Tail gas processing system

Abstract

The invention belongs to the technical field of exhaust-gas treatment, and provides a tail gas processing system. The tail gas processing system comprises an exhaust gas collection device, a spray tower, a photolysis catalyst device, an activated carbon absorption device and a chimney connected in series through pipelines. The spray tower comprises a tower body, the bottom end of the tower body isprovided with an air inlet, the upper end of the tower body is provided with an air outlet, and the tower body is provided with a swirling plate, a packing layer and an anti-fog filter layer in orderfrom bottom to top; the tower body is further provided with a water circulation device, and the water circulation device comprises a circulating water collector disposed at the bottom of the tower body and a circulating water spraying device disposed at the top of the tower body, the circulating water collector and the circulating water spraying device are connected by a circulating water pipe, and the circulating water pipe is provided with a circulating water pump. The equipment is tested, and the formaldehyde and total VOCs of the exhaust gas treated by the system reach the national emission limit.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a tail gas treatment system. Background technique [0002] Laminated paper is also called glued paper, which is widely used in the production of building templates. The laminated paper and wood-based panels are thermally pressed to form a building template, which is beautiful and has obvious advantages. The coated paper makes the surface of the building membrane smooth and flat, without causing any pollution to the building, and can strictly limit the release of harmful gases. [0003] In the production process of film paper, high energy consumption will generate a lot of exhaust gas. The government requires enterprises to meet environmental protection requirements before they can produce normally, especially exhaust emissions, which directly affect air quality and also affect the lives of people around them. When producing impregnated film paper, a smal...
