The utility model aims at providing a thermal power generating unit and denitrification facility can improve denitrification facility operating efficiency.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
referring to fig. 1, the present embodiment provides a denitration device, which includes a flue component, a denitration component, a heat exchange component, a water supply pipeline 400, and an air pipeline.
The flue assembly comprises a main flue 110 and a flue gas bypass 120, both ends of the flue gas bypass 120 are communicated with the main flue 110, and the flue assembly is used for flue gas circulation.
It will be appreciated that when the flue gas bypass 120 is in communication with the main flue 110, the flue gas can flow not only along the main flue 110 but also along the flue gas bypass 120, and at this time, when both ends of the flue gas bypass 120 are in communication with the main flue 110, it can be seen that there may be two flow paths for the flue gas before entering the inlet of the flue gas bypass 120.
The denitration assembly is disposed in the main flue 110, and includes an economizer 210, a denitration member 220 and an air preheater 230, which are sequentially disposed along a flue gas flowing direction, and one end of the flue gas bypass 120 is located between the economizer 210 and the denitration member 220.
It can be understood that the sequence of the flue gas before and after flowing on the main flue 110 is the economizer 210, the denitration member 220 and the air preheater 230, both ends of the flue gas bypass 120 are communicated with the main flue 110, one end of the flue gas bypass 120 is located between the economizer 210 and the denitration member 220, when part of the flue gas flows along the flue gas bypass 120, the flue gas only passes through the denitration member 220 and the air preheater 230 and does not pass through the economizer 210, and therefore, the flue gas before entering the denitration member 220 contains the flue gas passing through the economizer 210 and the flue gas not passing through the economizer 210, so that the temperature of the flue gas entering the denitration member 220 is integrally improved compared with the temperature of the flue gas only passing through the economizer 210, and the normal operation of the denitration member 220 is well ensured under the condition of low-load operation of the denitration device.
The heat exchange assembly comprises a heat exchange bundle 310 and a heat exchange tube 320, wherein two ends of the heat exchange bundle 310 are respectively positioned in the main flue 110 and the heat exchange tube 320, and the heat exchange bundle 310 exchanges heat with the flue gas flowing out through the air preheater 230.
It will be appreciated that the heat exchange bundle 310 and the heat exchange tube 320 are used to collect heat of the high temperature flue gas flowing out through the air preheater 230, and then transfer the heat to the next process.
It should be noted that, the heat exchange bundle 310 is mainly used for exchanging heat with high temperature flue gas, and the heat exchange tube 320 mainly collects heat exchanged by the heat exchange bundle 310 and transfers the heat to the next process, and the heat exchange assembly may be replaced by other heat exchange devices, so long as the above purpose can be achieved.
The water supply pipe 400 is used for supplying water to the economizer 210, and the water supply pipe 400 is sequentially connected with the heat exchange pipe 320 and the economizer 210 along the water supply flow direction.
It can be understood that the effect of the economizer 210 is mainly to absorb the heat of the flue gas flowing through the economizer 210, when the water supply pipeline 400 is used for supplying water to the economizer 210, the heat of the flue gas absorbed by the economizer 210 can be used for heating the water supply, in addition, when the water supply pipeline 400 is sequentially connected with the heat exchange pipe 320 and the economizer 210 along the water supply flowing direction, the heat exchanged by the heat exchange bundle 310 and the high-temperature flue gas flowing out through the air preheater 230 is collected by the heat exchange pipe 320 and then transferred to the economizer 210 through the water supply pipeline 400, so that heat recovery is realized, heat waste is avoided, and the operation efficiency of the whole denitration device can be improved.
The air duct is used for ventilation, and is located at one end of the air preheater 230 facing away from the main flue 110.
It will be appreciated that the two ends of the air preheater 230 are respectively disposed in the main flue 110 and the air duct, and the air duct is used for passing air through the air preheater 230 when the air circulates along the air duct.
Specifically, when the denitration device operates under a lower load, the flue gas bypass 120 may introduce a part of flue gas before the flue gas does not pass through the economizer 210 to the inlet of the denitration device 220, at this time, the flue gas before reaching the inlet of the denitration device 220 includes the flue gas which does not pass through the economizer 210 to exchange heat and the flue gas which passes through the economizer 210 to exchange heat, the arrangement of the flue gas bypass 120 increases the overall temperature of the flue gas entering the denitration device 220, so that the denitration device 220 operates normally, and as the flue gas temperature increases, the flue gas temperature at the outlet of the tail heat exchange device air preheater 230 also increases, the heat exchange bundle 310 and the heat exchange tube 320 may collect and transfer the heat of the high-temperature flue gas after passing through the air preheater 230 to the water supply pipeline 400, and then the water supply pipeline 400 transfers the heat to the economizer 210 for heating the water supply passing through the economizer 210.
Preferably, the air duct includes a first air duct 510 and a second air duct 520, the second air duct 520 being located between the first air duct 510 and the main flue 110.

Preferably, the flue gas bypass 120 is provided with a switch valve, and the switch valve is used for controlling the opening and closing of the flue gas bypass 120.
It can be understood that the effect of the flue gas bypass 120 is mainly that when the denitration device is operated under low load, the whole temperature of the flue gas entering the denitration piece 220 is increased before the flue gas entering the denitration piece 220 through the part of the flue gas which is not cooled by the economizer 210 enters the inlet of the denitration piece 220, so that the denitration piece 220 can normally operate when the denitration device is operated under low load; when the denitration device is not in low-load operation, the temperature of the flue gas passing through the economizer 210 can meet the temperature of the flue gas required by normal operation of the denitration piece 220, and at the moment, the flue gas bypass 120 needs to be closed to avoid heat loss caused by the fact that part of the flue gas does not exchange heat through the economizer 210, so that a switch valve is required to be arranged on the flue gas bypass 120 and used for controlling the opening and closing of the flue gas bypass 120 so as to open the flue gas bypass 120 when the denitration device is in low-load operation; the flue gas bypass 120 is closed when the denitrification device is not in low load operation.
Preferably, the heat exchange bundle 310 is provided with a regulating valve 311 at one end of the main flue 110, and the regulating valve 311 is used for controlling the flue gas to flow through the heat exchange bundle 310.
It can be understood that the heat exchange bundle 310 is mainly used for exchanging heat with the high-temperature flue gas flowing out from the air preheater 230, when the heat exchange bundle 310 is provided with the adjusting valve 311 at one end of the main flue 110, the adjusting valve 311 can be adjusted according to different load operation states of the thermal power generating unit, so that the heat exchange bundle 310 is in an optimal heat exchange state, and in addition, the adjusting valve 311 can be adjusted according to the heat requirement of the economizer 210 on the heat exchange tube 320.
Preferably, heat exchange bundle 310 is a plurality of heat pipe heat exchangers.
It is to be understood that the heat exchange bundle 310 is used to absorb heat, and in this application, the heat exchange bundle 310 is preferably a plurality of heat pipe type heat exchangers, and the specific number of the heat pipe type heat exchangers can be adjusted according to actual needs, which is not specifically limited herein.
Preferably, a heat exchange working medium is arranged in the heat exchanger and used for exchanging heat with the flue gas discharged through the air preheater 230.
In this embodiment, the heat exchange bundle 310 is preferably a plurality of heat pipe heat exchangers, and a heat exchange working medium for exchanging heat with the flue gas is arranged in the heat exchangers, it can be understood that the heat exchange working medium only exchanges heat with the flue gas exhausted by the air preheater 230 and is not in direct contact with the flue gas exhausted by the air preheater 230, so that the heat exchange bundle 310 can have stronger heat exchange efficiency on one hand, and can avoid the risk of leakage of the flue gas on the other hand.
It should be noted that the material of the heat exchange medium may be adjusted according to actual requirements, and is not particularly limited herein, so long as the above objective can be achieved.
Preferably, the heat exchange tube 320 is used to collect heat absorbed by the heat exchange bundle 310, and the heat is transferred to the economizer 210 through the water supply line 400.
It is understood that the heat exchanged by the heat exchange bundle 310 needs to be collected by the heat exchange tube 320 disposed outside thereof, and the water supply line 400 sequentially passes through the heat exchange tube 320 and the economizer 210 along the water supply flow direction, and the heat collected by the heat exchange tube 320 can flow through the water supply in the water supply line 400 to the economizer 210.
It should be noted that, the heat exchange bundle 310 is close to one end of the water supply pipeline 400, and is not in direct contact with the water supply, so that the water supply resistance is prevented from being greatly increased while the heat exchange efficiency is high.
Preferably, the cross section of the flue gas bypass 120 along the flue gas flow direction is circular.
It can be appreciated that when the cross section of the flue gas bypass 120 along the flue gas flowing direction is circular, the flue gas flowing is facilitated, and the materials required for the flue gas bypass 120 can be saved.
Preferably, the flue gas bypass 120 has a diameter less than the diameter of the main flue 110.
It can be appreciated that, when the diameter of the flue gas bypass 120 is smaller than that of the main flue 110, the flue gas bypass 120 is more beneficial to playing a role of flue gas bypass, so as to avoid too much flue gas passing through the flue gas bypass 120, resulting in too little flue gas passing through the main flue 110 to reach the economizer 210 to exchange heat, and further affecting the heating of the feed water passing through the economizer 210.
