Energy-saving type pulsation vacuum pressure steam sterilizer

Abstract

The invention discloses an energy-saving type pulsation vacuum pressure steam sterilizer which comprises an inner chamber, a jacket, a heat exchanger, a vacuum pump, a steam generator as well as a multifunctional water tank, wherein the sucking end of the vacuum pump is connected with the inner chamber through the heat exchanger; the air outlet end of the vacuum pump is connected with the water inlet of the multifunctional water tank; the water outlet of the heat exchanger is connected with the water inlet of the multifunctional water tank; the water inlet of the heat exchanger is connected with a tap water pipe; the inner chamber and the jacket are respectively connected with the water inlet of the multifunctional water tank through drain valves; the gas outlet of the steam generator is connected with the gas inlet of the jacket, and the gas inlet of the steam generator is connected with the water outlet of the multifunctional water tank; the steam is accommodated into the multifunctional water tank by the air outlet end of the vacuum pump; operating water accommodated in the heat exchanger is accommodated into the multifunctional water tank by the water outlet of the heat exchanger; condensed water inside the inner chamber and the jacket is also accommodated into the multifunctional water tank; steam and operating water accommodated by the multifunctional water tank are repeatedly conveyed to the steam generator to generate steam for sterilization. Repeated use of water and energy is achieved.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a pulsating vacuum steam sterilizer in medical instruments. Background technique [0002] In the medical industry, the pulsating vacuum steam sterilizer is a relatively common sterilization equipment, which uses high-temperature steam to sterilize medical devices. The prior art pulsating vacuum steam sterilizer is provided with an inner chamber, a jacket, a heat exchanger, a vacuum pump, a high-pressure water pump and a steam generator, wherein the inner chamber discharges the condensed water in the inner chamber to the exhaust pipe through a trap valve , the jacket discharges the condensed water in the jacket to the exhaust pipe through the trap, and the water in the heat exchanger and the high-temperature steam in the vacuum pipe are fully heat-exchanged and then discharged into the exhaust pipe, and the vacuum pump will The steam and water in the vacuuming pipeline and the ...

AI Technical Summary

Problems solved by technology

[0004] This pulsating vacuum sterilizer requires a considerable amount of water to supply water to the sterilizer and perform heat exchange on the heat exchanger. In this process, this part of the water is not reused, but the water is directly discharged, which is wasteful. There are a lot of water resources; moreover, the water has a certain temperature, and the energy in this part of the water has not been used reasonably and effectively. The high-temperature water is directly discharged into the sewer through the exhaust pipe, and its temperature is too high to meet the national discharge standards. It is also a waste energy
