Vapor drying cylinder siphon pipe damage online detecting method

Abstract

The invention discloses a vapor drying cylinder siphon pipe damage online detecting method. The method includes the steps of a, setting three data storage units in a data storage area of an electric controller; b, collecting temperature sensor data through the electric controller at the interval of T seconds, calculating the average value, and storing the average value in a D(pre) data storage unit; c, continuing to collect temperature sensor data through the electric controller at the interval of T seconds, calculating the average value of the continuously-collected data, and storing the average value into a D(cur) data storage unit; d, comparing the value stored in the D(cur) data storage unit with the value stored in the D(pre) data storage unit; e, judging the accumulated value storedin a P(cou) data storage unit through the electric controller. The siphon pipe damage can be found in time and workers are reminded to instantly replace a damaged siphon pipe, it is effectively avoided that condensate water cannot be discharged, vapor consumption is reduced, drying efficiency is improved, and various accidents are avoided.

Description

technical field [0001] The invention relates to a method for detecting the safety performance of internal parts of a steam drying cylinder, in particular to an on-line detection method for the damage of a siphon tube used in a steam drying cylinder, and belongs to the technical field of textile dyeing and finishing processes. Background technique [0002] Textile printing and dyeing enterprises use steam drums to heat and dry fabrics with water, and the condensed water in the steam drums affects the heat exchange efficiency. It is necessary to discharge the condensed water through the siphon in time to improve the thermal efficiency of the steam drum drying equipment, thereby saving steam consumption. , Reduce energy consumption. [0003] The siphon tube installed in the inner cavity of the steam dryer is usually made of metal. Under working conditions and long-term use, it will undergo chemical or electrochemical reactions with condensed water and cause corrosion or even da...

AI Technical Summary

Problems solved by technology

When the siphon tube is damaged, the condensed water cannot be discharged, which will cause the condensed water to accumulate in the steam dryer to form water hammer, which will aggravate the wear of the pipe wall, valves and joints, increase maintenance costs and downtime, and accumulate condensed water in the steam dryer Finally, it will increase the weight of the steam drying cylinder, which will cause safety hazards when rotating at high speed; and the condensed water will not be discharged, which will seriously affect the heat exchange effect of the steam drying cylinder, increase the drying time of the fabric, and will lead to large steam consumption and poor energy efficiency. , Increased operati
