Abstract
The invention relates to an energy-saving furnace, which comprises a combustion chamber and a smoke exhaust port, and also comprises a smoke waste heat recycling pipeline, wherein the smoke waste heat recycling pipeline comprises an air pipe, a pre-heating pipe and a U-shaped bushing, one end of the U-shaped bushing is sleeved on a smoke exhaust pipe, the other end of the U-shaped bushing is sleeved on the pre-heating pipe, the bottom part of the U-shaped bushing is provided with a sealing end, the upper end of the pre-heating pipe is sealed, the lower end of the pre-heating pipe is fixedly connected to the bottom part of the sealing end, the side edge of the bottom part of the pre-heating pipe is provided with a gas outlet pipe which accesses to the combustion chamber, the air pipe passes through the bottom part of the sealing end to be plugged into the pre-heating pipe, and the sealing end is provided with a smoke outlet with the diameter being smaller than the aperture of the smoke exhaust pipe; and two ends of the U-shaped bushing are connected with the smoke exhaust pipe and the sealing end respectively through a flange structure. Air is supplied to the combustion chamber after being heated by the waste heat of the smoke, so the combustion efficiency is higher, the combustion efficiency of the furnace can be improved, the consumption can be reduced, and the cost is reduced.
Description
Technical field
The present invention 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.
Summary of the invention
The present invention 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 present invention, each is connected said U-shaped sleeve pipe two ends with the sealing termination with smoke exhaust pipe with flange arrangement.
The present invention 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 present invention is done further explain below.
Fig. 1 is a general structure sketch map of the present invention;
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 a specific embodiment of the present invention, among the figure; Respectively there are flange 4 structures at U-shaped sleeve pipe 3 two ends,, an end is connected on the smoke exhaust pipe 10 of combustion chamber 9 through flange 4; The other end covers on the economizer bank 2, and its bottom is equipped with a sealing termination 6, the sealing of economizer bank 2 upper ends through flange 4; The lower end sealing is fixed in sealing 6 bottoms, termination; Air hose 1 passes and is inserted in the economizer bank 2 from sealing 6 bottoms, termination, has an escape pipe 8 to pass sealing 6 access combustion chambers 9, termination in economizer bank 2 sides, and 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 present invention 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.
