Pulsation vacuum sterilizer water cooling device and cooling method

Abstract

The invention discloses a pulsation vacuum sterilizer water cooling device and a cooling method; the device comprises a water inlet (1), a steam pressurization chamber (2), a steam inlet (3), a cooling mixing chamber (4), an outlet (5), an inner pipe (6), and outer pipes (7); a steam discharge port of the sterilizer is connected with the steam inlet (3); the steam inlet (3) is located at one end of the inner pipe opening; the other end of the inner pipe (6) opening is connected with a cooling water discharge pipe; the water inlet (1) is disposed at the middle section of the upper part of the outer pipe located at the outer side of the cooling mixing chamber (4); the device is also characterized in that a plurality of steam pressurization chamber inner pipe holes (8) and cooling mixing chamber inner pipe holes (9) with uniform sizes are distributed on the inner pipe (6); the outer pipes (7) where the steam pressurization chamber (2) and the cooling mixing chamber (4) are located are seamlessly welded outside the inner pipe (6) respectively. With the high-pressure spraying method and unique design of the cooling device, the invention realizes full mixing of steam and cooling water, and thus realizes high-efficient cooling.

Description

technical field [0001] The invention relates to a high temperature and high pressure sterilizer, in particular to a water cooling device for a pressure steam sterilizer (such as a pulse vacuum sterilizer), and a cooling method for reducing the steam temperature when the device is used for steam discharge. Background technique [0002] Hospital disinfection supply centers and pharmaceutical factories require extensive use of high temperature and high pressure sterilizers such as pulse vacuum sterilizers and washer-disinfectors. These two types of medical equipment will produce hot steam and hot water that need to be discharged during operation, and most users often use PVC pipes for drainage, which cannot withstand high temperatures, and if the large amount of steam and water discharged are not cooled effectively, It can reach 70-130°C, which not only affects the operating environment of personnel, but also easily damages the exhaust and drainage pipes, and is more likely to ...
