Description
技术领域：Technical field:
本实用新型涉及一种加热系统，尤其涉及一种导热油的加热系统。The utility model relates to a heating system, in particular to a heating system for heat conduction oil.
背景技术：Background technique:
1-氨基-8-萘酚-3,6-二磺酸单钠盐生产工序为：磺化-硝化-脱硝-中和-还原-还原压滤-酸析-吸滤-溶解-配置-碱熔-二酸析-抽滤-打浆-膜压-闪蒸。上述生产过程中存在以下问题：1、在碱熔和闪蒸工序中，需要使用180-220℃的热源对反应产物进行加热，因导热油具有抗热裂化和化学氧化的性能，传热效率好，散热快，热稳定性很好，因此被广泛用于碱熔釜和闪蒸设备的加热，为了使导热油的温度满足使用的温度要求，需要单独设置热油炉对低温导热油进行加热，热油炉能源损耗高；2、反应中产生的高盐废水需要送入喷雾干燥器中，利用400℃的热风对高盐废水进行浓缩处理，热风由热风炉提供，但是，热风炉产生的热风温度基本在400-500℃左右，需要降温后才能使用，目前采用空气与导热油换热降温，换热后的空气直接排放，造成能源的浪费。The production process of 1-amino-8-naphthol-3,6-disulfonic acid monosodium salt is: sulfonation-nitration-denitration-neutralization-reduction-reduction pressure filtration-acid analysis-suction filtration-dissolution-configuration-alkali Melting - diacid analysis - suction filtration - beating - membrane pressure - flash evaporation. The following problems exist in the above production process: 1. In the alkali fusion and flash evaporation process, it is necessary to use a heat source at 180-220°C to heat the reaction product. Because the heat transfer oil has the performance of resisting thermal cracking and chemical oxidation, the heat transfer efficiency is good , fast heat dissipation and good thermal stability, so it is widely used in the heating of alkali melting kettles and flash evaporation equipment. In order to make the temperature of the heat transfer oil meet the temperature requirements of use, it is necessary to set up a separate hot oil furnace to heat the low temperature heat transfer oil. The energy consumption of the hot oil furnace is high; 2. The high-salt wastewater generated in the reaction needs to be sent to the spray dryer, and the high-salt wastewater is concentrated with 400°C hot air. The hot air is provided by the hot air stove, but the hot air generated by the hot air stove The temperature is basically around 400-500°C, and it needs to be cooled before it can be used. At present, air and heat transfer oil are used to exchange heat for cooling, and the air after heat exchange is directly discharged, resulting in waste of energy.
