Glass fiber reinforced plastic filler-type catalytic desulfurization tower

Abstract

The invention discloses a glass fiber reinforced plastic filler-type catalytic desulfurization tower and belongs to the technical field of catalytic desulphurization equipment. The glass fiber reinforced plastic filler-type catalytic desulfurization tower mainly solves the problem that the existing desulfurization tower produces severe desulphurization corrosion, has a high maintenance cost and easily produces secondary pollution. The glass fiber reinforced plastic filler-type catalytic desulfurization tower is characterized in that a tower unit comprises a glass fiber reinforced plastic tower, nozzles, a flue gas outlet, a filler layer, a structured filler layer, a grating, strip beams, a main beam, stand columns, a circulation solution outlet and a flue gas inlet, the nozzles, the flue gas outlet, the filler layer, the structured filler layer, the grating, the strip beams, the main beam, the stand columns, the circulation solution outlet and the flue gas inlet are orderly arranged in the tower from top to bottom, the glass fiber reinforced plastic tower is composed of glass fiber reinforced plastic and an outer carbon steel by reinforcement, the flue gas outlet is arranged in the center of the top end of the tower, the nozzles are uniformly distributed below the tower top, the main beam is fixed to the stand columns and transverse wedge bricks, the main beam is orderly provided with the strip beams, the grating and the structured filler, and the flue gas inlet and the circulation solution outlet are arranged at the side of the lower part of the tower. The glass fiber reinforced plastic filler-type catalysis desulfurization tower has the characteristics of simple processes, desulfurizer recycle, no secondary pollutant and good desulphurization effects and can be used for desulphurization of flue gas with a concentration of several hundreds or many thousands ppm in a large-scale heat-engine plant and a chemical plant.

Description

technical field [0001] The invention belongs to the technical field of catalytic desulfurization equipment, and in particular relates to a packed type catalytic desulfurization tower of glass fiber reinforced plastics. Background technique [0002] Since the beginning of the 21st century, my country's economy has developed rapidly, and the demand for energy is also increasing. Coal, as a primary energy source, is still the main energy source in our country for a long period of time. In large power plants and chemical plants, many processes such as coal combustion, sulfuric acid production, metal smelting, etc. will produce a large amount of sulfur dioxide, which is one of the main pollutants in the atmosphere. A large amount of sulfur dioxide discharge not only seriously pollutes the environment, but also causes a huge waste of sulfur resources. Therefore, it is urgent to actively promote desulfurization technology, reduce sulfur dioxide emissions and protect the environment...
