沼氣的脫硫的建設(shè)流程是怎樣的，涉及哪些步驟？其實(shí)主要包括七個(gè)步驟，很多人都不清楚。在本文中，我們將介紹一步開(kāi)始:測(cè)量和放樣。
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.
沼氣工程脫硫的具體過(guò)程包括:測(cè)量放樣-鼓壁碾壓-一次防腐-鼓接頭組裝-塔底組裝-塔體組裝-整體防腐。
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.
測(cè)量放樣步驟介紹:
Introduction to survey and setting out steps:
1.所選用的材料和附件應(yīng)具有質(zhì)量證書(shū)，并符合現(xiàn)行規(guī)定。鋼板和附件應(yīng)有清晰的產(chǎn)品標(biāo)識(shí)。檢查是否符合設(shè)計(jì)要求。鋼板應(yīng)逐個(gè)進(jìn)行外觀(guān)檢查，其質(zhì)量應(yīng)符合現(xiàn)行的鋼板質(zhì)量標(biāo)準(zhǔn)規(guī)定。鋼板的局部減薄量、劃痕深度和實(shí)際負(fù)偏差之和不應(yīng)大于相應(yīng)鋼板的標(biāo)準(zhǔn)負(fù)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.根據(jù)規(guī)格對(duì)材料的外觀(guān)質(zhì)量和尺寸進(jìn)行抽查，如發(fā)現(xiàn)不合格產(chǎn)品，加倍抽查。如果復(fù)檢不合格，通知供應(yīng)商退貨。
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.焊接材料(焊條)的選擇應(yīng)符合設(shè)計(jì)要求并有質(zhì)量證明書(shū)，質(zhì)量證明書(shū)應(yīng)符合現(xiàn)行質(zhì)量標(biāo)準(zhǔn)《碳鋼焊條》GB/T5117的要求。
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.鋼板尺寸檢驗(yàn):長(zhǎng)寬允許偏差1.5m對(duì)角線(xiàn)之間的允許偏差為3毫米；板材兩側(cè)直線(xiàn)度允許偏差為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.
