一种可以降低酸再生尾气中酸含量、氧化铁粉含量的装置
摘要：
一种可以降低酸再生尾气中酸含量、氧化铁粉含量的装置，属于冷轧酸再生设备技术领域，用于降低冷轧酸再生启炉和出现紧急事故期间尾气中酸含量、氧化铁粉含量，其技术方案是：它包括酸水存储罐、喷水泵、自循环泵、新酸泵、酸浓度分析仪和液位计，喷水泵安装在洗涤塔和吸收塔之间的连接管路中，酸水存储罐通过管路分别与吸收塔和再生酸罐相连接，在该管路中安装有自循环泵，新酸泵安装在酸水存储罐的新酸液输入管路中，酸浓度分析仪安装在酸水存储罐的输出管路中，液位计安装在酸水存储罐中。本实用新型可以保证洗涤塔、吸收塔的吸收效果，使酸再生尾气中酸含量、氧化铁粉含量降低，处于正常范围，有效地减少对设备的腐蚀和损坏。
摘要（英）：

The utility model discloses a device capable of reducing the content of acid and iron oxide powder in acid regeneration tail gas, belonging to the technical field of cold-rolling acid regeneration equipment. The device is used for reducing the content of acid and iron oxide powder in the tail gas during cold-rolling acid regeneration furnace starting and an emergency accident. The device comprises an acid water storage tank, a water spray pump, a self-circulation pump, a new acid pump, an acid concentration analyzer and a liquid level meter, wherein the water spray pump is mounted in a connection pipeline between a washing tower and an absorption tower; the acid water storage tank is connected with the absorption tower and a regenerated acid tank through a pipeline respectively; the self-circulation pump is mounted in the pipeline; the new acid pump is mounted in a new acid liquid input pipeline of the acid water storage tank; the acid concentration analyzer is mounted in an output pipeline of the acid water storage tank; and the liquid level meter is mounted in the acid water storage tank. The device disclosed by the utility model can ensure the absorption effect of the washing tower and the absorption tower, reduces the content of acid and iron oxide powder in the acid regeneration tail gas to a normal range, and effectively reduces corrosion and damage to the equipment.
