Amount, the tail vapour cycle flow controller, pressure controller select selector to be connected with low.
Preferably, condensed water elimination valve and liquid level gauge are also associated on the condensate water pot.
Beneficial effects of the present invention：The present invention passes through Adjustable Heat Pump, single group drying cylinder, condensate water pot and condensate pump etc.
Cooperation, Adjustable Heat Pump is changed to by multi-section series heat supply, i.e., increases an adjustable heat on every section of steam-supplying system steam
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, more before being allowed to
Section tandem heat supply becomes the parallel heat-supplying mode of multistage heat pump, and each section of heat supply independence can effectively solve drying cylinder draining and ask
Topic improves paper machine operation speed, stability, saves steam consumption, reduces the comprehensive energy consumption of paper machine.
The feature and advantage of the present invention 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 present invention.
【Specific embodiment】
Refering to Fig. 1, a kind of Dryer Section of Paper Machine Analysis of Heat Pump Drying System of the present invention, including Adjustable Heat Pump 1, single group drying cylinder 2, cold
Condensate tank 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 3 phase of condensate water pot
Even, the condensate water pot 3 is connected with condensate pump 4, and steam-water separator, the single group drying cylinder 2 are connected on the single group drying cylinder 2
For the tail vapour of discharge by connected adjustable heat pump 1 after steam-water separator, the Adjustable Heat Pump 1 connects high steam, described cold
The indirect steam of condensate tank 3 is back to the heating system of single group drying cylinder 2 after the pressurization of Adjustable Heat Pump 1.The single group drying cylinder 2
On be also associated with exhaust flow detection device and pressure-control valve, the pressure-control valve is connected with pressure controller, the pressure
Force controller is used to control the pressure of single group drying cylinder 2, and the exhaust flow detection device is connected with tail vapour cycle flow controller,
The tail vapour cycle flow controller is used to control the tail steam flow amount of Adjustable Heat Pump 1, the tail vapour cycle flow controller, pressure
Force controller selects selector to be connected with low.Condensed water elimination valve and liquid level gauge are also associated on the condensate water pot 3.
The course of work of the present invention：
A kind of Dryer Section of Paper Machine Analysis of Heat Pump Drying System of the present invention is in operation principle：First function of Adjustable Heat Pump 1
It is the drainability for adjusting cylinder group, second function of Adjustable Heat Pump 1 is that the tail vapour that single group drying cylinder 2 is discharged passes through carbonated drink point
Hot compression is carried out to it using a small amount of high steam by heat pump from after device, then 100% single group drying cylinder 2 is returned and is followed
Ring utilizes.The draining of the bigger drying cylinder of drying cylinder tail vapour cycle amount is better, in order to ensure that the effective draining of drying cylinder and tail vapour 100% recycle
It utilizes.Each cylinder group is equipped with drying cylinder tail vapour cycle flow inspection control loop and pressure control loop, the two are controlled back
The signal that road is exported be sent to one it is low select selector, relatively low signal controls heat pump effective, each signal is also simultaneously
It is sent to its opposite valve for pressure difference (exhaust-valve) or pressure-control valve (steam replenishment valve).Under normal operating conditions, it is relatively low
DPIC signals (tail vapour cycle flow controller) control heat pump, and heat pump is used for recycling and compresses tail steam flow amount and maintenance without standard-sized sheet
Control.PIC (pressure controller) exports high RST to pressure-control valve to control the pressure of drying cylinder.Heat pump only supplies a small portion
To each cylinder group (account for about each cylinder group steam consumption 20% or so), rest part needs to steam supplement the steam divided
Steam valve opens the pressure to maintain the cylinder group set.
Above-described embodiment is the description of the invention, is not limitation of the invention, it is any to simple transformation of the present invention after
Scheme all belong to the scope of protection of the present invention.
