Corrugated board production line speed is higher, and the heating temperature of corrugation equipment just needs synchronous raising.In order to energy saving, at present in industry
It is all working hard in index of the bonding with glue by every means always, to use steam temperature to reduce corrugated paper board production line
Degree, improves efficiency, and reduces production cost.However, being reduced using steam pressure, the return water collection work of condensed water but occurs
The undesirable problem of effect.Past, since boiler use cost is lower, condensed water is mostly nature discharge.Now, it fires
Coal burning boiler is all replaced by natural gas boiler, and use cost improves 4 times or more, for this purpose, most effective Compensation measures are exactly to condense
Watertight recycling, the use cost of combustion gas is reduced with this.
The condensing hot air furnace of corrugated paper board production line at present entirely uses the closed way of recycling of positive pressure, that is, condensed water
In collecting tank, condensed water is pressed back into boiler room using the steam pressure that equipment works.Positive pressure recycles usual pressure limit all
Between 0.2-0.3MPa, but at present gradually for the corrugated paper board production line using low pressure operation, this 2-3 kilograms outer
Pressure will increase biggish back pressure to the drain valve of heating equipment, causes to cause large effect to condensed water elimination effect, lead
It causes the condensed water elimination in heating equipment difficult, cannot in time, fully emit, seriously affect the heating of heating equipment
Effect.What corrugated board production was leaned on is exactly the high temperature of Corrugator roller and pressure roll boxboard and corrugated paper are quickly bonded in one
It rises, thus it is possible to the no stabilization for keeping high efficiency and bonding effect, the temperature of heating roller is stable and heating is averagely one crucial
Technical essential.Therefore, it should guarantee the normal work of corrugated board production, reach the energy consumption for reducing corrugated board production again,
It is the project of those skilled in the art's research.

Specific embodiment
It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, corrugated paper board production line condensed water negative pressure recovery system of the present invention, including have insulating layer
Drainer 3, negative pressure constant-pressure tank 6, water collect tank 7, buffering water pot 14, high temperature and pressure water pump 15；3 cavity of resorption of drainer passes through drain valve
2 are connected with corrugated paper board production line condensing water conduit, are connected by water siphunculus 5 with 6 cavity of resorption of negative pressure constant-pressure tank, drainer 3
Epicoele is connected by gas siphunculus 7 with 6 epicoele of negative pressure constant-pressure tank, is provided in the middle part of 3 inner cavity of drainer by stainless steel wire system
At spongy condensate 4；6 cavity of resorption of negative pressure constant-pressure tank is connected by pipeline with 8 import of pneumatic diaphragm pump, negative pressure constant-pressure tank 6
Epicoele is connected by exhaust pipe 9 with 8 import of pneumatic diaphragm pump, and water level upper limit sensor is provided in negative pressure constant-pressure tank 6
With water level lower limited sensor；The outlet of pneumatic diaphragm pump 8 is connected by aqueduct 10 with 11 inner cavity of water collect tank；Water collect tank 11
Epicoele and cavity of resorption pass through gas siphunculus 13 and water siphunculus 12 respectively and are connected with the epicoele and cavity of resorption for buffering water pot 14, are located at buffered water
Exhaust pipe 17 is provided at the top of tank 14, the cavity of resorption of buffering water pot 14 is connected by pipeline with 15 import of high temperature and pressure water pump
Logical, the outlet of high temperature and pressure water pump 15 is connected by pipeline 16 with the water chamber of boiler.
Working principle of the present invention is summarized as follows:
The condensation by mixing water 1 generated in corrugated paper board production line heating equipment is discharged into drainer 3 by drain valve 2, liquid
Condensed water 1 be concentrated in the lower part of drainer 3, flash steam and incondensable gas are then raised above, and are located at drainer 3 encountering
Inner cavity top made of stainless steel wire when spongy condensate 4, coagulable flash steam flows to drainer 3 by condensation again
Lower part assemble, the air and carbon dioxide gas that cannot condense then are gathered in the top of drainer 3；3 lower part of drainer it is cold
Condensate 1 is balanced by water siphunculus 5 and is flowed in negative pressure constant-pressure tank 6, and the incondensable gas on top is then by being connected to 3 He of coagulation tank
Negative pressure constant-pressure tank) at the top of gas siphunculus 7 be discharged into negative pressure constant-pressure tank 6 and assemble；The condensed water 1 of 6 inner cavity lower part of negative pressure constant-pressure tank
It is conveyed outward by pneumatic diaphragm pump 8；The incondensable gas for combining in 6 inner cavity top of negative pressure constant-pressure tank passes through exhaust pipe 9 by gas
Dynamic diaphragm pump 8 conveys outward together with condensed water, and the condensation by mixing water pumped out by pneumatic diaphragm pump 8 is defeated by conveyance conduit 10
It is sent in the water collect tank 11 of boiler room；Intracavitary condensed water is equilibrated in buffering water pot 14 by water siphunculus 12 under water collect tank 11；
Intracavitary gas is equilibrated in surge tank 14 by gas siphunculus 13 on water collect tank 11；The condensed water 1 combined in surge tank 14 then leads to
It crosses high temperature high voltage resistant water pump 15 to be pressed into the water chamber of boiler, the exhaust gas for combining in 14 epicoele of surge tank then passes through exhaust pipe
17 exhaust.So far, entire condensed water negative pressure recycling operation is completed.Boiler can evaporate the water of same amount when producing steam,
So moisturizing must be just carried out continuously, boiler for producing steam is recycled to condensing hot air furnace in principle, just as in-engine profit
The system that the machine oil of sliding system equally forms an Infinite Cyclic.
The formation of condensed water negative pressure recovery system subnormal ambient of the present invention is generated using pneumatic diaphragm pump 8, pneumatically
Pressure in closed drainer 3 and negative pressure constant-pressure tank 6 is also become negative while being pumped condensed water 1 by diaphragm pump 8
Pressure.Since pneumatic diaphragm pump 8 belongs to pneumatic mode, it, will not gradually subtracting because of pressure with certain cushion performance
It is small and come to harm like that electric water pump.Meanwhile the structure of pneumatic diaphragm pump 8 also allows biggish resistance occur to be formed, because
This, which is the technology mode that most suitable elastic negative pressure generates.
