Description

Wet washing tower for medical waste incineration tail gas treatment

Technical Field

The utility model relates to a wet scrubbing tower technical field especially relates to a wet scrubbing tower is used in medical waste incineration tail gas treatment.

Background

With the improvement of environmental protection requirements, part of key areas begin to implement stricter standards, the traditional semi-dry method in the waste incineration industry cannot meet the emission requirement of acidic substances, a more efficient wet washing technology must be adopted, and higher requirements are provided for the absorption efficiency of a wet washing tower. At present, the development of wet scrubbing towers in the thermal power industry is mature, but the problem that the flow field of flue gas is uneven still commonly exists, compared with the flue gas in the medical waste incineration industry, the wet scrubbing towers have the characteristics of small flue gas amount, large working condition change and the like, and the influence of the uneven distribution of the flow field of the small-diameter tower on the absorption efficiency is more obvious.

The existing wet scrubbing tower is characterized in that a flue gas inlet is usually arranged on the side surface of the middle lower part of a tower body and slightly inclines downwards, the flue gas flow rate at the flue gas inlet side is low, and the flue gas flow rate at the opposite side is high, so that the flue gas enters the scrubbing tower and rushes to the tower wall at the opposite side and then upwards. In order to improve the uniformity of a flow field, most of the prior art is to add flow equalizing devices, including additional rectifying grids, turbulent layer pipelines, rotary convergence coupling devices and the like, but the technologies have the disadvantages of large pressure loss and increased energy consumption. In the existing wet desulphurization tower, the auxiliary spraying layer is generally arranged on a flue gas flow path from a flue gas inlet to the opposite side tower wall, the spraying direction faces the flue gas inlet, and high-efficiency mixing and mass transfer are realized and the uniformity of a flow field is improved by high-speed hedging of flue gas and liquid drops. But the flue gas discharge process after spraying has a small amount of flue gas to carry steam to discharge, and the flue gas that carries steam is easily attached to the inner wall of chimney, and the knot is thicker more, leads to the flue gas to discharge comparatively difficultly.
