The raw material of phenolic resin and amino resins, secondly for production polyformaldehyde, trimethylolpropane, pentaerythrite, methenamine, pyrrole
The chemical products such as pyridine and isoprene, formaldehyde also act as synthetic perfume, synthesis explosive, synthesis chelating agent, additive synthesis and
Synthesize important intermediate etc..
Industrial production formaldehyde uses methanol oxidizing process more.By theoretical calculation, its product for the mixture of formaldehyde and water (mole
Ratio 1:1).Since the vapour pressure of formalin is relatively low and formaldehyde and water form azeotropic mixture, separation and purification are prepared without water beetle
Aldehyde high energy consumption.The core equipment of Formaldehyde Production is oxidation reactor, its capital equipment has evaporator, superheater, purifier, sieve
Thatch wind turbine and absorption tower etc..Impurities are more in crude carbinol used in the process of production formaldehyde, needed in actual production
Methanol is pre-processed, so that the purity higher in methanol, allows it to produce the formaldehyde of higher degree.Existing first
Alcohol purifier is mainly to be cleaned by placing material such as activated carbon of absorption impurity etc. in the device to methanol, due to device
Design unreasonable, methanol gas is mainly from the middle part of device by causing methanol gas not connect fully with materials such as activated carbons
Touch, the clean-up effect of methanol is undesirable, and purification efficiency is relatively low.
Utility model content
In view of this, the purpose of this utility model is to provide the device that a kind of purifying methanol prepares formaldehyde, to solve methanol
Purifier setting is unreasonable during production formaldehyde causes the relatively low and existing technical problem of purification efficiency.
The utility model solves above-mentioned technical problem by the following technical programs：
A kind of purifying methanol prepares the device of formaldehyde, including babinet, and air inlet and gas outlet are respectively equipped with tank ends,
Box house is provided with purify cavity, and purifying layer is equipped with purify cavity, further includes the flow-disturbing being arranged between air inlet and purifying layer
Plate, is equipped with spoiler on side of the spoiler close to air inlet.
The purifying layer include set gradually from activated carbon filter layer from air inlet to gas outlet direction, rock wool filter layer with
And fibrous filter layer.
The upper end opening of the babinet, opening are equipped with dismountable head cover.
The air inlet has the hollow sleeve of hollow cavity by air inlet pipe connection one, and magnetite is equipped with hollow sleeve.
The both ends of the hollow sleeve are equipped with nipple.
The spoiler is cylinder.
The spoiler is equipped with several ventholes.
The spoiler is made of stainless steel material.
The spoiler is made of stainless steel material.
The air inlet is funnel shaped.
The beneficial effects of the utility model are：By setting spoiler in the purify cavity of purifier, and in flow-disturbing
Spoiler is set on plate, effectively the methanol gas entered from air inlet can spread out, make methanol gas more uniform
By purifying layer, increase methanol gas and effective contact area of purifying layer, so as to improve the efficiency of purification, improve purified
The purity of methanol, is conducive to subsequent production.

Embodiment
In order to facilitate the understanding of those skilled in the art, the utility model is done into one below in conjunction with embodiment and attached drawing
The description of step.Embodiment is only to the utility model for example, not being the restriction to the utility model, in embodiment not
The step of illustrating is prior art, is not described in detail herein.
Embodiment one
As shown in Figure 1, a kind of purifying methanol prepares the device of formaldehyde, including babinet 2, be respectively equipped with 2 both ends of babinet into
Gas port 1 and gas outlet 12, are provided with purify cavity 11 inside babinet 2, and purifying layer 7 is equipped with purify cavity 11, in air inlet 1 with purifying
Spoiler 5 between layer 7, spoiler 4 is provided with 5 side of spoiler close to air inlet 1.Open the upper end of the babinet 2
Mouthful, opening is provided with dismountable head cover 3, and dismounting and change is carried out to purifying layer 7 to facilitate.The air inlet 1 passes through air inlet
Pipe connection one has the hollow sleeve 13 of hollow cavity 15, and magnetite 16 is provided with hollow sleeve 13.
The purifying layer 7 includes activated carbon filter layer 8, the rock wool mistake set gradually from air inlet 1 to 12 direction of gas outlet
Filtering layer 9 and fibrous filter layer 10.
The both ends of the hollow sleeve 13 are equipped with nipple 14, convenient to be threadedly coupled with conveyance conduit, and conveniently tear open
Unload and the impurity in cleaning pipe.
The spoiler 5 is cylinder, and methanol gas touches spoiler after air inlet 1 is entered in purify cavity 11
Spoiler 4 on 5, methanol gas are spread out, and avoid methanol gas from only passing through and purify cavity 11 from the middle part of purify cavity 11
The gas flow passed through close to cavity wall position is relatively fewer, so as to limit coming into full contact with for methanol gas and purifying layer 7, causes only
It is undesirable to change effect.Spoiler 4 is set on spoiler 5, effectively the methanol gas entered from air inlet 1 can scatter
Come, make methanol gas more uniformly by purifying layer 7, increase methanol gas and effective contact area of purifying layer 7, so as to carry
The efficiency of height purification.
The spoiler 5 is equipped with several ventholes 6, so that methanol gas is by the way that venthole 6 is on spoiler 5
Distribution situation is middle rare, and 5 edge of spoiler is relatively intensive, the reason is that the throughput of middle part is larger, venthole 6 compared with
It is few, can be less from the gas flow wherein passed through, so that gas disperses to surrounding, reach and be uniformly dispersed by purifying layer 7
Effect.
The spoiler 5 is made of stainless steel material, and stainless steel material will not produce burn into spot corrosion, corrosion or abrasion,
Ensure the service life of spoiler 5.
