Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of flue gas separation, and particularly relates to a device for separating traditional Chinese medicine moxa stick combustion flue gas. BACKGROUND

[0002] Moxibustion with medicine, as a precious gem of traditional Chinese medicine therapy, combines the dual advantages of medicine and moxibustion, and exhibits excellent therapeutic and health care effects. Its advantages lie in warming the meridians and dispelling cold, through the warming effect of moxa leaves and specific traditional Chinese medicine, penetrating into the meridians, dispelling internal cold, promoting blood circulation, and relieving pain and discomfort caused by cold evil. At the same time, moxibustion with medicine can also support yang and prevent loss of yang, enhance the yang qi of the human body, and improve the functions of viscera, which has significant effects on symptoms such as insufficient yang qi and internal organ prolapse. In addition, it also has the effects of promoting blood circulation and removing blood stasis, relieving swelling and pain, promoting blood circulation, eliminating blood stasis and swelling, and accelerating tissue repair. More importantly, moxibustion with medicine can regulate yin and yang, improve the constitution, and enhance the immunity of the human body, achieving the purpose of preventing disease and health care. In terms of medicinal components, moxibustion with medicine is rich in volatile oils, flavonoids, alcohols, aldehydes and other active substances. These components are released during the combustion process, and are inhaled through the respiratory tract and contacted through the skin, which plays a variety of pharmacological effects such as antipyretic, analgesic, anti-inflammatory, antibacterial and antioxidant, and promotes human health together.

[0003] During the combustion process of moxibustion with medicine, various by-products including tar are produced. Tar, as a complex mixture in this process, is mainly composed of incompletely combusted hydrocarbons, aromatic compounds and a small amount of heavy metal particles. In the practice of moxibustion with medicine, although tar is not a direct component of the treatment purpose, its existence also needs to be concerned. On the one hand, tar may be inhaled by the human body along with smoke during the moxibustion with medicine process, and long-term or large amount of inhalation may have certain impact on respiratory health, such as irritating the respiratory mucosa and causing symptoms such as coughing and asthma. On the other hand, tar is also an indirect reflection of the combustion efficiency and quality of moxibustion with medicine. High-quality moxa leaves and reasonable traditional Chinese medicine formula can burn more fully, reducing the generation of by-products such as tar, thereby improving the efficacy and safety of moxibustion with medicine. Therefore, there is an urgent need for a device that can effectively remove the tar produced by moxa stick combustion while releasing more effective components. CONTENT OF THE UTILITY MODEL
