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

Abstract

The invention discloses a foam-increasing sulfur foam tank for making acid from desulfurization waste liquid, which comprises an inner cylinder with an open upper end, a top cover plate is arranged at the opening of the inner cylinder, and a top cover plate is installed on the side wall of the inner cylinder A foam inlet pipe and a foam outlet pipe are installed through it, and the foam inlet pipe and the foam outlet pipe are relatively arranged on both sides of the side wall of the inner cylinder, and a filter pipe is installed in the inner cylinder, and the filter foam The inlet end of the pipe is connected with the foam inlet pipe, the outlet end of the foam pipe is connected with the foam outlet pipe, and the lower end of the foam pipe is provided with a plurality of filtrates along the length extension direction of the foam pipe. mouth. By installing a filter tube in the inner cylinder, one end of the filter tube is connected to the foam inlet tube, and the other end is connected to the foam outlet tube. After sulfur foam and clear liquid enter the inner cylinder, they will flow through the filter tube, and most of the clear liquid will flow through the filter tube. And part of the sulfur foam will leak from the filtrate port, and the sulfur foam with less clear liquid content will be continuously transported to the next process, which is equivalent to increasing the effective component desulfurization foam transported to the subsequent process.

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
