Description

Liquid fuel energy-saving and emission-reduction evaporation burner

Technical field

The invention belongs to Domestic stove, particularly a kind of vaporization combustion stove and accessory of liquid fuel.

Background technology

Traditional liquid fuel range is not provided with vapourizing unit, to making incomplete combustion, not only wasted energy but also contaminated environment, and the carbon deposit phenomenon is serious, uses to be out of order often.I applied for and obtained the Chinese utility model patent of a plurality of liquid fuel ranges once; For example: on November 5th, 2003, Granted publication had a name to be called the utility model patent CN2585079Y of " liquid fuel vaporizer ", it is characterized in that being provided with ignitron kept burning day and night and spiral economizer bank, and it can be vaporized the liquid fuel preheating; It is improvement to the traditional liquid fuel stove; But its complex structure, cost of manufacture is high: and also the preheating vaporization is slowly, and the firepower amplitude of accommodation is also little; How carbon deposit in the fuel channel can't discharge easy break-down again simultaneously; On March 14th, 2007, Granted publication had a name to be called the utility model patent CN2878969Y of " liquid fuel evaporation burner "; It is characterized in that having burn chew, flexible coupling, nozzle and catch tray; It improves the former, but still does not have thoroughly to solve the difficult problem of fuel carbon deposit blocking channel; On the market, a kind of liquid fuel evaporation burner of structure similar of and product of the present invention is arranged, it is mainly assembled by fuel-feed pipe, catch tray, fuel arm, U type generating tube, cross generating tube, nozzle and charging control valve etc.; Charging control valve wherein is connected on the fuel-feed pipe; Nozzle is arranged on the minimum place of bending of U type generating tube, and the major defect that it exists during actual the use is: at the igniting initial stage, liquid fuel can splash into the catch tray from nozzle in a large number; Fuel preheating, vaporization rate are slow; Spray insufficient and cause incomplete combustion, not only firepower is regulated slowly, dumb, and the dry sound that burns is big.

Summary of the invention

To the defective that prior art exists, intend above-mentioned liquid fuel evaporation burner is on the market carried out architecture advances, manufacture and design a kind of liquid fuel energy-saving and emission-reduction evaporation burner; The initial stage dropping liquid amount that makes it to light a fire is little; Fuel preheating, vaporization rate are fast, spraying fully, burning is fully; But firepower regulated at will, and the no dry sound of burning.

The technical scheme that the present invention taked is following.

A kind of liquid fuel energy-saving and emission-reduction evaporation burner; Comprise fuel-feed pipe, catch tray, fuel arm, U type generating tube, nozzle, support ring, fire-collected ring and cross generating tube; Fuel arm symmetry is connected on the upright fuel-feed pipe; The two ends of the other end of two fuel arms and U type generating tube are communicated with the cross generating tube, and catch tray is fixed on the upright fuel-feed pipe, and support ring is fixed on upright fuel arm and the U type generating tube; Fire-collected ring is shelved on the support ring, it is characterized in that:

1) this evaporation burner also has pin type gas control valve and combustion gas silencer cover;

2) offer air admission hole on the sidewall of pin type gas control valve; The upright position that pin type gas control valve level is passed U type generating tube is right-angled intersection and is welded as a whole; And be communicated with U type generating tube through air admission hole, pin type gas control valve end is communicated with nozzle;

3) combustion gas silencer cover bottom offers fresh air inlet, and the upper surface is uniformly distributed with and offers fuel gas hole, and the center of lower surface offers installing hole, and the combustion gas silencer cover is fixed on the nozzle through installing hole.

Liquid fuel energy-saving and emission-reduction evaporation burner of the present invention can use liquid fuels such as methyl alcohol, ethanol or lighter hydrocarbons, and activation pin type gas control valve can be lighted a fire to the preheating of burner interior conduit; The preheating initial stage can light the liquid fuel that splashes on a small quantity in the catch tray; Auxiliary preheating, and then pipeline is heated up rapidly to the burner interior conduit, the air pressure in the U type generating tube increases along with the boil-off rate of fuel and is able to increase sharply; Thereby make through the injected fuel spray of pin type gas control valve and nozzle ejection abundant; And drive the fresh air inlet entering of air from combustion gas silencer cover bottom, fully mix in the combustion gas silencer cover with vaporized fuel, thereby make combustion gas can realize completing combustion; The not only available pin type of combusting firepower gas control valve regulated at will, and can also realize the no dry sound of burning.It is energy savings but also reduce pollutant emission not only, and easy-to-operate has overcome the defective that prior art products exists fully, is particularly suitable in catering industry and family kitchen, promoting the use of.
