Chemical filtering device

Abstract

The filter device for chemical industry includes a filter tank, the filter tank is a three-layer structure, including the first filter zone, the second filter zone and the third filter zone, and a primary filter is arranged between the first filter zone and the second filter zone, A re-filter is provided between the second filter area and the third filter area, and a stirring device is provided in the first filter area. The stirring device includes a plurality of propellers, and each propeller is composed of multiple blade-type paddles. It has a better cutting and crushing effect on the particles in the waste liquid, and can initially prevent the blockage of the filter and the discharge port. The combination of the primary filter and the re-filter has a good separation effect on the waste block or granular objects in the waste liquid, and can effectively prevent the waste in the waste liquid from blocking the discharge port. It is widely used in the chemical industry. It has a very good effect in wastewater treatment.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a filter device used in the chemical industry. Background technique [0002] In the chemical industry, many reactions are carried out in reactors, and the products after the reactions need to be treated, so a large amount of wastewater will be generated, which often contain lumps or particles of different sizes and particle sizes. If the wastewater reaches the standard, it is often treated with a filter device. The traditional filter device is a layer of filter screen or filter plate set in the filter bucket, the filtering effect is not good, and the outlet of the filter bucket and the filter screen or filter plate are often blocked. Leak holes not only significantly affect the filtering effect, but also need to frequently replace these water outlets and filter screens or filter plates, resulting in waste of enterprise costs. And the water that seeps through from filter screen o...

[0002] In the chemical industry, many reactions are carried out in reactors, and the products after the reactions need to be treated, so a large amount of wastewater will be generated, which often contain lumps or particles of different sizes and particle sizes. If the wastewater reaches the standard, it is often treated with a filter device. The traditional filter device is a layer of filter screen or filter plate set in the filter bucket, the filtering effect is not good, and the outlet of the filter bucket and the filter screen or filter plate are often blocked. Leakage holes not only significantly affect the filtering effect, but also need to replace these water outlets and filter screens or filter plates frequently, resulting in waste of enterprise costs

Moreover, the water permeated from the filter screen or filter plate often causes a violent impact on the water outlet, making the water outlet parts more easily damaged, which greatly affects the normal production of the chemical plant.
