Abstract
An energy-saving furnace comprises a combustion chamber, a smoke discharging port and a smoke waste heat recycling pipeline. The smoke waste heat recycling pipeline comprises an air pipe, a preheating pipe and a U-shaped sleeve pipe. One end of the U-shaped sleeve pipe is covered on a smoke discharging pipe, the other end of the U-shaped sleeve pipe is covered on the preheating pipe, and a sealing end head is installed at the bottom of the U-shaped sleeve pipe. The upper end of the preheating pipe is sealed, the lower end of the preheating pipe is fixedly connected to the bottom of the sealing end head in sealing mode, and an air outlet pipe is disposed on the lateral side of the bottom of the preheating pipe and connected to the inside of the combustion chamber. The air pipe penetrates through the bottom of the sealing end head to be inserted in the preheating pipe, the sealing end head is provided with a smoke outlet, and the diameter of the smoke outlet is smaller than that of the smoke discharging pipe. Both ends of the U-shaped sleeve pipe are respectively connected to the smoke discharging pipe and the sealing end head through flange structures. The energy-saving furnace utilizes smoke waste heat to heat the air which is supplied to the combustion chamber, thereby enabling combustion efficiency to be high, improving combustion efficiency of the combustion furnace, reducing consumption and lowering cost.
Description
Technical field
The utility model relates to a kind of heating furnace, be specifically related to a kind of can be with the energy-conservation stove of flue gas waste heat recovery.
Background technology
In machining, in technical process such as galvanizing, all can use gas furnace and come to carry out to machined part preheating; Usually gas furnace has only and simply advances Gas Pipe, air hose and smoke evacuation tracheae; Combustion gas produces heat energy with air mixing after-combustion heats, yet the flue gas that discharge the burning back all has the above high temperature of 200 degree usually, and this has just caused a large amount of heat-energy losses; Cause bigger waste virtually, improved the production cost of gas consumption and enterprise.
The utility model content
The utility model provides a kind of energy-conservation stove, can make the waste heat of flue gas obtain utilizing, and has improved the combustion gas utilization rate, has reduced cost.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of energy-conservation stove comprises combustion chamber, exhaust opening, also includes a flue gas waste heat recovery pipeline; Said flue gas waste heat recovery pipeline comprises air hose, economizer bank and U-shaped sleeve pipe, and an end shield of said U-shaped sleeve pipe is on smoke exhaust pipe, and the other end covers on the economizer bank; Its bottom is equipped with a sealing termination; The sealing of economizer bank upper end, the lower end sealing is fixed in the sealing head bottom part, has an escape pipe to insert the combustion chamber in sides; Said air hose passes from the sealing head bottom part and is inserted in the economizer bank, and the sealing termination is provided with an exhanst gas outlet littler than smoke exhaust pipe bore.
As a preferred version of the utility model, each is connected said U-shaped sleeve pipe two ends with the sealing termination with smoke exhaust pipe with flange arrangement.
The utility model is through adopting a U-shaped sleeve pipe and economizer bank, supplies with the combustion chamber after the air heat that the waste heat that utilizes flue gas feeds air hose through economizer bank, makes efficiency of combustion higher, improved the burner efficiency of combustion, reduced consumption, reduced cost.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model general structure sketch map;
Among the figure:
1, air hose; 2, economizer bank; 3, U-shaped sleeve pipe; 4, flange; 5, exhanst gas outlet; 6, sealing termination; 7, inlet of cold air; 8, escape pipe; 9, combustion chamber; 10, smoke exhaust pipe.
The specific embodiment
As shown in Figure 1, provided the described specific embodiment of the utility model, among the figure; Respectively there are flange 4 structures at U-shaped sleeve pipe 3 two ends, and an end is connected on through flange 4 on the smoke exhaust pipe 10 of combustion chamber 9, and the other end covers on the economizer bank 2; Its bottom is equipped with a sealing termination 6 through flange 4; The sealing of economizer bank 2 upper ends, the lower end sealing is fixed in sealing 6 bottoms, termination, and air hose 1 passes from sealing 6 bottoms, termination and is inserted in the economizer bank 2; Have an escape pipe 8 to pass sealing 6 access combustion chambers 9, termination in economizer bank 2 sides, sealing termination 6 is provided with the little exhanst gas outlet 5 of a relative aperture smoke exhaust pipe 10.
The flue gas of discharging when combustion chamber 9 gets into U-shaped sleeve pipe 3 along the direction of arrow; Its waste heat is with economizer bank 2 heating; The air that gets into economizer bank 2 bottoms through air hose 1 is by economizer bank 2 heating; Through the escape pipe 8 entering combustion chambers of economizer bank 2 bottoms,, improved the efficiency of combustion of combustion gas then through behind the air and combustion gas mixing of preheating.
The utility model is simple in structure, is easy to realize, through adopting a U-shaped sleeve pipe 3 and economizer bank 2; Supply with burner after the air heat that the waste heat that utilizes flue gas feeds air hose through economizer bank; Make efficiency of combustion higher, improved the burner utilization rate, reduced consumption; Reduce cost, improved the performance of enterprises.
