Liquid fuel gasifier

Abstract

The invention provides a liquid fuel gasifier which is composed of a gasifying device, a burning device, a sound reducing device, a fire ring, a valve body assembly and a fixed frame. The gasifying device is placed above the burning device and is arranged in the sound reducing device. The burning device is partially or completely arranged in the sound reducing device. The gasifying device is composed of a gasifying pipe, a heat insulation pipe and a gas resistor. The gasifier is structurally characterized in that the gasifying pipe is arranged in the heat insulation pipe, the gas resistor is inserted in the gasifying pipe, the gasifying pipe and the gas resistor are combined and inserted to form a combination piece which is wound to form a spiral spring column body or a conical body, the gasifying pipe is a metal hollow pipe or a non-metal high temperature resistant hollow pipe, the heat insulation pipe is a metal hollow pipe, the length of the gas resistor and the heat insulation pipe is shorter than that of the gasifying pipe, the sound reduction device is of an annular columnar structure or a conical structure, and the sound reduction device is placed in the fire ring and surrounds the gasifying device and the burning device. The liquid fuel gasifier resolves the problem that the liquid fuel is completely gasified, enables burning to be complete, is low in energy consumption, saves energy by over 60% with flame temperature higher than 1200 DEG C, does not require a fan, is complete, convenient, electricity-saving, strong in fire and high in heating speed, simultaneously effectively controls gasifying temperature, resolves the problem of carbon accumulation and changes popularization of the liquid fuel especially alcohol group liquid fuel from ideal to reality.

Description

technical field [0001] The invention relates to gasifiers for catering, commercial, industrial and domestic liquid fuels. Background technique [0002] Stoves and burners are necessary heating tools for households, catering, hot pot restaurants and field operations, and gasifiers are the core devices in liquid fuel stoves and burners. At present, due to the shortage of oil resources, oil refined The shortage of liquefied petroleum gas, coupled with the huge investment and long cycle of natural gas pipeline laying, so the market supply is insufficient and there is a serious shortage; diesel oil and kerosene are not popular because of their high price and serious pollution, so they are banned from use in catering, industry and other industries. In order not to be affected by oil resources, various countries have increased their efforts to develop other alternative energy sources. As a kind of renewable energy, methanol and ethanol have been paid attention to by various countr...

Problems solved by technology

[0003] Among liquid fuels, methanol is low in cost, renewable, and easy to process and refine. It has many advantages of its own, but the alcohol-based liquid fuel mainly composed of methanol also has its own many disadvantages. If there is no good gasifier to match it With cooperation, alcohol-based liquid fuels cannot be popularized because of the low calorific value of alcohol-based liquid fuels, which are liquid at room temperature, not suitable for ordinary stoves, carbon deposits during combustion, etc., which is why more than 20 years have passed , and no alcohol-based liquid fuel has been successfully gasified and combusted

During the combustion process of alcohol-based liquid fuel, when the temperature reaches about 65 degrees, it starts to turn into gas, but when the temperature reaches about 250 degrees, it starts to deposit carbon, which blocks the gasification tube and burner, making it unable to work normally; at the same time, the calorific value is low , if it is not gasified and burned, the energy consumption is high, and there is no promotion value; the flame temperature is low, the firepower is small, and the heating speed is slow; it is liquid, and it is difficult to completely gasify and burn; the combustion is not sufficient, and the exhaust gas emitted after combustion seriously exceeds the standard. The five major problems that plague the normal promotion of alcohol-based liquid fuels are also the root cause of the failure of alcohol-based liquid fuels to be promoted normally. It cannot overcome these problems by changing the formula of alcohol-based fuels, but by changing the combustion method of the stove. problem

Many scientific research institutions, enterprises and individuals around the world are developing alcohol-based liquid combustion gasifiers, but after more than 20 years, none of them can successfully solve these problems
