Description

Preventing moisture condensation of roof of textile workshop method and device thereof
One, technical field:
The present invention relates to spinning factory ventilation field, particularly a kind of preventing moisture condensation of roof of textile workshop method and device thereof.
Two, background technology:
Textile production process has strict demand to humiture, need keep the higher temperature and humidity conditions in workshop, weaving produce each main technique to temperature, relative humidity require as shown in the table:
Spinning and weaving workshop general requirements temperature is 21 ℃-26 ℃ in the winter time, humidity is 60%-75%, and is with respect to outdoor arctic weather temperature and lower humidity, dry and cold at the north of china in winter air especially, keep hot and humid like this production environment in the workshop, be easy to occur roof dewfall phenomenon.The roof dewfall is meant that the phenomenon of condensed water appears near being lower than during the air dew point temperature in house ceiling internal surface temperature on the roof soffit.The condensed water of dewfall is assembled and is occurred dripping, cause the interior humidity of factory building excessive, and then can make weaving fiber tenderness occur in producing, easily interrupted, short flannel increases, lap is fluffy, the problem that the noil flyings increase affects to technology, product quality and output.The increasing of humidity also can cause damage to textile machine and various components and parts, influences the normal operation and the application life of equipment, strengthens cost of production; Dewfall also makes the roof accelerated ageing, and heat insulating material does not have heat insulation effect.The globule that forms when the dewfall phenomenon is serious can irregularly drip, if furred ceiling is installed, the furred ceiling large tracts of land is moistening and drip, also can be dripped penetrates, and the globule splashes into production line and causes the stained of equipment and product, and indoor environment worsens, the problem that Yarn break, yarn defect, production technology change occur, have a strong impact on product quality, produce and be forced to interrupt, cause enormous economic loss.But also can the corrosion pipeline and power circuit, equipment, reduce the reliability of electric fixtures, safety in production is threatened.Spinning factory roof condensation trouble perplexs textile enterprise always, a professional difficult problem that has also become weaving to produce.Especially current, much textile enterprise is newly-built, extend a factory building and all adopt steel work to build factory building, steel-structure factory building has from heavy and light, industrial production cost is low, short construction period, anti-seismic performance is good, investment comprehensive advantages such as gain quick return, but steel-structure factory building is still short in the application time of textile enterprise, its heat-insulating property and sealing do not reach the requirement of textile technology sometimes, the design of factory building, construction, the application of new material is the not abundant checking through putting into practice also, particularly in northern China colder area in winter, some factory buildings are because some reason roof in winter dewfall has a strong impact on production, the roof of having to dismantle again, reinstall, give textile enterprise and design, unit in charge of construction all causes great economic loss, and solving spinning factory roof dewfall also becomes a difficult problem that presses for solution in the development of current textile enterprise.
Cause the reason of dewfall mainly to be temperature, the psychrometric difference that spinning factory indoor and outdoor in winter is bigger, near the dew point of the air temperature of roof soffit is lower than, factory building roof portion relative air humidity contains water vapour greatly.Concrete reason has many-side, roof building material layer heat preservation property is undesirable, factory building is provided with interior low, the high humidity of air themperature of furred ceiling layer of ceiling structure, roof insulation material layer inner surface is not done to handle every vapour, or lost efficacy every the vapour layer, building operations is lack of standardization, and adiabator layer exists weak part or space, " cold bridge " phenomenon occurs.
The traditional solution that prevents spinning factory roof dewfall at present is to lay water back near the factory building roof, logical high-temperature steam in the pipeline, and then improve near the air themperature in roof, improve the roof underlaying surface temperature, make it to be higher than the damp-heat air dewpoint temperature, thereby reach the purpose of eliminating dewfall.But this method implementation cost is big, the maintenance cost height, consume a large amount of steam, produce these steam a large amount of energy that will burn, as coal, oil plant, the fuel combustion boiler is discharged a large amount of carbon dioxide and dust, serious environment pollution, special today of emphasizing environmental protection at energy scarcity, country's Eleventh Five-Year Plan development outline and textile industry Eleventh Five-Year Plan outline, all the textile industry energy-saving and emission-reduction have been proposed strict requirement, formulated specific targets, this anti-condensation method is neither energy-conservation, more can not reduce discharging, also environment is polluted, cost is high especially, has fundamentally lagged far behind modern textile industrial expansion trend.
Solving factory building roof dewfall can also start with from the heat-insulating property that improves the roof, add heat insulating material to reduce the conduction heat, increase heat insulating material thickness on the roof, carry out in the construction, roof soffit spraying antifogging coating every the sealing of vapour layer, but fact proved, these methods can't prevent dewfall when temperature is low in the winter time, and increase the building costs of factory building greatly, have prolonged construction period, especially the factory building that has built up can only be overhauled or rebuild, cost is higher.The performance of ventilating that improves the roof also is a kind of way that prevents factory building roof dewfall, do the air draft of a few row's natural ventilator, or installation ridge type ventilation machine, or set up roof electric drive axle flow fan, the wet dewfall that prevents falls in ventilation, but these methods can only prevent the local dewfall in roof, very easily form the air-flow short circuit phenomenon on the roof, cause indoor heat to run off in a large number, cause the workshop temperature to reduce, destroy production environment in the workshop, influence product quality, not too suitable for the spinning factory that humiture is strict, and the equipment manufacturing cost costliness that has, energy consumption does not meet the developing direction of textile industry energy-saving and emission-reduction greatly.
