Description

Technical Field

[0001] The invention relates to the technical field of waste gas adsorption treatment, and in particular to a VOCs waste gas treatment device. Background Art

[0002] VOCs waste gas, also known as volatile organic compounds, refers to organic compounds that have high saturation, low boiling point, small molecular weight, and are easy to volatilize at room temperature under standard conditions. When treating VOCs waste gas, adsorption, combustion or biological methods are generally used to complete the treatment of VOCs waste gas. When using the adsorption method to treat VOCs waste gas, it is necessary to go through pretreatment, adsorption and desorption processes.

[0003] The existing Chinese patent application with application number CN113457332A discloses a VOCs waste gas treatment device, including a base, a filtering mechanism fixedly installed on the top of the base, the filtering mechanism including a first round tank, a first conduit fixedly installed on one side of the first round tank, the first conduit penetrates the first round tank and is fixedly connected to the first round tank, a blower is fixedly installed on the end of the first conduit away from the first round tank, a second conduit is fixedly installed on the top of the first round tank, the second conduit penetrates the first round tank and is fixedly connected to the first round tank, a plurality of linearly arranged first filter plates are fixedly installed in the first round tank, an adsorption mechanism is fixedly installed on the top of the base, and the adsorption mechanism includes a second round tank; the invention can absorb particulate pollutants in VOCs waste gas, ensure the cleanliness of the reagent for absorbing VOCs waste gas, and at the same time ensure the effect of the reagent adsorbing VOCs waste gas.

[0004] However, the VOCs waste gas treatment device has the following defects when used:

[0005] 1. When existing VOCs waste gas treatment devices treat VOCs organic matter in waste gas, they generally use adsorbents (such as activated carbon and other materials) to complete the treatment operation. However, in actual operation, the adsorbents (such as activated carbon and other materials) have poor adsorption effects on VOCs organic matter in waste gas. At the same time, it is difficult to quickly and conveniently remove the VOCs organic matter adsorbed inside the adsorbent (such as activated carbon and other materials), which makes it inconvenient to continuously treat the VOCs organic matter in the waste gas.

[0006] 2. When the existing VOCs waste gas treatment device treats VOCs organic matter in the waste gas, large impurities in the waste gas will also adhere to the adsorbent (activated carbon and other materials) that adsorbs VOCs organic matter, affecting the efficiency and effect of continuously treating VOCs organic matter in the waste gas.

At the same time, when driving the stirring blades to rotate, the drive motor that drives the stirring blades to operate can synchronously drive the assembly frame and the activated carbon adsorption block to rotate, and perform a rotational adsorption operation on the VOCs organic matter in the pretreated waste gas, thereby improving the speed of adsorption of VOCs organic matter and the efficiency of waste gas treatment.

[0088] In the VOCs waste gas treatment device of the present invention, when the VOCs organic matter in the waste gas is adsorbed and the treated gas is discharged, the power module 902 is started to operate, and the power is transmitted to the inside of the heating coil 903 through the wire, and the heating coil 903 is started to operate to generate heat, and the VOCs organic matter adsorbed inside the activated carbon adsorption block 807 is desorbed. At the same time, when the middle shaft 801 rotates, the rubber middle rotating seat 901 and the heating coil 903 that are movably connected inside thereof will not rotate, ensuring that the rotation of the middle shaft 801 will not affect the normal operation of the heating coil 903.
