沼气的脱硫的建设流程是怎样的,涉及哪些步骤?其实主要包括七个步骤,很多人都不清楚。在本文中,大家将先容一步开始:测量和放样。
What is the construction process of biogas desulfurization and what steps are involved? In fact, it mainly includes seven steps, which many people are not clear about. In this article, we will introduce the first step: Survey and lofting.
沼气工程脱硫的具体过程包括:测量放样-鼓壁碾压-一次防腐-鼓接头组装-塔底组装-塔体组装-整体防腐。
The specific process of desulfurization in biogas project includes: Surveying and setting out drum wall rolling primary anti-corrosion drum joint assembly tower bottom assembly tower body assembly overall anti-corrosion.
测量放样步骤先容:
Introduction to survey and setting out steps:
1.所选用的材料和附件应具有质量证书,并符合现行规定。钢板和附件应有清晰的产品标识。检查是否符合设计要求。钢板应逐个进行外观检查,其质量应符合现行的钢板质量标准规定。钢板的局部减薄量、划痕深度和实际负偏差之和不应大于相应钢板的标准负偏差值。

1. The selected materials and accessories shall have quality certificates and comply with the current regulations. The steel plate and accessories shall have clear product identification. Check whether it meets the design requirements. The appearance of steel plates shall be inspected one by one, and the quality shall comply with the current steel plate quality standards. The sum of local thinning, scratch depth and actual negative deviation of steel plate shall not be greater than the standard negative deviation of corresponding steel plate.
2.根据规格对材料的外观质量和尺寸进行抽查,如发现不合格产品,加倍抽查。如果复检不合格,通知供应商退货。
2. Spot check the appearance quality and size of materials according to the specifications, and double the spot check if unqualified products are found. If the re inspection is not qualified, inform the supplier to return the goods.

3. The selection of welding materials (welding rods) shall meet the design requirements with quality certificate, and the quality certificate shall meet the requirements of the current quality standard carbon steel welding rod (GB / t5117).
4.钢板尺寸检验:长宽允许偏差1.5m对角线之间的允许偏差为3毫米;板材两侧直线度允许偏差为1m。
4. Steel plate size inspection: the allowable deviation of length and width is 1.5m, and the allowable deviation between diagonals is 3mm; The allowable deviation of straightness on both sides of the plate is 1m.
