Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide purification technology, specifically a carbon dioxide concentration monitoring and purification device. Background Technology

[0002] In industrial operations, it is often necessary to work in a closed environment. During the operation, the concentration of carbon dioxide in the closed environment gradually increases. In a high concentration of carbon dioxide atmosphere, operators are at high risk of carbon dioxide poisoning.

[0003] Most existing carbon dioxide concentration monitoring and purification devices use carbon dioxide absorbents to purify carbon dioxide. However, the carbon dioxide absorbents accumulate in the device and remain stationary. During absorption, the upper absorbent always works first, resulting in low utilization efficiency of the lower absorbent and causing some waste. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing carbon dioxide concentration monitoring and purification devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a carbon dioxide concentration monitoring and purification device. During use, a carbon dioxide detector measures the carbon dioxide content in the air. Under the action of a second drive motor, a centrifugal fan starts, and air enters the activated carbon box through a second filter. The activated carbon first adsorbs and removes dust from the air, and then enters the purification dish through an air pipe. The carbon dioxide absorbent absorbs the carbon dioxide in the air. Under the action of a first drive motor, a first gear rotates. Through the cooperation of the first gear and a second gear, a spiral stirring blade agitates the carbon dioxide absorbent in the purification chamber, causing the upper and lower layers of carbon dioxide absorbent to alternate back and forth. This solves the problem that most existing carbon dioxide concentration monitoring and purification devices use carbon dioxide absorbent to purify carbon dioxide, but the carbon dioxide absorbent accumulates in the device and remains in a static state. During absorption, the upper absorbent always works first, resulting in low utilization efficiency of the lower absorbent and causing waste to a certain extent.
