Problems solved by technology

The existing silk floss processing method needs to use various chemical reagents in the process of processing, and the chemical reagents remain on the silk floss after processing, which will affect the service life of the silk floss
[0003] Silk floss needs to be dried during the processing process. The method currently used is usually to place the silk floss that needs to be dried in a drying room, and to achieve the drying effect on the silk floss by passing hot air into the drying room. At present, it is When silk cotton provides hot air, it needs to connect hot air supply equipment, which consumes a lot of energy when providing hot air for the drying room
The drying of silk floss is to continuously inject steam into the silk floss drying room, and the baking process will not completely exhaust all the steam, the heat is not fully utilized in the discharge process, and there is a problem of waste

Abstract

The invention discloses a waste heat recovery system for silk floss processing, the waste heat recovery system is communicated with a heating system of a curing barn, the heating system is communicated with a boiler air supply system, and silk floss is placed in the curing barn to be dried; the waste heat system comprises a waste gas pipeline which is communicated with a heating system of the curing barn; the waste gas recovery device comprises a water storage tank and a gas inlet pipe, a water inlet and a water outlet are formed in the water storage tank, the water inlet is used for adding cold water, one end of the gas inlet pipe is communicated with the waste gas pipeline, the other end of the gas inlet pipe extends below the liquid level of the water storage tank, and liquid in the water storage tank is heated through gas of the gas inlet pipe; the scutching water supply pipe is communicated with a water outlet of the water storage tank, and hot water is discharged from the water outlet of the water storage tank. According to the waste heat recovery system, the productivity is saved, and the production cost is reduced. The prepared silk cotton has the advantages of being good in strength and filling power, good in gloss, free of peculiar smell, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of silkworm cocoon processing, in particular to a waste heat recovery system for silk wool processing and a silk wool processing method. Background technique [0002] The structure of mulberry silk is composed of two parts, silk fibroin and sericin. The molecular structure of silk fibroin is neatly arranged and the linear structure is better. The sericin component is located in the outer layer of mulberry silk, with a globular protein structure as the main component, the molecular chains are irregularly arranged, and the interaction force is small, and it is easy to dissolve and remove under high temperature and alkaline conditions. At present, mulberry silk is used for the preparation of silk garments on the one hand, and silk is processed on the other hand. In silk quilt processing, mulberry cocoons must be boiled, cocooned and opened in turn, and then the raw materials of silk wool required for silk quil...
