Sorted-collection and recycling system for milking and milk-storing facility washing water

Abstract

The invention discloses a sorted-collection and recycling system for milking and milk-storing facility washing water. The system comprises a milking machine end, a primary cooling heat exchanger, a milk storage tank, a cooling water tank, a refrigeration system, a hot-water supply tank, an acid-liquid supply tank, an alkali-liquid supply tank, an acid-liquid collection tank, an alkali-liquid collection tank and a hot-water collection tank; a milk outlet pipeline of the milking machine end passes through the primary cooling heat exchanger to the milk storage tank; and the hot-water supply tank,the acid-liquid supply tank and the alkali-liquid supply tank are connected to the milking machine end and the milk storage tank through a washing pipeline, a washing liquid outlet of the milk storage tank is connected with the acid-liquid collection tank, the alkali-liquid collection tank and the hot-water collection tank through a pipeline, and the acid-liquid collection tank and the alkali-liquid collection tank are connected to the washing pipeline through a pipeline. The system disclosed by the invention can realize recycling of acid and alkali liquids; and the hot-water collection tankcan collect washing hot water for washing a milk hall.

Description

technical field [0001] The invention belongs to the technical field of milking facility flushing water treatment, and in particular relates to a system for classified collection and recycling of flushing water for milking and storage facilities. Background technique [0002] The traditional way to dispose of the washing water in milking and milk storage facilities is usually to discharge it directly to the environment without collecting it, but after each round of milking, it has to go through clean water at different temperatures, acid / lye, clean water and sewage. It is necessary to rinse with clean water before milking. The amount of rinse water is huge and the composition is complex. In addition to the residual milk protein and milk fat in the milk, it also contains the acid and alkali solution to remove the residual protein and milk fat in the milk. If not rationally and scientifically collected and harmlessly treated, it will pollute groundwater and soil, and cause wast...

Problems solved by technology

[0002] The traditional way to dispose of the washing water in milking and milk storage facilities is usually to discharge it directly to the environment without collecting it, but after each round of milking, it has to go through clean water at different temperatures, acid / lye, clean water and sewage. It is a necessary cleaning step to rinse with clean water again before milking. The rinse water is produced in a huge amount and has complex components. In addition to the residual milk protein and milk fat in the milk, it also contains the acid and alkali solution to remove the residual protein and milk fat in the milk.

If reasonable and scientific collection and harmless treatment are not carried out, groundwater and soil will be polluted, and energy consumption (flush water temperature usually ≥ 45°C) will be wasted

[0003] In addition, the acid and lye after washing also have a certain pH value, which has a certain recycling value, and they are directly discharged as waste liquid, which will not only cause pollution but also cause waste
