Description
Technical field
The present invention relates to a kind of steaminess drying cylinder fabric drying control method and device, belong to weave dyeing and finishing technique and equipment
Technical field.
Background technique
For textile printing and dyeing enterprises using steam baking tube drying plant heating drying band water fabric, steam baking tube drying plant is usual
One column drying unit is formed by least eight steam baking tube, is generally made using drying unit more than a column come drying band water fabric
Drying fabric meets technique requirement.
When steam baking tube drying plant works, each steam baking tube is by respective steam branch pipe by the steam in main steam range
It introduces and heats steam baking tube in steam baking tube, meanwhile, the steam of certain pressure can push steam baking tube and fabric heat exchange and shape
At condensed water discharged through siphon pipe, drain pipe, drain valve, collector pipe, achieve the purpose that in time it is hydrophobic.In time it is hydrophobic can
To improve steam baking tube heating efficiency, steam consumption is reduced, reduces production operation costs；In addition, hydrophobic in time can prevent
Condensed water in steam baking tube forms water hammer to reduce the abrasion of tube wall, valve and connector, can also prevent steam baking tube
Self weight increases, and when rotating at high speed, avoids security risk.
Currently, the fabric drying control of each column drying unit is to install steam controlled ratio additional in the column main steam range to adjust
Valve is detected according to drying end moisture content of fabric, is implemented PID to the controlled ratio control valve opening of main steam range and is adjusted control.
Calender drying is one big inertia time lag system, implements the differential forward controlling party of PID control and routine using ratio adjusting valve
Method effect is very unsatisfactory: on the one hand, be not able to satisfy the requirement of different temperatures deviation and deviation variation rate, dynamically control it is unstable,
Moisture content of fabric fluctuation is big；Stable state control deviation is big, and it is long to control to adjust the time.Moreover, when controlled ratio regulating valve is in middle or small
It is too small into the steam pressure in steam baking tube when aperture state, be much not enough to push condensed water by the road from drain valve to
Outer discharge, the serious ponding in steam baking tube inner cavity bring multiple drawbacks:
1. more condensed water accumulates, steam baking tube obviously shows that dynamic balancing is unbalance, and fabric creases easily on steam baking tube, out
Existing large area defective cloth, seriously affects rear road arranging process and is normally carried out；
2. the serious ponding in steam baking tube inner cavity greatly reduces heat exchange area, the attainable production technology temperature of steam baking tube
Decline, causes speed of production slow, production efficiency is low, while influencing product quality；
3. more condensed water accumulates, the abrasion of water hammer aggravation tube wall, valve and connector is formed, maintenance workload is big, expense
It is high；The self weight of steam baking tube increases, and generates security risk when rotated；
On the other hand, in continuous production Replacement procedure, calender drying time lag system, PID adjusting control response lead to drying slowly
Fabric does not meet technique requirement, and drying cropping quality cannot be guaranteed, and influences production capacity promotion.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, providing a kind of can reliably guarantee steam baking tube
Into vapor pressure and in time it is hydrophobic, reduce steam consumption, improve dry efficiency, prevent steam baking tube self weight increase, it is ensured that dry
Dry fabric meets the steaminess drying cylinder fabric drying control method of technique requirement.Meanwhile the present invention also provides a kind of using above-mentioned
The steaminess drying cylinder fabric drying control device of method.
In order to solve the above technical problems, the present invention uses such a steaminess drying cylinder fabric drying control method, it is described
Steaminess drying cylinder includes at least eight steam baking tube, and each steam baking tube is by respective steam branch pipe by the steam in main steam range
