Frame type enamel block corrosion-resistant chimney and mounting method thereof

Abstract

The invention provides a frame type enamel block corrosion-resistant chimney and a mounting method thereof so as to overcome the efficiencies in the prior art that a corrosion-resistant inner barrel of the industrial chimney is high in cost, tedious to construct, inconvenient to use and the like. The inner barrel of the corrosion-resistant chimney is assembled by enamel blocks which are locked with nut assemblies through bolts; a high-temperature-resistant sealing sheet is arranged between two adjacent enamel blocks, the gap between two adjacent enamel blocks is filled with an acid-resistant and high-temperature-resistant elastic sealant, so that the sealing property is good; the enamel blocks are welded to a steel frame through an arranged fixed plate, so that the enamel blocks are small in welding area and convenient to construct; and the enamel blocks are relatively small in self weight; the chimney is mounted in an inverse manner and can be mounted just by conventional hoisting equipment, so that the chimney is quite convenient to construct, and the cost of the enamel block is lower than that of a titanium steel composite board, and therefore, the cost of the chimney can be lowered.

Description

technical field [0001] The invention relates to a chimney, in particular to a frame type enamel board anti-corrosion chimney and an installation method thereof. Background technique [0002] Most of the industrial chimneys are composed of a frame and an inner cylinder. Because most of the gases discharged from the chimney are high-temperature and corrosive gases, the inner cylinder needs to be made of anti-corrosion materials. The existing anti-corrosion inner cylinder used in the chimney is generally welded by multiple titanium-steel clad plates. The titanium-steel clad plate has good high-temperature resistance and anti-corrosion performance, but the price of the titanium-steel clad plate is very high because it contains rare materials. The anti-corrosion inner cylinder made of titanium steel composite plate is very expensive, and the titanium steel composite plate is very heavy, so relatively large lifting equipment is required for installation, and the titanium steel com...

Problems solved by technology

The existing anti-corrosion inner cylinder used in the chimney is generally welded by multiple titanium-steel clad plates. The titanium-steel clad plate has good high-temperature resistance and anti-corrosion performance, but the price of the titanium-steel clad plate is very high because it contains rare materials. The anti-corrosion inner cylinder made of titanium steel composite plate is very expensive, and the titanium steel composite plate is very heavy, so relatively large lifting equipment is required for installation, and the titanium steel composite plate needs to be welded around, and more equipment is required for installation. Welders, so the installation requirements are higher and the construction is more cumbersome

In the prior art, there is another anti-corrosion inner cylinder that adopts a steel plate coating scheme to build an anti-corrosion inner cylinder. This kind of inner cylinder needs to be coated with scale on a large area, and the construction quality is not easy to guarantee during the large-area scale coating construction, and the scale coating is volatile and toxic, and the construction environment is harsh , which is harmful to construction personnel and has a negative impact on the surrounding environment. The coating is prone to cracking and falling off during subsequent use, and frequent inspection and repair is required
