Abstract
The invention relates to the field of the utilization and recycling of waste heat in a printing and dyeing process, in particular to a method for using and recycling technical waste heat in the printing and dyeing process by using double hot water systems. The method comprises the following steps of: recycling the waste heat by using two sets of hot water systems; (1) storing condensed water generated from heat exchange of boiler steam and a dyeing machine and condensed water condensed by steam generated from the heat exchange of normal-temperature water and the dyeing machine into a first reservoir; storing cooling water generated from the heat exchange of the normal-temperature water and the dyeing machine into a second reservoir; (2) supplying the condensed water in the first reservoir to a yarn boiling and soaping process of a dying machine and to boilers at the same time; and (3) supplying the cooling water in the second reservoir to heating equipment, bathing, material melting chambers or colored spinning cake machines and to the dying machine at the same time. Compared with the prior art, the method controls the flow of water tanks at different temperatures according to different process requirements so as to reduce energy consumption to the maximum extent. Meanwhile, the method can improve work efficiency so as to improve unit capacity.
Description
Technical field
The present invention relates to UTILIZATION OF VESIDUAL HEAT IN and recovery field in the dyeing and printing process, be specifically related to a kind of method that adopts two hot-water heating system utilizations and recovery technology waste heat at dyeing and printing process.
Background technology
China is a weaving big country, textile industry occupies critical role in national economy, textile product is one of main exit product, equally, printing and dyeing to textiles also are huge industry groups, in dyeing process, can produce a large amount of waste heats, but all take the mode of in line and simple utilization aspect the processing of the cooling water of at present common dye-works after absorbing waste heat, can not guarantee effective utilization of the energy fully, caused a large amount of wastes of the energy, in current construction amphitypy society under the new situation, worked out more energy-efficient UTILIZATION OF VESIDUAL HEAT IN and recovery method and be very important.
Summary of the invention
For overcoming existing recovery and utilizing the above-mentioned shortcoming of technology waste heat method, the invention provides and utilize two hot-water heating systems in dyeing and printing process, to reclaim and utilize the method for technology waste heat, this method has advantages such as energy savings, operating efficiency height, and this method may further comprise the steps:
Utilize two cover hot-water heating system recycle and recovery,
(1) will all be stored in first tank by the condensed condensed water of water vapour that produces after the condensed water that produces after Boiler Steam and the dyeing machine heat exchange and normal-temperature water and the dyeing machine heat exchange; To be stored in second tank by the cooling water that produces after normal-temperature water and the dyeing machine heat exchange;
The condensed water of (2) first tanks is supplied with dyeing machine and is boiled yarn and soap technology, supplies with boiler simultaneously and uses;
The cooling water of (3) second tanks is supplied with heating system, bathing, change material room or look and is spun pancake making machine, also supplies with dyeing machine simultaneously and uses.
The water temperature of first tank preferably keeps 80 ℃ of constant temperature.
The water temperature of second tank preferably keeps 50 ℃ of constant temperature.
Method of the present invention is the optimization improvement to technology UTILIZATION OF VESIDUAL HEAT IN in the dyeing and printing process and recovery method.
The present invention compared with prior art has following advantage and beneficial effect:
1, existing hot water heat-exchange network flow process that the present invention is perfect has been optimized the recovery of system capacity, has reduced the cooling and the heating load of relevant apparatus.
2, the present invention has improved existing hot water energy and has utilized flow process, has optimized the utilization of hot water energy.
3, the present invention controls the water tank flow of different temperatures according to the difference of process requirements, to reduce the consumption of the energy to greatest extent.On the one hand, the cooling water that produces by heat exchanger enters 50 ℃ of sealing tanks, and this section cooling water can be supplied with heating system, workman's bathing, change material room and look and spin pancake making machine; Supplying with dyeing machine on the other hand uses.The condensed water that produces by heat exchanger enters 80 ℃ of sealing tanks, and this section condensed water can be used to boil yarn and the technology of soaping for dyeing machine, makes on average to boil the yarn time and be reduced to 10 hours by 14 hours, cleans by high temperature reduction, and the fabric soaping fastness is better faster; Can supply with simultaneously boiler and use, accelerate the stove water heating-up time, play the effect of energy efficient.Through the present invention, the energy can be minimized in the past, and water saves 33%, and steam saves 30%, and electricity saves 30%, and sewage saves 33%.Simultaneously, operating efficiency is improved, thereby the unit production capacity also increases.
