A kind of methanol gasifying device
Technical field
The invention belongs to specifically design a kind of apply in heating system using methanol as the heating system technical field of fuel
Methanol gasifying device.
Background technique
Using methanol as the heating system of fuel, it is to utilize methanol and air under the effect of the catalyst, occurs aphlogistic
Catalyst combustion reaction simultaneously discharges heat, which can pass in the air around heating system to achieve the effect that heating, also
Thermal medium can be passed to achieve the effect that heating, the process is environmentally protective, and heating efficiency is high.
The factor for influencing catalysis ignition temperature is mainly the supply of catalyst type and ratio, methanol gas and air
Amount, when methanol gas or the supply amount deficiency of air, catalysis reaction not exclusively, is also easy to produce the toxic gases such as formaldehyde, CO;At present
Common be arranged is that methanol slot is arranged in the bottom of catalysis slot, and catalysis slot outer wall is equipped with air inlet, and the methanol in methanol slot is certainly
So enter catalysis slot after volatilization, and with the air that enters from air inlet, catalyst combustion reaction occurs under the effect of the catalyst;?
In the technical solution, the amount of vaporization of methanol is influenced by temperature larger, and the supply of air capacity is also unstable, and air need to be into
Enter in catalyst, then reacted with catalysis is carried out after methanol mixing, it is difficult to ensure that the uniform admixture of methanol and air, easily leads
Methanol oxidation is caused not exclusively to evaporate into the outside air of heating system;Meanwhile in the catalysis of methanol reaction, the stream of air
Speed is answered relatively slow, is reacted so that with it catalysis can occur for methanol completely, and in the technical program, the flow velocity of air equally can not
Control, and will appear methanol and react incomplete phenomenon.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of methanol gasifying device, passes through air stone, cotton layer and air
The setting of supply part, accelerates the evaporation rate of methanol, and guarantees that methanol can uniformly be mixed with the air of sufficient amount, so that first
Catalysis reaction of the alcohol in catalysis slot is more complete, efficiently reduces the generation of the toxic gases such as CO, formaldehyde.

Air molecule is segmented by air stone and is exported to methanol trench bottom by trench bottom, and the air after being subdivided can be from methanol gasifying
Trench bottom evaporates into top, and in this process, methanol and air adsorption are combined into mixed gas, and from the bottom of methanol gasifying slot
Top is evaporated into, the gasification of methanol is thereby accelerated;The air of another way is transported to above the cotton layer in methanol gasifying slot,
It is mixed with the methanol evaporated into above cotton layer, to guarantee to can avoid in mixed gas containing amount of oxygen needed for catalysis reaction
Methanol causes catalysis to react incomplete phenomenon generation because determining;
(2) cotton fiber in the present invention has stronger moisture absorption and permeability, the mixed methanol of methanol gasifying trench bottom
With air in uphill process, resistance and fine and closely woven space by cotton fiber layer by layer increase the mixed of methanol and air
Conjunction degree;Meanwhile the absorption by cotton layer to methanol, it can effectively prevent methanol gasifying slot after collapsing the phenomenon that methanol outflow
Occur;
(3) diameter of the diameter of the efferent duct B in the present invention less than efferent duct A easily condenses once again because methanol is in gasification
At methanol liquid, after methanol liquid condenses in efferent duct A, it is not easily accessible in efferent duct B, flows back into methanol gasifying down mostly
In slot;Even if there is only a few methanol liquid to enter in efferent duct B, because the length of efferent duct B is much larger than the length of efferent duct A, and
Efferent duct B is placed perpendicular to horizontal plane, and the ascending path of methanol liquid is longer, the effect in uphill process, vulnerable to its gravity
And decline, and be back in methanol gasifying slot;In addition, efferent duct B is made by copper, copper has excellent heating conduction, can help
Methanol in pipeline fully absorbs extraneous heat and guarantees that it is in the state of gasification, effectively prevent liquid methanol to enter and urges
Change in slot, and influences the catalytic activity of catalyst.
