Catalytic combustion bed furnace core structure with heater

Abstract

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

Description

technical field [0001] The invention belongs to the field of catalytic combustion beds, in particular to a catalytic combustion bed furnace core structure with a heater. Background technique [0002] The core structure of the existing catalytic combustion bed is usually made of heat-resistant steel plates or industrial kiln masonry materials, which mainly deal with industrial volatile organic pollutants that are most harmful to people's health in PM2.5. In the core structure, the air inlet and outlet are set at the upper and lower ends of the furnace core structure. Although the existing structure can realize catalytic combustion, 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 furnace core The temperature in the structure is not uniform, and the temperature is generally high in the center and low in the edge, which reduces the combustion efficiency of industrial volatile organi...

Although the existing structure can realize catalytic combustion, 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 furnace core The temperature in the structure is not uniform, and the overall temperature is high in the center and low in the edge, which reduces the combustion efficiency of industrial volatile organic pollutants and affects the purification rate of catalytic combustion
