Energy-saving yarn-singeing burner

Abstract

The invention relates to an energy-saving yarn-singeing burner. Structurally, a burning cover which is a reburning area is arranged on the upper part of the burning area of a flame tube; and a small door is arranged on the burning cover. Compared with the structure without the reburning area, the energy-saving yarn-singeing burner has the following advantages: under the conditions of the same mixed gas (i.e., flow and pressure are the same at the mixed gas inlet of an item I fire hole seat), the length of flame is increased, consequently, on the premise of achieving the same yarn-singeing effect, the yarn-winding speed can be increased, so that the singeing output can be increased and the consumption of liquefied petroleum gas can be saved. Since the small door is arranged on the burning cover, in the normal process of yarn singeing, after the small door is closed, the influence of wind on flame can be reduced in a workshop, so that the singeing effect can be more stable.

Description

Technical field [0001] The invention relates to a yarn singeing combustion device, in particular to an energy-saving yarn singeing combustion device. Background technique [0002] Singeing refers to the process of passing yarn or fabric quickly through a flame or rubbing it over a hot metal surface to burn off the fuzz on the surface. The fiber will produce a lot of fuzz on the surface of the yarn and fabric after textile processing, which will affect the process effect of dyeing and finishing; the function of singeing: to prevent certain defects in the post-processing process, such as dust contamination, dyeing roller, mercerizing liquid recovery Difficulty, poor gloss of the cloth surface, padding and knife dragging during printing, pilling, affecting the clarity of the pattern, etc. [0003] In the normal singeing process of the yarn, a combustion hood, that is, a reburning zone, is designed on the upper part of the burning zone of the combustion tube; (that is, the flo...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the inefficiency of the existing yarn singeing combustion device, the present invention provides an energy-saving yarn singeing combustion device. In the yarn singeing combustion device, a combustion cover is designed on the upper part of the combustion tube combustion area. That is, the reburning zone; the design of the combustion hood, that is, the reburning zone, compared with the structure without the reburning zone, under the same mixed gas condition (that is, the mixed gas inlet flow and pressure through the burner seat are the same), the length of the flame is increased , the length of the flame has been increased from about 60 mm to 75 mm. Under the premise of achieving the same yarn singeing effect, it can not only increase the winding speed of the yarn, improve the singeing efficiency, but also increase the singeing output and save liquefied petroleum Gas consumption, after calculation, the singeing efficiency is increased by about 25%, and the consumption of liquefied petroleum gas is reduced by about 20%.
