How high are the requirements for temperature in marine aquaculture, and how high are the requirements for plate heat exchangers
Shandong is a major marine aquaculture province. With its advantageous geographical location, weather with four distinct seasons, long coastline, good water quality and nutrition, and strong scientific and technological capabilities, Shandong will give priority to the development of marine aquaculture in the country, of which sea cucumber is a typical representative.
The growth of sea cucumbers requires high water quality and temperature. In summer and winter, temperatures below ten degrees or above 25 degrees will slow growth or enter a dormant period.
Now is the late autumn season for sea cucumber fishing, and it is also a good time for plate heat exchangers to be regularly overhauled, replaced and renewed.
I remember that about ten years ago, it can be said that the plate heat exchangers used in the sea cucumber farming factory in Qingdao Jimo were all from Qingdao Ripute. The editor had popular science before. One is that there are more microorganisms in the sea, and some of them will adhere to the plate heat exchanger.
Because of the blockage on the heat exchanger, the requirements for the groove depth of the plates are higher; the second is that the corrosive nature of seawater requires higher material requirements for the plate replacement; the third is that compared to the shell-and-tube heat exchanger used before, the plate type can be reduced
It occupies a floor area and has relatively high heat exchange efficiency. RPT's plate exchange operation costs are low, which ensures the profit margin of marine aquaculture.
