Description
Technical Field
The utility model relates to a technical field is administered to the flue gas, concretely relates to flue gas temperature automatic regulating apparatus.
Background
At present, because the fuel change of many large-scale power station boilers is large, a plurality of power stations need to burn two or more different fuels simultaneously, the flue gas temperature change generated when different fuels are burnt can be large, if the flue gas temperature at the inlet of a dust remover is too high, the fly ash in the dust remover is more than 10 in resistance11-1012And the dust removal efficiency of the dust remover is poor due to unfavorable working conditions such as severe spark discharge, back corona and the like easily occurring between omega cm.
The prior technical scheme is as follows: the flue gas temperature of the inlet of the dust remover is detected, the water amount sprayed into the inlet flue of the dust remover is controlled according to the measured flue gas temperature, the flue gas temperature of the inlet of the dust remover is reduced, and then the working parameters of the dust remover are manually adjusted. However, the scheme has the defects of complex operation, low efficiency, large manual error and the like.
SUMMERY OF THE UTILITY MODEL
In view of the above, the utility model aims at providing a flue gas temperature automatic regulating apparatus, when simultaneously burning with the undulant great of multiple different fuel temperature, can guarantee that the exhaust gas temperature is stable relatively.
In order to realize the technical purpose, the utility model discloses a scheme is: the utility model provides a flue gas temperature automatic regulating apparatus, includes boiler outlet flue, spray column, bypass flue, boiler outlet flue department be provided with first feedback signal, bypass flue exit be provided with second feedback signal, first feedback signal and second feedback signal generate temperature regulation signal, the spray column in set gradually one-level from top to bottom and spray the mechanism and the mechanism is sprayed to the second grade, the spray column that the one-level was sprayed above the mechanism is provided with the flue, the one-level sprays the spray column that mechanism and second grade sprayed between the mechanism and is provided with down the flue, last flue and lower flue be linked together with the bypass flue, last flue and lower flue in all be equipped with adjustable flue gas baffle.
Preferably, the first-stage spraying mechanism is formed by connecting a plurality of spraying pipelines in parallel, and each spraying pipeline is provided with a plurality of spray heads and an automatic water regulating valve.
The utility model discloses according to the regulation temperature signal, spray the size of mechanism water spray volume and through the flue gas flow in the upper and lower flue of control through the regulation to reach control outlet flue gas temperature's purpose, make outlet flue gas temperature relatively stable, in order to reach better dust removal, desulfurization effect, the utility model has the advantages of simple structure, adjust sensitive, control range is big, efficient.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the cross-sectional structure of the spraying mechanism of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the specific embodiment of the present invention is: the utility model provides a flue gas temperature automatic regulating apparatus, includes boiler outlet flue 1, spray column 11, bypass flue 8, boiler outlet flue 1 department be provided with first feedback signal, 8 exits in bypass flue be provided with second feedback signal, first feedback signal and second feedback signal generate temperature regulation signal, spray column 11 in set gradually one-level about in and spray mechanism 3 and second grade spray mechanism 2, spray column 11 that the one-level sprayed on mechanism 3 is provided with flue 4, the one-level sprays spray column 11 between mechanism 3 and the second grade spray mechanism 2 and is provided with down flue 5, flue 4 and down flue 5 be linked together with bypass flue 8, flue 4 and down flue 5 in all be equipped with adjustable gas baffle 6.
The primary spraying mechanism 1 is formed by connecting a plurality of spraying pipelines in parallel, and each spraying pipeline is provided with a plurality of spray heads 9 and an automatic water regulating valve 10.
In the use process, when the temperature adjusting signal is not very high, the valve of the adjustable flue gas baffle 6 in the upper flue 4 can be adjusted to be small or directly closed, the valve of the adjustable flue gas baffle 6 in the lower flue 5 is adjusted to be large or fully opened, and the water spraying flow of the secondary spraying mechanism 2 is automatically adjusted, so that the flue gas only flows through the secondary spraying mechanism 2, the temperature of the outlet flue gas is controlled, and the aim of relatively stabilizing the temperature of the outlet flue gas is fulfilled.
When the temperature adjusting signal is too high, the valve of the adjustable flue gas baffle 6 in the lower flue 5 can be adjusted to be small or directly closed, the valve of the adjustable flue gas baffle 6 in the upper flue 4 can be adjusted to be large or fully opened, and the water spraying flow of the first-stage spraying mechanism 3 and the second-stage spraying mechanism 2 is automatically controlled, so that the flue gas is cooled through two stages, and the aim of reducing the outlet temperature is fulfilled.
This application can be according to temperature regulation's signal, through the size of adjusting the mechanism water spray volume of spraying and through the flue gas flow in the upper and lower flue of control to reach control outlet flue gas temperature's purpose, make outlet flue gas temperature relatively stable, in order to reach better dust removal, desulfurization effect, this application has simple structure, adjusts advantages such as sensitive, control range is big, efficient.
The above, only do the utility model discloses a one of them embodiment, not be used for limiting the utility model discloses, all foundation the utility model discloses a technical entity all should be contained within the protection scope of the technical scheme of the utility model to any slight modification, equivalent replacement and improvement that the above embodiment was done.
