Description

A kind of fast, catalysis do not have the environment-friendly type of pressure alcohol radical liquid fuel kitchen range

The utility model relate to a kind of fast, catalysis do not have the environment-friendly type of pressure alcohol radical liquid fuel kitchen range, belongs to the liquid fuel cooking range of home furnace class, is specially adapted to the large-scale cooking kitchen range of catering trades such as hotel, restaurant, collectiveity canteen, is applicable to that single family uses yet.

Existing liquid fuel cooking range, all being to follow preheating,---mode of---overheated---burning of gasification is carried out, its shortcoming is, preheating time is long, incomplete combustion, knot charcoal or obstruction, produce irritative gas, according to existing disclosed utility model patent, though improvement is arranged, but it is by a plurality of vaporizers, a plurality of air storage chambers and fuel tank are formed, between each vaporizer, between the air storage chamber, be communicated with each other and between the fuel tank, in each vaporizer, be installed with a heat conduction breather pipe and the heat conduction oil-feed playpipe more than, complex structure, connecting pipe is many, and want some combustion gas separately to be used for the heating and gasifying chamber, reduced the cooking stove firepower, use also dislike long its preheating time through practice, need approximately could start in about 3 minutes, and this be a kind of combustion gas of controlling after the gasification control combustion process the pressure stove and accessory arranged, pressure is also arranged in the fuel tank, must tightly seal, there is potential safety hazard, can not adds fuel during burning, the large-scale cooking stove of present collectiveity canteen etc., all be to adopt coal gas, liquefied petroleum gas, even have and much be to use diesel oil, preceding two kinds of expense costlinesses, the diesel oil cooking stove is the expense costliness not only, and easily tie charcoal, incomplete combustion, it is big to produce the pernicious gas noise, contaminated environment.

The purpose of this utility model is: provide a kind of simple in structure, member is few, preheating time is short, flame temperature is high, control combustion process with the control liquid fuel, burning with the catalyst fuel gas, improve flame temperature, free from environmental pollution, do not have pressure, safe and reliable fast, catalysis do not have the environment-friendly type of pressure alcohol radical liquid fuel kitchen range.

This quick, catalysis does not have the environment-friendly type of pressure alcohol radical liquid fuel kitchen range,---the mode of gasification---catalysis---burning that its design is: adopt preheating, the control alcohol radical liquid fuel is controlled combustion process design, the liquid fuel of fuel tank is through electronic ignitor switch, earlier liquid is sent into the preheating dish, constantly send into the vaporizer that is connected as a single entity with air storage chamber then, ignition is lighted the fuel in the preheating dish simultaneously, liquid fuel in the vaporizer is carried out preheating, gasification, combustion gas enters air storage chamber by vaporizer, and uniform aperture ejection burning from its top cover, can start burning ten seconds, flame also directly heats the heating collar and the heat conducting bar in its aperture sky simultaneously, heat conducting bar transfers heat in the vaporizer, ground preheating and gasification keep, combustion gas sprays continuously, so sustainable carrying out of burning, be exposed to outer heating collar, heat conducting bar and vaporizer, the surface that the air storage chamber top cover contacts with burning, be coated with the metal oxide catalyst of one deck catalytic combustion, its fierce burning of catalysis, improve flame temperature, multi-joint large-scale cooking stove for collective's catering trade, one cover waste gas recycle device is set, it is with the partially enclosed hearth-type pot supporter that becomes of pot supporter, make waste gas enter flue, after condenser cooling, enter water tank and utilize CO in its waste gas ₂Make chemical products with chemical agent effect in the water, as washing agent etc.
