Abstract
The present invention belongs to the field of paper-making machine technology. It is a steam-boil drying device system by means of combustion outside cylinder, and is characterized by that it uses combustion furnace outside cylinder, evaporator, raw materials steam-boil vessel, drying cylinder and chimney, and in order to raise combustion gas carrying and suction capability and secondary combustion oxygen-supply the top of its combustion furnace is equipped with sprayer and blower, and a steam-water separator is placed between the evaporator and steam-boil vessel so as to fully use softened water and increase steam quantity, and the interior of the drying cylinder is equipped with a combustion gas inducer so as to raise drying effect.
Description
The invention belongs to the papermaking equipment technical field, is a kind of cylinder external burning type papermaking digesting drying system device.
The existing thermal center energy paper machine that revolves, the patent No. 94206356,2, its drying unit adopts combustion furnace is set in drying cylinder.Because combustion furnace is located in the drying cylinder; must make fuel with the anthracite coke; fuel band is restricted; this fuel valency height in short supply adds charcoal and slags tap and need shutdown carry out, and reduces effective production time; this combustion gas thermal source can not the boiling raw material; can only dry by regenerated papermaking,, need join boiler in addition and produce steam as the boiling raw material.
The purpose of the invention is that design a kind ofly can be dried uncoated paper with combustion gas, again can be with the heating plant of vapour cooking raw material.
The technical scheme that the invention is taked is, adopts cylinder external burning stove, evaporimeter, material cooking pond, drying cylinder, chimney, between be communicated with carrier pipe.In order to improve combustion gas carrying capacity and secondary oxygen supply, above the cylinder external burning stove, be equipped with injector, air blast, in order to make full use of soft water, improve quantity of steam, between evaporimeter and material cooking pond, connect and establish steam-water separator,, the combustion gas air deflector is set in drying cylinder in order to improve the drying effect of combustion gas, in order to make full use of waste heat, waste-heat recoverer is set outside chimney.
The invention is compared with existing in-cylinder combustion formula drying unit, has following remarkable advantage.
1, because the present invention adopts the cylinder external burning stove, can bituminous coal be fuel, fuel consumption can reduce more than two times.
2, a thermal source can be dried uncoated paper with combustion gas, can use the vapour cooking raw material again, does not need to establish in addition boiler, has reduced equipment investment, has reduced cost of material again, and wheat straw raw material reduces about 10 times than wastepaper as raw material cost;
3, coal is slagged tap and is not shut down, and has increased effective production time;
4, because the combustion chamber is not limited by the cylinder internal volume, and heat capacity is unrestricted, production capacity improves more than 25%;
5, the workshop condition health is good, and noise reduces.
Reach example in conjunction with the accompanying drawings and further specify specific structural features of the present invention.
Accompanying drawing is represented the general structure schematic diagram of cylinder external burning type digesting drier for paper making of the present invention.
Referring to accompanying drawing, the present invention includes, cylinder external burning stove 1, carrier pipe 4, evaporimeter 5, material cooking pond 6, drying cylinder 8, chimney 11, combustion furnace 1 are located at outside the drying cylinder 8, are communicated with combustion gas carrier pipe 4 between combustion furnace 1, evaporimeter 5, the drying cylinder 8.Be communicated with steam pipeline 4 between evaporimeter 5 and the material cooking pond 6.In order to improve combustion gas delivery attraction power and second-time burning oxygen supply, injector 3 and air blast 2 are set in the top side of combustion furnace 1, the negative pressure cavity end opening of injector 3 is communicated with combustion furnace 1 top mouth, right mouthful is communicated with combustion gas carrier pipe 4, and the left side mouthful (air inlet) of jet blower connects air blast 2 outlets in its literary composition.Evaporimeter 5 adopts the jacket type evaporimeter, and water inlet connects hose, in order to make full use of soft water, improves quantity of steam, between steam (vapor) outlet and material cooking pond 6 steam-water separator 7 is set.Drying cylinder 8 two ends adopt flexible connection rotatable, in order to improve the drying effect of combustion gas, combustion gas air deflector 9 is set in drying cylinder 8, air deflector 9 is the tubular that an end seals an end opening, openend scoops out the outlet of combustion gas carrier pipe 4, the import of the corresponding chimney 11 of blind end, at the bottom of the blind end to projecting inward be good.In order to make full use of the chimney waste heat, outside chimney 11, be provided with hot water jacket 10 recovery waste heats.
The present invention is suitable for the technological transformation in middle-size and small-size paper mill, realizes that once material cooking, uncoated paper dry whole thermals source required in the whole paper technology, especially the desirable renewal product of papermaking equipment.
Claims (3)
1, a kind of cylinder external burning type digesting drier for paper making, it is characterized in that adopting cylinder external burning stove, evaporimeter, material cooking pond, drying cylinder, chimney, combustion furnace is located at outside the drying cylinder, be communicated with the combustion gas carrier pipe between combustion furnace, evaporimeter, the drying cylinder, be communicated with steam pipeline between evaporimeter and the material cooking pond.
