Description
Technical field
The utility model relates to the burner design of control automatically in the industrial furnace equipment, refers in particular to the volume adjusting apparatus during high-temp combustion device, gas burner, fuel oil burner etc. are controlled automatically in the industrial furnace.
Background technology
At present, burner automatically in the control air quantity regulate the general air door actuator that adopts, the burner blower fan is power frequency operation always, when burning load hour, the air door actuator reduces aperture, but the most of energy of the blower fan of power frequency operation flogs a dead horse, it is big that energy is economized consumption; Simultaneously, close hour at air door, can produce blower fan and utter long and high-pitched sounds and wait noise, blower fan is when power frequency operation, and the noise of self generation is also very big; Burner in the industrial furnace for energy-conservation, supplies the air of burning most of through preheating; The temperature that has if continue the regulative mode with the air door actuator, will increase cost up to 600 ~ 800 ℃ greatly; And at high temperature the life-span lacks, and is difficult to reach the purpose of automatic control.
Summary of the invention
The purpose of the utility model is to improve and innovate to the defective that exists in the background technology and problem; Provide a kind of efficient, energy-conservation, eliminate noise in the fan operation, realize that the burner air quantity is regulated automatically under the high temperature air, reach energy-saving and environmental protection, stable, variable frequency adjustment is controlled the high-temp combustion device automatically reliably.
The technical scheme of the utility model is a kind of high-temp combustion device of structure, and it comprises burner blower fan, Frequency Converter Control cabinet, high-temp combustion device, gas ignition burner and gas valve group, wherein:
Described gas valve group comprises little thermoelectricity magnet valve, big fire magnetic valve and the emergency cut-off magnetic valve that is arranged on the high-temp combustion device combustion gas trunk line, and is arranged on the igniter solenoid valve on the ignition feed channel;
Described Frequency Converter Control cabinet connects little thermoelectricity magnet valve big fire magnetic valve of control and burner blower fan; And accomplish the Load Regulation of large and small fire by the frequency of the corresponding magnetic valve of the frequency of the frequency converter in the Frequency Converter Control cabinet; With Frequency Converter Control burner blower fan, regulate the air quantity of burner through the operating frequency that changes frequency converter.A certain frequency must be to a certain air quantity, with the corresponding fuel quantity of air quantity then can be a formula or continuous, not only can regulate continuously but also can carry out a formula control burner like this.Be characterized in:
Reduce to start the impact of big electric current during fan starting, had the function of soft start;
The ratio of fuel and air quantity is regulated, and has exempted blower fan and under power frequency, has moved for a long time, and the noise when having reduced operation has simultaneously reached energy-saving effect;
Through changing the frequency adjustment intake, need not control valve in the air channel through the high temperature air of preheating, can regulate the burner air amount easily, make the high-temp combustion device automatically control become possibility, also reduced cost simultaneously greatly;
Through setting fixed frequency, can be easily carry out proportioning and position formula control with fuel is corresponding one by one;
The utility model patent has following advantage and beneficial effect:
1, the utility model is energy-conservation: same typhoon machine, and during 100% rotating speed flow, shaft power is 100%; During 50% rotating speed flow, shaft power reduces to 50%; If adopt baffle plate, valve controls to 50% flow, still needs to suck from electrical network the power of 70-80%; If adopt the slippage poor efficiency, then need suck about 25% power from electrical network at a high speed to 50%; If adopt the efficient speed governing of frequency converter to 50% flow, only need to suck 10% power from electrical network, energy-saving effect is obvious;
2, the utility model environmental protection: blower fan is turned down air quantity through baffle plate when power frequency operation, and can produce the noise of uttering long and high-pitched sounds this moment, and frequency converter is regulated air quantity and then can be abated the noise;
3, the utility model is reliable and stable: adopt frequency converter to regulate air quantity, in the air channel, saved control valve, increased the stable and reliability of equipment greatly;
