Fixed bed adsorption reactor

Abstract

The invention discloses a fixed bed adsorption reactor, and relates to an adsorption reactor. The invention provides a glass fixed bed adsorption reactor which is convenient to use, stable and reliable and has a specific diameter-variable angle and a ground joint and of which the inside is embedded with a No.3 sand chip. An upper reactor main body and a lower reactor main body are arranged; the upper reactor main body is inserted into the lower reactor main body; the connecting position of the upper reactor main body and the lower reactor main body adopts the ground joint; the upper reactor main body is a cone; the top of the upper reactor main body is provided with an air inlet; the diameter-variable angle of the air inlet and the upper reactor main body is 28 to 32 DEG; the lower reactor main body is provided with a lower cylinder and a lower cone which are integrated; the bottom of the lower cone is provided with an air outlet; the diameter-variable angle of the air outlet and the lower cone is 28 to 32 DEG; and the sand chip is arranged in the lower cylinder.

Description

technical field [0001] The invention relates to an adsorption reactor, in particular to a glass material fixed-bed adsorption reactor with a specific variable diameter angle, a frosted interface, and 3# sand chips embedded inside. Background technique [0002] As a global and persistent toxic pollutant, mercury has attracted widespread attention from scholars and governments around the world. On March 15, 2005, the EPA enacted the Clean Air Mercury Act. The bill stipulates that by 2018, the level of mercury emissions should be reduced by 70% based on 1999 levels. [0003] At present, most researches related to mercury pollution control focus on activated carbon injection mercury removal technology. It injects activated carbon into the flue gas flow between the air preheater and the dust removal equipment (electrostatic precipitator, bag filter, etc.), so that the activated carbon absorbs mercury from the flue gas and is then captured by the dust removal equipment together ...

Problems solved by technology

[0007] 1. Inlet conditions The sudden expansion of the cross section of the gas flow channel entering the reactor from the inlet pipe and the sudden change of the flow direction of the gas flow entering from the side inlet pipe will lead to uneven distribution of the gas flow on the cross section of the reactor bed

[0008] 2. Catalyst bed filling conditions Uneven
