Description

Gas kitchen ranges efficient energy-saving device

Technical field

The present invention relates to gas kitchen ranges, specifically gas kitchen ranges efficient energy-saving device.

Background technology

Gas kitchen ranges is the little article of family's indispensability outwardly, but the energy utilization rate of gas kitchen ranges is then related to the large industry of the energy of country.Under the historical background of energy crisis, low energy consumption and economize energy are the indexs that must meet concerning gas kitchen ranges.

The adequacy of fuel gas buring, effective utilization of firepower are two aspects improving energy utilization rate.Gas kitchen ranges measure in this respect comprises and contacts with composition of air and promote to burn completely, and by flame focus utilization to avoid heat loss.

CN102777941A discloses a kind of high-efficiency gas cooking range, comprise kitchen range main body, boiler face and the burner be arranged in kitchen range main body and corresponding burner and be arranged on cooker racks on boiler face, it is also provided with energy gathering cap between burner and cooker racks, described energy gathering cap be to be assemblied in bottom cooker racks and outside burner between ring-type cover body; Energy gathering cap is that heat preserving and insulating material is made.The advantage of such design is that the heat loss of fuel gas buring can drop to minimum by energy gathering cap, greatly improves the thermal efficiency.

CN2114779 discloses a kind of gas burning range, adopts porous honeycomb catalytic sheet, and when combustion gas is by the burning of porous catalytic sheet, owing to disperseing fully, burning completely, both can be saved combustion gas, and can reduce again the pollution of waste gas to air in kitchen.

But it is too complicated that these measures have, and some effects are unsatisfactory.

Summary of the invention

In order to solve the problem, by the simple method of one, both can really promote that combustion gas was burnt more fully, can thermal loss be reduced again, the invention provides a kind of gas kitchen ranges efficient energy-saving device.

Gas kitchen ranges efficient energy-saving device of the present invention, comprises combustion catalysis plate, the windproof tube that can surround whole flame, leg; Combustion catalysis plate is the porous plate of load combustion catalyst, and is placed in windproof tube upper inside wall; Leg is positioned at windproof tube bottom.

In the present invention, the combustion catalyst of combustion catalysis plate load is attached to surface and the hole wall of combustion catalysis plate by the mode of attachment.The mode of attachment has multiple, comprises physics stickup, high temperature sintering etc.No matter adopt any mode, all need to ensure adhesion-tight and high temperature resistant flame combustion.

Combustion catalyst has a lot, and the combustion catalyst that the present invention selects is the complex rare-earth oxidate containing valuable metal of rare earth based perovskite or hexa-aluminate.

The aperture of described porous plate is 0.05 ~ 2mm, span 0.3 ~ 1.5mm.Because the combustion catalysis plate in apparatus of the present invention plays a role to burned flame, instead of at burning root, the pressure of flame is very little, much smaller than the gaseous-pressure of burning root, if aperture is too little be unfavorable for that flame passes through.When contrary aperture is too large, flame is very soon through the hole on porous plate, and flame and combustion catalyst time of contact and contact area all not, are unfavorable for catalytic combustion and sufficient combustion.Suitable aperture could not only can make flame smoothly by but also ensure flame fully to contact with combustion catalyst and guarantee to burn complete.Span impact be the quantity in hole, so also must select suitable.

The agglomerated material that the base material of porous plate is pottery containing micropore or slightly makes through the surface that high temperature sintering is crossed.Here it should be noted that " hole " of " micropore " in " pottery containing micropore " is diverse hole with " hole " of " porous " of porous plate." hole " of " micropore " in " pottery containing micropore " is irregular, and the factors such as the raw material of being made pottery by preparation and sintering temperature are formed, and its pore diameter range is 1nm ~ 100 μm.The very suitable adsorption catalyst of these micropores.The face of slightly making a list of the same agglomerated material slightly made through the surface that high temperature sintering is crossed is also favourable to the attachment of catalyst.The pottery that the present invention selects or agglomerated material, all through high temperature sintering mistake, are therefore suitable for use as combustion catalysis plate.

As preferably, windproof tube inwall is provided with step or projection, for laying combustion catalysis plate.Such scheme is conveniently laid, and combustion catalysis plate is not fixed, but is placed on it actively, is beneficial to and changes and take off clean.

For the ease of observing flame, also in order to supplemental oxygen better, windproof tube barrel arranges multiple through hole.

Catalytic combustion is under the effect of catalyst, and fuel and air carry out heterogeneous complete oxidation at catalyst surface.Compared with traditional flame combustion, catalytic combustion has: (1) initiation temperature is low, flameholding; (2) efficiency of combustion is high; (3) pollutant (NOx, imperfect combustion product C O etc.) emission level is low; According to interrelated data introduction, utilize catalytic combustion technology can improve the thermal efficiency 64%, efficiency of combustion can reach 99.5%, and energy-saving effect reaches more than 15%.Utilize catalytic combustion technology to change combustion system, improve efficiency of combustion, reducing the formation of NOx and imperfect combustion product, is the future thrust of combustion technology.

The rare earth based perovskite that the present invention uses, hexa-aluminate complex rare-earth oxidate containing valuable metal are the catalysis materials at the comparatively ripe terres rares catalytic combustion of natural gas high temperature catalytic combustion application aspect, be the RE treatment steel utilizing group of molecules packing technique to prepare, there is low price, raw material is easy to get, resistance to elevated temperatures good, at high temperature there is the advantages such as good stability.

Gas kitchen ranges efficient energy-saving device of the present invention, windproof tube windproofly can dispel flame, and porous plate can make firepower be uniformly distributed, thus greatly reduces thermal loss; Catalyst adhesion-tight, catalyst and the flame contact time long, contact area is large, and Catalytic Combustion Effect is good, makes burning completely, discharges maximum heats, reduce the formation of NOx and imperfect combustion product, have energy-efficient, advantages of environment protection.

Apparatus structure of the present invention is simple, effective, easy to use.Only need the cooker racks of gas kitchen ranges to take away during use, this device is placed on the liquid-bearing pan of gas kitchen ranges, then puts cooker racks.
