An overflow control system

Abstract

The invention discloses an overflow control system comprising an overflow machine, a heat exchanger, a thermodetector, a plurality of pneumatic valves, a plurality of check valves, a water pump, a pipeline, a high-temperature water tank, a medium-temperature water tank, a steam inlet, a tap water inlet and a control system, wherein the thermodetector is disposed on an entrance of the overflow machine; temperature changes of the heat exchanger are adjusted according to process requirements and test values; the heat exchanger is connected with the control system; and the medium-temperature water tank and the high-temperature water tank are respectively connected with the heat exchanger through the pneumatic valves and the pipeline. With the above method, the overflow control system has the advantages that utilization rate of thermal energy of the system is improved, heat pollution is reduced, service life of the device and the pipeline is prolonged during overflow process, maintenance cost is saved, production cost is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of overflow machine equipment, in particular to an overflow control system. Background technique [0002] In the textile manufacturing industry, overflow machines are used to dye cloth. Generally, the hot liquid in the overflow machines in the prior art will be directly discharged when the temperature is lowered, causing pollution. The drying cylinder of the drying room, which is also used in cloth production, needs to be supplemented with steam in time, and the steam in the drying cylinder is continuously discharged. The discharged steam is basically directly discharged or collected and utilized in a small amount, which is a waste of energy. In the prior art, it has not been seen that the steam discharged from the drying room is used to heat the water temperature in the overflow machine. [0003] Through long-term practice, it is found that the energy utilization of the overflow machine in the prior art belongs to e...

AI Technical Summary

Problems solved by technology

The heat exchange device in the overflow system is directly heated by steam, which may easily cause the local temperature of the heated medium to be too high, and the heating will be uneven, resulting in uneven coloring of the cloth and waste

Moreover, the steam and condensate discharge system of the overflow equipment in the prior art has not been planned and designed, and the operator can open it at will according to his own requirements, which not only causes the randomness of the process, but also increases the waste of steam
