Solar dyeing machine system with function of gradient use of heat

Abstract

The invention discloses a solar dyeing machine system with a function of gradient use of heat. At present, waste water discharged in the production processes of desizing, scouring, dyeing and the like is at the temperature of more than 80 DEG C, direct discharging of the waste water causes energy waste, discharging the waste water into a waste water treatment tank makes all waste water to be at the temperature of more than 46 DEG C, and aerobic biochemical treatment is severely influenced. The solar dyeing machine system comprises a solar heating system, a waste heat recovery system, a high-temperature heat supply and compensation system, a dyeing machine system and a cooling system. The solar heating system form two-loop circulation, one loop is a water circulation loop formed by a plurality of serially connected solar vacuum tubes for heating water, a cold water pipeline and a hot water pipeline, and the other loop is an oil circulation loop formed by a plurality of serially connected solar vacuum tubes and an oil pipeline. The solar dyeing machine system has the advantages that temperature segmented recovery of heat is realized, the problem of surplus low-temperature heat in the existing waste heat recovery device is solved, and the solar dyeing machine system is applicable to various fiber dyeing processes and is more than 50% in comprehensive energy saving.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of solar energy and waste heat, in particular to a solar dyeing machine system for cascade utilization of heat energy. Background technique [0002] The printing and dyeing industry is a large energy consumer. During the printing and dyeing process, energy consumption such as electricity, coal, oil, and steam is high, accounting for more than 30% of the processing cost. The average comprehensive energy consumption per 10,000 yuan of output value is 0.86 tons of standard coal, compared with the average of 0.42 tons of standard coal in other industries. Coal more than doubled. Energy conservation and emission reduction has become a management goal of governments at all levels and industries. In the 2010 revision of the "Printing and Dyeing Industry Access Conditions", the assessment requirements for resource consumption: new or expanded printing and dyeing projects, the comprehensive energy...
