Description

Civil light hydrocarbon liquid fuel medium pressure furnace

The utility model relates to a stove, in particular to a civil light hydrocarbon liquid fuel medium-pressure stove.

my country has a vast territory, a large population, and a small amount of energy resources per capita. Only by rationally developing various available energy resources and forming multi-energy complementarity can we meet the growing demand for high-quality fuel in rural areas. Light hydrocarbons are by-products of the petrochemical industry, and most of them are wasted at present. The full development and utilization of light hydrocarbon civil fuels is one of the effective ways to improve resource utilization. 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, in addition to having certain quality standards for light hydrocarbon fuels, the above-mentioned problems must also be completely solved in the design of the stove structure.

Many Chinese patents have made innovative designs for liquid fuel stoves, such as: "A new type of high-efficiency liquid fuel stove" (ZL97240565) is mainly composed of a stove shell, a main oil tank, a liquid fuel gasification device, a pressure balance tube, a gas It is composed of throttling and pressure regulating valve, filtering and pressure buffering device, furnace head, fire distributor, auxiliary oil tank, electronic igniter, preheating combustion tray and pressure negative feedback device, and is characterized in that the liquid fuel used in the stove is vaporized The device is composed of two or more connected gasification chambers, and its structure is relatively complicated, so it is difficult to put it into civilian use. Combustion box and quantitative dripper are arranged in " synthetic liquid fuel stove " (ZL97229644). "Liquid fuel stove" (ZL97204039) also has a combustion box, a preheating plate and the like. "Liquid Fuel Burner" (ZL96242499), "Synthetic Liquid Fuel Burner" (ZL96239269), "Liquid Fuel Stove" (ZL95232153), Liquid Hydrocarbon Mixed Gas Burner "(91107537, as seen), "Synthetic Liquid Gasification "Stoves" (ZL90217406, terminated), "New Liquid Fuel Stoves" (ZL87205158, terminated), etc., have their own advantages, and the occasions used and the requirements for liquid fuels are different, but they have not been widely used at present. for civilian use.

The task of this utility model is to provide a medium-pressure furnace with light hydrocarbon liquid fuel for civilian use, which does not consume electricity, does not need a fan to support combustion, has a stable combustion condition, is not affected by the climate, and has good safety. It is especially suitable for hotels, large food stalls and industrial furnaces. field.

In order to accomplish the above tasks, the solution adopted by the utility model is: a medium-pressure furnace with light hydrocarbon liquid fuel for civilian use, including a furnace seat, a burner head, a burner, an electronic igniter, a connecting pipe, etc., a burner, a The primary preheating pipe and the secondary preheating pipe are connected to the liquid pressure reducing valve through the connecting pipe before the liquid direction switch, and then communicated with the atomization device in the burner through the connecting pipe, and the primary preheating pipe is connected to the separation device through the connecting pipe After that, it 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.

The utility model is very convenient to operate: open the liquid direction pressure reducing valve, the light hydrocarbon liquid fuel enters the liquid direction switch through the connecting pipe under pressure, opens the liquid direction switch, and the fuel enters the furnace head, and is refined by the atomization device and contacts with normal temperature to produce certain The gas carries part of the liquid into the primary preheating tube, leaving the remaining liquid under the burner. The gas and part of the liquid enter the separation device instantaneously under pressure. , the gas carries part of the liquid and flows to the secondary preheating pipe through the connecting pipe. After the fuel comes out of the secondary preheating pipe, it has been fully vaporized, and the electronic igniter is turned on 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. The utility model is fully applicable to No. 1 and No. 2 light hydrocarbon liquid fuels in the standards issued by the Ministry of Agriculture by mixing the liquid gasification with the third air and preheating the second time, and achieves high-efficiency combustion. If the room temperature is not enough to generate a certain amount of gas, you can put a piece of paper ball on the burner head to ignite and accelerate the gasification when you use it for the first time in a day. The utility model does not consume electricity during use, does not need a fan to support combustion, and is not affected by the climate; since the combustion is completely gas, the combustion condition is stable and the safety is good, and it can be widely used in hotels, hotels and industrial fields.

The utility model and its positive effects will be further described below in conjunction with the embodiments and accompanying drawings.
