Description

Methanol gasifying machine
Technical field
The utility model relates to equipment for gasification, relates in particular to a kind of methanol gasifying machine.
Background technology
The flame temperature of methyl alcohol reaches as high as 1100 DEG C of left and right, if flame temperature can reach 1200 DEG C of left and right under oxygen enrichment fully burns, and the temperature of flame core, internal flame and flame envelope increases successively, when flame envelope sufficient combustion, temperature is the highest, want to make that the combustion flame temperature of methyl alcohol is higher should shift to an earlier date preheating, after the adjusting methyl alcohol of science and the ratio of oxygen, burning will be very abundant in addition, and after the methyl alcohol under rich oxygen content fully burns, its fuel value and flame temperature can increase by 70% left and right.Tradition methyl alcohol burning is liquid burning, and burning very insufficient greatly reduces the performance of calorific value, and taste excitatory produces, and has both been unfavorable for environmental protection, is difficult to again make methyl alcohol to be used as the industrial combustion energy and popularizes.Gaseous methanol after vaporization both can burn separately and also can carry out blending with imflammable gas such as liquefied gas, natural gas or oxygen, further bring into play to greatest extent the burning benefit of methyl alcohol, its calorific value can compare favourably with natural gas completely, and its calorific value exceedes natural gas even to a certain extent.To be used for substituting optimal clean, the environmental protection new forms of energy of the industrial fuels such as liquefied gas, diesel oil, natural gas and coal 21 century, greatly reduce the production cost of enterprise, be using at present diesel oil, liquefied gas, coal, etc. as the save energy and reduce the cost first-selected energy-saving equipment of comprehensive transformation of the factory of main fuel and catering industry, can be the operating cost of enterprise's reduction by 35%-10% in various degree.After methanol gasifying, burn and need have gasifying machine to complete.The existing method that methyl alcohol is gasified is that the method that adopts heating to boil gasifies, and corresponding equipment for gasification is the structure of heating boiling type.As in China Patent No. being 032720823, Granted publication day be Augusts 25 in 2004 day, be called the equipment for gasification that discloses a kind of boiling type in the patent document of " a kind of light hydroxyl gasification installation ", this equipment for gasification heats, makes liquid to produce to the liquid that flows through coil pipe by conduction oil to gasify.This equipment for gasification has the following disadvantages while being used for gasification of methanol: gasification methyl alcohol can produce boiling phenomenon and cause in methanol gas containing methanol liquid, is also that methanol gasifying is not thorough; Conduction oil easily produces fuel injection event; Water in methanol gas can not be isolated.
Utility model content
The first object of the present utility model aims to provide the sufficient methanol gasifying machine of a kind of methanol gasifying, has solved the problem that existing equipment for gasification can not make methyl alcohol fully gasify.
The second object of the present utility model is intended to further improve on the basis of the first object and a kind ofly can prevents that conduction oil from producing the methanol gasifying machine of fuel injection event, has solved the existing gasification installation heating by conduction oil and can produce the problem of conduction oil fuel injection event.
The 3rd object of the present utility model be intended to further provide on the basis of the first object a kind of can be by isolated the liquid water in methanol gas methanol gasifying machine, can not be by isolated water problem while having solved existing equipment for gasification gasification of methanol.
Above technical problem solves by following technical proposal: a kind of methanol gasifying machine, comprise heat conduction fuel tank, be positioned at the gaseous methanol outlet of heat conduction fuel tank outside, be positioned at several fountain vaporizers that are connected in series of heat conduction fuel tank and the methyl alcohol front pump that outlet links together with heat(ing) coil one end, in described heat conduction fuel tank, be provided with heater and heat(ing) coil, described fountain vaporizer comprises that gasification chamber and one end are located in the shower in gasification chamber, the inner surface of described gasification chamber forms gasification face, described gasification chamber is provided with vaporizer outlet, one end that described shower is positioned at outside gasification chamber is provided with vaporizer entrance, the part that is positioned at gasification chamber is provided with spray orifice, the vaporizer entrance of first fountain vaporizer in described fountain vaporizer links together with the other end of described heat(ing) coil, the vaporizer outlet of last fountain vaporizer links together with described gaseous methanol outlet.When use, conduction oil is attached in heat conduction fuel tank, by heater, conduction oil is heated, liquid methanol enters heat(ing) coil and by heat-conducting oil heating under the effect of methyl alcohol front pump, then enter shower and spray on the inner surface (face gasifies) of gasification chamber through vaporizer import, gasification chamber is because the heating that is subject to conduction oil is in hot state, methyl alcohol on the gasification face that is sprayed onto is vaporized, in spray process, may cause methyl alcohol to have part not have vaporized phenomenon to produce owing to not encountering the factors such as heat that gasification face or gasification face provide is inadequate, now in the time entering next stage fountain vaporizer, methyl alcohol is further gasified and is improved temperature, finally making methanol gas enter combustion furnace with the condition of high temperature from gas methyl alcohol outlet outflow burns.Some fountain vaporizers of the application comprise the scheme of only having a vaporizer.Two or more fountain vaporizers are connected in parallel and are equal to a fountain vaporizer, and therefore several fountain vaporizers are adopted to series connection, mode series-parallel connection arranged side by side is also the application's the technical scheme being equal to together.
The utility model also comprises the heat conduction chamber that is positioned at heat conduction fuel tank top, described heat conduction chamber diapire inner surface is inclined, between described heat conduction chamber and heat conduction fuel tank, be communicated with by the first oil pipe and the second oil pipe, the upper port of described the first oil pipe is positioned at that heat conduction chamber diapire is high-end, lower port is positioned at heat conduction fuel tank roof, and the upper port of described the second oil pipe is positioned at heat conduction chamber diapire low side, lower port and is positioned at the below of the lower port of the first oil pipe.Can effectively prevent that conduction oil from producing fuel injection event.When conduction oil quality bad and produce when fuel injection event, oil enter through the first oil pipe heat conduction chamber by cooling go to boil, then dirty and in the second oil pipe is back to heat conduction fuel tank rapidly, thereby play the effect that prevents oil spout.
As preferably, described the first oil pipe is inclined.Can effectively prevent that conduction oil from producing false fuel injection event.
