Problems solved by technology
Although the gas filter in the prior art can remove impurities or particles in the gas and ensure a certain purity of the gas entering the reactor, it cannot completely protect the silver catalyst from contamination, and sometimes harmful impurities in the gas will be brought into the system. It is very easy to poison the catalyst and lose its activity

The invention relates to a multi-component gas filter, belonging to the field of gas filters. The multi-component gas filter mainly comprises a shell, a diverting unit, an ultra-fine glass fiber filter unit and supporting legs, wherein the shell is provided with a gas inlet, an access port, an explosion-proof port, a temperature and pressure detecting port, a liquid discharging port, a sewage outlet, a gas outlet, etc.; the supporting legs are welded to the shell; the diverting unit is connected with the gas inlet inside the shell; the ultra-fine glass fiber filter unit is installed in the shell; and filtered multi-component gas is output from the gas outlet of the shell. The multi-component gas filter provided by the invention has the advantages of simple structure, small size, good separation effect and small resistance, and is widely applied to the production of formaldehyde.
Description
technical field [0001] The invention relates to a gas filter, in particular to a multi-element gas filter. Background technique [0002] In addition to evaporators, superheaters, flame arresting filters, Roots blowers, absorption towers, and gas filters for formaldehyde production equipment. Although the gas filter in the prior art can remove impurities or particles in the gas and ensure a certain purity of the gas entering the reactor, it cannot completely protect the silver catalyst from contamination, and sometimes harmful impurities in the gas will be brought into the system. It is very easy to poison the catalyst and lose its activity. Contents of the invention [0003] In view of the above situation, the present invention discloses a multi-element gas filter. The technical scheme adopted in the present invention is: a multi-element gas filter is mainly composed of a casing, a flow diversion unit, an ultrafine glass fiber filter unit and a supporting foot. The casi...
