Description

Waste gas treatment equipment and system

Technical Field

The utility model discloses be applied to waste gas and environmental protection field. In particular to waste gas treatment equipment and a system.

Background

The existing waste gas treatment mode is to treat waste gas by a spray tower, and the waste gas is filtered by adopting a filler and top spray water mode. The waste gas enters from the bottom of the spray tower and flows out from the top. And the spray water enters from the top of the spray tower to spray and wash the waste gas and then flows out from the bottom. On one hand, the above mode has the defects that the waste gas is contacted with water and convected in the spray tower to play a washing role, but the water flow falls fast, the contact time of the waste gas and the water is insufficient, the waste gas cannot be fully contacted, and the washing is not thorough. On the other hand, the long-term scouring of the water flow in the spray tower scours or impacts the internal structure and the filler, so that the filler is easy to collapse and the structure is easy to damage. Moreover, because the spraying of rivers has increaseed the humidity of exhaust gas, must dispose defroster or other water trap to its processing, increased the processing procedure, the process is more loaded down with trivial details.
