Description
Technical field
The utility model relates to a kind of corrugated paper board production line steam energy-saving control device.
Background technology
Now in the corrugated board production, Corrugator roller, hot plate, what pressure roll and preheating cylinder etc. passed into all is fresh vapours, but single watt of machine preheating cylinder (greatly) does not generally need too high temperature, temperature is generally about 100～140 ℃ and gets final product, the temperature of the condensation water and steam of draining from Corrugator roller and pressure roll generally also can both be above 100 ℃, so this utilization condensed water (and water vapour), suitably replenish again the use that a small amount of live steam can satisfy preheating cylinder fully, and the existing equipment technology is that the condensation water and steam generally all is directly to have drained after producing, and causes the significant wastage of the energy.
Summary of the invention
For above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of corrugated paper board production line steam energy-saving control device, can effectively solve the problem of condensed water waste in the existing corrugation production.
The technical scheme of its solution is, comprise flash tank, preheating cylinder and stop valve, the stop valve of the first flash tank on pipeline and pipeline links to each other with the air intake of four preheating cylinders respectively, the drain valve of the venthole of four preheating cylinders on pipeline and pipeline links to each other with the second flash tank, with on the pipeline that the air intake of four preheating cylinders links to each other heat pump is housed, heat pump links to each other with the live steam pipeline through electric control valve, in one of them preheating cylinder temperature sensor is housed, temperature sensor, heat pump links to each other with the PLC controller with electric control valve, the first stop valve is housed on the condensate pipe, three stop valve of the air intake of the first flash tank on pipeline and pipeline links to each other with condensate pipe, its junction places the front portion of the first stop valve, the leakage fluid dram of the first flash tank and the second flash tank respectively drain valve on pipeline and pipeline links to each other with condensate pipe, and the junction of itself and condensate pipe all places the rear portion of the first stop valve.
The utility model novel structure is unique, and is easy to use, good energy-conserving effect.
Description of drawings
Fig. 1 is the johning knot composition between each parts of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further details.
Provided by Fig. 1, the utility model comprises flash tank, preheating cylinder and stop valve, the stop valve of the first flash tank 1 on pipeline and pipeline respectively with four preheating cylinders 2,3,4 link to each other with 5 air intake, four preheating cylinders 2,3,4 link to each other with the second flash tank 6 with 5 the drain valve of venthole on pipeline and pipeline, with on the pipeline that the air intake of four preheating cylinders links to each other heat pump 7 is housed, heat pump 7 links to each other with live steam pipeline 8 through electric control valve 12, in one of them preheating cylinder temperature sensor is housed, temperature sensor, heat pump 7 links to each other with PLC controller 14 with electric control valve 12, the first stop valve 10 is housed on the condensate pipe 9, three stop valve 13 of the air intake of the first flash tank 1 on pipeline and pipeline links to each other with condensate pipe 9, its junction places the front portion of the first stop valve 10, the leakage fluid dram of the first flash tank 1 and the second flash tank 6 respectively drain valve on pipeline and pipeline links to each other with condensate pipe 9, and the junction of itself and condensate pipe 9 all places the rear portion of the first stop valve 10.
In order to guarantee result of use, on the pipeline of said four preheating cylinders 2,3,4 and 5 venthole a stop valve in parallel with drain valve is housed respectively, and the second stop valve 11 through connecting links to each other with the second flash tank 6, use drain valve during normal production, close with go out vapour gas port pipeline on the stop valve in parallel with drain valve.
Said heat pump 7 is steam ejector, and heat pump 7 is regulated the live steam flow through electric control valve 12 and realized the steam ejection effect; PLC controller 14 is controlled the aperture of electric control valve 12 by the temperature sensor signal on the preheating cylinder.
On said the first flash tank 1 and the second flash tank 6 leakage fluid dram pipelines stop valve in parallel with drain valve is housed respectively, when normally using, stop valve is closed.
Said condensate pipe 9 is condensed water or the remaining vapour of the equipment such as other preheating cylinders of production line.
Operating position of the present utility model is, waste water or the exhaust steam of draining by after Corrugator roller or the pressure roll heating in the condensate pipe 9, but its temperature is still higher, at first close the first stop valve 10, condensate pipe 9 is transported to high-temperature water or steam in the first flash tank 1 through pipeline, and in the first flash tank 1 is transported to respectively four preheating cylinders (the first flash tank 1 interior part condensed water is drained through condensate pipe 9 by the below drain valve), thereby to preheating cylinder 2,3,4,5 heat, water in being transported to preheating cylinder or vapor (steam) temperature do not reach when requiring, the PLC controller is controlled the aperture of electric control valve 12 by the temperature sensor signal in the preheating cylinder, electric control valve 12 is opened certain aperture, in four preheating cylinders, carry fresh high-temperature steam, improve the temperature of preheating cylinder, water after preheating cylinder uses or steam are in pipeline is discharged to the second flash tank 6, afterheat steam (partial condensation water) after the second flash tank 6 utilizes secondary is transported to the carton drying room, or Office Area, carton is dried or is the Office Area heating, when when not required, open the stop valve on the pipeline between the second flash tank 6 and the condensate pipe 9, water or steam in the second flash tank 6 are drained through condensate pipe 9, when preheating cylinder does not need to heat, open the stop valve on the pipeline between the first flash tank 1 liquid outlet and the condensate pipe 9, water or steam are drained through condensate pipe 9.
High-temperature condensation water or the afterheat steam secondary of the utility model after with other preheating cylinder preheating wheel hot plate positions of production line utilizes, preheating cylinder is heated, having realized taking full advantage of of resource, reduced production cost, is the innovation on the corrugated board steam energy-saving device.
