Abstract
The invention discloses a combustion furnace smoke exhausting method. An ejection tube smaller than a smoke exhaust tube is arranged in the smoke exhaust tube, smoke in the ejection tube is ejected out from an ejection tube outlet at a certain flow speed, and the ejection tube outlet is arranged on an outlet of the smoke exhaust tube or above the outlet of the smoke exhaust tube. The ejection tube smaller than the smoke exhaust tube is arranged in the smoke exhaust tube, the smoke in the ejection tube is ejected out from the ejection tube outlet at a certain flow speed, and the smoke to be exhausted in the smoke exhaust tube is ejected to be exhausted out of a smoke exhaust port by the energy generated from the ejected air in the ejection tube. The smoke in the smoke exhaust tube comes from a combustion chamber, a negative pressure hearth is formed in the combustion chamber, and the effect for ejecting the smoke out is realized. On the premise of guaranteeing smoke exhausting effect, impellers of a fan are free of contact with high-temperature smoke, and long service life, power saving and energy saving of the fan are realized.
Description
[technical field]
The present invention relates to a kind of smoke exhaust method of combustion furnace.
[background technology]
The stove of existing coal combustion or bavin or hay or stalk or combustion gas, the method of smoke evacuation generally is that a smoke exhaust fan is set in smoke discharging pipe, the cigarette that the stove of coal combustion or bavin or hay or stalk or combustion gas is produced blows out outdoor, the shortcoming of this method has: the impeller of blower fan directly contacts high-temperature flue gas, oil in the cigarette, vapour and travel fatigue are influential to the induced-draft fan service behaviour, the rotating speed of induced-draft fan is slowed down, even smoke electric wire or other components and parts of bad induced-draft fan, in case and the rotating speed of induced-draft fan slows down and maybe can not work, the cigarette that stove produces just can not blow out outdoor.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art part, provide that a kind of smoke discharging effect is good, the smoke exhaust method of the combustion furnace of the long service life of fume extractor, energy savings.
The object of the present invention is achieved like this:
A kind of smoke exhaust method of combustion furnace, it is characterized in that in smoke exhaust pipe, being provided with an induction tunnel, described induction tunnel is less than described smoke exhaust pipe, from induction tunnel outlet ejection, the induction tunnel outlet of described induction tunnel is in the exit position of smoke exhaust pipe or is in the upstream position of smoke exhaust pipe outlet air in the described induction tunnel with certain flow rate.
The smoke exhaust method of aforesaid a kind of combustion furnace, the cross-sectional area that it is characterized in that described smoke exhaust pipe be induction tunnel cross-sectional area 1-10 doubly.
The smoke exhaust method of aforesaid a kind of combustion furnace is characterized in that described smoke exhaust pipe and induction tunnel are pipe, the diameter of smoke exhaust pipe be induction tunnel diameter 1-10 doubly.
The present invention is provided with an induction tunnel in smoke exhaust pipe, induction tunnel is less than smoke exhaust pipe, and from induction tunnel outlet ejection, the energy that the inner flue gas that need discharge of smoke exhaust pipe relies on the injection of injection inner air tube to produce is discharged exhaust opening by injection to the air in the induction tunnel with certain flow rate.And the flue gas of smoke exhaust pipe inside is by the combustion chamber, thereby forms balanced draft furnace in the combustion chamber, reaches the effect that injection is discharged flue gas.Guaranteeing in the smoke discharging effect situation, because draught fan impeller no longer contacts high-temperature flue gas, realize that service life of fan is long, power saving, energy savings.
[description of drawings]
Fig. 1 is fundamental diagram of the present invention;
Fig. 2 is fundamental diagram of the present invention.
[specific embodiment]
A kind of smoke exhaust method of combustion furnace, in smoke exhaust pipe 1, be provided with an induction tunnel 2, the arrival end 10 of smoke exhaust pipe 1 communicates with the combustion chamber of combustion furnace, the flue gas that combustion chamber produces is discharged outdoor by smoke exhaust pipe, induction tunnel 2 is less than smoke exhaust pipe 1, from induction tunnel outlet 21 ejections, the exit position 11(that the induction tunnel outlet 21 of induction tunnel 2 is in smoke exhaust pipe is as shown in Figure 2 with certain flow rate for air in the induction tunnel 2) or be in the upstream position (as shown in Figure 1) of smoke exhaust pipe outlet.The energy that the flue gas of smoke exhaust pipe inside relies on the injection of injection inner air tube to produce is discharged from exhaust opening, and the flue gas of smoke exhaust pipe inside is by the combustion chamber, thereby forms balanced draft furnace in the combustion chamber, reaches the effect that injection is discharged flue gas.Guaranteeing in the smoke discharging effect situation, because draught fan impeller no longer contacts high-temperature flue gas, realize that service life of fan is long, power saving, energy savings.
Can be connected with at the entrance of induction tunnel 2 a blower fan (not shown), the air stream that blower fan produces sprays from induction tunnel outlet 21 after entering induction tunnel 2; Also can replace with compressed air the air-flow of blower fan generation, the two effect is consistent.
As shown in Figure 1, the distance that exports to induction tunnel outlet 21 of smoke exhaust pipe is L, and the diameter of induction tunnel 2 is D, and the diameter of smoke exhaust pipe is d, L=(1-15) * D, d=(1-10) * D.When the diameter of smoke exhaust pipe was 1 decimeter, the diameter of induction tunnel 2 was 1 centimetre, and induction tunnel outlet 21 is 1 centimetre to 15 centimetres to the distance L of the outlet of smoke exhaust pipe.
Claims (3)
1. the smoke exhaust method of a combustion furnace, it is characterized in that in smoke exhaust pipe (1), being provided with an induction tunnel (2), described induction tunnel (2) is less than described smoke exhaust pipe (1), from induction tunnel outlet (21) ejection, the induction tunnel outlet (21) of described induction tunnel (2) is in the exit position (11) of smoke exhaust pipe or is in the upstream position of smoke exhaust pipe outlet air in the described induction tunnel (2) with certain flow rate.
2. the smoke exhaust method of a kind of combustion furnace according to claim 1, the cross-sectional area that it is characterized in that described smoke exhaust pipe (1) be induction tunnel (2) cross-sectional area 1-10 doubly.
3. the smoke exhaust method of a kind of combustion furnace according to claim 1 is characterized in that described smoke exhaust pipe (1) and induction tunnel (2) are pipe, the diameter of smoke exhaust pipe (1) be induction tunnel (2) diameter 1-10 doubly.
