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

Abstract

The invention discloses an adsorbent injection device based on adsorbent injection mercury removal. The device comprises an air suction pipe, an air pipe behind the air suction pipe is obliquely upward, an air suction assembly comprises two eccentric cylinders, blade sleeves are arranged in the two eccentric cylinders respectively, blades are arranged in the blade sleeves respectively in a sleevedmode, gears are arranged at the upper ends of the two eccentric cylinders respectively, neutralizing assemblies are arranged in the blades and the blade sleeves, recycling assemblies are arranged onthe side faces of the blades, cooling assemblies are arranged above the gears, and coal-fired waste gas can be sucked into the air suction pipe through the air suction assembly to be subjected to mercury removal, the cooling assemblies reduce the temperature of waste gas and liquefy most mercury vapor, the neutralizing assemblies neutralize the remaining mercury vapor and mercury oxide into substances difficult to volatilize, then the recycling assemblies recycle neutralized by-products and adsorption materials, and the by-products are prevented from being accumulated in the air suction pipe.The device provided by the invention has the characteristics of simultaneous desulfurization, mercury removal and mercury oxide removal 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] Based on the basic national conditions of our country, coal will still be the most important primary energy in the foreseeable future, but its large-scale mining and utilization have caused a sharp reduction in high-quality coal resources, which has intensified 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 hinder its development and utilization. [0003] When the existing sorbent injection device is used for coal, two sets of equipment for mercury removal and desulfurization are required, which is ve...
