A high-efficiency voc treatment system using a new type of heat exchanger and its treatment process

Abstract

A high-efficiency VOC treatment system using a novel heat exchanger and its treatment process belong to the technical field of waste gas treatment equipment. It is characterized in that: the gas outlet of the pretreatment module is connected to the gas inlet of the catalytic combustion module, the gas outlet of the catalytic combustion module is connected to the atmosphere, a heat exchange unit is arranged between the power generation module and the gas outlet of the catalytic combustion module, and the power generation module passes through The wire is electrically connected with the catalytic combustion module and supplies power to the catalytic combustion module. This high-efficiency VOC treatment system using a new type of heat exchanger avoids polluting the environment, and can also fully utilize the heat of VOC waste gas after combustion to ensure self-supply of energy and effectively avoid energy waste; After treatment and catalytic combustion, it is discharged to the atmosphere, so as to effectively treat VOC exhaust gas. The power generation module uses the lower temperature gas after catalytic combustion and heat exchange to perform heat exchange and power generation through the heat exchange unit, and provides electric energy for the heating of the catalytic combustion module, thereby Improve the utilization rate of energy.

Description

technical field [0001] A high-efficiency VOC treatment system using a novel heat exchanger and its treatment process belong to the technical field of waste gas treatment equipment. Background technique [0002] VOC is a kind of volatile organic compound, which mainly comes from the waste gas emitted by petrochemical, pharmaceutical, printing, painting, motor vehicle, shoemaking and other industries. This kind of organic waste gas will cause great harm to human health, and it will interact with NO in the atmosphere 2 The reaction produces O 3 , making O in the lower atmosphere 3 When the concentration increases, photochemical smog is formed, which is harmful to human health and leads to crop production reduction.

Problems solved by technology

This kind of organic waste gas will cause great harm to human health, and it will interact with NO in the atmosphere 2 The reaction produces O 3 , making O in the lower atmosphere 3 The concentration rises, forming photochemical smog, which endangers human health and leads to crop yield reduction

[0003] The main existing VOC treatment technologies include regenerative thermal oxidizer technology (RTO) and catalytic combustion technology. Although RTO has high efficiency, it is bulky and expensive, so it is difficult to implement

In the existing catalytic combustion technology, the utilization rate of waste heat is low, that is, the heat exchange efficiency between the untreated gas and the burned gas is low, so it is necessary to supplement the heating of the catalytic combustion gas, which leads to high energy consumption and waste of heat. big problem

According to statistics, the temperature of the untreated gas after preheating is still about 150°C, and this part of the gas is directly discharged into the atmosphere, which will pollute the environment, and the heat of this part of the gas is not fully utilized, resulting in a waste of energy
