Description
【Technical field】
It the utility model is related to horizontal small duct type conduction oil wind technical field of heat exchange device, and in particular to Yi Zhongti
The high horizontal device for drawing wind-heat exchange efficiency.
【Background technology】
In OPP film production, the operation principle of cross directional stretch is to enter the sheet after the completion of longitudinal stretching laterally to draw
Stretch, it is necessary to be preheated to sheet in drawing process, stretching, sizing section three parts composition.Transverse Heated is hot air circulation system
System heating, by motor, blower fan, heat exchanger, bellows, a few part compositions of air cleaner.Cross directional stretch technique heating-up temperature
The central hot heating station that thermal source comes, is the erect-type heater with heat-insulating material, heating efficiency is；630,300Kcal/h, accurately
To 0.232MW, the limit of working temperature is 300 DEG C, and the heater inlet and outlet temperature difference is 25K, and sparking mode is divided into two-stage ignition operation.
The production temperature controlling range of production capacity horizontal drawing in the case of no lifting before this between 130~178 DEG C, heater
Temperature is set as 272-278 DEG C, and for fuel oil oil pressure also and then toward up-regulation, heating station is also to operate at full capacity, horizontal drawing heat exchanger
Magnetic valve open degree is 100%.But the lifting of customer demand therewith, do not turn off again and send the remarkable product of performance, such as crystal film,
The products such as wear-resistant membrane, high speed film.Because the horizontal drawing process temperature required for developing new product is different, required heat energy constantly carries
Rise, particularly horizontal drawing preheating section, 280 DEG C of the temperature highest setting temperature that current heating station is supplied can not meet current
Production requirement.And heating station limiting value is 300 DEG C, is special equipment again.Long-term work is pacified in critical safety temperature to boiler
There is great risk entirely, take and still do not reach manufacturing technique requirent to all conveying hot oil pipelines and valve envelope adiabatic cotton, temperature,
Can only reduction of speed production, considerable influence is produced to production capacity and delivery cycle.
Airduct tuyere is from being 180mm with a distance from diaphragm at the top and bottom of existing horizontal drawing airduct.Due to equipment in order to ensure
Heating effect, the conduction oil after boiler heats typically is furnished with one by heat exchanger, each heat exchanger using oil pump
Motor-driven valve, the size control of electronic valve opening passes through the deep fat amount of heat exchanger, then is entered by high velocity air by heat exchanger
Row heat exchange is heated to reach technique initialization temperature to air, and because technique initialization temperature is higher, electronic valve opening is essentially
100%, this is, meets that technological temperature can only be by heightening into oil temperature, up to 280 DEG C, but the temperature of oil oven is set to
280 DEG C, oil oven two-stage ignition can not stop, and be the limiting value of existing oil oven work, have uncertainty to the work safety of oil oven
And harmfulness.If exchange temperature can not reach production technology temperature, rupture of membranes will be produced, outward appearance, modulus of elasticity, anti-tensile is strong
The a series of quality problems such as degree, break-draw, turbidity, glossiness, thermal contraction, thickness produce, and cause defective defective product
Produce.For production line production capacity with packaging corresponding boiler plant, Maximum Power Output has been fixed, then is improved
The output temperature of conduction oil is infeasible for special equipment, and this causes equipment fluctuation of service even equipment safety thing
Therefore through analysing in depth, it is contemplated that improving air to the heat transfer efficiency of diaphragm and the heating power of raising heat exchanger.
