Direct combustion type waste gas treatment and heat energy utilization system and utilization method

Abstract

The invention discloses a direct combustion type waste gas treatment and heat energy utilization system. The direct combustion type waste gas treatment and heat energy utilization system comprises an oven. The upper portion of the oven communicates with a hot air supply system. The hot air supply system comprises an incinerator. An exhaust port and a waste gas recovery port are formed in the incinerator. The waste gas recovery port communicates with the oven through a waste gas recovery pipeline. The exhaust port is connected with an exhaust pipeline. A circulating air pipe of the oven is connected with an air supply pipeline. An air supply fan is arranged on the air supply pipeline. One end of the air supply pipeline communicates with the circulating air pipe. The other end of the air supply pipeline communicates with the exhaust pipeline, or the other end of the air supply pipeline communicates with a fresh air source, and the air supply pipeline and the exhaust pipeline are connected through a heat exchanger. According to the direct combustion type waste gas treatment and heat energy utilization system, organic waste gas can be delivered into the incinerator to be burnt, and generated heat energy is supplied to the oven, so that the organic waste gas is treated, the heat energy is recovered and reutilized, and emission of polluting gas is reduced. The invention further discloses a waste gas treatment and heat energy utilization method. By the adoption of the method, the treatment rate of the organic waste gas is increased, and energy is saved.

Description

technical field [0001] The invention relates to a direct combustion waste gas treatment and heat energy utilization system, and also relates to a waste gas treatment and heat energy utilization method matched with the waste gas treatment and heat energy utilization system. Background technique [0002] While the rapid development of industry has brought wealth, it has also caused pollution to the environment. Organic waste gas is a common pollutant emitted by industry. The coating production line contains xylene, ethylene glycol and other organic compounds. If these waste gases are not treated Disposal and direct discharge into the atmosphere will cause serious pollution to the environment and endanger human health. Traditional organic waste gas purification methods include adsorption method, condensation method, and direct combustion method. These methods are prone to secondary pollution, high energy consumption, and are easily limited by the concentration and temperature o...
