chemical formula CH3OH, also known as hydroxymethane, wood alcohol or wood spirit. It is a colorless, transparent, flammable liquid with a similar odor to ethanol. The molecular weight of methanol is 32.04 and the boiling point is 64.7℃. Methanol is widely used in industry, including as a solvent, antifreeze, fuel or denaturant. In addition, methanol is also an important industrial raw material, mainly used to remove toxic components such as hydrogen sulfide and carbon disulfide in combustible gases. The methanol washing tower can effectively remove sulfur in natural gas. Toxic components such as hydrogen and carbon disulfide are removed, and the pollution of these harmful gases to the environment is reduced to protect the atmospheric environment and the ecosystem. The methanol washing tower adopts a bubble tray and a fixed valve tray arranged up and down. Natural gas can quickly remove harmful substances by mixing with methanol liquid. When the existing washing tower is working, toxic components such as hydrogen sulfide and carbon disulfide contained in natural gas enter the washing tower through the air inlet and are fully contacted with the methanol solution in the bubble tray. Hydrogen sulfide and carbon disulfide will react chemically under the action of methanol. The gas-liquid contact is sufficient, and harmful substances are removed. The components are effectively absorbed into the methanol solution. At this time, the methanol solution is a mixed liquid containing natural gas and harmful substances. Then most of the pure natural gas is discharged through the exhaust port, and a small part of the natural gas is still in the mixed liquid until the mixed liquid flows out of the bubble cap tray and falls downward to the surface of the solid valve tray. Through the height difference between the upper and lower trays and the throttling of the throttling hole on the solid valve tray, all the natural gas in the mixed liquid is released and discharged through the exhaust port. The remaining liquid passes through the throttling hole and falls into the bottom of the tower for discharge. There are some problems. When the traditional methanol washing tower is working, in order to ensure that the solution inside the bubble cap tray can flow out, there will be a liquid level difference on the upper surface of the bubble cap tray. The lower the liquid level, the smaller the resistance of natural gas through the bubble cap, and the easier it is for natural gas to pass through the area with low liquid level, resulting in uneven gas-liquid contact and affecting the absorption efficiency. After a long period of work, the reacted methanol solution will carry harmful substances and fall onto the surface of the solid valve tray. If this continues for a long time, the throttling hole on the solid valve tray will be attached by harmful substances and cause blockage. For this reason, we propose a washing tower for methanol production. Utility Model Content

[0025] The working principle of the alcohol washing tower for methanol production provided by the utility model is as follows: when the alcohol washing tower is working, natural gas is delivered into the air inlet chamber 6 through the air inlet pipe 3 by an external delivery pump.
