Abstract

The utility model relates to a pre-heating constant temperature gasifier which is composed of a copper pipe outside coated by insulating varnish, wound by a conductive body as an electrode, and then coated by an electrothermal film added by an insulating heat-insulating layer. The utility model can continuously gasify gas liquid. Before going into a heater, the combustible liquid goes through a pre-heater at first. The utility model is also provided with a temperature controller. When the temperature of the pre-heater achieving a fixed value can meet gasifying requirements, the utility model can cut off the electricity supply and can switch on the electricity supply when the temperature is below the fixed value.

Description

Gas combustion automobile preheating type heated constant temperature gasification installation

The utility model relates to preheating type heated constant temperature gasification installation on a kind of gas combustion automobile.

Gas combustion automobile (rock gas, liquid gas) is a kind of desirable " green " traffic tool because pollution is few, and it will substitute the fuel-engined vehicle of existing high pollution.Existing a small amount of automobile has made gas combustion automobile in some big cities of China at present, but it all is to adopt dual-fuel.Being motor when starting working, is to use original oil supply system, automobile running after the stretch journey, when circulating water reaches uniform temperature (about 60 ℃), the driver cuts off oil fuel, changes into liquid gas and makes fuel.This is because circulating water heat at this moment can satisfy the required heat of combustion gas liquid gasification.This device exists following defective: the difficult control of temperature of 1 circulating water, southern, northern, summer, winter temperature was widely different, caused most of drivers to complain that the automobile acceleration is bad.2 complex structures not only have steel cylinder on the car, must keep fuel tank, and fuel combustion vehicle start, damage ratio when travelling at a slow speed it want big during at cruising.

The purpose of this utility model provides a kind of gas combustion automobile preheating type heated constant temperature gasification installation, makes vehicle realize single-fuel (combustion gas).

The purpose of this utility model is to realize like this; Do extraction electrode at the copper pipe outer wall that isolation layer is arranged around upper conductor, coat electric heating film again, and add insulating protective layer, thermosensitive probe is housed on the copper pipe in addition, form heater at the electric heating film skin.The liquid of combustion gas flows through from copper pipe.Before heater, there is one group of crooked copper pipe to be compressed in the metal seat, forms preheater.Preheater is set on the engine casing.The liquid of combustion gas is flowed through earlier and is flowed into heater again after the preheater preheating.

Major character of the present utility model is: adopted heating rapidly, therefore high the and energy low voltage heating electric heating film of the thermal efficiency just can generate heat after the electric heating film energising at once, and the liquid in the copper pipe obtains gasifying rapidly behind the heat, and vehicle just can travel.No longer need to have used the process of vapour with the oil back earlier, realized automotive single one fuel purpose.In order to save limited electric energy on the vehicle, the advanced preheater of combustion gas liquid arrives heater again, motor starts after a few minutes just very hot, preheater is to be set on the engine casing to be integral, also hot at once by thermal conductance effect effect preheater, flow through the also just gasification here of preheater combustable liquid like this.Vaporizer thermosensitive probe temperature has reached predetermined value, just cuts off the electric heating film power supply automatically, and electric heating film is just inoperative.But vehicle can cruising.

Fig. 1 is the novel working principle diagrammatic sketch of this use.1 steel cylinder, 2 preheaters, 3 heaters, 4 temp controllers, 5 motors among the figure.

Fig. 2 is the utility model preheater sectional drawing.6 combustion gas liquid, 7 copper pipes, 8 preheater seats among the figure.

Fig. 3 is the utility model heater sectional drawing.9 thermosensitive probes, 10 temp controllers, 11 leads, 12 thermal insulating layers, 13 electric membranous layer, 14 isolation layers, 15 electrodes, 16 copper pipes, 17 combustible gases among the figure

Below in conjunction with the novel work of this use of description of drawings.Scribble heat-resistant insulating layer 14 on the copper pipe 16, make electrode 15 at copper pipe 16 certain distance two ends around upper conductor, lead 11 connects electrode 15, coats electric heating film 13 again, adds thermal insulating layer 12 in its outside.Load onto thermosensitive probe 9 at copper pipe 16 1 ends, thermosensitive probe 9 links to each other with temp controller 10, and temp controller links to each other with power supply.In copper pipe 16 fronts one group of crooked copper pipe 6 is arranged, it is crushed in the metal seat 7, and metal seat 7 is set on the engine casing.Specifically be to work like this: after opening the automobile starting key, combustible gas liquid flows out in steel cylinder 1, enters heater 3 behind the preheater 2 of flowing through, and also starts working in this while electric heating film 13, because electric heating film 13 is generated heat rapidly.So combustible gas liquid is gasificated into combustible gas 17 in copper pipe 16 at once, motor 5 just can start and microrunning, again because preheater 2 is to be set on the motor 5, motor 5 few minutes of operation back cabinet temperature rise very highly, and preheater 2 also and then raises, and combustion gas liquid 6 has just here gasified owing to having obtained enough heats, and at this moment, thermosensitive probe 9 has also elicited the temperature information that raises, and feeds back to temp controller 10, and temp controller 10 just disconnects electric heating film 13 power supplys.Work waste heat by motor satisfies combustion gas liquid gasification heat like this, circulates benignly.Certainly when preheater 2 temperature are lower than specified value, its energy turn-on power, electric heating film 13 is started working again.Can guarantee that like this heter temperature remains unchanged, guarantee that also entering engines combustible gas fully gasifies.
