Abstract
The invention relates to an energy-saving air preprocessing method used for the fermentation industry and a device thereof. Compressed air is introduced into a finned air cooling dehydrator device so as to lead the temperature of cooling water in a first group of tube boxes to be raised, then the hot water is divided into two parts, wherein one part enters a refrigerating unit as a hot source to produce chilled water, and the other part enters a finned air heater as a hot source to heat air; the hot water after exchanging heat by the refrigerating unit and the finned air heater returns the first group of tube boxes of the finned air cooling dehydrator device; the chilled water generated by the refrigerating unit enters the last group of tube boxes of the finned air cooling dehydrator device to cool air; and the chilled water after exchanging heat returns the refrigerating unit for cooling again. The invention uses the finned air cooling dehydrator device to absorb the waste heat of the compressed air and uses the hot water as the hot source of the refrigerating unit and the air heater, thus being energy-saving and environment-friendly; and by adopting the air cooling dehydrator device and the finned air heater, the heat exchange efficiency is high.
Description
(1) technical field
The present invention relates to the pressurized air pretreatment technology of fermentation industry, be specially a kind of energy-saving air preprocessing method and device thereof.
(2) background technology
The aseptic dried compressed air supply that the aerobic fermentation industry need to continue.Can become the air of high temperature, high humidity after the compression of the compressed machine of air, can not be directly for fermentor tank, after must passing through the air pretreatment device and lowering the temperature, remove moisture content, become dry air, just can send into down one filtering system.
Traditional pressurized air pretreatment technology flow process, as shown in Figure 1:
From out 120 ℃～170 ℃ pressurized air of compressor → enter one-level shell and tube cooler 1 be cooled to 50 ℃～70 ℃ → enter 2 minutes water of one-level whirlwind water trap → enter secondary shell and tube cooler 3 be cooled to 25 ℃～30 ℃ → enter 4 minutes water of secondary whirlwind water trap → enter tube still heater 5 be heated to 60 ℃～75 ℃ → enter at last that filtration system filters becomes sterile air → enter seeding tank, fermentor tank uses.
