摘 要
从1949年美国研制出世界上第一套催化燃烧装置到现在,催化燃烧技术已广泛地应用于油漆、橡胶加工、塑料加工、树脂加工、皮革加工、食品业和铸造业等部门,也用于汽车废气净化等方面。中国在1973年开始将催化燃烧法用于治理漆包线烘干炉排出的有机废气,随后又在绝缘材料、印刷工业等方面进行了研究,使催化燃烧法得到了广泛的应用。催化燃烧反应是在催化燃烧设备中进行的,透平后待处理的低温尾气与催化燃烧处理后高温尾气在换热器中进行热量交换,待处理低温尾气升温后再经电加热器加热到320℃左右,加热后的尾气送入催化燃烧反应器,去除尾气中的有机组分。催化燃烧处理后高温尾气将热量传递给处理的低温尾气后,经尾气洗涤塔洗涤后由尾气洗涤塔放空烟囱排入大气。本技术报告的主要内容如下:
(1)介绍了催化燃烧反应,催化燃烧设备,为催化燃烧设备设计奠定基础。
(2)催化燃烧反应器、换热器的工艺计算,确定设备的工艺尺寸、工艺操作参数及全套施工图。
(3)进行催化燃烧反应器设计,通过已知的设计参数和参照《过程设备设计》、GB150-2011《钢制压力容器》标准等进行结构设计,强度计算并进行校核。
(4)板式换热器的设计计算,板式换热器的结构相对于板翅式换热器、壳管式换热器和列管式换热器比较简单。通过查阅换热器设计相关标准得出的数据,对换热器的进行设计,具体分为换热器的热工计算、结构计算和强度计算。参照《过程设备设计》、GB150-2011、GB151-1999,综合考虑各种因素,结构设计需要选择适用合理的结构形式,同时满足制造、检修、装配、等要求。

Abstract
From 1949 the United States developed the world's first catalytic combustion device to now, catalytic combustion technology has been widely used in paint, rubber processing, plastic processing, resin processing, leather processing, food industry and the casting industry and other sectors, but also for automobile exhaust gas purifying etc.. China started in 1973 for the catalytic combustion exhaust treatment enameled oven organic waste, followed by an insulating material, the printing industry and other aspects of the study, the catalytic combustion method has been widely used. Catalytic combustion in the catalytic combustion reaction is carried out in the device, the low temperature turbine exhaust gas to be treated with a catalytic combustion process, exhaust gas heat exchange in the heat exchanger, the low temperature exhaust gas to be treated after heating by the electric heater to 320 about ℃, after heating the exhaust gas fed to the catalytic combustion reactor to remove organic components in the exhaust gas. After the high-temperature exhaust gas catalytic combustion treatment will transfer heat to low exhaust after treatment, after washing scrubber exhaust vent from the exhaust scrubber chimney into the atmosphere. The main contents of this technical report are as follows:
(1) describes the reaction of catalytic combustion, catalytic combustion equipment, lay the foundation for the catalytic combustion equipment design.
(2) catalytic combustion reactor, heat exchanger technology calculations to determine the size of the process equipment, process operating parameters and a full set of construction drawings.
(3) catalytic combustion reactor design, structural design by a known design parameters and reference "Process Equipment Design", GB150-2011 "Steel Pressure Vessel" standards, strength calculation and check.
