Description
Technical Field
The invention belongs to the technical field of milking facilities, and particularly relates to a milking storage system with functions of waste heat recovery and washing water classification and collection.
Background
Milking systems typically include milking and milk storage facilities, and cooling and flushing systems.
The cooling system has the function of cooling the milk so that the milk is stored in a low-temperature environment, thereby ensuring the fresh-keeping effect of the milk. The temperature of freshly squeezed milk is generally about 37 ℃, and finally the milk is reduced to about 4 ℃ for storage through a cooling system, so that the cooling system consumes large energy and generates a large amount of heat exchange heat, but the cooling system of the traditional milking facility does not effectively collect and utilize the heat, so that the heat resources are wasted greatly.
The flushing system is used for flushing the whole milking and milk storage facilities, and the traditional disposal treatment mode of flushing water in the milking and milk storage facilities is usually not collected and directly discharged outside, but after each milking pass, the flushing system is subjected to the necessary cleaning links of adopting clear water, acid liquor/alkali liquor and clear water with different temperatures and flushing with clear water again before the next milking, so that the flushing water is huge in quantity and complex in composition, and besides the residual milk proteins and milk fat in milk liquid, the flushing system also contains acid and alkali liquor for removing the residual proteins and milk fat in milk. If reasonable and scientific collection and innocent treatment are not carried out, groundwater and soil can be polluted, and energy consumption (the temperature of flushing water is usually more than or equal to 45 ℃) is wasted.
In addition, the acid liquor and the alkali liquor after washing also have certain pH value, have certain recycling value, and directly discharge the acid liquor and the alkali liquor as waste liquid, so that pollution and waste are caused.
