Description

Technical Field

[0001] The utility model relates to the technical field of methanol filtering, in particular to a methanol clean filtering device. Background Art

[0002] Methanol, also known as hydroxymethane, wood alcohol or wood spirit, is an organic compound and the simplest saturated monohydric alcohol. Modern methanol is manufactured directly from an industrial process of catalysis of carbon monoxide, carbon dioxide and hydrogen. There are many physical methods widely used for desulfurization and decarbonization, such as low-temperature methanol washing (Rectisol, transliterated as Rectisol method) and NHD (polyethylene glycol dimethyl ether) method. The low-temperature methanol washing technology (rectisol) uses methanol organic solvent as an acid gas absorbent. Under low temperature conditions, it uses the physical property of methanol's great solubility in acid gases such as CO2, HS, COS, etc. to selectively absorb H2S, CO2 and various organic sulfur impurities in the raw gas. Some fine impurities will be generated before and during the operation of the low-temperature methanol washing device, so they need to be filtered through a filter device.

[0003] Patent announcement number CN209049194U discloses a methanol filtering device, including a filter tower, a cavity is provided inside the filter tower, a methanol outlet is provided at the top of the filter tower, a methanol material inlet is provided at the side of the filter tower, a filter element is provided in the cavity above the methanol material inlet, a first flushing pipe is provided at the top of the filter tower on the left side of the methanol outlet, the first flushing pipe is penetrated into the interior of the filter tower and bent to the right side to provide a second flushing pipe, a plurality of shower nozzles are regularly provided at the bottom of the second flushing pipe, a flushing box is connected to the other end of the first flushing pipe, a nitrogen gas pipe is also provided at the top of the filter tower on the right side of the methanol outlet, and a nitrogen box is connected to the outer end of the nitrogen gas pipe.

[0004] Although the prior art CN209049194U has many benefits during use, it still has the following problems: it lacks a protective structure for the air jet pipe and the liquid spray pipe, which causes some impurities to contact the nozzle, causing the nozzle to be blocked and affecting the smoothness of backwashing.

Then, hot desalted water is ejected through the three-way valve, connecting pipe, connecting pipe and ejection pipe to dissolve and clean the inside of the filter element, thereby ensuring the cleanliness of the filter element. After the connecting block is reset, the sealing gasket blocks the support plate and blocks and protects the ejection pipe.

[0008] Preferably, the outer wall of the lower end of the connecting pipe is plugged with a circular array of spray pipes, and the spray pipes are connected to the lower end of the support plate. The medium is sprayed to the upper end of the filter element through the spray pipes.

[0010] Preferably, a discharge pipe is plugged and installed on one side of the outer wall of the upper end of the shell, and the discharge pipe is connected to the inside of the shell. The filtered material is discharged through the discharge pipe.

[0011] Preferably, a sewage pipe is plugged and installed on one side of the outer wall of the lower end of the shell, and the sewage pipe is connected to the inside of the shell. The cleaned waste water is discharged through the sewage pipe.
