Description

Technical Field

[0001] The utility model belongs to the technical field of algaecide production, in particular to a bactericidal algaecide liquid filtering device. Background Art

[0002] Bactericides and algaecides, also known as biocides or fungicides, are mainly used to control the growth of microorganisms in cooling water systems. They can kill microorganisms and decompose residual cells. They have a killing effect on bacteria, fungi, algae, anaerobic bacteria, iron bacteria, nitrifying bacteria, sulfate-reducing bacteria, etc. Bactericides and algaecides are widely used in petroleum, chemical, metallurgy, electric power, oil fields, fertilizers and other industries. Bactericides and algaecides also have the characteristics of strong permeability, low toxicity, broad spectrum and high efficiency, and are relatively friendly to the environment.

[0003] In the prior art, unreacted raw materials or by-products are generated during the production process of fungicides and algaecides, as well as some unstable or difficult to decompose substances. These substances need to be removed by filtration to ensure the purity and quality of the product.

[0004] During long-term use and observation, it was found that most of the current bactericidal algaecide filtration devices use a single filter for filtration. However, the impurities and residues in the bactericidal algaecide solution have different particle sizes. In order to ensure the filtration effect, a filter with a smaller pore size is often used to filter the impurities. However, the impurities accumulate quickly on the surface of the filter, causing the filter to become blocked, affecting the filtration efficiency of the bactericidal algaecide solution.

[0005] To this end, the utility model provides a bactericidal algaecide liquid filtering device. Utility Model Content
