Abstract
The invention discloses a fuel gas heating energy-saving device in a heat treatment furnace. The device comprises a nozzle and a natural gas pipe and an air pipe which are interconnected with the nozzle, wherein the natural gas pipe is provided with a first fuel gas electromagnetic valve, an air-fuel proportional valve, a hand-operated valve and a second fuel gas electromagnetic valve in turn; the other end of the air pipe is provided with a combustion-supporting fan and a variable frequency motor; the air pipe is provided with an air butterfly valve; and the air pipe is connected with the air-fuel proportional valve through a pressure guide pipe. The device has the advantages of high adjustment precision by adopting the variable frequency combustion-supporting fan to adjust the air quantity, low energy consumption and capability of effectively saving the energy.
Description
Technical field
The present invention relates to a kind of heat-treatment furnace, relate in particular to the fuel gas heating energy-saving device in a kind of heat-treatment furnace.
Background technology
Burner in the existing heat-treatment furnace, comprise: burner, with interconnective natural gas tube of burner and air hose, on natural gas tube, be disposed with first gas electromagnetic valve, hand-operated valve and second gas electromagnetic valve, the other end of air hose is provided with combustion fan and servomotor, and air hose is provided with air butterfly valve.Burner in the existing heat-treatment furnace, in use, instability, degree of regulation is not high, and energy consumption is bigger.
Summary of the invention
Technical problem to be solved by this invention provides the fuel gas heating energy-saving device in the low heat-treatment furnace of a kind of energy consumption.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: the fuel gas heating energy-saving device in the heat-treatment furnace, comprise: burner, with interconnective natural gas tube of burner and air hose, on described natural gas tube, be disposed with first gas electromagnetic valve, air-fuel ratio valve, hand-operated valve and second gas electromagnetic valve, the other end of air hose is provided with combustion fan and variable-frequency motor, and air hose is provided with air butterfly valve, and air hose is connected with the air-fuel ratio valve by connecting pipe.
Advantage of the present invention is: the fuel gas heating energy-saving device in the above-mentioned heat-treatment furnace, and adopt the frequency conversion combustion fan to adjust the size of air quantity, the degree of regulation height, energy consumption is low, effectively energy savings.
Description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the fuel gas heating energy-saving device in the heat-treatment furnace of the present invention.
Among the figure: 1, burner, 2, natural gas tube, 3, air hose, 4, first gas electromagnetic valve, 5, the air-fuel ratio valve, 6, hand-operated valve, 7, second gas electromagnetic valve, 8, combustion fan, 9, air butterfly valve, 10, connecting pipe.
The specific embodiment
As shown in Figure 1, fuel gas heating energy-saving device in the heat-treatment furnace, comprise: burner 1, with burner 1 interconnective natural gas tube 2 and air hose 3, on described natural gas tube 2, be disposed with first gas electromagnetic valve 4, air-fuel ratio valve 5, hand-operated valve 6 and second gas electromagnetic valve 7, the other end of air hose 3 is provided with combustion fan 8 and variable-frequency motor, and air hose 3 is provided with air butterfly valve 9, and air hose 3 is connected with air-fuel ratio valve 5 by connecting pipe 10.
When the fuel gas heating energy-saving device in the above-mentioned heat-treatment furnace uses, give variable-frequency motor, adjust combustion fan 8 air quantity sizes according to temperature control instrument output simulation volume signal.After the controller of burner 1 started, first gas electromagnetic valve 4 and second gas electromagnetic valve 7 were opened, and ignition transformer is connected simultaneously, and pilot spark appears in the spray orifice position of burner 1.Open air butterfly valve 9, combustion fan 8 is set low hertz frequency by variable-frequency motor and is provided an amount of combustion air to burner.Connecting pipe 10 by air-fuel ratio valve 5 is regulated the outlet pressure of combustion gas side.If the natural gas heat-treatment furnace needs more thermic load, combustion fan 8 is heightened frequency automatically by variable-frequency motor and is provided more combustion air to burner 1, and the rising of the pressure of air side rises combustion gas side outlet pressure by the connecting pipe 10 of air-fuel ratio valve 5.Prove through practice: originally energy consumption per ton steel is on average at 30m
3, adopt variable-frequency motor to adjust the big or small energy consumption per ton steel later on of air quantity on average at 26m
3, saved the energy effectively.
The foregoing description is only for the usefulness that the present invention is described; and be not to be limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make various variations and modification, so all technical schemes that are equal to also should belong to protection category of the present invention.
