Waste gas purification tower

Abstract

The invention relates to a waste gas purification tower which comprises a purification tower body; the top of the purification tower body is provided with an exhaust hole; an air inlet hole is formed in one side surface of the bottom of the purification tower body; the purification tower body is internally and sequentially provided with a spray layer, a dehydration layer and an activated carbon layer from bottom to top; a photolysis purifier is arranged above the activated carbon layer; the bottom of the purification tower body is provided with a water storage device; a water outlet hole of the water storage device is connected with a water purification device; a water outlet hole of the water purification device is connected with a spray pipe in the spray layer. Larger particles of dust can be left on a filter screen, the speed of waste gas entering the spray layer is slowed down, small particles of the dust can be reserved by spraying, oil fume in the waste gas can be decomposed by the photolysis purifier, and formed carbon dioxide and water can be directly discharged outside; after the waste gas purification tower is adopted, the odor and bacteria in the waste gas can be removed, the waste gas is not required to be purified for a second time after being purified and can be directly discharged into the air, and the environment is not polluted.

Description

technical field [0001] The invention relates to the field of environmental protection technical equipment, in particular to an exhaust gas purification tower. Background technique [0002] At present, waste gas treatment is the pretreatment of waste gas generated in industrial sites and factory workshops before being discharged to the outside, so as to meet the national standards for external discharge of waste gas. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air sterilization, disinfection and purification, etc. Waste gas treatment equipment is widely used in chemical plants, pharmaceutical factories, electronics factories, printing plants, painting workshops, Painting factories, food factories, rubber factories, plastic factories, galvanizing workshops, paint factories, petrochemical industries and other places that generate dust, peculiar smell, and smoke. At presen...

General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air sterilization, disinfection and purification, etc. Waste gas treatment equipment is widely used in chemical plants, pharmaceutical factories, electronics factories, printing plants, painting workshops, Painting factories, food factories, rubber factories, plastic factories, galvanizing workshops, paint factories, petrochemical industries and other places that generate dust, peculiar smell, and smoke. At present, although many manufacturers have carried out exhaust gas treatment, the exhaust gas emitted by them is It will still affect the environment. Such waste gas cannot be directly discharged into the air, and it needs to be purified twice, which will increase the time of waste gas treatment, reduce work efficiency, and increase the cost of waste gas treatment.
