With domestic international market and technology big environment of changes, as China traditional industry of pig production of job way and profit way are requirements related industry for resources integration, to quality security for premise, regulation based farming, and management cost and the production, and sales cost, go standardization, and scale, and intensive, and market road, fast upgrade whole industry chain of regulation capacity, market competition capacity and anti-risk capacity. First, industry analysis (a) the basic situation in China is a traditional hog production and consumption country, 2008 46.15 million tons of pork, pig stock 462.64 million head by the end pig slaughter 609.6 million. National pig industry's annual production value at around 650 billion yuan, nearly 50% per cent of annual output value of animal husbandry. Sichuan province in 2008 produced 6.52 million tons of pork, with 694,000 tons of Chengdu city, live pig sell 10.46 million, first 15 Vice-provincial cities in the country. The whole nation advantage regional planning (2008-2015) there are 437 counties (cities), 55, Sichuan, Chengdu has 7 (including in pengzhou). International pig industry mainly include the European Union, the United States, and Canada, and Brazil and other absolute scale of animal husbandry industry and technology developed countries. Market 1, the domestic market from China's meat consumption habits and economic analysis of the development situation, the emergence of new trends in the market of domestic pork and its products. Docking is a pig production and sales more closely. The Yangtze River Delta, Pearl River Delta and the Bohai rim economic developed area industrial structure adjustment gathered pace, two or three industries to the Central and Western bias. Second, the rigid domestic consumption growth. For a long period, pork is still the largest variety of meat consumption in China, the absolute consumption continues to grow. Especially in the vast rural market growth potential. Third, market for pork and higher product quality requirements. Pollution-free pork safety and health has shown a very good market prospects. Four is the market changing. Currently, cold meat, more and more varieties of meat and pork meat products, which accounted for a large proportion of pork consumption, stores, chain stores, supermarkets and other marketing methods is on the rise, and transport has been extended to more than 2000 km in RADIUS. Chengdu is an important "River pig" resource market, the city's commercial rate reaches above 60% of live pigs, pork and raw materials primary processing products in the domestic and international reputation is high. Western hog trading center in Chengdu and provides disease-free areas of construction in order to further accelerate the development of swine industry realizes space and conditions. 2, the international markets at present, annual volume of trade in live pigs in the world year around 18 million, about 6 million tons of pork trade. A large net exporter of pork is mainly the EU and North America,-importing countries mainly in Asia, Japan, and Korea, and Singapore, the Philippines, Hong Kong and other countries and regions, as well as Russia, about 3 million tonnes were imported. It is predicted that the world meat consumption increase of 80% in Asia in the future, our country has obvious geographical advantages, export potential. With the advancement of live pigs superiority industry belt construction, animal disease .驻马店市安装股份有限公司 碱回收车间施工方案河南内乡仙鹤纸业集团有限公司220T/D碱回收车间安装工程施工方案驻马店市安装股份有限公司二00七年九月二十日 目 录1、前言3 2、工程概况5 3、100T/D碱炉施工方案5

108碱回收车间施工组织设计一、前言蒸发工段是造纸厂治污工程碱回收车间所属三个工段中的首前工段,它的主要任务是把蒸煮后的废稀黑碱液经过本工段的多效蒸发器,并利用较短的时间生产出可送燃烧工段浓度为43-45%的浓黑液,所以燃烧工段能否得到合格的浓黑液关键在于蒸发工段对稀黑液的蒸发质量和浓度指标。碱回收锅炉是现代碱回收装置的最主要设备之一。黑液锅炉的安全问题是至关重要的,碱炉的炉膛是由膜式水冷壁构成的,若任何一点疏忽都会造成水冷壁泄漏和爆管。从而发生熔融物遇水爆炸事故给工厂带来巨大损失，造成人员伤亡，设备严重损坏。其后果远比一般中、高压锅炉水冷壁爆管严重得多。因此，除制造厂在设计和制造上采取一系列的可靠的结构和制造工艺外（一般按高压锅炉的标准），安装工作也是锅炉建设过程中重要的环节，对锅炉的安全、经济和可靠运行极为重要。苛化工段是造纸厂治污工程碱回收车间所属三个工段中的最后一个工段，它的主要任务是把燃烧工段送来的绿液与稀白液混合澄清后，经苛化制成烧碱（即白液），送蒸煮工段使用。为了确保碱回收车间的安装质量和工作顺利进行,我公司认真研究了碱回收车间的设备和工艺要求,根据有关技术资料编写了碱回收车间的安装施工组织设计,供现场施工人员和质量人员参考使用,编写过程中,我们所依据的技术资料和所遵守的法规如下:1招标方技术交底；2.武汉锅炉集团所设计的图纸；3.设计院设计的图纸及说明;4.蒸汽锅炉安全技术监察规程,劳程发1996276号;5.DL/T507495电建规(锅炉机组篇);6.DL500792电建规(火力电厂焊接篇);7.DL503194电建规(管道篇);8.DL5881电建规(电厂化学篇);9.DL/T50961996电建规(钢制承压管道对接接头射线检验篇);10.DL/T504896电建规(管道焊缝接头超声波检验篇);11.GBJ235-82工业管道施工及验收规范;12.GBJ23682现场设备、工业管道焊接工程及验收规范;13.JB/T162093锅炉钢结构技术条件;14.JB161393锅炉受压元件焊接技术条件;15.JB1612XX锅炉水压试验技术条件;16.SDJ6682火力发电厂耐火材料技术条件验收方法;17.SDJ6885火力发电厂热力设备和管道保温材料技术条件与验收方法;18.轻工部首造纸工业碱回收安全技术规范ZB(6702289);19、有关碱回收炉、风压试验,筑炉保温及烘煮炉试运行按武汉锅炉集团碱回收炉产品说明书及现场条件制定方案执行；20、DLCS281电力建设施工与验收技术规范；21、ZBC6702289造纸工业碱回收炉安全技术规范；22、GB5025294工业安装工程质量检验评定统一标准；23、GB5027598压缩机、风机、泵安装工程施工验收规范；24、GB5023198机械设备安装工程施工及验收规范；25、DL/T507951电建规范（锅炉机组篇）；26、GB5023598

水冷壁的吊装水冷壁的组合场地在工艺开口下,吊点有两个设在顶部构架上,一个设在水冷壁的下部,顶部构架的吊点,一个设在水冷壁的上侧,一个设在水冷壁的2/3处,另外由16t吊车将水冷壁的下部托起,三个吊点互相配合将水冷壁吊装到位(详见水冷壁吊装示意图).水冷壁吊装示意图2.3.4 省煤器、空气予热器的吊装省煤器、空气予热器在组合完毕后,利用顶棚构架,可一次性到位.2.3.5 平台扶梯的安装平台扶梯设置在锅炉的四周,虽然重量轻,分布也较均匀,但安装时,起吊点要不停的转换,给安装带来一定的麻烦.为了方便安装,因此利用顶部构架在顶部位置一台可以摆臂的小桅杆,小桅杆上设置一台1t的电动葫芦。第三章 锅炉本体安装及技术要求3.1
