Carbon-based catalyst regeneration device and process

Abstract

The invention discloses a carbon-based catalyst regeneration device and a process thereof. The top of the device is provided with a feeding port, and the bottom is provided with a discharging port. Adesorption section, a drying section and a recovery section are sequentially arranged from the feeding port to the discharging port. A partition plate is arranged in the feeding port; the discharge port is provided with a sliding plate; the desorption section is provided with a high-temperature water vapor inlet, a high-temperature water vapor outlet and a corrugated baffle plate; the drying section comprises a top material conveying area, a middle material conveying area and a bottom material conveying area, each material conveying area comprises a feed orifice plate and a material conveyingpipe, and the drying section is also provided with a drying gas inlet, a drying gas outlet, a middle baffle orifice plate, a drying gas outlet and a bottom air vent; the recovery section comprises a conveying pipe, a feed orifice plate, a discharge orifice plate, a cooling gas inlet, a cooling gas outlet and a baffle orifice plate; and the drying gas inlet is communicated with the high-temperaturewater vapor outlet. The regeneration device can reduce the energy consumption for heating regeneration, improve the pore structure of a carbon-based catalyst, improve the adsorption capacity, avoid the ignition of the catalyst, and reduce the chemical and physical loss of the catalyst.

Description

technical field [0001] The invention belongs to the technical field of industrial tail gas purification, and in particular relates to a carbon-based catalyst regeneration device and process. Background technique [0002] In the integrated removal technology of flue gas pollutants with carbon-based catalysts, carbon-based catalysts act as adsorbents and catalysts, and can simultaneously remove sulfur dioxide, nitrogen oxides, fluorides, soot, mercury and other heavy metal harmful substances in flue gas , and the process basically does not consume water, and the desulfurization by-products can also create economic benefits. Carbon-based catalysts can be recycled after being regenerated. It is a high-efficiency, energy-saving, and consumption-reducing flue gas purification technology. It has broad application markets in industries such as electric power, steel, smelting, and food. [0003] At present, the commonly used carbon-based catalyst regeneration method in industry is h...
