Liquid environment protection energy-saving low-temperature filter and process thereof

Abstract

The invention provides a liquid environment protection energy-saving low-temperature filter and a process thereof, which relate to a low-temperature filter for separating other impurities from mild wine and a process thereof. The invention aims at solving the problem of filtration at the non-constant temperature of the exiting ordinary refrigerating filter and overcoming the defects of great operation difficulty, water resource waste and room temperature effect caused by the factor of the filtration at the non-constant temperature. The invention uses the normal temperature of the original liquid to carry out exchange with condensed liquid through an energy-saving exchanger, twice cold energy exchange and recovery of the cold energy of clean liquid after the filtration can be realized through the energy-saving exchanger, and the temperature of the condensed liquid really reaches the temperature reduction standard requirement of a refrigerating machine, so the goal that the refrigerating filter set works in the constant temperature filtering work requirement range is reached. The defects of a water cooling tower are avoided, and the goals of full utilization of energy sources, high efficiency, energy saving, environment protection and practicability are realized.

Description

technical field [0001] The invention relates to a low-temperature filter device for environmental protection and energy saving of liquid and its technology, most notably a low-temperature filter device for separating other impurities from low-alcohol wine and its technology. technical background [0002] At present, in the production process of a kind of liquid, especially low-alcohol wine is the most remarkable. The composition of wine is extremely complicated, and it is one of the precious heritages of traditional industries in my country. With the development of the times, people's awareness of healthy drinks has increased, and high-alcohol alcohol is developing towards low-alcohol alcohol. The state also advocates alcohol companies to develop solid-liquid combination products. There are tens of thousands of large and small wine companies in our country. Every time we go to a food wholesale market, the most obvious thing is that there are all kinds of wine. There is no b...

Problems solved by technology

According to the principle of low-alcohol wine release and return to turbidity at low temperature, some manufacturers use low-temperature filtration after freezing in cold storage to remove organic impurities in wine, but the energy consumption is huge, and the processing capacity is low, so this method cannot be filtered at a constant temperature and orderly. This method has been eliminated.

Others use general refrigerated filter units for filtration, and the air-cooled or water-cooled compressors are used to cool down. The air-cooled type consumes a lot of energy and the working temperature is unstable and difficult to use; Scaling and blockage in the radiator of the refr
