Description

Organic waste gas absorption, desorption, concentration and purification system and method capable of returning to temperature and controlling humidity

The present invention relates to a treatment system and method for volatile organic compounds, in particular to a treatment system and method which can utilize temperature-rising gas to return temperature and control humidity of the gas to be treated.

Organic solvents are widely used in many industries, and some organic solvents are easy to volatilize into gases at room temperature, so they are called Volatile Organic Compounds (Volatile Organic Compounds, VOCs), most of which are biologically toxic, so It needs to be treated before being released to the outside world.

As shown in Figure 1, the adsorption-desorption concentration wheel is often used to remove volatile organic compounds in the exhaust gas. The volatile organic compounds in the exhaust gas are adsorbed in the adsorption zone of the wheel, and then desorbed in the wheel. It is desorbed and concentrated in the zone, and then further processed in the back-end treatment equipment (such as incinerator).

In some processes (such as spraying process), the exhaust gas produced by the process contains a large amount of particulate matter, so a scrubber or other dust removal device is often used to wash the exhaust gas at the back end of the process to reduce the particulate matter in the exhaust gas. Therefore, the final exhaust gas is low in temperature and high in humidity. In addition, if the purification system is installed in a humid environment such as the seaside, or in rainy days At the same time, the humidity in the exhaust gas will also increase significantly.

However, the exhaust gas with low temperature and high humidity is not conducive to the removal efficiency of organic compounds by the hydrophobic zeolite of the runner. Generally speaking, under fixed relative humidity and other conditions, the higher the temperature of the exhaust gas, the lower the removal efficiency of the runner for organic compounds; taking isopropanol as an example, when the exhaust gas reaches 45°C, the removal efficiency of the runner for isopropanol is lower. The removal efficiency will drop to 92%, and the removal efficiency will decrease sharply as the temperature continues to increase; on the contrary, if the exhaust gas temperature is too low (for example, when it is close to or lower than the dew point temperature of the desorption gas), the surface of the runner may be lower than the desorption gas. The dew point temperature of the attached gas will condense and wet, resulting in a sharp drop in removal efficiency. On the other hand, when the temperature and other conditions are fixed, the higher the relative humidity of the exhaust gas, the lower the removal efficiency of the runner for organic compounds; taking isopropanol or acetone as an example, when the relative humidity of the exhaust gas reaches 85%, the runner The removal efficiency of isopropanol or acetone will drop sharply to 90%, and the removal efficiency will drop sharply with the increase of relative humidity.

In view of this, the main purpose of the present invention is to provide a system and method for absorbing, desorbing, concentrating and purifying organic waste gas that can return temperature and control humidity.

In order to achieve the above and other objectives, the present invention provides an organic waste gas adsorption-desorption concentration purification system that can return to temperature and control humidity, which is used to treat the untreated gas containing volatile organic compounds, and it includes at least one runner, the runner It has an adsorption area, a desorption area and a first cooling isolation area. The adsorption area is used to introduce the gas to be treated, to absorb at least a part of volatile organic compounds in the gas to be treated and send out an adsorption treatment gas. The desorption area is used for introducing a desorption gas for desorption of volatile organic compounds adsorbed by the runner and sending out a desorption treatment gas. The first cooling isolation area is between the adsorption area and the desorption area, and the first cooling isolation area is used to introduce a first cooling gas to reduce the temperature in the first cooling isolation area and send out a first heating gas, At least a portion of the first warming gas to be treated After the gas merges, it enters the adsorption zone.

In order to achieve the above and other objectives, the present invention also provides an organic waste gas adsorption-desorption concentration purification method capable of returning temperature and controlling humidity, which can be applied to the above-mentioned organic waste gas adsorption-desorption concentration purification system capable of returning temperature and controlling humidity, and it includes The following operating procedures are carried out substantially simultaneously: the first cooling operation procedure: introducing a first cooling gas into the first cooling isolation area to reduce the temperature in the first cooling isolation area and sending out a first heating gas; adsorption operation Procedure: A gas to be treated containing volatile organic compounds is combined with at least a part of the first heating gas and introduced into the adsorption zone, and at least a part of the volatile organic compounds is adsorbed in the adsorption zone, and then an adsorption treatment gas is sent out and the desorption operation procedure: introducing a desorption gas into the desorption area, the desorption gas desorbs the volatile organic compounds adsorbed by the runner from the runner and sends out a desorption treatment gas.

Because in the first cooling operation procedure, the temperature of the first heating gas can usually reach above 100°C, when it merges with the gas to be treated, the relative humidity in the gas can be reduced, and at the same time, the temperature can be easily controlled at an appropriate working temperature, Therefore, the removal rate of volatile organic compounds of the runner can be improved.
