Abstract
Disclosed is an environment-friendly and energy-saving support device for burning appliances, which comprises a cooker supporting block, an energy-saving plate, a corrugated boss, a heat insulation layer, a shell and a holder. The cooker supporting block is connected with the energy-saving plate, and comprises a plane and a slope for supporting a pan or a sharp-bottomed boiler. The energy-saving plate is a curved or linear annular structure and connected with the shell to form an annular space chamber. The space chamber as the heat insulation layer can be filled with the large thermal resistance materials or the gases with small thermal conductivity or vacuumized. The holder is connected with the shell for supporting the whole plate. The device changes the traditional opening combustion into the semi-closed combustion, thus improving the thermal efficiency when in combustion. The semi-closed structure allows the flue gas to stay over a long time in the high-temperature zone and through the sufficient combustion the CO content in the flue gas is reduced. The device increases the environmental applicability of the gas cooker, preferably selecting the large-power range, and still radiates the residual heat when the gas cooker is cut off. The device adopts simple structure, is convenient for processing and achieves the effects of protecting the environment and saving energy.
Description
Affiliated technical field
The utility model relates to the energy-conserving and environment-protective bracing or strutting arrangement on a kind of burning appliance, and particularly grate is supported in energy-conserving and environment-protective on the gas kitchen ranges.
Background technology
Gas-cooker commonly used is general to be divided embedded and desk-top two kinds, and combustion system generally divides atmospheric burning type and porous infra-red radiation to burn two kinds.No matter be embedded or desk-top gas-cooker,, all there is the heat-energy losses problem in varying degrees no matter be atmospheric burning type or infra-red radiation burning.Especially the burning of the open type between gas-cooker and the cooker makes the heat loss phenomenon fairly obvious.This is because heat that fuel gas buring discharged in heating cooker, also discharges a large amount of heat with thermal convection current, heat conduction, thermal-radiating mode to the external world around cooker, especially when flame during by air agitation heat-energy losses even more serious.With center ring " flammule " burning the time, a burst of gentle breeze can flame blow-off.The open type burning makes flue gas short in the combustion zone time of staying owing to there is more serious heat loss through convection, and combustion zone temperature reduces, and the CO content in smoke that is produced by imperfect combustion increases, and efficient reduces.
At present, stipulate among the standard GB 16410-2007 that the desk-top kitchen range thermal efficiency 〉=55% embeds kitchen range efficient 〉=50%, CO concentration≤500ppm in the dry flue gas.Yet along with the increase of service life, the thermal efficiency that cooker is burnt by influence of various factors also descends to some extent, and the thermal efficiency reduces discharging such as the unburnt gas that also can cause CO increase, has so both wasted energy, again contaminated environment and the health that influences the user.
Summary of the invention
Low in order to overcome the heat transfer efficiency that burns in the existing combustion gas tool, burning produces CO in the flue gas, the high deficiency of NOx content, the utility model provides a kind of support grate of energy-saving and environmental protection, this grate makes traditional open type burning become semi-enclosed burning, reduce fuel gas buring and produce convection current, radiation, the conductive heat loss of heat, improved the thermal efficiency to the external world.After tested, use this Energy-saving stove rack to improve 10 ~ 15% than the thermal efficiency that uses common grate.Semi-enclosed burning has prolonged the time of staying of flue gas at combustion zone, forms the backflow of flue gas in the high-temperature region, makes combustion zone temperature keep very high, has increased the speed of combustion reaction, makes burning more abundant, has greatly reduced the CO content in the combustion product gases.After tested, use CO content in the gas-cooker flue gas of this Energy-saving stove rack far below the index of the 500ppm of national standard.Simultaneously, owing to adopt semi-enclosed burning to make gas-cooker have bigger environmental suitability, can resist the interference that bigger ambient windstream flows.In use internal heat " flammule " when burning, can not only improve the thermal efficiency of burning, but also can prevent that air-flow from blowing out little fire.Like this, when kitchen range and smoke exhaust ventilator coupling, can select high-power smoke exhaust ventilator, or reduce the setting height(from bottom) of smoke exhaust ventilator, it is outdoor that kitchen fume is discharged to greatest extent, greatly improved the indoor environment in kitchen.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of environmental protection and energy saving bracing or strutting arrangement that is used on the burning appliance comprises: energy-conservation disk body, thermal insulation layer, shell, corrugated boss, pot back-up block, bearing.Its architectural feature is: the curved face type disk body of ring-type and shell are formed " space chamber " of a sealing, fill big thermal resistance material (as pearlife etc.) in " space chamber " or be pumped into certain vacuum degree or the big gas of falling heat-transfer coefficient, " space chamber " limited gas flow and reduced convection current, conductive heat loss, and the heat that burning is discharged is concentrated and is radiated the bottom of a pan.Corrugated boss on the disk body can change the gas flow state, and the pot back-up block is connected with disk body can support pan or tip bottom pot, and bearing is connected with shell, supports whole disk body.Whole support grate is placed on the burner of kitchen range.
The shape of above-mentioned curved face type disk body can be curved face type or linear, and can add undulatory boss, and has counter flange.
Above-mentioned pot back-up block is at least 3, can evenly distribute, also can non-uniform Distribution.
Above-mentioned thermal insulation layer can be filled big thermal resistance material, or is evacuated or gas that the falling heat-transfer coefficient is little.
Above-mentioned bearing can be columniform, also can be circular platform type, also can have the shape of a saddle of radian, can punching on the bearing with the auxiliary air of aftercombustion.
The beneficial effects of the utility model are: the open type burning become semi-enclosed burning, improve the thermal efficiency of fuel gas buring, make flue gas long in the combustion zone time of staying of high temperature, and the chemical reaction rate height, fuel gas buring is abundant, and the C0 content in the flue gas is low.After tested, use this Energy-saving stove rack to improve 10～15% than the thermal efficiency that uses common grate, the CO content in the gas-cooker flue gas is far below the 500ppm of national standard.Semi-enclosed structure reaches windproof purpose, has improved the environmental suitability of gas kitchen ranges, when middle internal heat " flammule " is burnt, uses this energy-saving and environmental protection grate not only can improve combustion thermal efficiency, and flame is difficult for being gone out by wind, and it is safer to burn.After kitchen range fire extinguishings, this Energy-saving stove rack holding heat radiation on members such as distributor, disk body to pan, further utilizes waste heat by insulation, radiation.When kitchen range and the supporting use of smoke exhaust ventilator, can match powerful smoke exhaust ventilator or reduce the setting height(from bottom) of smoke exhaust ventilator, further purify the kitchen indoor environment, reach environmental protection, energy-conservation effect, simple in structure, processing, easily manufactured.
