Problems solved by technology

However, this kind of equipment removes the moisture in the feed liquid by means of high temperature and high pressure. The disadvantages are: 1. The energy consumption cost is high, and the process needs to be heated to generate a large amount of steam, which consumes a lot of energy; 2. During the concentration process, this This kind of traditional evaporation equipment needs to heat the feed liquid. Low heating intensity will lead to low evaporation efficiency. If the heating intensity is too strong, some active substances and some nutrients that may be contained in the feed liquid will be destroyed; 3. Through the evaporation equipment It can only remove 10% of water, which often cannot meet the requirements of enterprises for relatively high concentration, so the efficiency of this kind of concentration equipment is low
However, the disadvantages of this kind of concentration equipment are as follows: 1. High energy consumption. As the concentration progresses, the total solid content in the feed liquid gradually increases. In order to overcome the higher osmotic pressure, it is necessary to provide a power increase for the system’s standby operating pump. Second, limited by the maximum pressure of conventional reverse osmosis technology, membrane core and equipment, the concentration factor that can be achieved by concentration technology is low, about 2 times, which cannot meet the higher concentration requirements
However, for the feed liquid of milk, in addition to the problems caused by the above conventional concentration methods, it is also necessary to consider that milk is a heat-sensitive substance, and heat treatment has a greater impact on various physical and chemical, microbial and biochemical indicators of milk. influences

Abstract

The invention discloses material liquid concentration equipment. The material liquid concentration equipment comprises a temporary storage unit, a homogenizing unit and a concentration unit, wherein the temporary storage unit comprises a storage container to store material liquid to be concentrated; the homogenizing unit is arranged in the downstream part of the temporary storage unit, and is usedfor exerting scheduled temperature and scheduled pressure to the material liquid, so that the material liquid is refined under the effect of pressure and impact and is uniformly and mutually mixed; the concentration unit is arranged in the downstream part of the homogenizing unit, and sequentially comprises a low-pressure reverse osmosis film processing unit and a high-pressure reverse osmosis film processing unit; reverse osmosis concentration treatment is performed on the material liquid which flows past by the low-pressure reverse osmosis film processing unit under first predetermined pressure; the reverse osmosis concentration treatment is performed on the material liquid which flows past by the high-pressure reverse osmosis film processing unit under second predetermined pressure; and the first predetermined pressure is smaller than the second predetermined pressure. According to the material liquid concentration equipment disclosed by the invention, the low-pressure reverse osmosis film processing unit and the high-pressure reverse osmosis film processing film are arranged, so that material liquid can be quickly and efficiently concentrated.

Description

technical field [0001] The invention relates to a feed liquid concentrating device, in particular to a concentrating device which adopts reverse osmosis technology to concentrate the feed liquid. Background technique [0002] In large-scale industrial production, there are various feed liquids that need to be concentrated. Through concentration, the moisture in the feed liquid can be removed, thereby increasing the content of specific components in the feed liquid; or through concentration, the feed liquid can be kept in a state suitable for long-term storage. In order to meet these needs, various concentration methods have been proposed, such as methods using high-temperature evaporation. However, this method consumes a large amount of energy to heat the feed liquid, and the high temperature has potential risks to the feed liquid, for example, it will destroy some components in the feed liquid, thereby making the feed liquid useless for application. [0003] At present, t...
