Abstract

The utility model relates to a twice vaporization methanol synthesizing stove. A first time vaporizing tube and a second time vaporizing tube are arranged on the bottom face and the top face of a burner to provide twice vaporizations for the liquid fuel to synthesize methanol. The utility model has the advantages of good burning effect, high heat efficiency, convenient family and field use, light weight, and safety.

Description

Twice gasified synthetic mathane stove

The utility model belongs to the kitchener tool, especially a kind of stove and accessory that can make twice vaporization of liquid fuel synthesizing methanol.

At present, because the in short supply and price of fuel such as artificial coal gas, natural gas, liquefied petroleum gas is higher, people are developing the stove and accessory that methyl alcohol is made fuel, as Chinese patent 88211632.0 " Carbinol stove ", Chinese patent 91207309.8 " methanol fuel stove ", Chinese patent 91104247.4 " infrared methanol stove " etc.But these stove and accessorys all are that the combustion efficiency and the thermal efficiency are not very good with the liquid fuel after-combustion of once vaporizing, and in addition, in the process of using, exist the possibility that methanol poisoning takes place.

The purpose of this utility model provides a kind of special use synthesizing methanol, and vaporization effect is good, thermal efficiency height, and the stove and accessory of methanol poisoning can not take place.

A generating tube 9 of the horizontal positioned of a U type is set in the combustion chamber 4 of the utility model below burner 5, a secondary vaporizing pipe 6 is set on burner 5 simultaneously.A mixing control valve 12 is installed on fuel tank 15, and its D end has a compressed air inlet 24 and a fuel skirt 22.Mix fuel and compressed air that control valve 12 enters a generating tube 9 in can fuel metering case 15, regulating handle 10 is used for regulate fuel flow, and regulating handle 14 is used for regulating compressed air air pressure.No. one time generating tube 9 one ends are connected with mixing control valve 12B hole, and the other end is connected with the fuel inlet 26 of secondary vaporizing pipe 6.During the stove and accessory operate as normal, the synthesizing methanol in the fuel tank 15 is through skirt 22, control valve 12, enters generating tube 9 and secondary vaporizing pipe 6, by behind the nozzle 3, enters spray chamber 1, enters combustion chamber 4 then, burning on burner 5 at last.Be provided with nozzle 3 at secondary vaporizing pipe 6 one ends, the inside is provided with metering pin valve 7, by regulating handle 8, can regulate the flow through methyl alcohol behind the secondary vaporizing of nozzle 3, i.e. the size of flame on the burner 5.Have an air intlet 2 on spray chamber 1, an available catch is regulated the import aperture, can regulate the air capacity that enters combustion chamber 4.On oil plant case 15, be provided with charge valve 18, safety valve 17, bunkering port 23, Pressure gauge 16 and support 19.The fuel draining hole 20 of spray chamber 1 bottom is used for discharging residual small amount of fuel in the combustion chamber 4.

The utlity model has advantages such as burning is desirable, easy to use, volume is light, safe and reliable, can be used as at home and the field stove and accessory.

Fig. 4 is secondary vaporizing pipe 6 position views.

Wherein, 1 spray chamber, 2 air intlets, 3 nozzles, 4 combustion chambers, 5 burners, 6 secondary vaporizing pipes, 7 metering pin valves, 8 regulating handles, No. 9 generating tubes, 10 regulating handles, 11 metering pin valves, 12 mix control valve, 13 metering pin valves, 14 regulating handles, 15 fuel tanks, 16 Pressure gauges, 17 safety valves, 18 charge valves, 19 supports, 20 fuel draining holes, 21 liquid levels, 22 skirts, 23 bunkering ports, 24 compressed air inlet, 25 support covers, 26 fuel inlets.

Below in conjunction with accompanying drawing use of the present utility model is described further.In fuel tank 15, add an amount of synthesizing methanol.Add 2kg/cm through charge valve 18 ²Pressure.Open regulating handle 10,14,8, the fuel on the ignition combustion device 5.Along with the raising of burner 5 temperature, a generating tube 9 below it is heated, and makes fuel that once vaporization take place.Fuel enters hot secondary vaporizing pipe 6 secondary vaporizing takes place again.Adjust regulating handle 8,10,14, can obtain required flame size and temperature.When stopping using stove and accessory, close regulating handle 10,14,8 and get final product.
