Special catalytic bed for industrial volatile organic pollutants in pm2.5

Abstract

The invention relates to a catalyzing bed special for industrial volatilizable organic pollutants in PM2.5 (particulate matter 2.5). The catalyzing bed is characterized in that heat insulation layers are fixedly and uniformly mounted on the outer wall of a furnace body exterior plate, a furnace body interior plate is arranged in the furnace body exterior plate, air incoming ways and air outgoing ways are alternatively arranged between the furnace body interior plate and the furnace body exterior plate, an inlet of each air incoming way is arranged on an upper end plate while an outlet of the same is arranged between a lower end plate and the furnace body interior plate, an inlet of each air outgoing way is arranged between the upper end plate and the furnace body interior plate while an outlet of the same is arranged on a lower end plate, an incoming air guide cover is arranged above the middle portion of the upper end plate corresponding to an air incoming cover inlet, a combustion gas guide cover is arranged above the lower portion of the upper end plate, and an outgoing air guide cover is arranged below the middle portion of the lower end plate corresponding to an air outgoing cover outlet. Heat efficiency of the catalyzing combustion bed is effectively improved, heat loss is reduced, temperature in the catalyzing combustion bed is more uniform during combustion, and combustion efficiency and purifying rate are improved.

Description

technical field [0001] The invention belongs to the field of catalytic beds, in particular to a special catalytic bed for industrial volatile organic pollutants in PM2.5. Background technique [0002] PM2.5 has become a household name, mainly because PM2.5 is closely related to the air pollution index. With the enhancement of people's awareness of environmental protection, people pay more and more attention to air pollution. Industrial volatile organic pollutants are the most harmful pollutants to people's health. At present, catalytic beds are most used to treat industrial volatile organic pollutants. Catalytic beds are usually made of heat-resistant steel plates or industrial kiln masonry materials. The enclosure structure, the air inlet and the air outlet in the existing catalytic bed structure are located at the upper and lower ends of the catalytic bed. Although the existing structure can realize catalytic combustion, there are the following problems: 1. The heat loss o...

[0002] PM2.5 has become a household name, mainly because PM2.5 is closely related to the air pollution index. With the enhancement of people's awareness of environmental protection, people pay more and more attention to air pollution. Industrial volatile organic pollutants are the most harmful pollutants to people's health. At present, catalytic beds are most used to treat industrial volatile organic pollutants. Catalytic beds are usually made of heat-resistant steel plates or industrial kiln masonry materials. The enclosure structure, the air inlet and the air outlet in the existing catalytic bed structure are located at the upper and lower ends of the catalytic bed. Although the existing structure can realize catalytic combustion, there are the following problems: 1. The heat loss of the catalytic bed furnace structure itself is large , the efficiency of heat recovery and utilization is low; 2. The temperature in the structure of the catalytic bed furnace is uneven, and the temperature in the center is generally high, and the temperature in the edge is low, which reduces the combustion efficiency of industrial volatile organic pollutants and affects the purification rate of catalytic combustion
