Including a gasifying pot, connected between a gasifying pot and the 3rd group of drying cylinder by condensate pipe, a gasifying pot upper end passes through
Steam pipe is communicated to second group of drying cylinder, in addition to condensate water pot, and a described vaporization pot bottom connects cold by condensate pipe
Solidifying water pot, in addition to No. two gasifying pots, are connected, No. two between the bottom of second group of drying cylinder and No. two gasifying pots by condensate pipe
Connected between gasifying pot and condensate water pot by condensate pipe, steam is passed through between the upper end of No. two gasifying pots and first group of drying cylinder
Pipe is connected, and first group of drying cylinder lower end connects condensate water pot, in addition to fourdrinier part steam-water separation tank by condensate pipe, and described is cold
It is solidifying to be connected between water pot and fourdrinier part steam-water separation tank by condensate pipe.
It is mounted on controlling the magnetic valve that whether condensate pipe is connected and flow is controlled, each electromagnetism on each condensate pipe
Valve is connected and is controlled by the controller with controller.
The back pool of sizing mixing for reclaiming the water in condensate water pot is connected with by pipeline in condensate water pot lower end.
Second group of described drying cylinder is connected with vapour source by steam pipe, and is provided with magnetic valve on the steam pipe, electricity
Magnet valve is connected and is controlled by the controller with controller.
Hydraulic valve is installed on each jet chimney.
Safety valve and pressure gauge are mounted on each gasifying pot.
The beneficial effects of the utility model：The utility model is due to using set vapour segmentation steam supply technology, except the 3rd group of drying cylinder
Directly heated with steam outer, remaining drying cylinder is heated using remaining vapour completely, compared with original steam supply way steam-saving rate up to 25% with
On, whole year saves 560,000 yuan or so of production cost.Due to covering the use of vapour, the pressure differential of drying cylinder import and export is increased, makes drying cylinder
Draining is more smooth, and dryer temperature is stable.Pass through automatic filling device, it is ensured that the stabilization of cylinder dried curve, it is to avoid artificial behaviour
Make the deviation brought, greatly improve finished product pulpboard moisture content uniformity, improve the quality of pulpboard, obtain user's favorable comment.
