Description

Technical Field

[0001] The utility model relates to the technical field of methanol production, in particular to a waste liquid collection device for methanol production. Background Art

[0002] Methanol, also known as hydroxymethane, wood alcohol or wood spirit, is an organic compound and the simplest saturated monohydric alcohol. Methanol is also known as "wood alcohol" and "wood spirit". Modern methanol is produced directly from a catalytic industrial process involving carbon monoxide, carbon dioxide and hydrogen. Methanol production wastewater refers to the distillation residue discharged from the bottom of the distillation tower during the production or utilization of methanol. In industrial production, in order to save finished products, the used methanol wastewater is usually collected and put back into use;

[0003] For example, the Chinese utility model provides a "methanol waste liquid recycling device" with patent number: 201420426981.1. The patent includes a buffer tank, a liquid inlet pipeline, a liquid outlet pipeline, an emptying pipeline and a circulation pipeline. The upper end of the buffer tank is respectively provided with a liquid inlet pipeline and an emptying pipeline. The water outlet of the liquid inlet pipeline and the exhaust port of the emptying pipeline are connected to the buffer tank through a connecting flange. The methanol waste liquid in the buffer tank is continuously circulated through the external circulation pipeline, so that the methanol waste liquids of different concentrations are evenly mixed.

[0004] Although the above document solves the problem of traditional buffer tanks for collecting methanol, the collected methanol waste liquid has different concentrations of methanol because it is collected from multiple systems. If such methanol waste liquid is used directly, the subsequent processing will be more troublesome. However, there is still the disadvantage that the waste liquid mixing method is not simple and efficient enough. The purpose of uniform mixing of the waste liquid cannot be achieved quickly and efficiently by continuously circulating the waste liquid. For this reason, a waste liquid collection device for methanol production is introduced here. Utility Model Content
