Description

Technical Field

[0001] The present application belongs to the field of VOC control technology, and specifically relates to a VOC control device with sampling and detection functions. Background Art

[0002] VOC treatment equipment refers to equipment used to control, reduce and treat the emission of volatile organic compounds. VOC treatment equipment plays an important role in environmental protection. Common VOC treatments include VOC adsorption purification; VOCs in the gas are adsorbed and stored by adsorbents (such as activated carbon) to achieve the purpose of purifying the air. After adsorption saturation, the adsorbent can be regenerated and recycled for VOC oxidation purification; VOCs are oxidized and decomposed into harmless substances such as carbon dioxide and water by high-temperature oxidation, catalytic oxidation and other methods, which can effectively reduce atmospheric pollutant emissions and protect the environment and human health.

[0003] For example, the utility model patent with announcement number CN218239506U discloses a VOC treatment device with sampling and detection function, including a support plate, a first treatment tank is fixedly connected to one side of the top of the support plate, a protective shell is provided on the outer side of the first treatment tank, the protective shell is fixedly connected to the first treatment tank, a limiting slide groove is provided on one side of the protective shell, a stratified sampling component is provided on one side of the first treatment tank, and the stratified sampling component includes a movable plate. In the utility model, the gear is driven to rotate by rotating the adjustment bolt. Since a tooth plate is provided on one side of the movable plate, wherein the tooth plate and the gear are meshed with each other, when the gear rotates, the tooth plate will be driven to move, and the limiting of the limiting slide groove and the through groove will drive the movable plate and the detection tube to move. By utilizing the movement of the detection tube, the VOC reaction gas at different layers inside the first treatment tank can be extracted and detected, so that the detection is more accurate and convenient to operate.

[0004] However, during actual use, it was found that when the moving plate of the device drives the detection tube to move up and down to extract and detect the VOC reaction gas at different layers inside the first treatment tank, the VOC compounds inside the first treatment tank will overflow through the through groove, which will affect the surrounding personnel and the environment, and the overall sealing effect is poor. For this reason, a VOC control equipment with sampling and detection function is provided. Utility Model Content

[0025] The implementation principle of the embodiment of the VOC treatment equipment with sampling and detection function of the present application is as follows: the VOC volatile organic compounds from the outside are introduced into the interior of the VOC treatment tank 1 through the air pump 17, the connecting pipe 18, the air guide pipe 19 and the inlet pipe 2 for treatment.
