Abstract
The utility model relates to a device, namely an oxygen supply firepower furnace which can be controlled immediately. The method is characterized in that: a smoke residual oxygen detection sensor 7 is arranged in a flue 6 of the thermal kiln, the smoke residual oxygen detection sensor 7 is communicated with a computer control device 9 outside the kiln, and the computer control device 9 is communicated with a kiln air supply device 8. The residual oxygen detecting device 7 feeds back the oxygen content signal in the flue 6 to the computer control device 9 at any time, and the computer control device 9 sends an instruction to the air supply device 8 at any time to adjust the air supply volume, so that the oxygen volume in the kiln is kept at a proper level, the sufficient combustion can be ensured, the excessive intake air volume can be avoided, the temperature is reduced, the electric energy is wasted, and the energy-saving benefit is considerable.
Description
Technical field
The utility model relates to a kind of equipment, promptly a kind of oxygen supply firepower kiln of promptly controlling.
Background technology
At present, the firepower kiln that enterprises such as power plant, glass factory are used all will be to the combustion chamber blowing-in and combustion-supporting when operation.According to specification requirement, the air output of kiln can not be too many, more can not lack.Air-supply is the oxygen supply deficiency less, and it is insufficient to burn, and energy is wasted in air-supply at most, and can reduce ignition temperature.Therefore, on existing kiln, all is furnished with the surplus oxygen checkout equipment of flue gas, in order to grasp the situation of air output.Existing surplus oxygen checkout gear all can not be reported immediately, all is by people's chemical examination of according to circumstances sampling, and the aperture of air outlet is adjusted again.Because the oxygen supply situation of kiln changes at any time, the method for this irregular sampling analysis is difficult to the adaptive technique requirement, and kiln often burns under the situation of peroxide.It is reported, the air output of the large-scale firepower kiln of existing power plant and glass factory is many to be moved under 3-4 times situation of institute's required airflow, calculate with the aerial content of oxygen 20%, send into the unnecessary air quantity in the kiln and the heat that consumes because of air intake all is very considerable numeral.
Summary of the invention
The purpose of this utility model provides and a kind ofly can detect the surplus oxygen amount of flue gas at any time, and controls the i.e. control oxygen supply firepower kiln of air output automatically.
Above-mentioned purpose is realized by following technical scheme: develop a kind of oxygen supply firepower kiln of promptly controlling, be characterized in: the surplus oxygen acquisition sensor of flue gas is housed in the flue of this firepower kiln, the Computer Control Unit of surplus oxygen acquisition sensor of flue gas and kiln outside interrelates, and Computer Control Unit is connected with the kiln air-supply arrangement.
Said surplus oxygen acquisition sensor adopts platinum electrode earthenware probe.
Said Computer Control Unit adopts single-chip microcomputer as microprocessor and controller.
Said Computer Control Unit with the contact method of kiln air-supply arrangement is: the controller by single-chip microcomputer directly is connected with the frequency converter of fan electromotor.
Said Computer Control Unit with the contact method of kiln air-supply arrangement is: the controller by single-chip microcomputer directly is connected with the gauge tap of kiln air inlet.
Adopt the i.e. control oxygen supply firepower kiln of technique scheme, surplus oxygen sniffer arrives Computer Control Unit to the oxygen content signal feedback in the flue at any time, Computer Control Unit sends instruction to air-supply arrangement at any time, adjust air output, thereby make the amount of oxygen in the kiln remain on proper level, can guarantee sufficient combustion, can avoid intake to exceed standard again and reduce temperature and waste electric energy that energy-saving benefit is very considerable.
Description of drawings
Fig. 1 is the front view of a kind of embodiment;
Fig. 2 is the vertical view of this embodiment.
Among the figure as seen: kiln combustion chamber 1, air intake exhaust opening 2, jet 3, heat accumulation chamber 4, blower fan 5, flue 6, surplus oxygen acquisition sensor 7, motor 8, single-chip microcomputer 9.
The specific embodiment
Fig. 1,2 introduces a kind of kiln of floatation glass production line, be by a side jet 3 fuel oil to be sprayed onto combustion chamber 1 to burn, combustion air enters through air intake exhaust opening 2 from the heat accumulation chamber 4 of homonymy, flue gas is discharged from the air intake exhaust opening 2 of opposite side, stays heat through heat accumulation chamber 4 and discharges through following flue 6.Its improvement is: in the kiln outside, be provided with a cover Computer Control Unit.What adopt here is better simply single-chip microcomputer 9, in flue, the surplus oxygen acquisition sensor 7 of flue gas is housed.Here can adopt the surplus oxygen acquisition sensor 7 of commercially available automobile-used platinum electrode ceramic pipe type, its structural principle is, inside and outside coated platinum layer respectively at earthenware, form two platinum electrodes, because platinum electrode has strong catalytic action to oxygen, and the variation that in the decomposable process of oxygen molecule, produces electromotive force, thereby obtain the index of oxygen content.This index is passed to single-chip microcomputer, treatedly can send correct instruction, adjust air output at any time to air-supply arrangement.The air-supply arrangement here can be the frequency converter of air supply motor 8, also can be the switch of kiln air inlet.
