Description
Technical field
The present invention relates to a kind of flue gas desulfur device that is used for power plant's limestone-gypsum wet flue gas desulfurizer (WFGD) or association area, relatively have system architecture smoothness, easy to maintenance, investment and the low characteristics of operating cost with the flue gas desulfur device of routine.
Background technology
Whole flue gas desulfur device is positioned at after flue end, the electric cleaner in known this field at present.Generally, the requirement according to self of each operating unit equipment of forming this process system is arranged in the zone of concentrating relatively.According to the process system requirements of process, by the supercharging of flue introducing desulfurization blower fan, the cooling of smoke re-heater (GGH) cooling side is introduced by flue in the back to the dirty flue gas after the dedusting earlier, enters the absorption tower by the flue introducing again and carries out the desulfurization washing.Flue gas after the desulfurization is discharged from the absorption tower, and the clean flue gas of discharge is introduced GGH heated side heating back by flue and introduced smoke stack emission by flue.There is following shortcoming in this design: be connected with the diffusion profile facility because the space length between the blower fan, desulfurization, all unit interfaces of heat exchange is collected by flue and the flue gas that matches with it, though utilize the linkage function of flue to satisfy the requirement of technological process and apparatus arrangement simultaneously, but because flue and the flue gas that matches are with it collected and the diffusion profile facility is bulky, the expenditure of construction height, particularly clean flue need be implemented expensive preservative treatment, thereby has increased investment and floor space; Simultaneously also increase consequent flow of flue gas resistance, made operating cost improve.
Summary of the invention
Technical problem: in order to overcome the problem that existing design exists, the invention provides a kind of compact, low consumption flue gas desulfur device, this design can reduce the floor space of whole system, it is compact to make whole system connect, SR reduces, and reduces the investment and the operating cost of whole device thus.
Technical scheme: compact of the present invention, low consumption flue gas desulfur device are made up of flue, dirty gas baffle door, desulfurization blower fan, smoke re-heater, absorption tower, chimney, clean gas baffle door, by-pass damper door; In flue, be provided with by-pass damper goalkeeper horizontal flue and be divided into air inlet section and the section of giving vent to anger two parts, the air inlet of desulfurization blower fan is provided with dirty gas baffle door and is connected with the air inlet section of flue, the gas outlet of desulfurization blower fan is connected with smoke re-heater temperature descending section in the smoke re-heater, the gas outlet of smoke re-heater temperature descending section is connected with the absorption tower, smoke re-heater in the gas outlet on absorption tower and the smoke re-heater section that heats up is connected, the outlet of smoke re-heater intensification section is provided with clean gas baffle door and is connected with the section of giving vent to anger of flue, and the section of giving vent to anger of flue is connected with chimney.The import of desulfurization blower fan is near the air inlet section of horizontal flue, vertical or the close smoke re-heater temperature descending section of the outlet that is in tilted layout of blower fan, the outlet of smoke re-heater intensification section is near the section of giving vent to anger of horizontal flue, smoke re-heater is vertical with flue with the absorption tower line of centres, only links to each other with a spot of linkage section between each unit.
The present invention has more reasonably arranged device location according to the characteristics of each key equipment.Each unit is imported and exported and is pressed the flue gas flow order into and out of linking, (look actual conditions and also can adopt V-arrangement) layout takes the shape of the letter U, the first unit import of WFGD device technique flow process is the device import, and the end unit outlet of technological process is the device outlet.Each unit also utilizes itself huge size to bear the function that the part flow process connects, thereby significantly reduced connection flue length except will realizing itself function, and is compact so that system connects.Specific as follows: undressed dirty flue gas at first enters the import of desulfurization blower fan from FGD device import baffle door, utilizes desulfurization blower fan body to connect smoke re-heater import bellows as the outlet of flue blower fan through transition circumference joint and enters the heat release of GGH temperature descending section.Flue gas after the cooling enters the absorption tower and carries out the desulfurization washing.Flue gas after the desulfurization is discharged from the absorption tower, and the clean flue gas of discharge enters smoke re-heater intensification Duan Zaire by smoke stack emission.
Beneficial effect:, saved investment and floor space because the layout compactness of system has reduced flue gas collection and diffusion profile facility that flue huge between present known each technology connects and matches with it; Simultaneously also reduce consequent flow of flue gas resistance, saved operating cost; Moreover each big unit equipment room is U (V) shape to be arranged, the spacious favourable repair and maintenance of outer space.
