Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling water treatment, in particular to a cooling water treatment device for phosphate production. BACKGROUND

[0002] The crystallization process of phosphate production process materials requires the use of circulating cooling water to cool the crystallization kettle to ensure stable production process and safe operation of equipment. Due to the large scale of phosphate production, the amount of cooling water used is considerable. In order to reduce water consumption and production cost, the industry generally adopts the mode of recycling cooling water.

[0003] During the use of circulating cooling water, various impurities are introduced. At present, the conventional technical means for treating impurities in circulating cooling water for phosphate production in the industry is to use a combination process of "dosing and settling + filtration". In this process, the dosing and settling step usually involves adding flocculants (such as polyaluminum chloride, polyacrylamide, etc.) and coagulants to the cooling water. Through the adsorption and bridging action of the reagents, the dispersed fine impurity particles are aggregated to form larger flocs, which are then separated from the liquid by gravity in the settling tank. The supernatant after settling is then filtered to remove residual fine flocs and suspended impurities, so that the water quality meets the requirements for recycling.

[0004] At present, when dosing, the reagents are prone to float on the surface of the water in the reservoir, and it is difficult to mix with the water quickly and fully. The concentration of the reagents in the water body is uneven, and the fine impurities cannot be effectively aggregated to form flocs. In the area where the reagents are concentrated, useless precipitates are easily formed due to the high local concentration, which not only wastes reagents, but also increases the content of impurities in the water body.

[0005] Although the settled cooling water removes most of the large particle impurities, it still contains a certain amount of fine flocs and suspended particles. The existing filtration equipment has limited interception capacity for these fine impurities, and during the filtration process, the impurities tend to accumulate on the surface of the filter material to form filter cake, which causes the filtration resistance to rise rapidly and the filtration rate to decrease.

[0006] Therefore, the present application provides a cooling water treatment device for phosphate production to solve the above problems. SUMMARY
