Combined filtering equipment for methanol production

Abstract

The invention discloses combined type filtering equipment for methanol production, and the equipment comprises a filtering bin and a recycling bin; locking type flange structures are arranged at two ends of the filtering bin, the locking type flange structures are connected with a methanol system pipeline, the recycling bin is arranged below the filtering bin, and a combined type filtering mechanism is arranged in the filtering bin; and a reverse cleaning mechanism is disposed between the filtering bin and the recycling bin. The filtering bin is connected to a system pipeline through the locking type flange structures, the combined type filtering mechanism is arranged in the filtering bin, impurities in methyl alcohol are filtered and separated through the combined type filtering mechanism, and meanwhile, the reverse cleaning mechanism is arranged on the lower portion of the filtering bin; when cleaning is needed, the locking type flange structures are used for closing the system pipeline, then impurities isolated from the combined type filtering mechanism are reversely impacted down in a reverse cleaning mode, a mixture obtained after re-cleaning is recycled, and the pollution caused by methanol obtained after cleaning is avoided.

Description

technical field [0001] The invention relates to the technical field of methanol processing, in particular to a combined filter device for methanol production. Background technique [0002] Methanol, also known as hydroxymethane, is an organic compound and the simplest saturated monohydric alcohol. It is used in the manufacture of formaldehyde and pesticides, etc., and is used as an extractant for organic matter and a denaturant for alcohol. There are four types of impurities in methanol. They are rust, carbon black and sulfide in the shift gas, and residual dust during installation. The most important impurity is the carbon black in the shift gas. When the system is powered by methanol, these loose iron oxides and iron sulfide will As the methanol circulates throughout the system, it finally deposits in the heat exchanger or places where the flow rate is slow, causing serious blockage of the heat exchanger, reduced heat transfer efficiency, increased resistance, unbalanced s...
