Problems solved by technology

[0012] Therefore, one of the main problems restricting the development of flue gas desulfurization technology is how to overcome the corrosion prevention and manufacturing difficulties of large spray desulfurization towers.
[0013] Although there are some measures in the prior art, such as adopting high-grade alloy steel, and adopting steel-lined rubber or resin glass flake paint, etc., either because the price is extremely expensive, it is difficult to be widely used, or because of the difficulty in construction and manufacture, it becomes unsuitable. reliable
At present, most desulfurization devices adopt the method of steel-lined resin glass flake coating. However, due to frequent start-up and shutdown, and construction and other reasons, the coating layer is easy to fall off, resulting in the core equipment of the desulfurization device cannot be used normally and for a long time. , must be improved

preparation example Construction

[0055] The preparation method of the above-mentioned composite smoke exhaust and sulfur removal tower comprises the following steps:

[0056] Subsection manufacturing of tower body 1:

[0057] (1) Mold preparation: prefabricated inner diameter and the lower section 101 of tower body 1 respectively, the same mold of middle section 102 and upper section 103, wax on the mold, as paraffin, to play a lubricating effect, then spread polyester film, polyester film The thickness is 0.06~0.12mm;

[0058] (2) The production of the inner layer: using the hand lay-up method, first brush the mixture of organic resin and resin curing aid on the outer surface of the polyester film, then spread the said surface felt, and then brush the resin and resin on the surface felt The mixture of curing aids, while brushing the mixture of resin and resin curing aids, rolling with rollers, so that the mixture of resin and resin curing aids is immersed in said surface felt, and the air bubbles are discha...

Embodiment 1

[0065] Preparation of the composite smoke and sulfur removal tower of Fig. 1 and Fig. 2:

[0066] The diameter of the tower body is 9m, the total height is 25m, and the top flue gas connecting pipe 2 is located at the center of the top of the tower.

[0067] The organic resin is a polymer of monobasic unsaturated organic acid and epoxy resin. The vinyl resin with the brand name Derakane 411 produced by Dow Company of the United States is used.

Abstract

The present invention provides one smoke eliminating and desulfurizing tower of composite material and its making process. The smoke eliminating and desulfurizing tower includes one tower body, one top fume pipe, one top cover, one absorbing liquid distributor, one middle fume pipe and one bottom plate. Its tower body, top cover and bottom plate are made of composite material comprising inorganic fiber 10-80 weight portions, organic resin 20-90 weight portions and resin curing agent in the amount of 0.01-0.1 of the organic resin. The smoke eliminating and desulfurizing tower of composite material has low cost, simple making process, high quality and long service life, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a device for removing sulfur oxides in flue gas discharged from a boiler and a manufacturing method thereof, in particular to a manufacturing material of the device. Background technique [0002] Boilers or thermal power plants that use coal or oil as fuel emit a large amount of flue gas. These flue gases contain harmful substances such as SOx, NOx, HCl and HF, among which SOx is the main substance that forms acid rain. Depending on the type of coal burned, SO 2 The content is usually 300-5000ppmv (1000-15000mg / Nm 3 )between. However, the amount of flue gas is huge. In terms of coal-fired boilers, the steam scale ranges from 35T / h to 2500T / h, the capacity of the generating set ranges from 6MW to 1000MW, and the flue gas amount varies from 50,000 Nm 3 / h to 2.5 million Nm 3 , SO 2 Emissions from 1,000 tons / year to 100,000 tons / year. Thanks to SO 2 It is an acidic gas. It is an effective method to remove SOx in the flue g...
