TW201444608A - Adsorption/desorption purification system capable of increasing condensation recycling efficiency - Google Patents

Abstract

The present invention relates to an adsorption/desorption purification system capable of increasing condensation recycling efficiency. The system makes use of a humidifier to spray water mist for increasing the humidity of the concentrated volatile organic compounds airflow that passes through the humidifier, so as to increase the dew point temperature of the concentrated volatile organic compounds airflow and decrease the dry bulb temperature, thereby increasing the condensation effect for the subsequent condensation devices. As a result, the present system is able to solve the problem that the efficiency of condensing and recycling volatile organic compounds in the prior art is low, and thus is provided with the functions of increasing the condensation recycling efficiency of volatile organic compounds and saving energy.

Description

Suction and desorption purification system for improving condensing recovery efficiency

The invention relates to a suction and desorption purification system for improving the efficiency of condensation recovery, in particular to a designer who increases the dew point temperature of a concentrated volatile organic gas stream by spraying water mist and lowers the temperature of the dry bulb, thereby improving the condensation recovery efficiency.

According to [FIG. 1], Volatile Organic Compounds (VOCs) can be purified by using a suction and desorption purification system including a suction and desorption device 10 and a condensation device 20; The adsorption and desorption device 10 is configured to adsorb volatile organic compounds and discharge the purified gas stream, and concentrate and desorb the adsorbed volatile organic substances by heating, and concentrate and desorb the volatile organic compounds and reuse a concentrated volatile organic material delivery tube. 30 is sent to the condensing unit 20 for condensation recovery.

After the secondary pressing, the volatile organic matter which is condensed and recovered by entering the condensing device 20 is concentrated and desorbed by heating, that is, the concentrated desorbed volatile organic matter enters the condensing device 20 at a high temperature for condensation recovery, so that the condensation is caused. The condensation effect of the device 20 is greatly degraded, and not only the volatile organic matter condensation recovery performance is inconsistency and energy consumption.

The main object of the present invention is to solve the problem that the prior art condensation recovery of volatile organic compounds is not effective, and has the effect of improving the recovery efficiency of volatile organic compounds.

Another object of the present invention is to have an energy saving effect.

In order to achieve the above effects, the structural features of the present invention include: a suction and desorption device for adsorbing volatile organic compounds contained in the purified gas stream to be discharged, and discharging the purified gas stream, and concentrating the adsorbed volatile organic compounds. Desorbed; a concentrated volatile organic material delivery tube coupled between the suction and desorption device and a condensation device; a humidifier disposed inside the concentrated volatile organic material delivery tube for concentrating the concentration of volatiles The organic gas stream sprays the water mist to increase the humidity; and the condensing device is configured to condense the humidified concentrated volatile organic gas stream to produce a condensate containing volatile organic compounds.

In addition, the type of the suction and desorption device includes a fluidized bed, a concentrated rotating ring and a concentrated rotating wheel.

First, as shown in FIG. 2, the present invention includes: a suction and desorption device 10, which adsorbs volatile organic compounds contained in the gas stream to be purified, and discharges the purified gas stream, and volatilizes the adsorbed gas. The organic matter is concentrated and desorbed, and the type of the adsorption and desorption device 10 includes a fluidized bed, a concentrated rotating ring and a concentrated rotating wheel (represented by a concentrated rotating wheel); a concentrated volatile organic material conveying pipe 30, linked Between the absorbing and desorbing device 10 and a condensing device 20, the volatile organic matter concentrated and desorbed from the absorbing and desorbing device 10 is sent to the condensing device 20; a humidifier 40 is disposed at the concentrated volatility The inside of the organic material conveying pipe 30 is configured to spray water mist through the concentrated volatile organic substance flow to increase the humidity, in addition to increasing the dew point temperature, the (dry ball) temperature can be lowered; and the condensing device 20 is configured to volatilize the concentrated after humidification. The organic matter stream condenses to produce a condensate containing volatile organic compounds.

Based on the configuration, the present invention helps the humidified organic volatile gas stream to increase the humidity by spraying the water mist by the humidifier 40, thereby increasing the dew point temperature of the concentrated volatile organic gas stream and lowering the dry bulb temperature. The subsequent condensation effect of the condensing device 20 is enhanced, so that the volatile organic matter condensation recovery performance and the energy saving effect are improved.

In summary, the technical means disclosed in the present invention have the invention patents such as "novelty", "progressiveness" and "available for industrial use", and pray for the patent to encourage the invention. German sense.
