Electronic jet drying cylinder dryer

Abstract

The invention discloses a textile printing and dyeing electronic jet drying cylinder dryer and a jet drying cylinder, waste gas heat recovery and condensate water recovery thereof and a method for setting a moisture regain reference roller. The electronic jet drying cylinder dryer consists of a heat insulating and preserving drying room, the jet drying cylinder, a heat recovery and jet system and an electronic information system, wherein exhaust air is divided into exhausted air and circulating air according to humidity of the exhaust air; heat of the exhausted air is recovered by fresh air; the fresh air is mixed with the circulating air; the heat of condensate water is then recovered and the condensate water is sprayed to a textile; heating is performed and drying conditions are improved; complete on-line detection and control are performed on temperature, tension and moisture regain of the textile and humidity, temperature and speed of an air flow; therefore, heat application efficiency and drying efficiency are increased, production cost is reduced and production requirement of high-grade textiles is met in a scientific, strict, careful and reliable drying mode. The electronic jet drying cylinder dryer can be used for substituting a drying cylinder dryer or is made by modifying the drying cylinder dryer; a waste gas heat recovery system and a condensate water recovery system are suitable for various heating production occasions; and by the method for setting the moisture regain reference roller, reliability and validity of moisture regain control are solved.

Description

technical field [0001] The invention relates to a heating and drying equipment used in the fields of fabric dyeing, printing, processing, finishing and sizing, in particular to an electronic air-jet dryer and its air-jet dryer, waste gas heat recovery system, and condensed water recovery system And the setting method of the moisture regain reference roller. Background technique [0002] In the field of dyeing, printing, treating, finishing and sizing of fabrics (the term "fabric" is understood to include warp or ply), hot air dryers (the term "hot air dryer" is understood to include heat setting machines Or baking machine), drum dryer (the term "drum dryer" should be understood to include the drum drying unit in the combined machine) is a common drying equipment for fabric wet treatment process. The hot air dryer adopts the hot air convection heating method, and the heat utilization efficiency is relatively low. .-2 edition.-Beijing: China Textile Press, 2010.5) records, u...
