Abstract
The utility model discloses a jet and absorption type gas burner which mainly comprises an inner interlayer sleeve, a gas nozzle fixed at one end of the interlayer sleeve, and an outer interlayer sleeve fixed on the outer surface of the inner interlayer sleeve, wherein, the gas nozzle is positioned inside the outer interlayer sleeve; and a ventilation door protruding outwards is arranged on the outer interlayer sleeve. The jet and absorption type gas burner is characterized in that the gas burner further comprises a baffle and a clamping block; one end of the baffle is movably connected with the upper end of the ventilation door; and the clamping block is fixed at the lower end of the ventilation door so that the other end of the baffle can only swing towards the inside of the ventilation door. The utility model not only absorbs air into a flame path in the working state of the gas burner, but also prevents combustion-supporting air from entering in non-working state.
Description
Technical field
The utility model relates to a kind of gas burner, specifically is meant a kind of emission-suction gas burner.
Background technology
At present, for the anode-baking furnace that improves domestic carbon product factory or the efficiency of combustion of cathode baking furnace, most anode-baking furnace or cathode baking furnace have all adopted the automatic control combustion system.In applied automatic control combustion system, all burners all are subjected to the control of computer or PLC, with quirk (furnace chamber) combustible gas injected of pulse mode to roaster, and come work according to predefined heating curve.The fuel gas that sprays in order to guarantee can fully burn, and also needs roaster is replenished certain combustion air.And present most burner all adopts air door open in usual to come the interior combustion-supporting air quantity of quirk (furnace chamber) to roaster to regulate.Because air door open in usual need be by the combustion case of technical staff according to reality, the aperture size of manual this air door open in usual of adjusting, therefore, the efficiency of combustion of whole roaster can be subjected to the restriction of factors such as at that time mood of technical staff, technical merit to a large extent; Simultaneously, because roaster mostly is the negative pressure method of operation, no matter and air door open in usual be burner in working order or off working state, all be in the state of unlatching all the time, therefore under the influence of the negative pressure in roaster, after quitting work, burner still have a large amount of cold airs to enter endlessly in the quirk (furnace chamber) of roaster by this air door open in usual.And this moment the cold air that enters under not combustion-supporting situation, the trend that interior the temperature of quirk (furnace chamber) is risen is affected, even lowers the temperature, thereby causes the intensification of burning of the more fuel gas of whole combustion system consumption, causes unnecessary waste.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of combustion-supporting air quantity that can not only enter quirk (furnace chamber) when the gas burner duty automatically is provided, can also when off working state, blocks the emission-suction gas burner that combustion air enters automatically.
The purpose of this utility model is achieved through the following technical solutions: a kind of emission-suction gas burner, mainly by the intraformational bed sleeve pipe, be fixed on the gas spray head of this intraformational bed sleeve pipe one end, and the outside sandwich sleeve pipe that is fixed on this intraformational bed bushing outer surface is formed, described gas spray head is positioned at the inside of outside sandwich sleeve pipe, and on the outside sandwich sleeve pipe, also be provided with a air door to outer lug, this emission-suction gas burner also includes baffle plate, and fixture block, one end of described baffle plate and the upper end of air door are movably connected, fixture block then is fixed on the lower end of air door, so that the other end of described baffle plate can only be to the swing of the inside of air door.
Resistance when entering gas spray head in order to reduce combustion gas, the air inlet of described gas spray head is made as taper shape.
The utility model compared with prior art has following advantage and beneficial effect:
(1) the utility model can Insulated wind door injects the defective of cold air to the quirk (furnace chamber) of roaster under off working state, can not only make programming rate quickening in the roaster, and, can also make the more old-fashioned burner of operating frequency of burner reduce by 20%～30% in the insulation period.
(2) the utility model can also be regulated the combustion-supporting air quantity that enters automatically according to the flow velocity of the combustion gas in the quirk that enters roaster (furnace chamber) when work, helps the abundant burning of combustion gas, thereby has also accelerated the speed that heats up.
Description of drawings
Fig. 1 is the integrally-built generalized section of the utility model;
Fig. 2 is the generalized section of gas spray head of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the utility model do, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the utility model mainly is made of intraformational bed sleeve pipe 1, gas spray head 2 and outside sandwich sleeve pipe 3.Intraformational bed sleeve pipe 1 is used to transmit fuel gas, and at an end of this intraformational bed sleeve pipe 1 also by the gas spray head 2 that has been threaded.
The outer surface of described intraformational bed sleeve pipe 1 airtight be fixedly connected with an outside sandwich sleeve pipe 3,2 of described gas spray head are by the fixing inside of outside sandwich sleeve pipe 3 of intraformational bed sleeve pipe 1.In order to make the internal-combustion of interlayer sleeve pipe 3 outside of combustible gas physical efficiency, also leave certain space between this intraformational bed sleeve pipe 1 and the outside sandwich sleeve pipe 3.Because fuel gas also needs a certain amount of combustion air when burning, entering of combustion air also is provided with an air door 4 to outer lug on this outside sandwich sleeve pipe 3 for convenience.Because roaster does not need entering of combustion air when the burner off working state, also control for better combustion-supporting air quantity to the quirk (furnace chamber) that enters roaster, also be connected with a baffle plate 5 in the upper end of described air door 4, and the shape of this baffle plate 5 and area are basic identical with the shape and the openings of sizes of set air door 4.
Come from by activity for the ease of the air intake of baffle plate 5 at air door 4, an end of this baffle plate 5 can fix on the upper end of air door 4 by hinges fixing, so that whole baffle plate 5 is suspended on the air inlet place of air door 4.When burner operation, owing to have fuel gas to flow through rapidly in the intraformational bed sleeve pipe 1, can produce certain negative pressure in the inside of roaster, make that baffle plate 5 can be the internal motion of air door 4 along the direction of negative pressure, thereby make on baffle plate 5 and the vertical plane and can produce an angle, the combustion air of combustor external is entered.When the flow velocity of the fuel gas in the intraformational bed sleeve pipe 1 is fast more, the negative pressure value of the inside of roaster is just big more, then baffle plate 5 is also just big more with the angle that vertical plane is produced, thereby make that the combustion-supporting air quantity in the quirk (furnace chamber) that enters roaster is just many more, thereby reach the effect that automatic control enters the combustion-supporting air quantity in the roaster.In order to prevent burner when duty becomes off working state, baffle plate 5 swings back and forth at the air inlet place of air door 4, also is fixed with a fixture block 6 in the lower end of air door 4 air inlets.Because this fixture block 6 has magnetic, therefore when burner during in off working state, baffle plate 5 can tightly be pull-in on this fixture block, so that the air of combustor external can not enter the quirk (furnace chamber) of roaster easily.
As shown in Figure 2, enter the resistance of burning during shower nozzle 2 in order to reduce combustible gas from intraformational bed sleeve pipe 1, the air inlet 7 of this burning shower nozzle is arranged to a taper shape.
As mentioned above, just can realize the utility model preferably.
