Research and development of construction process of internal components of boiler desulfurization tower

Abstract

The invention discloses research and development of a construction process of internal components of a boiler desulfurization tower, and relates to the technical field of boiler desulfurization towerinternal component construction processes. The research and development comprise the steps of raw material quality control, quality control before construction, welding quality control, absorption tower wallboard perpendicularity deviation control, an absorption tower internal component installation process, supporting beam installation, demister installation, spraying layer installation, turbulator installation, oxidation air pipeline installation and construction cost reduction. Raw materials and absorption tower materials are purchased by a general package unit, are organized and accepted by a supervisor after arriving at the site, and are submitted to be inspected, factory certificates and test reports of each batch of materials are inspected, and the materials needing to be re-inspected are sampled in time for inspection. The research and development of the construction process of the internal components of the boiler desulfurization tower have the advantages that the constructionof each part in the tower is divided, each construction procedure is optimized, the construction experience is provided for similar construction projects, the construction procedures are optimized, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of construction technology for internal components of a boiler desulfurization tower, in particular to the research and development of a construction technology for internal components of a boiler desulfurization tower. Background technique [0002] In China, the research and development of flue gas desulfurization technology began in the 1970s, about 40 years later than abroad, and successively carried out experiments such as sodium nitrite circulation method, iodine-containing activated carbon adsorption method, limestone-gypsum method, etc., entered the 80 Since the 1990s, the country's electric power sector has carried out research and development on flue gas desulfurization in thermal power plants. A relatively stable desulfurization technology has been established, such as ammonia desulfurization, calcium desulfurization, magnesium desulfurization, etc., and the desulfurization efficiency can reach 95%...

AI Technical Summary

Problems solved by technology

[0003] At present, desulfurization technology is widely used in thermal power plants to desulfurize and reduce air pollution. We have participated in many desulfurization equipment installation projects in the past one or two years, and have accumulated rich experience. However, the structural installation and materials inside the desulfurization tower During the installation process, due to the disconnection of construction procedures, etc., it caused a lot of waste. The installation requirements of desulfurization equipment are strict, and the fire protection requirements are an indispensable red line in the entire construction process. The on-site fire accident of the desulfurization tower caused great economic losses and adverse effects. The reason is that the internal construction is the direct cause of the fire, so the installation of the internal components of the absorption tower is a top priority for planning and arrangement. the most important link
