Fan inlet is connect with the outlet of supersonic speed low temperature dewatering device dry gas and second level gas-liquid separation upper end simultaneously, air outlet and chimney
Connection, second level knockout drum bottom end is connect with water tank.
Further, the supersonic speed low temperature dewatering device is by spiral stream guidance device, supersonic nozzle, liquid water collection chamber
Room and gradually-reducing-expanding type diffuser are constituted.
Further, the spiral stream guidance device is multiple-blade bevel-type symmetrical structure, and vane inlet angle is 90 °, outlet
Angle is 30 °, and fluid is made to obtain centrifugal acceleration.
Further, the supersonic nozzle is made of contraction section and expansion segment two parts, supersonic nozzle contraction section
Partial line style uses this pungent base curves of Vito, and supersonic nozzle expansion segment part is using cone section design.
Further, the gradually-reducing-expanding type diffuser is divided into expansion segment and contraction section, and structure is cone section line style,
It is mainly used to pressure recovery, reduces energy loss.
The utility model has the following beneficial effects:
(1) the characteristics of the utility model is according to the insulation constant entropy expansion of supersonic nozzle makes flue gas enter supersonic speed acceleration
Low temperature, the ultrasonic state of low pressure are formed after pipe, and the vapor in flue gas is enable to be condensed into liquid water to the greatest extent；
(2) in the utility model, liquid water, supersonic speed low temperature dewatering can be separated by level-one, second level knockout drum
Device then completes Water vapor condensation separation；
(3) the utility model will condense function and be integrated in one with separation function, and simple process, convenient operating maintenance takes off white
High efficiency, and environmental protection, are with a wide range of applications.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram for the system that white processing is taken off for flue gas of the utility model.
1- level-one knockout drum, 2- supersonic speed low temperature dewatering device, 3- spiral stream guidance device, 4- supersonic nozzle, 5- liquid
Tai Shui collection chamber, 6- gradually-reducing-expanding type diffuser, 7- air-introduced machine, 8- chimney, 9- second level knockout drum, 10- water tank
Specific embodiment
The detailed process of the utility model is illustrated by following implementation now in conjunction with attached drawing.
As shown in Figure 1, a kind of system for taking off white processing for flue gas includes level-one knockout drum 1, supersonic speed low temperature is de-
Water installations 2, second level knockout drum 9, air-introduced machine 7 and water tank 10.1 top of level-one knockout drum and supersonic speed low temperature dewatering fill
2 upstream connection is set, bottom end is connect with water tank 10, the liquid water out of supersonic speed low temperature dewatering device 2 and second level gas-liquid separation
Tank 9 connects；7 import of air-introduced machine connects with the outlet of 2 dry gas of supersonic speed low temperature dewatering device and 9 top of second level knockout drum simultaneously
It connects, air outlet is connect with chimney 8, and 9 bottom end of second level knockout drum is connect with water tank 10.
Supersonic speed low temperature dewatering device 2 is by spiral stream guidance device 3, supersonic nozzle 4, liquid water collection chamber 5 and it is tapered gradually
Expansion type diffuser 6 is constituted.
Spiral stream guidance device 3 is multiple-blade bevel-type symmetrical structure, and vane inlet angle is 90 °, and exit angle is 30 °, makes to flow
Body obtains centrifugal acceleration.
Supersonic nozzle 4 is made of contraction section and expansion segment two parts, and the line style of supersonic nozzle contraction section part uses
