Foam-increasing sulfur foam tank for production of acid from waste desulfurization liquid

Abstract

The invention discloses a foam-increasing sulfur foam tank for production of acid from waste desulfurization liquid. The foam-increasing sulfur foam tank comprises an inner barrel with an open upper end; the opening of the inner barrel is provided with a top cover plate; a foam inlet pie and a foam outlet pipe are arranged to pass through the side wall and are oppositely disposed on two sides of the side wall of the inner barrel; a foam filtering pipe is installed in the inner barrel; the inlet end of the foam filtering pipe is in communication with the foam inlet pipe, and the outlet end of the foam filtering pipe is in communication with the foam outlet pipe; and the lower end of the foam filtering pipe is provided with a plurality of filtrate ports along the length extension direction of the foam filtering pipe. Since the foam filtering pipe is installed in the inner barrel, one end of the foam filtering pipe communicates with the foam inlet pipe, and the other end of the foam filtering pipe communicates with the foam outlet pipe, sulfur foam and clear liquid flow through the foam filtering pipe after entering the inner barrel, most of the clear liquid and a part of the sulfur foam will leak from the filtrate ports, and sulfur foam with a small amount of clear liquid will be continuously transported to the next procedure; that is, the amount of the active component desulfurized foam which is delivered to the subsequent procedures is increased.

Description

technical field [0001] The invention relates to the technical field of desulfurization devices for environmental protection equipment, in particular to a foam-increasing sulfur foam tank for acid production from desulfurization waste liquid. Background technique [0002] In the process of making acid from desulfurization waste liquid, the front-end process needs to use a tank for collecting sulfur foam, and the desulfurization foam and part of the clear liquid produced by the regenerator are collected into the sulfur foam tank through overflow. However, in the continuous production process, the amount of clear liquid in the sulfur foam liquid flowing into the sulfur foam tank is relatively large, which relatively leads to a small amount of active ingredient desulfurization foam. If it is directly transported to the next process, the efficiency of desulfurization and acid production will be low, and it is easy to As a result, the energy consumption of the follow-up process is...

However, in the continuous production process, the amount of clear liquid in the sulfur foam liquid flowing into the sulfur foam tank is relatively large, which relatively leads to a small amount of active ingredient desulfurization foam. If it is directly transported to the next process, the efficiency of desulfurization and acid production will be low, and it is easy to The energy consumption of subsequent processes increases, therefore, it is necessary to efficiently enrich sulfur foam to reduce the amount of clear liquid
