Catalytic bed furnace core structure with guide shield

Abstract

The invention relates to a catalytic bed furnace core structure with a guide shield. The structure comprises an upper end plate, a lower end plate and a furnace core outer peripheral plate; the upper end plate and the lower end plate are respectively fixedly mounted on the upper end and the lower end of the furnace core outer peripheral plate; a furnace core inner peripheral plate is arranged in the furnace core outer peripheral plate; gas inlet paths and gas outlet paths are alternatively arranged between the furnace core inner peripheral plate and the furnace core outer peripheral plate; the inlet of each gas inlet path is arranged on the upper end plate; the outlet of each gas inlet path is arranged between the lower end plate and the furnace core inner peripheral plate; the inlet of each gas outlet path is arranged between the upper end plate and the furnace core inner peripheral plate; the outlet of each gas outlet path is arranged on the lower end plate; a guide shield with an inversed rectangular pyramid structure is arranged at the lower face of the middle of the upper end plate. The catalytic bed furnace core structure is simple in arrangement and scientific and reasonable in design, the heat efficiency of the furnace core structure can be effectively improved, the heat loss is reduced, the heat recovery utilization rate can be improved, the temperature in the furnace core structure is more uniform during burning, and the burning efficiency and the purifying rate are improved.

Description

technical field [0001] The invention belongs to the field of catalytic beds, in particular to a catalytic bed furnace core structure with a guide cover. Background technique [0002] With the enhancement of people's awareness of environmental protection, the term PM2.5 has attracted more and more attention. Among PM2.5, the most harmful to people's health is industrial volatile organic pollutants. In the prior art, industrial volatile organic pollutants are mainly Using the catalytic combustion method, the existing catalytic bed furnace core structure is usually made of heat-resistant steel plates or industrial kiln masonry materials, and the air inlet and outlet are located at the upper and lower ends of the furnace core structure. Combustion, but there are the following problems: 1. The heat loss of the furnace core structure itself is large, and the heat recovery efficiency is low; 2. The temperature in the furnace core structure is not uniform, and the temperature in the...

[0002] With the enhancement of people's awareness of environmental protection, the term PM2.5 has attracted more and more attention. Among PM2.5, the most harmful to people's health is industrial volatile organic pollutants. In the prior art, industrial volatile organic pollutants are mainly Using the catalytic combustion method, the existing catalytic bed furnace core structure is usually made of heat-resistant steel plates or industrial kiln masonry materials, and the air inlet and outlet are located at the upper and lower ends of the furnace core structure. Combustion, but there are the following problems: 1. The heat loss of the furnace core structure itself is large, and the heat recovery efficiency is low; 2. The temperature in the furnace core structure is not uniform, and the temperature in the center is generally high, and the temperature at the edge is low, which reduces the industrial reliability. The combustion efficiency of volatile organic pollutants affects the purification rate of catalytic combustion
