Description

Fine filter for flue gas purification device

Technical Field

The utility model relates to a waste gas treatment technical field, concretely relates to a secondary filter for gas cleaning device.

Background

The traditional Chinese medicine treatment can be basically summarized as follows: the acupuncture, moxibustion and manipulations, such as bone-setting and massage, including other steaming, soaking and fumigation, can be generally summarized into the three above-mentioned therapies. Moxibustion, which is the main treatment of traditional Chinese medicine, is currently performed by traditional means. In the popular way, the smoke and flame, whether moxibustion performers or moxibustion sufferers are exposed to smoke generated after burning strong folium artemisiae argyi, the specific chemical components of the smoke cannot be completely clear and definite, but the concentration of suspended particulate matter PM2.5 and even PM20 in the smoke is actually present. The strong smoke makes moxibustion performers and moxibustion receivers feel uncomfortable and suffering from, and especially harmful smoke threatens the health of medical staff for long-term moxibustion practitioners. Folium artemisiae argyi has the functions of warming meridians and stopping bleeding, and menstrual period disorder is also known in the industry by female practitioners who stay in moxibustion smoke for a long time.

When implementing the moxa-moxibustion through traditional means, adopt artifical handheld moxa column, moxa stick or use simple moxa-moxibustion box to implement the moxa-moxibustion usually, it is poor to be subject to the ventilation condition not to have not purified moxa cigarette, whole space is diffused to moxa cigarette, the yellow-rooted miasma gas, working strength is big simultaneously, the moxa-moxibustion executor is because of easy tired, and the moxa column or the moxa cake that burns when leading to the moxa-moxibustion are difficult to keep adjusting well with human acupuncture point, the moxa column or the moxa cake that are difficult to control the burning keep reasonable safe distance with human acupuncture point, even cause the scald, cause moxa-moxibustion executor and both sides personnel psychological pressure of the person of being executed, influence the moxa-moxibustion effect. Although the moxibustion device has been improved, the human body, which is the most outstanding product of natural evolution, has many curves, and the curves are different from each other due to different body shapes, which means that the moxibustion device is changed into a great variety. Even if the curves of the cervical vertebra, the thoracic vertebra, the lumbar vertebra and the sacrococcygeal vertebra of the same person are only greatly different at the spinal part. At present, the influence of the human body curve difference on the moxibustion effect is not considered in moxibustion ovens and combustion chambers of all moxibustion instruments and equipment. The moxa-moxibustion case is all the plane design just to moxa-moxibustion acupuncture point radiation surface, and too narrow, and the moxa-moxibustion case is big to the poor opposite sex of moxa-moxibustion acupuncture point irradiation distance difference during causing the moxa-moxibustion, can not the moxibustion cure to some moxa-moxibustion acupuncture points even targets in place, and is low when high during moxa-moxibustion irradiation temperature, and not only the moxa-moxibustion implementer is difficult to control the moxa-moxibustion quality, and the moxa-moxibustion practitioner also because of the moxa-moxibustion irradiation temperature low when high can not feel at all, has increased psychological burden simultaneously, and the moxa-moxibustion effect is discounted. Moreover, the smog that moxa-moxibustion apparatus, equipment produced to moxa-moxibustion time chinese mugwort leaf burning of current, only with its simple collection, directly discharge to the open air through the pipeline, the useless flue gas causes destruction to near outdoor air quality. Is convenient for one person to benefit and can harm the public. Most folk moxibustion operators are located in downtown areas with dense population and living areas, and moxibustion is often a rare event which is an environment-friendly complaint object of nearby residents due to direct emission of moxa smoke by business owners. Even some moxibustion instruments have been disposed and have relied on activated carbon and have been strained the cotton filtration and adsorb the moxa-moxibustion flue gas, but activated carbon is very easy to lose efficacy because of adsorbing the fast poisoning of saturation in high concentration moxa-moxibustion smog, and the filter cotton also causes the hardening of filter cotton to lose efficacy, blocks up exhaust transfer passage because of a large amount of high viscosity, indissolvable, oily glue mixture bonding shutoff in the moxa-moxibustion smog. Therefore, even if a part of moxibustion operation places are provided with the activated carbon adsorption smoke purification device, harmful smoke can still permeate in the moxibustion area. In order to reduce the harm of smoke and waste gas of moxibustion, the maintenance work of the existing moxibustion apparatus is very frequent and tedious, and the cost of activated carbon, filter cotton, consumables and maintenance manpower is high. Thirdly, with the progress of science and technology, more artificial and natural physical therapy techniques appear and are applied, and practice proves that the physical therapy technique is effective. If the ultrasonic wave light waves with specific wave bands generated by applying modern scientific technology are used for irradiating human focus and fusing traditional Chinese medicine moxibustion, the energy generated during the burning of the folium artemisiae argyi and the penetration of beneficial physical substances in human tissues are more facilitated, and the moxibustion effect is better. The current units, mechanisms for carrying out these two types of physiotherapy, limited by the reasons of the instruments, are carried out separately in different departments, times, places and areas, making the continuous implementation of these two types of physiotherapy a luxury. By doing so, time and money of the implementer and the executed are wasted, the field space and the precious human resources of the implementer are wasted, and physical and psychological pains of the executed who is trapped by health are increased.

In conclusion, the existing moxibustion apparatus at home and abroad needs to make innovative innovations from the aspects of effectiveness, safety and reliability, labor intensity reduction of implementers, reduction of the number of people and efficiency improvement, environmental protection and integration with the modern new technology.
