An adsorbent injection device based on adsorbent injection for mercury removal

Abstract

The invention discloses an adsorbent injection device based on adsorbent injection for mercury removal, comprising a suction pipe, the air pipe behind the suction pipe is inclined upward, and the suction component comprises two eccentric cylinders, two The eccentric cylinders are respectively provided with blade sleeves, the blade sleeves are respectively sleeved with blades, the upper ends of the two eccentric cylinders are respectively provided with gears, the blades and the blade sleeves are provided with neutralization components, and the side surfaces of the blades are provided with neutralization components. A recovery component is provided, a cooling component is arranged above the gear, the suction component can suck the coal-fired waste gas into the suction pipe for mercury removal, the cooling component reduces the temperature of the exhaust gas and liquefies most of the mercury vapor, and the neutralization component removes the remaining mercury vapor. Mercury vapor and oxidized mercury are neutralized into non-volatile substances, and then the neutralized by-products and adsorbents are recovered by the recovery component to prevent by-products from accumulating in the suction pipe. and high adsorption efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial machinery, in particular to an adsorbent injection device based on adsorbent injection for mercury removal. Background technique [0002] Starting from my country's basic national conditions, coal will still be China's most important primary energy source in the foreseeable future, but its large-scale mining and utilization has caused a sharp reduction in high-quality coal resources, intensifying the contradiction between energy security and environmental protection . my country is rich in high-sulfur coal resources, and 7.80% of the national unified coal mines and key coal mines are high-sulfur coal, which is an important coal resource. However, the high-sulfur characteristics of high-sulfur coal itself hinder its development and utilization. [0003] When the existing adsorbent injection device is used for coal, two sets of equipment for mercury removal and desulfurization are required, whic...

AI Technical Summary

Problems solved by technology

[0003] When the existing sorbent injection device is used for coal, two sets of equipment for mercury removal and desulfurization are required, which is very inconvenient, and mercury will form oxidized mercury after oxidation, and there is a lack of equipment to neutralize oxidized mercury. At the same time, due to the continuous flow of exhaust gas, It is difficult to ensure the effective adsorption of the adsorbent
