Abstract
The invention relates to a methyl alcohol filter for methyl aldehyde production. The methyl alcohol filter comprises a shell with a hollow inner cavity. The upper end of the shell is open, a sealing cover is arranged in the open position of the upper end of the shell and is provided with a gas outlet, and a gas inlet is arranged on the lower portion of the shell. A sewage outlet is arranged at the bottom of the shell. A first annular magnet, an activated carbon filtering and adsorbing layer, a filter cotton layer and a second annular magnet are sequentially arranged in the hollow inner cavity from top to bottom. The first annular magnet is spaced from the activated carbon filtering and adsorbing layer by a preset distance, and the second annular magnet is spaced from the filter cotton layer by a preset distance. When methyl alcohol is led into the filter from the gas inlet and discharged from the gas outlet, sulfide, other impurities and iron in the methyl alcohol can be removed, and therefore the methyl alcohol quality can be improved in the methyl aldehyde production process, the cleanliness of a silver catalyst can be better protected, and the service life of the silver catalyst can be guaranteed.
Description
Technical field
The invention belongs to Formaldehyde Production technical field, be specifically related to a kind of methanol used for formaldehyde production and filter
Device.
Background technology
Formaldehyde is a kind of colourless, has the gas of strong excitatory abnormal smells from the patient, soluble in water, alcohol and ether,
Formaldehyde is gaseous state at normal temperatures, occurs the most as an aqueous solution, and formaldehyde is a kind of important organic
Raw material, is mainly used in synthetic.Along with industrial expansion, formaldehyde is also got over as the purposes of raw material
Come the most extensive, such as synthetic fibers, leather industry, medicine, dyestuff etc..Formalin has sterilization
And antiseptic power, biological sample processed can be soaked, its weak solution (0.1-0.5%) agriculturally can be used to soak
Kind, to seed disinfection.
Industrial conventional catalytic oxidation is produced formaldehyde by methanol, and formaldehyde is industrially by methanol
Catalysis oxidation preparation, therefore the purity of methanol is directly connected to the quality of products made thereby, by natural gas
The methanol produced with Coal Chemical Industry, containing the impurity of trace, these impurity are difficult to detect, special
It not that in thick alcohol, impurities is more, accordingly, it would be desirable to methanol is carried out pretreatment, so that in methanol
Purity higher, thus improve the quality of production of formaldehyde, but at present along not having a kind of effect preferable
Methanol filtration system.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem and a kind of methanol used for formaldehyde production is provided
Filter.
For achieving the above object, the present invention is by the following technical solutions:
A kind of methanol filter used for formaldehyde production, including a housing with hollow cavity, described shell
The upper end open of body, is provided with sealing lid at described upper end open, described sealing covers and is provided with gas outlet,
The bottom of described housing is provided with air inlet, and the bottom of described housing is provided with sewage draining exit, described hollow
Inner chamber is sequentially provided with first annular Magnet, active carbon filtration adsorption layer, filter cotton layer from top to bottom
And second annular magnet, described first and second annular magnet adsorbs with described active carbon filtration respectively
Layer, filter cotton interlayer are every predeterminable range.
Described active carbon filtration adsorption layer includes a web plate, described web plate is separated by filter cloth and sets
There is multilamellar active carbon particle.
Described first and second annular magnet keeps at a certain distance away set with upper end and the lower end of described housing
Put.
Described first and second annular magnet can effectively remove the iron tramp in methanol, described activated carbon
Filtration Adsorption layer and filter cotton layer can effectively remove the sulfide in methanol and chloride etc.
Affect the impurity of Formaldehyde Production quality, by above-mentioned multistage filtering and absorption, it is ensured that filter and inhale
The purity of attached methanol is ensured effectively.
The present invention passes through at a housing with hollow cavity, and the upper end open of described housing is described
Being provided with sealing lid at upper end open, described sealing covers and is provided with gas outlet, on the bottom of described housing
Being provided with air inlet, the bottom of described housing is provided with sewage draining exit, depends on from top to bottom in described hollow cavity
Secondary it is provided with first annular Magnet, active carbon filtration adsorption layer, filter cotton layer and the second annular magnet,
Described first and second annular magnet respectively with described active carbon filtration adsorption layer, filter cotton interlayer every in advance
If distance, when methanol being passed through from air inlet and discharging from described gas outlet, can have in methanol
The impurity such as sulfide and ferrum remove, thus ensure that and formaldehyde production can improve methanol matter
Amount, preferably protects clean property and the service life of silver catalyst.
Accompanying drawing explanation
