Abstract

An energy-saving air return furnace relates to a stove accessory, especially to an energy-saving stove accessory. The air return furnace provided in the utility model is composed of a panel, a furnace body, an ash collecting case and a smoke discharge pipe. The panel is located on the top of the furnace body while the ash collecting case is located on the bottom of the furnace body. A flue gas channel for flue gas to ascend is located between the external cylinder and the internal cylinder of the furnace body while a flue gas channel for flue gas to descend is located between the furnace body internal cylinder and the furnace core body. The top of the furnace core body is communicated with the flue gas channel for flue gas to descend. The flue gas channel for flue gas to descend and the flue gas channel for flue gas to ascend are communicated through a gravity settling chamber located on the bottom. The gravity settling chamber is located below the panel of the ash collecting case. The top of the flue gas channel for flue gas to ascend is communicated with a gravity settling chamber located below the panel through air vents. The gravity settling chamber is communicated with the smoke discharge pipe. The ash collecting case is provided with furnace core air inlets. The energy-saving air return furnace provided in the utility model is energy-saving, highly efficient and environment-friendly.

Description

The energy-conservation air return stove of collection intelligence

Technical field

The utility model relates to a kind of stove and accessory, particularly a kind of air return stove.

Background technology

Existing air return stove; Combustion chamber advances that the oxygen approach is single, fuel and airborne oxygen mix are insufficient, makes fully fuel of fuel, has wasted the valuable energy; Secondly the flue gas in the combustion process is only promptly discharged from smoke exhaust pipe through after the simple sedimentation; Still have a large amount of flue dust to fail to have been polluted air by abundant sedimentation in the flue gas, simultaneously the flue gas heat energy of together discharging is also wasted thereupon.

Summary of the invention

The purpose of the utility model is intended to overcome the deficiency of prior art, provides a kind of energy-saving and environmental protection and efficiency of combustion high energy-conservation air return stove.

The described energy-conservation air return stove of the utility model; Constitute by panel, body of heater, dust collecting box and smoke exhaust pipe; Panel is positioned at the top of body of heater, and dust collecting box is positioned at the bottom of body of heater, the exhaust gases passes that descends for flue gas between exhaust gases passes, inner core and the furnace core body that rises for flue gas between the urceolus of body of heater and the inner core; The exhaust gases passes UNICOM that the top of furnace core body and flue gas descend; The exhaust gases passes that exhaust gases passes that flue gas descends and flue gas rise is through the gravity settling chamber UNICOM of bottom, and this gravity settling chamber is positioned at dust collecting box panel below, and the exhaust gases passes top that flue gas rises is through the gravity settling chamber UNICOM on air vent and the panel; There are the combustion chamber air inlet in this gravity settling chamber and smoke exhaust pipe UNICOM on dust collecting box.

Described furnace core body is that the combustion chamber of furnace core body is up-small and down-big taper, between the outer wall of combustion chamber and the inwall of furnace core body the insulation filler is arranged on the cylindrical furnace core seat that is positioned at inboard wall of furnace body, and there is the combustion chamber blast cap in combustion chamber bottom central authorities, on the combustion chamber blast cap fresh air inlet are arranged.

On the described furnace core wall vent passages is arranged, the furnace core wall air inlet UNICOM on vent passages and the dust collecting box, vent passages is through fresh air inlet on it and the inner UNICOM of combustion chamber.There is pyrosphere in described panel central authorities, and pyrosphere can be at least more than one deck.Described dust collecting box is made up of dust collecting box panel, dust collecting box wallboard and ash door; Dust collecting box panel and dust collecting box wallboard are tightly connected and form the dust collecting box cavity; The ash door is positioned under inside cavity, the furnace core body, and combustion chamber air inlet and furnace core wall air inlet are positioned at ash door top.

Described combustion chamber air inlet place and furnace core wall air inlet place are provided with blower fan respectively.

Description of drawings

Fig. 1 has schematically shown the diagram according to the energy-conservation air return stove of the utility model.

The specific embodiment

Fig. 1 schematically shows according to the described energy-conservation air return stove 8 of the utility model, and body of heater 10 is the double-layer structure of urceolus 3, inner core 4, and furnace core body is cylindrical; The taper shape that 18 of combustion chambers are the outlet flue diameter less than air inlet 15 diameters, the space between furnace core outer wall 21,11 and the furnace core body inwall then adopt insulation filler 5; 6 fill, and keep the ignition temperature in the combustion chamber, and the below of combustion chamber is a combustion chamber blast cap 11; From combustion chamber air inlet 9; The air of 13 entering is disperseed the back to supply with the fuel 18 in the combustion chamber equably through the air vent on the combustion chamber blast cap 20 by the combustion chamber cap, makes fuel fully to combine with airborne oxygen, improves combustion rate.The passage 15 and furnace core wall air inlet 13 UNICOMs that are provided with on the furnace core wall; And through that be provided with on the furnace core wall and passage 20 passage UNICOM, promptly adopted multipath to advance the oxygen method airborne oxygen is sent in the combustion chamber from another face, make that the fuel in the combustion chamber can both be fully and oxygen mix in different angles; Thereby further reduced the oxygen supply dead angle; Improve the combustion rate of fuel, made fuel combustion more abundant, practiced thrift fuel.In order to have guaranteed that sufficient air gets into from air inlet, be provided with blower fan 14 respectively at combustion chamber air inlet place and furnace core wall air inlet place.When burning, the operation of flue gas through the gravity settling chamber 10 dual sedimentations under gravity settling chamber under the dust collecting box panel 7 16 and the panel 1, is deposited in the big dust particle in the flue gas in the case that gathers dust respectively preferably; Reduced and discharged the dustiness in the flue gas, experimental verification, the flue gas after upper and lower two gravity settling chamber sedimentations; Dustiness reduces significantly; Be merely prior art about 40%, thereby make discharging reach environmental protection, protected environment.A heat energy part that produces during fuel combustion is discharged with flue gas, the exhaust gases passes 2 of the utility model design, 17-1; 17-2,21,12; The discharging that makes flue gas is apart from lengthening, and the heat energy in the flue gas is fully conducted out by the inner core of body of heater, urceolus, dust collecting box panel 19, panel, supplies people's heating; Owing to increase heating surface area, make the panel of whole air return stove and body of heater warm and not boiling hot, realize the maximization of the utilization of resources.The described energy-conservation air return stove of the utility model, energy-conservation, efficient and environmental protection.

The described energy-conservation air return stove of the utility model is seen table 1 with the performance ratio of existing air return stove
