Rotational flow turbulent flue gas purification column

Abstract

The invention discloses a rotational flow and turbulent swirl ball flue gas purifying tower, which comprises a tower body, a driving device, a turbulent swirl ball layer, a rotating-stream tray layer and peripheral devices, and is characterized in that the turbulent swirl ball layer and the rotating-stream tray layer are arranged in the same tower body and are distributed up and down; a center pipe is vertically arranged at the middle part of the turbulent swirl ball layer and the rotational flow ply and is connected with the driving device. The rotational flow and turbulent swirl ball flue gas purifying tower can be used for debusting, desulfurizing, demist, washing and cooling the flue gas, has reliable performance, favorable adaptability, high desulfurization efficiency, simple operation, saved cost and convenient the maintenance, also avoids the scale blockage and has good popularization value.

Description

technical field [0001] The invention relates to the technical field of gas purification equipment, in particular to a flue gas purification tower. Background technique [0002] At present, there are two main structures of exhaust gas purification towers on the market: swirling plate type and turbulent ball type. For example, the Chinese patent number is 03256144.X, and the application date is July 28, 2003. The name of the invention is a large-flux and high-efficiency swirl plate tower desulfurization and dust removal device. This patent discloses a flux and high-efficiency swirl plate tower desulfurization and dust removal device, including water For the membrane dust collector, a multi-layer swirl plate tower is arranged inside the cylinder, and the swirl plate tower is composed of a blind plate, a swirl blade closely connected to the blind plate and an annular bracket for fixing the swirl blade. The device has high desulfurization and dust removal efficiency, low pressur...

AI Technical Summary

Problems solved by technology

Its advantages are low energy consumption, low operating cost, self-cleaning ability of the system, no clogging, closed water circulation, zero discharge of sewage, but the turbulence of the ball has a certain degree of back-mixing in each section, and it is relatively easy Deformation and cracking are only suitable for operations with a small number of mass transfer units (or theoretical plates), such as irreversible chemical absorption, dehydration, dust removal, direct contact heat transfer between gas and liquid at a relatively constant temperature, etc.

For this reason, people have improved the existing technology by connecting the two parts of the turbulent ball tower and the swirl plate tower in series, realizing complementary advantages, improving the desulfurization efficiency, and alleviating the fouling and blocking phenomenon, but its cost is relatively high. Complex structure, not conducive to maintenance
