For the tail vapour of group drying cylinder discharge by connected adjustable heat pump after steam-water separator, the Adjustable Heat Pump connects high steam, institute
The indirect steam for stating condensate water pot is back to the heating system of single group drying cylinder after Adjustable Heat Pump pressurizes.
Preferably, being also associated with exhaust flow detection device and pressure-control valve, the pressure on the single group drying cylinder
Control valve is connected with pressure controller, and the pressure controller is used to control the pressure of single group drying cylinder, the exhaust flow detection
Device is connected with tail vapour cycle flow controller, and the tail vapour cycle flow controller is used to control the tail steam flow of Adjustable Heat Pump
Amount, the tail vapour cycle flow controller, pressure controller select selector to be connected with low.
Preferably, being also associated with condensed water elimination valve and liquid level gauge on the condensate water pot.
The beneficial effects of the utility model：The utility model passes through Adjustable Heat Pump, single group drying cylinder, condensate water pot and condensation
Multi-section series heat supply is changed to Adjustable Heat Pump by the cooperation of water pump etc., i.e., increases by one on every section of steam-supplying system steam
Adjustable Heat Pump, and high steam is connected, the indirect steam of condensate water pot is back to this section of heating system after heat pump pressurizes,
Multi-stage series formula heat supply becomes the parallel heat-supplying mode of multistage heat pump before being allowed to, and each section of heat supply independence can be dried with effective solution
Cylinder drainage problem improves paper machine operation speed, stability, saves steam consumption, reduces the comprehensive energy consumption of paper machine.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
【Description of the drawings】
Fig. 1 is a kind of flow diagram of Dryer Section of Paper Machine Analysis of Heat Pump Drying System of the utility model.
【Specific implementation mode】
Refering to fig. 1, a kind of Dryer Section of Paper Machine Analysis of Heat Pump Drying System of the utility model, including Adjustable Heat Pump 1, single group drying cylinder
2, condensate water pot 3 and condensate pump 4, the Adjustable Heat Pump 1 are connected with single group drying cylinder 2, the single group drying cylinder 2 and condensate water pot
3 are connected, and the condensate water pot 3 is connected with condensate pump 4, and steam-water separator is connected on the single group drying cylinder 2, and the single group is dried
For the tail vapour that cylinder 2 is discharged by connected adjustable heat pump 1 after steam-water separator, the Adjustable Heat Pump 1 connects high steam, described
The indirect steam of condensate water pot 3 is back to the heating system of single group drying cylinder 2 after the pressurization of Adjustable Heat Pump 1.The single group is dried
Exhaust flow detection device and pressure-control valve are also associated on cylinder 2, the pressure-control valve is connected with pressure controller, described
