Description

Medium-pressure furnace for light hydrocarbon liquid fuel with gasification and heat-supporting automatic control device

The utility model belongs to light hydrocarbon liquid fuel stoves, in particular to a light hydrocarbon liquid fuel medium-pressure furnace with a gasification heating aid automatic control device.

Light hydrocarbon fuels mainly consist of C5-C7, exist in liquid state, have low density and fast evaporation speed, which is different from liquefied petroleum gas which is widely used now. When light hydrocarbon liquid fuel is used as domestic fuel, it must be preheated and gasified before the fuel enters the stove burner, and then mixed with air for combustion. Due to the complex composition of light hydrocarbon fuels and large performance changes, problems such as insufficient combustion, smoke, and carbon deposits often occur during use. To solve these problems, except that the light hydrocarbon fuel must have a certain quality, these problems must also be completely solved in the stove structure design. For this reason, the applicant has designed a "civilian light hydrocarbon liquid fuel medium-pressure furnace" (ZL 99 2 45703.3), which includes a furnace base, a furnace head, a burner, an electronic igniter, a connecting pipe, etc., and is characterized in that the furnace The burner is placed in the middle of the head, the primary preheating pipe, and the secondary preheating pipe. Pass through the connecting pipe to the separation device, pass through the connecting pipe to the gas direction switch, and communicate with the secondary preheating pipe through the connecting pipe, lead the connecting pipe from the secondary preheating pipe to the nozzle, and the nozzle sprays to the burner; and then design a "Civil Light Hydrocarbon Liquid Fuel Atmospheric Medium Pressure Furnace" (ZL 99 2 56527.8) has achieved positive results and can be popularized and applied. But there are also shortcomings, that is, there are the disadvantages of slow start in winter when the temperature is low, and the disadvantages of using paper balls to ignite and support combustion and inconvenient operation, which need to be further improved and improved.

The task of the utility model is to provide a medium-pressure furnace for light hydrocarbon liquid fuel with a gasification and heat-supporting automatic control device, which is not only more convenient to operate, but also can be quickly started under low temperature conditions in winter.

In order to accomplish the above tasks, the solution adopted by the utility model is: a light hydrocarbon liquid fuel medium-pressure furnace with a gasification heat-supporting automatic control device, including a furnace base, a furnace head, a burner, an electronic igniter, a connecting pipe, etc. The burner is placed in the middle of the furnace head, the primary preheating pipe, and the secondary preheating pipe. The pipe passes through the connecting pipe to the separation device, then passes through the connecting pipe to the gas direction switch, and then communicates with the secondary preheating pipe through the connecting pipe, and connects the connecting pipe from the secondary preheating pipe to the nozzle, and the nozzle sprays to the burner. It is characterized by the separation device There is also a heating tube inside, a heating tube is installed in the nozzle, and an automatic controller is installed between the two heating tubes and the power supply.

Compared with the prior art, the utility model has the following positive effects:

1. The operation is more convenient. Open the liquid pressure reducing valve, the light hydrocarbon fuel enters the liquid switch through the connecting pipe; open the liquid switch, the fuel enters the burner, and the atomization device refines and contacts with room temperature to generate a certain amount of gas to carry part of the liquid into the primary preheating tube. The remaining liquid is left under the burner, and the gas and part of the liquid enter the separation device instantaneously under pressure; the heating tube in the separation device acts as a heat-assisted gasification function, so that the fuel is gasified in the separation device, and the gas direction switch is turned on through the connecting pipe. The gas carries part of the liquid and flows to the secondary preheating pipe through the connecting pipe. If the gas becomes liquid again in the low temperature connecting pipe, it will flow back to the nozzle and be vaporized by the heating pipe again. Therefore, when the fuel comes out of the secondary preheating pipe, it is already Get fully gasified. Turn on the electronic igniter and ignite to ignite. After combustion, the temperature of the furnace head rises to a high level, the gasification speed is accelerated, and the liquid in the bottom of the furnace is also gasified and burned. Therefore, the operation is very convenient.

2. Not affected by low temperature. Because the separation device is also equipped with a heating tube, the nozzle is equipped with a heating tube, and an automatic controller is installed between the two heating tubes and the power supply. The first heating tube is heated and vaporized, and the gas coming out of the secondary preheating tube is easy to ignite and ignite. Therefore, no matter it is winter, it can also be ignited quickly.

3. Automatically turn off the power. When the gasification temperature reaches the self-control temperature, the self-controller will automatically close and disconnect the circuit.

4. The combustion condition is more stable. Because all the gas comes out of the secondary preheating tube, the combustion condition is more stable, the safety is good, and it is easier to popularize and apply.

5. Using the utility model, the No. 1 and No. 2 fuels stipulated in the standard NY 313-1997 "Light Hydrocarbon Civil Fuel" issued by the Ministry of Agriculture can be efficiently burned, which has significant economic and social benefits.
