A device for recycling condensed water of a textile printing and dyeing dryer and its application method

Abstract

The invention discloses a condensate water recycling device of a textile printing, dyeing and drying machine and a using method thereof. The condensate water recycling device comprises a drying machine, a condensate inlet pipe is communicated with the interior of the drying machine, a filter is connected to the end, away from the drying machine, of the condensate inlet pipe, a steam trap is mounted on the condensate inlet pipe, an inner pipe is communicated with the end, away from the condensate inlet pipe, of the filter, a casing pipe is in sealing connection with the outer walls of the two ends of the inner pipe, an interlayer is formed between the casing pipe and the inner pipe, a water storage tank is arranged on the side, away from the filter, of the casing pipe, a condensate box is arranged in the water storage tank, and a plurality of connection rods are fixedly connected with the upper side wall and the lower side wall of the condensate box. The condensate water recycling device has the advantages that the condensate water in the drying machine can be timely drained out, the drying efficiency of the drying machine is improved, the heat efficiency is improved, meanwhile, thecondensate water is utilized again, the resource consumption is reduced, the printing and dyeing cost is lowered, in addition, an alarming device is arranged, and shut-down repair can be conducted timely once the condensate water recycling device is out of order.

Description

technical field [0001] The invention relates to the technical field of condensed water recycling equipment, in particular to a device for recycling condensed water of a textile printing and dyeing dryer and a method for using the same. Background technique [0002] At present, in the printing and dyeing industry, almost all fabrics need to be dried and dehydrated by a dryer, which is conducive to obtaining full color and better color fastness, and is also conducive to the control of color difference between the left, middle and right, and the fabric is dry during drying. A large amount of condensed water will be generated in the flood drum during the dryer drying process. [0003] In the prior art, steam traps are generally used to discharge the condensed water directly into the drain. This method has the following disadvantages: [0004] 1. The steam pressure in the dryer changes greatly, sometimes even lower than 0.05MPa, the working efficiency of the steam trap is greatl...

AI Technical Summary

Problems solved by technology

[0004] 1. The steam pressure in the dryer changes greatly, sometimes even lower than 0.05MPa, the working efficiency of the steam trap is greatly reduced, and the condensed water in the dryer cannot be discharged, resulting in low efficiency of the dryer and low thermal efficiency;

[0005] 2. Condensed water has a certain amount of heat energy, and direct discharge causes waste of resources. In addition, in other printing and dyeing processes, water needs to be heated for use, which additionally consumes resources and increases the cost of printing and dyeing.
