Photocatalytic washing type industrial waste gas purification device

Abstract

The invention provides a photocatalytic washing type industrial waste gas purification device belonging to the field of environmental protection and purification. The industrial waste gas purificationdevice comprises a filter tank, a catalytic reaction box, a spray box and a return pipe, wherein a stirring rod is arranged on the left side of a motor; a dust collection box is arranged at the lowerend of a dust outlet hopper; a second filtering net is arranged on the upper side of a first filtering net; an activated carbon layer is arranged on the second filtering net; a catalytic reaction layer is arranged on the lower side of an inner cavity of the catalytic reaction box; the spray box is arranged on the right side of the catalytic reaction box; and an exhaust fan is arranged on the right side of the spray box. According to the device disclosed by the invention, a photocatalytic pipe is arranged on the upper side of the inner cavity of the catalytic reaction box, and has a function of rapidly treating waste gases by utilizing photocatalytic reaction; the upper end of a water pump is respectively connected with a first spray header device and a second spray header device by virtueof a water pipe, and a washing dust removal function is realized; and the device has the characteristics of being simple in manufacturing process, high in practicality and excellent in waste gas purification effect.

Description

technical field [0001] The invention relates to an environmental protection purification facility, in particular to a photocatalytic water washing type industrial waste gas purification device. Background technique [0002] As cities become more and more modernized, there are more and more industrial models, and the quality of people's living environment becomes worse and worse; waste gas refers to the toxic and harmful gases discharged by human beings in the process of production and life, especially chemical plants , iron and steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted is very smelly, which seriously pollutes the environment and affects human health. At present, the air pollution is becoming more and more serious. Industrial waste gas cannot be directly discharged into the atmosphere. If the direct discharge is large In the atmosphere, it will cause environmental pollution. In the existing technology, the treatment e...

[0002] As cities become more and more modernized, there are more and more industrial models, and the quality of people's living environment becomes worse and worse; waste gas refers to the toxic and harmful gases discharged by human beings in the process of production and life, especially chemical plants , iron and steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted is very smelly, which seriously pollutes the environment and affects human health. At present, the air pollution is becoming more and more serious. Industrial waste gas cannot be directly discharged into the atmosphere. If the direct discharge is large In the atmosphere, it will cause environmental pollution. In the existing technology, the treatment effect on waste gas is not good, the gas cannot be completely purified, and the effect of environmental protection cannot be achieved; because of some factors such as unreasonable structural design, the treatment effect is not good. , fail to meet the discharge requirements, and still cause pollution to the environment after discharge
