一种综合处理定型机废气的系统及方法
摘要：
本发明涉及综合处理定型机废气的系统，包括过滤器、两级气气换热器、喷淋洗涤器、除雾器、湿式静电除尘器、光催化反应器、引风机、烟囱、油水分离器和凉水塔；定型机废气与过滤器进口相连接，过滤器出口与第一级气气换热器壳程进口相连接，第一级气气换热器壳程出口与第二级气气换热器壳程进口相连接，第二级气气换热器壳程出口与喷淋洗涤器进口相连接，喷淋洗涤器出口与除雾器进口相连接，除雾器出口与湿式静电除尘器进口相连接，湿式静电除尘器出口与第二级气气换热器管程进口相连接。本发明的有益效果是：1)满足多污染物高效控制需求；2)安全性、稳定性得到提升；3)利用废气余热实现“消白”同时提高VOCs去除效率。
摘要（英）：

The invention relates to a system for comprehensively treating waste gas of a setting machine. The system includes a filter, a two-stage gas-gas heat exchanger, a spray scrubber, a demister, a wet electrostatic precipitator, a photocatalytic reactor, an induced draft fan, a chimney, an oil-water separator and a water cooling tower; and the waste gas of the setting machine is connected to an inletof the filter, an outlet of the filter is connected to a shell-side inlet of a first-stage gas-gas heat exchanger, a shell-side outlet of the first-stage gas-gas heat exchanger is connected to a shell-side inlet of a second-stage gas-gas heat exchanger, a shell-side outlet of the second-stage gas-gas heat exchanger is connected to an inlet of the spray scrubber, an outlet of the spray scrubber isconnected to an inlet of the demister, an outlet of the demister is connected to an inlet of the wet electrostatic precipitator, and an outlet of the wet electrostatic precipitator is connected to a tube-side inlet of the second-stage gas-gas heat exchanger. The system has the following beneficial effects: 1) the demand for efficient control of multiple pollutants is met; 2) the safety and the stability are improved; and 3) ''de-whitening'' is realized by using waste heat of the waste gas while the removal efficiency of VOCs is improved.
