Abstract
The utility model discloses a device for automatically adjusting components of smoke on a water cooled wall of a lateral wall of a front-back-wall hedging combustion boiler, which comprises a smoke online analyzing device, a smoke continuous monitoring system, a hot air feeding device and a data processing analyzing control system. The smoke online analyzing device is connected with a data output end of the smoke continuous monitoring system through a data collecting channel and a signal input end of the data processing analyzing control system, a signal output end of the data processing analyzing control system is connected with a signal control end of the hot air feeding device, the hot air feeding device is arranged on the water cooled wall, and an air outlet of the hot air feeding device is aligned to the water cooled wall. The device can eliminate reducing atmosphere fast in real time and restrain H2S from being generated, pipes of the water cooled wall can not be changed because of high temperature reducing sulfur attacks, and therefore changing cost is saved, and boilers are guaranteed to operate safely and economically.
Description
Technical field
The utility model belongs to the Opposite Firing Boiler field, relates in particular to a kind of device that can regulate Opposite Firing Boiler water-cooling wall smoke components automatically.
Background technology
The characteristics of the front-back wall opposed firing of Opposite Firing Boiler cause flame impingement boiler side water wall, and a large amount of unburnt coal dusts burn herein, form strong reducing atmosphere: high CO concentration, low O
2Concentration.If the sulfur content that uses in the coal is higher, under the effect of reducing atmosphere, sulphur is prone to generate the very strong H of corrosivity
2S forms so-called high-temperature reductibility sulfur corrosion, thereby water-cooling wall tubing is had a negative impact.And the fume continuous monitoring system at desulphurization system place can only play monitoring desulphurization system inlet flue gas composition at present; Can't directly monitor the smoke components at water-cooling wall place; Do not control the function of smoke components automatically; When the water screen tube attenuate seriously just needs the large tracts of land replace tubes, therefore cause the running time of boiler short, have a strong impact on boiler safety, operation economically.
Summary of the invention
The purpose of the utility model provides a kind of device that can regulate Opposite Firing Boiler water-cooling wall smoke components automatically, and the boiler side water wall is not corroded, thereby makes boiler safety, operation economically.
The utility model adopts following technical proposals: a kind of device of automatic adjusting Opposite Firing Boiler side water wall smoke components; Comprise flue gas on-line analysis device, fume continuous monitoring system; Also comprise hot blast adding set and Data Management Analysis control system; The data output end of said flue gas on-line analysis device and fume continuous monitoring system is connected through the signal input part of data acquisition channel with Data Management Analysis control system; The signal output part of Data Management Analysis control system is connected with the signal controlling end of hot blast adding set, and the hot blast adding set is arranged on the water-cooling wall, and its air outlet is aimed at water-cooling wall.
The signal input part of Data Management Analysis control system also is connected through the data output end of data acquisition channel with unit operation control system.
The utility model can real-time collecting Opposite Firing Boiler water-cooling wall smoke components, unit operation parameter and fume continuous monitoring system operational factor; Carry out the parameter analysis then; Automatically control the smoke components that the hot blast adding set changes the boiler side water wall again; Can eliminate reducing atmosphere real-time, suppress H
2The generation of S can not changed the tubing of water-cooling wall because of the high-temperature reductibility sulfur corrosion, has both practiced thrift renewal cost, guaranteed again boiler can be safely, operation economically.

The specific embodiment
As shown in Figure 1; The device that the utility model is regulated Opposite Firing Boiler side water wall smoke components automatically comprises flue gas on-line analysis device, fume continuous monitoring system, hot blast adding set and Data Management Analysis control system; Flue gas on-line analysis device is installed on the side water wall 1; Be used for detecting smoke components; Fume continuous monitoring system is installed in the porch of desulphurization system; Desulphurization system porch flue gas is monitored, and the data output end of flue gas on-line analysis device and fume continuous monitoring system is connected through the signal input part of data acquisition channel with Data Management Analysis control system, and the signal input part of Data Management Analysis control system also is connected with unit operation control system through data acquisition channel; The signal output part of Data Management Analysis control system is connected with the signal controlling end of hot blast adding set; Wherein Data Management Analysis control system adopts single-chip microcomputer or computer; The hot blast adding set is a mature technology; It is arranged on outside the side water wall 1, and air outlet is aimed at side water wall 1, regulates the hot blast rate that its valve opening can be controlled its output.
When utilizing said apparatus to automatically adjust Opposite Firing Boiler side water wall smoke components, through being installed in the flue gas on-line analysis device test smoke components on the side water wall 1, like O
2, CO
2, CO, H
2S; Simultaneously through unit operation control systematic collection unit operation parameter, like unit load, furnace outlet oxygen amount, total fuel quantity, milling systems mode, coal-supplying amount, secondary wind air distribution mode, secondary air separating air quantity, secondary air separating air door baffle opening; Also collect the fume continuous monitoring system operational factor, like desulphurization system inlet SO
2Concentration of emission, flue gas oxygen content, total exhaust gas volumn; Above-mentioned data are delivered to Data Management Analysis control system through data acquisition channel; The side water wall smoke components of collecting, unit operation parameter and fume continuous monitoring system operational factor are screened by Data Management Analysis control system; Filter out the parameter that to judge: judge then; And the output control signal corresponding makes the valve of hot blast adding set transfer to maximum or aperture minimum or that adapt to, the smoke components of change side water wall 1 position to the hot blast adding set.
Claims (2)
1. device of automatically regulating Opposite Firing Boiler side water wall smoke components; Comprise flue gas on-line analysis device, fume continuous monitoring system; It is characterized in that: also comprise hot blast adding set and Data Management Analysis control system; The data output end of said flue gas on-line analysis device and fume continuous monitoring system is connected through the signal input part of data acquisition channel with Data Management Analysis control system; The signal output part of Data Management Analysis control system is connected with the signal controlling end of hot blast adding set, and the hot blast adding set is arranged on the water-cooling wall, and its air outlet is aimed at water-cooling wall.
