Technical field
The present invention relates to a kind of novel energy-saving range, specifically a kind of novel energy-saving range based on Stirling-electric hybrid.
Background technology
At present along with domestic gas-cooker technology constantly more, thermal efficiency of gas stove constantly promotes, but the efficiency of general gas kitchen range or undesirable, have even lower than State Standard Bureau in the GB16410-196 household gas range of issuing and implementation in 1997 defined 55%.Through constantly improving in the industry, a small amount of domestic energy-saving gas-fired range in recent years occurred can make the thermal efficiency be promoted to 70%, has improved to a great extent the serious situation of household gas range waste combustion gas.But the research for commercial gas-fired stove (gas-cooker that business, group are used) improves stagnation always, the thermal efficiency of commercial kitchen range surpasses 20% situation seldom, the GB regulation, the thermal efficiency of commercial gas-fired stove is 20%, and in fact practical application only has 15% left and right, that is to say, the energy of the overwhelming majority (more than 80%) runs off in vain.According to the national authority department statistics, there are 1,000 ten thousand restaurants, large, medium and small hotel in the whole nation, and according to statistics, will consume combustion gas every year, and diesel oil is amounted to regular fuel 2000-3000 ten thousand tons, is equivalent to a Daqing oil field! The research and development of energy saving gas cooker are significant for China's energy conservation.
The reason of commercial gas-fired stove slower development is, the commercial gas-fired stove requirement efficiency of heating surface is high, cost is low, and the interim energy-saving efficiency promoted of new gas technology is not high, can reduce the efficiency of heating surface simultaneously, the reduction of the efficiency of heating surface means that cooking efficiency descends, and then affecting the economy in restaurant, the exploitation of novel commercial energy-saving stove can not get user's support energetically.
On market, the commercial gas-fired stove main body is Draught gas burner and gas-combusting stove for Chinese meal.The Draught gas burner compact conformation, combustion intensity is large, and cooking efficiency is high, but needs to consume electric energy; The gas-combusting stove for Chinese meal flameholding, easy to use, but combustion intensity is little, and cooking efficiency is low.Most of business unit are for improving cooking efficiency, and heating intensity, can select Draught gas burner.Draught gas burner combustion gas utilization rate is in about 10m3/h, air blast power consumption 200W, and general restaurant is 10 hours every days the kitchen working time, 6 hours gas-cooker working times single-stove type gas-cooker, year air consumption 2.19 * 10
4m
3, power consumption 438 degree, blower motor life-span 2-3.In addition, air blowing gas range, blast cold wind by the below air inlet, when improving efficiency of combustion, also makes the more heat of flame heat the air newly blasted, and causes the meaningless consumption of heat.

The specific embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the invention will be further described.
In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, a kind of novel energy-saving range based on Stirling-electric hybrid, by stove, V-type Stirling mechanism, air blast (11), formed, V-type Stirling-electric hybrid mechanism comprises hot cylinder (6), cooling cylinder (7), heater (5), cooler and regenerator (2), it is characterized in that: heater (5) is the high-temperature resistant tube of shape on screw, be placed in burner (4) position of stove, can surround flame, absorb the waste heat that flame distributes to surrounding; Cooler, by being located at a side water tank (1) of stove, forms water-cooled part (9), and the air channel (3) of air blast (11), through the passage (12) of water-cooled part (9), forms air-cooled part (10).The hot cylinder (6) of Stirling-electric hybrid mechanism and cooling cylinder (7) drive by connecting rod the runner of being located on stove and rotate, and by the direct blower of conveyer belt (8) transmission (11).
Water-cooled part (9) is provided with the water-cooled fin with regenerator (2) contact position; Air-cooled part (10) is provided with air cooling fin with regenerator (2) contact position.
The gas outlet, air channel (3) of air blast (11) is connected with the burning bucket bottom of stove.
Cooler water-cooled part (9) is by water tank (1), the culinary art water in heating water tank (1).
In the second embodiment shown in Fig. 1, Fig. 2, Fig. 4, the type of cooling of cooler comprises two kinds of air-cooled and water-cooleds.Cooling effect the best of running water, but cost is high, and for strengthening cooling effect, the present invention adopts secondary cooling.The first type of cooling is air-cooled, the wind that the air blast (11) that Stirling engine drives the blows out fin that (3) blow cooler through air channel is realized air-cooled, and the heat that cooler distributes simultaneously can reduce to the wind preheating of air blast (11) waste of fuel again.The second type of cooling is water-cooled, and this part cooling tube is not established fin, directly by water tank (1), is surrounded and is realized water-cooled.Simultaneously water tank (1) arranges intake and water compensating valve, and the heat heating that device distributes that is cooled of the water in water tank (1), can be used for culinary art, so also realized the saving of fuel.The cold rear water-cooled of advanced sector-style, guaranteed the cooling requirement of cooler.
Regenerator (2) adopts the woven wire of minor diameter to make regenerator (2) filler.The present invention adopts 120 purpose stainless steel cloths to be sintered together, as regenerator (2) filler.
The course of work of the present invention: igniting, flame adds hot heater (5), heater (5) and the interior gas expansion of hot cylinder (6), Stirling-electric hybrid enters the heating stroke, hot cylinder (6) piston draws outward, and cooling cylinder (7) piston advances, and Working medium gas flows to expansion space (high-temperature space) from compression stroke (low temperature space), flow to hot cylinder (6) end, engine interior pressure rise from cooling cylinder (7) end.Expansion stroke is pressure outer drawing all that two pistons are subject to working gas, and at this moment engine has just obtained a driving force.Enter cooling stroke after expansion stroke: utilize the energy that flying wheel is laid in that runner is rotated, at this moment hot cylinder (6) piston advances, and cooling cylinder (7) piston draws outward.Working gas just flows into compression stroke from expansion space, from hot cylinder (6) end, to cooling cylinder (7) end, flow, cooling through regenerator (2), cooler water-cooled part (9) and the air-cooled part of cooler (10) in flow process, the gas working medium temperature reduces, and the Stirling-electric hybrid internal pressure decreases.Then enter compression travel: owing to being subject to air pressure and the plunger backer surface pressure is poor, two pistons advance simultaneously, and gas volume reduces.Compression travel makes Stirling-electric hybrid get back to initial position, and then Stirling-electric hybrid enters the heating stroke again, so circulation, constantly outputting power.The power of exporting passes to air blast (11) by runner and belt, and the cold wind that air blast (11) blows out is constantly given the Working medium gas cooling of cooling cylinder (7) end by the air-cooled part of cooler (10), while cold wind heating wind, and it is combustion-supporting to send into burner (4).The continuous cooling water-cooled fin of water in water tank (1), the heated water kitchen water that can be used for eating.
Between regenerator (2) and water tank (1) and heating tube, use flange to be connected, heating tube also is connected with flange with hot cylinder (6).Cooling tube is used flange to be connected with cooling cylinder (7), and connecting portion is all used the high temperature high-pressure resistant material sealing.Hot cylinder (6), cooling cylinder (7) are 90 ° of angles and are fixed on square shelf, and runner is by 2 belt transmission, by transmission of power to air blast (11).
