Flue gas dewhitening equipment and system for exhaust chimneys of chemical plants

Abstract

The embodiment of the invention provides white flue gas removal equipment and system of a chemical plant exhaust chimney. The white flue gas removal equipment comprises a spraying device, an air inletpipeline, an exhaust pipeline, a gas flow rate control device and a gas flow control device; the spraying device comprises an air inlet, an air outlet and a baffle assembly allowing gas and / or liquidpasses through, and the baffle assembly divides the space inside the spraying device into two communicated parts; the baffle assembly comprises a first baffle plate and a second baffle plate which are overlapped and arranged; a first hole is formed in the first baffle plate; a second hole is formed in the second baffle plate; the first baffle plate and / or the second baffle is adjustable relativeto the relative position of the other baffle in the plane where the first baffle plate and the second baffle are located, so that the area and the shape of a hole structure formed by overlapping the first hole and the second hole are adjustable; and the gas flow rate control device is connected with the gas inlet pipeline; the gas flow control device is connected with the baffle plate assembly andis used for controlling the relative position between the first baffle and the second baffle so as to control the flow of the gas passing through the hole structure.

Description

technical field [0001] The present application relates to the technical field of exhaust gas treatment equipment, and in particular, the present application relates to a flue gas dewhitening equipment and system for exhaust chimneys of chemical plants. Background technique [0002] In recent years, with the continuous development of the industrial industry, the construction scale of chemical plants has continued to increase, the production capacity of chemical plants has continued to increase, and the smoke pollution caused by the production of chemical plants has become increasingly serious. With the continuous increase of environmental protection and governance, higher requirements have been put forward for the emission of high-temperature and high-humidity flue gas, and it is necessary to ensure that there is no flue gas and no water vapor in the chimney. The production process of the chemical plant is relatively complicated, and the products produced are also numerous. T...
