AI Technical Summary

Technical Problem

In existing industrial waste gas desulfurization devices, particulate impurities such as dust, coal ash, and sulfide particles are prone to deposit inside the desulfurization tower, leading to blockage and reduced efficiency of the desulfurizing agent, thus increasing maintenance costs.

Method used

The filter uses a scraper and nozzle structure. The scraper slides to remove particulate impurities from the filter plate, and the nozzle sprays sodium hydroxide solution for desulfurization. At the same time, sealing gaskets and fasteners simplify the installation and removal of the filter plate.

Benefits of technology

It effectively removes particulate impurities, prevents clogging, maintains the filter plate in a high-efficiency working state, reduces manual intervention and downtime, and improves desulfurization efficiency and work efficiency.

Abstract

The utility model relates to the technical field of industrial waste gas, and provides an industrial waste gas desulfurization device which comprises a desulfurization tower, a smoke outlet pipeline fixedly mounted at the top of the desulfurization tower, a feeding pipeline fixedly mounted on the rear side of the interior of the desulfurization tower, a smoke inlet pipeline fixedly mounted on the left side of the interior of the desulfurization tower, and a motor, the motor is fixedly mounted at the top of the smoke inlet pipeline, a rotating plate is fixedly mounted at the bottom of the motor, and a movable rod is arranged on the left side of the bottom of the rotating plate; when the desulfurization tower is used, particle impurities in waste gas can be effectively removed and prevented from blocking pipelines and equipment in the desulfurization tower through the arrangement of the scraping plate and the spray head structure, and meanwhile, the scraping plate can slide on the left side of the filter plate to scrape the particle impurities so as to timely remove the particle impurities on the filter plate; therefore, the filter plate is always kept in a high-efficiency working state, the reduction of the filter efficiency caused by dirt accumulation is avoided, and the manual intervention and the downtime are reduced.
