Description
Technical Field
The invention relates to the technical field of air purification, in particular to a self-cleaning method of an air purification device of a ward building, which is mainly used for carrying out self-cleaning treatment on the air purification device of the ward building or an outpatient building of a hospital and continuously and automatically removing dust, flying floc, particulate matters and other impurities on the surface of the air purification device.
Background
With the development of medical service in China, the basic investment of China in the medical field is increased day by day, each large and three hospitals are provided with independent high-rise ward buildings and high-rise outpatient buildings, the high-rise ward buildings and the high-rise outpatient buildings are provided with central ventilation and purification devices, and the first step in the devices is to primarily filter dust, flying cotton, particulate matters and other impurities. However, at present, air pollution is serious, and especially seasonal wind sand, flying dust, plant floc and the like have great influence on primary filtration of the ventilation and purification device. If the purification of the initial filtration does not reach the standard, the subsequent filtration, sterilization, bacteria, virus and the like can be adversely affected. Particularly, the less the dust in isolation ward buildings, the less bacteria, the less the possibility of wound infection of patients, the less the possibility of contaminated preparations and the influence of precision instruments, and the direct relation between the purification treatment of visible air and the medical quality and the health of patients. The air purification device which is well built in a hospital ward building or an outpatient service building at present provides a safe and reliable working environment for medical workers, provides a comfortable and convenient medical environment for patients, and provides a safe and reliable sanitary environment for the society, which is an important responsibility of hospitals.
At present, dust, flying floc, particulate matters and other impurities in air are filtered in an air purification device of a hospital ward building or an outpatient building by using filter cloth arranged on a filter cloth frame at a fresh air inlet, namely, the filter cloth is used for filtering fresh air in the process that a fan of the air purification device sucks in the fresh air at the air inlet. Because the hospital ward building or the outpatient building have high requirements on air quality, the filter cloth needs to be cleaned or replaced after being used for a few days, however, the fresh air inlet is often arranged at a place which is not noticed by people, and is often not noticed by people even if people are not cleaned for a long time, so that a thick layer of dust is accumulated on the filter cloth, the ventilation resistance is increased, the noise of equipment is increased, and the air filtering quality is also reduced. Usually, the air purification device needs to be stopped when the filter cloth is cleaned or replaced, so that the work of medical staff still working in a building is influenced, the cost is high, the replacement workload is large, and dust can fall into an air duct carelessly. A common method for cleaning the filter cloth is to use a broom to sweep impurities on the outer surface of the filter cloth, but some dust always falls into an air channel in the filter cloth in the sweeping process, and after the air purification device is started, the dust enters a building along with fresh air, so that the quality of air in the building is adversely affected. Sometimes, the outer surface of the filter cloth is found to be too dirty and needs to be cleaned, in order to avoid dust from falling into the inner surface side of the filter cloth under the condition that the air purification device does not stop working, a worker can take a dust collector to clean impurities such as dust on the filter cloth, but the worker cannot accurately master the force of holding the suction nozzle when cleaning the filter cloth by using the dust collector, the suction nozzle of the dust collector can often collide with the filter cloth to cause vibration of the filter cloth, a small amount of dust on the filter cloth falls into the inner side of the filter cloth to pollute the air in a ward building, and the effect of losing one's account is achieved. On the other hand, the working time for manually cleaning the filter cloth is longer, the surrounding working environment is poorer, and certain harm is caused to the mind and body of a master worker.
Disclosure of Invention
The invention aims to make up the defects of the prior art and provides a self-cleaning method of an air purification device of a ward building, which can continuously and automatically clean sundries on filter cloth. The invention changes the static filter cloth frame in the air purification device into a rotatable filter cloth disc, fixes the suction nozzle of the dust collector on a slide block which can reciprocate left and right, when the air purification device of a ward building works, the self-cleaning device also synchronously works, namely, the disc paved with the filter cloth rotates slowly, the suction nozzle and the filter cloth keep a certain distance and reciprocate left and right along the radius of the disc, sundries on the filter cloth are cleaned continuously and circularly, the suction nozzle sucks a spiral line on the plane of the filter cloth, the filter cloth is kept clean all the time, and the sundries on the filter cloth are absorbed into a cloth bag of a cloth bag dust collector to be cleaned intensively, thereby saving manpower and material resources and improving the air quality in the ward building. The invention has simple structure, convenient and reliable use, easy maintenance and difficult occurrence of safety failure.
