彩涂线油漆固化炉的安全加热方法

巴中彩涂板生产线上涂上液体涂料后,溶剂在固化炉中被加热蒸发,钢带加热到预定温度,使涂层固化。这个过程消耗大量的能量。目前,为了达到环保标准,国内彩涂板生产线通常会对炉内废气进行排放

巴中彩涂板生产线废气加热至裂解点温度(733°C)热解焚烧,经烟道、排风机、烟囱排入大气,达标排放。此时,大气中产生大量的热能和温室气体,不仅污染环境,而且不能充分利用能源。因此,有些企业位于热解点以上的高温区,废气中含有有毒气体的溶剂大多被裂解、燃烧、裂解,释放出大量热能,消耗废气中的大部分氧气,产生高温惰性(将过量氧含量控制在5~8%左右,相对惰性)烟气,形成高温、 巴中彩涂板生产线低氧烟气,通过换热器加热新鲜空气,并将加热后的空气通过鼓风机送入硫化炉,固化干燥涂漆钢带。如申请日为2008年6月6日,公开日为第8个月“彩涂线有害气体集中焚烧余热利用”。根据防爆理论,确定了固化炉内发生爆炸的条件主要有三点,即温度、溶剂浓度和氧含量。在本方案中,硫化炉内的热风为热风,氧含量为21%。因此,为防止硫化炉内气体爆炸,应控制炉内溶剂浓度。富溶剂炉内气体的提取应采用大功率风机,这样风机功率大,能耗大。经过热交换后,空气供给硫化炉和生产线上其他需要热源的地方。焚烧尾气的排放会带走大量热量,需要固定在化学炉的供热风口,生产线的其他部位需要热源,以增加内燃机补充换热后的热风温度不足,这不仅增加了内燃机,还需要消耗大量的汽油。

After the liquid paint is applied on the color coated plate production line, the solvent is heated and evaporated by the heat in the curing furnace, and the strip is heated to a predetermined temperature to solidify the coating. This process consumes a lot of energy. At present, in order to meet the environmental protection standard, the domestic color coated plate production line usually exhausts the exhaust gas from the furnace

The waste gas is heated to the temperature of cracking point (733 ° C) for pyrolysis and incineration, and then discharged into the atmosphere through flue, exhaust fan and chimney to achieve standard emission. At this time, a large amount of heat energy and greenhouse gas are generated in the atmosphere, which not only pollutes the environment, but also can not make full use of energy. Therefore, some enterprises are located in the high temperature zone above the pyrolysis point Most of the solvents containing toxic gases in the waste gas are cracked, burned and cracked, which releases a large amount of heat energy and consumes most of the oxygen in the waste gas, resulting in high temperature inert (control the excess oxygen content to about 5-8%, relatively inert) flue gas, forming high-temperature and low oxygen flue gas, passing through the heat exchanger Heat the fresh air and send the heated air into the curing furnace through the blower to solidify and dry the painted steel strip. For example, the application date is June 6, 2008, and the publication date is Io month 8, "waste heat utilization of concentrated incineration of harmful gases in color coating line". According to the explosion-proof theory, the conditions required for explosion in the curing furnace are determined There are three main points, namely temperature, solvent concentration and oxygen content. In this scheme, the hot air supplied in the curing furnace is hot air, and the oxygen content is 21%. Therefore, in order to prevent the gas explosion in the curing furnace, the concentration of solvent in the furnace should be controlled. High power fan should be used to extract the gas in the solvent rich furnace to a large extent, In this way, the fan power is large and the energy consumption is large. After heat exchange, the air is supplied to the curing furnace and other places in the production line that need heat source. The emission of incineration tail gas will take away a large amount of heat, which needs to be fixed in the The heat supply tuyere of chemical furnace and other positions of production line need heat source to increase the shortage of hot air temperature after supplementary heat exchange of combustion engine, which not only increases the combustion engine, but also needs to consume a lot of gas.
