Apparatus for filtering exhaust gas

The present invention relates to an exhaust gas filtration device, and more particularly, to remove toxic substances and dusts contained in the exhaust gas generated in the process of generating the exhaust gas containing the incineration process, the plating process, and other harmful substances, as well as high density multi-pore. The present invention relates to an exhaust gas filtering device that is easy to replace and clean filters.

In general, living in a contaminated atmosphere first affects the mucous membranes of the eyes, nose and upper respiratory tract, and then a physiologically reversible reaction occurs, and if exposed continuously, the symptoms worsen and cause disease.

Chronic diseases occur when these diseases occur repeatedly at low concentrations. The damage caused by air pollution is the most easily affected by the elderly and children with heart disease, circulatory diseases, etc. It is easy to receive the damage.

Depending on the degree of air pollution, the damage received is determined by the level of knowledge on health, the demand for health, and the level of society.

It is difficult to elucidate the causal relationship between cause and effect because many factors, such as pollutant type, concentration, topography and weather conditions, individual population population density, living environment and living conditions, are related to the health effects of air pollutants. .

Acute damage due to air pollution has already occurred as an air pollution event in London, etc. When a significant pollution phenomenon occurs when the disease is caused by air pollution in association with a significant decrease in children and the elderly, heart function or lung function. Leads to

Chronic damage, on the other hand, is the damage caused by living in the environment for a long time. Acute damage causes damage to the elderly, infants, the weak, and people with pneumonia in a short time, leading to death, while chronic damage gradually damages health.

In the acute case, the loss pattern can be easily detected by visual field reduction, mental change (life discomfort, discomfort, mental and physical fatigue), physiological effects, addiction damage, deterioration of cardiopulmonary disease, and secondary bacterial infection promotion. The chronic effects may be summarized as growth disorders, chronic respiratory disease (pneumonia, bronchitis, bronchiolitis, bronchiectasis, paroxysmal asthma, emphysema), hypertrophy of the heart, and carcinogenesis.

The filtration device for filtering the exhaust gas causing such damage is connected to the discharge end of the exhaust duct installed with a tubular blower for forcibly transporting the exhaust gas, and using the filtering means in which a filter is filled in a predetermined portion of the exhaust gas. Forced transfer to the inside of the filtration means with a tubular blower to allow the activated carbon filter to adsorb the harmful substances and dust contained in the exhaust gas as the exhaust gas passes through the filter.

However, the above-described conventional structure has a problem in that the use period of the filter is short and cannot be reused, and the filtration efficiency is lowered by allowing the filter to adsorb harmful substances and dusts of the exhaust gas only.

The present invention was devised in view of the above problems, and its purpose is to maximize the filtration efficiency of the exhaust gas by dissolving toxic substances and dusts adsorbed in the filter at the same time as the primary filter by the filter and dissolving them in the wash water. The present invention provides an exhaust gas filtration device that can be easily replaced and repaired and that can be reused since the filter is washed.
