Novel activated carbon desulfurization and denitration device

Abstract

The invention relates to a novel activated carbon desulfurization and denitration device. The novel activated carbon desulfurization and denitration device comprises an activated carbon silo, an activated carbon adsorption box, a conical material discharging bin, a star-shaped material discharging valve, a spiral material discharging device and an ammonia spraying reaction chamber, wherein activated carbon can be contained in the activated carbon silo, the activated carbon silo, the activated carbon silo, the activated carbon adsorption box, the conical material discharging bin and the star-shaped material discharging valve are closely connected from top to bottom sequentially, and the spiral material discharging device is connected with the activated carbon silo and the activated carbon adsorption box; and the spiral material discharging device is automatically capable of material refueling and material discharging, and the ammonia spraying reaction chamber is closely disposed betweenthe activated carbon silo and the activated carbon adsorption box. Through the device, simultaneous desulfurization and denitrification can be achieved, the activated carbon has a large adsorption area, high adsorption efficiency and small system pressure drop, and the device is provided with an own material storage trough, so that automatic refueling and material discharging are achieved throughthe spiral material discharging device, and the automation level is high.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification equipment, in particular to a novel activated carbon desulfurization and denitrification device. Background technique [0002] my country is rich in coal resources. 75% of the primary energy is coal and is mainly used for combustion. The gas pollutants produced by coal combustion are mainly SOx and NOx, which will cause ecological problems such as acid rain. The concentration of SOx and NOx in the boiler flue gas of thermal power plant is not high, but the total amount is large. If the traditional method is used to desulfurize and denitrify separately, it will not only occupy a large area, but also have high investment, management and operation costs. Activated carbon adsorption combined with desulfurization and denitrification technology has the advantages of being able to realize resource utilization of pollution control products, recyclable adsorbents, and high desulfurization and...

Problems solved by technology

[0004] At present, there are two main types of activated carbon combined desulfurization and denitrification devices in the market. One is a split device, where the desulfurization tower and denitrification tower are set separately. It is separated from the denitrification section by a porous partition. This kind of device can realize automatic loading and unloading, but it needs to set up a discharge distributor, the structure is complex, and the activated carbon exists in the form of accumulation, the carbon layer is thicker, and the pressure drop is larger.
