Assembled type desulfurization column body

Abstract

The invention relates to an assembled type desulfurization column body. 24-120 rectangular steel skeletons and 8-24 trapezoidal steel skeletons are connected and assembled into a steel skeleton body through fasteners; engineering plastic plates are fixed on the integral inner wall of the steel framework through the fasteners with sealing strip gaskets; and the rectangular steel skeleton and the trapezoidal steel skeleton are prefabricated and formed by angle steel. According to the assembled desulfurization column body, the product quality is ensured; the efficiency is improved (the quality and the performance are improved by 2-3 times); the cost is reduced (only 60% of the construction cost in a traditional mode), the construction period is shortened (only 20% of the construction period in the traditional mode), labor is saved (only 20% of the construction period in the traditional mode), the service life of a product is prolonged, and conditions are created for safe and civilized production.

Description

technical field [0001] The invention belongs to the technical field of purification towers, and is an assembled desulfurization tower body used for purifying dust removal, desulfurization, denitrification, demisting and other flue gas treatment aspects. Background technique [0002] At present, my country's air pollution control tasks are heavy, the pace is fast, and the standards are high. On July 1, 2014, the new GB13271-2014 "Boiler Air Pollutant Emission Standard" was implemented. While further tightening the emission limit standards, it also proposed a pollution control capability and effect in the field of environmental protection and air pollution control. No exam paper. On the one hand, there are a large number of flue gas dust removal, desulfurization, denitrification, demisting, purification towers, etc. for environmental protection and air pollution control, which require advanced matching equipment manufacturing. On the one hand, most of the existing purificatio...

Problems solved by technology

This traditional production method has rough craftsmanship, simple and backward technology, and the more dry it is, the more it works at high altitudes. In this way, the difficulty of construction and safety risks after dozens of days are conceivable, and quality problems and personal safety problems occur. It is unavoidable, especially after the completion of the steel structure main tower, it is even more difficult to make glass flakes for corrosion protection

To sum up, there are the following problems: one is the working environment factor, the expensive and delicate glass flake anti-corrosion will affect the curing quality when the ambient temperature is lower than 10 degrees and the construction is cloudy and rainy; the other is the construction difficulty factor, because the construction is difficult and the efficiency is low , long curing cycle and other factors lead to high cost; third, factors such as material performance and operation proficiency, the performance of glass flake resins on the market is uneven, the proportion of curing agent is difficult to strictly control, and the professional proficiency of many construction workers is difficult to order Uniform, due to the above uncertain factors, steel structures lined with glass flake anticorrosion generally fail to achieve the expected quality effect

One is that the site must have the conditions to install a complete set of large-scale FRP on-site winding molding machines; the other is that construction cannot be carried out on cloudy and rainy days, and it is difficult to cure when the ambient temperature is lower than 10 degrees. And poor corrosion resistance, low strength, no wear and high cost
