Special catalytic combustion bed for industrial volatile organic pollutants in PM2.5

Abstract

The invention relates to a catalytic combustion bed special for industrial volatilizable organic pollutants in PM 2.5 (particulate matter). A furnace inner enclosing plate is arranged in a furnace body outer enclosing plate; gas inlet paths and gas outlet paths are alternatively arranged between the furnace body inner enclosing plate and the furnace body outer enclosing plate; the inlet of each gas inlet path is arranged on an upper end plate; the outlet of each gas inlet path is arranged between a lower end plate and the furnace body inner enclosing plate; the inlet of each gas outlet path is arranged between the upper end plate and the furnace body inner enclosing plate; the outlet of each gas outlet path is arranged on the lower end plate; a gas inlet flow guiding shield is arranged on the middle, corresponding to the inlet of the gas inlet shield, of the upper end plate; a combustion gas flow guiding layer is arranged under the middle of the upper end plate; a heater is arranged in a furnace body corresponding to the outlets of the gas inlet paths; a catalyst layer is mounted on a catalyst support; a thermalcouple is mounted on the side wall of the furnace body. According to the catalytic combustion bed for the industrial volatilizable organic pollutants in PM 2.5, the heat efficiency of the catalytic combustion can be effectively improved, the heat loss can be reduced, the temperature in the catalytic combustion bed 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 combustion beds, in particular to a special catalytic combustion bed for industrial volatile organic pollutants in PM2.5. Background technique [0002] With the enhancement of people's awareness of environmental protection, people pay more and more attention to air pollution, especially the recent frequent smog weather, which makes PM2.5 more concerned, and industrial volatile organic pollutants in PM2.5 are harmful to people The most harmful pollutants to the body. At present, the catalytic combustion bed is the most used to treat industrial volatile organic pollutants. The catalytic combustion bed is usually made of heat-resistant steel plates or industrial kiln masonry materials. The existing catalytic In the combustion bed structure, the air inlet and the air outlet are located at the upper and lower ends of the catalytic combustion bed.

[0002] With the enhancement of people's awareness of environmental protection, people pay more and more attention to air pollution, especially the recent frequent smog weather, which makes PM2.5 more concerned, and industrial volatile organic pollutants in PM2.5 are harmful to people The most harmful pollutants to the body. At present, the catalytic combustion bed is the most used to treat industrial volatile organic pollutants. The catalytic combustion bed is usually made of heat-resistant steel plates or industrial kiln masonry materials. The existing catalytic In the combustion bed structure, the air inlet and the air outlet are located at the upper and lower ends of the catalytic combustion bed. Although the existing structure can realize catalytic combustion, there are the following problems: 1. The structure of the catalytic combustion bed furnace itself has a large heat loss, and the efficiency of heat recovery and utilization Low; 2. The temperature in the structure of the catalytic combustion bed furnace is uneven, 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
